SinoTrack - ST-901

The ST-901 4PIN Tracker from SinoTrack is a compact, waterproof wired GPS tracker designed for motorcycles, scooters, cars and light trucks. Built for discreet installation and reliable cellular reporting, the ST-901 provides GPS/GPRS/SMS positioning, geo-fence and over-speed alerts, ACC ignition detection, and a built-in backup battery for main power-off alarms. Its simple 4-pin wiring and external relay support let fleet managers and vehicle owners add remote engine cut-off (immobilizer) for anti-theft protection.

Green-Gps-compatible out of the box when configured to report to a third‑party server, the ST-901 integrates with cloud tracking platforms via standard GPRS/SMS reporting. Configure the device with SMS commands to point it at Green-Gps’s server IP and port, and you get real-time tracking, telemetry and alerting in Green-Gps alongside SinoTrack’s free web and mobile platform. This makes the ST-901 a practical, cost-effective choice for fleet management and vehicle security deployments that require dependable position updates and remote immobilization.

How It Works with Green-Gps

The ST-901 transmits positional data and alarm events using standard GPS/GPRS/SMS modes. To integrate with Green-Gps, configure the device’s server IP, port and APN via the manufacturer’s SMS commands so the tracker forwards its packets to Green-Gps’s ingestion endpoint. Once connected, Green-Gps receives location, status and alarm messages for real-time tracking, reporting and rule-based alerts.

• Real-time location and telemetry updates: GPS coordinates are sent over GPRS to the configured server for live tracking in Green-Gps.
• Ignition (ACC) status and main power alarm: ACC detection reports ignition on/off; internal battery triggers alerts on main power loss.
• Geo-fence and over-speed alerts: boundary breaches and speed violations generate immediate events to Green-Gps and SMS notifications.
• Remote immobilizer (engine cut-off): connect an external relay through the 4-pin interface to enable remote engine or fuel circuit control for anti-theft actions.
• SMS failover and direct alerts: the unit can send SMS alerts (including Google Maps links) when immediate notification is required or GPRS is unavailable.
• Activation and IMEI considerations: configure via SMS commands (server IP/port and APN). Note local IMEI registration rules may apply in some countries and the device supports IMEI read/change commands per the manufacturer guidance.

Technical Overview

Use Cases

• Fleet management: track vehicles in real time with Green-Gps for route oversight, driver monitoring and simple telemetry reporting.
• Anti-theft protection: remotely immobilize a vehicle by triggering an external relay connected to the ST-901 to cut ignition or fuel circuit when a theft event is detected.
• Two‑wheeler security: discreet, waterproof installation on motorcycles and scooters to provide location tracking and power-cut alerts where compact form factor is essential.
• Alarm-driven operations: receive geo-fence, main power-off and over-speed alarms in Green-Gps and via SMS for quick incident response.
• Backup notification: use SMS alerts (with Google Maps links) for rapid sharing of vehicle location when data connectivity is limited.
