Closed-circuit television (CCTV), in addition to known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, while it may employ point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless links. though something like every video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require supplementary security or ongoing monitoring. even if videotelephony is seldom called "CCTV" one exception is the use of video in disaffect education, where it is an important tool.

The growth of CCTV has been slowing in recent years. The deployment of this technology has facilitated a significant deposit in confess surveillance, a substantial rise in the methods of campaigner social monitoring and control, and a host of crime prevention events throughout the world.
