Hikvision Color-Vu offers clear vision at night

Hoofddorp, The Netherlands

Although security camera systems are becoming more commonplace in urban parks in recent years, there are still many security requirements that cannot yet be met, such as high-resolution night vision and recording in colour. To effectively solve this problem, cameras equipped with Hikvision Color-Vu Technology extend and enhance surveillance capabilities into the dark, lifting the cover of night to capture vivid chromatic images – and often leading to the prosecution of criminals.

Hikvision Color-Vu 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, Color-Vu 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 Color-Vu camera lenses also feature broad-band 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 kind of key information that gets blocked by a light flare.

The Color-Vu cameras’ high-sensitivity is designed for surveillance applications where high resolution colour images are required even in ultra-low light environments. Hikvision Color-Vu Cameras sensors demonstrate an extraordinary photovoltaic conversion efficiency. They employ an advanced sensor technology – a new light-collection structure that vastly improves the utilisation of light. Tests show Color-Vu cameras continually provide colourful, sharp images right down to the lowest light levels. At the same time, their self-adapting 3D DNR algorithm on ISP guarantees high imaging quality.

Color-Vu cameras are equipped with warm supplemental light, so when there is no light source whatsoever – even starlight or street lights – the company guarantees colourful imaging. This feature provides environmentally friendly, soft, warm lighting, reducing any harsh discolouration of the object being illuminated.

As a result, Hikvision Color-Vu 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 investigation. However, when the vehicle is non-licensed or the licence plate is deliberately obscured, the vehicle can only be investigated by its features – brand, model, and especially the colour. So, though external lighting conditions are poor, even completely dark, Hikvision Color-Vu cameras still capture valuable colour information.

Hikvision Color-Vu Technology is being used in the Turbo HD 5.0 and Easy IP 4.0 series.
