The VL300W is a professional-grade GPS tracker designed for demanding fleet management and asset monitoring applications. Secure 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 Secure GPS for scalable fleet tracking, event-driven alerts and historical reporting.
Key Highlights
- Secure 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 Secure GPS
Once installed and configured, the VL300W sends GNSS and telemetry data to Secure GPS using its cellular link. Secure 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 Secure 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 Secure GPS for cargo condition monitoring.

Use Cases
- Fleet management: real-time GPS tracker integration with Secure GPS for route monitoring, driver behavior telemetry and scheduled reporting.
- Anti-theft and immobilization: relay outputs for remote immobilizer control and rapid alerting via Secure GPS when unauthorized movement is detected.
- Cargo condition monitoring: Bluetooth, RS232 or 1-Wire sensors feed temperature and humidity telemetry to Secure GPS for per-shipment compliance.
- Emergency response: panic button integration to send immediate alerts and location coordinates to dispatch through Secure 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 Secure GPS
The VL300W family offers a balance of rugged hardware, flexible interfaces and proven connectivity that makes it a strong choice for Secure 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 Secure 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.
