[Preface]

　　My rural hometown has just been turned over recently, and it is now in the final stage of renovation. Affected by the epidemic, it took half a year from foundation laying to completion. Rural life in Beijing has a lot of ease and comfort that many city people can’t experience, but there is also a problem that public security is not as good as that in the city, so every family has installed advanced security doors.

　　However, the relatively safe security door has also caused some obstacles for me to enter the home. So is there a product that can not only have strong security, but also allow me not to look for the key against the security door? Until recently I saw the D100 smart door lock launched by Aqara!

　　"Appearance introduction"

　　Aqara

　　The D100 automatic intelligent push-pull lock is very heavy to lift, and the packaging adopts simple primary color cowhide carton, which looks more environmentally friendly. It is a millet eco-chain product, which is directly inserted into the C-class mechanical lock core, and can be opened by means of fingerprints, passwords, NFC cards, etc., making it more convenient and humanized to use.

　　When purchasing Aqara D100 smart door lock, it is necessary to measure the size of the guide piece of the original security door at home and give it to the customer service, and then the merchant provides the guide piece with customized size.

　　The packaging adopts a double-layer structure, the upper layer has two handles, the inner and outer, and the lower layer has a C-class mechanical lock core, a guide plate, a battery, a charging cable and a number of hardware accessories.

　　There are two switches on the handle inside the door, and the lower knob is an emergency unlock button, which is purely mechanical. If the battery runs out of power or in an emergency, it is recommended to use this unlock. The buttons above are electronic lock and child lock knob. Users with children at home must find this function practical.

　　The handle on the outside of the door integrates the key opening of the mechanical lock core, NFC sensing area, password input keyboard, fingerprint identification and doorbell from bottom to top. In particular, the addition of this doorbell eliminates the trouble of installing extra doorbell in daily use.

　　Mechanical locks will definitely not be commonly used after installing Aqara D100 smart door lock, so Aqara hides the keyhole intimately, and it is necessary to press the round hole to eject the stopper and rotate it counterclockwise to insert the key.

　　Aqara with protective film removed

　　The D100 smart door lock is very beautiful. The front of the handle is as crystal clear as suet jade because of the mirror panel with IML technology, and it emits oily luster, and it is very hard to scratch.

　　The side of the handle adopts high-precision electrophoresis technology, which makes the surface not easy to fade and feels delicate and quite round. Holding the handle to open the door can bring a tall feeling.

　　In order to strengthen the connection and enhance the three-proof ability of the door lock, Aqara also uses a silicone sealing ring at the connection part between the door lock handle and the metal security door, which will last longer than rubber.

　　The inside handle cover plate of Aqara D100 intelligent door lock is removable, and the two buttons used for setting and the battery compartment for installing lithium-ion batteries are hidden below.

　　The battery compartment has an independent cover plate to prevent the battery from accidentally falling off when the outer cover plate is opened, which is very humanized. The battery used is a 2480mAh high-capacity lithium battery provided by Guardian Power Technology, which has a long battery life and supports 10W fast charging.

　　Mechanical and electronic integrated lock body, in which the cable is used to connect the control computer of the door handle and is opened by fingerprint password.

　　The key and mechanical lock cylinder are in independent disposable packaging, which effectively prevents bad people from copying the key information in advance. Because you don’t usually use a key to open the door, it is a folding design, which is convenient for storage.

　　[Installation process]

　　The installation process is particularly difficult, so it is strongly recommended to contact the official master for free. I just want to record the process before I install it myself. First, install the customized guide plate on the lock body, and then install the positioning rod in the hardware into the handle.

　　Custom guide vanes should also be installed at the door frame, and the lock body and lock core with guide vanes should be installed in the door to see the compatibility with the existing openings.

　　The compatibility between the original opening and Aqara door lock is very unfriendly. After careful study, it is concluded that the door panel needs to be reamed. Use an angle grinder to cut off the part that blocks the installation of the door lock. During this period, there is no time to take pictures. So if you don’t have such super hands-on ability, it’s still recommended to let the official installation master come to your door, and it’s free.

　　In order to adapt to the security doors with different thicknesses, the square column provided by Aqara is very long, and it needs to be cut short by itself after measuring the actual length, and also needs professional tools.

　　After adjustment, fix the inner and outer handles with nails and install the battery, and then test the smoothness of mechanical unlocking on the inner and outer sides. Remind everyone that if you install it yourself, don’t close the door during the test.

　　Cover the upper cover of the handle on the inner side of the door, and the installation is over. Seemingly simple, the actual operation process is really very difficult, and the whole installation time is more than 6 hours. If it is not my powerful hands-on ability, I will really be in big trouble. During the installation, I consulted the official installation master of Aqara, got some technical guidance, and was told that they could fix this door lock in less than an hour.

　　[Experience]

　　Because Aqara is a brand in the Xiaomi ecological chain, you can use the Mijia APP in your mobile phone to connect Aqara.

　　D100 smart door lock enters the settings page. In addition, it also supports Apple’s homekit function, which can be perfectly suitable for Apple’s mobile phone to remotely control and access the door lock.

　　After the initial connection, you will be prompted that there is a new version of firmware to update, and update it decisively for safety reasons. The update process is very fast, and it will take about two or three minutes to complete.

　　No user is bound for the first time, so the first step is to bind the user and set the password. Of course, the administrator user is himself, and besides, you can add almost unlimited users. The password can support up to 10 digits in length and more than 10 billion combinations, and the door lock will lock the keyboard for 15 minutes as long as it detects five consecutive input errors and push it to the user through the app. It is worth mentioning that the D100 smart door lock also supports the 20-digit virtual password function, and any number can be entered before or after the real password. The door lock can be successfully unlocked as long as the continuous and complete password is detected, thus avoiding the potential risk of entering the password face to face when you arrive home with others.

　　After adding each user, you can enter the fingerprint one by one. You need to press different fingerprint parts of your finger seven times in a row, which is basically the same as the setting on Apple’s mobile phone.

　　In addition to password+fingerprint identification, Aqara D100 smart door lock also supports NFC door opening mode. However, the only devices that support NFC are mi band 345, Xiaomi mobile phone and Aqara.

　　NFC card, relatively speaking, fingerprint is more convenient.

　　Of course, as an intelligent door lock, the log function is essential, through which the user information can be recorded in detail every time the door is opened and closed, and every move at home can be monitored in detail. Of course, D100′ s intelligence is not only that, but also a one-time temporary password can be set through the app, and even a time can be specified to run according to predetermined rules, which can more conveniently take care of users with nannies at home.

　　"True automatic lock experience"

　　Aqara

　　D100 intelligent door lock has the function of automatic locking. When the door is closed, the door lock will automatically lock, so it is not necessary to lock it with a key like a traditional mechanical lock. Greatly improved the convenience and put an end to forgetting to lock when going out.

　　It takes only 0.5 seconds to unlock the door with fingerprint, and the recognition rate is very high, and the efficiency of opening the door is far stronger than that of traditional mechanical door locks. And you don’t have to worry about forgetting your keys.

　　When the password is input, the real password can be covered by the multi-digit virtual password, which improves the safety of the door lock when it is used.

　　When unlocking from the inside of the door, you only need to press the unlock button gently. Because the lock is fully automatic, the default state of the door lock is completely locked, and the security is very high.

　　[Full text summary]

　　Experienced Aqara

　　After D100 intelligent push-pull lock, we can’t help but sigh that everything can be intelligently networked. In the new countryside where old ideas are abandoned, we can also enjoy the rapid progress of life brought by scientific and technological progress. A variety of unlocking methods no longer need to worry about the painful picture when forgetting to bring the key. The efficient fingerprint identification module can provide a fast and smooth door opening experience. The reminder of not closing the door and the perfect unlocking log have strong security guarantee in daily use, and you can feel at ease even in the big countryside. With Aqara,

　　After the D100 smart door lock, I became the most beautiful boy in the village. At present, Aqara fully automatic intelligent push-pull lock D100 has been launched in Xiaomi Youpin, with the original price of 2,299 yuan, and the first launch only needs 1,799 yuan, which is very good value.

　　Smart door locks have now entered thousands of households, especially when you brush your face to open the door, so that you can really go home without feeling. As long as you stand at the door, the door lock can identify the owner and automatically open the door, eliminating the operation of pressing your fingers, and truly liberating your hands and taking more things at home.

　　The smart door lock that was originally thought to be unlocked by "brushing face" is very "tall". Who would have thought that "brushing photos" could also unlock it? This is because in the early days of face recognition smart door locks, most products used 2D face recognition technology, which brought many security risks to everyone.

　　Let me tell you now, how does the current smart door lock judge that it is a "real face"?

　　Nowadays, face recognition technology has changed from 2D to 3D, and a thermal imaging face recognition technology, namely 3D face recognition technology, has been applied to smart door locks.

　　This technology mainly produces and analyzes facial images by analyzing the thermal radiation generated by facial blood, which is unique and not easy to be covered up and forged by makeup, and solves the security hidden danger of the dummy’s face unlocking.

　　How to prolong the life of smart locks, Laiwu Century City Unlocking and Lockchanging Company, Laiwu Lockchanging Telephone.

　　Many users have complained that smart locks are easy to break and have a short service life. That may be caused by our improper operation. Today, Xiaobian will correct the five misunderstandings in the daily use of smart locks and easily extend the service life of smart locks.

　　Lubricating oil is not added indiscriminately.

　　According to the relevant national standards, smart locks must have spare mechanical lock holes. However, in the process of daily use, mechanical keys are rarely used by users because of their inconvenience. When it is not used for a long time, it is possible that the lock key is not inserted and removed smoothly.

　　At this time, users often think of adding lubricating oil for the first time, which is actually a wrong practice. Because the oil is easy to stick to dust, after refueling, it is easy to accumulate dust in the lock eye and form greasy dirt, which makes the lock more prone to failure.

　　The correct way is to put a little graphite powder or pencil powder in the lock core slot to ensure the key opens normally.

　　Open the lock yourself, and something may happen.

　　Consumer electronics experts often do it themselves, dismantle mobile phones, dismantle computers, and even want to dismantle smart locks. The reason why this is listed as a wrong practice is because the failure rate is as high as 90%!

　　Unprofessional disassembly is prohibited. The internal structure of fingerprint lock is often much more complicated than the traditional lock, which contains a variety of high-tech electronic products. If you are not familiar with it, you’d better not disassemble it casually.

　　Basically, if you have any questions, you can consult the manufacturer, and there will usually be special after-sales service personnel to help you solve them. This is also to remind you that when buying, it is best to choose a lock manufacturer or agent with good after-sales service to buy fingerprint locks.

　　Light! Light! Gently clean

　　Fingerprint and password unlocking are two unlocking methods that we use frequently every day, but their popularity also means that there is frequent direct contact between the panel and the hand. The grease secreted by sweat glands on the hand is easy to leave stains on the panel, which will accelerate the aging of fingerprint reader and input panel, resulting in recognition failure or insensitive input.

　　Therefore, in order to ensure the quick response of fingerprint and password unlocking, we need to clean the fingerprint head and input panel regularly. When cleaning stains, be careful to use dry soft cloth to wipe gently. It is forbidden to use wet or hard things (such as iron shavings) for cleaning to avoid water or scratches.

　　Close the door gently, it is afraid of pain.

　　Smart lock products have automatic locking function, so some users often push the door directly to the door frame after entering the door, so that the lock tongue and the door frame can have the most intimate hug. When cutting and closing the door, the force is on the door, which is easy to cause the damage of the door lock.

　　The correct way is that when we close the door in the house, we should gently close the door and the door frame, and then let go after the two are attached. Don’t slam the door hard, otherwise the service life of the door lock will be shortened.

　　Always check the battery, there are surprises.

　　Battery is the energy guarantee for the normal operation of smart lock, and it is also an important part of the safe use of smart lock. In daily life, users need to check the battery from time to time, especially in summer or in hot weather. If the battery is found to be too low or prone to leakage, it should be replaced with a new battery immediately to prevent the battery leakage from corroding the smart lock.

　　When selecting batteries, in order to prolong the service life, it is recommended to choose alkaline batteries, and be careful not to mix old and new batteries. From the point of view of fire safety, this is because lithium batteries are prone to explosion at high temperature. In case of fire, the door lock may be locked and the door cannot be opened in time, which will bring more trouble to the rescue.

　　The above is the misunderstanding of the use of smart locks. Don’t spit out that the service life of smart locks is short, because we didn’t take good care of it.

　　Laiwu which fingerprint lock? Which fingerprint lock in Laiwu has good quality?

　　Recently, Lenovo’s smart door lock X1 attracted everyone’s attention because it won IDEA 2019 IDEA Award in the world-renowned 2019 IDEA Industrial Design Awards Ceremony.

　　You know, IDEA, IF and RedDot are the authoritative awards of the world’s three major industrial design awards, and IDEA is also known as the "Oscar in the industrial design field". Every year, tens of thousands of works participate in the election, and only about a hundred works win the honor, and this is the first time that a domestic brand has won the smart door lock of the IDEA Award. The Lenovo smart door lock X1 can stand out among tens of thousands of entries, which shows that its innovative design products have been recognized by international authorities.

　　Xiaobian was also lucky enough to get the Lenovo smart door lock X1, which made Xiaobian fondle admiringly, from simple and fashionable appearance, product technology and materials to near-perfect safety experience. Today, I would also like to introduce this simple, trendy, safe and reliable Lenovo smart door lock X1.

　　The art of flowing on the door panel of the integration of humanities and industry

　　In this face-oriented society, choosing a door lock, of course, depends on the face value first. However, there is definitely no pressure on Lenovo smart door locks that won the IDEA 2019 Industrial Design Award.

　　Simple control panel, simple and elegant body, handleless design and flowing metal shape make Lenovo smart door lock X1 a natural work of art..

　　It is reported that the industrial design of Lenovo intelligent door lock X1 comes from the design team of Beijing Olympic Torch. They believe that any complex technology should not give users a sense of estrangement. Xiao Bian also thinks that excessive product design will be a bit overwhelming, and the combination of the door and the lock will be too abrupt. The simple, fashionable and trendy Lenovo smart door lock X1 will bring you a sense of sight that the lock is integrated into the door. This kind of extreme comfort can’t be given by other smart door locks.

　　Lenovo Smart Door Lock X1 provides three different color versions, namely Obsidian Gold, Danchi Copper and mocha brown. Users can choose according to their own preferences, and the three different colors can adapt to most decoration styles.

　　Convenient unlocking in various ways to cover all application scenarios.

　　Intelligent door locks, of course, the most important thing is to give people a smarter and more convenient way to unlock. Lenovo smart door lock X1 provides almost all common unlocking methods of smart door locks, including passwords, fingerprints, encrypted cards, remote temporary passwords, double authentication unlocking and mechanical emergency keys, covering almost people of different ages and different application scenarios.

　　In the actual experience, the most surprising thing for Xiaobian is fingerprint identification and remote temporary password unlocking.

　　In the process of fingerprint unlocking, it can be clearly felt that the fingerprint recognition area of Lenovo smart door lock X1 is larger than that of similar products tested before, and it is also very convenient to press. Coupled with the background light, it can be easily pressed at one time even in a dark environment.

　　Because Lenovo smart door lock X1 uses Swedish FPC capacitive semiconductor fingerprint sensor, plus the double fingerprint algorithm, the speed of fingerprint recognition is really fast, and the feeling of opening at the touch of a button is the feel of future technology.

　　Lenovo Smart Door Lock X1 also supports the identification of living fingerprints. After testing, Lenovo Smart Door Lock X1 can effectively identify real fingerprints and counterfeit fingerprints, perfectly avoiding the risk of unlocking with fake fingerprints.

　　Although the use frequency of remote temporary password is low, it can play an important role at critical moments. Before Xiaobian rented a house, it was an electronic password lock. Once we went on a business trip to participate in an activity, we remembered that we had an appointment to clean the room. We had no choice but to tell Aunt Cleaning the unique password. If we want to change the password, we need to ask the landlord for the management password. It is really troublesome, but with the remote temporary password function, this problem is not a problem.

　　Multi-security real-time alarm is smarter.

　　Smart door locks give us wisdom and convenience, but they are also safe and reliable. Lenovo smart door lock X1 has as many as 17 security protections, which is a unique high-end configuration at the same price.

　　At present, most smart door locks use mechanical locks and electronic clutch locks, while Lenovo smart door lock X1 uses a rare full-automatic lock, which automatically locks when the door is closed, without manual operation, greatly improving the safety of the home.

　　In our daily life, we all have the habit of holding the door by hand, thinking that it is locked, but often the door is left unlocked, which will bring very serious security risks. In view of this scenario, Lenovo smart door lock X1 is also equipped with the function of closing the door. If the door is left unlocked, it will give the user a safety reminder that the door is not closed, which is really a practical function.

　　In addition, as we all know, the automatic lock body and the hook of heaven and earth can’t have both, because most of the automatic lock bodies and push-pull smart door locks on the market don’t support the hook of heaven and earth. In the eyes of many users, the smart door lock that does not support the hook of heaven and earth means insecurity.

　　Thanks to the technological innovation of Lenovo’s R&D team, Lenovo’s smart door lock X1 is one of the few smart door locks that can support the heaven-earth hook, and it can adapt to most standard lock bodies in the market. This not only broke the technical deadlock in the industry, but also dispelled users’ doubts about the insecurity of smart door locks.

　　The X1 lock core of Lenovo smart door lock adopts the C-level plug with the highest safety factor, and it is a fully isolated lock body, which is anti-pry, anti-saw and anti-collision … Even if the panel is broken, criminals can’t open the door, which fundamentally ensures the safety of the door lock.

　　Xiao Bian tried to open Lenovo’s smart door lock X1 with the "black box" (the master key of smart lock), but the prompt sound and light of the door lock ruthlessly rejected the "black box", and the door lock did not open and there was no crash, indicating that its anti-"black box" design played a role.

　　Of course, in addition to preventing the "black box", Lenovo smart door lock X1 also has various protective measures such as cat’s eye theft prevention, prevention of children’s misoperation, false password, anti-hijacking, remote alarm and so on.

　　Xiao Bian thinks that virtual password, anti-trial-and-error self-locking, anti-hijacking, and remote alarm are practical functional designs that really focus on ensuring users’ home safety.

　　Among them, virtual password is my favorite function. I often ask my friends to be happy together, but when I open the door, it is not convenient to ask my friends to avoid me. This is when the virtual password comes into play. Just add some numbers before and after the original password and open the door directly, which avoids the embarrassment of both parties.

　　When someone maliciously enters other numbers and tries to unlock them, they will also lock themselves because of repeated trial and error. After Xiaobian entered the password for five times in a row, the password lock entered a self-protection state, and the "Smart Lenovo" APP pushed me a safety reminder;

　　Although the door lock will lock itself after repeated trial and error, the user can still unlock it by other unlocking methods, which is also a relatively humanized small design to avoid the situation that when the door lock locks itself due to forgetting the password, it has to wait outside the door to unlock it.

　　The anti-hijacking function is also an essential security guarantee for single women. When you open the door, if you are held hostage by criminals, you can use the anti-hijacking fingerprint or password to open the door, and you can also achieve the purpose of remote alarm and help without angering criminals.

　　In addition, the door lock is pried and the remote alarm of abnormal situation allows us to control the state of the door lock at home in real time … Everything is under control, and this sense of security is even more secure than that given by a boyfriend/girlfriend.

　　Smart Lenovo APP makes smart life at a touch.

　　By setting different smart life scenes, intelligent products are linked to bring people the most personalized, intelligent and convenient life enjoyment, which is the smart life pursued by users and the direction of major technology manufacturers. As a powerful old technology manufacturer, Lenovo has spared no effort to build a perfect smart home ecosystem, relying on a comprehensive product line and a unified management platform to provide users with the best smart experience.

　　As an important safety protection product of Lenovo, Lenovo Smart Door Lock X1 also uses "Smart Lenovo" APP as the user entrance to control the product and set smart life scenes.

　　In the "Smart Lenovo" APP, users can manage users, passwords and unlock records, and manage locks in all directions.

　　As mentioned earlier, if a friend comes to visit and he is not at home, he can manage the password in the "Smart Lenovo" APP and generate a temporary password for his friends to use; The door lock has been maliciously entered with invalid passwords for many times, the family members have been held hostage to unlock it, and the daily door opening and closing status can be viewed in the "History".

　　Of course, in addition to the management of a single product, the "Smart Lenovo" APP can also realize the linkage of smart life scenes. We can set the modes of "going home" and "leaving home" by ourselves, so that the major smart products in our home can cooperate tacitly and do their own jobs. For example, when you are away from home, you can set up security devices such as smart cameras, door and window sensors, etc. When you leave home, the system will automatically turn on relevant security devices to protect the safety of your home.

　　At present, Lenovo smart door lock X1 has been put on the shelves of major e-commerce platforms, and the official price is 2699 yuan. Among the products with the same price in the market, its design aesthetics, hardware configuration, safety protection and other aspects are very competitive, even exceeding Xiaobian’s expectations.

　　On the whole, Lenovo smart door lock X1 has performed quite well in simple and trendy design, exquisite production technology, up to 17-fold safety protection and intelligent and convenient user experience. Such a cost-effective product may be a good choice for you who like to pursue fashion and experience new technologies.

　　Now families are choosing locks. In order to be safe and more secure, more and more people choose smart locks. The effect of intelligent lock in anti-theft is many times stronger than that of ordinary lock, and now families are willing to use it. For those who agree with Xiaokai smart lock, how about knowing before choosing? And what are the general unlocking methods.

　　1. What is the performance of Xiaokai smart lock?

　　Xiaokai smart lock belongs to a brand, and its market share is relatively large, which allows young people to fully enjoy the convenience and safety of this brand smart lock, reflecting smart life. It is certain that the brand’s smart lock position is young, secure, intelligent and extremely cost-effective. Especially in the aspect of security, it can make the selected users be safe and worry-free from theft in their own homes after installation, so now families are willing to choose Xiaokai smart locks when choosing to install smart locks.

　　2. What are the unlocking methods of Xiaokai smart lock?

　　Xiaokai smart lock embodies diversification in unlocking methods, which can be unlocked in many ways, so it is more convenient to unlock. If you forget the password, you can choose fingerprint to unlock. For example, different unlocking methods include fingerprint unlocking, password unlocking, card unlocking, key unlocking, anti-peeping, anti-prying alarm, and remote control of mobile APP. When in use, you can choose which one can unlock quickly according to your favorite unlocking method.

　　For those who recognize Xiaokai smart lock, we know that there are more brands on the market now, and we also know that the unlocking methods are diversified. For those who recognize this brand, we must buy it in formal channels when purchasing, so as to ensure the quality and avoid spending more money in terms of cost performance.

　　Xiaomi fingerprint lock has ten security protections, such as double induction door opening, five abnormal warnings, and one-button protection when leaving home. It is convenient and practical for the mobile App to control and open the door. Whether you go home by yourself or your family and friends come home, the remote control of the mobile phone will not affect the safety performance. So, which is the Xiaomi fingerprint lock foundry?

　　Which is the Xiaomi fingerprint lock foundry?

　　Xiaomi smart lock products are mostly manufactured by green rice and Luke. Although Xiaomi entered the fingerprint lock industry not long ago, it quickly became the sales leader of the industry with its advantages of high cost performance, rich ecological linkage and strong brand influence, accounting for over 30% of the total online sales.

　　Xiaomi only participates in the design of fingerprint lock products, and produces deer and green rice that are handed over to Mijia ecological chain. Compared with most brands, it is a major feature of Xiaomi fingerprint lock to be linked with rich Mijia household. At present, there are two categories: push-pull type and hand-held type, and the price ranges from 999-1599 yuan. Basically, each one is an e-commerce explosion.

　　The standard version is a classic model with a cumulative sales volume of one million, and it is also the first smart lock of Xiaomi. It is equipped with multiple customized lock bodies for sensing detection and has multiple alarm reminding functions. Other hand-held models are upgraded or simplified on this basis: 1S adds electronic doorbell and NFC unlocking, Pro configures electronic cat’s eye to support real-time intercom of App, and Youth Edition and E are low-profile models with simple functions.

　　However, the most recommended is the Xiaomi face recognition smart lock! It supports the following unlocking methods: password unlocking (long-term password, periodic password and temporary password), face recognition unlocking, fingerprint unlocking, Bluetooth unlocking and key unlocking.

　　So many unlocking methods with APP management can actually accomplish a lot of scene adaptation remotely:

　　When using the password lock, if the courier brother or friend comes over temporarily and you don’t have time to come back, you can set a temporary password for them remotely on your mobile phone, so that they don’t have to wait outside the door.

　　When using the face recognition lock, the biggest advantage is that when we have a lot of things in our hands, we don’t have to spare our hands to press the password or identify fingerprints. We just stand at the door, face recognition unlocks, and the lock body is automatically unlocked. Then we can kick the door open directly with our feet.

　　Or, if you are too lazy to record fingerprints and face data, you can also use Bluetooth to unlock it.

　　Or, if you forget to change the battery, you can unlock it directly with the key. I think that supporting mechanical key unlocking should be the bottom line of all lock products.

　　Other product recommendations:

　　First, Xiaomi Smart Door Lock E

　　Exquisite and compact fingerprint lock, built-in semiconductor fingerprint identification system, accurate identification of different fingerprints, quick unlocking is more convenient. There are six ways to unlock, and the family can choose the right way to unlock. With class C lock core, the safety factor is high. Multiple safety design, riot prevention and technical unlocking.

　　Second, Xiaomi smart door lock 1S

　　The fuselage adopts integrated structural design, and the front and rear panels adopt IML technology, which has good scratch resistance. At the same time, you don’t have to worry about the blackening of the panels after a long time of use, and the internal structure is also very neat. It adopts a fully-detected electronic lock body, and the built-in intelligent sensors with four locking tongues can accurately detect the state of the lock body, and at the same time, it can effectively prevent electromagnetic interference and violent disassembly. The lock core uses a straight-in C-class lock core.

　　Third, Xiaomi smart door lock Pro

　　This smart door lock integrates smart door lock, smart doorbell and smart camera. At the top of the front of the door lock is a 1080p high-definition wide-angle camera with a large wide angle of 161. After connecting to wifi, you can grasp the state in front of the door in real time. The dot below the camera is an illumination sensor, which can detect the light intensity of the current environment and judge whether to enter the night vision function state; The one below, which is similar to the camera, is a human body sensor. When someone stays in front of the door for too long, it will automatically turn on the camera to record the video and push it to the mobile phone.

　　This door lock can be linked with Xiaoai touch-screen smart speaker. When a visitor presses the doorbell, he can check it through Xiaoai, and the mobile phone will also receive the video push of the visit. If he is not at home, he can make a temporary visual call with the courier through the mobile phone. In addition, this one also supports HomeKit. After being authorized to APPle HomeKit through Mijia App, you can open the door by voice through siri.

　　Fourth, Xiaomi fully automatic intelligent door lock

　　The design is very beautiful in science and technology, and the black panel is deep and integrated. It is not easy to lose paint by electrophoretic spraying, supplemented by high-strength alloy body, which is low-key and simple without losing the atmosphere! Indoor cat’s eye-proof design double induction unlocking, you need to press the door opening button and hold the handle at the same time to open the door, which realizes one-button quick opening, which is very humanized and safer. Unlocking methods are also very rich. In addition to fingerprints, passwords, temporary passwords, Bluetooth and keys, it also supports NFC and Apple Homekti unlocking, and at the same time supports Xiaomi IOT and Apple HomeKit dual protocols, giving users one more choice.

　　How about Xiaomi fingerprint lock?

　　Xiaomi’s fingerprint lock configuration is relatively uniform, and the quality is quite good; The evaluation of Xiaomi is that "advantages and pain points" coexist, but it is definitely the brand with the best "user experience" in the same price.

　　Almost every product of "Xiaomi" has brought "electronic product thinking" and "user thinking" to the extreme. It is difficult to find seven products with richer functions and more detailed experience at the same price. It is inseparable from strong supply chain support to achieve such "high energy parity".

　　Coupled with its own brand influence, fan base, and mature smart home matrix system, it has consistently sold TOP1 all the way, and the results can’t deceive people.

　　In the face of huge shipments, it is normal for some bad reviews to occur. After all, even the same batch of products will have some slight differences. Generally speaking, "Xiaomi" can still rank in the middle and upper reaches.

　　Evaluation and analysis on Xiaomi fingerprint lock by netizens;

　　Appearance: tall and very sensitive: this is really a finger-affixed second door opening function design: too multifunctional, buy a gateway to try the material technology: good workmanship, feel is also ok. Other features: good random password, sent directly by people at home: the installation master is very professional, the door body is cut reasonably and installed in place, thank you.

　　Appearance: the degree of integration is very high, and the appearance is very beautiful. Sensitivity: very sensitive, and the master’s training is also in place. Functional design: Many functions, especially linkage with other devices of Mijia Internet of Things. Still exploring. Material technology: I was worried that the cover of the battery was easy to break before, but it was easy to remove after trying it, and the buckle design was more convenient.

　　What about the Greyville smart lock? Anyone familiar with Greville knows that the most intuitive advantage of smart lock products from Greville is its high face value. The Wukong i6H, which passed the technical certification of HUAWEI HiLink ecological products, also continued the fine tradition of Greville’s smart lock with high value.

　　How about Greyville Smart Lock?

　　Gleewell Greevell brand belongs to German Martha Holding Group, and its headquarters was founded in Cologne in the last century. With years of hardware manufacturing experience, German high-standard manufacturing technology, high-level industrial design and perfect after-sales service, Gleewell brand is widely used in many well-known construction projects around the world. It owns three holding companies and a holding factory. Enterprises have more than 100 technical patents (utility model patents, product appearance patents, software copyrights, etc.).

　　First of all, Grievell Wukong i6H adopts a simple, fashionable and atmospheric design style, which is very in line with the aesthetic needs of young consumers. Secondly, Wukong i6H is one of the first smart lock products with leather design in the industry. It is reported that the i6H leather handle is made of imported leather material, and the surface texture is natural, smooth and delicate, which brings users a good feel and touch. More importantly, the i6H leather handle has been continuously tested at -20℃-60℃ for 12 hours, and the test results show that the i6H leather handle is still intact. The application of leather handle makes the door lock more grade and texture; In terms of color matching, Wukong i6H offers three color matching options: Obsidian Black, Starry Grey and mocha brown. Users can freely choose different color locks according to different home decoration styles.

　　However, in the era of looking at faces, more and more consumers join the "foreign trade association". The first factor they consider when spending is the value of products, followed by the quality and function of products. Therefore, products with superior value are often more popular with users. Greville, who has always focused on the field of high-end smart locks, is well versed in this, and its dream wing M9, which is a visible cat’s eye smart lock, is one of the representatives of high-value smart lock products.

　　From the appearance, the dream wing M9 of Greville adopts simple, fashionable and ultra-thin design, which is very in line with the aesthetic needs of consumers. The reason why it can be ultra-thin is that Dream Wing M9 takes the lead in adopting ultra-thin motor in the industry. Although it has increased a lot of costs, it has played a "god assist" role in improving the product value. In terms of handle handling, M9 adopts cross-shaped leather design, which gives users a comfortable grip.

　　High quality-the basis of winning users’ trust

　　High face value can really attract more consumers, but if there is no excellent quality, it should not be able to completely conquer consumers. Therefore, quality is the soul of products and the foundation of an enterprise’s survival. Therefore, as one of the representatives of high-end smart lock brands, Greville has always attached great importance to quality control.

　　High security-visible is safer.

　　First of all, the Grievell Dream Wing M9 has its own cat-eye monitoring function, which can wake up the screen indoors to check the status outside the door, especially when an outsider visits, and then decide whether to open the door after confirming his identity through cat-eye monitoring; Secondly, when the lock is correctly identified, someone rings the doorbell, the lock verification fails for more than 5 times, and the door lock is pried and the anti-theft alarm is started, the cat’s eye monitoring on the door lock can capture the dynamic picture of the door and push it to WeChat WeChat official account, so that users can know the status of the door and the door lock anytime and anywhere.

　　Hi-tech-A variety of convenient unlocking methods

　　1. The older an old man is, the worse his memory is. It often happens that he forgets to bring his key and is locked out. 2. It is extremely inconvenient for the old people to come back from shopping with big bags and small bags, but also to find the key to open the door. It is extremely inconvenient to give their parents a Greville smart lock. There are so many unlocking methods, such as fingerprint unlocking, password unlocking, card unlocking, remote unlocking, etc. There is always one that can help parents open the door.

It is reported that these black technologies are the first application in the industry.

　　It is worth mentioning that Greville has also made a breakthrough innovation in the design of X Axe’s back panel. The design of the back panel is consistent with that of the front panel, which gets rid of the homogenization phenomenon of "the front is different, and the back panel is locked on one side" and brings better visual effects to users.

　　VI. Summary

　　The use experience of TCL fingerprint lock is still very good, and the overall texture is very good. It is more suitable for upgrading the door lock at home, completely throwing away the key, making it lighter to go out every day and more convenient to go home.

　　In the practical experience, this door lock is still great. There are many ways to unlock, such as password, fingerprint, card and mechanical door lock, which can easily meet the needs of different people at home. It is especially suitable for the elderly who don’t quite understand fingerprints and can’t remember passwords. Just like swiping an elevator card, you can easily open the door.

　　The lock core of the door lock is electric, both unlocking and locking are electric, and the action is very fast. The actual experience, just put your finger on it, and the lock cylinder starts to move. The whole process is very smooth and the experience is great.

　　And the door lock supports networking, with what hardware such as cameras, daily express delivery, not too cool.

　　During the Spring Festival, many consumers go home from other places for the New Year. In the meantime, everyone will inevitably go out to visit relatives and friends. If the door lock at home is too "novice", it may leave an opportunity for thieves. In order to feel more at ease during the Spring Festival, many young consumers have replaced ordinary locks at home with smart locks.

　　Then, the question is, how do we care for smart door locks every day? In order to solve this problem, the author has compiled some daily nursing knowledge of users and netizens. I feel it is useful, so I share it with you. Parents in need may wish to have a look.

　　1. Clean the door lock regularly.

　　Although the lock body of the smart lock is very strong, no matter how hard the steel is, it is afraid of corrosion. When wiping the smart lock at ordinary times, be careful not to use corrosive cleaning agents, and in addition, be sure not to use steel wire cleaning balls, otherwise the surface coating may be scratched and the lock body may be easily corroded.

　　Most smart door locks support fingerprint recognition function, and we also need to maintain the fingerprint recognition module every day. Because the fingerprint sensor that has been used for a long time may affect the opening and closing sensitivity of the door lock after being stained with dirt, it should be gently wiped with a dry soft cloth to prevent scratching the fingerprint sensor and affecting the sensitivity of fingerprint entry.

　　At the same time, attention should be paid to avoid using dirty hands or wet hands as much as possible during use. If it is a long-term outing or rainy season, remember to replace the new battery to prevent the battery liquid from corroding the internal circuit.

　　2. Don’t use locks violently.

　　For smart door locks, the handle is the key part to open and close the door, and its flexibility directly affects the use of fingerprint locks. When using it, you should avoid pulling it vigorously, don’t let children pull it to play, and don’t slam the door when opening and closing the door. In addition, the LCD screen of the smart door lock should not be vigorously pressed or knocked, and should not be scratched with hard objects or sharp objects.

　　The fingerprint identification module of intelligent door lock is a very sensitive electronic device, which should be used correctly. At present, many fingerprint locks can identify fingerprints by gently holding the handle. When the identification is successful, the door can be opened by gently pressing the handle, and repeated hard pulling should be avoided.

　　3, maintenance to find professionals.

　　The internal structure of the intelligent door lock is much more complicated than that of the traditional mechanical lock. When installing or maintaining, it must be handed over to professional installers to ensure that the space reserved between the door and the door frame, the lock body and the door panel is reasonable, so as not to cause mismatch between parts.

　　The warranty period of smart door locks is generally 3 years, and if there is any fault during this period, you can invite the after-sales master to come to the door for repair for free. In daily maintenance, in addition to the correct operation of the smart lock, users should also regularly check the electronic lock core, anti-theft lock body, clutch, handle and other key transmission parts of the smart lock to ensure that the smart lock maintains a good technical state and protect family safety.

　　4, the battery should be replaced in time.

　　Nowadays, due to technical and cost reasons, the life of most batteries used in smart door locks is limited. Therefore, it is necessary for users to regularly check the power consumption of batteries (not more than once every six months).
