Sitting in the rear car of a westbound Central Line train I noticed at
Bethnal Green there is a door inscribed 'Playback Room'.
What is this room used for, playing back what?
At a guess, playing back CCTV footage.
http://www.metsystems.co.uk/about.php mentions that Metsystems have
worked with BTP on specifying playback facilities "used at most stations
and control centres" in order to comply with criminal evidencing
standards.
