The Queclink GV300 is a proven, Plaspy compatible GPS tracker designed for demanding vehicle telematics. As Queclink’s third‑generation vehicle tracker and a long‑running best seller, the GV300 delivers real‑time tracking, robust telemetry and flexible I/O options that make it an ideal foundation for Plaspy‑powered fleet management, stolen vehicle recovery and cold‑chain applications.
Built around a high‑sensitivity u‑blox GNSS receiver and quad‑band GSM connectivity, the GV300 combines compact vehicle‑grade hardware, a wide operating voltage range and a comprehensive set of wired interfaces. When paired with Plaspy, the GV300 provides configurable alarms, scheduled reporting, CAN and analog data capture, and remote control capabilities that support anti‑theft workflows, ignition monitoring and advanced telematics use cases.
Key Highlights
- Plaspy compatible GPS tracker with proven deployment in fleet management, insurance telematics and stolen vehicle recovery.
- Real‑time tracking and scheduled reporting (time/distance/mileage) via TCP/UDP or SMS for resilient communications.
- Extensive wired I/O: ignition detection, multiple digital inputs/outputs, analog inputs and RS232 for accessory integration and telemetry.
- High‑sensitivity GNSS (u‑blox) with typical position accuracy under 2.5 m CEP for reliable location data.
- Compact, vehicle‑grade form factor with wide operating voltage (8–32 V DC) and internal backup battery for power‑loss events.
- Supports CAN data capture (via CAN adapter) and partner temperature/humidity sensors for cold‑chain or environmental monitoring.
- Operational alarms including geo‑fence, tow, antenna disconnect, crash detection and driving behavior monitoring.
How It Works with Plaspy
The GV300 feeds rich telemetry and event data into Plaspy’s platform using standard transmit protocols and queued reports. Plaspy ingests GNSS position, digital/analog state changes, CAN frames (when used), and device alarms to power dashboards, alerts and automated workflows for fleet managers and security teams.
- Real‑time location and telemetry updates via TCP/UDP and SMS transport supported by the device.
- Ignition detection and status tracking using the dedicated positive trigger input for engine/ignition events.
- Fuel monitoring and other analog sensor telemetry possible through analog inputs or CAN data capture for integration with Plaspy reports.
- Remote immobilizer or stoppage workflows enabled through OTA control of digital outputs (remote output control supported).
- Temperature/humidity sensor integration via partner accessories for cold‑chain monitoring accessible in Plaspy dashboards.
