The DH-IPC-HDW3549H-ASPV-S3 is a 5MP full-colour fixed-focal eyeball WizSense network camera. It is the latest in the company’s TiOC (three- in-one camera) line which integrates 24/7 full-colour monitoring, active deterrence and AI into one solution.
It is IP67 protection rated with a sturdy metal casing, with an operational temperature range stated as -40°C to +60°C. Optional junction box, wall, ceiling extender and pole mounts are available.
Getting started
The camera is PoE fed, 2.5W basic to 8.0W maximum with all lights and alarm sounder operational. Alternatively, the camera can be supplied with 12v DC at 2.5 to 7.3W.
The multi-way connector lead has an RJ45 network connector along with a 12v power jack, a pair of phono (RCA) sockets for audio in and out, and a four-way flying lead for alarm input an output and associated ground connections.
By default, the camera is not DHCP enabled and has an address of 192.168.1.108. This can be discovered on the network using the Dahua “ConfigTool.exe” program that is used to initialise the camera and set the required administration password. Once initialised, the camera can then be browser connected to set a suitable static IP address and begin configuration.
When first set to a UK location, the camera uses GMT, but Daylight-Saving Time dates can then be entered and the function enabled in System, General, Date and Time setting through the menu tree.
Just three fixing holes are required and an access hole for the cable feed of around 20mm. While a water-proof cover is provided for the network connection any unused connectors and cable must be suitably protected if installed in a location where water penetration is possible. The camera sphere can be manually panned, tilted, and rotated to suit the viewing angle for the mounting surface.
The camera can locally record to a micro-SD card of up to 256GB, to a NAS, or using Secure FTP and these can be recordings and / or snapshots by Schedule, Motion detection or on Alarm trigger. The card slot is readily accessible at the base of the camera globe along with a factory reset switch.

Menu options
The HDW3549 has a familiar Dahua web browser page with Main option tabs down the left-hand side of the window for Camera, Network, Event, Storage, System, and Information. The page can be called up with all major browsers including Microsoft Edge, Microsoft IE11, Google Chrome, and Mozilla Firefox. However, the IE11 browser gives top right-hand icons for Digital Zoom, Triple Snapshot, Record and Talk in addition to the Relay-out, Warning Light, Alarm, Snapshot, and Audio on all browsers.
The Camera tab accesses all video and audio settings such as Main and Sub stream settings, Day / Night illumination and profiles.
The Network tab is used for all TCP/IP and Port settings including, PPPoE, DDNS, SMTP, UPnP, Bonjour, Multicast, 802.1x, QOS, along with P2P, ONVIF, and RTMP.
The Event tab opens the Video and Smart Motion Detection setting pages. Smart Motion, IVS, Alarm, Abnormality and Disarming. A graphical display of signal level simplifies Audio alarm sensitivity and threshold setting.
The Storage tab accesses Scheduling, Recording destination and Control method. It is also used for formatting the micro-SD card for first use.
The System tab access General Time & Date settings including NTP server address, User Account details, Safety (enabling of services such as ONVIF and HTTPS), Factory Defaulting, firmware management plus maintenance options such as auto-reboot timing.
The Information tab shows relevant version details, Log files and Online User data.
Four areas of Privacy masking are available, and four regions of interest can be set for bandwidth limited image transmission.

Performance
The 1/2.7”, 5MP sensor has a maximum resolution of 2592(H) x 1944(V) pixels which is only available on the Main stream. This gives it a 4:3 aspect ratio that does not necessarily match the majority of modern display formats. As an alternative a 4MP 2560 x 1520 setting can be used to provide a 16:9 format output. This adds a minimal amount to the horizontal view but loses some from the top and bottom of the full imaging area. The 2.8mm F1.0 lens has a viewing angle of 103°(H) x 53°(V) at full resolution, a 3.6 mm alternative is available with 81°(H) x 43°(V).
The camera supports up to three video streams with the ‘Main’ stream having five resolution options from the maximum down to 1280 x 720. The highest resolution has a frame rate up to 20 fps and all others up to 25. Sub-stream 1 offers 704 x 576 (D1), 640 x 480 (VGA) or 352 x 288 (CIF). Up to 25 fps is available with a default of 20. Sub-stream 2 is disabled by default and offers 1920 x 1080 (1080p), 1280 x 720 (720p), 704 x 576 (D1), or 640 x 480 (VGA). 1080p mode is limited to 12 fps with all others up to 25 with a default of 12. All streams support encoding to H.265, H.264H, H.264B or H.264, while substream 1 additionally supports MJPEG.
Sub-stream 2 gives an option to “Video Clip” the image to feed just an area of interest. A small video window is shown to allow the scene of interest to be selected. At 1080P this is a simple 16:9 box of half the screen area that can be moved around, and for 720p it is moveable and scalable. The D1 and VGA options allow the 4:3 box to be moved and resized.
The camera has two-way audio channels with a built-in microphone or Line Input selectable. Audio output is fed to the internal speaker or via the Line Output cable. This allows good voice communication with the control site to notify or warn intruders or to communicate with out-ofhours visitors. Alternatively, a range of prerecorded messages or an alert siren sound can be alarm initiated providing a clear automated message from its downward facing speaker. Additional messages and sounds can be recorded and uploaded to the camera using 16 bit .wav format files.
The camera provides good colour images at very low light levels with built-in visible lighting available if there is no natural light and infrared for extreme low light performance. The 120dB dynamic range gives good scene contrast. Dahua state a sensitivity of 0.003 Lux. There are two apertures beneath the lens that are used for the illumination. A visible LED at the right-hand side provides a warm-white (yellowish) light that ensures good colour rendition. Its brightness can be adjusted from 0 to 100 or set to automatically adjust to scene content. Additionally, an infrared LED is included for low-light, monochrome images if required. This has a similar level range. The camera supports Scene settings that can be used for different requirements or scheduled.
While not obtrusive, the light gives a clear even illumination of the scene and reaches the specified 30 metre range. The left-hand side LED pair is used to provide a warning light that alternately flashes Red and Blue while active with an adjustable flash rate and duration.
The Alarm configuration is relatively straightforward and supports all of the usual features such as Tripwire and Intrusion. When motion detection is set to detect just humans and / or vehicles, it correctly ignores animals moving around the field of view. When used with the Dahua Smart NVR, the camera supports intelligent search capabilities.
Conclusion
A very capable Eyeball style dome that has a wide range of features to help detect and deter intruders, with extensive cyber security settings.
