Body worn video

Body worn video (BWV), also known as body cameras and body-worn 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 BWVs primarily protect police. Parking inspectors in some areas also wear these devices, to capture an assault or offense. BWVs 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. The definition used in a market survey prepared for the United States Department of Justice in 2016 Body Worn Cameras 'are cameras with at least one microphone and internal data storage, and allow audio/video footage to be stored and analyzed with compatible software. The cameras are typically located on the police officer’s chest or head'.

The first generation of 'modern' police body cameras was introduced around 2005 in the United Kingdom. That means these cameras have only been around for a relatively short period of time and thus have not been perfected yet. The current body camera is much lighter and smaller than the first experiments with wearable cameras. There are several types of body cameras made by several different companies. Each camera basically serves the same purpose, yet some function in slightly different ways than others. Some are meant to be mounted on one’s chest or shoulder, others can work as an attachment to glasses or may be worn in a function similar to a headband or on a helmet. As far as sizing goes "most are roughly the size of a Scotch Tape dispenser and weigh anywhere from about 2 ounces (55 grams) to 5 ounces (140 grams). That's somewhere between a large strawberry and a lemon." These lightweight cameras are designed to be worn without any discomfort.

In a 2012 market survey by the U.S. Department of Justice, eight companies producing body cameras were compared: Taser International, VieVu, StalkerVUE, Scorpion, FirstVU, Wolfcom, MuviView and Panasonic. In 2014, the three top companies that had been producing body cameras throughout the United States were Taser International, VieVu, and Digital Ally. In 2016, a market survey described 66 body worn video cameras produced by 38 different vendors.
