They did a test a while back on TV and tried the various sprays, filters, covers etc.. None of them worked. The camera takes multiple pictures starting before the flash and ending after it. Any plate that is not clearly visible due concealment efforts is manipulated through filters, black/white, negative image etc. so they were able to clearly ID the plate everytime. Any effort to conceal the plate in CA is illegal and a moving violation so it will cost you a point on the driving record. My friend tried a cover type deal and not only got a ticket at the red light camera the pictures clearly showed the cover so they wrote him up for that as well. $450 dollars later he lost his case at court.
