JM-VL04
JM-VL04 INS-aided LTE OBD Tracker

OBD Vehicle 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 four 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. And now, not only is the embedded microphone for remote listen-in, but also sound recording.
