At present, there are various smart door locks in the market, and more and more functions. When we buy, what kind of fingerprint locks we face are what we need, so what details when buying smart door locks need special attention?
1. The core level of the lock: whether it is traditional locks or fingerprint locks, the security level of the lock core directly determines the security of the lock. The lock core on the market is divided into three levels of A \ B \ C. Many of the above are very low, and the most important thing is that the cost is also low. Some manufacturers will choose to use two types of lock cores for their profits, which need to be checked clearly when buying.
2. Fingerprint recognition: The core module of the fingerprint lock is fingerprint recognition. There are several fingerprint recognition modules. In fact, some modules do not support life fingerprint recognition. This is to support life fingerprint recognition, support the face -free recognition of face fingerprints of all ages, and accurately judge fingerprint depth, growth, dry skin, etc., high recognition rate, and can achieve financial security.
3. Password unlocking work: Some people ask, since the fingerprint recognition understands the lock function, why is there an additional password unlock? In fact, the password unlocking function is mainly to consider that there are friends/relatives/nanny at home, because these people are temporary people temporarily, because these people are temporary people are temporary people. Visitors do not need to add fingerprints every time, which will greatly reduce security. For example, when we let the visitors work outside, we directly tell them that the password is inconvenient. Unlock the password or take a friend home and do not want to let them know the password. You can use the dislocation password input to further improve the security level.
