2. If an update is available, tap Update Now and follow the prompts. Ensure the camera remains connected to power during the update.
3. For HomeBase 3 users, check Settings → System → Firmware Update to ensure all components are current.

Recalibrate Facial Recognition Training

Eufy's facial recognition system relies on training data to identify faces accurately. To recalibrate:

1. Open the eufy Security app and select the camera in question.
2. Go to Device Settings → Facial Recognition → Add New Face.
3. Capture 5-7 distinct images of the subject under different lighting conditions and angles. Avoid low-light environments or obstructions.
4. Save the new face data and test recognition by having the subject appear in front of the camera.

Configure Activity Zones for Precision

Eufy's Activity Zones allow you to define custom polygon-shaped areas for facial recognition. This prevents false detections and improves accuracy:

1. In the eufy Security app, select your camera and navigate to Device Settings → Activity Zones.
2. Tap + Add Zone and draw a polygon around the area where facial recognition should be triggered.
3. Ensure the zone includes the subject's full face and avoids shadows or glare. Save the zone and test its effectiveness.

Reset and Re-Pair the Camera

If facial recognition fails despite all efforts, a factory reset may be necessary. For Eufy Video Doorbell S330 models:

1. Locate the Sync button on the back of the device.
2. Press and hold it for 10 seconds until the indicator light begins pulsing rapidly.
3. Re-pair the camera via the eufy Security app by selecting Add Device → Doorbell → Eufy Video Doorbell S330.
4. Ensure your HomeBase is updated to the latest firmware before re-adding the camera.

For eufyCam S3 Pro users, press and hold the Sync button on the camera for 10-15 seconds until the LED begins flashing. Follow the same re-pairing steps as above.

Advanced Diagnostics and Factory Reset Procedures

Access Diagnostic Logs for In-Depth Analysis

If facial recognition issues persist, review diagnostic logs to identify patterns or errors:

1. Open the eufy Security app and go to Device Settings → Service Log.
2. Look for entries related to Facial Recognition or Connection Status. These logs may indicate firmware errors or connectivity issues.
3. Share the logs with Eufy support at https://service.eufy.com/uk for further assistance.

Perform a Factory Reset on HomeBase 3

For HomeBase 3 users experiencing persistent facial recognition problems, a factory reset may be required:

1. Locate the reset pinhole on the HomeBase 3.
2. Insert a paperclip and press and hold for 5-30 seconds until the LED flashes or beeps.
3. Re-pair all connected cameras via the eufy Security app and ensure firmware is up to date.

Root Causes of Eufy Facial Recognition Failures

Eufy facial recognition issues often stem from a combination of environmental, technical, and user-related factors. Poor lighting conditions, especially in low-light or high-contrast environments, can hinder accurate face detection. Ensure your camera is positioned to capture faces in well-lit areas, avoiding direct sunlight or shadows.

Outdated firmware is another common culprit. Eufy regularly releases updates to improve facial recognition accuracy and fix bugs. Always check for updates in the eufy Security app under Device Settings → About Device → Firmware Status.

Incorrect configuration of Activity Zones can also lead to recognition failures. If zones are too narrow or exclude key areas, the camera may miss faces entirely. Recalibrate zones to ensure they cover the full detection range.

Finally, hardware degradation over time can impact performance. Battery-powered cameras may fail to capture faces if the battery is low. Wired models should have a stable power supply, with a transformer voltage of 16-24V AC at the junction box.

Prevention and Long-Term Care for Eufy Facial Recognition

Maintaining your Eufy camera's facial recognition system requires regular attention to settings, firmware, and environmental factors. Here are best practices to prevent future issues:

• Schedule Firmware Updates: Enable automatic updates in the eufy Security app under Settings → System → Firmware Update. This ensures your camera always runs the latest software.

• Optimise Lighting Conditions: Position cameras to avoid glare, shadows, or low-light environments. Use external lighting if necessary to improve face visibility.

• Monitor Battery Levels: For battery-powered models, charge the camera fully when the battery drops below 20%. Replace batteries if degradation is suspected after 300-500 charge cycles.

• Recalibrate Periodically: Re-add faces in the eufy Security app every 6-12 months to maintain accuracy. This is especially important if family members change appearance significantly.

• Use Eufy's Activity Zones: Configure zones to focus facial recognition on key areas, reducing false positives and improving performance.

Full disclosure: we built scOS to address exactly this—the frustration of cameras that depend on facial recognition to function reliably. scOS uses permanently powered cameras connected via Ethernet, ensuring consistent performance without battery or firmware limitations.
