VT900-L 4G GPS Tracker
The VT900-L is a Plaspy compatible GPS tracker engineered for professional fleet management and vehicle telematics. Built for reliable real-time tracking and robust anti-theft capabilities, the VT900-L delivers precise positioning and comprehensive telemetry to Plaspy-enabled platforms via TCP/UDP or SMS, with local logging to avoid data loss during coverage gaps.
The compact VT900-L is optimized for vehicle installations and scalable fleet deployments. With multi-band 4G/LTE plus 3G and 2G support, dual GNSS (GPS + BeiDou) and a rich set of I/O interfaces, it integrates easily with fuel monitoring hardware, CANBUS/OBD modules, RFID readers and external accessories to provide the real-time tracking, driver behavior and operational insights fleet managers expect from Plaspy compatible devices.
Key Highlights
- Plaspy compatible real-time tracking with multi-channel reporting (TCP/UDP, SMS) for live location and telematics.
- High-precision GNSS: GPS + BeiDou with MTK MT3337 chipset and position accuracy better than 2.5 m CEP.
- Multi-network cellular: 4G/LTE, 3G and 2G support via Quectel EG91 or BG96 modules for broad regional coverage.
- Comprehensive I/O for telemetry and control: digital inputs/outputs, analog input, 1-Wire, RS232 and accessory power.
- Onboard logging (8 MB) and 500 mAh backup battery to preserve data and send low-power alerts during outages.
- Advanced alarms and reporting: 37+ alarm types, geofence, parking, antenna disconnect, aggressive driving detection and scheduled reporting.
- Compact, vehicle-ready design (9–36 V power input) and temperature-hardened operation for fleet environments.
How It Works with Plaspy
The VT900-L connects to Plaspy using standard telematics protocols and network transports. Location and sensor data are transmitted to Plaspy in real time via TCP/UDP or sent as SMS messages when required. When cellular connectivity is unavailable the unit logs positions locally (8 MB flash) and uploads stored records once the connection is restored, ensuring continuity of fleet telemetry.
- Real-time location and telemetry updates to Plaspy including GNSS position, speed and heading.
- Alarm and event forwarding to Plaspy: geofence breaches, parking, antenna disconnect, low backup battery and aggressive driving alerts.
- Scheduled and conditional reporting (time, distance, mileage) for route, compliance and utilization reports in Plaspy.
- Remote control of digital outputs via Plaspy for actions such as staged immobilization or accessory control (OTA).
- Integration of fuel monitoring and temperature sensor data through wired inputs and 1-Wire for cold-chain use cases.
