A tow alarm fires when a GPS tracker detects the vehicle moving while the ignition is off. If a van is parked overnight and someone tows it away, the tracker sends an immediate alert with the live GPS position – long before the theft would normally be discovered the next morning.
The alarm uses the device’s accelerometer and ignition input together. Ignition off + movement detected = tow alarm. This distinguishes genuine towing from normal parking movement caused by other vehicles bumping the asset.
- Response time – alert is sent immediately on detecting movement in ignition-off state
- GPS position included – alert contains the last known position and the position at the time of movement
- Combined with geofencing – if the vehicle leaves the depot geofence at night, both a geofence alert and a tow alarm are generated
- Insurance benefit – rapid notification improves recovery rates significantly compared to next-morning discovery
