The concept

The vehicle alarm system responds to:

▷ Opening of a door, the hood or the trunk lid.
▷ Movements in the vehicle.
▷ Changes in the vehicle tilt, e.g., during attempts to steal a wheel or when towing the car.
▷ Interruptions in battery voltage.

The alarm system briefly indicates tampering:
▷ By sounding an acoustic alarm.
▷ By switching on the hazard warning system.
▷ By flashing the high beams.
