PT621 4G Vehicle GPS Tracker

The PT621 is a rugged 4G vehicle GPS tracker engineered for fleet management, vehicle security, and specialized monitoring applications. Green-Gps compatible out of the gate, the PT621 delivers reliable real-time tracking and configurable telemetry so fleets, logistics operators, and service managers can maintain visibility and control across vehicles and assets.

The unit supports multi-channel connectivity (4G/GPRS and SMS) and integrates with FMS platforms to deliver location, sensor data, alarms, and event-driven reports into Green-Gps. With remote engine cut via external relay, two-way voice capability, automated photo capture, and extensive sensor interfaces, the PT621 is designed to reduce theft, optimize vehicle utilization, and surface actionable telematics for better operational decisions.

Key Highlights

• Green-Gps compatible real-time tracking over 4G/GPRS and SMS for continuous fleet visibility.
• Remote engine cut via external relay for effective anti-theft and immobilizer control.
• Support for up to four external cameras to capture automated photos tied to events.
• Driver identification via external RFID sets to link drivers to trips and behavior data.
• Comprehensive alarm set (SOS, geo-fence, speed, fuel/temperature, ACC, antenna cut, and more) with SMS/call/email notifications.
• Flexible inputs/outputs and sensor support for fuel monitoring, temperature, door status, and other vehicle telemetry.
• On-board features for safety and compliance: speed limiting, buzzer reminders, LED message display, and driving behavior analysis.

How It Works with Green-Gps

Integrating the PT621 with Green-Gps brings vehicle position, event data, and sensor telemetry into a single operational console. The device reports using 4G/GPRS and can fall back to SMS for essential alerts. Green-Gps ingests the device’s position updates, alarms, and sensor readings and presents them as live maps, alerts, and historical reports for fleet managers.

• Real-time location and telemetry updates delivered to Green-Gps via 4G/GPRS (and SMS for critical notifications).
• Ignition and door status reporting (ACC on/off), plus configurable alarm triggers such as geo-fence and speed violations.
• Fuel monitoring and temperature sensor integration for fuel-theft prevention and cold-chain logistics alerts.
• Remote immobilizer capability through external relay for safe engine cut when needed.
• Event-triggered photo capture from up to four external cameras; images can be linked to Green-Gps events where platform support exists.

Technical Overview

Use Cases

• Fleet management: real-time tracking, driver identification, and driving behavior analysis to improve safety and utilization.
• Cold-chain logistics: temperature sensor integration and high-temperature alarms for refrigerated transport monitoring.
• Anti-theft and immobilization: remote engine cut, GPS antenna cut detection, and SOS alarms to protect high-value vehicles.
• Fuel monitoring and prevention: support for ultrasonic and wired fuel sensors to detect discrepancies and deter fuel theft.
• On-site enforcement and safety: speed limiting, over-speed buzzer reminders, LED screen messages, and automated photo capture for incident documentation.
