What is CCTV ?

Closed Circuit Television simply means that the signals picked up by the cameras are not broadcast over the air, or to a public cable net, but are fed directly to monitors. This may not be fully correct for wireless outfits, but then the range of effective broadcast is minimal, and there is only one intentional receiver. Camera performance depends largely upon the reflected light at the scene to be surveyed and upon the quality of the imager or sensitive element. A few fundamental CCTV-surveillance related concepts play an important role when coming to select a CCTV Surveillance system. These terms are listed hereafter: • Video signal • Illumination • Lighting • Sensitivity • Resolution
