Class A lock? Class B lock? What if it don't support heaven and earth hook? Do I choose the touch screen or the button? For the smart password lock, if you have these questions, click this blog to see, which may let you know more.

Let's start with the lock cylinder

Now the products have grasped the user's appearance preference, and come as beautiful as they look. However, locks are different from general consumer goods. They are related to personal safety and property safety. Therefore, the lock cylinder is the key dimension you should consider. As for the appearance, whether it looks good or not has nothing to do with anti-theft.

Although it has various advanced functions, the essence of electronic lock is lock. The lock can be divided into class A lock, class B lock and class C lock according to the lock cylinder level.

Class A lock: the internal structure of class A lock cylinder is very simple, which is limited to the change of marbles, and there are few and shallow marbles slots. The anti technical opening time is within 1 minute, and the mutual opening rate is very high. The marble structure is single row marble or cross lock.

Class B lock: the key of class B lock is a flat key with double rows of marble slots. The difference from class A lock is that there are a row of curved and irregular lines on the key surface. It is safer than class A lock.

Class C lock: the safest lock at present. The key is in the form of single-sided blade inner milling slot, outer milling slot key or double row + blade. The type of lock cylinder is side column lock cylinder. It cannot be opened technically after 270 minutes according to the detection of the Ministry of public security, and the mutual opening rate of the area is zero (1 / 16 million). The marble structure is double row blades and V-shaped side column locking; If the lock cylinder is opened with a strong twisting tool, the interior of the lock cylinder will be damaged, self explosion and locked, resulting in failure to open.

At present, the anti-theft level of qualified electronic lock products is basically the same as that of class C lock or even higher. In addition, electronic locks are more convenient than traditional locks, so more and more users begin to choose electronic locks.

Teach you to choose the right password lock

• Hardware problems

This is a point that many businesses ignore or don't tell you at all. As mentioned earlier, the quality of the lock cylinder determines the safety level of the lock. The biggest hardware of electronic lock is the lock cylinder.

For many electronic locks with poor quality, the common point of the lock cylinder is poor workmanship and poor hardware quality. In particular, the design of lock tongue is also very wonderful - some are just one, some are multiple, but they are very thin. Therefore, we must choose high-quality lock cylinder products. It can be studied from the quality of hardware, the distribution of lock tongue and the quality of lock tongue.

• What about pets at home?

Seeing this problem, some people may be confused. But this is really a headache for many pet owners when purchasing password locks.

Because many pets, especially large and medium-sized dogs, have learned the skills of opening the door. They know that if the handle on the door is planed down, they can open the door and walk out.

Therefore, friends who raise medium and large dogs suggest that you choose the electronic lock with "safety handle" function. You need to press and hold the protrusion on the handle to unlock, otherwise you can't open the door just by pressing the door handle.

• Touch panel or entity keys

For the electronic lock with password input function, the password input area is divided into two structural forms: touch panel and entity key. In order to highlight that their products are better than others, businesses often boast their products without flaws. This leads consumers to hesitate between the two types.

In fact, these two panels have their own advantages:

Touch panel:

It looks like a burst of science and technology. And generally, the electronic locks using the touch panel are equipped with secondary password or virtual password to prevent password leakage. But the disadvantage is the lack of physical feedback, there is a threshold for blind gymnastics, and the elderly may not be able to use it. Now many electronic locks produced by manufacturers are using touch panels.

Entity keys:

The biggest problem with physical keys is that they will leave oil on the keyboard after long-term use, which is easy to be "cracked" by experienced thieves. But the advantage is that it has physical feedback, conforms to the traditional use habits, and is more convenient for the elderly. In addition, its disadvantages can be solved by changing passwords regularly or wearing gloves.

• Heaven and earth hook problem

Heaven and earth hook (called heaven and earth lock in some places) is not a unique product in China, but at least many foreign anti-theft doors do not have the structure of heaven and earth hook.

There is a saying that the heaven and earth hook cannot be unlocked under special circumstances. But the most real reason is that the heaven and earth hook of general civil anti-theft doors basically exists in vain, because the heaven and earth hook is actually directly connected with the lock cylinder. Once the lock cylinder is cracked, the heaven and earth hook will exist in name only.

• Optical identification or semiconductor identification

People with a little research will struggle with which is better, optical identification or semiconductor identification, when buying an electronic lock with fingerprint unlocking. At present, the fingerprint identification of household electronic locks unlocked by fingerprint is mostly optical identification or semiconductor identification.

Similarly, let's talk about the advantages and disadvantages of the two in turn.

Optical identification:

The optical fingerprint sensor has the advantages of mature and reliable technology, low price and wear resistance. The disadvantage is that the recognition rate of fingerprint images with covering on the surface of dirty and dry fingers is very low, and the adaptability to environmental factors such as temperature is poor (it is impossible to recognize when there is water on the hand or too ice on the hand).

Semiconductor identification:

The advantage is that the recognition rate is very high. It can automatically end image acquisition, and the image quality is getting better and better. Strong anti-counterfeiting fingerprint ability. The disadvantage is that it is easily affected by static electricity, so that the sensor can not read the image sometimes, and even destroy the image. The wear resistance is not enough, which affects its service life. Finally, the price is high.
