CCTV, Closed Circuit TeleVision, is a TV system that does not broadcast TV signals to public but transmits them over to limited monitor(s). CCTV system usually utilizes CCD video cameras (to produce the video), cable or wireless transmitters/receivers or Internet (to transmit the video), and monitors (to see the video). CCTV system is not only applied to the security and surveillance purpose but also to the other fields like laboratory in schools or in private companies, even to production lines in factories. As the application of CCTV system increased, the CCTV industry has developed variety of CCTV equipment like Time Lapse VCRs, combiners, infrared illuminators, Pan/Tilt, etc. The most recent development is web camera server which uses the Internet for remote surveillance. |
