There is an extensive network of more than 77,000 CCTV cameras operating across London’s transport network including 12,000 cameras across the Tube network.
However, it is not possible to give the exact number broken down by year and borough as Transport for London (TfL) does not operate a single system that records the overall numbers. This is because it is a complex picture with cameras located at many sites across the transport network such as bus garages, on the road network and in stations and car parks. Others are not tied to a particular location, for example those on buses or tube trains, or are operated by individual bus companies or concession holders on behalf of TfL.
Because of the complex nature of your request, TfL’s Assembly Relations team would be happy to meet with you to discuss this further. Please do get in touch with them if this would be helpful.
