1、 Price butcher comes on the stage, automatic intelligent door lock will marry down the price of 1699 yuan

Nowadays, smart door locks have gradually entered thousands of households, and more and more families have begun to replace their traditional locks with smart locks.

From a few unlocking methods to the popularity of living fingerprint unlocking methods, the function and shape of intelligent door locks have been completely changed in recent years.

At the same time, the price of the first appointment has been reduced to the limit level of 1699 yuan (the retail price of the product is 1799 yuan, and the deposit is 100 yuan to 200 yuan)


After several days of installing and experiencing the lock, Kuai tech found that the so-called full-automatic means that the latch will automatically retract after the fingerprint verification is passed when the door is opened, and the lock will be automatically locked within 0.8 seconds when the door is closed, eliminating the action of rotating / pushing the handle when opening and closing the door.

According to Xiaomi's official statement, the internal mechanism of automatic door lock is a power system composed of linear driving force, planetary gear deceleration, micro motor power, state perception and other components.
