New cameras set to be added to vests of NSW frontline police will be good for both cops and the community, its supporters say.

Victims of crime are likely to get justice quicker with NSW frontline police being outfitted with body cameras, the Police Association says.

The NSW government announced on Sunday that it will be spending $4 million over two years to roll-out the body worn video (BWV) cameras for frontline police.

The cameras will be attached to the vest of the officers and are expected to be housed inside the radio unit.

Police Association President, Scott Weber, said the cameras will be good for cops and the community.

“Video captures events in a way that can’t be represented on paper in the same detail and it has been shown the presence of this type of video can often defuse potentially violent situations without the need for force to be used,” he said in a statement.

“It will also show police dealing with difficult and dangerous situations every day and it will also provide clearer evidence when it’s been alleged that police got things wrong. That has to be in both our own and the community’s interest.”

The cameras have already been trialled by the Public Order and Riot Squad, South West Metro Regional Enforcement Squad, Brisbane Water Local Area Command and the Northern Sector of the Police Transport Command.

These showed a reduction in frivolous claims against police and changes in the behaviour of potential offenders because of being recorded.

“The cameras would likely bring swifter justice for victims, especially in domestic abuse cases, as people were more likely to plead guilty when they know the incident has been filmed.”

Officers attached to the Public Order and Riot Squad, Police Transport Command and other highly mobile frontline officers will be given priority for the cameras.
