CCTV

A CCTV network, known colloquially as simply CCTV, was a specialised camera system used by Torchwood Three to track people down. It gave them access to all the surveillance cameras in Cardiff. (TV: Day One) The camera images came up on the computer screens stationed all around the base. (TV: Day One, Meat, et al)

As well as around the city, the CCTV cameras were also posted inside of the Torchwood base itself, occasionally being used to monitor prisoners (TV: Day One).

Occasionally, members of the Torchwood team used the CCTV cameras to watch people for personal reasons, such as when Captain Jack Harkness watched Gwen Cooper kiss her fiancé Rhys Williams. (TV: Meat)

The cameras were sometimes shut down, such as when Weevils were being kidnapped. (TV: Combat)
