Closed Circuit Television Camera

An example of a closed-circuit television camera is one that broadcasts visual signals to a private group of monitors or recorders as opposed to using public radio. The phrase "closed-circuit" denotes that only a restricted group of individuals or devices with permission can view the video broadcast. Analog and digital cameras are both available. It was Walter Bruch who invented the CCTV camera.
