A Microwave Detector works by setting up an invisible bubble which triggers the alarm if entered. A dual zone sensor works like two seperate sensors. The outer zone extends outside the vehicle and is usually connected to the "warn off" feature found on many alarms. The inner zone protects the interior of the vehicle. - Dual Zone Microwave Sensor for Car Alarms
