Automobile -159dBm, DC 12V GSM / GPRS Tracking Device / Real Time GPS Car Tracker

Product Functions:

1.Signal detecting and control: 9 routes signal sensor, 11 vehicle status detecting, intelligence mode and forced mode to cut fuel/circuit.

2. Alarm: 18 alarms, 3 modes of alarm (include anti-dismantle alarm for SIM card).

3. Monitoring: vehicleautomatic tracking/monitoring, regions setting, geo-fence, GPS mileage statistics, blind area supplementary report, traces storage, base station positioning.

4. Road detecting: road detecting, road detecting calculation, departure alarm, speeding alarm, entry/exit station report…

5. Remote update: main device’s program was support to remote download; user can renew the program remotely.


Power saving mode: in this mode, GPS device’s working current will drop to15mA@12V when vehicle was in flameout.

Car battery over discharge protection: it will switch to supply power by backup battery if car battery’s voltage is very low (10.5V).

Over voltage protection: it will cut the external circuit to protect GPS device if the voltage exceeds limit value (60V).
