CCTV

CCTV (Closed-Circuit Television) is a means of surveillance by video camera. In Britain, CCTV cameras are installed in public places with the aim to prevent crime or make the identification and persecution of offenders easier. The use of CCTV started in the 1960s, but was limited to temporarily installed cameras then. By the late 1990s, under PM Tony Blair, spending on CCTV had largely increased, and stationary cameras been installed.
