On December 9, Xiaomi Youpin launched a new Berson smart door lock. It has a rear mainboard design and a crowdfunding price of 1999 yuan ($306). Officially called the “third generation” smart door lock, the first two generations of motherboards are outside the door. The first generation is an external clutch and the second is a central clutch. The main board of the third-generation smart door lock is inside the door with a rear clutch design.
The smart locks currently on the market usually have two structures, “front clutch” and “rear clutch”. After the front panel is damaged or separated from the door, you can directly use the tool to rotate the square shaft to unlock. After the “rear clutch” panel is damaged or separated from the door, it cannot be unlocked by rotating the square shaft with a tool.
This new Berson smart door lock uses a built-in clutch. The main board is located inside the door, forming a four-fold protection of the outer panel, door panel, lock body, and rear panel. Compared with the front panel clutch, it has a higher safety factor. Once the ordinary smart lock fails, the maintenance cost is high, and you even will have to return it to the factory. Berson uses a rear motherboard technology and a plug-in design. In case of electronic failure, it directly replaces the module and solves it in one step.
The Berson rear-clutch smart door lock supports six unlocking methods: fingerprint, password, Bluetooth, key, temporary password, and Mijia app. It collects fingerprints in 3D and has a resolution of up to 500DPI. The door lock can identify the shallow fingerprints of the elderly and children. It uses 4 AA batteries. This is enough for 365 days when you open/close the door twice a day. You will get notifications, if the power is less than 30%, and it can be used 100 times.
