The City of Sydney has updated its 82-camera CCTV network to feature improved night vision capability, digital recording and storage.

Acting City of Sydney CEO, Garry Harding says the upgrade completely modernises the CCTV network, which is connected by fibre optics across the Sydney CBD and nearby Oxford Street, Kings Cross and Glebe.

The system helps police in the detection and investigation of a wide array of crimes including alcohol related crime, stealing and other street offences.

The new digital system is monitored live 24-hours a day and provides 106 terabytes of recording capacity, which means all 82 cameras can be recorded live at 25 frames per second and stored for up to 28 days.

"The switch to digital recording and upgraded cameras improve image quality for City camera operators, helping them identify potential incidents and assist police to respond. The system will also improve live feeds to police when incidents occur," said Mr Harding.

He said the cameras feature a more powerful zoom and low light capacity, which gives a clearer, sharper picture to assist police during investigations and prosecutions.

During the past 12 months the City of Sydney has transferred 715 incidents to police to assist with prosecutions.
A back up generator and second cabling system has also been installed to protect against accidental disruption and improvements were made to conference room facilities, the IT network and the radio and phone communications network.
