Today we show you where they are.

Most of the new cameras are still linked to the NT Police headquarters in Berrimah, but are located on highways and major intersections.

Seven CCTV units were erected late last month and are still being fine-tuned.

The unheralded roll-out is funded by the Department of Infrastructure, Planning and Logistics.

Katherine already has a number of cameras, chiefly along Katherine Terrace and First Street, keeping an unseen eye out for anti-social behaviour.

A DIPL spokeswoman said there was an extra seven cameras added to the secure police network.

The cameras are covering the School Bus Interchange on Chambers Drive, Victoria Highway/Railway Terrace area and the Bicentennial Road/Stuart Highway area.

All poles and cameras were installed last week with some final testing and commissioning  to  occur over coming weeks.

Three of the seven are located at the intersection of the Stuart Highway and Bicentennial Road – home to Whitehouse Furnishers and a new Puma Energy service statiion.

The project was funded as part of the Minor New Works Stimulus package. 

The spokeswoman said other works in Katherine included the upgrade and extension of the Dual Use Path on Victoria Highway, the resurface of a section of cycle track from Katherine to Tindal and a new school bus shelter on Victoria Highway.

The department last week awarded a contract to replace and upgrade lighting to LED technology in Mataranka and Katherine.

Works in Mataranka are scheduled to start in the next few weeks.

In Katherine, the street light upgrade mainly applies to Katherine Terrace, up Katherine Town Council completed upgrades in most other areas of town over the past year.
