First of all, online shopping is not recommended. Online shopping is not recommended. Online shopping is not recommended. Important things are said three times! This kind of door lock is not the end of the installation, because the installation of the fingerprint lock is very important, many online stores are directly installed on the Internet locksmith, it is directly to find a way, the fastest to install it on you Originally, you could open a small hole. You have to cut a big hole with an angle grinder to save trouble. Anyway, the fingerprint lock is large and can be covered. However, it is not the case.
Choose a local fingerprint lock. Under normal circumstances, in order to do word-of-mouth, you will be relatively responsible, but if you are looking for a store that cooperates with the locksmith, you don't have a team, it is not ideal. However, the local agent is, in general, the installation requirements will be stricter. After all, installing the fingerprint lock is simple and simple, but the key is some details. If it is not handled well, it will bring some inconvenience to the use. The hidden danger of failure. Online can learn about the price, such as the low price of the double eleven, but it is recommended not to look at what the so-called top ten brands, people who know know, are spending money to buy, and even some of the top ten brands, It is a fake web page that costs money.
First talk about the choice of fingerprint head, the fingerprint head is now divided into two main types, one is optics, the other is semiconductor, we first talk about the principle of optics, optics, similar to taking a photo of the fingerprint, and then according to the fingerprint in the database for comparison, The advantages of optics are durability, obvious disadvantages, poor recognition rate, many old people, children, light fingerprints, fingerprint failures, let you want to die, can not wait, and finally only use passwords and cards. The other one, although not so serious, is also a potential risk. Nowadays, in addition to a few of the locks used in China, it is its own solution or a really good company algorithm. The others are all used in a pile. A small company made a full set of fingerprint lock solutions, even the company that sells a lot of locks on Tmall Jingdong, the kind of lock, directly use the fake fingerprint film bought on Taobao, easy to open, although not to It was easy to get their fingerprints, but who knows that there will be no fingerprint film tools on the Taobao that can be used from the cup.
As for the so-called optical bio-recognition, it is not a creature to change your personal fingerprints to identify them. It is estimated that all the dogs can be attached to the fingerprint film, so it is recommended that the optical fingerprint heads be passed (especially in the north). Generally speaking, in this case, most of the fingerprint locks below 1,000 yuan are directly passed, but it is not excluded that some individual brands, even unlicensed assembly factory stores, fight the price and do very low. In fact, some factories, can it be called a factory? In fact, it is a workshop. If you have seen the news of Shenzhen as a cottage machine, you can imagine what it is like to do fingerprint locks now.
We will go back to the semiconductor fingerprint head. Relatively speaking, the semiconductor will be safer and the recognition efficiency will be better. However, some fingerprints will not be recognized, but it is relatively good. Other semiconductor identifiers also have RF penetration. Some have self-learning functions, these are more expensive, although the cost is limited, but the price of the lock is higher. The fingerprint head of a semiconductor has an unavoidable problem. Compared with optics, it is very fragile and does not have wear resistance. It will gradually appear after one year, because of wear and tear, reducing recognition efficiency, and slowing down the reaction rate. How long you have to live depends on your level of care. This is true of many small brands and even low-end locks of some big brands. For some good locks, a layer of protection will be made on the semiconductor, so that the wear resistance will be relatively good, normal use, it is estimated that there will be no problems within 3-5 years, as for life, it is the same Look at your love.
Recently, a lock called X guest on a certain meter, the semiconductor recognizer is placed on the handle, and what concentric circles are blown. It seems that, in many respects, the handle is gripped and the thumb is directly recognized and unlocked, but in In real life, many homes will touch the wall when they open the door. So do you really think about the protection and life of the fingerprint head? I think this lock is only good value, practical. Sex is not enough, it is estimated that it is also a certain entrepreneurial team of a certain Internet company to do a single job, to be a design, to pull an investment, to start a company, there is no own factory, there is not much order, so find the foundry, The level of spare parts suppliers, process technology, and precision have not been known.
For the fingerprint door lock, my opinion is that it must be foolproof, so the choice of fingerprint lock, I think, if you choose to use the fingerprint lock, then choose a good quality fingerprint lock, and also have a good brand after sale, which requires The purchase must have a local agent. Some things can be purchased online, but some things, the risk of online shopping, you have to bear. After all, the lock of online shopping, the money into the pockets of people, can not care about you too much to review, after all, as long as the installation can be used, and then the lock, there will not be too many problems in a short time, as long as you can use, look at luck.
Now the fingerprint lock password has a dummy password, anti-peep function, so there is nothing to say, but a little, don't buy mechanical buttons, what is the reason, or wear, use more, those keys, wear is serious, it is very It's easy to guess the password. This point, online selling is relatively hot, Deschman is the most favorite to use mechanical buttons, saving costs. As for his other problems, because there is no real thing, just relying on the picture to guess, so can not confirm, do not say. Cards are actually not particularly safe and have the characteristics of easy copying. However, in order to facilitate the elderly, almost all brands have done it. However, it seems that the 360 ​​locks of the recent crowdfunding did not do this function. The problem of the 360 ​​lock, I will talk about it later.
Mechanical key, this is a mandatory requirement of the state. The fingerprint lock must have a key. Manshen has made a smart lock cylinder and directly replaces the lock cylinder. This completely eliminates the key. Others don’t say, is this a bit? Does it not comply with national regulations? If the stability is not up, if there is a problem, then only the violent unlocking, buy this smart lock cylinder, that is, everything depends on the quality of Manshen, there is no alternative.
Let's talk about other ways of unlocking. There are two gimmicks. One is remotely open and the other is Bluetooth. These two points are easy for hackers. You can find a lot of videos directly on the Internet, so you can purchase fingerprint locks. Don't buy anything remote unlocking, Bluetooth unlocking, just gimmick, there is no practicality, really let the person you allow to enter the house, tell him how the password? Going back and changing it is, let's say that each lock can set a lot of group passwords, you can set a password to be told to others, and use it to change. There are also some miscellaneous cards, what kind of app dynamic password, a download software, followed by a wave of software, dare to use it! Therefore, regarding the network involved, it is recommended to select a fingerprint lock with only one-way data transmission protocol function such as door opening reminder and remote alarm.
There are three types of fingerprint locks. The first one is the most. The first one is the horizontal handle. It is similar to the ordinary lock. Only if the verification is successful, the handle can be opened. Some will choose the self-locking lock and imitate Wang Limen. However, why the industry sells fingerprint locks, there are few standard self-elastic locks, because of stability, although it may be much better now, but the stability is not as good as the traditional double fast double live lock. In addition, in the fingerprint lock market, the lock body is also a place with a routine. The same type of lock body, the material work is different, can be a few dozen. The automatic universal interchangeable lock to be mentioned later, without changing the lock body, is easy to install. Continue to use the lock body that your home buys, and even buy the lock body of the door that has been used in the house. It has been used for so many years, change the lock. And continue to use, the worst kind of goods, cheap even less than 10 yuan. I don’t even say it.
The second type, the round handle, this kind of feeling similar to the rotating key, is equivalent to your key handle becomes huge, but usually the handle can not open the door, only the verification can open the door, such a lock, in fact, is not recommended, The lock factory claims to be a universal interchange, so you don't have to change your original lock body, saving a cost, but if you have been a lock for many years, this is not a good lock, then change your fingerprint lock. Also have to use your previous lock body. And such a fingerprint lock, open the door a few turns, lock the door or turn a few laps, no trouble, in addition to not having the key, it is not much easier. Many small factories, because there are not many lock body guide pieces to adapt to a variety of door lock models, so the so-called universal interchange locks are OEM, to solve their need to adapt to various door locks.
The third type is actually an extension of the first type, which is to change the manual rotation to automatic rotation, that is, to drive the interlocking of the middle cylinder by the motor drive. The fourth type, the built-in lock body of the clutch, there is no heaven and earth hook function, and Samsung's electronic lock body, in fact, I think the difference is not big, now the hottest, is the endorsement of Liu Tao's K7 and k8, all said The safety of the heaven and earth hooks is not very useful, so for some doors with heaven and earth hooks, when installing, either remove them or tie them with iron wire so that they no longer work, not to say whether it is true or not. Does it matter? But the door itself has the function, you canceled him, it always makes people feel uncomfortable. Although it may not really help, but what do consumers think about it, when they buy a lock, they don’t explain it. When they lock it, they only say that they can only recognize their noses. In recent years, Kai Di Shi, the real impact of advertising, Liu Tao endorsement, all platforms to vigorously advertise, investment is not small, but the price is only wool out of the sheep. In addition, when buying, there is one point to note, do not choose, lithium battery, because the automatic lock, many because of the current needs, choose the lithium battery, but the lithium battery has the problem of self-discharge, just like the shou machine battery, You are fully charged, put it for a while, even if you don't use it, the battery will naturally run out, and the battery life will be constant. It will be shorter than one time, and finally you have to pay for a new battery. There are also some automatic locks, even the design of the mechanical keyhole, the result, like the smart lock cylinder of Manshen, the quality and stability of the fight is over.
Let me talk about the material problem. Let me talk about the lock body. The material is good. It is generally all steel. It is almost the same as the lock body that comes with the engineering door. It only realizes the functions required for the fingerprint lock. Some locks are just the guide piece. I got a stainless steel and wrote a 304 mark, but in other places, what kind of material or material? As for what lock body you put, it is definitely a price. The lock within a thousand dollars is generally not willing to give you a full steel lock body. More than a thousand, it depends on the manufacturers, and even the agents, because the ex-factory price of many lock factories is not including the price of the lock body, the lock body money is calculated. The material of the fingerprint lock, the vast majority is zinc alloy, a small part is stainless steel, and the low end is aluminum alloy, this is to cut corners too much. Now some door factories, in order to sell the door, buy a door to send fingerprint locks, most of them are such aluminum alloy locks, even if there are some other materials, it will certainly not be a good lock, send things, can Is it ok? Almost all the door factories are just a door to the door. How many skills and talents can he make locks? I can understand that the locks made in the door are the most famous, but Wang Li’s feelings. Is to keep eating old, that one Wang Li special lock core, sold for so many years still selling, in the unlocking world, specifically for this lock core unlocking tools, too much. Now why the door lock is not safe, because the unlocking tool is flooding, so that the school can be unlocked casually, the unlocking tool can be bought casually, and the teaching video of teaching books can be found online.
Looking back from the material, zinc alloy has the advantage of its plasticity, and it is widely used in various locks. It is relatively ok. The lock factory's cut corners are nothing more than the thickness, the paint process, and even the sound. The material of the zinc alloy is also good or bad. As for stainless steel, because it is more sturdy, but the plasticity is not strong, there are few good-looking appearances. Basically, the stainless steel locks are square and square. The cut-throat is also in the thickness. Some methods are used, some are stainless steel, some It is stainless steel, thin. As for the internal structure of the lock, although the basic principles are similar, but after many of the locks I have opened, a few hundred yuan of locks, more than a thousand, and two or three thousand, there are still significant differences in workmanship. Even some small brands, the industry is famous for plagiarism, more than 2,000, in fact, it is the same as more than 1,000. After the fingerprint lock is disassembled, the interior is bare or closed. If you don't say anything else, this cost is not to grab the market, and the price war lock will do.
Nowadays, the fingerprint lock market has sprung up like a variety of brands, and even the traditional
Home appliance industry has emerged. However, these companies do not have the R&D production capacity of fingerprint locks, so they can find a random one. I made a lock and sold it as an OEM. This kind of thing is really good. I personally think that the result is the same. Because of the production problem, how can the quality be guaranteed? After all, this is not their main business, as if Haier, Midea, Rongshida, etc. I am doing it, I have also seen Chint Electric, this switch is also doing locks, and even Wrigley, this is also doing locks on the toilet, even funny, the Wrigley lock, used with my door for many years The brand-name locks that existed before were exactly the same, and there was more branding than the lock on my door. As for the other locks that come out, it is estimated that there are at least a few thousand in China. How much like this scene is like the Chinese shou machine market, the foreign goods like Samsung Yale are the earliest to do, (although Samsung’s lock actually To China is a bit unacceptable, many components are plastic, it is said that Samsung does not have a fingerprint lock agent in China, domestic is either parallel or fake) and then some domestic locks are not bad quality to do their own brand, the rest The most, the previous cottage machine, some similar to the fingerprint function maker of the previous MediaTek, the lock factory only used its own appearance to open a model, many of which are common to a few brands.
The price of the mold for the lock is also much worse. Some lock factories have a complete set of designs, and the molds cost one or two million. Some have a mold of only 100,000. Open a good model, find a solution, you can do the lock. However, the current fingerprint scheme can be as few as the technical strength of MediaTek. Only now are all doing their own brand, even if they copy the design of others, they must put on their own logo, recently there is a plagiarism, Yongkang a factory copying the lock of Manshen, plagiarizing this lock Home, but this company, but also run Jingdong to engage in crowdfunding, and then find Wu Jing to endorse, this time Manshen never called, and now ran out to say that others plagiarism, to fight a lawsuit, it is estimated that no use. Today's enterprises are increasingly brand-oriented, but there are too many brands, probably because of the lock-up market, unlike the past, they have license control.
Fingerprint lock this thing, will certainly become more and more popular in the future, the price will also decrease, but after all, it is not the kind of thing used by the shou machine. (The door lock needs special person to install, although many door locks are very simple to install. But we Chinese are not as strong as many foreigners. It is estimated that for a better lock, the price will not drop too much. And the lock that is almost the same, after all, will not consider the cost of after-sales, so it should be more difficult. The functional aspect of the fingerprint lock, the basic is the unlock function, and then the depth is the security aspect, such as unlocking reminder, remote alarm and other alarm functions, and then deep into the future with the future smart home linkage, such as opening the door, automatically lighting Wait, but when can you really spread to the era of smart home for all? I guess, it depends on when the people don’t have to pay most of their income to pay the mortgage. If the people have no money, they won’t buy anything else. Far away. So buy a fingerprint lock, it is recommended that you choose a company that is guaranteed to be sold in the local market. All aspects of the fingerprint lock are well understood and then selected. After all, like buying a car, buy a lock, although it will not accompany you for a lifetime, at least will accompany you for several years. Let's buy a car and change it for a few years, and some will be scrapped for more than ten years. Maybe one day in the future, people will change their locks as hard as the Shuo machine. The quality will pass, and the rest is the value of the face. After all, it’s better, it’s two or three thousand, and it’s a good domestic shou. The same machine. The above viewpoints are purely personal opinions. As for the question of some brands, it is just my personal opinion.
