How to choose a safe face recognition lock?　

1. Whether to prevent card opening

Many face locks design the lock tongue into an arc shape for the sake of beauty, but this kind of lock tongue has a loophole. If you forget to reverse the lock one day and don't punch out the main lock tongue, this kind of face recognition lock can push the lock tongue back directly by pushing the card hard, and then the door will open automatically. So when we buy face lock, we must see what shape the lock tongue is, and never buy the smooth arc lock tongue.

2. Is the material of lock cylinder solid

In addition to the level of the lock cylinder, the material of the lock cylinder is also an important standard for the safety of the face recognition lock. If the face lock is made of iron, it is easy to be violently damaged by tools, and then directly enter the door. But choose copper lock cylinder or zinc alloy lock cylinder, then the security level of this lock is completely different, thieves to force to pry the lock, it is estimated to take several hours.

3. Lock cylinder class

The lock cylinder level is divided into a, B and Super B (C level). C level lock cylinder can be said to be the standard configuration of face recognition lock now. If it is not C level lock cylinder, the face lock can not hold for more than 20 minutes when the thief technology unlocks, while C level lock cylinder can hold for more than 240 minutes. If the thieves use the forced opening method, the lock cylinder will be automatically jammed, resulting in a situation that cannot be opened.

4. Anti lock alarm

When thieves see the face recognition lock, they usually won't pry the lock tongue, they will choose to pry the panel, so at this time, we need the face lock to have an anti prying alarm, that is, a pressure sensor. When the face recognition lock senses the lock prying behavior, it will give a loud alarm, and when the user is not at home, the face lock can also send remote alarm information, which is the best.
