Were talking about 2 different things. Ok you know when you go to the store and the k band sensor detects you are there and opens the door?
Ok well they have these at intersections and most people don't even know what they are for. If there is not a loop or apron in the ground to detect a car there they will but up a sensor like a dor sensor only it looks like what you see in the video. Most if not all are X band. But for some reason these were k band and they were at a crosswalk. Not even facing traffic so it's not for traffic.
