What are Fingerprint Door Locks

 Fingerprint door locks is a kind of intelligent locks with human fingerprints as the recognition carrier and means, which is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint locks are generally composed of two parts: electronic identification and control, and mechanical linkage system. The uniqueness and non-replicability of live fingerprints determine that fingerprint locks are the most secure locks among all locks. Fingerprint door locks should be equipped with emergency mechanical keys in addition to fingerprint recognition.- Fingerprint door locks manufacturer

Due to the popularity of smart home, fingerprint door locks have now entered thousands of households. The function of fingerprint door locks is also more and more comprehensive, from the previous fingerprint, password lock upgraded to the current NFC induction lock, cell phone network lock.

Fingerprints are the uneven lines on the skin of the front side of the end of the finger, although the fingerprint is only a small part of the human skin, but it contains a lot of information, these lines in the pattern, breakpoints and intersections are different, and in the information processing, they are called “features”, which have been proved medically to be different for each finger, and these features have uniqueness and permanence, so we can correspond a person with his fingerprints, by comparing his fingerprint features with the pre-stored fingerprint features, we can verify his real identity. Therefore, we can correspond a person with his fingerprints and verify his real identity by comparing his fingerprint features with the pre-saved fingerprint features.

Function – Fingerprint door lock manufacturers

Fingerprint open, password open, emergency key open, and now also added with the card open way, so that consumers more trust and choose fingerprint locks. There are many manufacturers in their products integrated doorbell, voice prompts, networking, telephone alarm and other one or two dozen functions. Users at first glance quite a lot of features, so it seems to save other unnecessary costs, may be moved. Personally believe that this is an irresponsible design manufacturers, fingerprint locks, the main function is security and convenience. Fingerprint locks in addition to open the door, generally have to add, delete and empty fingerprints, high-performance fingerprint locks are also equipped with LCD touch screen and other man-machine dialogue system, the level of intelligence is high, the operation is also relatively convenient and can provide operational guidance, query the use of records and built-in parameters, set up the status and other functions. Fingerprint management functions: add fingerprints, delete fingerprints, clear fingerprints, set the system parameters and other functions, while ordinary users only open the door.

In general, fingerprint door locks can be equipped with passwords, cards and other ways to open.

The core components of fingerprint door locks: motherboard, clutch (semi-automatic lock), fingerprint collector, cryptography, microprocessor (CPU), intelligent emergency key, power supply equipment (battery charger transformer, etc.).

Power supply – Fingerprint door locks manufacturer

Fingerprint door locks are generally powered by 4 or 8 alkaline batteries, which can be used for about one year (depending on the function, power consumption design, number of times of use, etc.). According to the industry standard production of anti-theft fingerprint locks, it should be equipped with emergency power supply interface, which can be powered by 9V stacked battery. These two kinds of batteries are available in supermarkets.

Intelligent Convenience – Fingerprint door locks manufacturer

According to the division of the degree of intelligence, the current fingerprint door locks are divided into two categories: fully automatic fingerprint door locks and semi-automatic fingerprint locks. Full-automatic fingerprint lock technical requirements are higher, more intelligent, with a special lock body, easier to use and more convenient, humanized, designed for the family, linkage smart home intelligent equipment, to achieve three-dimensional anti-theft, semi-automatic fingerprint locks are more common in the market at present, the technical requirements are not high, most of them are mechanical locks evolved, some equipped with a clutch lock body Some even do not have a lock body, hanging directly on the mechanical lock body Use Some of them are equipped with clutch locks, and some even have no lock body and are directly mounted on the mechanical lock body.

Fingerprint anti-theft – Fingerprint door locks manufacturer

Many people think that semi-automatic fingerprint door locks Hanging heaven and earth locks, locks, security, in fact, there is a misunderstanding here, because the security of the door locks have a few important parts of the embodiment: 1 fingerprint identification and security level 2 equipped with the level of the key 3 using the material 4 lock structure 5 product structure itself.

We found in real life and cases, the first choice to open the door lock is the keyhole, if equipped with super B-class basic difficult to open, and the second is through the cat’s eye Door and other channels to open, which relates to the structure of the product itself, and directly smash the lock Cutting the door lock panel is very little, this has to do with the structure of the lock body and the panel material,, but no matter what kind of hook with the heaven and earth have no relationship to the semi-automatic fingerprint locks and vice locks are all by the handle of the heaven and earth hooks and vice locks are all by the handle of the door. and vice locks are driven by the handle up or down pressure, itself depends on the force, any kind of way as long as the release of the clutch bolt heaven and earth hook is a setup, just visual security, heart feel strong, in fact, it is a paper tiger, which is why the international big brands have adopted the important reason for the full-automatic!

According to: Recognition carrier – Fingerprint door locks manufacturer

According to the recognition carrier division, fingerprint lock can be divided into optical fingerprint lock and semiconductor (capacitive, pressure lever and thermal induction) fingerprint door locks two kinds.

Semiconductor fingerprint collector is through the human fingerprint concave and convex principle of the collector on the current to have an impact, so as to realize its uniqueness, semiconductor fingerprint collector is relatively stable, fast response speed, refusal of truth and other characteristics and is widely used in customs, troops, banks and other highly confidential places.

Optical fingerprint collector is the original user’s fingerprint on the collector, and then photographed the user’s fingerprints (equivalent to help fingerprints to take a picture), through the record of the initial fingerprint image to compare the user’s fingerprints; so the optical fingerprint collector on the resolution requirements of the higher, the general resolution of the product should reach 500 dpi to be considered as a qualified product.

Folding Description – Fingerprint door locks manufacturer

Fingerprint locks utilize the above principles to produce security products through the precise combination of electronic and mechanical components. The essence of fingerprint door locks is safety, convenience and fashion:

Rejection Rate and Recognition Rate

The rejection rate and recognition rate is undoubtedly one of the most important indicators, which can also be called rejection rate and false recognition rate, and there are several ways to express them:

(1) The resolution of the fingerprint head used, e.g. 500DPI.

The precision of existing optical fingerprint sensors is generally 300,000 pixels, and there are also individual companies using 100,000 pixels.

(2) The way of percentage: such as some of the parameters written on the way.

Of course, this is the parameter promoted by each enterprise, whether it is 500 DPI or the rejection rate <0.1% for ordinary users is just a concept, the test standard is “rejection rate should be ≤3% to recognize the false rate ≤0.001%”.

(3) for the “rejection rate, false rate” between each other, to a certain extent, is correct, this seems to be in the mathematical “hypothesis testing” concept: at the same level, the rejection rate is high, the false rate is low, and vice versa. It’s an inverse relationship. But why is said to a certain extent is correct, because if the process and technology to improve the level of these two indicators can be reduced, so the essence or to improve the technical level. Some manufacturers in order to speed up the certification, through the practice of reducing the level of security, at the expense of security, to create the illusion of speed, recognition ability. This appears more in the sample lock or demo lock.

According to the relevant standards, the security level of fingerprint security locks for home entry doors should be 3 levels, i.e., the rejection rate of ≤ 0.1%, the recognition rate of ≤ 0.001%.

Durability – Fingerprint door locks manufacturer

Theoretically speaking, one more function is one more program, then the possibility of product damage is a little bit greater. But this is a comparison between manufacturers of the same technical strength, if the technical strength of the high, then their products can be done than those with poor technical strength of the product features more, good quality.

The more critical point is: the benefits of more features and features bring the risk of comparison. If the function brings big benefit, then it can be said that this increase is worthwhile, just like you drive the speed limit of 100 yards, you then step on the gas need to pay the price of violations or car accidents is the same reason. If the feature doesn’t give you any benefit, then the feature is redundant. So the key is not to consider what “one more feature is one more risk” but whether the risk is worth taking.

Like the networking function, on the one hand, fingerprints in the network transmission process of the stability of the industry is not sure, on the other hand, to destroy the existing renovation, and more importantly, once invaded by a virus, there will be no “medicine”. Once access to the network, the possibility of being attacked will greatly increase. The telephone alarm a class of superimposed security technology, it is necessary to set up a separate related equipment, and there are indoor radiation and false alarm problems. Especially the latter, in addition to the fingerprint lock itself, due to external factors such as technology and environment, once the second false alarm, the user will choose to dismantle the lock.

About the LCD screen – Fingerprint door locks manufacturer

At present, there are not many manufacturers who can provide this kind of configuration in domestic products, and most of them still only rely on the light and sound prompts that come with the fingerprint module to realize. Setting up the LCD display can make the user’s operation more convenient and simple. Power consumption is slightly higher than with lights and sounds. Whether you need it or not depends on the consumption of your own needs. But the use of LCD can certainly make the fingerprint lock smarter and simpler for the user to operate, which is obvious. Just like a cell phone, the display is black, you can still make a phone call, it’s just not convenient. Configuration of liquid crystal is not a simple accumulation of materials, but also involves the rational design of software and circuit system. In short, the use of this technology, just like the fingerprint door locks itself to replace the mechanical lock, is the inevitable development of technology and the market!

Currently no longer meet the previous LCD display, many manufacturers have adopted the latest OLED high-definition screen, which is a high-end product must be beautiful, convenient operation, convenient and practical is an important part!

About Sensor – Fingerprint door locks manufacturer

At present, fingerprint sensors are mainly optical sensors and semiconductor sensors, optical sensors mainly refers to the use of coms and other light sensor devices, access to fingerprint images, the market are generally made into a whole module form, such sensors are less expensive, but the volume is larger, generally used in fingerprint door locks, fingerprint access control and other products.

Semiconductor sensors are mainly monopolized by Swedish FingerPrint Cards, AuthenTec and other fingerprint sensor manufacturers, divided into hanging type (such as AES1711) and face (such as FPC1011, TSC2) two kinds of face price is relatively high, but the performance is better, and most of them are used in customs, the military, banks and other important areas. Nowadays, with the improvement of people’s awareness of home security, more and more manufacturers will be semiconductor faceted sensors used in civilian areas, the user experience is better. Hanging rubbing smaller size, lower price, but the experience is worse, scratching the direction of the speed and so on have an impact on the effect.

Fingerprint module – Fingerprint door locks manufacturer

As the front end of the industry chain, there are professional software companies and fingerprint lock R & D enterprises to provide fingerprint modules. Most of these modules are imported from abroad and then improved and provided with corresponding secondary development space. Only after the secondary development of the fingerprint module can really play its role. The technical strength of domestic manufacturers is reflected here. Just like a computer, Windows XP are installed for you, but you want to be practical, you have to install some specialized software, such as OFFICE office system, Winrar decompression tools. Manufacturers have the technical force, will be the second deep development, so that the module to achieve the product design function required. No technical force, brought to use, these products out, on the appearance of different, other similar, not much difference, product technology upgrades and after-sales is no way to talk about.

Core technology – Fingerprint door locks manufacturer

As a fingerprint door locks, the most important thing should be the algorithm chip, that is, the heart to be good, you mechanical part of the good again, if the recognition of false higher, just anyone’s fingerprints can open, then what is the use of it?

Secondly, no matter what the lock, its essence is still a mechanical product. fingerprint door locks belong to the use of modern high-tech transformation of traditional industries, its core technology is the first mechanical technology to grasp. Mechanical technology mainly consists of the following three aspects:

1, the rational design of the front and rear panels, i.e., the appearance, is significantly different from the signs of similar products, and more importantly, the internal structure of the layout, which directly determines the stability of the product and the function to play. This process, involving design, mold making, surface treatment and many other aspects. Therefore, the more styles of manufacturers, relatively speaking, the development and design capabilities, better stability.

2, lock body. That can be associated with the door lock tongue of the mother. Lock body is good or bad, directly determines the life of the product. This is mechanical technology, the most core technology, but also the lifeblood of the fingerprint lock, but also the industry, the most difficult to solve the problem. 95% of the existing production units can not solve the problem, mainly through the outsourcing of the way supporting. Strength of manufacturers, embracing their own design, development of the lock body capacity. Therefore, the lock body is the real embodiment of the core components of the manufacturer’s technical level, but also the core technology of the entire fingerprint lock.

3, motor. The motor is the driver. Just like the driver software of the computer. It is a connection device between electronic and mechanical, the power of the conversion center, plays a major role in the beginning and end. If the motor stops working or obstacles, the lock will automatically open and can not be locked.

4, fingerprint module and application system. This is the basis of the electronic part. Fingerprint module, the current peer function is similar, mainly depends on the use of which chip, the use of which algorithm, such as Hangzhou Sheng Yuan algorithm chip, after a long period of market verification, the effect is very good.

5, circuit design. Clear circuit design and wiring is also an important factor in ensuring product stability.

Selection criteria – Fingerprint door locks manufacturer

Criterion 1: There is no ANSI certification

Fingerprint door locks were really introduced to China from the United States in 2005. At that time, the U.S. high-end fingerprint lock brand Dijil and the world’s top 500 companies Ingersoll Rand dominated the high-end fingerprint lock market. Therefore, the general quality of reliable fingerprint locks must pass the highest quality level in the United States – ANSI certification.

ANSI certification, as the highest level of the strictest international quality certification, is a guarantee and symbol of the high quality of the product. The certification through the operation of the product, life, strength, safety, surface and materials to carry out rigorous testing, the requirements of uniform standards, unified technology, unified interpretation, to achieve a consistent understanding of the standards and technical requirements in order to improve the core competitiveness of the product to give the buyer the greatest confidence.

Standard 2: Is there a full-proof design

Fingerprint door locks as door locks security high-tech products, not only can protect the family property, but also can let the family use the peace of mind. Especially in today’s society, some of the root causes of conflicts still exist, fingerprint locks have a full-proof design is very important.

High security performance of fingerprint locks, will be a perfect blend of traditional mechanical technology and modern high-tech fingerprint recognition technology, with anti-theft, riot, water, fire, moisture, corrosion, temperature, shock, abrasion, rain, sun and other 360 ° full-proof patented design, and the structure of the use of pure stainless steel materials, to achieve the highest level of security precautions.

Standard 3: whether there is a locking function that closes the door

In our daily life, close the door are often forget to lock, especially vulnerable groups (such as the elderly or children) will forget to lock the door, which will leave the hidden danger of burglary with the tail into the home. When choosing fingerprint locks, to understand whether the fingerprint locks have the function of closing the door that locks, in order to eliminate this security risk, the use of more assured.

Standard 4: there is no perfect after-sales service

According to industry professionals, the current fingerprint door locks manufacturers sales and service point network is generally not large, or even no after-sales service point, after-sales service commitment to form a false. When you buy a fingerprint lock, be sure to understand the fingerprint door locks brand has no national after-sales service points, there is no user-friendly opening of the national unified toll-free after-sales service hotline, and commitment to 24 hours to provide solutions to the problem.

Criterion 5: Whether there is a U-shaped free handle

In the market, many fingerprint door locks do not have the function of U-shaped free handle.

Because, fingerprint lock products with U-shaped free handle function, can take care of the vulnerable groups (such as the elderly and children) when using the accidental injury, showing the fingerprint lock brand in the design of ingenuity. Moreover, the U-shaped free handle can resist violence and prevent the phenomenon of misuse. Therefore, make sure to check whether the fingerprint lock is equipped with a U-shaped free handle.

Criterion 6: Which company’s brand products

The real fingerprint door locks, usually after 5 years of time precipitation, otherwise the quality of the product will not be guaranteed. And, a quality fingerprint lock products, after the door lock clinical testing, fingerprint identification technology, user feedback, product development, product design, mold manufacturing, die-casting, stamping, drilling, lathe, wire cutting, electronic applications, polishing and plating, assembly, quality inspection and other 110 processes.

Criterion 7: There is no authoritative program recognition

Fingerprint locks are generally used for high confidentiality and security protection level of high places, civilization is only developed in recent years. Reliable fingerprint lock brands are generally used in some national authority.

Criterion 8: there is no multi-point latch protection

Nowadays, social problems are complex, the security performance of door locks is more important. Fingerprint locks generally use stainless steel material lock tongue, however, most fingerprint door locks are single lock tongue, not suitable for national use.

Criterion 9: whether to use biological fingerprint identification technology

Fingerprint locks have become a new generation of door locks on behalf of the key is the use of biological fingerprint identification technology, the use of human fingerprint uniqueness and non-replicability. The American biometric fingerprint identification technology is widely recommended here.

Because of more than 5 billion people in the world, each person’s fingerprint is unique, which is the same as the world does not have a piece of the same leaf. There is also the U.S. biological fingerprint identification technology in the use of fingerprint identification, the temperature of the human body, temperature, and even the speed of blood flow and so on have certain requirements, to prevent the copying of lawbreakers and the use of fingerprints of the hidden danger, a good solution to the problem of other people imitation key to open the door to protect the use of security, so that the fingerprint locks have an unparalleled high security performance.

Choosing – Fingerprint door locks manufacturer

Choosing the features of a lock is partly about meeting your needs, but it’s also about choosing the quality of the lock. A good company will often have no less than five or more fingerprint locks ranging from high school to low school for users to choose from. Users will generally choose from the use of their own products: there are used for entry doors, divided into metal doors and wooden doors, there are users of interior doors, common to wooden doors, but also for villa gates wood, and so on. Usually use the basic functions are:

(1) can be for more than one person fingerprints open the door (a home or office is often more than just one or two people), product quality should be stable, good performance;

(2) can be divided into permissions to open the door (it is not possible to let the head of household and nanny, cleaner has the same open door management rights);

(3) can be free to add or subtract the fingerprints to open the door (nanny left can be convenient to remove her fingerprints);

(4) It is best to have the inquiry record function (you can always view the door-opening record, sometimes it can be a key evidence, generally need to bring a display screen);

(5) appropriate with a little password function (fingerprint part is, after all, the electronic part of the time there may be bad, temporary situation, the head of household can open the door with a password), in the choice of trying not to choose too much emphasis on the password function of the product, after all, the password is not as safe as the fingerprint. Usually there are 4 keys and 12 keys. As far as possible in daily life, do not use the password to open the door, you can effectively avoid being stolen;

(6) must come with a mechanical key, which is a kind of back-up way to open the door, like airplanes and automobiles, although there is an automatic control state, but still retains the manual control part, which is a kind of security considerations:

Any electronic part of the possibility of error, relatively speaking, the mechanical part of the much more stable, retain the mechanical key of the lock as the home of the backup open the door, you can lock the electronic part of the problem in time to open the door and convenient maintenance. Imagine if there is a fire in the house, or the thief damaged the electronic part of your door due to failure to pick the lock what do you do? Don’t be tempted by the psychological so-called security, and put the back way, choose the kind of door locks without mechanical key. In fact, the use of fingerprint locks, the most important thing is not to improve security, but to enjoy the convenience of fingerprint locks, need to strengthen the security of fingerprint locks, you can let the fingerprint locks connected to the smart home system. At present, some fingerprint lock manufacturers reserve development ports for fingerprint locks. In smart home, only simple development of fingerprint locks is needed to monitor the status of fingerprint locks in real time, so as to improve the security of fingerprint locks.

(7) Choose a good lock cylinder. The good or bad of the mechanical key lock cylinder is directly related to the anti-picking and stability of your door. This part is also very important – Fingerprint door locks manufacturer

No longer good, ultimately inseparable from the lock cylinder part. In general the strength of the fingerprint lock manufacturer will choose high-grade lock core, so that the quality of the product can certainly be guaranteed. The most obvious especially consumers can look at the key number of bullets and the number of shades of gear. Try to choose the number of bullets and the number of shades of gears more products. Shallow and deep file number of the number of bullets times, is the key amount of this mechanical key, the larger the key amount, the better the security. National standards generally require at least A locks, good fingerprint lock manufacturers generally configure super B mechanical key.

(8)other fancy features is best not to. Basically not practical, more than one function more than one kind of bad possibility, the product is bad after you repair is not repair, repair, maintenance personnel will charge you maintenance fees (door-to-door is not free).
