How It Works with Plaspy
When paired with Plaspy, the PT81 streams location and status data to the platform for real-time tracking, alerts and historical playback. Plaspy ingests the PT81’s multi-mode positioning and sensor events, routes SOS and voice communications, and publishes notifications to caregivers or managers. Integration requires adding the device to your Plaspy account and configuring alerts and reporting intervals to balance timeliness and battery life.
- Real-time location and telemetry updates via 4G cellular and positioning (GPS/BeiDou/Wi‑Fi/LBS).
- SOS alarm and two-way voice (supported) for direct emergency calls and remote listening.
- Geo-fence, fall detection (gravity sensor), low-battery and historical track playback through Plaspy alerts and timeline views.
- Device-finder function (rings the tracker) and short app voice messaging for nearby assistance and check-ins.
- Note: The PT81 is optimized for personal safety and wearable tracking. For vehicle telemetry features such as fuel monitoring, ignition monitoring or remote immobilizer control, Plaspy supports dedicated vehicle trackers and sensors that can be mixed in the same platform deployment.
