Last year, the police in the city of Leicester tested the practical use of a body CCTV camera. It proved to be successful for the police, so they are now rolling out the cameras to all police across the United Kingdom.

The cameras, which have in-built night vision, have already proved to be invaluable in a number of situations faced by the police, including dealing with domestic violence incidents and identifying offenders in large groups.

Police wear the cameras on the front of their stab vests and after attending an incident download the footage captured onto a computer where if needs be it can be transferred onto a DVD to be presented as evidence in court.

The technology has an advantage over pole-mounted CCTV cameras as it allows officers to film an incident at street level, as they see it, the force also believes the cameras will deter troublemakers from squaring up to officers or making false allegations against them.
