GOTOP - D22-4G

The D22-4G Waterproof GPS Tracker is a purpose-built, Green-Gps compatible vehicle terminal that brings industrial-grade reliability to real-time tracking and fleet management. Designed for cars, commercial vehicles, and fleet assets, the D22-4G pairs high-sensitivity GPS/BDS dual-satellite positioning with robust 4G LTE communications and built-in antenna hardware to deliver consistent location, telemetry, and status data into the Green-Gps platform.

With features tailored for anti-theft protection, telemetry reporting, and remote vehicle control, the D22-4G supports ACC/ignition detection, door sensor input, overspeed and vibration alarms, mileage statistics, and remote fuel cut-off via an external relay (immobilizer function). Its waterproof, industrial form factor and low-power sleep modes make it suited for long-term fleet installations and theft recovery workflows managed through Green-Gps.

Key Highlights

• Green-Gps compatible for seamless integration into your real-time tracking and fleet management dashboards.
• 4G LTE communications with built-in GSM antenna and full built-in antenna design for reliable connectivity.
• High-sensitivity GPS/BDS dual-satellite positioning and anti-jamming ceramic antenna for accurate location fixes.
• Comprehensive telemetry: ACC/ignition detection, mileage statistics, overspeed and movement alarms, and power-failure alerts.
• Anti-theft and immobilizer capability via remote fuel cut-off using an external relay; SOS alarm to monitoring numbers and platforms.
• Built-in 3-axis acceleration sensor and integrated acceleration algorithm for precise event detection and vibration sensing.
• Two-way voice support with built-in speaker and microphone for listen-in and hands-free communication.
• Large-capacity offline storage and blind-area data retransmission to ensure data continuity in poor coverage.

How It Works with Green-Gps

The D22-4G streams vehicle location and telemetry into Green-Gps over TCP/IP, enabling real-time tracking, alerting, and historical reporting. Green-Gps ingests the device's status messages and sensor inputs so fleet managers can monitor vehicle health, events, and security from a single interface. Offline buffering and blind-area retransmission ensure Green-Gps receives a complete data trail even when the vehicle moves through coverage gaps.

• Real-time location and telemetry updates: GPS/BDS coordinates, movement, and speed delivered to Green-Gps via 4G TCP/IP.
• Ignition and door status: ACC detection and door sensor input report start/stop and access events for ignition-aware workflows.
• Alarm and event reporting: overspeed, vibration/movement alarms, power-failure alerts, low-battery messages, and SOS events are pushed to Green-Gps for immediate notification.
• Fuel control / immobilizer: remote fuel cut-off via external relay allows Green-Gps-driven immobilization or recovery procedures.
• Telemetry continuity: local storage buffers data offline and retransmits when connectivity is restored, maintaining audit-ready records in Green-Gps.

Technical Overview

Use Cases

• Fleet management: real-time tracking, mileage statistics, and remote diagnostics to optimize routes, utilization, and maintenance scheduling.
• Anti-theft and recovery: SOS alarm, immobilizer (remote fuel cut-off), and movement/door alerts to secure vehicles and enable rapid recovery.
• Driver and vehicle safety: overspeed and vibration alarms help enforce safe driving behavior and detect incidents for immediate response.
• Remote control and monitoring: ACC/ignition detection and two-way voice allow dispatchers to verify vehicle status and communicate directly with drivers.
• Telematics continuity in poor coverage: onboard storage and blind-area retransmission ensure uninterrupted telemetry history for compliance and analysis.

Why Choose This Tracker with Green-Gps

The D22-4G delivers a balance of rugged hardware and the connectivity required for modern telemetry and fleet management workflows. As a Green-Gps compatible device, it feeds consistent real-time tracking data and event-based alarms into Green-Gps’s dashboards and reporting tools—helping fleets reduce theft risk, manage fuel control and immobilization processes, and maintain high data integrity through offline buffering. Its industrial waterproof design, integrated sensors, and two-way voice support make it a versatile choice for organizations that need reliable vehicle tracking, anti-theft features, and clear operational telemetry in one compact terminal.
