CCTV

CCTV was a specialized 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 would use the CCTV cameras to watch people for unprofessional reasons, such as Captain Jack Harkness watching Gwen Cooper kiss her fiancé Rhys Williams. (TV: Meat)

The cameras have occasionally been externally shut down, such as when Weevils were being kidnapped. (TV: Combat)
