GPRS function
Positioning function: After the GPS implements satellite positioning, it sends the data such as longitude & latitude, speed and azimuth of the target to the monitoring center. This function can be implemented through Google Earth with the support of an appropriate software system.
Hijack alarm: In case of danger, push the button hidden in the steering room, and the vehicle-mounted system will send alarm signals to the monitoring center until a response is received from the monitoring center.
Tracking: The monitoring center can track the vehicle which raises the alarm after the vehicle is stolen or robbed.
Remote flameout: In the process of rescuing the hijacked vehicle, the monitoring center can extinguish the vehicle remotely by force as required. The system provides double safety, and device fault will not cause accidental flameout.
