Photo-radar uses regular radar to measure your speed, and the special camera automatically takes a photo of your vehicle. The photo is then mailed to you with a speeding ticket. You do not get stopped by police at that time. It sends out a laser beam to measure the speed of your car, instead of using radar. If you are speeding, you are stopped immediately and issued a ticket.
Regular radar works by emitting a radio frequency.
It was the first type of radar used years ago, and is now used in various frequency bands like X,K, and Ka. Our Photo Fog was designed for those areas where our popular Anti-Photo radar license plate covers can not be used. Photo Fog prevents a ticket under the correct light conditions. This is what Photo Fog was designed for. It works by reflecting back the strong photo radar flash and overexposing the license plate in the picture.
