Camera Types

Here you can find a list of cameras that we use across Derbyshire.


These cameras, in yellow housings, use radar technology to detect the speed of passing vehicles. The camera is activated when a vehicle crosses the radar beam at an excessive speed.


The camera will capture the rear of the vehicle and will capture two photographs 0.5 seconds apart. These two images assist in verifying the speed detected by using the white lines painted on the surface of the road.



These cameras, also in yellow housings, use sensors embedded in the road to measure the speed of oncoming vehicles and have the facility to photograph the front or rear of vehicles.


Operators again perform a secondary check on photographs using marker lines to verify speeds.


Mobile Cameras

Four mobile safety camera vans, an enforcement motorcycle and a CREST van operate at over 800 locations across Derbyshire. The Home Office Approved cameras are operated through the rear or side windows of the safety camera vans. There is also the option to utilise a tripod at the roadside.


All the cameras use a laser device to measure the speed of vehicles travelling towards or away from the camera. The vans are fully liveried with the 'CREST' markings.

SPECS 3 Average Cameras

An average speed camera continuously captures images of vehicles as they pass through its field of view.


Number plates are read using Automatic Number Plate Recognition (ANPR) and when the same vehicle is recorded by any other camera connected to the system, the average speed of the vehicle is calculated over the known baseline distance.


Cameras can be installed in front or rear-facing orientation and violations can be recorded between multiple locations and multiple lanes within the system.

HADECS 3 M1 Cameras

These cameras known as HADECS (Highways Agency Digital Enforcement Camera System), are fitted onto gantries. They are used by Derbyshire Police on the M1 within Derbyshire.


Another camera before the gantry monitors the electronic signs which show the speed limits. When the speed limit changes or a RED X is introduced, the cameras trigger when they detect a vehicle committing an offence.


The HADECS 3 cameras use a dual radar for speed detection across all lanes of the motorway. In addition, HADECS 3 cameras can identify which lane and which vehicle committed the speeding offence.
