Closed-circuit television (CCTV), 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 multi point (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. Though Video
telephony is seldom called \'CCTV\' one exception is the use of
video in distance education, where it is an important tool.
Surveillance of the public using CCTV is common in many areas
around the world. In recent years, the use of body worn video
cameras has been introduced as a new form of surveillance, often
used in law enforcement, with cameras located on a police
officer\'s chest or head.Video surveillance has generated
significant debate about balancing its use with individuals\' right
to privacy even when in public.
