NEW HAVEN, Conn. (AP) — Police officers in a Connecticut city will soon be wearing body cameras for the first time.

The New Haven Board of Police Commissioners approved body camera use in a unanimous vote Tuesday. Authorities say the police officers will start wearing them after training begins on Nov. 1.

The police department received a $700,000 grant to purchase more than 800 cameras. Each officer will be outfitted with a "hot" camera for use in the field and a "cold" camera that will be charging at the police station.

Chief Anthony Campbell previously said video cannot be deleted or altered once it's been shot.

Police Sgt. Rose Dell tells WVIT-TV witnesses or victims can request officers to turn the camera off.
