Impact sensors, also know as shock sensors, are designed to detect impacts to the vehicle. There are 2 levels of detection (depending on alarm functions). The first stage just chirps the siren if the sensor detects light impacts to warn away any other possible attack. Heavier impacts cause the alarm to sound fully.
All models are adjustable for sensitivity.
