One of the new solar-powered public safety CCTV cameras installed in the ACT.

The ACT government has expanded the territory's public safety CCTV network, which police have used to investigate crime on 298 occasions since the start of 2018.

Police and Emergency Services Minister Mick Gentleman said 12 solar-powered CCTV units had been installed at crime hotspots across the ACT since June 2017 as deterrents and to support police investigations.

The new cameras are at locations including the entrances to Glebe Park in the city and the Jerrabomberra Wetlands car park in Kingston, as well as in the Tuggeranong town centre between Anketell Street and Lake Tuggeranong.

They join 72 existing public safety cameras that cover a range of locations including Canberra's central business district, GIO Stadium, Manuka Oval, Exhibition Park, the Kingston and Manuka shopping precincts, and the capital's bus stations and depots.
