Can cars travelling in the opposite direction set off speed cameras?

I keep getting flashed by speed cameras on the same stretch of road when I know I am under the limit. Could something else, such as cars going in the opposite direction, be setting them off? I've travelled up and down the A68 in different cars over the years and not experienced this before.

I don't know. Kids used to have a game called 'flash can'. They'd get a baked bean can, strip the paper off, push a knotted rope through the bottom and swing it in front of the camera with sufficient speed to trigger a flash. So all kinds of spurious things can set them off.
