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

Surveillance of the public using CCTV is common in many areas nearly the world. In recent years, the use of body worn video cameras has been introduced as a supplementary form of surveillance, often used in con enforcement, behind cameras located upon a police officer's chest or head. Video surveillance has generated significant debate practically balancing its use behind individuals' right to privacy even taking into account in public.

In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example in the same way as the environment is not normal for humans. CCTV systems may show for all time or forlorn as required to monitor a particular event. A more ahead of its time form of CCTV, using digital video recorders (DVRs), provides recording for possibly many years, bearing in mind a variety of atmosphere and produce a result options and additional features (such as interest detection and email alerts). More recently, decentralized IP cameras, perhaps equipped once megapixel sensors, keep recording directly to network-attached storage devices, or internal flash for unconditionally stand-alone operation.

By one estimate, there will be approximately 1 billion surveillance cameras in-use worldwide by 2021. about 65% of these cameras are installed in Asia. The accrual of CCTV has been slowing in recent years. The deployment of this technology has facilitated a significant deposit in let in surveillance, a substantial rise in the methods of radical social monitoring and control, and a host of crime prevention events throughout the world.
