Fingerprint lock manufacturers from the lock cylinder to discuss the security of intelligent fingerprint locks

As we all know, the corresponding production process and lock performance varies from period to period, and in the objective context of the gradual withdrawal of B-class locks from the market and the widespread popularity of C-class, the security effect in various application scenarios is also uneven, in contrast, the use of smart locks in various cases, whether the convenience of use or application security has been substantially improved, which also objectively reflects the mature intelligent security model The practical value of.

　　Many people may say that smart locks provide fingerprints, passwords, cards and other ways to open the lock plus a keyhole to open the lock security is greatly reduced. But this is actually a big misunderstanding, the most important of the lock anti-theft function is the lock core, then we will explore the three types of lock cores that exist on the market; the types of lock cores that exist on the market now are A-grade, B-grade, C-grade lock cores. Ordinary mechanical locks are standard with A-class lock core, burglar-proof locks are standard with B-class lock core, and smart locks are now crossing from standard B-class lock core to standard C-class lock core.

　　Now we will analyze the security of the C, B, A, grade lock cores respectively.

　　C-class locks.

　　Currently on the market is more secure C-class lock cylinder, using a double row, computer, composite curve groove patented key, 270 minutes can not be technically opened. Among them, the C-class lock cylinder financial industry use more, less civilian.

　　B-class locks.

　　B-level lock key for flat keys, with double-row bullet slot, different from the A-class lock is the key face more rows of curved irregular lines. The main type of lock core for three kinds, computer double-row lock core, double-row crescent lock core, double-sided blade lock core. Anti-technical opening time within 5 minutes, the mutual opening rate is high. The lock core can be opened within 1 minute by strong twisting tools.

　　B-class lock core unlocking time: B-class lock core professionals more than 5 minutes, 120 minutes or less to open.

　　A-grade locks.

　　Currently on the market A-class security lock key mainly a word key and cross key. A-class lock core internal structure is very simple, limited to the change of the bullet, the bullet slot less and shallow. Anti-technical opening time within 1 minute, the mutual opening rate is very high. The bullet structure is a single row of bullets or cross lock.

　　Once the relevant industry insiders did experiments in the field, it took 41 seconds to open the lock of the resident's home, which is what we call a class A lock, this lock can be opened in a much shorter period of time, in ten seconds to open.

　　After a large number of investigations concluded that 90% of thieves fail to open the lock in a minute will actively give up, and thieves open A-class locks can generally open in a dozen seconds, so that the A-class lock security factor is lower.

　　The three levels of unlocking time varies, the longer the time, the higher the security factor, the lower the likelihood of theft.
