CCTV or Closed Circuit Television refers to a visible or covert video system intended for only a limited number of viewers. In CCTV the picture is viewed or recorded, but not broadcast. It was initially developed as a means of security for banks and casinos; however, today it has been developed to the point where it is simple and inexpensive enough to be used in every business premises and Home Security Systems, for everyday surveillance.
 
More specifically, CCTV is a television transmission system in which live or prerecorded signals are sent over a closed loop to a finite and predetermined group of receivers.
