Xiaomi Smart Doorbell 3 – the latest smart doorbell with 2K resolution and Real-Time Monitoring system. The device has a 5200 mAh battery that provides 4 to 5 months of battery life. The device has a Doorstep Motion Notification function, so you can easily see what movement the smart doorbell detects. The smart call is equipped with a wide-angle camera, which gives you a broader view than standard cameras. The unit also includes a 24-hour smart surveillance system and a smart voice replacement system. The latter lets you change your voice during a conversation; in addition to your real voice, it lets you hear the person at the door speak in the voice of a clown or an old person. Of course, the bell has two communication levels and lets us communicate with the guest at the door. You can also manage the device with the Mi Home (Xiaomi Home) app.
