Hikvision ColorVu CCTV Cameras
Hikvision ColorVu Cameras – Capture Vivid Chromatic Images in Darkness.
Most CCTV cameras seem to produce similar quality images when placed outside in broad daylight but it’s a very different result when images are viewed at night. They become blurry, white washed, ghost like. The new Hikvision colorVu range of CCTV cameras are here to change night time viewing with its Ultra , ultra low light lux level of just 0.0005 in colour for a 2MP camera! Compare this to an 8MP darkfighter CCTV camera model number

ColorVu CCTV cameras are availiable in analogue for coaxail cable & IP for cat5/6 cable use. To produce images in colour in no light conditions, the cameras have built-in white light LEDS, much like your home LED lighting.
In normal street lit situations, you will get colour images and the builtin white light is switched off by default.
Today, to effectively solve the ghostly images 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 – leading to the prosecution of criminals.
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 previous decades.
As we have always stated, its NOT just "the more the mega Pixels the better quality the image". There are other factors which determine the picture quality especially in low light.
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.
1The amount of light entering the F1.0 aperture is four times that of F2.0.
Hikvision ColorVu 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 ColorVu Cameras’ high-sensitivity is designed for surveillance applications where high resolution colour images are required even in ultra-low light environments. Hikvision ColorVu Cameras sensors demonstrate an extraordinary photovoltaic conversion efficiency. They employ an advanced sensor technology – a new light-collection structure that vastly improves the utilization of light. Tests show ColorVu 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.
In addition, extreme light conditions are taken into consideration in the design process. ColorVu cameras are equipped with warm supplemental light, so when there is no light source whatsoever – even starlight or street lights – they can guarantee colourful imaging. This feature provides environmentally-friendly, soft, warm lighting, reducing any harsh discoloration 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 investigation. However, when the vehicle is non-licensed or the license 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 ColorVu Cameras still capture valuable colour information.
