Speed Camera Enforcement System (SPECS)
The SPECS average speed camera systems utilises state of the art automatic average speed digital technology, which not only calculates and records the average speed over a given set distance, but also uses an Automatic Number Plate Reading (ANPR) video system. That set distance could be between two cameras, creating a Speed Control Zone, or between several sets to form a Speed Control Network. In addition, the cameras are each fitted with infra red illuminators so they can operate at night or at times of poor daylight. At present, they are most commonly found on dual carriageways and motorways, as they are able to monitor up to four lanes of traffic at any one time. There are some SPECS systems in place on single carriageway routes too, such as the A628 route in South Yorkshire. The cameras themselves are usually found on gantries above the road (as in the picture below), either positioned at the roadside, or in the central reservation. This allows them to maximise their capture rate - they can capture three vehicle images per second. As a result, the cameras have earned the nickname of "yellow vultures". The only problem is that they are only approved for measuring speed in one lane - so if you're travelling down a dual carriageway and change lanes half way between the cameras, Home Office regulations mean that you cannot be prosecuted if you exceed the speed limit.
How the System Works
Here, the ANPR system matches up the vehicle's corresponding images, and using the date and time stamp carried with each image, the system calculates the vehicle's average speed. If the vehicle is recorded as exceeding the speed limit, the cabinet automatically generates a Violation Record. This record includes a black and white image of the registration plate, a colour image of the vehicle, the date and time, location and average speed between the two cameras. The records are then stored on a large capacity storage drive held within the enforcement cabinet until downloaded - and the penalty notice is then issued.

Permanent SPECS Locations
NSL denotes that the National Speed Limit applies on that road. Location and speed information from Speed Cameras UK and Speed Check Services.
Penalties and Points At present, any driver prosecuted in the UK following being caught by a SPECS system can result in a minimum of three penalty points and a £60 fine. However the fine amount may be increased in the future as it is currently under review by the government. |

As
the vehicle passes each camera, its registration number is read,
photographed and digitally recorded. The time the vehicle takes to pass
between each pair of cameras is then recorded, where the data is then
transferred to an enforcement cabinet.
