Eufy Camera Not Detecting Motion: 9 Fixes to Try First
Quick answer: If a Eufy camera is not detecting motion, check motion detection is enabled, raise sensitivity, adjust activity zones, confirm the camera is armed in the active mode, and test Wi-Fi signal at the camera location.
A Eufy camera can look perfectly normal in live view and still miss motion events. In most cases, the problem is not the lens — it is the mode, detection zone, sensitivity, battery-saving behavior, or the way the camera is mounted. This guide focuses on the fixes that are most likely to work before you reset the device, replace the battery, or contact support.
Fast diagnosis
| Symptom | Most likely cause | First thing to check |
| Live view works but no alerts | Detection mode or notification setting | Security mode and app notification permissions |
| Only misses people at night | Angle or low contrast | Move the camera lower or add light |
| Records late | Sleep/battery behavior | Sensitivity and detection distance |
| Works near router only | Weak Wi-Fi | Signal strength at install point |
Fixes to try first
1. Confirm the camera is armed in the current mode
Open the Eufy Security app and check the active security mode. If the camera is set to Disarmed, Home mode without recording, or a custom mode with motion disabled, it will not create events even if live view works.
2. Raise motion sensitivity gradually
Increase sensitivity one step at a time and test by walking across the camera view. Do not immediately set it to maximum; that can create false alerts from cars, shadows, and trees.
3. Rebuild activity zones
Delete the current activity zone and create it again around the area where people actually enter. A zone that is too narrow or too high can miss feet, faces, and bodies near the edge of the frame.
4. Check mounting angle
Battery cameras detect motion best when people move across the frame, not directly toward the camera. If the camera faces straight down a walkway, angle it slightly so motion crosses the sensor area.
5. Test Wi-Fi at the camera
Stand beside the camera with your phone connected to the same network. If signal is weak or unstable, move the router, add a mesh node, or reduce distance before assuming the camera is defective.
When the problem is probably not the device
Sometimes the Eufy camera gets blamed when the real issue is Wi-Fi range, router settings, weak batteries, app permissions, or a storage/subscription setting. If the issue started after a router change, app update, power outage, or subscription change, check those first.
Prevention tips
- Avoid aiming the camera at busy roads or trees.
- Keep firmware and app updated.
- Use local storage/home base health checks if available.
- Clean the lens and sensor area monthly.

FAQ
Why does my Eufy camera detect cars but not people?
The activity zone, human detection setting, or camera angle may be wrong. Rebuild the zone and test with a person walking across the frame.
Does low battery affect motion detection?
Yes. Battery-saving behavior can reduce responsiveness. Charge the camera and retest before replacing it.
Should I reset the camera first?
No. Check modes, zones, sensitivity, and Wi-Fi first. Reset only after basic settings fail.
