Almost seven years after a critical report recommended a register of all government and private closed-circuit television cameras operating in the territory, no such lists exist.

A range of federal and ACT government agencies maintain their own networks but the systems are not linked, limiting their use in preventing crime.

At the time, former chief minister Jon Stanhope said recommendations from the government-commissioned report, made after the London bombings, would be acted on as a matter of urgency.

The report found there was no accurate list of closed-circuit television cameras run by the federal and territory governments through which police could quickly and easily identify whether a particular area was subject to CCTV surveillance. That capacity was invaluable during the London bombings investigation, which used the city's sophisticated network of cameras to trace suspects.

Chief Minister Katy Gallagher's office referred all questions about the report to Attorney-General Simon Corbell. A spokesman from Mr Corbell's office referred the matter to the Justice and Community Safety Directorate.

''A register is not feasible from a practical point of view, due to the very large number of privately owned and operated cameras across the ACT. The register would need to be continually updated to maintain its integrity, which would be resource intensive,'' the spokeswoman said.

But one of Canberra's largest organisations has worked with businesses and government agencies at Brindabella Park business centre and Majura to create a network of 315 cameras.

Managing director of Canberra Airport Stephen Byron said 260 cameras were owned by the airport, and airport police were able to view images from 55 privately operated or federal government cameras when necessary, effectively increasing the capacity of the network by 20 per cent.

''The COAG framework was about not mapping our own cameras but also any other cameras that are with any other organisations, government and private, on the airport site,'' Mr Byron said.

''The bulk of it was done within 12 months of that report but it's an ongoing task so we're always updating the maps.''

Footage recorded at the airport is kept for 30 days, in line with the COAG recommendations. He said police used footage from cameras not owned by the airport regularly.

''It's a sophisticated system and it allows people to be tracked, not just doing one thing but followed as they move through the airport. It takes five minutes to find the footage and look at it.''

To try to find out how many cameras are watching Canberrans, The Canberra Sunday Times requested numbers and maps from government agencies. Each request had to be made separately as no complete list exists.

ACT Health said 225 cameras are run by the department at five locations with 200 located at Canberra Hospital. Calvary Hospital has 28 cameras.

JACS co-ordinates 72 cameras across Canberra. TAMS has about 2000 cameras on Action buses and a further 393 cameras across the ACT at waste facilities, cemeteries, national parks, Canberra Connect shops fronts, libraries and bus stops.

Camera figures at the Bimberi Youth Justice Centre and Alexander Maconochie Centre were not disclosed on security grounds.
