Description

Microwave sensors are great for convertible vehicles as the alarm can be armed with the top down. They are also good for situations where car windows are left open while the alarm is armed.

A microwave sensor picks up physical movement or body mass movement (rather than air movement like an ultrasonic sensor). Within the sensor is a microwave generator that creates a mushroom shaped field around the sensor.

This model is a dual zone microwave sensor which has two fields or zones. The first zone detects movement around the vehicle, the second zone detects movement within the car.

It can be added as an optional upgrade to any 12 volt AVS car alarm. Some alarm models (such as the AVS A-Series and S-Series alarms will also need an additional siren added if using a dual zone microwave.

A single zone microwave is also available.
