I notice the cameras showing up at stop lights. But I have not heard of speed traps cameras.

Maybe some LEO on this website can clarify, but a few years ago a local municipality set up a camera on one of the trailers that record your speed. The local police started sending out citations to those who were recorded speeding. I can't recall the reason, but the citations were thrown out by the district court.

I do know in Manchester and Nashua, the police been sending out citations for Stop signal/sign violations recorded on camera.
