SPECS (speed camera)
About SPECS cameras
SPECS cameras operate as sets of two or more cameras installed along a fixed route that can be from 75 metres (246 feet). Maximum distance was 10km with SPECS1 (SVDD) but with the event of SPECS3 became unlimited although legal requirements limit the maximum practical distance. They work by using an automatic number plate recognition (ANPR) system to record a vehicle's front number plate at each fixed camera site. As the distance is known between these sites, the average speed can be calculated by dividing this by the time taken to travel between two points. The cameras use infrared photography, allowing them to operate both day and night.
There is a popular misconception that the Home Office has approved the SPECS system for single-lane use only. According to this theory, a motorist can therefore switch lanes between cameras and claim non-approval to avoid prosecution for speeding. Indeed, the cameras can only operate in pairs, where each pair only monitors one lane of a multi lane road. So in theory, one can escape detection by changing lanes between the entry and exit cameras. In reality, two or more sets of pairs of cameras are arranged to have overlapping areas of monitoring; since the driver cannot tell which cameras are 'entry' and which are 'exit', as they look identical, they cannot tell where to change lane to escape detection. With the introduction of SPECS3-Vector cameras were able to monitor more than one lane including traffic going in different directions as long as the orientation of a pair of cameras is the same.
The system has another deficiency in that since the cameras only read the front number plate of a vehicle, speeding motorcycles escape detection because they have no front number plate to read. This issue went away with the introduction of SPECS3 which can be set up to be forward facing as well as rear facing allowing motorcyclists to be caught. A prime example of a site setup for this is the A537 Cat-and-Fiddle site.
The cameras are often painted yellow and have been given the nickname "yellow vultures".

SPECS is a speed enforcement system, which uses linked Automatic Number Plate Recognition (ANPR) cameras to monitor the average speed of traffic over a section of road, or network of roads. It has been used in the UK to control speeds on routes with a collision history and at major roadworks since achieving UK Home Office Type Approved (HOTA) in 1999.[non-primary source needed]
