While I was in London for the holidays, I noticed that some PSAs on the DLR were now wearing body cameras. I also noticed a sign in the Bank DLR corridor notifying that body cameras were being slowly rolled out. Is there any reason for this? DLR stock are already fitted with CCTV cameras in every car, so maybe they don't cover the whole interior of the train? I know that PSAs are tasked with revenue protection so I can sort of understand why they may be put in dangerous situations sometimes although I've never seen a passenger become too irate.
Whilst platform/train CCTV can be good at showing which person did what to whom and when, it's not very good at identifying people due to the angles the images are captured from. Body-worn cameras can capture a more conventional view of a person which will assist rapid identification.
Hmm food for thought, although perhaps its better to have camera glasses. the issue here however is that I need glasses for vision correction and generally glasses which have built-in cameras tend to only have plain glass lenses.
