The AT4 is a portable, magnet-mounted GPS tracker designed for long standby deployments and rugged field use. Plaspy compatible out of the box, the AT4 gives fleet managers and asset owners reliable location intelligence, tamper alerts, and discreet audio monitoring for improved anti-theft protection and operational oversight.
The AT4 combines GPS+LBS positioning with a high-capacity 10,000mAh battery and an IPX5-rated enclosure to deliver extended deployments without maintenance. Compact and easy to install with a strong magnetic base, the AT4 is an ideal choice for fleet management, vehicle rental, trailer tracking and other asset tracking scenarios where long battery life, tamper detection and remote telemetry are essential.
Key Highlights
- Plaspy compatible GPS tracker that reports accurate location and movement to your Plaspy dashboard in real time.
- Ultra-long standby: 10,000mAh industrial Li‑Polymer battery with up to 2.5 years standby in power‑saving mode for low-maintenance deployments.
- Rugged, IPX5-rated enclosure and strong magnetic mount for near-zero installation on vehicles, trailers, and other assets.
- GPS+LBS positioning with <2.5 m CEP accuracy under optimal conditions and fast TTFF (hot start ≤1 s, cold start ≤32 s).
- Integrated microphone for remote audio monitoring (effective to ~3 meters), plus accelerometer-based vibration detection and over-speed alerts.
- Tamper-aware design with a pressure-sensitive tamper button and immediate cover-removal alerts to enhance anti-theft workflows.
- On-device data storage and quad-band GSM connectivity for broad network coverage using a standard SIM.
How It Works with Plaspy
When integrated with Plaspy, the AT4 streams location, status, and event data into your real-time tracking and fleet management workflows. Plaspy ingests GNSS and GSM-derived positions, telemetry and event notifications from the device so you can view live positions, replay routes, set geo-fences, and respond to security events from a single pane of glass.
- Real-time location and telemetry updates delivered to Plaspy for live tracking and historical plays.
- Tamper and power-off notifications routed to Plaspy to trigger alerts and escalation policies.
- Over-speed, vibration and geo-fence events reported directly to Plaspy for automated alerting and reporting.
- Remote audio monitoring capability (microphone) accessible through Plaspy where audio monitoring is enabled and permitted.
- On-device storage buffers location data if connectivity drops, allowing Plaspy to receive cached reports when the connection resumes.
