Looks like a sensor, possibly type used at lights with bus prioroty. Traffic light cameras usually look similar to speed cameras and take two timed photographs to show light going red and time gap until line is crossed.

If you waited 10mins the sensor is faulty or perhaps you were wrongly positioned.

This one is near home and controls alternate one way traffic over a narrow bridge on a blind bend:

It won't change until you go right up to the stop line. Vehicles are then detected by the wiring in the road.

Not sure if this is a bus lane camera near where I live (this is in Cambridge and does have 'bus lane camera' signs twice in the preceeding 200m of road)

Whatever it is is on the LH pole of the large sign, at the top.

Hi, I know where this is and I went through one nearby on red by accident can you tell me what happened? Really worried. So you know what they are for? Apparently they're either thermal sensors for bicycles or a camera that can catch you.

By accident !!! Lucky girl. Concrete
