In and out of the house, the most frequent contact is the door lock. However, at present, the safety factor of traditional door locks is high or low, and the quality of products is uneven, which has great shortcomings in security and convenience. Intelligent door locks are different from traditional mechanical locks. They are more intelligent in user identification, safety and management, and have been widely welcomed by people since they came out.

　　For smart door locks, "safety" is the first premise. Bosch smart lock has the highest safety factor of "bank-level security" and adopts "five-fold elimination" to form active safety.

　　In order to prevent the prosthesis fingerprint, Bosch smart lock adopts the Swedish FPC living fingerprint sensor of the same paragraph of the bank to prevent false fingerprints from unlocking; Put an end to the "little black box" attack; With the configuration of 32-bit virtual password, the user can enter the 32-bit password at will, and the door can be opened only if there are 6 consecutive correct passwords, so as to prevent the password from being stolen; The lock body is equipped with multiple anti-theft sensors, which will give an alarm immediately in case of violent unlocking, so as to prevent violent lock picking; The mechanical safety bolt has a patent engineering endorsement to prevent babies and pets from unlocking and prevent cat eyes from unlocking.

　　Compared with traditional door locks, the security and intelligent performance of smart door locks have been improved, but some users are still worried that the door locks will be "maliciously attacked", and the "black box" incident transmitted by the internet has aggravated the users’ doubts. In fact, the "black box" is a high-frequency series resonant transformer with distributed parameters, which can generate strong electromagnetic pulses and attack the intelligent lock control system and the wire of the door lock motor, belonging to electromagnetic compatibility attacks. Some smart door locks on the market will be attacked only if there are defects in product design or because of cutting corners due to production costs.

　　Bosch has a "bank-level security smart fingerprint lock", which comprehensively enhances home security and creates an intelligent, convenient and safe home space for users.
