Body worn cameras with audio have opened up a lot of chances and potential advantages for law enforcement agencies that weren’t previously possible. Top advantages include:

Public trust in local and national policing is boosted, and there are fewer complaints and allegations against police officers.
a decrease in the expense of criminal justice because of an increase in early guilty pleas
decreasing the severity of antisocial behavior
a decrease in the frequency of attacks on police officers
the capacity to use body-worn cameras in locations not serviced by other types of CCTV
Officer skill improvement through the evaluation of incident performance
less time spent on paperwork by officers

Several police departments have recently made public in-depth reports on their experiences with wearing body cameras. These papers’ figures, which show that the increasing use of body worn cameras is improving modern policing, are as follows:

33% fewer complaints were made, according to the Metropolitan Police (UK)
According to Cambridge University, police officers who use body cameras get 93% fewer complaints from the public.
Officers wearing cameras have reduced use-of-force occurrences by 59% in Rialto, California (USA)
Early guilty pleas are up 39%, according to Police Scotland (UK)

In addition to the cameras’ benefits for the organization, wearing body cameras has a good impact on officers themselves. According to 93% of officers, wearing body cameras makes it easier to acquire evidence, and 80% of officers think wearing body cameras should be required.

Because significant events may be missed if a camera has a relatively narrow field of view, viewing angle, also known as field of view, is crucial. The average person’s field of vision is about 114 degrees, not including peripheral vision, but since the majority of body-worn cameras don’t spin with you, a wider field of view is usually preferable.

Attachment. Consider what you’ll be wearing (maybe a uniform?) and where you can connect the camera before choosing how to wear it.

Operating time, or battery life, is crucial. Also keep in mind that features like IR night modes can burn battery a little more quickly, so don’t cut this too thin.

Storage. Your demands will determine whether to utilize simple built-in memory for looped recording or removable memory cards, which are helpful for easy copying to a computer. It is also possible to record in a loop to removable cards. In either scenario, you should be careful to transfer and duplicate any key events before using the camera again in case the data is lost.
