CCTV, commonly referred to as video surveillance, is the use of video cameras to convey a signal to a certain location and display it on a constrained number of displays. The transmission is not openly broadcasted, unlike broadcast television, albeit point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless lines may be used. Despite the fact that nearly all video cameras meet this criterion, the word is most frequently used to describe those that are employed for surveillance in locations that need additional security or ongoing monitoring (Videotelephony is seldom called “CCTV”).
