Gatso Meter Speed Camera, Victoria Avenue, Cambridge, UK.

The yellow front surface is shows a spotted pattern from the high reflectivity glass beads (possibly 3M reflective sheeting).

Description

Originally from the UK Speed Cameras web site:

"There are over 4,000 fixed Gatso's speed cameras currently in use by police forces and local authorities across the UK, accounting for 90% of all fixed cameras. The Gatso, which uses radar technology, is used for fixed speed cameras, in-car mobile units, on tripods, and can even be used from moving vehicles.
Fixed Gatso speed cameras are rear-facing. This is so the cameras "flash" does not blind oncoming motorists. Unfortunately, this also means the cameras are not always viewable until the last second (as pictured above). Empty units are well known to flash at oncoming traffic. The cost of installing a Gatso camera is approximately £20,000, but can cost as much as £40,000 if located in a rural location, as the system requires a 240v power supply.
The fixed Gatso camera has the ability to take up to 400 pictures. Cameras that are located in busy areas or are particularly hidden, often only last a few hours before the film runs out, soon recouping the £20,000-£40,000 price tag.
Gatso's can also identify between cars/vans and HGV's separately. For example, if the speed limit was 60 mph for cars/vans and 40 mph for HGV's the camera will enforce the two separate limits."
