According to the data released by the National Lock Center, by the end of June 2018, more than 1500 manufacturers of intelligent door locks in China had sold 21 million sets annually. However, due to the lack of national mandatory safety standards, and many brands are not manufacturers in fact, most of them are OEM production, so the quality of intelligent door locks is not uniform. Even under such circumstances, the total sales of head brands account for more than 60% of the total sales in 2018. From this, it can be seen that the products that are recognized by users are still conscientious products and conscientious market-making. Head brand side, and OEM products due to the lack of brand operation in all aspects, it is difficult to get market recognition, product quality is also worrying.
In 2018, Tesla coil was in the limelight at the 9th China (Yongkang) International Door Industry Exposition. The fact that intelligent door locks were opened in seconds was fermenting on the Internet. This made ordinary consumers doubt the security of intelligent door locks.

Put on the agenda, then is smart door lock safe after all?
The so-called “small black box” which can open the intelligent lock in seconds is equipped with a button. When the button is pressed, an instantaneous magnetic field will be generated.
