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.
Authorized wiretapping: The vehicle can be wiretapped as authorized (a tiny microphone needs to be installed).
Internal flash memory: When the T800A  is disconnected to the system (for example, the GPRS signal is weak), the position data will be storing in the flash, and then it will upload again after it reconnect to the system (the GPRS signal is ok).
support serial cameras, monitor the image information around the terminal.
