Ultrasonic sensor / shock sensor are included

Ultrasonic sensors are designed to provide intrusion detection of vehicles fitted with sliding windows

(as apposed to wind-up) and utilities fitted with canopies. The ultrasonic principle works approximately the same as police radar.
　

A transmitter produces ultra high frequency sound waves, which bounce off all surfaces inside the car.
　

A receiver then picks up the reflected sound waves and sends a trigger signal to the connected alarm

when a change in the shape of the echo is detected. Ultrasonic sensors require a rigid,

 stable perimeter with no air movement, i.e. convertibles will not reflect sound waves and soft-top roof's will move when battered by wind.
