What's New

The lock has existed as early as 5000 years ago. We have been used to keep our important things, but before the fingerprint lock appeared, we can't avoid the embarrassing problem of losing the key and being unable to unlock. The appearance of fingerprint lock completely solves the pain point of being rejected due to forgetting the key and losing the key. Many people may have a prejudice against fingerprint lock. This is an electronic product. How can it compare with the traditional door lock? In fact, this idea is wrong. The fingerprint lock has considered this problem at the beginning of design, and even adopted more advanced technical means to ensure the most important quality of security.

Nowadays, there are so many kinds of fingerprint locks on the market that people are overwhelmed. Many fingerprint locks rely on some new functions, new appearance + hype and other marketing gimmicks to obtain the market, but in fact, the most basic security function that should be guaranteed is not done well. Personally, I think it is futile to make great efforts to do some fancy things, and the most important thing is to improve the quality honestly.

To borrow the words of a senior in the industry, making fingerprint lock with Shanzhai spirit is a dead end.

The most important thing of fingerprint lock is product quality, stability and after-sales service. This article will analyze the fingerprint lock brands on the market for you, and learn how to choose a suitable fingerprint lock from simple to deep.

Start literacy. If you want to skip literacy, you can directly pull to the bottom to see the recommendation conclusion.

1. Front and rear panels

The fingerprint lock panel is mainly composed of three materials: zinc alloy material, stainless steel material and aluminum alloy material. The panel made of zinc alloy has good corrosion resistance and high hardness. It is the preferred material for fingerprint lock panel of major manufacturers.

2. Sliding cover

The fingerprint lock with sliding cover can effectively protect the fingerprint identification module of the fingerprint lock and make the service life of the fingerprint identification module longer. However, many fingerprint locks are not designed with sliding cover, because it is more convenient to unlock fingerprint locks without sliding cover. In fact, the fingerprint lock does not have a sliding cover. As long as the fingerprint identification module is well protected, it can be used for a long time. There is no need to choose a fingerprint lock with a sliding cover.

3. Handle

Fingerprint lock can be divided into push-pull type and push-down type according to the shape of the handle. The push-down type has a transverse handle, and the handle needs to be pressed when opening the door, while the push-pull type opens the door by pushing the handle. Fingerprint lock can also be divided into semi-automatic and full-automatic. Semi-automatic generally means that after fingerprint identification, you need to press or push the handle to open the lock tongue, while full-automatic means that after fingerprint identification, the motor will automatically open the lock tongue. At this time, it has been unlocked, and you can enter directly by pushing the door. The semi-automatic door lock can only be locked by lifting the handle. The full-automatic door lock is automatic, so the full-automatic door lock will consume more electricity.

4. Fingerprint head

Fingerprint lock mainly has two mainstream identification modules: optical fingerprint identification module and semiconductor fingerprint identification module. The identification accuracy of semiconductor fingerprint identification module is much higher than that of optical fingerprint identification module, and the rejection rate is low. Now the fingerprint identification modules of mainstream brands adopt the semiconductor method, and the Swedish semiconductor fingerprint identification module is better used in the semiconductor fingerprint identification module.

5. Keyboard

In addition to the fingerprint identification unlocking mode, the fingerprint lock also supports the password input mode. A better fingerprint lock will have the virtual password function. Generally, a good fingerprint lock keyboard will use a panel without fingerprints to prevent others from cracking long-term passwords. For security reasons, it is recommended to change the long-term password of the fingerprint lock at regular intervals.

6. Display screen

The display screen of fingerprint lock is mainly used to display the keyboard and system prompts. The display screen of better fingerprint lock will use the display screen without leaving fingerprints. Once wiped, the fingerprints can be erased, which can effectively prevent password leakage.

7. Camera

In fact, the security of big brand fingerprint locks is high enough. Bosom friends with low budget do not have to choose fingerprint locks with cameras. The fingerprint lock camera function is the icing on the cake. If you want to experience the pleasure of face recognition unlocking, it is recommended that deshmann's R7 and 3D deep face recognition can be recognized accurately at night, and photos can't deceive the system. It's a masterpiece of conscience.

8. Emergency power port

Since the current fingerprint locks are powered by dry battery or lithium battery, it is inevitable that the battery will run out of power and the fingerprint identification system will fail. Therefore, the fingerprint lock will be designed with an emergency power port. When the internal power supply is dead, you can restart the system with the emergency power supply. The emergency power port is generally designed to be hidden and hidden at the bottom of the lock.

9. Key hole

Because the fingerprint identification system can not always ensure that there is no problem, the fingerprint lock will also retain the way of opening the emergency mechanical key when it is designed, and the fingerprint lock will have a key hole. The key hole of fingerprint lock is generally designed to be hidden.

10. Emergency mechanical key

The emergency mechanical key is used to open the fingerprint lock in case of fingerprint identification failure. Each fingerprint lock will be equipped with more than two keys.

11. Emergency knob

The emergency button is used when the motor fails to open the door. The door can also be opened with the emergency knob.

12. Anti lock knob

The design of the anti lock knob is to retain the anti lock function of the traditional lock. Basically, every fingerprint lock will have it. It's safer to lock back after entering the door. Some automatic fingerprint locks will lock back automatically after entering the door, which is very convenient.

13. One key unlocking and locking buttons

The user can unlock and lock the door by pressing one key to unlock and close the lock. It is a very convenient function of fingerprint lock.

14. Battery slot

Generally, the power supply of fingerprint lock includes dry battery and lithium battery, of which lithium battery will be better, because the lithium battery can be recharged after it is dead, which is more convenient.

15. Lock body

The lock body is an important part of the fingerprint lock. When purchasing the lock body, it needs to be selected according to the opening size of the door where the lock body is placed. If the lock body is not selected properly, it may directly affect the service life of the lock. The material of the lock body is mainly stainless steel, but there are also zinc alloy and iron, preferably 304 stainless steel. The lock body is mainly divided into standard lock body and Overlord lock body. The standard lock body is safe enough. If you want to be safer, choose overlord lock body.

16. Circuit board

Small black box can be used to check the quality of fingerprint lock

The internal circuit design of fingerprint lock is also very particular. Generally, the internal circuit of big brand fingerprint lock will have overload protection design, which can effectively prevent the attack of small black box. The strong electromagnetic field inside the lock box can unlock the lock instantly, which can cause the poor quality of the system. Therefore, we must choose a fingerprint lock that can resist the electromagnetic interference of a small black box.

17. Lock cylinder

The lock cylinder is divided into class A, class B and class C. the safety and prying difficulty increase in turn. At present, many brands of fingerprint locks use C-class lock cylinders, such as Samsung, deshman, Cadiz, Philips, Keyu, Xiaomi, etc. generally, the safety factor of these brands of fingerprint locks is very high.

19. Chip

The chip in the fingerprint lock is similar to the CPU of the mobile phone or computer. A good fingerprint identification module needs to be matched with a good fingerprint identification processor to give full play to its advantages. The internal chips of the fingerprint lock of big brand manufacturers adopt self-developed or foreign special processing chips, with strong performance and high security.

20. Motor

The motor is the device that drives the lock tongue and the heaven and earth hook. Now the fingerprint lock of big brands is safe enough. It is not recommended to install the heaven and earth hook, because the heaven and earth hook will increase the burden of the motor, reduce the service life of the motor and the service time of the battery.
