Arlo Pro VMS4430 Motion Detection Does Not Work Properly

The camera’s motion detection may be turned off or set to a very low sensitivity level.

1. Open the Arlo app on your phone.
2. Tap Settings → My Devices.
3. Select your Arlo Pro VMS4430 camera.
4. Open the Mode or Rules section for that camera.
5. Check that Motion Detection is enabled.
6. Adjust the Motion Sensitivity slider to a higher level to improve detection.
7. Walk through the camera’s field of view to confirm the setting change works.

There could be obstructions blocking the view of motion.

1. Inspect the area around the camera for obstructions such as walls, furniture, plants, or glare.
2. Remove anything blocking the lens or narrowing the camera’s field of view.
3. Adjust the camera’s position so it faces the desired detection zone.
4. Aim for placing the camera 7–10 feet high and angle it slightly downward.
5. Walk through the area to test whether the camera now detects motion.

Restart and reset the camera if still not working.

1. Open the Arlo app and go to Device Settings for your camera.
2. Tap Restart to reboot the camera.
3. If the issue continues, press and hold the Reset button on the camera until the LED flashes amber.
4. Re-add the camera in the Arlo app when prompted.
5. If motion still doesn’t appear in the iPhone app, sign in to the Arlo web interface on a laptop.
6. Check the Library or Feed to see if motion is being recorded there.
7. If the web interface shows motion but the app does not, reinstall the Arlo app to resolve the app-specific issue.
