High Definition closed camera television is a modern security surveillance system. It applies the digital video technology by transmitting digital video over point. It is a directed to coaxial cable links for video surveillance applications. SMPTE HD-SD1 protocol is used in transmitting 720P AND 1080P over at least 100 m of RG59 cable. Many homes, streets, and premises are fitted with HD CCTV technology to boost security.
Origin of CCTV Technology
Earliest documents show evidence of CCTV usage in Germany. In 1942, a German engineer Walter Bruch designed a surveillance system to monitor V-2 rockets. 1n 1949, the system was launched and developed on a commercial basis and promoted by an American government contractor. These early surveillance cameras, however, could only support live monitoring. They lacked components for recording footage.
They later introduced reel to reel recording systems by using magnetic tapes to store data. In the 1970s, a great development was made by adding video cassette recordings VCRs. Dramatically this changed how cameras were used. People could no longer monitor the cameras live but could allow them to run then review the recorded information. Also, the introduction of multiplexing technology and digital video recorders DVRs transformed CCTV technology. Multiplexing allows signals from different cameras to be viewed on one screen. DVRS replaced magnetic tapes and VCRs.
