More than 4,000 pieces of video evidence have been submitted to the Crown Prosecution Service over the last nine months by Cumbria Police.
The force says this is due to the introduction of body-worn cameras that were rolled out last year.
The discreet cameras, which are worn on the front of an officers uniform, can record both video and sound.
Each piece of footage captured on duty can be used as evidence in investigations, which in turn can lessen a police officer's time spent in court.
There are opponents to the increasing use of bodycams. Big Brother Watch have concerns on the impact it may have on the privacy of those filmed and think more time should be spent regulating their use.
