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.
Models include:
2 MP ColorVu Fixed Bullet Outdoor Network Camera (DS-2CD2T27G1-L)
2 MP ColorVu Fixed Outdoor Bullet Camera (DS-2CE10DFT-F)
2 MP ColorVu Fixed Turret Outdoor Network Camera (DS-2CD2327G1-LU)
4 MP ColorVu Fixed Bullet Outdoor Network Camera (DS-2CD2T47G1-L)
4 MP ColorVu Fixed Turret Outdoor Network Camera (DS-2CD2347G1-LU)
Hikvision's new ColorVu cameras have the following features:
LARGE APERTURE
• With a large lens aperture of ƒ/1.0, four times more light than conventional cameras is captured, resulting in brighter images.
ADVANCED SENSOR
• Latest advanced sensor technology provides a higher utilization of light, because more light enters the sensor.
SUPPLEMENTAL LIGHT
• Soft white LEDs guarantee colorful images in complete darkness. They provide crime deterrence as well as walkway lighting.
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 color 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 color 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 colorful, 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 colorful 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 color 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 color 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 color. So, though external lighting conditions are poor, even completely dark, Hikvision ColorVu Cameras still capture valuable color information.
