What Does lux Mean On A Spy Camera?



Specifications for surveillance cameras often include a minimum illuminance level in lux at which the camera will record a satisfactory image. A camera with good low-light capability will have a lower lux rating.

Low light capability of a camera is determined by its CCD size, lux rating & video gain in dB. Lower the lux, more the camera is sensitive to a light and higher the gain, better under low light with minimum loss of resolution. The gain is at the highest with 1/2″ CCD cameras. 1/2″ CCD cameras are also extremely sensitive to infrared illuminators. Even under total darkness, 1/2″ CCD cameras can see the room like a day if infrared illuminators are used together. The camera comes with a regulated power supply and connects to any TV, VCR or a DVR. All cameras have self adjusting electronic iris for various lighting situations. SCS cameras come in a complete package so all you have to do is just plug it in.
