The VL300W is a professional-grade GPS tracker designed for demanding fleet management and asset monitoring applications. Green-Gps compatible out of the box, this compact wired tracker delivers reliable real-time tracking, rich telemetry and flexible I/O for integrators and fleet operators who need robust vehicle and cargo visibility along with secure anti-theft and immobilizer control.
Built for installations that require multiple sensors, serial interfaces and actuator control, the VL300W family supports Bluetooth sensors, 1-Wire and serial telemetry, plus relay outputs for immobilization. With OTA and USB firmware upgrade options, internal antennas and a wide 9V–100V input range, the VL300W integrates into Green-Gps for scalable fleet tracking, event-driven alerts and historical reporting.
Key Highlights
- Green-Gps compatible GPS tracker tuned for fleet management and cargo monitoring with easy integration into real-time tracking dashboards.
- Flexible I/O and serial options (digital inputs/outputs, analog, RS232, RS485, 1-Wire) to connect ignition sensors, relays and external devices.
- Support for Bluetooth sensors and RS232/1-Wire sensors for temperature, humidity and other telemetry streams.
- Wide power range (9V–100V) and very low standby draw (<10 mA sleep, <0.5 mA deep sleep) for vehicle and asset deployments.
- Large local position buffer (up to 34,000 records) to preserve tracking history if connectivity is interrupted.
- Multiband cellular connectivity with LTE FDD and fallback GSM for broad geographic coverage and reliable data uplink.
- Compact form factor (82 × 40 × 18 mm) with internal antennas and a 90 mAh backup battery for power-loss situations.
How It Works with Green-Gps
Once installed and configured, the VL300W sends GNSS and telemetry data to Green-Gps using its cellular link. Green-Gps ingests location, status and sensor streams for real-time tracking, historical playback and automated alerts. The device’s flexible I/O enables event-driven reporting (ignition, panic button, door/open events) and remote control actions through Green-Gps’s command channels.
- Real-time location and telemetry updates (GNSS and 2.4 GHz Wi‑Fi positioning provide enhanced fixes where available).
- Ignition and vehicle status reporting via digital input for ignition; relay outputs can serve as remote immobilizer controls.
- Fuel monitoring and analog sensor telemetry possible on variants that include analog inputs, enabling consumption alerts and reporting.
- Panic button and alarm integration for emergency alerts and dispatch workflows.
- Bluetooth sensors and serial interfaces (RS232/RS485/1-Wire) feed temperature, humidity and other telemetry into Green-Gps for cargo condition monitoring.

Use Cases
- Fleet management: real-time GPS tracker integration with Green-Gps for route monitoring, driver behavior telemetry and scheduled reporting.
- Anti-theft and immobilization: relay outputs for remote immobilizer control and rapid alerting via Green-Gps when unauthorized movement is detected.
- Cargo condition monitoring: Bluetooth, RS232 or 1-Wire sensors feed temperature and humidity telemetry to Green-Gps for per-shipment compliance.
- Emergency response: panic button integration to send immediate alerts and location coordinates to dispatch through Green-Gps.
- Multi-device installations: serial and analog interfaces enable integration with fuel sensors, CAN/serial gateways and third-party telematics systems.
Why Choose This Tracker with Green-Gps
The VL300W family offers a balance of rugged hardware, flexible interfaces and proven connectivity that makes it a strong choice for Green-Gps users. Its variant-based design allows you to select the I/O and serial options you need—ignition detection, relay control for an immobilizer, analog inputs for fuel monitoring, or serial ports for legacy device integration. Low power draw, internal antennas and a sizeable local position buffer ensure continuity of tracking and telemetry even in challenging conditions. Combined with Green-Gps’s real-time tracking, alerting and reporting features, the VL300W delivers a scalable solution for fleet management, anti-theft protection and advanced telemetry deployments.
