Eufy Video Doorbell Dual motion alerts not working
Missing motion notifications from your Eufy Video Doorbell Dual can leave you unaware of visitors, deliveries, or potential security concerns at your front door. This issue typically stems from app notification settings, motion detection configuration, power-related problems, or firmware bugs. The good news is that most cases of Eufy Video Doorbell Dual motion alerts not working can be resolved with systematic troubleshooting. Follow this guide to restore reliable motion detection and get your alerts working again.
Check Notification and Motion Detection Settings
Before investigating hardware issues, verify that your software settings are configured correctly. The Eufy Security app contains multiple layers of controls that can silently suppress motion alerts.
1
Enable Motion Detection in the Eufy Security App: Open the Eufy Security app, select your Video Doorbell Dual, tap the gear icon for Device Settings, then navigate to Motion Detection. Ensure the main Motion Detection toggle is turned ON. Set your Detection Type to "Human Only" or "All Motion" based on your preference, and verify the Detection Sensitivity is above 0 (we recommend 4-6 for most homes).
2
Verify Activity Zones Are Properly Configured: Within Motion Detection settings, tap Activity Zone. If you've created custom zones, confirm they're positioned over areas where motion actually occurs. Overly restrictive or misplaced zones can cause legitimate motion events to be ignored. Consider temporarily deleting all zones to test if alerts resume, then recreate them more carefully.
3
Check Phone Notification Permissions: On your smartphone, go to Settings > Notifications > Eufy Security and ensure notifications are allowed. For iPhone users, verify that Focus modes or Do Not Disturb aren't blocking the app. Android users should check that battery optimization isn't restricting background activity for the Eufy Security app, as this can prevent push notifications from arriving.
Address Power and Connectivity Problems
The Eufy Video Doorbell Dual requires stable power and a strong Wi-Fi connection to process and transmit motion events. Instability in either area can cause Eufy Video Doorbell Dual motion alerts not working intermittently or completely.
4
Confirm Adequate Power Supply: For wired installations, check that your transformer delivers 16-24V AC at 30VA minimum. Low voltage causes the doorbell to disable power-hungry features like motion detection to preserve basic functionality. For battery-powered operation, ensure charge is above 20%. Navigate to Device Settings > Power Manager and disable "Optimal Battery Life" mode if active, as this aggressively reduces motion detection frequency.
5
Test and Improve Wi-Fi Signal Strength: In the Eufy Security app, check your doorbell's signal strength indicator (found in Device Settings > Wi-Fi Connection). One or two bars indicates a weak signal. Move your Wi-Fi router closer, eliminate physical obstructions, or install a Wi-Fi extender near your front door. Weak signal causes delayed or dropped motion events that never reach your phone as alerts.
6
Restart Your Doorbell and HomeBase: If you use a HomeBase, unplug it for 30 seconds, then reconnect. For the doorbell itself, remove it from the mounting bracket (battery models) or turn off power at the breaker for 60 seconds (wired models). This clears temporary firmware glitches that commonly disrupt motion alert processing. After restart, wait 2-3 minutes for full reconnection before testing motion detection by walking in front of the camera.
⚠️ Warning: Do not perform a factory reset on your Eufy Video Doorbell Dual unless absolutely necessary. Resetting erases all settings, recorded footage, and requires complete reconfiguration including re-adding users and redefining activity zones. Exhaust all other troubleshooting steps first, and ensure you have access to your Wi-Fi password and Eufy account credentials before proceeding.
Update Firmware and Verify App Functionality
Outdated firmware frequently causes Eufy Video Doorbell Dual motion alerts not working due to known bugs. Eufy periodically releases patches addressing motion detection and notification reliability.
7
Install Pending Firmware Updates: Open the Eufy Security app, select your doorbell, and check Device Settings > About Device for available updates. If an update appears, connect your phone to Wi-Fi (not cellular) and initiate installation. Keep the app open during the 5-10 minute update process. The doorbell will temporarily go offline and reboot automatically when complete.
8
Reinstall the Eufy Security App: If settings appear correct but alerts still fail, delete and reinstall the app entirely. This resolves corrupted local data that can interfere with notification delivery. After reinstalling, log in with your Eufy account, re-enable notifications when prompted, and test motion detection by creating movement in the camera's field of view during daylight hours.
Still Need Help With Your Eufy Device?
If these steps didn't resolve the motion alerts not working issue, our certified technicians can help.
Why do I get motion alerts for cars but not people?
This indicates your Detection Type is likely set to "All Motion" with high sensitivity, while human detection specifically may be failing. Switch to "Human Only" detection, or if already using that setting, lower the sensitivity slightly and ensure your doorbell firmware is updated. Poor lighting at night can also cause the AI to miss human figures while detecting larger vehicle movements.
Can extreme weather cause motion alerts to stop working?
Yes. Temperatures below -4°F (-20°C) or above 122°F (50°C) can affect the doorbell's PIR sensor and processor performance. Heavy rain, snow, or direct sunlight glare can also trigger false negatives by obscuring the lens or overwhelming the sensor. Install a weather-resistant cover if your doorbell faces direct exposure, and verify operation returns to normal when conditions moderate.
How do I know if my motion alerts are working without waiting for actual visitors?
Use the Eufy Security app's live view during testing. Walk directly across your doorbell's field of view at various distances (5, 10, and 15 feet). A small motion detection icon should appear in the live view feed when triggered. Check the Events tab immediately afterward—successful detections appear here within 30 seconds even if push notifications fail separately.
