The VL502 is a new generation of 4G Cat 1 OBD II tracker for corporate cars, usage-based insurance, fleet management, and individual cars, which can obtain vehicle data such as VIN code, engine speed, water temperature, accumulated mileage, etc. With the UBI-based algorithm for driving behavior analysis, the VL502 can accurately analyze any of 4 kinds of dangerous driving behavior and support the all-round monitoring of vehicles’ real-time status.

LTE & GSM Network
LTE & GSM Network Communication via 4G LTE networks with 2G GSM fallback.
On-Board Diagnostics
On-Board Diagnostics Obtains real data of vehicle (accurate mileage, fault code, ACC status, fuel consumption statistics, battery voltage, engine speed, etc.)
GPS & BDS Positioning
GPS & BDS Positioning Two complementary positioning systems ensure the locations to be accurately displayed on cloud platform.
Driving Behavior Analysis
Driving Behavior Analysis Get instant alerts for 4 or 8 kinds of dangerous driving behavior, depending on your needs.
Multiple Alerts
Multiple Alerts Instant alerts for atypical events such as car fault, overspeed, ignition detection, collision, geo-fence entry/exit, etc.
BLE4.2 Supported
BLE4.2 Supported Through bluetooth connection you can configure parameters, upgrade software, and debug.
INS-aided GPS Tracking (Optional)
INS-aided GPS Tracking (Optional) Ensures constant tracking in the area with poor GPS signal or even without it.
