Body worn video (police equipment) Police. In 2006, the first significant deployments of body worn video at the national level were undertaken by the Police Standards Unit (PSU) as part of the Domestic Violence Enforcement Campaign (DVEC). The basic command units equipped with the head cameras recorded everything that happened during an incident from the time of arrival which led to the "preservation of good-quality first disclosure evidence from the victim". The evidence gathered was deemed especially useful in the way of supporting prosecutions if the victim was reluctant to give evidence or press charges. This led the Home Office to publish a report stating
Body worn video enforcement's use of body-worn cameras found that incidents where police used force and formal misconduct complaints decreased significantly; scholars of crime were unsure to what extent body-worn cameras played a role in the decline, but noted that the results were consistent with trends in other cities were cameras have been introduced. Howard M. Wasserman has identified several other limitations. Adopting body worn video can have unintended outcomes. In particular, increased transparency can create over-deterrence: when officers know they are being recorded, they will only do the minimum required. Another limitation is the video evidence.
