What lock is safer for household security doors?

In the best times, there will be a group of people who want to get something for nothing and try their best to steal other people's property. -"Opening the door at night" can reflect the per capita quality of the current society, but it does not mean that the awareness of family safety can be diluted. As the first line of defense, micro-shield technology door lock has been playing an important role in protecting people and money. From the "latch" in Yangshao culture period to the "three-spring lock" in Han Dynasty, the "Citi lock" in Ming and Qing Dynasties, the "blade lock" in18th century, and then to the cylindrical "marble lock" invented by American Nanas Yale in 1848 (later improved by Nanas Yale), mankind has entered the modern era.

In the lock history of 5,000 years, every improvement is not only a change in appearance, but also an emphasis on security. The modern lock of Weidun Technology is mainly composed of a lock core and a lock body, and the security level of the lock core directly represents whether the door lock can be easily opened by others.

Modern lock anti-theft lock core is divided into three categories: A, B and C (Super B).

Anti-destructive opening time of Class A lock cylinder > 15 minutes, anti-technical opening time > 1 minute;

The anti-destructive opening time of class B lock cylinder is more than 30 minutes, and the anti-technical opening time is more than 5 minutes;

The anti-technology opening time of C-class (super B-class) anti-theft lock cylinder is more than 4 hours.

① Class A lock core belongs to common anti-theft, and it mainly adopts one-word or cross key. The internal structure of class A lock core is relatively simple, and the change only lies in the change of marble and the few shallow marble grooves, so the mutual opening rate of this lock core is extremely high; -Mechanical door lock

② The difference between Class B keys and Class A keys lies in a row of irregular curved lines. The lock cores are divided into three types: computer double-row lock cores, double-sided blade lock cores and double-row crescent lock cores. -Mechanical door lock

③ The type of Class C lock core is side column lock core, and its internal structure is double-row blades and V-shaped side column lock. If it is forcibly opened with a tool, the inside of the lock core will be damaged, and it will explode and lock. -Micro-shield technology electronic intelligent lock

-Above, choose electronic intelligent lock, the safety factor of lock core is higher than that of traditional mechanical lock.

Then, when we figure out the difference between lock cores, how to choose an electronic smart lock?

At present, the mainstream unlocking methods of smart locks are divided into "fingerprint identification" and "finger vein identification"

Fingerprint identification: through the direct contact between finger skin and equipment collector, the surface texture information of finger is obtained;

Finger vein recognition: Fingers are irradiated by light with a specific wavelength, and the principle of imaging is that flowing blood can absorb light with a specific wavelength.

By comparison, we know that the fingerprint lock is verified by using the fingerprint on the finger surface as identity information. In this way, fingerprints cannot be recognized normally because of peeling, wear, oil stains, soaking in water and other factors. Microshielding technology refers to veins, that is, veins and blood vessels in fingers (the irradiation process will not cause any harm to human body). This method will not be affected by any skin surface factors, and it belongs to a more advanced biometric technology than fingerprints.

Summary: When you live with old people (with seriously worn fingerprints) and children (with shallow fingerprints), it is not recommended to buy fingerprint locks, and you can directly choose the finger vein locks of Micro Shield Technology. After all, no one wants old people and children to be locked out.
