Beijing, December 2, CCTV News According to the News Hyperlink of the Voice of China of China, the release of the movie Door Lock recently attracted attention to the safety of door locks. In the film, the residence of the lone hero is broken into by others. What lock can lock the safety? Is anti-theft door "to guard against gentlemen, not villains"? What should we pay attention to when using smart door locks?

What does the security door guard against?

The material of security door panel mainly includes iron, aluminum alloy, stainless steel, copper, etc. The door panel made of aluminum alloy or stainless steel is relatively stronger in structure. However, Zheng Guiyou, a member of the China Daily Hardware Committee, said that the material of the door panel was not the key factor to determine the quality of the anti-theft door, but the thickness of the door panel was the key. According to the relevant standards of anti-theft door manufacturing in China, the thickness of its outer plate shall not be less than 0.8mm.

Qualified anti-theft doors should not only prevent violent demolition, but also prevent technical unlocking. The two complement each other and should not neglect one side. For example, if you simply improve the performance of the anti-theft door against violent demolition, it is easy to make the anti-theft door too thick. The anti-theft door that is too thick is not conducive to use. It is not only hard to open and close, but also has problems such as door panel droop after long-term use.

Zheng Guiyou introduced that the current anti-theft system is developing in a three-dimensional direction, and the mechanical protection is not enough to meet the current anti-theft needs, so the mechanical protection technology of anti-theft doors should be combined with the electronic anti-theft technology.

Is a smart lock safer than a mechanical lock?

China's mechanical locks are divided into A, B and C levels. The anti-theft performance of A level locks is the weakest, while that of C level locks is the strongest. The anti-theft performance of the mechanical lock is determined by the anti sawing, anti shock, anti prying, anti pulling, anti impact and anti technical opening performance of the lock. Li Taijun, member of the expert committee of the China Door and Window Hardware Committee, said that there are no locks that cannot be opened in the world, and anti-theft locks only increase the difficulty of unlocking and prolong the time for malicious unlocking. When selecting the mechanical anti-theft lock, try to select the door lock with high anti-theft level.

In addition to mechanical locks, intelligent door locks are becoming more and more popular, with more and more functions of intelligent door lock systems such as fingerprint recognition, face recognition and remote unlocking. Li Taijun said that compared with mechanical door locks, intelligent door locks are more convenient to use, but their safety performance has not improved.

In the purchase of intelligent door locks, first, select the door lock that is suitable for the door; Second, select high-quality intelligent door locks. The resolution of fingerprint identification door lock should be above 500dpi, and the face recognition door lock should ask whether it is 2D face recognition or 3D face recognition.

During the use of the intelligent door lock, it is necessary to avoid unprofessional disassembly, reduce the contact between the intelligent door lock and water, and pay attention to cleaning. According to Li Taijun, the fingerprint identification door lock may attach dirt after a period of use, affecting the speed and accuracy of fingerprint unlocking.
