At present, basically all smart door lock products have a backup key unlocking method, and fingerprint identification lock products are no exception. They must also be equipped with a secure anti-theft lock core. Which type of anti-theft lock core is better for fingerprint identification locks?
The anti-theft lock cylinders currently used in the market can be basically divided into three levels, namely A-level, B-level, and super B-level (also known as C-level), while the "Mechanical Lock Standard" has only classified A, B level, while the super B level is an enhanced security version developed by some door lock manufacturers, with good security performance!
A-level lock core: The internal structure of the A-level lock core is actually very simple. It is limited to the change of marbles. The marble grooves are small and shallow. The structure of the marbles is mostly single-row marbles or cross locks. It can be opened in minutes. It is an old door lock structure and the cost is relatively low! Class B lock cylinder:
B-level lock cylinder: The difference from A-level is that there is an extra row of curved lines on the key surface, which increases the difficulty of unlocking. Type B lock cylinders are mainly divided into three types: computer double-row lock cylinders, double-row crescent lock cylinders, and double-sided blade lock cylinders. , Better security!
Super B-level lock (C-level) lock core: The type of lock core is a side pillar lock core, which uses double-row blades and V-shaped side pillar locks inside. The mutual opening rate is zero. And even if you use a strong twisting tool to open the lock cylinder, the inside of the lock cylinder will explode and lock to death, which can cope with various technical unlocking by thieves, and it is very safe!
In terms of the security level of the anti-theft lock core, the fingerprint identification lock is a C-level lock core. Although the cost and price will be increased, this can provide good security for door locks and bring better security!
