Closed Circuit Television (CCTV) is a system where the circuit in which the video is transmitted is closed and all the elements (camera, display monitors, recording devices) are directly connected. This is unlike broadcast television where any receiver that is correctly tuned can pick up and display or store the signal. However, security cameras using scrambled radio waves are in fact subject to common carrier tariffs and FCC conditions of service. In the past, these signals would be transmitted to a monitor equipped with a video cassette recorder, but these have been all but totally replaced by digital video recorder (DVR) systems that can store far more video and back up data automatically.
