Go to the [Mi Home/Xiaomi Home] APP >> select [Xiaomi Smart Doorbell 3S] >> tap the three-dot icon at the upper right corner >> [Doorbell settings] >> turn on/off [Removal alarm].
Note:
1. When the doorbell is being removed, the alarm will go off and will record and send a notification to the phone;
2. The setup is completed just on the APP, and the doorbell needs to be triggered by pressing the doorbell or by someone moving before the doorbell comes online again to take effect;
3. The prerequisite for the removal alarm to be effective is that the doorbell has power and the Internet is normal.
