1. Properties

The first thing we know is the products like smart lock. It is one of the series of smart home products. It is the first guard gate of home and a very important product of smart home products.

When the smart lock first appeared in the public view, the most basic functions include fingerprint unlocking, password unlocking, card swiping unlocking and so on. Nowadays, with the vigorous development of intelligent technology, functions such as one click door opening, temporary password generation, mobile app and applet control have been added, which are more and more convenient and fast!

2. Unlocking mode


In the past, the conventional unlocking methods of fingerprint lock were only fingerprint identification and password identification. In addition to these two methods, smart lock also extended to mobile app remote control unlocking, magnetic card unlocking and other methods.


The known traditional fingerprint lock only supports a single unlocking mode, while the intelligent lock is different. It can not only realize the combined unlocking mode through independent setting, but also has a variety of unlocking forms, which can be used by every member of the family according to their preferences.

3. Security and privacy


In terms of the security performance of the smart lock, it not only has the safe and practical functions such as anti prying alarm, anti coercion alarm and virtual password, but also has the function of real-time information push, so that the administrator can clearly understand the trial state of the lock at any time and in time.


In terms of information security, fingerprint, password, magnetic card and other information, as well as the user's usual door opening and closing information data, will be stored in the chip built in the smart lock, and these information cannot be obtained from the outside.


4. Lock cylinder


Now the most direct, obvious and important thing to test whether the intelligent lock has high security is to look at its lock cylinder. At present, the standard lock cylinder given by the Ministry of public security has three levels, namely class a lock cylinder, class B lock cylinder and class C lock cylinder.


Class a lock cylinder:


Class a anti-theft lock key is now mainly a word key and a cross key. Its internal structure is particularly simple, which is limited to the changes between marbles. There are few and shallow marbles slots. In terms of anti-theft performance, the unlocking time is about three minutes. If you are more skilled, it will be faster.

Class B lock cylinder:


Different from class a lock cylinder, the flat key is used, and there are double rows of bullet slots. There is a row of curved and irregular lines on the key, which belongs to a safer level.




There are three main types of class B lock cylinder. If you are skilled in unlocking, it only takes 5-20 minutes. If you want to use a strong twist tool to unlock, it only takes 1 minute to unlock.

Class C lock cylinder:


At present, the level of lock cylinder is the safest. The key is generally a double-sided double row belt with internal milling groove, and there is a blade or curve next to it. For teachers who are skilled in this kind of lock cylinder, it takes at least 270 minutes to unlock it. If you want to use a strong twist tool to unlock the lock, the interior of the lock cylinder will be damaged, self exploding and locked, and it will be unable to open.

5. Panel


This can be seen from the previous mechanical lock. When it is used for a long time, its appearance will fade, mildew and rust. The reason for these conditions is that the panel material of mechanical lock is relatively poor, and the materials of iron sheet and aluminum alloy are used more, which are easy to be corroded and not resistant to high temperature.

Lock is a security product and the first guard gate of the home. It should not only have a high level of security, but also be able to resist fire and high temperature. Therefore, special attention should be paid to the selection of lock materials. It is suggested that before starting with intelligent lock products, we should focus on asking the salesperson or online customer service what the lock material is made of.
