Finally¡..A Camera That Can See In The Dark Without IR LEDs
Boston, Massachusetts: January 15, 2008
A starlit sky is an amazing sight to behold, its intensity and charm can differ greatly depending on the place you are viewing from the Earth.
Starlight and moonlight have inspired generation of poets , but few people know that the power of starlight and moonlight has been harnessed by video surveillance technology developed by I VISION.
I VISION¡¯s starlight technology amplifies and maximizes existing light to generate pictures in extreme darkness . The technology is able to get better low light images without actively creating visible light.
In developing the Starlight technology, I VISION used a fusion of existing technologies and techniques and packaged them in a way that other companies had never done before.
The camera consists of two main parts, a CCD and a DSP or Digital Signal Processor. The CCD takes the picture and sends the information to the DSP, which analyzes and reproduces of what the CCD has sent it.
Infrared has been used for low light surveillance for years, but this technology has known to limitations. Overcoming these limitations to give installers a more reliable, higher quality image was the impetus for I VISION to develop the Starlight series.
The performance of infrared-technology-based cameras can be affected by either lack of reflected light or an overabundance of reflected light. This can either reduce the camera¡¯s range of view or result in an unusable image. In a example: snow-covered scenes an infrared camera is getting an 80 percent reflection. Grass only has a 20 percent reflection; water, less than a 2 percent reflection. Practically a 30 meter-range camera looking at snow it gets up to 30 meters, but if the camera is looking at grass or water, the view might be only 5 to 10 meters.
With the Starlight cameras, THERE IS NO RANGE LIMITATION. The camera is capable of reproducing views that are kilometers and kilometers away. Because the technology does not use an active light source, the board produce minimal heat, which results in a better environment for the camera¡¯s electronics.
