Jablotron has been making quality GPS tracking for many years. Here they have combined their stable GPS with a brilliant car alarm which can even use the same detectors as the JA-100 system. The alarm can be operated in the same APP as the building alarms.
The GPS unit also has logical inputs and outputs so that it can receive signals from and send signals to the vehicle.
History, such as location and speed, is logged in the Cloud so you always have access.
