The VT900-G 3G GPS tracker from VT (model VT900-G) is a professional-grade vehicle tracking device engineered for reliable Plaspy compatible deployment. Designed for fleet managers, rental operators, and vehicle security applications, the VT900-G combines high-sensitivity GNSS positioning with UMTS/HSDPA and GSM/GPRS cellular connectivity to deliver accurate real-time tracking, event alerts, and telemetry to Plaspy's platform, mobile apps, or SMS clients.
Built for robust vehicle telematics, the VT900-G supports OBD/CANBUS diagnostics, multiple external sensors, RFID readers via RS232, and optional ultrasonic or capacitive fuel sensors. Its internal flash memory stores coordinates during network outages so Plaspy receives continuous trip history once connectivity is restored—making this GPS tracker a practical choice for anti-theft protection, fuel monitoring, and fleet management at scale.
Key Highlights
- Plaspy compatible for seamless integration into real-time tracking and fleet management workflows.
- High-sensitivity GPS + Beidou positioning (SiRF-Star IV chipset) for typical 2.5 m position accuracy and 0.1 m/s velocity accuracy.
- UMTS/HSDPA and GSM/GPRS cellular connectivity for broad 3G/2G coverage and reporting to server platforms, apps, or SMS.
- Extensive I/O and peripherals: OBD/CANBUS, RS232 ports for RFID/MSR, 3 digital inputs / 2 digital outputs, and analog inputs for sensors.
- Built-in 8MB flash memory buffers tracking data offline; 500mAh backup battery maintains operation during power interruption.
- Supports fuel monitoring options (capacitive and ultrasonic sensors) and temperature sensors for cold-chain logistics.
- More than 37 alarm/event types for driver behavior monitoring, anti-theft alerts, and safety protection.
How It Works with Plaspy
When deployed with Plaspy, the VT900-G forwards location, telemetry, and event data to Plaspy’s servers using cellular networks. Plaspy ingests GNSS fixes, CANBUS diagnostics, and sensor readings to provide live tracking, geofencing, and standardized reports for fleet management and anti-theft monitoring. The device’s local flash memory ensures no tracking gaps: queued records are uploaded to Plaspy when the network is available again.
- Real-time location and telemetry updates to Plaspy via UMTS/HSDPA or GSM/GPRS.
- Ignition, door, and alarm status through configurable digital inputs and event rules for driver behavior monitoring.
- Fuel monitoring supported via OBD/CANBUS and optional ultrasonic or capacitive fuel sensors for accurate fuel consumption data.
- Remote immobilizer / engine shut-off capability using digital outputs for anti-theft and fleet control actions.
- Temperature sensor inputs for cold-chain cargo monitoring and alerts in Plaspy dashboards.
- Buffered data upload: internal flash stores coordinates and events during network outages and syncs with Plaspy when online.
