Closed-circuit television (CCTV) is also 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, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, stores, and other areas where security is needed.
Public surveillance using CCTV is quite common around the world. Video surveillance has generated significant debate about balancing its use with individuals’ right to privacy even when in public.
