▶ FAQ

Q1: How does the FDS315 detect falls without a camera?
A: The FDS315 uses 60GHz millimeter-wave radar technology to detect human presence, movement, posture changes, and fall events. Unlike camera-based systems, it operates without capturing images or videos, providing a privacy-friendly solution for elderly care environments.

Q2: Is the FDS315 suitable for nursing homes and assisted living facilities?
A: Yes. The FDS315 is designed for elderly care applications such as nursing homes, assisted living facilities, rehabilitation centers, and senior apartments. It provides real-time fall detection, out-of-bed monitoring, and occupancy sensing to help caregivers respond more quickly to potential incidents.

Q3: What is the recommended installation height for the FDS315?
A: For optimal detection performance, the FDS315 should be wall-mounted at a height of approximately 1.6–1.7 meters. Proper installation helps ensure accurate monitoring of occupancy, movement, and fall events within the coverage area.

Q4: Can the FDS315 detect breathing during sleep?
A: Yes. The FDS315 can monitor breathing rate during sleep using radar sensing technology. The breathing detection range is approximately 7–45 breaths per minute, and the user should remain in bed for more than 40 seconds for accurate detection.

Q5: Can the FDS315 work with Zigbee2MQTT and Home Assistant?
A: Yes. The FDS315 supports ZigBee 3.0 and can work with Zigbee2MQTT and Home Assistant for flexible integration into elderly monitoring and smart care systems. It can also be integrated with compatible ZigBee gateways and third-party platforms, making it suitable for system integrators and customized healthcare IoT projects.

Q6: Why Not a Traditional Motion Sensor?
A: Unlike standard PIR motion sensors that rely on movement, the FDS315 detects micro-presence and posture changes, making it suitable for healthcare and elderly monitoring where users may remain still for long periods.
