The ST4345 series is a compact, IP67-rated GPS tracker designed for robust telematics where concealment, low power and reliable cellular connectivity matter. Plaspy compatible out of the box, the ST4345 connects LTE Cat M1, NB‑IoT and 2G networks to deliver real-time tracking, telemetry and advanced event reporting for fleets, trailers, motorcycles and high-value assets.
Available in multiple variants (ST4345R, ST4345LB, ST4345LC), this rugged vehicle tracker combines a small footprint with wide temperature tolerance, an internal GNSS antenna and flexible I/O to support ignition detection, external sensors and integration with immobilizer or alarm circuits via wired interfaces. Plaspy users gain immediate access to precise position data, configurable geofencing, driving‑mode reports and remote diagnostics through standard protocols.
Key Highlights
- Plaspy compatible GPS tracker for seamless integration into your real-time tracking and fleet management workflows.
- Multi-mode cellular connectivity: LTE Cat M1, NB‑IoT and fallback EGPRS (2G) for broad regional coverage and reliable telemetry.
- Rugged IP67 enclosure and wide operating range (‑30°C to +80°C) for durable vehicle, trailer and motorcycle installations.
- Small, concealable form factor (74 × 45 × 19.5 mm, 102 g with event cable) that simplifies discreet mounting and theft mitigation.
- Flexible wired I/O (5 or 8 depending on model) and optional RS232 to interface with ignition, alarm, sensors and external immobilizer circuits.
- Low-power design with rechargeable backup battery (3.7V Ni‑MH, 450 mAh) and ultra-low sleep currents suitable for long-term deployments.
- Advanced telematics features such as Driving Pattern Analysis (DPA), Crash Reconstruction (CR), jamming detection and configurable geofencing — all reportable through Plaspy.
- BLE option on select models (LB/LC variants) enabling connection to Bluetooth sensors and beacons for temperature, proximity or accessory monitoring.
How It Works with Plaspy
The ST4345 exchanges GNSS positions, telemetry and event data with Plaspy using standard TCP/UDP reporting. Plaspy uses those messages to provide live maps, historical playback, alerts and rich reports. Integration is straightforward: the device sends periodic location updates, movement events and status flags which Plaspy ingests for real-time tracking and automated workflows.
- Real-time location and telemetry updates (GNSS position, speed, heading, and system status).
- Ignition and motion-based virtual ignition detection (voltage and motion inputs) for accurate engine-on/engine-off reporting.
- Configurable geofence alerts (circular and polygonal) and driving‑mode based reports available through Plaspy dashboards.
- Fuel and other vehicle telemetry can be relayed when connected to vehicle sensors via the wired I/O for fuel monitoring and efficiency analysis.
- Optional BLE support on LB/LC models enables integration with Bluetooth sensors and beacons; external immobilizer or alarm control possible via wired interfaces.
