CCTV refers to Closed Circuit Television, which is a form of video-based surveillance. It is characterised by a singular camera, or a network of cameras, which transmit a signal into one specific point, where it can be reviewed by the operative.

As the coverage and the ubiquity of CCTV networks continue to spread, it’s good to be fully aware of what the technology can do and how CCTV works.
