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 from 4 to 5 months of battery life. The device has a Doorstep Motion Notification function, through which you will easily know what movement has been detected by the smart doorbell. The smart call is equipped with a wide-angle view camera, which allows us to perceive a more spatial image in contrast to standard view cameras. The unit also comes with a 24-hour smart surveillance system as well as a smart voice replacement system. The latter involves changing one's own voice during a conversation, and in addition to the real voice, it allows us to hear our voice by the person standing at the door either by the voice of a clown or by the voice of an old person. Of course, the bell has two levels of communication and allows us to communicate with the guest at the door. Of course, the device can be managed with the Mi Home (Xiaomi Home) application.
