How It Works with Secure GPS
Integrating the VL350 into Secure GPS enables continuous, Secure GPS compatible real-time tracking and a unified view of trailer telemetry and events. The device reports multi-source location data and status updates via 4G LTE to Secure GPS’s platform, where you can configure alerts, geofences, and immobilization workflows. VL350’s BLE connectivity and serial interfaces allow Secure GPS to ingest sensor readings and vehicle telemetry for richer operational insight.
- Real-time location and telemetry updates delivered over Global 4G LTE Cat.1 for fleet management dashboards.
- ACC ignition status reporting to track vehicle powered/on/off states and trigger event-driven rules.
- Remote oil/electric cut-off (immobilizer) control to support anti-theft and recovery procedures from Secure GPS.
- BLE 5.0 sensor integration for door, cargo, and temperature monitoring sent into Secure GPS as sensor telemetry.
- Serial (RS232/RS485) and GPIO inputs for external telemetry, CAN data, or alarm status mapped into Secure GPS reports.
