CCTV

The CCTV cameras are used by the team of Torchwood Three to people down. It seems that this only works in Cardiff, but seeming as there were Torchwood branches in London, Glasgow and presumably somewhere else (the location of Torchwood Four was never mentioned as it was "missing" TV : Everything Changes). Occasionally, members of the Torchwood team use the CCTV cameras to watch people for unknown reasons, like Captain Jack Harkness watching Gwen Cooper kiss her fiancé Rhys Williams TV : Meat.
