With the popularity of smart homes, more and more household articles have joined the ranks of smart devices, from smart TVs, smart refrigerators and other household appliances to smart toilets, intelligent curtain and other non-household appliances, all of which have intelligent functions. The emergence of smart door locks was news more than ten years ago, but then there were news of illegal cracking, black boxes and so on, which discouraged the majority of users who dared to adopt early adopters. With the continuous development of the smart industry and the improvement of biometric technologies such as fingerprints and NFC, the security of smart door locks has also been greatly improved. Today, I will introduce you to a fully automatic intelligent door lock of Xiaomi, which is different from the previous intelligent door lock. This door of Xiaomi has not only greatly improved its safety performance, but also can be opened without pressing the door handle after the user successfully recognizes it, which is more convenient. Let’s take a look.
Appearance and function
The first impression when I received the door lock was that the box was too big and heavy. However, after unpacking, I found that a model door was attached to the original box for installation and testing. The lock tongue of the model door was made of transparent material, which was more convenient for users to observe the automatic door locking. The package of the door lock itself is also rectangular, and it is full of weight in your hand, nearly 4.6 kilograms.
Open the door lock packing box, and there are three independently packaged boxes, namely, the inner and outer handles of the smart lock, the lock body and accessories, and there is also a cardboard card template for opening the door.
Generally speaking, Xiaomi’s fully-automatic intelligent door lock is very fine in manufacturing process and solid in materials. The weight of a single lock body is 1.2 kg, which is difficult for the lock body of a general anti-theft lock to achieve. The lock body is of Class B safety level, and it is designed with a straight plug. The lock tongue is a combination of detection tongue+scissors tongue+anti-lock tongue, and it does not support the hook of heaven and earth. However, if the security door has a hook of heaven and earth, it will not affect the normal use.
The door handle has an inner part and an outer part, the handle base shell panel is made of piano black, and the inner and outer handles are made of electrophoretic spraying technology, which is not easy to paint off and is more resistant to dirt.
Xiaomi fully-automatic intelligent door lock does not adopt the conventional door lock design, and the conventional anti-theft lock needs to open the door by pressing or pulling the handle, but the Xiaomi fully-automatic intelligent door lock does not need to press the handle, which is more convenient to use, more modern to foreign businessmen, occupies a smaller area of the door panel, and looks less formal to users with small door panels, and is more beautiful than ordinary door handles.
Let’s look at the external handle of the door lock. The upper part is the control area, which includes the doorbell button, password input area, lock indicator light and NFC identification area. These areas are all black in standby state and have a strong sense of integrity. Only after touching will the keys in the password area be displayed.
There is an emergency unlocking hole under the NFC identification area. When the battery of the smart door lock runs out of power or fails, you can use the emergency key to insert and rotate the lock. Xiaomi’s smart lock is equipped with a C-class security lock core, which can effectively prevent criminals from cracking it.
Below the emergency lock hole is the door handle, which is made of frosted material and feels good. The fingerprint sensor is located above the handle, which is ergonomic. When pulling the door handle, the thumb will naturally be placed in the recognition area, and the door will be opened immediately after the recognition is successful, without pressing or pulling.
When using fingerprint to unlock, the key area finger will not light up. There is a long indicator light at the top of the handle bottom shell panel, which will light up white after receiving the correct unlocking instruction, and will light up red after receiving the wrong unlocking instruction, clearly showing the unlocking status, which is convenient for users to perceive whether the unlocking is successful or not.
Xiaomi automatic intelligent door lock adopts a new generation of multi-dimensional fingerprint identification technology, which combines multi-dimensional information such as fingerprint, skin and conductivity to realize multi-dimensional fingerprint identification, with higher security, faster door opening speed and recognition rate as high as 98.84%.
There is also a USB-C charging port at the bottom of the panel, which can be charged by the mobile power supply when the battery of the door lock is dead. However, you don’t need to worry too much. Xiaomi is thoughtful about low battery reminder. It is very convenient to have obvious tips on both the door lock and the Mijia APP.
Next, look at the inner handle. The bottom shell and panel of the inner handle are the same as those of the outer handle. There is a button at the position of the fingerprint sensor of the door handle, and the door can be opened by pressing this physical button. There is an anti-lock button below the door handle, which can be locked by pressing it for 1.5 seconds every day, and can be cancelled by pressing it again. If the pressing time is insufficient, the anti-lock state will remain unchanged. This design can effectively prevent children from accidentally touching the anti-lock button.
There is an emergency unlocking knob above the inside of the handle, which is convenient for unlocking when the door can’t be opened indoors. There is also an unlocking status indicator above the knob, which is different from the long indicator outside the door. Inside the door is a small lock sign, which lights white when the door lock is normally opened and red when it is unlocked incorrectly.
installation and trial run
The inside and outside handles of Xiaomi’s automatic door lock are introduced above. Next, we will call the master to install the door. You can scan the code for installation, or you can make an appointment through WeChat WeChat official account or call 4001005678 customer service. The installation master is very professional. After determining the installation time, he will first check the original door lock, and after removing the old lock, he will transform the security door according to the situation. The whole installation process is very rapid.
It is commendable that this millet is not equipped with mounting screws of various sizes, but only equipped with a set of screws at each position. The screws are designed in sections. When installing, the master will cut the screws according to the size of the door to avoid waste. The connecting rod of the lock core is also in this way. It can be installed after being cut according to the thickness of the door, and then the battery can be installed and turned on.
Two gaps can be seen on both sides of the joint between the handle of the inner side door and the bottom shell, which can be buckled with two hands. After opening, you can see the battery compartment, which needs 8 batteries for power supply. In fact, the battery compartment is divided into an upper part and a lower part. Only four batteries are needed to supply power to the door lock, and the two batteries are more secure. If one battery is placed without electricity, the door cannot be opened.
Two physical buttons can be seen below the battery compartment, namely the setting key and the reset key. The setting key is mainly used to connect with the mobile phone through Bluetooth when the user uses the door lock for the first time, and the reset key is used to restore all settings to the factory state.
If Xiaomi eco-chain equipment has not been used in the early stage, and Mijia APP has not been installed on the mobile phone, you need to scan the QR code on the inner handle sticker for installation first. When you open Mijia APP, a pairing prompt will appear. Press the Set button according to the prompt to start pairing.
Smart door locks can be found by scanning nearby devices in Mijia APP, or in the list of new products or home security devices. The first step is to set the administrator password and fingerprint. It should be noted that this administrator password has high authority, which can not only add other users, but also use password, fingerprint or NFC to unlock the house when it is locked. Later, you can add fingerprints and passwords of other family members, and each fingerprint needs to be entered 10 times in total, which is convenient for rapid identification from various angles.
The last step is the door lock acceptance, a total of nine steps, in fact, is to use all the functions of Xiaomi automatic smart lock to see if there is any problem in installation. If the lock is not smooth, the installer can directly adjust it to the best state.
Functional highlights
The biggest feature of Xiaomi’s fully automatic intelligent door lock is full automation. The so-called full automation means that you don’t need to press or pull the door handle, and you can open the door after successful identification. Xiaomi also has a detailed explanation of fully automatic, semi-automatic and manual door opening in the product page. Simply put, this lock combines the two steps of identification and unlocking into one step, which is simpler. When the door is closed, when the sensing tongue retracts, the locking tongue will automatically pop up.
Xiaomi’s fully automatic intelligent door lock has a built-in linear power drive system, an innovative linear power system composed of planetary gear deceleration, micro-motor power, state sensing and other components, and a small current linearly drives the lock tongue, which makes the automatic expansion and contraction of the lock tongue more stable, faster and quieter. It only takes 0.8 seconds to automatically lock the door. Once the system detects that the door is not closed properly, it can also give an audible prompt.
This supported 7-in-1 unlocking mode can be unlocked by using temporary password, emergency key, Mijia APP, NFC device and HomeKit in addition to conventional fingerprints, passwords and emergency keys. I believe that many users will take fingerprint unlocking as their first choice, which is convenient and practical, and the security is also very high. However, if you are a younger user, you may not be able to unlock the lock because the fingerprint is too shallow or the fingerprint changes. You can choose other ways here. It is not recommended to use the password to unlock the lock frequently here, because the password is very easy to leak, and once it is known by outsiders, it is no longer safe.
If the fingerprint is entered incorrectly for 5 consecutive times, the system will be locked for 5 minutes. Users may often encounter the situation that their hands are dirty or the fingerprint recording hand is carrying something and needs to be unlocked. This can be solved by entering multiple fingers of the left and right hands, or by opening the door through a mobile phone or password. The password can be set in virtual digits, and only 6-10 digits are needed for actual unlocking, which can be set according to the use environment for users with security requirements.
NFC unlocking is also very convenient and safe. Xiaomi’s smart lock supports Xiaomi mobile phone MIX.
2S, Xiaomi 10/10Pro/10 Youth Edition, Xiaomi CC9, Xiaomi 9, Xiaomi 6, Redmi K30/K30Pro; Mi band 3/4/5NFC version; Xiaomi Watch and Xiaomi Watch Color have a wide range of applications.
The Bluetooth unlocking procedure of the mobile phone is a little cumbersome. You need to unlock the mobile phone first, open the Mijia APP, find the smart door lock and wait for the connection before you can unlock it. This method is best used as a backup unlocking method. The principle of HomeKit unlocking is similar to that of Bluetooth unlocking, but the function of unlocking by Siri voice is added.
Temporary password unlocking is mainly used for relatives and friends to enter the home when the owner is inconvenient to open the door. Most smart door locks in the market have this function, which can randomly generate temporary passwords or periodic passwords for temporary use and avoid guests waiting outside the door.
Spare key unlocking is generally not used. Please remember to check whether the key unlocking is smooth after installation. If it is not smooth, please ask the installer to adjust it in time. It’s best not to put the spare key in the house. You can put it in the car, storage room or other safer places for temporary use when you can’t unlock it.
The operation of the indoor part is also very humanized, and the handle adopts double induction technology, which can effectively prevent the cat’s eye from unlocking. A finger must touch the sensing area behind the handle, and then press the door opening button at the same time to open the door. This method can not only open the door through the cat’s eye, but also prevent children from accidentally touching the door opening button to unlock it. Just like opening the door from the outside, opening the door from indoors also omits the step of pressing to unlock.
High security
Xiaomi’s automatic smart lock also supports the anti-theft alarm function. A sensor is set inside the handle outside the door. Once the handle outside the door is damaged, the speakers inside and outside the door lock will give an alarm, and the mobile APP will be reminded accordingly. If you have a Bluetooth gateway at home, you can also call the reserved mobile phone number to send a notice.
The coercion fingerprint function is also very useful. If someone threatens the user to open the door, he can use the coercion fingerprint entered in advance to open the door. After the door lock is normally opened, the system will give an alarm through the Bluetooth gateway, further improving the security of the door lock.
Xiaomi’s fully-automatic smart door lock not only has 10 security protection functions such as threatening fingerprint alarm, resisting black box attack and abnormal alarm, but also supports one-click protection from home. For users who often travel abroad, the protection mode can be turned on with one button. If there are other smart devices such as cameras and gas stoves at home, Xiaomi’s fully-automatic smart door lock can also be linked to wake up the camera for monitoring and turn off household APPliances. In case of abnormal situation, in addition to the local door lock, the mobile app will also receive an alarm.
Make home smarter.
Intelligent linkage is also the highlight function of Xiaomi’s fully automatic intelligent door lock. With the popularity of smart homes, this function is still being gradually improved. Through the linkage of various devices, the home is more intelligent. Setting instructions can push information to the mobile phone, start security equipment or start intelligent linkage equipment. For example, you can turn on the dormant camera when someone rings the doorbell or unlocks the door, you can also turn on the light at the moment of opening the door, start the sweeping robot after locking the door, and even let Xiaoai students play the welcome voice after opening the door. More interesting functions will be developed later.
summary
Generally speaking, Xiaomi’s new fully automatic smart door lock is an excellent smart home product. Its reliable safety, humanized design, fine workmanship, rich functions and beautiful appearance can all gain a leading position in the smart lock industry. "Automatic" as the main highlight of this lock simplifies the steps of opening and closing the door, and the safety and convenience are greatly improved. Seven unlocking methods completely eliminate the trouble of forgetting to bring the key, and the intelligent linkage function also brings more interesting new gameplay. It is worth mentioning that Xiaomi’s fully automatic smart door lock is also compatible with HomeKit, and Siri’s voice unlocking is even more cool, and Apple users can also enjoy cost-effective door locks.
