1. Placeholder Password

The virtual password feature can prevent password eavesdropping. It allows for the input of any numbers before or after the door unlocking password, increasing its length and eliminating the risk of the password being peeked at and leaked. Therefore, when unlocking the door, multiple or groups of random numbers can be added before or after the correct password. As long as a continuous correct password exists within this set of data, the smart door lock can be unlocked.

2. Burglar Alarm Function

Equipped with anti-pick security-level induction modules, a high-decibel warning alarm will sound continuously upon detection of lock-picking attempts. In the event of abnormal door opening, external force damage, or even a slight misalignment of the door lock from the door, the intense alarm will attract the attention of passersby, effectively deterring any criminal activities by thieves.

3. Ultra-B grade for anti-theft door lock cores

The ultra-B grade lock cores feature a pillar-like design, with keys shaped as either a single-sided blade with internal milling slots or external milling slots. After extensive testing and research, these ultra-B grade lock cores offer a security anti-picking time of up to six hours. If intruders attempt forced entry, the lock cores automatically lock up, rendering them impossible to open. Typically, they are chosen by businesses, enterprises, or factories for their guaranteed security and reliability, giving users peace of mind. With the improvement of people's living standards, many households are also opting for these lock cores.
