How to choose a fingerprint lock?

How to choose a fingerprint lock? With the development and innovation of science and technology, many new things come into our lives, such as door locks. The old iron lock has been gradually replaced by the current fingerprint lock, so how to choose the fingerprint lock?

How to choose 1 for fingerprint lock depends on the appearance.

Fingerprint locks made of plastic materials generally have smooth surfaces and bright colors, zinc alloys are slightly rough and sub-colored, and stainless steel is the roughest and sub-colored. Knock: If it is difficult to "see" the fingerprint lock material, we can use "knock" to judge.

Tap gently on the side of the lock body with your fingers. If the sound is unclear or hollow, it is usually plastic. The stainless steel fingerprint lock has a sharp and concentrated sound when striking, with better penetration. However, although zinc alloy is not as sharp as stainless steel, it is much cleaner than plastic products. Weighing: There are still some differences between plastic locks and zinc alloys or stainless steel. Just weigh them.

Firstly, the response speed and accuracy of fingerprint unlocking are tested. The higher the resolution, the more accurate the identification, the faster the response and the better the security. Ask the clerk to input your fingerprint first. When recording fingerprints, observe the difficulty of the clerk entering fingerprints. If a fingerprint can't be recognized after multiple inputs, it can almost be judged that the resolution of the fingerprint lock is not high.

After inputting the fingerprint, randomly test the recognition and response speed of the fingerprint lock to the correct fingerprint. When the command is turned on, its response speed is fast, otherwise it is slow. The faster the reaction speed, the higher the resolution and the better the performance of the lock. Similarly, if we can quickly identify the true and false fingerprints, then its accuracy is good, and vice versa. It's best to try several times when testing. Only by trying several times can we better distinguish its advantages and disadvantages.

Look at the material:

The material of the sleeve is the same as the shell, which is divided into plastic, alloy and stainless steel. Generally, the inside of the ferrule is made of stainless steel, but the ferrule shell is made of alloy or plastic, which is not only weak in violence resistance, but also weak in fire prevention, which is not conducive to safety. Look at the lock points: the lock points of fingerprint lock inserts are mainly divided into single tongue and multiple lock points. The safety of single-tongue lock core is worse than that of multi-lock point, and the anti-pick and anti-explosion performance is also poor.

Look at the function:

At present, the card sets on the market are generally divided into hotel lock card sets, lifting card sets, tongue automatic pop-up card sets and multi-lock self-elastic card sets. Hotel lock core can be pried open with a card, which has poor safety performance;

When using the lifting insert, it is necessary to lift the handle to lock the door when closing the door, which is easy to make people forget to lock it, which is not in line with the consumer's usage habits; The square tongue automatically pops out the ferrule, which solves the shortcoming of lifting the ferrule, but it still can't automatically control the celestial pole; As the fourth generation lock body, the multi-lock self-elastic sleeve is the most superior sleeve so far, with the strongest anti-theft function and the most convenient use.

How to choose 2 1 and the appropriate lock core for fingerprint lock?

Fingerprint lock is smart again, and its function is also anti-theft. Lock anti-theft. Look at the lock core.

At present, the lock core is divided into three levels: A, B and C. The C-level lock is difficult to crack, followed by the B-level lock and the A-level lock. It is recommended to choose a C-class lock core, and the product will be marked with the lock core level when it is purchased through the e-commerce channel.

By the way, here are real ferrules and fake ferrules. The real ferrule means that the lock core runs through the lock body and the keyhole is on the panel. The lock hole of the false ferrule is at the bottom of the fingerprint lock, and the lock core does not penetrate the lock body.

There is a view that the false ferrule has poor anti-theft ability because its lock core does not penetrate the lock body, and if the panel is pried open, it will lose its anti-theft ability. This reason sounds reasonable. In fact, some businesses exaggerate for the sake of publicity.

True and false ferrules are just different in design concept. The fake ferrule hides the keyhole to make the appearance look better and the anti-theft ability is not affected.

Because the fingerprint lock is integrated inside and outside after installation, removing the outer panel can only be violently cracked, but if it is really violently cracked, what is the difference between the true and false card sets?

In the words of the locksmith, the bank vault can be opened as long as the time and method are not limited!

So which ferrule to choose depends on your personal preference for the most exterior design, not hearsay!

2, the choice of fingerprint head.

Fingerprint head is the key to fingerprint unlocking. At present, it is divided into optical fingerprint collection and semiconductor fingerprint collection.

Optical fingerprint lock records fingerprints by light reflection, and then identifies them by algorithm, similar to fingerprint punching machine.

Its disadvantages are slow recognition speed, low fingerprint recognition rate when fingers are dirty and fingerprints are shallow, and inaccurate identification of false fingerprints; Advantages are good durability, long service life and relatively cheap price.

Semiconductor fingerprint lock uses the principles of capacitance, electric field, temperature and pressure to collect fingerprint images, which is the unlocking type before iphone.

Its advantage is to completely eliminate false fingerprints and unlock them even if the fingers are dirty; The disadvantage is that the acquisition sensitivity will be attenuated after a long time of use, and the price is relatively high.

It is recommended to choose semiconductor fingerprint lock, which will have a good experience and you don't have to worry about sensitivity attenuation. Now the manufacturer has optimized the surface material, and the wear resistance has been greatly improved.

3. The choice of push-pull type and push type.

When you check the fingerprint lock products on the e-commerce website, you will find that the appearance of the fingerprint lock is very different. The biggest difference is the handle. This kind of fingerprint lock is called push type, and the fingerprint lock without handle is called push-pull type.

Pressing is our traditional way to open the door. After unlocking, press the handle to open it. Unlocking here refers to the combination of motor-driven clutch and lock tongue. The power to drive the lock tongue comes from the pressing force of the hand and will drive the hook at the same time.

The push-pull type completely relies on the internal motor to drive the lock tongue, and the push-pull force only drives the smallest lock tongue. Because the driving force is not enough to drive the hook, most push-pull types do not support the hook. But thanks to the motor-driven lock tongue, it can be fully automatic, open and close the door and lock it automatically. Note that full automation costs a lot of electricity!

Generally speaking, push-pull and push-pull have their own advantages and disadvantages, and you can choose according to your personal preference.

Yes, the user is worried that it is not safe without the hook, but it doesn't matter, because the hook is connected to the lock core, and it is useless for the lock core to destroy the hook when stealing, and in some cases, the hook is easy to lock, so I was locked by the hook once.

4. Pay attention to practical functions.

① Virtual password.

This function is mainly to prevent voyeurism. For example, the password you set is 123456. If you are worried about password leakage when there are people around, you can press the numbers before and after, as long as there is a continuous 123456 in the middle, you can unlock it.

② Opening mode.

At present, fingerprint locks basically come standard with fingerprint unlocking, card unlocking, Bluetooth unlocking, password unlocking and key unlocking, and some models also have face recognition. Personally, I don't recommend choosing a fingerprint lock with face recognition because it is easy to be cracked.

③ About the prevention of electromagnetic interference.

Fingerprint lock must be designed to prevent it from being cracked by Tesla coil (small black box).

Three seconds before the black box opened the smart lock, it was electromagnetic interference that caused the fingerprint lock to misjudge. Therefore, whether the fingerprint lock has this design is very important.

5. Finally, talk about the material of fingerprint lock.

Fingerprint locks are made of four materials: copper, stainless steel, zinc alloy, aluminum alloy and iron. You don't need to pay too much attention when buying according to your personal budget.

Copper has strong comprehensive properties, but it is the most expensive;

Stainless steel has good stability, but the style and color are single;

Zinc alloy is a common material with high cost performance because of its easy forming and diverse styles.

To sum up:

Fingerprint lock should choose class C lock core;

Fingerprint head selection semiconductor identification;

True ferrule and false ferrule are not important;

Press and push-pull options to see personal preferences;

The more digits in a virtual password, the better. Electromagnetic anti-interference design must have.

How to choose a fingerprint lock? 3 What kind of fingerprint lock is the best?

1, class C lock core is king.

First of all, we should know that the lock core can be unlocked by thieves for dozens of seconds because the anti-theft standard is too low. The national lock cylinder safety standard is divided into three levels: A, B and C, and the C level safety standard is the highest. In the case of technical unlocking, the unlocking time of class C lock core is as long as 270 minutes, which can effectively prevent technical unlocking.

This is a good lock to look after the house.

Can a good lock prevent technical unlocking? The answer is no! In case of theft, a good lock will definitely take the initiative to defend itself. Keleni AI smart lock A8 1 Join AI artificial intelligence technology to help smart locks enter the era of active defense, and thieves can easily deal with it no matter whether it is violent unlocking, technical unlocking or password attempt.

Colleen smart lock is equipped with human biological field detection technology, which can detect the abnormal situation at the door. If someone stays at the door for more than 3 minutes, an early warning will be issued and an alarm message will be sent to the user. In response to the violent unlocking situation, a high-decibel sound warning will be issued, and the alarm will continue and the message will be pushed to the user's mobile phone.

I'm not afraid of stalking.

Thieves stalking users to peek at passwords is also one of the stealing methods. In order to solve this problem, Clooney Smart Lock has designed a virtual password. As long as the middle six digits are correct, it will be locked for 3 minutes after five fingerprint failures or three password failures, and a warning will be issued.

How to choose a fingerprint lock?

Fingerprint lock products on the market can see many unlocking methods. To sum up, these unlocking methods are practical and bring convenience to everyone's life: fingerprint unlocking, password unlocking, mobile phone corresponding app unlocking, and key unlocking.

Judge whether it is a fully automatic lock or a semi-automatic lock.

Fully automatic lock, automatically in the open state after successful identification, push the door to enter, one-step operation, saving effort and worry. It takes two steps to turn the door handle or push and pull the handle after the semi-automatic lock is recognized successfully.

See if the appearance is harmonious and beautiful with the decoration style.

In the choice of smart fingerprint lock, we should pay attention to whether the design is beautiful and durable, and whether it is in harmony with the decoration style.

Is the motor external or internal? Can it drive the hook?

Choosing smart fingerprint lock, the motor part is also very important. Many commercial housing communities have their own doors or self-purchased security doors. For better security, they usually have a hook configuration. Most locks built in motors can't pull the hook because of the small torque, and the hook will be removed during installation, losing the original safety function. The lock of external high-torque motor can drive the hook between heaven and earth.

What is the battery life?

Choosing a smart fingerprint lock is itself looking forward to being safer and more worry-free. At this time, it is necessary to pay attention to whether the fingerprint lock is equipped with a large-capacity or rechargeable battery, and whether there is a low-power reminder function to make everyone comfortable.

Is there an inner handle? Can cat eyes prevent theft?

Some unlocking and locking tools can be inserted through the "cat's eye" of the door, and then the door handle is turned, so it is easy to open the door. The lock without handle in the door can prevent cat's eye theft and is safer.
