The ST4305 series is a rugged vehicle GPS tracker designed for fleet managers and vehicle recovery services that require reliable Plaspy compatible hardware. Built for multi‑network cellular coverage (LTE Cat M1, NB‑IoT and 2G), the ST4305 family delivers continuous real‑time tracking and rich telemetry suited to fleet management, anti‑theft and safety use cases.
Available in multiple variants (ST4305, ST4305R and ST4305RE), this wired tracker combines integrated GNSS positioning, a 14‑pin connection harness and configurable reporting to simplify integration with Plaspy for actionable vehicle insights, driver behavior monitoring and remote diagnostics.
Key Highlights
- Plaspy compatible GPS tracker with LTE Cat M1, NB‑IoT and 2G connectivity for wide area coverage and cost‑effective data transport.
- Variants to suit installation needs: ST4305 (basic I/O), ST4305R (adds RS‑232) and ST4305RE (RS‑232 plus external GNSS antenna provision).
- Advanced telematics features including Driving Pattern Analysis (DPA) with Crash Reconstruction (CR) and optional jamming detection for enhanced security and incident review.
- Virtual ignition detection (voltage and motion based) and configurable reports to support fleet management, driver behavior analysis and compliance reporting.
- 14‑pin wired interface with multiple inputs/outputs for integration with alarms, door/ignition circuits and third‑party immobilizer or alarm systems.
- Backup 450 mAh battery preserves telemetry and location reporting during power loss for recovery and anti‑theft scenarios.
- Support for maintenance server workflows and downloadable firmware/files (ST4305.pdf) to speed deployment and ongoing device management.
How It Works with Plaspy
The ST4305 integrates with Plaspy to deliver real‑time tracking, telemetry and event reporting. Plaspy ingests location and device telemetry sent by the ST4305 and uses configurable report formats to produce live maps, alerts and historical reports that fleet managers rely on for operational decisions.
- Real‑time location and telemetry updates: GNSS positions and movement data are transmitted over LTE Cat M1 / NB‑IoT / 2G to Plaspy for live tracking and replay.
- Ignition and motion status: virtual ignition detection (voltage and motion based) enables Plaspy to determine vehicle on/off state and trigger ignition‑based reports or workflows.
- Geofence and security alerts: circular and polygonal geofencing events are reported to Plaspy for geofence breach notifications and route enforcement.
- Crash and driving events: Driving Pattern Analysis (DPA) and Crash Reconstruction (CR) events can be sent to Plaspy for safety analysis and automated incident reporting.
- Jamming detection and power loss: optional jamming detection and backup battery status are reported to Plaspy for anti‑theft monitoring and recovery assistance.
- Serial telemetry and antenna options: ST4305R/RE variants provide RS‑232 output for integration with vehicle CAN/OBD2 gateways or third‑party modems; the RE model also supports an external GNSS antenna for improved reception.
