Fingerprint password lock, not the more functions the better!

APP functions, Bluetooth connections, and password fingerprints should not be used by the elderly. In the final analysis, a fingerprint lock is a lock. The lock core, lock body and bracket must be excellent, and then it is the turn of the smart functions.

1. The lock cylinder must be a key that reaches level B or above. Let the seller unlock the fingerprint lock cylinder. If it cannot be taken out, ask the seller to remove the front panel and observe. This kind of fake insert core is easy for thieves to pry open;

2. The lock body and side protruding tongue should be made of precision-cast 304 stainless steel. The main anti-theft tongue should be at least HRC55 with an ordinary saw blade. If there is no anti-theft inspection report issued by the Ministry of Public Security, skip it!

3. The bracket must be built-in. Once the panel is removed, the core components will be nakedly exposed to the police. The door can be opened by energizing the motor;

4. The more intelligent functions there are, the more loopholes there will be. If the elderly have poor memory, add a fingerprint recognition or IC card. If the cleaning service comes to your door, just set a temporary password.
