How It Works with Plaspy
When paired with Plaspy, the TK820 streams location and status updates so fleets and caregivers receive timely, actionable information. Plaspy ingests the device’s GNSS and auxiliary positioning data, translates movement and alert events into notifications, and stores historical telemetry for review and compliance reporting.
- Real-time location and telemetry updates: GNSS coordinates plus LBS/WiFi-assisted fixes feed Plaspy for continuous tracking.
- Movement & vibration alerts: built-in vibration sensor triggers instant notifications for suspected tampering or motion.
- SOS emergency calls: SOS button events generate priority alerts and allow immediate voice contact routing via Plaspy notifications.
- Geofence and over-speed alarms: geofence breaches and speed thresholds are reported in real time to Plaspy for automated alerts.
- Historical routes and playback: up to six months of server-stored route data is available in Plaspy for audit, route analysis, and playback.

Why Choose This Tracker with Plaspy
Pairing the TK820 with Plaspy delivers a pragmatic balance of portability, robust positioning and event-driven alerts. For organizations and families that need dependable real-time tracking, the TK820’s multi-constellation GNSS support, LBS/WiFi augmentation, and vibration/SOS features provide clear telemetry to Plaspy’s dashboards and mobile notifications. The device’s long battery life, IP65 rating, and server-backed route history (up to six months) make it a reliable addition to Plaspy-compatible deployments.
While some fleet solutions also integrate fuel monitoring, ignition or immobilizer controls, and Bluetooth sensors, the TK820 focuses on comprehensive location and alerting capabilities. For customers requiring additional telemetry such as fuel or immobilizer control, Plaspy can consolidate TK820 location data with supplementary sensors or gateways supported by the platform to create a fuller fleet management or anti-theft solution.
