CCTV stands for Closed Circuit TV. CCTV uses one or more video cameras to transmit video images and sometimes audio images to a monitor, set of monitors or video recorder. The difference between CCTV and standard TV is that standard TV openly broadcasts signals to the public.

CCTV is not openly transmitted to the public. CCTV uses either wireless transmission or a wired transmission to send the broadcast from the video cameras to the monitor(s) or recording device. Most CCTV systems are used for surveillance which can include security monitoring, spying or for safety monitoring purposes.

A video monitoring system is more commonly known as Closed Circuit Television Systems (CCTV). A CCTV system is an on premises system consisting of a television camera, video monitor, and a transmission medium (Cable, fiber or wireless) connecting the two. It is used to monitor the premises. Probably the most widely known use of CCTV is in security systems and such applications as retail shops, banks, government establishments, etc.
