Case Study

INSTALLER, MANAGERS SPEAK De Montfort University sought to maximise the safety and security of its 20,500 students and 3,240 staff. The Leicester-based university has a NetVu Connected surveillance solution from DM Fusion member Security Design Services, featuring CCTV systems from Dedicated Micros.

Campus-wide solution

he scheme includes the linking back, over fibre, of 21 dispersed campus buildings - using a number of Digital Sprite 2 DVRs (Digital Video Recorders) and the associated NetVu ObserVer GUI (Graphic User Interface) - to a new control room in the Estates Services and Security building on campus. Also installed: 26 smaller ECO DVRs to link-back 26 lifts at various locations across the campus, over the network, and has also started a rolling upgrade of cameras by fitting the latest Dennard 2060 and 2040 dome cameras - including those at the multi-million pound Kimberlin Library - for internal and external monitoring. Steve Critchlow, General Manager, Security Design Services, said: “The project was initiated back in May 2007 and from the start it was decided to adopt Dedicated Micros solution to deliver the key elements of the project. Going down the NetVu Connected route has allowed us to put the Estate Services and Security team in a position to monitor CCTV cameras across the campus by removing the legacy - and disparate - monitoring systems.”

Scaling up The NetVu Connected solution at De Montfort can be scaled-up with new cameras or DVRs dropped-in with minimum disruption to day-to-day operations, the installer added. Morgan Lloyd, Security Team Leader, who is responsible for control room operations at De Montfort, was a supporter of the upgrade: “I could appreciate from talking to Security Design Services that the networked CCTV was going to make our lives much easier, especially having a centralised system. With remote monitoring and compatibility between the various NetVu Connected elements we are able to respond faster to situations as they develop.” In 4

Inside the De Montfort control room, Morgan Lloyd and Steve Critchley specifying the CCTV solution for De Montfort, Steve Critchlow’s team at Security Design Services had to take account of issues on the ground, typical of a campus in a city.

Campus issues According to Mr Critchlow: “At the start of the process when we were discussing the CCTV infrastructure with De Montfort it was clear that the key security challenges included: student and public safety on campus potential assaults, the security of the adjacent car parks, prevention of damage to buildings or other property

such as graffiti, burglary and personal theft and potential traffic accidents. These all had an impact on the positioning of cameras – the lifts being a case in point - and number of DVRs required.” The CCTV upgrade is part of a wider university plan as Kevin Burrows, Head of Security at De Montfort says: “This is a pivotal element of a five-year security programme to ensure that we have cutting edge solutions in place to meet our future needs.” Carol Cope, Partnership Manager at Dedicated Micros, who runs the DM Fusion partnership scheme, says: “It is good to see Security Design Services as a DM

Fusion member involved in such an ambitious project and we welcome the positive comments from De Montfort regarding the benefits of the NetVu Connected solution based around CCTV systems from Dedicated Micros. More and more we are finding that large scale sites - including schools, colleges and universities - are adopting this seamless approach to satisfy their security demands.” ❐ ● For more about DM Fusion in the UK and Ireland: www.dmfusion.net

CCTV evidence from Dedicated Micros – part of AD Group - helped to secure

the recent conviction at the Old Bailey of five men involved in the £53m raid on a security depot in Tonbridge, Kent, in February 2006. Images recorded by DM’s BX2 digital CCTV recorders installed at the depot and broadcast on TV nationwide helped police to piece together events on the evening of the raid. Pauline Norstrom, Worldwide Head of Marketing at DM, said: “Images from CCTV cameras both inside and outside the depot were readily made available by DM to the Police’s investigating team for evidential purposes. Some of

these high quality images were also presented in the initial press conference seeking information about the incident. It is important with any investigation to be able to access this valuable material and for us as manufacturers of such systems to provide support and assistance to the authorities. This positive outcome underlines the importance of CCTV in the fight against crime of all types.” ❐

Case Study

TRANSMISSION OVER NETWORK

Looking after the Manor Given the need to protect pupils, staff and property, Manor High School in Leicestershire turned to local CCTV installers Tranter Fire & Security.

ranter in turn specified a solution based around Bosch Security Systems (BSS) products. More than 40 cameras – a mixture of Bosch Dinion and Flexidome devices – are installed at strategic points around the school such as entry and exits, corridors and cloakrooms. Images from each camera are transmitted over the school’s own local network and stored digitally on one of three Bosch Divar digital recorders. All ancillaries including Bosch LCD monitors and keyboards are provided, as well as the appropriate operational software and storage management software. Authorised staff are able to monitor and review images from a local monitoring suite within the school’s premises’ office. Tranter chose the technology due to its reliability and performance, Leigh Tranter says: “Bosch came to demonstrate its technology to us and we were immediately impressed. Although slightly more expensive than other

products on the market, we were certain of its benefits, and managed to convince the school management that quality counts.” Leigh believes they gained from promoting the Bosch brand: “Bosch is a household name, synonymous with quality engineering. This definitely helped in selling the solution, as well as the technical backup and support provided by the team which has been second to none.”

Chips The Flexidome cameras installed use 15-bit imaging technology – the same technology already in its Dinion cameras – to exploit the potential of imaging chips. With their 540 TV-line resolution, Flexidome cameras are able to produce extremely sharp and detailed images and handle difficult lighting conditions, including an Auto Black feature to counteract the effects of fog or glare, NightSense to compensate for fading light, and backlight compensation to ensure clear images when viewing entrances.

Playback The Divar digital recorder series comprises what the makers call compact, low profile units that combine flexible digital recording and multiplexing, not only saving space but also ensuring integrated functionality. Designed with installer and operator in mind, Divar allows simultaneous recording and playback of video images, and an ‘overwrite protection’ feature of marked video clips prevents the loss of evidential material.

Record rate The images per second (IPS) record rate and image quality are selectable for each of the 40-plus cameras, thereby making it possible to prioritise recording between the high-risk and lower-risk areas. By having a higher refresh rate for critical areas, considerable hard disk storage space can be saved. Recording rates of 50 IPS (PAL) or 60 IPS (NTSC) are guaranteed, without the need for synchronisation. As well as control and external alarm inputs, the Divar’s motion detector triggers an alarm when movement in a user-definable area of 6

the image is detected. “All of the technology was easy to install,” Leigh adds, “and the Bilinx feature that enabled cameras to be set-up remotely without having to keep going up and down a ladder saved us considerable time on site, which translates into a more efficient service.” ❐

The AVCAM, among the products offered by System Q share of the CCTV market. The courses all last a full day and are held at System Q’s 21,000 sq ft head office and training facilities in Chesterfield. For reference, this is five minutes from junction 29 of the M1.

How to book To book, ring Debbie at System Q on 01246 200 000 to reserve your place. For companies with a large number of installers who require training the company offers a flexible bespoke straining service so that the whole course can be dedicated to your staff on a day that suits your company.

Established in 1993 by the current Managing Director Paul Goodwin, it has grown from its humble roots in two rented rooms costing £40 a month to a purpose-built 1.2 acre distribution centre. Many of the UK’s biggest high street retailers use CCTV equipment made and distributed by System Q, largely due the company’s focus on realtime recording. Even the latest 32channel DVR by the firm can record in real-time simultaneously on all 32 channels, and it records audio too. With a customer base of more than 15,000 installation companies in the UK, the company recalls that it was repeatedly asked if it could offer training courses on CCTV installation and networking technology. So in 2004 when the firm moved to new premises it equipped three rooms for the sole purpose of offering affordable training to its customers. In 2007, the company appointed David King to run and manage the courses. They have now been expanded, as more and more installation companies seeking affordable training. ❐

The RX504 is a rugged DVR transmitter for use in transport and rapid deployment applications. It has 120 Gb of on-board storage and enables remote viewing via GPRS networks while in motion. It includes four camera channels, multiple event inputs, four relay outputs and bidirectional audio. All TeleEye products come with local viewing, web browser based software. Further options include M303 mobile phone viewing software, SMS text capability and separate control keyboard for system management.

Compression SMAC-M achieves 40 per cent greater compression efficiency than MPEG4 because it separates the recording and transmission video streams within a DVR transmitter. This allows each RX product to record CCTV video at a user defined image quality level whilst transmitting data at any of four rates, defined by the available network bandwidth – adjusting automatically if and when this varies. The result is optimal recording and transmission quality, simultaneously. A first in the CCTV industry! ❐

EASE OF USE

Town keeps control Luton Borough Council seeks to work with the police and businesses to ensure that crime is deterred and to reduce fear of crime, and to promote community safety.

he town centre CCTV system which was installed in 1998 plays a major role in helping Luton council achieve its crime reduction objectives. Jason, who has managed the town’s Central Monitoring Centre for 10 years said: “We have been successfully using analogue recorders to capture video from our town centre CCTV system and it has worked extremely well. We became aware however that we were missing out on the advantages and benefits of using digital video technology.”

Look at market

Top: The Elite digital recorder. Below: Inside the Luton council control room Photos courtesy of Vigilant Technology

Given the level of experience and expertise in their possession, Jason and his colleagues took a long and cautious look at what was available in the market in respect of digital recording solutions and analysed what vendors were best placed to meet their criteria. There was no shortage of manufacturers keen to win such a contract. Jason added: “We got down to a shortlist of four manufacturers. With the substantial financial investment required, you only get one chance of getting it right and therefore we took our time to evaluate in some depth each of the systems from the four manufacturers. This process very deliberately included visiting a number of control rooms run by other councils to see how their digital recording systems were performing. “Whilst we wanted to take full advantage of the

12 MARCH 2008 DVR Supplement

very latest features and functions available with a digital system, what was of prime importance to us was ease of use of any system that we chose. Our operators have become very familiar with the simplicity of an analogue tape system and we didn’t want to have to introduce them to a new system that would involve protracted training.” With the process of updating their recording system, Luton embarked upon a parallel process to update their analogue video matrix and graphic user interface. The result of investigation and deliberation was a selection of true best of breed technology for the new CCTV solution. Luton’s system integrators were awarded a contract to install a Synectics analogue matrix and a Vigilant Technology Elite Series Video Recording and Management solution.

Camera total The town centre’s system has a total of 132 cameras; 84 are pan, tilt and zoom cameras, whilst the remainder are fixed cameras. Most of the cameras provide surveillance covering the town centre but there are a number allocated to viewing activity in the residential areas

of Hockwell Ring and Farley Hill, whilst there are also cameras in car parks and in and around the Town Hall. The solution provided by Vigilant, records all cameras at 12.5 images per second in 4CIF resolution and stores the data for a 21day period to error resilient RAID 5 arrays. The video from the cameras is transmitted to Luton’s Central Monitoring Centre where there are three Vigilant viewing stations. One of the viewing stations allows the operators to review recorded images, the second allows the Manager to have an overview of activity whilst the third is in the main viewing suite, which is available to the police 24-7 to allow them to retrieve evidence.

Remote viewing “We changed over from analogue to the digital video recording solution in June. By working in close partnership with Vigilant we have been able to ensure a smooth changeover and I am delighted to report that our operators have been positively surprised at how easily they are able to operate the new system.” Since the initial implementation of the recording and management system, Luton has decided to further enhance their Vigilant system implementation by taking advantage of the remote viewing capabilities provided by Vigilant Remote Gateway Server and Remote View software. ❐

COMMON PLATFORM Cutting edge products and customer service have seen Dowshu grow into the world’s largest manufacturer of 32 and 64 channel DVRs within a decade.

owshu has recently divided its entire product range into two distinct categories to help with product selection. The high capability ICON range is driving CCTV technology to new levels with all the products in this range offering customers the best functionality money can buy. The IQ range is designed to be plugged in and operational within minutes, without compromising value, functionality and specification. Both ranges enjoy the same support services. The ICON DVR range extends from four to 64 channels and uses a common Graphic User Interface. Network connectivity is standard and with Dowshu’s Networked DVR Management System (NDMS) remote access and multiple site surveillance from a DVR or PC is possible. NDMS brings live, 24/7, transmission capabilities to the range, making it suitable for use in remote monitoring stations, local authority control rooms or centrally managed multiple site retailers and corporates. Key features include:

Above: Dowshu’s Icon, and four and nine channel DVRs in the IQ range Photos courtesy of Dowshu

1) Recording at up to 400 frames per second. This means a 16 channel ICON DVR can record “Real Time” (25 frames per second) on all channels simultaneously, with live view options of up to 1600 fps. The resolution and frame rate of each channel are individually adjustable from CIF (360x288 pixels) to D1 (720x576 pixels). This allows recording quality to be balanced against recording time for each camera, making the most efficient use of available storage capacity. 2) Codec Cubic 2 compression technology. This efficient technology reduces image data size to between 18 and 30 Kb for D1 and 3 to 5 Kb for

14 MARCH 2008 DVR Supplement

Access options CIF resolutions. The net result is extended storage capacity and fast video transmission. 3) Flexible storage capacity. To meet individual application requirements, Dowshu has designed its ICON DVRs with hard drive storage slots. In practice, this allows up to 3.0 Tb of storage on board, increasing to over 16.0 Tb when linked to one of Dowshu’s mass storage solutions. 4) Data retrieval and ease of use. Dowshu excels at rapid data recall through intelligent search options, probably the most important operational function of a DVRs control software. Two such search options are: a) “Preview” search, where 24 hours of video data can be reduced to one specific minute using just three mouse clicks. b) “Instant replay” search which plays recorded video in reverse until the relevant event is found. Along with other search options, further control functions include individual camera resolution, recording speed, motion detection, audio recording, alarm handling, telemetry protocols and even full EPoS (Electronic Point of Sale) monitoring. 5) Backup and export options. The ICON range includes built in DVD or CD writers, USB ports and, via a network, PCs or mass storage devices. The software necessary to play back video data on a PC is included with the executable files, which is essential when providing evidence.

6) Reliability. This is often overlooked in DVR specification, but not at Dowshu. The company’s DVRs are made from high quality components such as ‘Server Duty’ hard drives and include guided air flow systems to cool critical components and extend life.

Channel options Dowshu’s IQ range is setting a new standard for “box to installation” CCTV solutions. Using MPEG4 compression and embedded Linux operating system, the IQ range represents value. The four, eight and 16 channel options support multiple hard drive slots and all come with three USB ports for easy video data downloading. Resolution and frame rate settings are adjustable for each camera and high quality audio is available on each video channel. Monitor outputs include composite, SVHS, SVGA, RGB and spot. The graphic User Interface makes the IQ series easy to set up and operate, using a standard computer mouse or IR remote control unit for convenience. A built in “map” feature allows for importing a map or drawing, so icons for cameras or alarms can be added for visual, on screen, site navigation. Remote access and monitoring comes as standard via Ethernet or any type of TCP/IP network. The DVRs are suitable for all applications in retail, commercial, industrial and civil markets. ❐

FROM SELF-CONTAINED TO PC-BASED

Workhorses and flagships Kodicom unveils its latest additions to its portfolio of products.

s a DVR technology firm providing several OEMs to major manufacturers ranges, Kodicom has a few surprises of its own built into its latest CCTV offering. The firm says it’s covering all the bases from the low end self contained units using MPEG4 compression, to a scalable top end multi-channel PCbased system. Each component can serve in a stand-alone mode, or be linked via its in-built Ethernet port using the CMS support software.

Stand-alone Whether it’s an all in one solution or a powerhouse in a small system the Kodicom four channel real time standalone machines provide the answer, it is claimed. Featuring full D1 resolution picture recording as well as audio, these machines are suitable for the smaller retail store where you wouldn’t want to miss a moment with your surveillance. As with all the standalone machines, there is room for multi-HDD options and multi PTZ control. The KSR304T features a half height footprint, whilst the KSR304N has an inbuilt seven inch widescreen LCD and giving you a ‘system in a box, just add cameras’. The workhorse of the range is the KSR6 series and KSR7series (in eight and 16 channel derivatives).

16 MARCH 2008 DVR Supplement

Above, a search on screen: left, the KSR304N recorder; and below, the KSR6 series, from Kodicom Featuring everything you need from a quality DVR holding up to four HDDs (up to 2TB) internally. Once again the emphasis is on quality of build and recorded pictures, like other machines in the range it shares a common user GUI, and has 10 languages available to interact with the operator. This machine is selling well, the firm reports, into the commercial and retail sectors with several contracts recently won.

16 channels The all new KSR816PRO is a 16 channel full D1 real time recording device. Many devices on the market claim to offer this resolution, but not many can do this on multiple channels simultaneously, according to the company. Once again such features as audio and PTZ control feature, as this machine really shows its true colours as the flagship of the range. DVD writer options are available as standard.

PC format Where Kodicom is unique, is in its

ability to manufacture in both standalone and PC DVR format. The latest addition to the PC range is the ND-3016. A 16 channel DVR (400fps) D1 recorder, featuring record and playback picture quality. Where this model really scores is in the SMART SEARCH functionality. Up to six types of search may be found in its menu including object search, alarm or events, and POS. Full PTZ capability is also availability, with the first Hybrid machines pulling in IP cameras available early this year.

Dome As a complement to the DVR range, a host of cameras are now available to provide quality pictures to use with the DVR range, and using the latest Sony chipsets. Starting with the KD6349VI varifocal dome camera, also incorporating standard system camera options, to the latest night vision cameras featuring in-built LEDs.

Sales and support Finally, the company introduces its new UK based sales, service and support facility based in the Midlands and provided by cctvX Ltd. The move now means that Kodicom products are held in stock ready to ship from purpose built facilities across northern Europe, and new innovations mean that demonstration equipment is available, as well as a remote CMS facility that means, according to the firm, that carrying a recorder to demonstrations could well be a thing of 473 the past. ❐ professionalsecurity.co.uk/info

NEWCOMER TAKES ON VIVID A market newcomer, StreamScale Ltd has acquired full intellectual and commercial rights to the Vivid digital video recorder (DVR) from the administrators of Baxall.

new St Helen’s based company, its founders are: Pete Diamond (former Head of Development at Dedicated Micros, founder of BraddaHead and Technical Director of Baxall), Andy Heaton (Senior Software Engineer at BraddaHead and Baxall) and John Humphrey (former Group Managing Director of Dedicated Micros, founder of BraddaHead and Verint’s VP IP Infrastructure Solutions). Pete Diamond said: "Having developed the original Vivid at BraddaHead before we sold it to Baxall in 2004, we were ideally positioned to re-acquire Vivid and further develop it. Vivid was always a much more feature-rich product than most people realise and,

to be honest, Baxall really under-sold the product by positioning it as just another DVR rather than focusing on its many more sophisticated features."

Compression For example, the men say, most people don't realise that Vivid features a full SNMP v.3 implementation, including a fully documented MIB, that provides a relatively simple, yet powerful means of controlling and integrating a Vivid into a network using industry standard IT tools and techniques. Vivid also features JPEG2000 image compression - one of two image compression techniques selected as the international standard for biometric images and it is claimed suited for the application of video analytics. Other features: a frontpanel USB port, for downloading images and unit configuration files, a range of integrated telemetry protocols, and multi-lingual user interface and

menus. The Vivid will be available with six, ten and 16 camera input options and with disk sizes ranging from 80gb to 1tb, making the product suitable it is claimed for a range of applications from small retail units through large offices. StreamScale has already enhanced the Vivid FSK DVR specification to 50pps and has included all the peripheral ports (SCSI, S-video, and audio) as standard that Baxall previously charged as options. The DVR also comes with LAN viewing software, is fully ROHS compliant and backed with a full 24 month warranty. StreamScale will be selling existing Vivid stock bought from Baxall initially, and is developing an new range of video analytics enabled digital video (analogue and hybrid analogue/ IP) and network video (IP only) recorders. ❐

UPGRADE FOR COUNTRY HOTEL

Hybrid range

System tackles tipping

Vista has launched Blade, a range of what the CCTV firm terms truly hybrid DVRs offering high resolution images and for systems incorporating both analogue and IP cameras. Each camera input has a dedicated codec to allow cameras to be fine tuned to suit any requirement. Any camera can be set to any compression level, in any quality, at any image rate per second. The use of macros allows the user to programme the DVR to just about any form of configuration, according to the firm, giving you full control of how you use the equipment. Blade DVRs have network inputs for connection to IP cameras with a maximum of 20 inputs: 16 analogue and four IP. Live and recorded video can be viewed over a network using MPEG-4, with control of multiple DVRs from multiple locations. All the range’s DVRs can record a full 25ips for each camera.

In the Hertfordshire countryside, Tewin Bury Farm Hotel has recently upgraded its CCTV. The AA four-star hotel is also a wedding, conference and party venue.

he upgrade consisted of replacing the existing system with nine Dynapel Interceptor PTZ domes and a CloseView tracking system; all supplied by Genie. Static Genie C5352 Digital Day/Night DNR cameras were selected to provide images in the bar, restaurant and reception areas, with all cameras fed back to two 16-channel Genie GDVR-160 MPEG4 digital video recorders. Jones Electrical, who are a Dynapel Approved Integrator, were the installers. The new CCTV system required the installation of more than 9km of Category 5e cable, mainly laid in underground ducts that link various farm buildings, including a 17th century barn. Two cables are installed to each of the Dynapel PTZ domes in readiness for the second stage of the upgrade that will see each dome having a CloseView tracking system fitted.

Track Due to the profile of many of the hotel’s visitors it is paramount that all vehicles and personnel entering or leaving the complex are positively identified. Static reference cameras can be retro-fitted alongside the Dynapel domes enabling the PTZ to track anything visible in the static cameras field of view (up to four static reference cameras can be installed per dome). When the domes are not tracking they return to a pre-set position or continue with their programmed tour. The CloseView unit already installed monitors the goods

vehicle access, which has been used by illegal fly tippers. Anyone tipping now has the driver’s vehicle registration and identity recorded. New poles were needed to provide coverage of all pedestrian entrances and the extensive car parking facilities. All poles and domes were painted black to blend into the hotel’s rustic environment.

What they say Vaughn Williams, a partner in the family owned business, said: “The new CCTV system is providing us with far superior images than the previous installation and I am expanding it further to cover other regions of the estate. We are especially pleased with level of identification that the CloseView gives and it’s helped to dramatically reduce the instances of fly tipping.” Dynapel equipment is available exclusively in the UK and Ireland through Genie. ❐

Up to four internal drives allow 160GB to 3TB of internal storage. This maximises recording duration without compromising resolution or image capture rates. Built-in are cooling tunnels to channel the air flow around the internal hard disks, the temperature of which are constantly monitored and alarms triggered should the threshold be reached. Andrew Pigram, Vista brand director, said: “The Blade range of DVRs offers customers an excellent solution at a time when IP is becoming more popular but doesn’t form 100 per cent of installations. The range has been engineered to high specifications to ensure reliability and performance is optimised at all times.” ❐

INTEGRATE WITH VIDEO ANALYTICS

ANPR option The latest line of digital video recorders from Honeywell provides unparalleled performance making Fusion III v3.5 a market leader in the DVR space, according to the manufacturer.

sources including encoders, IP cameras, domes and megapixel cameras. Hybrid DVRs have become more popular the firm says as the cost benefits of being able to deploy a variety of analogue camera sources with digital IP sources, are recognised, while also delivering more efficiency and reliability. DVRs like the Fusion III can be implemented into legacy systems with no need to update the entire network, so ensuring investments are future-proofed and can evolve as required.

Integration In addition, the DVR offers integration with the Fusion ANPR and Honeywell intelligent video analytics packages; Active Alert, Smart Impressions or People Counter. These analytics options automatically detect, analyse and classify the behaviour of people and vehicles to greatly increase event detection accuracy while it is claimed virtually eliminating false alarms. Fusion ANPR enables the detection, classification and retrieval of vehicle number plates in critical applications. This increasingly sophisticated technology frees up the time of security staff, so they can concentrate on assessing and responding to real incidents rather than being overwhelmed by false alarms. The Fusion III series is highly flexible, the makers say, giving users opportunity to

integrate it with existing analogue systems, while ensuring that future digital deployments can be integrated to run across the same system.

Fuel monitoring Using the FVMS remote management software, the system can also be implemented across a number of locations, to ensure that an entire network can be centrally monitored. This also applies to the ANPR option. Petrol stations, for example, can be linked up to a network to monitor fuel theft. The Fusion ANPR can be networked to ensure that if a drive-off theft was to occur from one forecourt, the offender could be tracked and recognised if they attempted to refuel at another location within the network. With built-in expandability, the series can record, search and transmit up to 32 analogue and digital IP video sources and up to 16 channels of audio.

Ease of use Any attempt to sabotage a camera is detected automatically ensuring all cameras in a network are functioning appropriately. Added to the flexibility in deployment and cost effectiveness of these new systems is the inherent ease of use that comes with the user interface, which ultimately helps to deliver a superior and flawless digital video recording system. â??

MEETING EVERY LEVEL OF RECORDING

The Kollector Elite; and the VDR-3 Series Photos courtesy of Vicon

s a genuine solution providing manufacturer, Vicon’s independent status gives them the increasingly rare ability to be flexible and exclusively dedicated in their approach to the fast evolving demands of the video surveillance market. Vicon’s customers understand exactly with whom they are partnering at every stage of the buying process without fear of conflicting interests. Central to Vicon’s unique total solution capability is their ability to meet every level of digital recording for every need. From four channel recording packed with essential, easy to use features at great prices, through to an almost limitless capability in digital video management in an IP environment. Capabilities like Vicon’s don’t come easy. Over four decades of experience, working with the very best in the business across the globe, will see Vicon products remain at the forefront for years to come. Vicon will not only meet all your digital recording and video management requirements, but will technically support its customers to the highest expectations without fuss, first time, every time.

An independently minded manufacturer

The launch of the Virtual Matrix Controller (VMC) typifies Vicon’s determination to offer customers a wide choice. Coinciding with the introduction of Version 4 of the ViconNet video management software platform, the VMC when combined with the KRX-3 decoder, provides new options for designing and operating a CCTV system. This enables network video streams to be sent to an array of analogue monitors, simulating traditional matrix control. In simple terms this new product empowers operators to enjoy all the benefits offered by a digital video system while exercising control of cameras, domes and recorded video via a traditional ‘matrix’.

feature is the Graphical User Interface, now ultra user-friendly. The site map GUI facility allows interlinking maps of buildings under surveillance to be used for camera selection. Operators clicking on camera icons do not even need to know where the cameras are physically connected or whether they are analogue or IP cameras. With its explorer-type tree system for "drag and drop" camera selection and quick playback via simple right mouse clicks on the video picture, it is not surprising that the software is highly popular among control-room operators. ViconNet is equipped with a bandwidth limiter to maximise frames per second and, therefore, viewing quality when only lower network bandwidth such as DSL is available. Digital video systems often limit the operator to a single playback view from a camera. This can cause problems when operators are reviewing and trying to analyse a particular incident. ViconNet allows multiple playback windows from the same video stream enabling the same incident to be run at different speeds, backwards as well as forwards or with time-point frozen images all assisting the speedy resolution of the investigation.

Other features include full, multi, Quad and sequential display options and multiple RS485 telemetry protocols with a set-up menu and four channels of audio recording. DSR-HB8000 hybrid DVR This hybrid DVR offers the best of both worlds as it can record ‘real time’ images from a combination of both IP and analogue cameras. The DSRHB8000 records at 400 frames per second and can capture images from up to sixteen cameras, four of which can be IP cameras, can therefore be

recorded at full frame rate. Also 16channel audio recording is possible while this top of the range machine has a potential on-board storage capacity of up to 3.75 TB of video. The DSRHB8000 uses a compression technology called MPEG-4+ which allows rapid, high quality transmission of data over a network and gives fastforward and reverse playback. A feature of particular interest to retailers is the DSR-HB8000’s ability to interact with EPOS systems. Video can be searched by looking for specific data or text and so suspicious activity can be quickly and easily analysed. DSR-2004 – A big performance DVR for small CCTV systems A new four channel digital video recorder, the DSR-2004, has been introduced into the UK market to offer a cost-effective solution to end-users who require a CCTV system with just a small number of cameras. Although competitively priced, the DSR-2004 using MPEG-4 compression, is able to simultaneously record high quality video images and audio in real time on all four channels. The DRS-2004 offers network connectivity over a LAN or WAN. Three separate search functions, event, time/date and time line, ensure that recorded images can therefore be easily remotely retrieved or displayed locally on a standard CCTV or VGA monitor. ❐

ACTION ON FALSE ALARMS

Transmission partnership Broken communication signal in remote CCTV monitoring systems is one of the main causes of false alarms resulting in needless police call outs.

roduct distributor ADIGARDINER (UK) has announced an exclusive supplier partnership with TeleEye; a company whose products are endorsed by the Association of Chief Police Officers (ACPO) and actively work to reduce false alarms and wasted police time. TeleEye’s DVR transmission products all meet British Standard 8418; a

guideline issued by the ACPO for the installation, operation and monitoring or remote CCTV applications. It is, according to the firms, intended to reduce false alarms and increase CCTV monitoring effectiveness without compromising on quality. Data is transmitted via dedicated ADSL (Asymmetric Digital Subscriber Line) which is supported by a secondary signal to the monitoring station should the first become broken. The data is then compressed using SMAC-M technology which separates the recording and transmission streams within a DVR transmitter to achieve better compression efficiency than the industry standard MPEG4 technology. This means that not only can high quality recording and transmission be achieved simultaneously - a first in the security industry - but this technology

Businesses that incur more than five false alarms in 12 months are penalised by reduced police response until any faults within the system have been resolved. By working with companies such as TeleEye we are actively working to reduce the number of false alarms while pioneering new technology within the industry.” ❐

A MOVE TO IT AND IP

Edging towards a network solution To Edge or Not to Edge, that is the question, says Paul Bodell, Chief Marketing Officer at IQinVision.

lot of industry talk centres on the migration of video surveillance systems from a mainframe-based architecture, embodied in the older DVR approach, to a distributed processing architecture. Let’s examine the two architectures and where our industry is heading with respect to distributed processing and what is happening on the edge of the networks.

In the beginning: mainframe With mainframe architecture, edge devices are ‘dumb’. In the old days, computers were mainframe-based and the users would sit at a dumb terminal and share access with everyone else to a centralised computer. This was in part due to the fact that computers were very expensive and it was impractical for each person to have their own. Mainframe systems offered the advantage that you only had to maintain one device. However, this system had several disadvantages as well, most notably that it was a single point of failure. If it went down, everyone went down. It also was limited in the number of people that could simultaneously access it (bandwidth) so sharing could sometimes be a problem.

Alternative In a distributed processing architecture, different devices share different parts of the load. For instance, one machine can be dedicated to serving software to whoever needs it, and each department can have their own machines for saving files that are specific to their operations. By distributing the load, you reduce the processing requirements of each of the devices, 36 MARCH 2008 DVR Supplement

thus enabling use of lower cost machines. Also, in a distributed architecture there is a lower probability that everyone will be trying to access the same machine at the same time, so the quality of service improves. And, of course, you reduce the impact of a failure of a single device while at the same time improving overall system performance. Prior to IP video systems, DVRs were the best alternative for video recording. DVRs were based on mainframe architecture and had the same challenges as discussed above for mainframe computing systems: limited bandwidth and the risk of single point of failure. Many DVRs were essentially PCs with analogue video capture cards. The PC was used to switch video, store video, and run the video management software.

Data limit Because you were relying on this "mainframe" to do so much, it was limited in terms of the amount of data it could process or the amount of bandwidth it could handle. DVR PCs were expected to receive video, digitise it, compress it, switch it, route it, decompress it, display it, index and archive it. DVRs were also frequently tasked with running basic video analytics like motion detection and image authentication. Since this was so much to ask, it’s no wonder that DVRs were often limited to 16 channels. In most cases DVRs could only record at low resolutions (NTSC or PAL), and the manufacturers would advertise by the total number of images/second that the DVR could handle. You then had to take that number and divide it by the number of cameras you were recording. For instance, a 16 camera DVR that records 160 D1 images /second could only record 10 images/ second/ camera when the cameras were actually capable of delivering 30 images/ second.

Distributed processing IP video systems, on the other hand, are principally distributed processing systems where different devices are tasked with different functionality. In other words, the processing was distributed. To do this effectively, edge devices had to get smarter to be able to handle their share of the load. IP data networks took care of a lot of this. For example, rather than the DVR determining how to route video, you could use: well, a router. Instead of the DVR deciding when and how to switch video you could use: a switch (see the trend here?). To make all this work for video, you had to do a couple of things. First, you needed to digitise the video to get it on the network. A lot of companies sold video encoders that converted analog CCTV cameras to digital signals that were all right, but you were still converting low quality CCTV images so the end product was the same. Next in 1998, CMOS IP cameras arrived that offered a true digital signal directly from the camera. Unlike the older CCTV systems, where the cameras streamed uncompressed video over coax putting the burden of compressing the video on the DVR, these high resolution digital CMOS network cameras compressed the video before it streamed them, allowing many cameras to share a single cable, and taking the load off a central processor.

Breakthroughs Over the next several years there were many major market breakthroughs including megapixel cameras in 2000 and with the availability of affordable processors, intelligence continued its move to the edge. By 2001, smart cameras were not only compressing video, they had motion detection built in so they only streamed their compressed video when they detected motion—improving the overall efficiency of the system. By 2003, images could be manipulated in the camera, like privacy masking and digital image cropping so the load on any central processing machine continued to get lighter.

Central DVR versus distributed IP So, returning to the subject of mainframe DVR architecture, we were asking a single DVR to: ● Convert analog to digital ● Compress digital video ● Switch digital video ● Run motion detection on the video ● Run digital image authentication on the video ● Index the video ● Run video management software ● Read and write video to/from the disks Is it any wonder that DVRs were limited in how many cameras they could handle? Now let’s take a look at the same tasks in an IP video system and see what the central processor is asked to do: ● Convert analogue to digital – no

need, camera outputs digital images With IP cameras, the compression is done at the camera and video leaves the camera as a compressed digital stream on the Ethernet. As such, it behaves just like any other data on your network. This means that until an image needs retrieval, the NVR server at the back end doesn’t need to do anything with the stream except record it. ● Compress digital video – done at the

camera Because the stream leaving the camera is not only digitised, it is also compressed, this saves a step in the process that would normally be done by the DVR. This also permits the video imaging to be compressed before it is transmitted, saving valuable bandwidth. ● Switch digital video – done by the

network switch/router With a DVR, all video data is directed to the DVR, and then from the DVR outward to the wider world. With an NVR managing IP devices, a stream doesn’t have to be accessed through 38 MARCH 2008 DVR Supplement

the NVR. Instead, digital image streams can be directed by the NVR to run direct streams from camera to user, with the NVR only performing management of the devices. This means video is distributed only as needed, and that distribution is done dynamically based on the immediate needs of the system. ● Run motion detection on the video –

done at the camera Because data on a network is bidirectional, that is the NVR can talk to the camera and vice-versa, IP cameras can now do things that their analogue counterparts could not. One of these functions is analytics, of which motion detection is only one of the more common applications. Using built-in motion detection on the camera, a system can be set up so that the camera determines what level of video data, if any, is sent to the NVR. So, for example, such a camera might send low resolution, low frame rate data to the NVR until a motion event occurs, at which time the camera would send higher resolution, higher frame rate data. As with IP switching/ routing technology, this allows the camera to take analytics "to the edge" and play a greater role in managing system load and bandwidth. ● Run digital image authentication on

the video – done at the camera The rule of thumb in chain-of-evidence process is the fewer the steps, the more authentic the image. Nothing is more authentic than tagging or marking an image at the capture source; it removes nearly any defensible doubt about the authenticity of an image. ● Index the video – done at the camera

Because IP cameras can also send meta-data along with the digital stream, they can self-index video by camera location, time/ date, type of event. This adds to the authentication of the video and also can save the NVR the step of having to perform this functionality at the head end. ● Run video management software ● Read and write video to/from the

disks – handled by the network storage device With a DVR, storage is limited to what’s directly on the DVR. With an NVR, storage can be any network device, local or remote, to which the NVR has read/ write authority. This allows for a distributed architecture for storage, easy adaptability for redundant storage, and an infinitely expandable storage matrix. With a DVR, if it’s a 2 Terabyte unit and you need 3 Terabytes, you have to buy an extra DVR, move some of the physical camera hook-ups to the new DVR, and physically re-route your video matrix to accommodate the additional box. With an NVR, if you have a 2 Terabyte array and you need 3 Terabytes, you simply buy an additional drive, insert it into the rack, and away you go. So, in today’s distributed architecture IP video system, the central processor or PC is generally used simply for managing the video, thus allowing it to handle a substantially higher number of cameras per PC than a DVR.

Comparison Let’s look at some other pros and cons of a mainframe DVR vs. a distributed IP video system. With a DVR, the storage is built-in. This means you don’t have to configure anything, just plug the camera in and tell it to start recording. In a distributed IP video system you have to plug the camera in and tell it where to record. The disadvantage of the built-in storage (aka a DVR) is that it is often quite difficult to add storage. So, you either have to budget the costs of all the storage you will ever need up front or plan to undergo a painful and costly field upgrade. With a distributed IP video system, you use high quality network storage that is available in all shapes and sizes and gets cheaper every day. Similar to storage, a mainframe DVR has a finite number of cameras it can deal with. If you only need 10 cameras today but think you may have to expand, you would have to buy a 16 channel recorder today. This means almost 40 per cent of your investment will be unused. If you eventually fill up the DVR Go to page with 16 cameras and need 39 another, plan on having to

CONTINUED ... FROM PREVIOUS PAGE buy another 16 channel DVR. With an IP video system, you add cameras as you need them, just like storage. If you need 10 cameras, you buy 10 camera licenses. If you add two more cameras six months later, buy two more licenses at that time, not today.

The network edge Just like the computing industry migrated from mainframe computers to a distributed PC architecture, the video surveillance industry is evolving from a mainframe DVR architecture to a distributed IP video environment, powered by increasingly smart and abundant edge devices. These devices are decentralising functions such as video analytics, compression, quality of service, video distribution and storage away from a central DVR, and moving some of those functions closer to the edge. This decentralisation is nothing new to the IT industry. In fact it was a process of natural evolution as systems moved away from a central server with ‘dumb clients’. IP cameras and NVRs are simply the video security sector’s evolution into the same type of architecture. Much of the change that has morphed the video security industry in the last three to four years, though seemingly dramatic within our own industry, isn’t really anything new under the sun. In fact, what we’re experiencing isn’t so much a move away from analogue and DVRs, so much as it a move toward the IP industry.

IT and security The Holy Grail of this effort has been the goal of a merged information architecture that seamlessly combines IT and security under a single infrastructure. As with any such unification, bringing these two previously incompatible functions under one roof requires specific design considerations, as well as a new set of installation requirements and knowhow – not the least of which is how to allow relatively large video streams and much smaller data streams live, breathe and interact with each other without either causing the other’s detriment. For years, analysts and manufacturers wondered alike when the ‘switch’ would occur within the security market from analogue to IP. We need not wonder any longer. ❐

NOISE REDUCTION Genie CCTV has launched two new DVRs since October 2007. G-DVR Quadraplex Series Genie has released a new range of QUADRAPLEX MPEG4 digital video recorders in four, eight and 16 channel versions offering 400 IPS (images per second) real time recording. The G-DVR range come standard with a built-in CD re-writer or a DVD re-writer supporting up to 3Tb storage. All the recorders come with a free client software, front USB port, remote control, and mouse for easy navigation. The GUI can be accessed and controlled from the front panel of the DVR, mouse or remote control. A built-in remote player automatically mounts on to the desktop monitor and allows image capture and playback. The MPEG4 compression allows the DVR to achieve maximum recording efficiency for the available hard disk drive. Space is extended when compared to other compression techniques. The recording function can be programmed for continuous, alarm or motion recording. Also these recordings can be scheduled to start and stop and different parts of the day. Genie adds that the G-DVR combine great performance with competitive pricing. E-DVR Triplex DVR Genie has introduced a new entry level, four channel ‘economy’ DVR with MPEG4 compression suitable it is claimed for installers on a tough budget. The E-DVR comes standard with a built-in DVD re-writer, a free client software and remote control, front USB port and supports up to 500GB storage. E-DVR offers 100 IPS recording and is suitable for situations that do not require large amounts of data retained and stored.

What is DNR? DNR is Digital Noise Reduction technology. What’s it got to do with DVRs? Genie’ Marketing Manager Binit Shah says that DNR enables pictures to be sharper and cleaner without creating any motion blur or smear and disables any ghosting effect by eliminating high noise levels that are found when lighting levels are low. Colour images with DNR applied stay sharp and clean, according to the firm, even after colour data has been lost due to the lack of light. On larger CCTV systems there is often a requirement to store large amounts of video footage therefore a need for larger recording space is required to accommodate the recording element of a CCTV system. Cameras with DNR technology can therefore offer a large cost saving by reducing the noise from an image and compressing the recorded files size by up to 70 per cent, it is claimed, when using MPEG-4 compression thereby reducing the size of the Hard Disk Drive required on a DVR. Note: The quality of the image from the camera does not get affected when the file size is compressed. Genie now stocks a complete list of cameras (bodied cameras, day-night, WDR, IR and PTZ domes) with DNR technology. ❐

EIGHT AND 16 CHANNELS

DRIVE SPACE MAXIMISED The PDR-6000 Series, the new four, eight and 16 channel digital video recorders, offer users tremendous value for exceptional performance, say manufacturers LILIN.

ith MPEG4 compression drive space is maximised by reducing video to small file sizes, without compromising image quality this results in longer recording times and high speed image transmission over networks. The PDR-6000 Series uses Seagate SV35 SATA hard drives with a maximum capacity of up to 2TB internally or 8TB in the optional external RAID drive. Users can expect to achieve 42 days per TB in ‘normal’ settings at 100fps. Designed for ease of use, the intuitive graphic interface enables simple configuration and operation via the mouse, front panel, IR Remote or LILIN keyboard. An internal DVD+RW and USB port enables fast and simple back up. The SVGA output has Motion Adoptive

Refinement with Vivid Image Enhancement for video quality on TFT PC monitors. The main monitor output has a large range of multi-screen display options with drag and drop camera placement. The spot monitor output allows the sequencing of quad displays or single images, enabling the user to show a quad on one monitor and all images on the main monitor. Users can operate and manage the system from any remote location using a web browser interface without the need to install any software. Up to 255 recorders can be cascaded providing the potential to control 4080 PTZ domes or fixed cameras from a single keyboard. ● For more details on the PDR6000 Series digital recorder, visit 440 www.LILIN.co.uk or ring sales on professionalsecurity.co.uk/info 0870 120 5550. ❐

Which is best for you? DVR or NVR; which one is best for you? To fully answer that question it is important to understand the differences between them, writes Tim Bunce of ICU Digital.

VR (Digital Video Recorder) offers an “out of the box” solution for traditional CCTV systems with everything contained in a single base unit. They can be employed as an upgrade to existing VCR/Multiplexer systems or as part of a new install. They do not require tapes, have greater reliability plus greatly reduced maintenance requirements. This had led to reduced callouts with associated cost savings. More recently we have seen a

demand for remote access, again DVRs have filled this need by use of client software over the internet or via wireless connections. NVR (Network Video Recorder) offers similar features with one significant difference, the video storage media is located away from the base unit which affords much greater amounts of storage to be used. A typical example would be to have the NVR located where security staff would have access to it but the storage media would be within a separate secure controlled area. Another benefit is that the recordings remain secure if the NVR is stolen or goes faulty. The reducing cost of digital CCTV has opened DVRs and NVRs to a wider market of both installers and end users. With remote access fast changing from luxury to essential we see a bright future for these products. ❐

Case Studies

CENTRAL VIDEO SURVEILLANCE

Technology covers ‘a small town’ A university has deployed the DVTel Latitude Network Video Management System (NVMS) to provide video surveillance throughout the entire campus.

orth Carolina State University (NC State) in the United States has more than 350 cameras in multiple departments on campus, and the university network has ample capacity for the project to scale substantially as demand dictates. One department, the AllCampus Network, manages the servers, storage, and technology while offering each campus department the opportunity to purchase and integrate the cameras they need into the campus standard. As new buildings are built or when a department expresses security concerns, the AllCampus Network serves as security consultant, with university police, providing the standards and criteria new users need to address. The parties agree on a security template for the building and the AllCampus Network provides the “customer” with budgets, project management, and technical support.

Project manager “NC State is the size of a small town,” said Scott McInturf, Project Manager, AllCampus Network, “with 35,000 students, 8000 faculty and staff, more than 2000 acres, and 500 buildings, including critical infrastructure installations such as a nuclear reactor and many other sensitive material sites. Our job is to provide the technology to efficiently and effectively protect all these assets in an urban environment with a dynamic population.” NC State spent a year evaluating network video management systems. Selection criteria included scalability, capability to fully use and sit atop the campus network, and integration with future security 44 MARCH 2008 DVR Supplement

management systems. The DVTel system was chosen because it amply met these criteria, but it also offered more, the uni reports. The NVMS provides a user friendly interface and, importantly, it easily partitions so that each individual “customer” department accesses only their video data while university police and other university staff have access to all video.

Incident review “The DVTel system met our criteria: we didn’t need a separate, dedicated security network and it has been growing with our needs as we rapidly add users and cameras,” said McInturf. Video is used for live monitoring and extensive incident review. All video is maintained in a central secure location, so departments don’t have this responsibility and the university knows that data is safe stored. Each department has access to only their camera data, and they can maintain their systems with autonomy while still being part of a larger campus-wide system that offers uniformity and economies of scale. McInturf commented that the campus access control system has more than 40 separate administrative groups and he sees video growing to that level and beyond.

Grow to thousands “With the expansion of campus and other state agencies using our system, this system could grow to thousands of cameras,” he said. The DVTel system has proven flexible, the university added. For example, for a cash counting room and in the rare books section of the library, individual cameras are programmed at higher frame rates and to store video for longer periods of time. The system has also proven effective with video data used not only to solve crimes but as a

training tool and to improve operations in convenience stores and dining halls.

Meanwhile at a sea locks application, the SceneTracker feature of iSOC was used to virtually “stitch” together each camera view so that a complete scene of the lock is available to a centrally located operator.

ersonnel view the entire lock on their monitor and open and close the gate remotely. Using PTZ features adds security. Verification of identification information is more easily accessible (for instance, markings on the boat from an angle not easily seen from a monitoring station) and the boats can be scanned if there is suspicious activity.

iSOC’s SceneTracker While traditional video management systems typically provide multiplexed or sequential views, or at best use a megapixel or panoramic camera, SceneTracker allows the world to be seen as the human eye was meant to see it with no limitation of a single camera view. With the SceneTracker feature, objects or persons of interest can be tracked, zoomed in on and hovered over for a closer, detailed view.

Logistics Using SceneTracker is logistically more efficient by replacing what used to take staff at each lock or a team of people to man multiple locks with a remote team with an improved view. Some 70 locks take cargo boats up to 300 feet long. The locks are used to control the water to stop the main land from flooding. By having a remote monitoring station, there is no need to dispatch a team to manually open and close a gate, allowing for more traffic to go through the locks. Delivery time is reduced because waiting periods are diminished. This improves the receiving and shipping of goods and provides the lock with improved statistics and improving the overall offering to the end user. There was no need to run new infrastructure because the existing network was used to support this new system. ❐

SOFTWARE AND HARDWARE MADE EASIER A glossary of terms: ADSL: A type of broadband that allows huge amounts of data to traverse a telephone network, also known as DSL, or xDSL the prefix (x) denotes the type of DSL. ADSL is asynchronous (the data travels downstream faster that upstream), SDSL is synchronous (the data travels at the same speed upstream as downstream). Bandwidth: The data transfer capacity of a digital communications system, such as the Internet or a LAN. Bandwidth is usually expressed in the number of bits that a system is capable of transferring in a second: bits per second (bps). High bandwidth or broadband refers to a network capable of a fast data transfer rate. Bit rate: The speed at which digital audio and video content is streamed from a source, such as a file, to be rendered properly by a player, or the speed at which binary content in general is streamed on a network. Bit rate is usually measured in kilobits per second (Kbps), for example, 28.8 Kbps. The bit rate of a Mpeg-4 file or live stream is determined during the encoding process, when the streaming content is created. Bandwidth is the total bit rate capacity of a network.

For audio and video content to render properly when streaming over a network, the bandwidth of the network must be high enough to accommodate the bit rates of all the different content that is concurrently being streamed.

and decompressing audio and video.

Broadband: A common term for a data link that has a fixed cost rather than an as used cost.

De interlace: To combine two interlaced fields into a single frame and render them at 30 frames per second (fps). De interlacing is done to remove artefacts and improve the quality of encoded video.

Cable: A type of broadband offered in cable equipped areas. CD quality: Audio encoded by using uncompressed PCM at 44.1 kHz and 16 bit stereo. A CD and an audio stream encoded at CD quality sound identical. Codec: Short for compressor/ decompresser. An algorithm or scheme used when recording digital video or audio. A codec is used, for example, when video is transmitted over the internet; the video is compressed on the sending end and decompressed on the receiving end. Users can select a codec based on the audio or image quality, and image size preferred. Compression: Coding of data to reduce file size or the bit rate of a stream. Content that has been compressed must be decompressed for playback. A codec contains the algorithms for compressing

A new licensable DVR platform designed specifically for the surveillance market which enables customers to get their products to market faster is announced by IT and research company MindTree Consulting and Analog Devices. The DVR product platform is based on Analog Devices Blackfin processor and the system is expandable up to 16 cameras with simultaneous recording, streaming and playback DVR/NVR. Images are deleted on an oldest first basis. FTP: File Transfer Protocol, a protocol for the transmission of files (images and movies) across a TCP-IP network – See SFTP. HDD: Hard Disk Drive. HIS: High Integrity Signalling, a part definition of EN50136 that describes the level of security applied to the transmission path for alarm signals. Equipment can have HIS accreditation which covers the alarm signalling path only, necessary where NVR images are used for alarm verification and carry the alarm trigger information. Typically only required where images are used for alarm verification. HER: High Efficiency Redundancy, a part definition of EN50136 that describes the physical aspects of the equipment/power supply and resistance to physical attack of a NVR. Normally only required where the NVR is used for alarm signalling. Intelligent streaming: A type of streaming that detects network conditions and adjusts the properties of a video or audio stream to maximize quality. Intelligent streaming is only available for content encoded using a multiple bit rate profile. Interlace: To display video by using a half-resolution image known as a field. Interlaced video uses two video fields to make a single frame of video. Each field of video contains alternating lines of an image: field one displays the odd numbered lines and field two displays the

50 MARCH 2008 DVR Supplement

even numbered lines. Interlacing saves bandwidth when the video is transmitted over the airways or on cable. Inverse telecine: The process that intelligently removes the frames that were added when 24 fps film was converted to 30 fps video. Motion Detection (See VMD): A technique for the raising of alarm or cause for recording, based on the detection of motion by pixel comparison using algorithms. ISO MPEG-4 video codec version 1.0: A type of codec based on the ISO MPEG-4 standard. It enables you to encode content produced by many consumer electronics devices, such as digital video cameras and cell phones. IP address: The address given to a NVR or a IP based camera so that it may be accessed through a LAN or WAN (See LAN/WAN). Given as either a static IP or dynamic IP, static IP addresses remain the same for the period that the connection is owned, dynamic is altered on demand by the ISP or when the lease time for an address expires. MPEG (‘M-peg’): stands for Moving Picture Experts Group, the name of family of standards used for coding audio-visual information (eg, movies, video, music) in a digital compressed format. Major advantage of MPEG compared to other video and audio coding formats is that MPEG files are much smaller for the same quality. This is because MPEG uses very sophisticated compression techniques.

ISO JPEG: JPEG (‘jay-peg’), a standardised image compression mechanism. Stands for Joint Photographic Experts Group, original name of the committee that wrote the standard. JPEG is designed for compressing either full-colour or grayscale images of natural, real-world scenes. It works well on photographs, naturalistic artwork; not so well on lettering, simple cartoons, or line drawings. JPEG handles only still images. A related standard is MPEG for motion pictures. JPEG is ‘lossy’, meaning the decompressed image isn't quite the same as the one you started with. (There are lossless image compression algorithms, but JPEG achieves far more compression than possible with lossless methods.) JPEG is designed to exploit known limitations of the human eye, notably the fact small colour changes are perceived less accurately than small changes in brightness. Thus, JPEG is intended for compressing images that will be looked at by humans. If you plan to machine-analyse your images, the small errors introduced by JPEG may be a problem for you, even if they are invisible to the eye. A useful property of JPEG is that the degree of lossiness can be varied by adjusting compression parameters. This means that the image maker can trade off file size against output image quality. You can make ‘extremely’ small files if you don't mind poor quality; useful for applications such as indexing image archives. Or, if unhappy with output quality at default compression setting, you can jack up quality until you are satisfied, accepting lesser compression. Decoders can trade off decoding speed against image quality, by using fast but inaccurate approximations to required calculations. Some viewers obtain remarkable speedups in this way. (Encoders can also trade accuracy for speed, but there's usually less reason to make such a sacrifice when writing a file.) Linux: An alternative operating system to Microsoft Windows – See Windows. Often used by DVR/NVR to provide a specialist man machine interface to equipment. Typically used in an embedded system rather than PC based. Lock down: images that are locked by user intervention from deletion by any FIFO (see FIFO) recording system. Used where images are required for evidence. Looping: The process in which filebased content is played repeatedly until encoding is completed. Looping ensures that you have no interruption in the stream as a result of reaching the end of a file before completing a Go to page broadcast or capture session. 51

especially audio signals. When you encode audio by using PCM, no compression is applied.

NTFS: An advanced file system designed for use specifically within the Windows 2000 operating system. It supports file system recovery, extremely large storage media, and long file names. It also supports object-oriented applications by treating all files as objects with userdefined and system-defined attributes.

RGB: A colour model that describes colour information in terms of the red (R), green (G), and blue (B) intensities that make up the colour.

NTP: Network Time Protocol. NVR and SNVR should use NTP to ensure that the time and date of images recorded are accurate. NTP servers are connected to the atomic clock and the time and date controller is accurate to milliseconds. NVR: Network Video Recorder, a more intelligent form of DVR (see DVR) that includes the necessary technology for transmission of images to a remote centre, can include alarm transmission. Some NVR connect to IP-based cameras. See SNVR. PAL: Phase Alternating Line: The dominant television standard in Europe. Whereas the NTSC, (National Television Standards Committee, the US standard), delivers 525 lines of resolution at 60 halfframes per second, PAL delivers 625 lines at 50 half-frames per second.

Source: The type of content that can encoded by a DVR/NVR, analogue or IP. Source group: Audio and video that are encoded into a stream and played by the Client by the use of a Mpeg-4 compliant Player. SSL: Secure Socket Layer, a layer used within TCP-IP for the secure encrypted transmission of data. SFTP: Secure File Transfer Protocol, a secure way of sending files (images and data) across a network. SNVR: a secure Network Video Recorder that uses SFTP and SSL to transfer images across a network. Necessary to meet the requirements of EN50136 (alarm signalling systems) where images are used for alarm verification.

Telecine: The film-to-video conversion system that adds frames to video to compensate for the differences in frame rates between film and video. When converting 24 fps film to 30 fps NTSC video, an additional six frames per second are added. Unicast: A one-to-one client/server connection during which the client receives a distinct stream from the server. No other client has access to the stream. Each client has its own connection to the server and a separate content stream must be generated for each client requesting content from the server. User Datagram Protocol: A communication protocol that sends a data unit or datagram from one computer to another. It does not sequence the packets that the data arrives in, but it does provide a checksum capability to verify that the data arrived intact. VMD: Video Motion Detection, acceptable for raising alarms in internal environment but remains difficult in external areas – seek advice from the Police Scientific Development Branch.

Pixel format: Colour depth of an image, usually measured in RGB or YUV.

Stream: Data transmitted across a network and any properties associated with the data. Streaming data enables the player to begin rendering the data immediately instead of waiting for the entire file to be downloaded. Used only with MPEG transmission.

Profile: A predefined group of settings that match content type and bit rate with appropriate audio and video codecs.

Target bandwidths: The number of bits that are transferred to users based on the speed of their network connections.

Windows: Operating system often used in PC based systems . Variants exist.

Pulse code modulation: A sampling technique for digitizing analogue signals,
