What is the security and anti-theft capability? The confusion and confusion of buying electronic smart door locks

The electronic Smart Door Lock, known as the new "home guardian", has developed rapidly in recent years, but many consumers do not know much about it, and even have some doubts about its safety, so they dare not buy it easily. In the field of production, electronic smart door locks also have problems such as inconsistent standards, imperfect after-sales service, and uneven quality. So, what thresholds does the industry need to pass in order to develop healthily? What is the security and anti-theft ability of electronic smart door locks? How should consumers choose smart door lock products? This reporter conducted an investigation.

Do you want to install the sky and earth hook?

"The electronic smart door lock does not have the heaven and earth hook that can be extended into the door frame of the traditional anti-theft door, and only has one deadbolt. Will the security be reduced?" Beijing consumer Wu Xiao raised her doubts to the reporter. The most fundamental demand of consumers for door locks is safety. The reporter found that among consumers' various doubts about electronic smart door locks, whether the safety hooks disappear is the most concerned issue.

According to the reporter's understanding, the relevant regulations of Tiandi hook have not been included in the national standard for locks, but in the national standard for doors. In fact, compared with traditional mechanical locks, electronic smart door locks are not only more convenient and smart, but their safety has not deteriorated.

The reporter investigated and learned that the smart door lock products sold on the market themselves are divided into two types: with hooks and without hooks, whether they need to be installed or not can not be generalized. It is understood that for the door itself, the main lock body drives the upper and lower secondary locks through the heaven and earth hook, thereby increasing the number of latch bolts on the door. The number of lock points is increased, one can play the role of fixing the door frame, preventing deformation and enhancing airtightness. Second, the safety performance of anti-prying and anti-violence opening has been improved.

Lv Jiying, vice chairman and senior engineer of China Hardware Products Association, introduced to the reporter of "China Consumer News": "Combining the actual role of the heaven and earth hook, first of all, from the dimension of preventing the deformation of the door body, if the original door body has been deformed Or the switch lock is blocked, the transmission resistance of the heaven and earth hook will increase the risk of failure of the Smart Lock. It is not recommended to install the heaven and earth hook for this type of door, especially for the fully automatic lock driven by the motor. It is not recommended to install the heaven and earth hook; From the perspective of security, consumers feel that more locks are more secure and firm. However, from the data disclosed by the public security department in Changsha area, about 80% of the thieves use magnetic cards to unlock the door. 15% use technology to unlock, about 5% break windows, and only about 1% use violence to destroy doors and locks to enter the house. It can be seen that the rate of violent destruction and door breaking is very low, and most of them are technical unlocking. After all, only the main lock is required. After being opened by technology, more lock points will be opened together. Based on this, it is not necessary to install the heaven and earth hook. Moreover, the traditional door lock with the heaven and earth hook actually has disadvantages. For example, in the event of fire and other emergencies, it requires violence to open the door When saving people, it is necessary to cut the upper and lower locking points, which delays the rescue time."
