Product Overview
A compact waterproof vehicle tracker combining LTE Cat 1 bis connectivity, 2G fallback, multi-constellation GNSS positioning, driving behaviour monitoring, security alerts, and BLE accessory connectivity.
The GV37CEU uses LTE Cat 1 bis connectivity with 2G fallback to maintain communication across different network coverage areas. It transmits location and status information through TCP, UDP, or SMS, with reporting configurable by time, distance, mileage, or a combination of these settings.
The tracker supports GPS, BeiDou, Galileo, and GLONASS for vehicle positioning. Its autonomous positioning accuracy is under 2 metres, with an average cold start time of 28 seconds and a hot start time of approximately 1 second under open-sky conditions.
Monitor vehicle movement and driving behaviour using motion detection, virtual ignition detection, and driving behaviour alerts. The device detects harsh braking and acceleration, while crash detection collects information to support incident analysis.
Configure up to 20 geofence regions and receive alerts for entry, exit, parking, speeding, towing, and unusual motion. Additional functions include jamming detection, low backup battery alerts, power-on reporting, and SOS alarms.
The GV37CEU accepts a 9–90V DC power supply and includes a 200mAh Li-Polymer backup battery. Its IP67-rated waterproof enclosure is designed for demanding vehicle installations, with an operating temperature range of −30°C to +70°C.
Built-in BLE 5.4 allows the GV37CEU to act as a gateway for compatible accessories, including beacons, temperature sensors, and door sensors. Digital and configurable inputs, a latched digital output, and a Micro USB interface support vehicle integration and device configuration.
