Mmm i've never left my K band on but i wouldn't have slowed down for K band anyway. I generally drive through it once a week very early in the morning. The first 2 times i either thought someone else had been flashed, as there were a couple other cars around or the camera was faulty. It wasn't like i was going much above the speed limit but it's still something.

Did your K band go off for that intersection before the new camera was put in? They also have a CCTV camera next to it, i don't know if that is new or not
