At present, smart locks on the market are mainly divided into optical fingerprint identification and semiconductor biological living fingerprint identification. Compared with optical fingerprint, living fingerprint has higher sensitivity and recognition accuracy.

Whether it is a traditional door lock or a smart door lock, the key to its protection ability lies in the lock core. At present, the classification of lock cores in the market can be described as various, including A-level, B-level and C-level.

According to the standard of Mechanical Anti-theft Lock, the opening time of three levels of lock core anti-theft technology is not less than 1 minute, 5 minutes and 10 minutes respectively.

When they see the lock of the C-class lock core, they choose to give up directly, because the long unlocking process greatly increases the possibility of being discovered. Therefore, the door lock products of Class A and Class B lock cores are the "hardest hit areas" for theft. When choosing smart door locks, you need to choose Class C lock cores first.
Comfortable and safe unlocking experience
Yunmi Internet Smart Door Lock Link supports five unlocking methods, including fingerprint unlocking, password unlocking, IC card unlocking, APP remote unlocking and key unlocking, among which fingerprint unlocking is undoubtedly the most convenient.

It should be noted that when the password is unlocked, it supports the protection function of 20-digit virtual password. At ordinary times, we should try our best to develop the habit of inputting virtual password, which can prevent voyeurism. In addition, people are worried about the incident of "black box" cracking the smart lock. According to professionals, the black box uses a transformer to boost the voltage to form a strong electromagnetic pulse, which interferes with the capacitor components of the smart lock and makes the lock run automatically to crack. In order to ensure family safety more comprehensively, it is obviously not enough to consider only the security level of the lock core. This product is specially designed for electromagnetic protection against this situation, which can greatly reduce the influence of electromagnetic radiation on smart locks and protect them from "black box" attacks.
