What is the difference between photo-radar, laser, and regular radar?
A. Yes, very different. 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. “Laser” refers to being targeted by a laser gun operated by a police officer. 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. Newer radar detectors detect all these frequencies (see paragraph about why radar detectors do not work for Ka photo radar).
