Diagnosis
The AI detection settings are too restrictive or the camera's firmware needs an update.
How to Fix It
Verify detection settings. In the app, go to the camera's settings. Select 'Detection Settings'. Ensure 'Human' is toggled ON. Under 'Activity Zone', confirm the zone covers the walking path. Adjust the 'Sensitivity' slider for Human detection to 'High'.
If That Didn't Work
Update the camera's firmware. In the Eufy Security app, go to the device settings for the S340. Tap 'General' > 'Check for Updates'. Install any available firmware. This often improves AI algorithm accuracy.
Heads Up
The camera uses a combination of pixel movement and AI shape analysis. Loose clothing or people moving very quickly at the edge of the frame may occasionally not trigger the 'Human' tag, but will still be recorded as a 'Motion' event.
