  • FAQ

    What causes a motion sensor to go off?

    A motion sensor alarm is triggered by movement within its detection zone, often caused by people, pets, shifting shadows, or environmental changes like heat or airflow. In security systems, infrared or radar sensors detect changes in temperature or motion, which can activate outside motion sensor alarms, lights, or camera recordings.

    Why does my motion sensor keep beeping?

    Constant beeping from a motion sensor may indicate a low battery, connectivity issues, or that the sensor is detecting frequent movement. On eufy indoor or outdoor motion sensor alarm systems, beeping can also signal maintenance alerts, such as full storage or device calibration. Checking the app notifications usually helps identify and resolve the issue quickly.

    What is the difference between a motion sensor and a motion detector?

    The terms are often used interchangeably, but technically, a motion sensor is the component that senses movement, while a motion detector is the device that houses the sensor and may include processing features. In eufy security cameras, motion detectors combine alarm sensor motion with AI to detect and classify motion events intelligently.
