The car stopped at the door, the car keys were on me, and there was no sound. After one night, the car suddenly disappeared. On October 26, Xiaolan police reported that a "bizarre" theft of a vehicle was quickly cracked.

　　On the morning of October 22, Mr. Zou, a resident of Xiaolan, reported to Yongning Police Station that the Toyota car parked near his door the night before was stolen. He remembered it clearly and decided to lock the door before leaving. He didn’t hear anything at night, but he found that the car was gone early in the morning.

　　On the evening of October 23rd, the police of Yongning Police Station arrested the suspect Liu Mouhua in a rented house on Min ‘an North Road in the north area of Xiaolan Town, and found the key of a Toyota car from him on the spot, and seized the stolen Toyota car near the rented house.

　　After the trial, the suspect Liu Mouhua confessed the criminal facts of car theft. It turned out that one day a year ago, Liu Mouhua picked up a car key, but he didn’t find a way to give it to the owner, but stayed and played a "small abacus." After a period of time, Liu Mouhua used the electronic remote control of the car key to find the car near the road where the key was found, but he never started.

　　In October this year, Liu Mouhua was short of money and had the idea of stealing vehicles. On the evening of October 21, Liu Mouhua went out with the car keys, and soon found the parking position of the car. When no one looked around, he drove the car away. Liu Mouhua did not dare to drive back to his hometown, but parked near the rental house, ready to wait for an opportunity to shoot. Unexpectedly, 48 hours later, the police came to the door.

　　At present, the suspect Liu Mouhua has been under criminal detention and the case is under further review.

　　I don’t know which smart door lock is recommended for my friends. We all know that traditional door locks also have their own aesthetic characteristics, but if you forget to bring your key when you go out, you have to wait helplessly and your family will come over to unlock it for you. It’s really embarrassing.

　　So now that smart door locks are widely popularized, smart door locks are no longer the exclusive label of high-end users, and every household can have such a smart door lock to improve the quality of home life.

　　We all know that the most practical convenience of choosing a smart door lock is that you don’t have to worry about forgetting to bring your key, a fingerprint, a string of passwords, an NFC card or a mobile phone when you go out. This is the most practical advantage of a smart door lock.

　　After installing Xiaomi smart door locks in my home, if my friends want to start, they will generally recommend buying them. Today, I recommend two smart door locks 2S for my friends. For Xiaobian who loves to do it, how can I let go of such a good practical experience? So I prepared all the tools to share with you how to install a smart door lock! (This practical demonstration is risky, so please don’t operate it for non-professionals.)

　　First of all, let’s take a look at the characteristics of this Luke smart door lock.

　　Portable kraft paper is used in the packaging. After unpacking the packaging box, the double-layer foam pad is used inside, which well protects the transportation safety of the door lock. It contains a pair of front and back locks, a box of corresponding accessories for the lock body stopper, a picture of the opening size, eight batteries for the fifth battery and instructions.

　　We noticed that the smart door lock is similar in fact, and it looks similar in appearance and has its own characteristics. We saw that this smart door lock is only available in black, with ultra-thin zinc alloy panel, and the front panel is bar light, password area, NFC sensing area, fingerprint handle and keyhole area from top to bottom; The back panel is the battery area, which is matched with the reset button, the door handle and the anti-lock button.

　　Functionally, this Luke smart lock can automatically lock the door without lifting the doorknob lock, which is very suitable for obsessive-compulsive disorder and amnesia. Choose clutch built-in electronic lock body, made of stainless steel, even if the panel is damaged, it can not be unlocked immediately, and the safety factor is excellent; Five safety sensors, always warning the abnormal situation of door lock; C-class plug-in core has explosion-proof disassembly ability, which makes home safer.

　　Knowing the door lock in general, we will start our actual installation demonstration of the door lock today. So what installation tools should we prepare?

　　Specifically, you need to prepare these: cutting machine/metal slicing/electric screwdriver/Phillips head/rivet/rivet gun/metal drill/black marker.

　　The installation operation flow is as follows:

　　◇ Because the door to be installed didn’t carry out laser hole digging in advance according to the size chart of the opening, it is necessary to mark the door according to the size chart, and then pick up the cutting machine to cut the marked position. Pay attention to hold the cutting machine tightly when cutting to ensure safety. If you want to stop, you must turn off the cutting machine switch in time;

　　◇ After expanding the hole, according to the right door opening direction, rotate the lock body clockwise with the door bolt, then take out a small screw next to the door bolt with a screwdriver, and then put the lock body in the door position, and check again whether the circuit attached to the lock body is aligned, whether the expanding hole is in place, and whether it affects the installation of the panel. If it is, it needs to be revised. Then dig a hole with a metal drill against the four screw positions of the lock body, and fix the alignment with rivets correctly.

　　◇ The default door lock is the right door opening direction, so check again whether the front and rear panel locks are in the right door opening direction, and cut the length of the door bolt and the panel fixing screw cap according to the thickness of the door, so that the front and rear panels can fit together;

　　◇ Put the lock core, lock the screws, connect the circuit wires of the front and rear panels respectively, remove the rear panel, and lock the door against the two screw positions;

　　◇ Then push the door lock to the position close to the hole of the side panel, check whether the position of the side panel corresponding to the idling square steel of the lock tongue is consistent, then use a cutting machine to cut and modify the side hole, then use a metal drill to dig holes at the four screw positions of the side panel, and then use a rivet gun to punch rivets into the screw holes;

　　◇ Then close the smart lock from the door, check whether it opens and closes normally, take out the mobile phone to download Mijia App, open Bluetooth to bind the smart door lock, set the security password, and record the administrator fingerprint password and other ordinary user fingerprints;

　　◇ Normally, you need to configure a separate Bluetooth gateway to communicate with the smart door lock, check the door lock status and set the temporary password for visiting, and finally switch the door lock several times to ensure that the smart lock is installed and the door is opened and closed normally.

　　How to watch the actual demonstration, do you have a certain understanding of the installation of smart door locks? If you have certain professional skills, I believe that a successful door lock installation experience will benefit you a lot. Well, hurry to buy a lock!

　　How about Jiabeitong smart lock?

　　In terms of design, Jiabeitong smart lock is naturally unwilling to be vulgar. The style with a sense of science and technology, with a calm appearance and smooth lines, makes the whole body look high-end and atmospheric. As for the fuselage, the whole fuselage of Jiabeitong smart lock series is made of aluminum alloy, with baking paint technology, which is comfortable to touch, light, hard and wear-resistant. At the same time, this product has two colors to choose from, and the simple lock body design makes it popular among young people.

　　The built-in intelligent cat’s eye of Jiabeitong intelligent lock can realize remote visual call function. When the host goes out and visitors come to the door, they can ignore the distance and realize one-click video communication. This product adopts fully automatic electronic lock body, and the sound of opening and closing the door is small. At the same time, the built-in motor will automatically lock the door after it is closed. The convenience brought by technology is obvious.

　　Visible cat’s eye screen, safe and real-time visible outside the door

　　In order to create personalized, cutting-edge smart door lock products and meet the diverse needs of users, Jiabeitong smart lock integrates the core video technology in the product form of ordinary smart locks, which increases the intelligent use scene compared with the door-opening role played by smart locks. On the basis of ordinary smart locks, the visual cat’s eye smart lock optimizes the functions of fingerprint, anti-theft and so on, supplemented by visual functions, and is a 24-hour visual guard for families.

　　Multi-dimensional living fingerprint recognition

　　Multi-dimensional living fingerprint identification function, including fingerprint, skin, blood and other multi-dimensional living fingerprint identification, verifies user fingerprint information, effectively identifies and rejects fake fingerprints. Jiabeitong smart lock has 1.2 times the fingerprint recognition of ordinary fingerprint lock, 360-degree fingerprint storage, 500DPI ultra-high recognition rate, finger touch, automatic retraction of lock tongue, no need to push and pull, and directly open the door. The hidden fingerprint head can effectively prevent scratch damage and protect the core components from the structure.

　　Super run interior texture, perfect combination of technology and art

　　Craft and design have never been the decisive factors for consumers to buy a lock, but they can also become two heavy ones when they are done. Jiabeitong smart lock’s exquisite craftsmanship and elegant design all highlight its craftsman spirit. The appearance design adopts full curved surface design, the whole panel brings visual extension through streamlined shape, and the beautiful radian is more ergonomic. The front and rear panels are made of zinc alloy plus surface frosted material, which improves the wear resistance and corrosion resistance of the surface, prolongs the service life and makes the product more textured and feel.

　　Jiabeitong smart lock WiFi function

　　Jiabeitong wifi smart door lock is very different from the traditional mechanical door lock, which can be remotely controlled by mobile phone. In other words, as long as we install a remote control system on our mobile phone, we can automatically open the door by operating the mobile phone in advance when we go home. Some people may say that if we change our mobile phones, we won’t be able to open the door unless it is the door. In fact, this is a great advantage of the wifi smart door lock. As long as our mobile phone is iphone or Android, it can be installed. When installing, set the password so that you can enter the password to open the door lock before going home.

　　Chuangsheng intelligent lock features

　　1. Ultra-low power consumption: four 5th batteries can be used continuously for 270 days.

　　2. Human body infrared+Bluetooth sensing technology: near the distance of 0.8 meters, it automatically senses the matching of mobile phones and wakes up the mechanism to prepare for unlocking.

　　9. Alarm function: When an unauthorized person attempts to open the door lock, an audible and visual alarm will be given to ensure home safety.

　　Generally speaking, adding WiFi module to the smart lock not only ensures the stability of door lock networking, but also reduces the use cost to a certain extent. There is no need to install a gateway separately, which reduces the space limitation. The setting method similar to mobile phone networking can also make users get started easily, and the operation is simpler.

　　Jiabeitong Smart Lock, OK?

　　Jiabeitong fingerprint lock is well configured, with fast identification, 192×256 large-area fingerprint collector and AI self-learning algorithm, which makes fingerprint identification more and more convenient and sensitive, and can accurately identify four groups of children.

　　Jiabeitong smart lock does not hesitate to spend money, and the key parts are all made of stainless steel, which is rare in the industry. It has excellent impact resistance, corrosion resistance and wear resistance, and its mechanical strength and stability are much higher than those of the popular alloy locking tongue in the market. The structure between the lock tongue and the lock hole is seamless and perfectly matched, and no object that maliciously destroys the door lock can be inserted; In addition, its bearing capacity is greater than 6000N, which is enough to prevent the deformation of the lock caused by external human violence, and greatly improve the service life and safety performance of the smart lock.

　　Facing the fact that most locks in the market are using B-class lock cores, Jiabeitong’s smart locks are already using self-developed super-B-class smart lock cores, which are more complicated in structure. Double-row marble grooves are used on both sides, and the concave-convex position of the key body is matched with a variety of special-shaped marbles, and at most billions of key codes can be compiled, which increases the difficulty of unlocking. Technical unlocking takes at least 270 minutes, which is enough to keep criminals out of the door. If the super-B lock core is opened by force, the inside of the lock core will be destroyed, the lock core will automatically lock the system and give an alarm sound.

　　1. A variety of convenient unlocking methods in all directions

　　Jiabeitong fingerprint lock abandons the criticized traditional manual key unlocking, and adopts more convenient unlocking methods such as remote control unlocking, mobile phone pp unlocking, fingerprint unlocking and password card unlocking. This not only saves time and effort, but also satisfies your "laziness" to the maximum extent, allowing you to calmly deal with the following situations! So that you can "lazy" with the key from now on!

　　2. Omni-directional quick locking and quick opening

　　Jiabeitong fingerprint lock adopts the most cutting-edge fashion "double fast" design concept. When going out, the unique escape function design allows you to quickly unlock the functions of oblique tongue, square tongue and safety tongue by pressing the handle inside the door; After closing the door, just lift the handle up slightly, you can lock the anti-theft tongue and leave home with confidence. When you go home, gently point your finger. Advanced fingerprint algorithm helps you open the door. Welcome home! It is so smart! Let your "lazy" rest assured, "lazy" comfortable, "lazy" romantic!

　　3, temporary users, nanny function

　　I hired a nanny at home and had to authorize her to open the door, but many nannies may be recruited by domestic companies. What should I do if I am not familiar with the foundation? What if I change my nanny? What should I do if I drop the remote control key? With the Jiabeitong fingerprint lock, you can be lazy and worry about it! Jiabeitong fingerprint lock is equipped with data query system, which can upload or download the unlocking record of fingerprint machine to the computer for easy query and tracking!

　　How about Jiabeitong smart lock? Personally, I think it is good! The emergence of Jiabeitong smart lock is undoubtedly another innovative design to free hands. In the future, Jiabeitong smart lock will strive to become the leader in the industry, make the most attentive products and provide better service, both in appearance design and function expansion. I believe that in the near future, Jiabeitong smart lock will become the first choice for thousands of families by virtue of its own strength, so that more people have a special liking for it.

　　Intelligent door locks are based on different components and involve different encryption technologies. Here, we will briefly talk about the types of encryption technologies used, such as the front and rear panels, the types of encryption technologies identified and the encryption of information transmission.

　　Compared with the traditional mechanical door lock, its unlocking method is more intelligent and convenient, and it can realize remote unlocking, password unlocking, fingerprint identification and other unlocking methods. However, because the smart door lock involves personal privacy and security issues, it must adopt high-intensity encryption technology to ensure security. This article will introduce you to.

　　Introduction of encryption technology commonly used in front and rear panel communication of intelligent door lock.

　　01. Symmetric encryption technology

　　Symmetric encryption technology refers to encryption technology that uses the same key for encryption and decryption, also known as shared key encryption technology. In the intelligent door lock, it is a common way to adopt symmetric encryption technology. For example, when the user unlocks the lock through the remote mobile phone APP, the APP will encrypt the instruction input by the user and then send it to the smart door lock. After receiving the instruction, the door lock will decrypt it with the same key to realize the unlocking function. The advantage of symmetric encryption technology is fast encryption and decryption, but its disadvantage is that the key must be shared between the user and the door lock. If the key is leaked, the security of the door lock will be threatened. Commonly used include AES, DES, RC5 and RC6.

　　02. Asymmetric encryption technology

　　Asymmetric encryption technology refers to encryption technology that uses different keys for encryption and decryption, also known as public key encryption technology. In smart door locks, asymmetric encryption technology is mainly used for user authentication and information transmission security. For example, when the user unlocks the lock by fingerprint or password, the smart door lock will encrypt the information input by the user, encrypt it with the public key of the door lock, and then send it to the door lock, and the door lock will decrypt it with its own private key. The advantage of asymmetric encryption technology is that the key does not need to be shared and the security is higher, but its disadvantage is that the encryption and decryption speed is slow. RSA encryption is commonly used.

　　03.Hash algorithm

　　Hash algorithm is an encryption algorithm that compresses messages of any length into a fixed-length digest. In smart door locks, Hash algorithm is mainly used to prevent data tampering and verify data integrity. For example, when the smart door lock receives the instruction input by the user, it will use the Hash algorithm to process the instruction, generate a fixed-length summary information, and store the summary information with the instruction. When the smart door lock receives the instruction again, it will use the same Hash algorithm to generate a new summary information, and compare the new summary information with the previously stored summary information to verify the integrity and authenticity of the data. The advantage of Hash algorithm is that it can compress data of any length into a fixed-length summary information, which can effectively prevent data tampering, but its disadvantage is that the summary information cannot be restored to the original data, so it is not suitable for encryption and decryption.

　　04. Compare the advantages and disadvantages of the above three technologies.

　　All the encryption technologies mentioned above can be used to encrypt the communication between the front and rear panels of the smart door lock. Different encryption technologies have their own advantages and applicable scenarios, which can be selected according to the actual situation.

　　Symmetric encryption technology has the advantages of high speed and high encryption and decryption efficiency, and is suitable for scenes with large data volume and high real-time requirements, such as real-time control of door locks and data transmission. However, the key management of symmetric encryption technology is complicated, and if the key is leaked, the security of encrypted data will be threatened.

　　Asymmetric encryption technology has the advantages of simple key management and high security, and is suitable for scenes with high security requirements, such as security authentication and remote control of door locks. However, the speed of asymmetric encryption technology is slow and the efficiency of encryption and decryption is low, so it is not suitable for scenes with large amount of data and high real-time requirements.

　　The advantage of Hash algorithm is that it can compress any length of data into a fixed length of summary information, which can effectively prevent data tampering, and is suitable for data integrity verification and data tampering prevention scenarios. However, the disadvantage of Hash algorithm is that the abstract information cannot be restored to the original data, so it is not suitable for encryption and decryption.

　　05. Sum up a sentence

　　For the local communication encryption of smart door locks, we can choose the appropriate encryption technology according to the actual situation, and comprehensively consider the requirements of security, real-time, efficiency and convenience.

　　The price of smart locks has always been a hot topic, from the original being spit out to the present being gradually accepted. In fact, smart locks are constantly being updated.

Through three professional R&D teams in Italy, Hangzhou and headquarters, it has built a lock core with the strongest security performance. The anti-technology opening time of the lock core is much higher than the highest standard in the industry, and the core components inside the lock core are made of stainless steel, which greatly improves the anti-explosion opening performance.

　　The small advertisement asked the "locksmith" to install an "advanced" door lock cylinder.

　　On the evening of May 25th, Ms. Zhang, a citizen who lives in Xingbei New Town, jimei district, asked for help in unlocking service, because the key was left in the house, and Master Feng Chunbao came to provide unlocking and repairing service. Master Feng found that the door lock of Ms. Zhang’s house is not the advanced lock core she said, but an ordinary lock core with very general anti-theft performance. As a result, it took Master Feng less than one minute to unlock the big door of Ms. Zhang’s house, which surprised Ms. Zhang greatly.

　　Only then did Ms. Zhang know that it was a "black-hearted" locksmith who replaced the lock core at home before, and what she replaced was just an ordinary lock core. The normal market price was 80 to 100 yuan, and the most terrible thing was that the anti-theft performance was very poor.

　　"Black-hearted" locksmith unlocks and repairs locks, shoddy.

　　It turned out that this "black-hearted" locksmith was "summoned" by a small advertisement when Ms. Zhang forgot her key six months ago. As a result, the locksmith who came to the door always stressed that it was necessary to pry the lock to open it, and that a lock core should be replaced after the lock was pried open, and recommended the lock core with "advanced" and "good anti-theft performance" to Ms. Zhang, and accepted 360 yuan. Today, the contact number of this locksmith has not been answered.

　　The police will help you.

　　★ How to choose a lock core with good quality and anti-theft performance?

　　At present, household door locks are generally divided into three levels:

　　First, grade A, the qualification standard is that the technology has been on for more than 1 minute.

　　Second, class B, the qualification standard is that the technology has been on for more than 5 minutes.

　　Three, super B level, to be unable to open the technology or technology for more than 270 minutes as the standard.

　　Police reminder

　　★ The citizens should be cautious when asking for help in unlocking service, and do not contact the wall advertising information of unknown origin (that is, the unlocking phone in the psoriasis advertisement mentioned above).

　　★ According to the police, there are three main security risks: ① The other party is fooling people, and the more people don’t understand, the more likely they are to be overcharged, and they often take the way of destroying the lock core and replacing the lock body to meet their personal interests; ② The person who unlocked the lock was not put on record, his identity information was unknown, and there was no uniform clothing and work card for the masses to identify, so it was difficult to find it afterwards; (3) individual social locksmiths with ulterior motives are working as locksmiths today.
