The SinoTrack Relay ST-907L is a compact, Plaspy compatible GPS tracker engineered for motorcycles and cars that need dependable real-time tracking and remote vehicle control. With dual GPS/GLONASS positioning, a high‑sensitivity SIMCOM 7670SA GNSS module, and support for both 4G LTE and 2G GSM networks, the ST-907L delivers consistent location fixes, fast AGPS acquisition, and resilient anti-pseudo-base-station protection for secure telemetry and anti-theft use.
Designed for fleet management and personal vehicle security, the ST-907L’s small form factor and wide operating voltage (10–50 V) make installation straightforward across 12V and 24V vehicles. When paired with Plaspy, this Plaspy compatible unit provides live map views, route history, geofence alerts, remote immobilization, and the telemetry needed to improve uptime and reduce theft risk.

How It Works with Plaspy
When connected to Plaspy, the ST-907L streams location and telemetry data to your centralized Plaspy account so you can monitor assets in real time, configure alerts, and generate historical reports. Plaspy reads the tracker’s GNSS fixes, event alarms, and mileage data to provide an actionable view for operations, dispatch, and security teams.
- Real-time location and telemetry updates — live map tracking and periodic position reports.
- Geofence creation with SMS and app notifications for entry/exit alerts and perimeter control.
- Vibration/displacement, power‑off, low battery and overspeed alarms forwarded to Plaspy for instant notification.
- Remote immobilizer (engine cut‑off and resume) supported by the device for anti-theft response via Plaspy controls.
- Mileage reporting for fleet analytics and basic telemetry; fuel monitoring can be aggregated in Plaspy when external sensors are used or provided through integrated fleet telematics workflows.
- AGPS-assisted fast fix times and anti-pseudo-base-station detection help maintain accurate, trustworthy data in Plaspy dashboards.
