Last November, in an article where we announced the Xiaomi news, we were also writing about this Smart Ring, which was listed on the crowdfunding platform at the time. Meanwhile, he seems to have managed to raise the money needed to produce, and has recently joined the Chinese shops. Xiaomi FJ02MLWJ (Xiaomi Zero AI Face Identification Video Doorbell Set)is a ringtone for the apartment with some Smart features.
Virtually outside, where the visitor button is, a room is integrated, and when someone approaches the 3 meters from the door of the house, it automatically sends a notification to the phone with a video clip of a few seconds attached. Using artificial intelligence, she knows when the door is a family member or an unknown person. I do not know how much artificial intelligence will work, I find it more helpful to get a clip through which you can quickly see who is at the door, whether you are at home or not.
Also, when someone rings the ring, you will receive instant notification on your phone, and you will be able to see and talk in real-time through the app (use the Mi Home app). The ringer works with 4 batteries that guarantee an autonomy of up to 6 months. If someone tries to steal the transmitter, it will trigger an alarm to the home receiver as well as the phone application to be able to intervene quickly.
The ringer comes in a package with a transmitter (room to be installed out) and a receiver (a device to be plugged in) and the maximum operating distance between the two is up to 50 meters. However, the manufacturer does not specify whether the transmitter is resistant to humidity or water, so I do not know if it can be used at home, and for this reason I could say that it is intended only for those living in the apartment.
