Hikvision AcuSense and ColorVu deliver SME security
AcuSense and ColorVu are the most advanced technologies Hikvision has developed for application in the SME sector. When deployed in combination, they have the power to significantly reduce false alarm and manpower costs.
Video surveillance has evolved from a simple requirement for clear images to video content analysis (VCA) for improved management. Now, with deep learning, security solutions are enabled with sophisticated intelligence, and Hikvision’s AcuSense now makes advanced VCA and deep learning capabilities accessible to SMEs and residential customers.
Small and medium businesses have many of the same surveillance and security requirements as larger organisations. They need to identify and react to perimeter breaches in real time, and they need automated footage searches to locate events quickly. However, conventional surveillance systems may not do the job well enough.
The need for accurate alarms
Conventional surveillance systems provide certain detection features enabled by video content analysis (VCA), such as motion detection, line-crossing detection and intrusion detection, but, they simply compound all event detections, triggering frequent alarms when an object is detected. This could be an animal, a shadow, or other natural movements – false alarms.
Investigating each alarm to rule out false triggers can delay appropriate response and is otherwise just plain inefficient.
Being able to identify verified threats – the presence of a human or a vehicle – can greatly improve the accuracy of perimeter VCA. Hikvision’s hassle-free AcuSense technology can help achieve this goal, and deliver a cost-effective way to protect sites and assets.
Enhanced alarm accuracy saves time and worry
Employing advanced VCA and deep learning algorithms, Hikvision AcuSense helps you maximise security with efficient human and vehicle detection by categorising alarm information into human, vehicle, and other objects. With high accuracy, the system disregards alarms triggered by other objects such as rain or leaves, and delivers alarms associated only with human or vehicle detection.
With Hikvision AcuSense you also get a “quick target search” feature that allows security personnel or local police to find footage quickly in the event of a security incident. This saves many hours compared to searching for footage manually.
Efficient alerts and video help you get in the know
When an intruder tries to sneak into a property on a windy and rainy day, he/ she probably thinks that the bad weather will provide good cover due to the distraction of wild and wooly weather and lack of witnesses. With a perimeter security system armed with Hikvision AcuSense technology, this is not the case.
The security camera armed with AcuSense precisely captures the intruder breaching the external perimeter. At the same time, it delivers a notification to your smartphone and a view of the video feeds. With this verified alarm, action can be taken straight away. Hikvision AcuSense prevents problems before they escalate into potential emergencies.
Hikvision’s fully-integrated video surveillance makes it easy for you to see and capture important activity with video alerts, live feeds and 24/7 digital video recording – all easily viewed from your Hik-Connect app.
Hikvision AcuSense technology can be found in the EasyIP and Turbo HD product ranges, which provide ideal security solutions for small factories, residential estates and villas, small hotels, gas stations and similar sites – indoor and outdoor.
Hikvision AcuSense key features:
• False alarm reduction – reduces false alarms triggered by inanimate objects to a minimum, vastly improving alarm efficiency and saving costs;
• Quick target search – more efficient and effective file searching based on human and vehicle classifications, preventing security personnel from having to search through footage manually;
• Strobe light and audio alarm – wards off potential intruders by combining a siren with flashing light.
Hikvision ColorVu Cameras
At around 11 pm, police received an emergency call and rushed to the scene. An assault had occured in a park. According to the victim, the attacker looked like a beggar in ragged clothes and smelled of alcohol. The victim was heading home from the park at the time of the incident, when the attacker suddenly ran out of nowhere and attacked her, took her purse, and fled.
The police investigated the scene but found no useful information about the attacker. Because it happened at night, the security cameras in the neighbourhood were unable to record any usable footage. When reviewing the surveillance video, the image was blurry and full of visual noise, which is bad for detection.
Neighbourhood parks should be a peaceful place where you can take a break from the hustle and noise of the city. However, an urban park at night is often synonymous with danger. At night, passers-by have to be vigilant to stay safe. Although security camera systems are becoming more commonplace in parks in recent years, there are still many security requirements that these don’t meet, such as high-resolution night vision and recording in colour.
To solve this problem, cameras equipped with Hikvision ColorVu Technology extend and enhance surveillance capabilities into the dark, lifting the cover of night to capture vivid chromatic images – assisting in the prosecution of criminals and ultimately enhancing safety.
As a video surveillance manufacturer, Hikvision has long developed products equipped with innovative new features based on video surveillance technologies that have been refined and improved over decades.
Hikvision ColorVu Cameras’ powerful ability to capture details in low lighting comes from two specific breakthroughs in hardware technologies: advanced lenses and high-sensitivity sensors. In contrast to conventional lenses, ColorVu lenses are equipped with a super-aperture, reaching up to F1.0, which allows more light to enter the lens so that imaging brightness can be increased.
Hikvision ColorVu Camera lenses also feature Broadband Anti-Reflection (BBAR) Coating and Extra-Low Dispersion (ED) Optical glass, to reduce light flare and efficiently reproduce an image’s sharpness and colour saturation. These technologies effectively overcome the problem of key information getting blocked by a light flare.
The ColorVu Cameras’ highsensitivity is designed for surveillance applications where high resolution colour images are required even in ultra-low light environments. Hikvision ColorVu Camera sensors deliver extraordinary photovoltaic conversion efficiency. They employ an advanced sensor technology – a new light-collection structure – that vastly improves the utilisation of light.
Tests show that ColorVu cameras continually provide colourful, sharp images right down to the lowest light levels. At the same time, their selfadapting 3D DNR algorithm on ISP guarantees high imaging quality.
In addition, extreme light conditions have been taken into consideration in the design process. ColorVu cameras are equipped with warm supplemental light, so when there is no light source whatsoever – or even under starlight or street lights – they can guarantee colourful imaging. This feature provides environmentally friendly, soft, warm lighting, reducing any harsh discolouration of the object being illuminated.
As a result, Hikvision ColorVu Cameras provide bright colour video images 24/7 in low illumination conditions. They excel at capturing vivid chromatic images in a multitude of application scenarios, such as public places with no lighting, night security at industrial parks, traffic intersections in low light environments, and many more – everywhere colour information is particularly important.
As an example, in general, license plate information of a suspect’s vehicle is crucial in traffic accident investigations. However, when the vehicle is nonlicensed or the license plate is deliberately obscured, the vehicle can only be investigated according to its features – make, model, and colour. Even in poor external lighting conditions - and even when completely dark – Hikvision ColorVu Cameras are still able to capture valuable colour information.
Hikvision ColorVu technology is being used in the Turbo HD 5.0 and Easy IP 4.0 series. More details can be found on the official Hikvision website.
