A body camera, bodycam, body worn video (BWV), body-worn camera, or wearable camera is a wearable audio, video, or photographic recording system.

Body cameras have a range of uses and designs, of which the best-known use is as a part of policing equipment. Other uses include action cameras for social and recreational (including cycling), within commerce, in healthcare and medical use, in military use, journalism, citizen sousveillance and covert surveillance.

Nascent research on the impact of body-worn cameras in law enforcement shows mixed evidence as to the impact of cameras on the use of force by law enforcement and communities' trust in police.[1]

Designs[]

Body-worn cameras are often designed to be worn in one of three locations: on the torso, on or built into a helmet, and on or built into glasses. Some feature live streaming capabilities, GPS positioning, automatic offload to cloud storage, while others are based on local storage. Some body-worn cameras offer automatic activation of the cameras with the ability to adhere to that agency's specific body camera recording policies. The National Criminal Justice Technology Research, Test, and Evaluation Center has conducted market surveys on body-worn cameras to assist organizations in purchasing the best camera. The survey discusses device functionality, optics, audio, GPS, and several more categories. These cameras range in price from 200 dollars to 2,000 dollars.[2]

Applications[]

Law enforcement[]

Main article: Police body camera

Wearable cameras are used by police and other law enforcement organizations in countries around the world. The cameras are intended to improve interactions between officers and the public. The first generation of 'modern' police body cameras was introduced around 2005 in the United Kingdom, followed from 2014 onwards by large scale implementation in the United States, mainly to increase transparency and police accountability. Other countries have followed the trend. Early studies overwhelmingly showed positive results, but replications have led to mixed findings. Outcomes have been shown to differ depending on the local context and the guidelines regulating activation of the bodycams. Challenges include training, privacy, storage and the use of recordings further 'downstream' in the judicial system. A systematic review assessed the available evidence on the effect of body-worn cameras in law enforcement on police and citizen behavior and found that body-worn cameras may not substantially impact officer or citizen behavior and that effects on use of force and arrest activities are inconsistent and non-significant. Research suggests no clear effects of body-worn cameras in terms of citizen behavior such as calls to police and resisting arrest. [3]

Military combat[]

Body worn cameras, as well as helmet cameras are used in the military.[4] Video can either be stored locally, or streamed back to a command center or military outpost. A notable instance of this was the raid on Osama Bin Laden’s compound, where live video footage of the raid is believed to have been streamed to the White House.[5] In 2013, a British Royal Marine soldier was convicted of murder after shooting to death an unarmed and injured Afghan insurgent, contrary to the Geneva Convention. The incident had been recorded by a helmet camera whose images and sound were used in evidence at a court martial relating to the incident.[6] The helmet camera has been the focus of the Discovery Channel series Taking Fire about the 101st Airborne in the Korengal documenting their personal war footage. In 2016 "a camera recovered from the helmet of a dead fighter offers a contrasting picture of chaos and panic in a battle with Kurdish peshmerga."[7]

Firefighting[]

Firefighters use helmet cameras as a tool to assess fires and for communication and training purposes. Cameras in this occupation are often thermal cameras in order to be able to see in darkness and inside smoke-filled buildings. Augmented reality can be added to accentuate outlines of objects and people.[8]

Healthcare[]

Body worn video has been suggested and explored in parts of the medical field. Data recorded from wearable cameras can assist in medical research and limit error caused by inaccurate self-reporting of data.[9] It is speculated that under-reporting is common when conducting dietary and nutrition assessments.[10] Research suggests body worn video reduces under-reporting of intake during such assessments.[11] Cameras can for example be used as a memory prosthetic for conditions that affect the memory.[12] Body worn devices have been used to assist in clinical settings. In 2013, Google Glass was used to assist in surgery by providing a mostly hands-free way to broadcast and receive consultation from another surgeon.[13] Body cameras were provided to hospital staff by the Cardiff and Vale Health Board in Wales, United Kingdom. The cameras were issued to reduce the likelihood of violent assaults against staff. According to the manager who provides support to staff who have been attacked, the cameras – and especially the audio recording – have been vital for successful prosecutions.[14]

Privacy concerns[]

Concerns over privacy have been raised with this technology, most notably in the context of Google Glasses and policing. The advent of large-scale data collection, possibly in combination with facial recognition and other technologies capable of interpreting videos in bulk, means that all cameras, including body worn cameras, could create a means of tracking people anywhere they go. In policing, critics have warned that each police officer could become a "roving surveillance camera"[15] Police will interact with citizens during vulnerable moments,[16] such as in a hospital, or in a domestic violence situation. Concerns have also been raised that this algorithms not only infringe on privacy rights, but could also be ethnically biased.[17] The American Civil Liberties Union has suggested policies to balance citizen's rights with the desire for more transparency and accountability.[18]
