Q20 4G SOS GPS Tracker
The Q20 4G SOS GPS Tracker is a compact, rugged personal tracker designed for children, elderly people, lone workers, pets, and valuable assets. Green-Gps compatible out of the box, the Q20 delivers dependable real-time tracking, configurable alarms, and two-way voice to improve safety and fleet management workflows without adding complexity to your monitoring platform.
The device balances long battery life with multi-network connectivity (4G LTE, 3G CDMA and 2G GSM) and GPS+WiFi+LBS hybrid positioning to speed fixes and increase accuracy in urban, indoor, and remote environments. With an IP67-rated enclosure, an oversized SOS button, fall/man-down detection, and buffered GPRS storage, the Q20 is built for continuous personal safety monitoring and anti-theft use cases where reliable telemetry and quick response matter.
Key Highlights
- Green-Gps compatible for seamless integration with real-time tracking dashboards and alerts.
- Multi-network connectivity (4G/3G/2G) ensures continuous location reporting across regions.
- GPS+WiFi+LBS hybrid positioning for faster fixes and improved location accuracy in challenging environments.
- Large SOS button, two-way voice (built-in mic and speaker), and call button for immediate contact and remote voice monitoring.
- Advanced safety sensors: 6-axis motion sensor with fall/tilt/man-down detection and vibration motor for user notifications.
- Waterproof, compact design with magnetic docking charging and up to about four days of operation on optimized settings.
- Buffer storage (GPRS/SMS) to retain position data when connectivity is temporarily unavailable.
How It Works with Green-Gps
When deployed with Green-Gps, the Q20 becomes a ready-made source of location and safety telemetry. The device reports position and status over the cellular network using configurable GPRS heartbeat intervals and can issue SMS alarm strings. Green-Gps ingests these feeds for real-time tracking, history route playback, and alarm notification delivery to web and mobile users.
- Real-time location and telemetry updates via the tracker’s GPRS reporting (buffered when offline).
- SOS alerts and two-way voice: immediate alarm delivery to Green-Gps with audio-enabled monitoring and callback for guardians or operators.
- Motion and fall/man-down detection: Green-Gps receives sensor-triggered alarms and can automate escalation rules or notifications.
- WiFi and LBS-assisted fixes improve indoor/urban tracking accuracy when GNSS reception is limited.
- Configurable alarms (geo-fence, low battery, motion/fall, SOS) and adjustable reporting intervals for optimized telemetry and data usage.
