    CCTV stands for Closed Circuit Television which is a method of transfer of video signals from camera to one or more display screens. Almost any camera suffices this property and thus be called as CCTV but only few that are used for surveillance and that are used for distance transmission are named as CCTV cameras.

    These cameras differ from others in the transmission of video signals to predetermined display screens whereas others generally broadcast the video signals.

    These CCTV cameras are used along with Digital video recorders (DVR) to store the video recorded and see them whenever required. This way we can prevent crime and control it. Also these play a very vital role in control mechanisms of machinery in industries.
