Professional 4G OBD vehicle tracker you can easily install. With its advanced accelerometer, gyroscope, and special algorithm, can detect improper driving behaviors, precisely calculate mileages, and prevent dark spots occur in areas with poor GNSS signals.


Easily reasigned to another vehicle in minutes


By leveraging different 4G communication modules, it covers almost all global LTE frequency bands. A revolutionary update is the voice alarm, which can remind drivers to behave correctly when their bad driving activities have been detected. Moreover, it also supports the embedded microphone for remote listen-in.




  • Plug into OBDII port allowing easy installation
  • INS-aided GPS Tracking- Ensures constant tracking in the area with poor GPS signal or even without it.

  • Remote Listen-in - Inconspicuous mic allows for remote audio monitoring of the environment around the device.

  • 4G LTE Communication -The device can receive and transmit data in the coverage of 4G, 3G and 2G networks.

  • Voice Alarm - In risky circumstances, internal speaker will sound human voice to remind drivers to drive carefully.

  • Mileage Accuracy ≥98%  - Precise mileage calculation based on a unique algorithm, the mileage error can be less than 2%.

    • BLE4.0 Supported - Through bluetooth connection you can configure parameters, upgrade software, and debug.

    • 9-36V Operating Voltage - Compatible with a wide range of input voltage, able to work on diverse vehicles.

    • Driving Behavior Analysis (Advanced) - Receive alerts when any of 8 kinds of dangerous driving behavior is detected.
