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)
Acceleration, braking, cornering, sudden lane change, collision, skidding, rollover, roll & pitch.
Mileage Accuracy ≥98%
Precise mileage calculation based on a unique algorithm, the mileage error can be less than 2%.
Voice Alarm
In risky circumstances, internal speaker will sound human voice to remind drivers to drive carefully.
Remote Listen-in
An inconspicuous Mic allows you to remotely listen in the sounds around the device.
9-36V Rated Voltage
Compatible with a wide range of input voltage, able to work on diverse vehicles.
BLE4.0 Supported
Through bluetooth connection you can configure parameters, upgrade software, and debug.
