Special camera and computer technology combine to photograph the back of your vehicle as you drive by, and record your speed at that exact second. Based on the results - a ticket is then issued to the owner of the vehicle. Conventional radar detectors are ineffective due to kA radar's wide operating bandwidth. Even if you do detect the beam, its too late.

A 5-minute installation is all that is required.
