The simple business surveillance systems system is comprised of the camera, lens, and track, and when recorded video is necessary, then a recording device, like a VCR or a DVR. Let us first look at the camera.
The key items to learn more about the camera would be whether an indoor or outdoor application, amount of available light for the camera to view, desired resolution of this camera, and continue, wireless or hardwire in the camera to the screen.
Light levels for cameras are often measured in Lux, which is a measurement of light energy onto a surface. A normal office environment may have 500 Lux whereas a residential street light may be 0.5 – 3 Lux. Adequate color cameras frequently will have a two Lux or lower score and monochrome (B & W) cameras frequently under 1 Lux.
An excellent way to manage night vision problems is with IR lighting. IR LEDs, usually on the camera itself, provide illumination and when a color camera, at night, the camera will change to monochrome and is, therefore, basically a 0 Lux camera to the space of the IR LEDs.
