A trial program in which police will be able to record their interactions with the public on video and audio through equipment attached to their uniforms has been given the go-ahead after concerns regarding privacy were resolved last week.

Earlier this year, Fairfax Media reported the so-called uniform cams – which are already in place in the United States and other Australian states, such as New South Wales – were to be tested by police in the southern region of Melbourne, before the trial run was criticised by the police union for its potential to undermine privacy and public trust in police.

Assistant Commissioner Luke Cornelius said on Tuesday that he saw no reason for the test to not go ahead after a "series of exhaustive reviews and consultations with the Commissioner for Law Enforcement Data Security", mainly regarding privacy, were finalised last week.

He said the trial would begin today and last until March. In total, the test would cost $25,000 over the three months and involve 20 police from Frankston, and would eventually be evaluated, with public input, before being potentially enforced.

"We will be seeking feedback from members of the community ... around their perceptions and views whether or not this is an appropriate course to take," he said.
