eufyCam S3 Pro Not Detecting Motion? Here’s How to Fix It
Your eufyCam S3 Pro triggers alerts and recordings from motion detection. Missed alerts usually come down to a setting, a detection zone, or placement.
What This Problem Means
If your eufyCam S3 Pro is showing this fault, working through the checks below in order resolves it in the large majority of cases. Each step is safe to try yourself and follows eufy’s official guidance.
Common Symptoms
- No motion notifications
- Events missed
- No clips after movement
- Only some movement detected
Safe Checks You Can Try
1. Check detection is on
In Camera Settings, make sure motion detection and notifications are switched on, and that the camera isn’t set to Disarmed mode.
2. Set the detection type
eufy lets you choose what triggers recording (e.g. humans only). Make sure your chosen type matches what you want to catch.
3. Raise the sensitivity
Increase motion sensitivity so smaller or more distant movements register.
4. Check Activity Zones
Make sure the area you care about isn’t excluded by a detection zone.
5. Position for crossing motion
eufy’s PIR sensor detects movement that crosses the view better than movement coming straight at it. Mount within about 8–10m of where people pass, and avoid pointing through glass.
