Question about SPECS

[Berger]

Specs cameras ontop of the huge towers, how far away from the cameras do they read registrations from?

Also, in a set of 4 cameras, do they measure speed between each one or just as a whole, so if you broke the limit in say the first pair you could slow for the next ones and thus end up under the limit?

Just curious as to how they work thats all.

The distances depend on the angle/height of the camera mounting as well as the lens/lenses fitted.

Search for ANPR distances in Google

Seems its around 40-50M from the cameras, thought it would be further than that with the height they are at!

Just saw them in traffic today on the M1 for roadworks and got me thinking, wasnt entirely sure where they started, slowed down when i was about that distance away from them, and then the traffic was going 10mph under the limit anyway.

Was wondering if they would pick up if people joined the SPECs controlled zone half way through ie, 2 cameras of the 4 left or not.

They seem a good way of enforcing the limit, but it seems to bunch traffic up....
