Xiaomi Mijia Smart Door Lock 3D Fingerprint Password NFC Bluetooth Unlock - BLACK
Xiaomi Mijia smart door lock design
Like Mijia products, the appearance of Mijia smart door lock is simple and low-key style. The color matching is simple. The whole body is black in the non-operating state. The door handle and the lock hole cover are made of sandy texture materials.
The whole panel material of the smart door lock of Xiaomi is explosion-proof tempered glass made by acrylic IML technology. As a door lock, it is no blame. If the safety problem is neglected, the designer must be “Shi Lezhi”. The strength of the panel material of smart door lock of Xiaomi is comparable to the mainstream smart door lock in the market.
The design of UI interface of door lock is the same as that of ordinary smart door lock. The upper part of the panel is a digital password disk without operation hiding state. It can hide quickly after we input the password or touch it by mistake. Generally speaking, the design of hidden digital password disk has high security performance. It would be better if the display residence time can be set independently.
The fingerprint recognition area of the door lock is on the door handle. In order to better conform to the ergonomics, the smart door lock of Xiaomi adopts the elliptical groove design. The recognition area is large and the recognition rate is very accurate. In addition, Xiaomi smart door lock also uses sapphire material with Mohs hardness up to 9 to make fingerprint identification area cover. The cost performance is really good.
As for the key fingerprint opening of smart door lock, I can say very responsibly that it is the same as our usual door opening operation. When we grasp the door handle, the thumb will naturally be placed in the fingerprint area. While the fingerprint area can quickly identify fingerprints, we can press down the door handle to open the door. In addition, the bottom of the smart door lock is the USB emergency power jack and speaker. The emergency power jack is arranged in a place that is not conspicuous and hardly used in daily life.
The lower part of the outer part of the door lock is the keyhole, which is covered by a circular shell that is pushed up and rotated by a press. When opening a door with a key, we only need to press the circular shell with our thumb, and the key hole can be leaked by the homeopathic rotating shell. Inside the door lock is the anti-lock rotating knob of millet smart door lock, which is a set of almost all anti-theft doors. After entering the door, turning the button, and anti-locking the door, the security performance is higher.
What are the unlock ways of the Xiaomi Mijia smart door lock?
There are up to 5 ways to unlock the Xiaomi Mijia smart door lock, and they are: Password, keyhole, NFC, Bluetooth, fingerprint.
1. Living fingerprint unlocking
What I have to mention here is the fingerprint unlocking method of Xiaomi smart door lock. It is known that the door lock adopts the living fingerprint unlocking method. Most of the non-living fingerprint unlocking methods on the market use optical fingerprint unlocking, which leads to most unlocking methods being like those in the movie. Illegal persons or protagonists make fingerprint unlocking module by residual fingerprints, then press on the fingerprint unlocking area and open the fingerprint lock to achieve their own purposes.
But the smart door lock of Xiaomi adopts the technology of living fingerprint, so it can be recognized in many environments, such as dry fingerprint, cut, wet water and so on. Rubber and other simulated fingers can not pass it. Another advantage of living fingerprint is that even wet fingers can be quickly identified, and their safety and convenience are excellent.

The key hole can be seen by pressing down and sliding the cover plate.
