Tell that the the 250+ people that got done in Brum a few months ago.
The police used cameras hidden in traffic lights.
You may even have noticed the extra "sensors" appearing on top of some
lights if you weren't so thick.

Are you sure you are not getting confused with the fact that many red
light cameras also now measure speed? They are often described as
traffic light speed cameras, but they are a separate box, not hidden in
the traffic lights.

The detectors you see on the lights themselves are most probably traffic
detectors for the lights themselves. They have several advantages over
inductive loops buried in the road.

They are cameras, the normal traffic sensors are also present.

How about posting a picture, so we know what to look for? You might send
a copy to these people as well, as there is nothing like that on their
web site:

The police have covert cameras as well, they are hard to spot.

Around here, they put them in a large van with a big camera logo on it
and still get lots of customers.
