UK Police Begins Deployment of 22,000 Police Body Cameras (thestack.com)
An anonymous reader writes: London's Metropolitan Police Service has begun a roll-out of 22,000 Body Worn Video (BWV) cameras to officers over the city's 32 boroughs after ten years of country-wide trials. The device, which records video only when the officer decides, has a 130-degree field of view and a 30-second buffer which permits police to begin recording even after an event has started. The makers of the camera also provide an Android/iOS app which can allow a remote viewer to connect to an officer's camera, effectively turning police operatives into walking CCTVs. Academic research has suggested that use of BWV cams can reduce complaints against officers by 93%, and the Met contends that the new technology, whose cloud-based systems erases unwanted videos after 31 days, is particularly effective in domestic violence cases.
