SEVEN different types of speed cameras are out there looking to catch you out.
And several of them will register your details for a fine, points or speeding course without even flashing.
Here is a high-speed rundown of all the different cameras, how they work, where they are usually placed and whether they flash.
Gatso and PEEK
These are the classic square boxes and sit on your side of the road.
The rear-facing cameras measure speed by using the white lines on the road once you’ve driven past.
It takes two photos and works out how quick it took you to travel the distance between the two points, using the lines as markers.
They flash but won’t dazzle drivers because they face the other way.
This is a thin and narrow yellow cam.
Unlike Gatso and PEEk cameras, they are front-facing so the photos it takes can also show who is driving.
The cameras rely on infra-red tech and measures speed using sensors in the road as well as the white lines.
This is an abbreviation of Highway Agency Digital Enforcement Camera System.
These cameras are usually mounted on a bar on motorway gantries or on poles at the side of the road.
The small and grey devises can be difficult to spot and there is no visible flash. They can capture up to five lanes at a time.
SPECS and VECTOR
These are average speed cameras. There will be at least two put on gantries at a minimum of 200 metres apart on a road.
They will track your average speed across the two points, using infra-red technology. They do not flash.
The shortest speed check is half a mile in Cornwall while the longest is 99 miles on the A9 in Scotland.
These average speed cameras are often found in town and village centres, as well as dual carriageways. No flash.
Fitting into a network of up to 1,000 separate cameras linked together, they can monitor an area for 24 一天几个小时.
They also measure the average between fixed points and catch drivers going both directions. No flash.
Redflex have cameras checking for speeding in up to six motorway lanes, while its red cameras monitor junctions for drivers jumping the lights.
Neither of them flash.
