How to turn on/off the motion detection function of the Xiaomi Smart Doorbell 3S?

To turn on/off the motion detection function of the Xiaomi Smart Doorbell 3S, you can navigate to the [Mi Home/Xiaomi Home] APP >> select [Xiaomi Smart Doorbell 3S] >> tap the three-dot icon at the upper right corner >> [Motion detection settings] >> turn on/off the option as you need.
Note:
After completing the setup, configuring the motion detection only occurs on the APP. Therefore, after adjusting the settings, it is necessary to press the doorbell so that it can sync with the APP settings and operate according to the new configuration. Once the motion detection is turned off, the doorbell won't work when someone passes by.
