What is CCTV?

Using video cameras for video signal transmission to a closed group of people, using limited set of display devices is known as CCTV.

In general video signal transmission is linked with broadcasting. TV channels that are aired can be watched by anyone. They can be classified as open communication.

Whereas, in a CCTV its available only to a set of people with privileges to access the system. Not everyone can monitor the CCTV output like we are watching satellite channels like Sun TV , Jaya TV, etc.
