A Microwave Detector works by setting up an invisible bubble which triggers the alarm if entered.

The dual stage microwave detector effectively works like two seperate sensors. The first "stage" or "zone" is set to be more sensitive and is adjusted to extend outside the vehicle and is usually connected to the "warn off" feature found on many alarms, a seperate buzzer or one of our Voice Warning Modules. The second stage is connected to the alarms main sensor input and is then set to protect the interior of the car, triggering the the full alarm if it is activated.
