Following a Freedom of Information request to 45 different UK police forces, Auto Express has found the speed camera tolerances for forces in different parts of the country.
The majority of police forces stick to the guidelines issued by the Association of Chief Police Officers which suggests that cameras should only activate when a driver is breaking the speed limit by 10 per cent plus 2mph.
This ruling allows for a top speed of 79mph on motorways and 35mph in 30mph zones and in applies to both fixed and average speed cameras. There are a couple of police forces who allow for extra leniancy, with the Metropolitan Police and Lancashire Police using 1o per cent plus 3mph. Since some high-speed cameras are capable of recording bursts of up to GB of video in just a few seconds, transfer speeds from the camera's temporary RAM into permanent storage are almost as important as the medium itself.
Typically, all high-speed cameras can be connected to a computer via Ethernet and can offload the video that way, but the transfer rate may be limited. Because of this, faster portable offload options are usually preferred. Several portable transfer options exist on the market, but currently none are ideal. The faster options are quite expensive and sacrifice image bit depth to offload the video quickly, while the slower options are more cost-effective but…well…slower.
High-speed cameras capture thousands of individual photographs in every second. These images are captured at perfectly even time intervals, but those intervals are determined by the camera. If two cameras are in use simultaneously, for example in a 3-D experiment, they will inevitably capture their images at slightly different times.
For this reason, most cameras can lock the timing of image capture to an external reference, called a sync source.
Some cameras are more flexible than others, providing different modes of use, the ability to follow varying speeds of external syncs, and even the ability to be a sync source for other cameras. High-speed cameras are complex and expensive scientific devices requiring periodic updates, troubleshooting and support.
