Has any one heard of these devices VF2 Photo Jammer
Blurb:
Using a sophisticated sensor the VF2 immediately detect the police camera flash, and in that instant flashes the license plate with a powerful burst of white light. This downward flash across the plate instantly exposes your license plate with a powerful protective glow, so that the enforcement camera can not image the license plate number.
do they really work??
any help appreciated.
