Smart door locks have gradually become the next outlet after smart speakers, ushering in a large-scale explosion stage.
According to data released by Statista, the global smart door lock market size was US$420 million in 2016 and US$1.28 billion in 2017. By 2019, the market size of smart door locks has risen to US$1.62 billion (approximately RMB 11.06 billion), a year-on-year increase. 24.62%. It is obvious from the data that the smart door lock market is still in a blue ocean.
In addition to the advantages of safety and convenience, smart door locks reduce the risk of burglary from "door sliding door picking", and can also be linked with other smart terminals in the house to enrich the smart home scene experience. Imagine that when you open the door, the entrance/living room lights will automatically turn on, the water heater will automatically turn on, and the curtains will automatically close... This kind of smart home system linkage cannot be completed by traditional mechanical door locks.

There are many excellent smart door lock products, each with its own characteristics. TCL K3 smart lock has AI human motion detection function, which is safe and guaranteed; Obi Zhongguang's 3D face-sweeping door lock has stable face recognition performance; Israel Wi-Charge's Alfred ML2 smart lock can be remotely wirelessly charged without replacement Battery; Securam Touch smart lock of Dongwu·Shian adopts internal vein recognition technology to improve the problem that the unlocking feature is easy to be stolen.
