1. Check Your Motion Detection Settings and Sensitivity

One of the most common reasons your Aqara doorbell isn’t detecting motion is due to incorrect or overly restrictive settings. Motion detection is highly customizable, and small misconfigurations can drastically reduce its effectiveness.

Review Detection Zones in the Aqara App

Aqara doorbells allow you to define motion detection zones—specific areas in the camera’s field of view where motion should be monitored. If these zones are too narrow, misaligned, or accidentally disabled, your doorbell may ignore movement in critical areas.

• Open the Aqara Home app and navigate to your doorbell device.
• Go to Camera Settings > Motion Detection > Detection Zone.
• Ensure the detection zones cover high-traffic areas (e.g., the front walkway, porch, or driveway).
• Adjust the zones by dragging the corners to include relevant areas and exclude false triggers (like swaying trees or passing cars).

Example: A user noticed their doorbell wasn’t alerting them to deliveries. After checking the app, they found the detection zone was limited to a 2-foot area directly in front of the door. Expanding it to include the sidewalk restored motion alerts.

Adjust Sensitivity Levels

The sensitivity setting determines how easily the sensor detects motion. If it’s set too low, subtle movements (like a person walking slowly or a small pet) may go unnoticed.

• In the Aqara app, go to Camera Settings > Motion Detection > Sensitivity.
• Set sensitivity to Medium or High for optimal performance in most environments.
• For areas with frequent false alarms (e.g., near a busy street), use Medium to balance accuracy and responsiveness.

Tip: After changing sensitivity, test it by walking slowly toward the doorbell. If no alert appears within 5–10 seconds, increase sensitivity or adjust the detection zone.

Ensure Motion Detection Is Enabled

It might sound obvious, but double-check that motion detection is turned on. Sometimes, users accidentally disable it while adjusting privacy settings or after a firmware update.

• In the app, confirm that Motion Detection is toggled ON.
• Also verify that Notifications are enabled for motion events (Settings > Notifications > Motion Alerts).

2. Environmental Factors That Affect Motion Detection

Even with perfect settings, environmental conditions can interfere with your Aqara doorbell’s ability to detect motion. Understanding these factors helps you optimize placement and avoid common pitfalls.

Lighting Conditions and IR Interference

Aqara doorbells use infrared (IR) sensors and passive infrared (PIR) technology to detect motion. Poor lighting or IR interference can reduce accuracy.

• Low Light: In complete darkness, PIR sensors may struggle. Ensure ambient lighting (e.g., porch light) is on at night. Alternatively, use the doorbell’s built-in IR night vision (if available).
• Direct Sunlight: Intense sunlight, especially at sunrise or sunset, can cause false triggers or blind the sensor. Angle the doorbell slightly downward to avoid direct sun exposure.
• Nearby IR Sources: Other IR devices (e.g., security cameras, remote controls) can interfere. Keep the doorbell at least 10 feet from other IR emitters.

Example: A user’s doorbell stopped detecting motion at dusk. After installing a small LED porch light, motion alerts returned to normal.

Physical Obstructions and Placement

The doorbell’s field of view must be unobstructed. Common blockers include:

• Overgrown plants or shrubs
• Decorative items (e.g., wreaths, signs)
• Ice, snow, or debris (in winter)

To fix:

• Trim vegetation blocking the camera or sensor.
• Reposition decorative items to avoid covering the lens.
• Clear snow/ice regularly in cold climates.

Tip: The ideal mounting height is 4–5 feet above the ground, angled slightly downward (10–15 degrees) to cover the porch and walkway.

Weather-Related Issues

Extreme weather can temporarily affect performance:

• Heavy Rain/Fog: Water droplets on the lens can blur the image and trigger false alerts. Wipe the lens with a dry cloth after storms.
• High Humidity: Condensation inside the housing (rare) may require a desiccant pack. Contact Aqara support if persistent.

3. Power Supply and Connectivity Problems

Motion detection relies on stable power and a reliable Wi-Fi connection. Intermittent power or network issues can cause the doorbell to miss events or freeze.

Check Power Source and Voltage

Aqara doorbells require consistent power. If the voltage is too low, the device may enter a low-power state, disabling motion detection.

• Hardwired Models: Use a 16–24V AC transformer with at least 10VA power. Test voltage with a multimeter (should read 16–24V).
• Battery-Powered Models: Ensure batteries are charged above 20%. Low battery triggers power-saving mode, reducing sensor activity.

Example: A user’s doorbell stopped detecting motion after a power outage. The transformer’s output had dropped to 12V. Replacing it with a 20V/15VA transformer resolved the issue.

Wi-Fi Signal Strength and Interference

Weak or unstable Wi-Fi can delay alerts or prevent motion data from reaching the app.

• Use a Wi-Fi analyzer app (e.g., NetSpot) to check signal strength at the doorbell’s location. Aim for -65 dBm or stronger.
• Move your router closer or install a Wi-Fi extender/mesh system to improve coverage.
• Reduce interference by changing the router’s Wi-Fi channel (use channels 1, 6, or 11 for 2.4 GHz).

Tip: The Aqara app shows a Wi-Fi signal indicator. If it’s red or yellow, address connectivity issues first.

Router or Internet Outages

If your internet is down, the doorbell may still detect motion but can’t send alerts. Check:

• Router status lights
• ISP outages in your area
• Restart the router and doorbell if needed

4. Firmware, App, and Device Compatibility Issues

Outdated firmware, app bugs, or compatibility conflicts can break motion detection. Regular updates are crucial for performance and security.

Update Doorbell Firmware

Firmware updates often fix motion detection bugs and improve sensor algorithms.

• In the Aqara app, go to Device Settings > Firmware Update.
• Install any available updates. The doorbell must be powered and connected to Wi-Fi.

Note: Some updates require a factory reset. Back up settings if needed.

Update the Aqara Home App

An outdated app may not communicate properly with the doorbell.

• Update the app via your device’s app store (iOS/Android).
• Clear the app cache (Android: Settings > Apps > Aqara > Storage > Clear Cache).

Check for Compatibility Issues

Ensure your doorbell model is compatible with your phone’s OS and the Aqara ecosystem.

• Verify compatibility in the Aqara Support documentation.
• If using HomeKit or Alexa, check for integration updates.

Example: A user’s doorbell stopped detecting motion after a HomeKit update. Re-pairing the device in the Aqara app fixed the issue.

5. Hardware Malfunctions and Sensor Failures

If all software and environmental checks pass, the issue may be hardware-related. While rare, sensor or camera failures do occur.

Test the Camera and Sensor

Verify the hardware is functional:

• Open the live view in the app. If the video is blurry, dark, or frozen, the camera may be faulty.
• Cover the PIR sensor (small rectangular window) with your hand. The app should log a “sensor covered” event. If not, the sensor may be defective.

Reset the Doorbell

A factory reset can resolve hardware glitches:

• Press and hold the reset button (usually on the back) for 10–15 seconds until the LED flashes.
• Reconfigure the doorbell in the app.

Warning: This erases all settings. Use as a last resort.

Contact Aqara Support

If the doorbell still doesn’t detect motion after a reset:

• Check the warranty status (typically 1–2 years).
• Contact Aqara support with error logs and troubleshooting steps taken.
• Request a replacement if under warranty.
