PSI PRODUCT REVIEW 2022 Hikvision

A winning year for ColorVu

The camera features high-quality, 8MP resolution for detailpacked pictures, along with ColorVu technology for 24/7 full colour images in even the darkest of lighting conditions

In 2021 the DS-2CD2087G2-LU camera from Hikvision caused a stir in the market with a PSI Premier Award win and a score of 9/10 in a PSI test, the highest marks of the year given to any camera

The DS-2CD2087G2-LU Pro Series Mini Bullet with 8MP and ColorVu technology is a minimarvel, pairing its small form factor with powerful cutting edge features – an accessible, performance-orientated device designed to make end user systems as effective and efficient as possible, both in detecting threats and in searching for evidence. Furthermore, in 2021 the DS-2CD2087G2-LU Pro Series Mini Bullet was the winner of the PSI Premier Award for CCTV Product of the Year as voted for by UK installers.

The camera features high-quality, 8MP resolution for detail-packed pictures, along with ColorVu technology for 24/7 full colour images in even the darkest of lighting conditions. Cameras with ColorVu technology employ advanced F1.0 lenses and high-performance sensors. That F1.0 super aperture collects more light to produce brighter images: four times the amount of light as a conventional camera. Its advanced sensor improves the utilisation of the available light, with self-adaptive 3D Digital Noise Reduction removing noise and ensuring full motion video. It can capture full colour images down to as low as 0.0005 lux and has a smart supplemental white light for zero-light conditions.

It also includes AcuSense technology for automatic human and vehicle target classification and reduced false alarms, as well as an in-built microphone for real-time audio security.

The Pro Series Mini Bullet Camera makes the most of its transmission capabilities by using efficient H.265+ compression technology to provide high-quality images while preserving bandwidth, and offers up to 256GB of local storage if required. The camera’s 130dB WDR technology means clear pictures can be obtained even in strongly backlit scenes. It is IP67-rated water and dustresistant.

What is Hikvision ColorVu technology?

Many cameras default to monochrome operations as the ambient illumination decreases, and when additional lighting such as infrared lamps is used, images lose all colour detail. While the images might be crisp and clean, the advantage of using colour information is lost.

ColorVu Technology enables the camera to capture video containing colour information in a range of conditions, including in extremely dimly lit environments. This not only gives the operator or security teams more information about a suspect, but it also makes it simpler to identify targets in dark scenes. When using conventional cameras with infrared lighting for night-time monitoring, people, vehicles, and other critical objects can blend into the dark background, making it difficult for operators to quickly assess a situation, or make positive identifications.

Hikvision’s ColorVu technology has the ability to capture colour details in low lighting. This is due to advances in lens technology and the use of highperformance sensors. The cameras also include a supplemental light for extremely dark situations.

The cameras make use of an F1.0 aperture, which captures four times the light of typical cameras. This enhances colour replication in poor lighting, without the need for excessive exposure times which can result in blur and smear. The advanced image sensor uses self-adaptive 3D digital noise reduction to eliminate noise and ensure full-motion video.
