Question

How long does TfL keep Bus and Underground CCTV footage and what checks are in place to ensure the operation of equipment? There was a youth gang mass robbery on the 188 bus in Rotherhithe at Canada Water on 8th December. TfL have been as yet unable to produce the footage as requested by the local Police (public feeling is running extremely high on this). Are the victims of this crime to be let down by TfL buses CCTV?

Typically retention timescales for on-bus CCTV footage range between five and ten days, dependant on: · Refresh or compression rates for recorded images that the on-bus CCTV system is programmed to produce. · Hard drive memory capacity · The amount of time the vehicle is in operation over a period of time. Regular on-bus CCTV camera checks are in place at all bus operating companies. They vary from every week to every four weeks and all checks are audited. A small number of automatic download on-bus CCTV systems have their own 'built-in' health check. CCTV cameras are also independently checked on a monthly basis by the Freight Transport Association (FTA) on behalf of TfL. For 2006 the sample check of vehicles from bus garages in London, showed the on-bus camera failure rate was 3.5%. TfL is actively working to drive this level even lower.CCTV footage from London Underground stations is retained for 14 days from stations and for 72 hours from trains. This is due to the limitations of storage capacity. Analogue CCTV systems on stations and trains are checked daily when the tapes are changed. Digital CCTV systems on stations and trains are checked every three months and an alarm is activated if they malfunction.With regards to the incident in Rotherhithe on the 8th December 2006, I have asked TfL to brief you on the incident.
