EV-04 Personal 4G GPS Tracker Pendant
The EV-04 is a compact, ALTAGAMA GPS compatible GPS tracker pendant engineered for dependable personal protection and remote patient monitoring. Built on an MTK platform and supporting multi-band 4G with fallback to 3G/2G, this lightweight wearable combines one-button SOS, highly sensitive fall detection, two-way calling, and multiple positioning technologies so caregivers and monitoring services receive timely, accurate alerts and location data.
The EV-04 integrates seamlessly with the ALTAGAMA GPS platform for real-time tracking, audible alerts, and centralized telemetry. Its IP67 water resistance, soft-touch housing (≈53 g), and optional Bluetooth beacons for improved indoor accuracy make it a practical solution for seniors, patients, and lone workers who need an always-on SOS device paired with ALTAGAMA GPS monitoring and reporting tools.
Key Highlights
- ALTAGAMA GPS compatible GPS tracker pendant for instant SOS reporting and centralized monitoring.
- One-button SOS with two-way calling (integrated speaker & microphone) for direct voice communication during emergencies.
- Highly sensitive fall detection (reported >70% accuracy) plus automatic SOS triggering and voice prompts/TTS to guide users.
- Multi-tech location: GPS, Wi‑Fi, BLE Beacon and LBS with automatic updates as frequently as every 10 seconds during SOS.
- Compact, lightweight IP67 design with LED indicators, dedicated charging base (Bluetooth 5.0) and drop-in charging convenience.
- Supports Bluetooth pairing with medical devices for remote patient monitoring (RPM) without requiring a separate app on the user’s phone.
- FOTA (remote firmware upgrades), medication reminders, Web + iOS/Android platform and rebranding support for commercial deployments.
How It Works with ALTAGAMA GPS
When integrated with ALTAGAMA GPS, the EV-04 becomes a purpose-built personal GPS tracker that feeds location and event telemetry into ALTAGAMA GPS’s real-time dashboard and alerting engine. Whether used in a monitored service or self-monitoring mode, ALTAGAMA GPS displays live position, event history, and device health while forwarding SOS calls and notifications to predefined contacts or monitoring centers.
- Real-time location and telemetry updates delivered to ALTAGAMA GPS, including live tracking during SOS events (updates as often as every 10 seconds).
- Automatic fall detection and one-button SOS events forwarded to ALTAGAMA GPS for immediate action by caregivers or monitoring centers.
- Two-way voice calls initiated from the device, with ALTAGAMA GPS logging call events and status changes for audit and follow-up.
- Bluetooth sensors and BLE beacons for enhanced indoor positioning and optional pairing with medical devices to stream RPM data into ALTAGAMA GPS without extra user apps.
- Device management and firmware updates (FOTA) coordinated through ALTAGAMA GPS-compatible workflows for remote maintenance.

Use Cases
- Personal protection for seniors and elderly family members — SOS button, fall detection and live GPS tracking for rapid response.
- Remote patient monitoring (RPM) — BLE pairing with medical devices and medication reminders, with telemetric data accessible via ALTAGAMA GPS.
- Lone worker safety — lightweight SOS pendant that provides voice communication and location to ALTAGAMA GPS for rapid incident handling.
- Home care and assisted living — optional BLE beacons improve indoor accuracy and charging base with extra SOS support simplifies daily use.
Why Choose This Tracker with ALTAGAMA GPS
The EV-04 delivers a clear value proposition when paired with ALTAGAMA GPS: rapid, reliable real-time tracking and event telemetry in a compact, user-friendly pendant. Integration with ALTAGAMA GPS enables centralized incident handling, auditing of SOS and call logs, and remote device management via FOTA. Its Bluetooth sensor support and BLE beacon options extend capabilities for indoor accuracy and RPM without forcing caregivers or users to manage separate apps.
While the EV-04 is optimized for personal safety, healthcare and lone-worker protection rather than fleet management or vehicle telemetry, its ALTAGAMA GPS compatibility means organizations can incorporate the EV-04 into broader monitoring portfolios. Note that vehicle-specific features like fuel monitoring, ignition sensing or immobilizer control are not part of this device’s feature set—choose EV-04 with ALTAGAMA GPS when the priority is personal GPS tracking, two-way emergency voice, fall detection and medical telemetry.
