If your Arlo camera isn't detecting motion, try these steps to fix the issue: First, ensure your camera's motion detection settings are correctly configured in the Arlo app. Check if the camera's field of view is obstructed or if the motion sensitivity needs adjustment. Make sure the firmware is up-to-date. If the problem persists, restart the camera and router. For further assistance, contact Arlo support at +1-800-857-0779.
