JM-VL04 LTE OBDII GNSS Tracker
The JM-VL04 is a professional 4G OBD vehicle tracker you can easily install. With its advanced accelerometer, gyroscope, and special algorithm, JM-VL04 can detect improper driving behaviors, precisely calculate mileages, and prevent the dark spots occur in the area with poor GNSS signal. 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.
INS-aided GPS Tracking
Ensures constant tracking in the area with poor GPS signal or even without it.
4G LTE Communication
The device can receive and transmit data in the coverage of 4G, 3G and 2G network.
Driving Behavior Analysis (Advanced)
Receive alerts when any of 8 kinds of dangerous driving behavior is detected.
Mileage Accuracy ≥98%
Precise mileage calculation based on a unique algorithm, the mileage error can be less than 2%.
In risky circumstances, internal speaker will sound human voice to remind drivers to drive carefully.
Inconspicuous mic allows for remote audio monitoring of the environment around the device.
9-36V Operating Voltage
Compatible with a wide range of input voltage, able to work on diverse vehicles.
Through bluetooth connection you can configure parameters, upgrade software, and debug.
