Red-light/speed cameras - how they work

The red-light/speed safety cameras are located at traffic light-controlled intersections and photograph motorists who;

  • contravene red traffic lights and

  • speed through the intersection at any phase of the lights.

The cameras capture data including date, time, location, offence and lane.

Red-light incidents are triggered when a vehicle is detected moving over the looped sensor or wired detection of light phases. Once the light phase has changed to red, the video is used to confirm the vehicle continued through the intersection.

Speed is detected using in-road sensors and or tracking radar. 

  • Road sensors are at a fixed distance apart and measure the time it takes a vehicle to travel between each sensor. 

  • The tracking radar method, compares the data from both the radar sensors after an incident is recorded.

If the data shows that a vehicle's speed is greater than the posted speed limit, a photograph and video of the vehicle is captured. The captured images and video are sent electronically to the infringement processing system within minutes of the incident occurring.

Fixed Site (and Mobile) Speed Safety Cameras

Fixed site (and mobile) speed safety cameras use laser technology to track and detect vehicle speed. They can be operated on a tripod in a vehicle or trailer or in a road-side cabinet.

They are able to track multiple vehicles across multiple lanes simultaneously. 

Where vehicles are identified exceeding the speed limit a picture is taken and the speed data is recorded.
