PT502 GPS Tracker

The PT502 is a 4G GPS tracker built for professional fleet management and vehicle security. Green-Gps compatible out of the box, the PT502 delivers reliable real-time tracking, comprehensive telemetry and robust alarm handling so fleet operators can monitor vehicles, drivers and critical signals through Green-Gps's online platform, mobile app or SMS.

Designed for demanding vehicle environments, the PT502 supports advanced features such as driver identification via RFID, ultrasonic fuel sensing for precise fuel monitoring, multi-camera photo capture and remote immobilizer controls. These capabilities make it a strong choice for fleets focused on anti-theft protection, trip replay, maintenance reminders and driver behaviour analysis when integrated with Green-Gps.

Key Highlights

• Green-Gps compatible 4G GPS tracker for real-time tracking and fleet management.
• Supports up to four external cameras for automatic photo capture on alarms and events.
• Driver identification with RFID for secure driver-to-vehicle association and reporting.
• Ultrasonic fuel sensing support for accurate fuel monitoring and discrepancy alerts.
• Remote engine shutdown and speed limitation via external relays (remote immobilizer functionality).
• Flexible alarm suite: SOS, geo-fence, speed, ACC on/off, power cut and hard driving event alarms.
• 2 digital inputs (one negative, one positive-triggering) and 2 outputs for relays, buzzers or sirens.

How It Works with Green-Gps

The PT502 sends position updates and telemetry to Green-Gps using configurable triggers so you get the right data at the right moment. Green-Gps aggregates location, sensor and event data into live maps, alerting rules and historical reports for effective fleet operations, anti-theft response and compliance monitoring.

• Real-time location and telemetry updates delivered to Green-Gps (via 4G/SMS/app/FMS integration).
• ACC/ignition status reporting for accurate engine-on/off tracking and trip segmentation.
• Ultrasonic fuel monitoring data for fuel-level reports and fuel-sensor-triggered alerts.
• Remote immobilizer and speed-limiting control through Green-Gps command functions using the device's outputs and relays.
• Automatic camera photo capture and event images sent with alarm events for visual verification.

Technical Overview

Use Cases

• Fleet anti-theft and immobilization — remotely disable or limit a vehicle via Green-Gps when theft or unauthorized use is detected.
• Driver identification and behaviour monitoring — use RFID plus Green-Gps reporting to track who is driving and generate fatigue or harsh driving alerts.
• Fuel management optimization — integrate ultrasonic fuel sensors to detect fuel theft, measure consumption and reconcile telemetry with trip data.
• Event-driven photo capture and evidence collection — automatic camera photos on alarms (e.g., collision, ignition events or geo-fence breach) for incident verification.
• Maintenance and compliance — automated mileage logging and maintenance reminders to keep fleets service-ready and compliant.

Why Choose This Tracker with Green-Gps

Choosing the PT502 as a Green-Gps compatible GPS tracker gives fleet operators a practical combination of real-time tracking, rich telemetry and actionable alarms. The device’s support for multiple cameras, RFID driver ID and ultrasonic fuel monitoring extends Green-Gps’s visibility into driver behavior, fuel usage and incident verification. Remote immobilizer and speed-limiting capabilities enable quick anti-theft response and policy enforcement, while configurable update triggers (time, distance, angle, movement ratio and ACC status) help balance precision with data costs.

Built with extensive quality-control testing for temperature, vibration, power variation and long-term reliability, the PT502 is positioned as a rugged option for vehicle fleets that need consistent telemetry and dependable integrations. When integrated into Green-Gps’s platform, it supports streamlined fleet management workflows — from live tracking and trip replay to maintenance alerts and driving behaviour reports — helping operators reduce risk, improve efficiency and protect assets.
