The VL111 is a compact 4G LTE tracking terminal with a built-in GNSS module that supports GPS and BeiDou to determine the location of the vehicle in real time and a built-in relay that allows the manager or operator to remotely cut off the fuel or power supply to the vehicle when an exception occurs. The VL111 also offers features such as historical trip playback and automatic power disconnection in the event of a low external battery.
