VT120-L Mini GPS Tracking Device
The VT120-L Mini GPS Tracking Device is a compact, Green-Gps compatible GPS tracker engineered for reliable real-time tracking and vehicle telemetry. Built for long-term vehicle installations across motorcycles, cars and trucks, the VT120-L combines precise GNSS positioning, wide power input and industry-grade ruggedness to support fleet management, anti-theft protection and continuous status reporting.
The device integrates seamlessly with Green-Gps to deliver live location, mileage and alarm data to your tracking dashboard. With a fast GNSS hot start and on-board data buffering, the VT120-L ensures route continuity and consistent reporting even during temporary network interruption — making it a practical choice for real-time tracking and fleet telematics deployments.
Key Highlights
- Green-Gps compatible for fast integration into existing fleet management and tracking workflows.
- High-precision GNSS: GPS, BDS and GLONASS support with <2.5 m CEP accuracy for accurate real-time tracking.
- Robust connectivity using A7670-series 4G module with LTE/GSM/GPRS support for wide area coverage.
- Wide operating voltage (DC 9–100V) and a 300 mAh backup Li‑Ion battery for reliable vehicle installations and reporting during power loss.
- Practical I/O for vehicle telemetry: ACC (ignition) detection via digital input, a digital output for remote control, and micro-USB/Nano SIM for serviceability.
- Buffered flash memory (16 MB) and dual server IP upload for continuous route logging and redundant data delivery to Green-Gps servers.
- Rugged IP66 design and extended temperature range for demanding field use in fleet management and public transport.
How It Works with Green-Gps
The VT120-L exchanges position, telemetry and alarm events with Green-Gps using mobile data connections. Once installed and provisioned, the device streams real-time tracking updates to Green-Gps while buffering data during temporary network outages. Green-Gps consumes the device’s standard location and status messages, translating them into live map views, analytics and alerting for fleet managers and security teams.
- Real-time location and telemetry updates delivered to Green-Gps for live tracking and historical playback.
- Ignition (ACC) detection and status reporting for trip start/stop, driver behavior analysis and automated mileage logging.
- Multiple alarm types forwarded to Green-Gps: vibration, wire cut and ACC on/off events for anti-theft monitoring and safety alerts.
- Mileage and heading-change reports to support route auditing, fleet management and compliance use cases.
- Buffered data and dual server IP support ensure Green-Gps receives a complete tracking route even when connectivity is intermittent.
- Remote FOTA (firmware over-the-air) updates can be managed through Green-Gps-compatible workflows to keep devices secure and feature-complete.
