Motion and Tilt Sensor Alarms
Another method of car or motorcycle security, a mercury balance switch is used to sound an alarm when a car is moved excessively (such as during a violent break-in or, as expensive cars sometimes suffer, being towed away by more enterprising criminals.) Most higher-range car alarms feature some kind of motion sensor.
