CCTV Security Camera

Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point wireless links.


Today a lot of people choose wireless security cameras for home surveillance. They don’t require video cable for transmission, just a power cable, and they are very easy and inexpensive. The modern cameras use digital technology that allows for better audio and video, and a secure and interference-free signal.


Industrial processes that take place under conditions dangerous for humans are today often supervised by CCTV. These are mainly processes in the chemical industry, the interior of reactors or facilities for manufacture of nuclear fuel.
