Motion detection can work with night vision on hidden cameras. In fact, many night vision hidden cameras come with motion sensors that can detect movement even in low light or complete darkness. When motion is detected, the camera can automatically switch to night vision mode and start recording. This feature can be particularly useful for surveillance purposes, as it can help conserve storage space and battery life by only recording when motion is detected. Additionally, some hidden cameras with night vision and motion detection also have the ability to send notifications to a mobile device when motion is detected, allowing for real-time monitoring and response.
