Diagnosis
The Activity Zone or Motion Sensitivity settings in the Eufy Security app are either too restrictive or the sensor is physically obstructed.
How to Fix It
Open the app and immediately reconfigure the detection zone. 1) Device Settings > Detection Settings > Activity Zone. 2) Draw a zone covering the entire area where you need detection. 3) Set Motion Sensitivity to at least 5. 4) Ensure 'Human Only' detection is ON if you want to reduce other triggers.
If That Didn't Work
The dual-lens design means one lens is wide-angle, one is telephoto. Check that the primary detection lens (the main, larger one) isn’t blocked by a spider web, dirt, or a bug. Wipe it gently with a microfiber cloth.
Heads Up
The camera prioritizes detecting motion crossing the zone, not motion toward the camera. Angle the floodlight so the detection path is perpendicular to the typical walking path for best results.
