In Canada we have a highway called 407 where you need a transponder to record your trip or the camera takes a picture of your plate and you are billed a camera fee plus your trip fee. Is there anyway to beat this camera? I have seen some sprays that apparently make your plate invisible to them, but I think that only works on red light camera which uses a flash. I have also seen plate covers that distort your plate at an angle. I'm looking for a sure thing though that's undetectable.
