Why is the image of the surveillance camera black and white

Camera is generally used as a CCD photoreceptor, no special requirements will generally be processed into black and white, this back-end signal processing issues.

Surveillance camera is a semiconductor imaging device, with high sensitivity, glare resistance, small distortion, small size, long life, anti-vibration and other advantages. Surveillance cameras security prevention system.

The generation of images is currently mainly from the CCD camera, can also be stored charge out of the voltage change, with anti-vibration and impact characteristics and is widely used.
