Body worn video (BWV), also known as body cameras, is a video recording system that is typically utilized by law enforcement to record their interactions with the public or gather video evidence at crime scenes, and has been known to increase both officer and citizen accountability. Although arguments have been made that BWC's primarily protect police. BWCs are notable because their placement, often on the front of a shirt, provides for first-person perspective and a more complete chain of evidence. BWV is a form of closed-circuit television.
