Body-worn video cameras for police are launching in Wandsworth today (July 24).

The roll out of the recording devices to more than 22,000 Met Police officers in London began in October last year following trials that began in 2014.

The Met said the cameras bring about speedier justice for victims, which proved particularly successful in domestic abuse cases where there has been an increase in earlier guilty pleas from offenders who know their actions have been recorded.

Chief Inspector Dale Anderton, Wandworth's Body Worn Video lead, said: "We are very much looking forward to all of our frontline officers having the ability to record live video.

"This will further ensure transparency in all our actions, and greatly improve the quality of evidence available to investigators and the courts.

"This in turn means that the police and our local partners will be able to make Wandsworth even safer."

The cameras are worn attached to the officer's uniform and do not permanently record.

This ensures interactions with the public are not unnecessarily impeded.

Members of the public are told as soon as practical that they are being recorded.

When the camera is recording, it is highly visible with a flashing red circle in the centre of the camera and a frequent beeping noise when it's activated.
