【Step 1, follow me first】Hello everyone
I am a digital expert who loves to toss around!
preface
As one of the earliest users who participated in Xiaomi's crowdfunding to get fingerprint locks, it has been more than 5 years now, and it can be said that I am a witness who witnessed the early development process of fingerprint recognition smart door locks.
Posting a Luke smart fingerprint lock Classic that participated in Xiaomi's crowdfunding order cost ¥1699 yuan, which can be regarded as opening the era of "semi-smart" smart door locks. It may also be that the early Luke smart door lock quality control is not good, less than a year fingerprint lock a small area of paint off, two years later is already a large area of paint loss. And Luke's fingerprint recognition often has a decline in fingerprint recognition rate, which was originally purchased for the FPC semiconductor fingerprint recognition module, and it really feels not as high as the fingerprint recognition rate of the optical (green-emitted) fingerprint recognition smart door lock of the times. Although the fingerprint lock of this deer is still in service, the house he lives in has also been rented.
Xiaomi smart door lock face recognition X purchase channel and starting price
Because I was preparing to replace the mechanical door lock of the old and dilapidated community where my parents lived, I directly placed an order for Xiaomi smart door lock face recognition X on JD.com. I used a combination of coupons and Jingdou and Jingdong gift cards to pay, and finally paid ¥2369 yuan.
Mechanical key lock display for security door in old dilapidated neighborhood of parents
Speaking of this house in the Shenzhen area is also almost 30 years old, in the early years, my parents came down from Hubei to Shenzhen to work hard with the tide of reform and opening up in Shenzhen, my father was engaged in construction units (China Construction Third Bureau), after all, my father who is a national first-class builder has also led the construction of Shenzhen International Trade Building, Shenzhen Diwang Building and other landmark buildings. This house is considered to be the original unit distribution house, but it was transferred to an individual in the early 2000s. This complex is an old staircase, and it is a four-family structure layout. You can see that the door of the neighborhood is still the same as it was back then, and now I have recovered my childhood memories in terms of returning.
My parents' house went through two renovations, the first in the early 90s, and the second in 2016, when the security door was still the kind of mechanical lock with a heaven and earth hook.
Why did I decide to eliminate the mechanical lock of my parents' house and replace it with Xiaomi smart door lock face recognition X, it is because there have been many cases where my parents forgot to bring the key home from a business trip or went home after traveling abroad to find that the key was lost, and each trip to find a lock master would cost about two or three hundred. Taking advantage of this time I returned to Shenzhen from Huizhou to deal with some things, stayed at my parents' house for a while, in order to avoid forgetting to bring the key and stand at the door, I thought about it and decided to change the lock.
Xiaomi smart door lock face recognition X unboxing display
Because at that time, when I placed the order, it was sent to Huizhou, thinking that if I canceled the order, I was worried that the coupon would be invalidated, so after receiving Jingdong Express in Huizhou, I switched to SF Express to send it back to my parents' house in Shenzhen, and in the future, I must look at the address before placing an order on Jingdong and then submit the order, although the courier fee is not high, there is actually no need to spend this fee.
Why would you choose Xiaomi smart door lock face recognition X, is for these four points. For me, a smart door lock must meet my needs in terms of appearance, and the material is also exquisite. Xiaomi smart door lock face recognition X is with a round AMOLED screen, and only X is the front and rear panels are tempered glass material, compared to the IML (in-mold insert injection) process of hard transparent plastic base tempered glass texture and scratch resistance is definitely the best. And the automatic lock body is also what I value, after all, my parents often habitually go out and go downstairs to worry that the door lock at home is not locked and have to climb the stairs to the 5th floor to check whether the lock is closed, and now with the automatic lock body, there is no need to do more. The old shabby community previously installed an electronic doorbell at the door, and after a few years of use, I found that I don't know if it is bad contact or where it is broken, if the family does not hear the doorbell, every time the takeaway brother presses the doorbell and no one opens the door, he will directly throw it on the ground and go, now Xiaomi smart door lock face recognition X has an integrated electronic doorbell, this function I must like.
Xiaomi smart door lock face recognition X product model: XMZNMS06LM, product size: 411.0 mm × 77mm × 20 mm (front panel), 411.0 mm × 77mm × 26.3 mm (back panel), product net weight: 6.5kg, power supply mode: 6250mAh lithium battery (7.6V-2A), Type-C emergency power supply (5V-2A), wireless connection: Bluetooth 5.0, Wi-Fi 4 (2.4GHz, 802.11n), NFC, lock cylinder security level: Class C.
At that time, after the delivery of JD.com, I arranged for SF Express to be sent to Shenzhen, so the unpacking inspection was also done at my parents' house. Here is an installation cut-out diagram, don't throw it away to the master who installed the door lock, I forgot to put it back after unpacking and inspection, my mother put it away when she cleaned, fortunately it was not thrown away as garbage by my mother, otherwise it would be troublesome.
I have to say that the weight of this set of Xiaomi smart door lock face recognition X is still a little heavy, all wrapped in plastic bags, I am light to take and release for fear that one did not hold it firmly and fell on the ground, hahaha.
Since it is the first time to use Xiaomi smart door lock face recognition X, the instruction manual must be read, otherwise you don't know how to reset it in the future.
And in the instruction manual of the product there is a reset needle, this is actually the same as the SIM card needle of the mobile phone, don't put it indiscriminately, reset Xiaomi smart door lock face recognition X will be used.
Xiaomi smart door lock face recognition X parts display
To be honest, this is the first time I use the lock body of a fully automatic door lock, and it seems that there should be a motor inside the structure.
Sure enough, there is a data cable from the lock body of this automatic door lock, and the unpacking inspection only needs to check whether this data cable is broken.
Xiaomi smart door lock face recognition X built-in two large-capacity lithium batteries, rated capacity: 6250mAh, nominal voltage: 7.6V, energy: 47.5Wh, rated charging input: 5V-2A (Type-C), charging limit voltage: 8.7V. It should be noted that there is a Type-C interface under the metal contact of the lithium battery, and you can directly plug the Type-C charging cable of the mobile phone into the charge.
Xiaomi smart door lock face recognition X lock cylinder and key are sealed in a plastic bag, if it is damaged, you must pay attention. When I opened the box and inspected the goods, I found a small defect (I don't know if it was), that is, there was a small defect in the lock cylinder. Each set of Xiaomi smart door lock face recognition X comes standard with two keys, and the master who installed the door suggested that my parents take a set of keys, and I take a set of keys for backup.
Xiaomi's key workmanship is quite good, and I have already processed the key pattern in the picture.
There is also a package of plastic bags wrapped with a bunch of screws, screws and other accessories for installing door locks, pay attention not to put them randomly after opening the box and inspecting the goods, this should be left for the master who installs the door lock, in case it is lost, it will be very troublesome.
This is the back panel of Xiaomi smart door lock face recognition X, the lock body is made of aluminum alloy, the base material of the cover plate is tempered glass, and the inner layer of the lock body near the door is a thick rubber material. There is a protective film on the door lock, and remember to tear it off after installing the door lock to use it.
The tempered glass of this back panel is actually covered with a layer of aluminum alloy plate, and the battery compartment cover is opened through this button on the top cover of the back panel.
The switch and reset hole of the door lock are all in the battery compartment, and if you carefully read the instruction manual, you should be able to figure out how to operate.
The core component of Xiaomi smart door lock face recognition X is this 3D structured light face recognition module, and this technical principle is simply understood as the iPhone Face ID module. At present, 3D face unlocking is mainly two genres: 3D structured light and 3D TOF, Xiaomi and Aqara (green rice) are using 3D structured light solutions (high cost), other smart door lock brands (including Huawei) are using 3D TOF, most smart door lock brands use SenseTime's 3D TOF solution (low cost).
3D TOF stands for 3D Time of Fight, which literally translates to 3D stereoscopic time-of-flight. At present, the smart door lock manufacturers using this 3D TOF camera technology are mainly Huawei and 3D TOF camera integrator: SenseTime. This is a face recognition method based on time difference ranging. It will continuously emit a light source to the object, when it encounters the object and reflects back, it calculates the time when the light source is emitted to the reflection back, analyzes the different reflection times, and combines the camera to form a 3D stereo model. The advantage of TOF is that the algorithm requirements are low and the unlocking speed is fast. However, the imaging resolution of 3DTOF is not as good as 3D structured light, and when it comes to face recognition, it is obvious that the accuracy and safety of 3D structured light will be higher.
Xiaomi smart door lock face recognition X is also with a password button area, which supports unlocking by password.
Of course, the most important emergency key chain (door lock key) unlocking method is also the last unlocking method of smart door locks.
Xiaomi smart door lock face recognition X also supports fingerprint recognition unlocking, and the fingerprint recognition module is inside the door handle.
The connection line of Xiaomi smart door lock face recognition X is made of this metal terminal head, which is obviously more reliable and stronger than the plastic buckle of some domestic cottage cheap brands.
This is the rear handle on the back panel, you can see that Xiaomi smart door lock face recognition X uses thickened all-aluminum profiles, which is really cost to Xiaomi compared to other brands in terms of materials.
Since a fully automatic lock body is used, there is a door opening button on the rear handle on this rear panel. After the experience, my parents are very satisfied, the operation is simple and easy to use. This is the real technology to change life, directly and greatly improve the user's perception of the use of smart door locks, in other words, I use it cool, use comfortable.
Of course, Xiaomi smart door lock face recognition X also has a child lock function, and there is also an emergency door opening knob. Compared with many other brands of smart door locks, one more structure and module will greatly increase the cost of mold opening, and will also increase the cost of the product. But Xiaomi smart door lock face recognition X is completely unambiguous in this regard, and friends who fancy child locks and emergency door opening knobs must not miss it.
Xiaomi smart door lock face recognition X master door-to-door installation process
The phone has made an appointment in advance for the Xiaomi smart door lock installation master to arrange the door, and the master's kit has a reinforced metal bar with an anti-theft door.
Because it involves removing the original door lock, the master will let the user sign an agreement to transform the door lock, after all, it is irreversible that the hole of the door needs to be grooved, so this can still be understood.
Even the chainsaw was used, and sure enough, the installation master's tools were really complete.
Finally, after cutting holes, digging grooves, grinding edges and other operations, it was finally possible to install Xiaomi smart door lock face recognition X.
Xiaomi smart door lock face recognition X after installation of the finished product display
There are no more than 5 smart door locks installed in my parents' old and dilapidated community, of which this set of Xiaomi smart door locks face recognition X in my parents' house should be regarded as the best appearance and unlocking experience in the existing smart door locks.
For my parents, this set of Xiaomi smart door lock face recognition X smart door lock they all recognize, that is a great improvement of their home unlock experience.
Whether the smart door lock is a lithium battery or a dry battery is better, see my comparative feedback
The house I have taken to rent is the Luke Classic fingerprint lock, which needs to install 8 No. 5 dry batteries, and it must be a special battery for smart door locks, and the batteries bought on the market such as Nanfu concentrated energy ring, 555, Duracell have been tested and replaced without response, consult Luke customer service to recommend buying a special smart door lock dry battery. I stepped on this pit, and simply bought the Shuanglu No. 5 dry battery for smart door locks on Jingdong, avoiding the embarrassing situation that the dry batteries bought in offline convenience stores and supermarkets could not be used.
Here I have consulted a friend around me to start Xiaomi smart door lock face recognition (F1), his model is relatively simple compared to X, the core is the power supply method from Xiaomi smart door lock face recognition X lithium battery replaced by 10 No. 5 dry batteries.
Xiaomi gave a statement of 6 months of battery life, in fact, my friend said that it is about 4 months to be replaced, just take the Shuanglu smart door lock No. 5 dry battery I often buy, buy 40 pieces can probably meet the needs of a year, the cost of a year's battery (including freight) is close to 100 yuan.
The Xiaomi smart door lock face recognition X is powered by lithium batteries, and two lithium batteries are equipped as standard. Xiaomi gave a statement of 6 months of battery life, according to my usage perception this month, after full charge, in the case of multiple times a day and trigger door video recording is more frequent, it is estimated that it will take almost two months to charge.
The 3D structured light face recognition unlock of Xiaomi smart door lock face recognition X is measured
Basically, as long as the user who has been authorized by face recognition, it can automatically start when Xiaomi smart door lock face recognition X detects the user. Simply comparing the Huawei 3D TOF face unlocking experience experienced in Huawei stores, the unlocking speed of Xiaomi smart door lock face recognition X will be faster. And in the process of entering face recognition, Xiaomi smart door lock face recognition X can display the recording process on the circular AMOLED screen, Huawei can only operate the recording process through the smart life APP, and the intuitive use experience is still better than Xiaomi smart door lock face recognition X.
The fingerprint unlock of Xiaomi smart door lock face recognition X is measured, compared with the gap in fingerprint recognition rate and unlocking speed of Luke fingerprint lock before
The fingerprint recognition success rate of Xiaomi smart door lock face recognition X is very high, and the lock can be opened when the fingers are sweaty. Compared with the Luke Classic fingerprint lock, the fingerprint recognition success rate is obviously low, then I must complain that fingerprint recognition is often unsuccessful and leads to a penalty station at the door. Considering that this comparison is biased, after all, Luke Classic is an early fingerprint recognition smart lock in 2017, then compared to the last time I went to the company's colleague's house, he installed the TP-LINK fingerprint lock also encountered the failure of finger sweating fingerprint unlocking, to know that in 2023 the thousand yuan price FPC semiconductor fingerprint recognition module will still exist in this situation, Xiaomi smart door lock face recognition X obviously in fingerprint recognition even if there is sweat in the case of unlocking success is still very high.
Mijia APP use
In order to match the use of Xiaomi smart door lock face recognition X, I brought the Redmi Xiaoai speaker Play sent by the Xiaomi sweeping robot I bought before, and the Bluetooth MESH gateway can be enabled in the actual test. Of course, I recommend getting a small love speaker with a screen to match it together, which can be used as a monitoring screen for smart door lock cameras to view or play back videos.
At present, Xiaomi Smart Door Lock Face Recognition X supports administrators (one, supports all unlocking methods/anti-locking/door lock local settings), multiple ordinary users (all unlocking methods) and frequent visitor users (only supports periodic password unlocking).
Xiaomi smart door lock face recognition X is a process that supports viewing and recording faces through a circular AMOLED screen, and the process of recording fingerprint recognition can also be viewed through the APP, and also supports setting a password on the APP to unlock the lock.
Xiaomi smart door lock face recognition X also supports Xiaomi, Redmi's smart phones (need to support NFC function), smart bracelets, smart watches, NFC cards to use NFC unlock function, because family phones do not support NFC function can not experience NFC unlocking.
Enter and view the Xiaomi smart door lock face recognition X in the Mijia APP will show the situation of opening the door today, and whether to open the child lock and anti-lock can be viewed on the APP.
Xiaomi smart door lock face recognition X can also generate a one-time password for unlocking.
I have set up the family's unlocking method, because my dad often runs to the construction site and his fingers are easy to dust and he does not record fingerprint unlocking, and when I go home, I can enable password unlocking.
Xiaomi Smart Door Lock Face Recognition X's setting interface.
Local door lock settings, child lock settings are available, and the anti-lock function can also be turned on on the APP.
Manual arming, camera settings and linkage settings, generally I am used to viewing on the APP, so I did not buy a small love speaker with a screen to use. If you need real-time viewing and playback for camera recording, it is recommended to purchase a small love speaker with a screen for linkage.
Face unlock is really convenient to use.
It is recommended that the default settings do not change, and the sound settings are best not moved to keep the default.
The APP must enable notification management, and it is recommended that the emergency phone number should also be filled in.
It is also very simple to follow the illustration, it is quite convenient to replace the battery, you can also check the remaining power of the battery, and you can also open a key to save power in the APP.
In the APP, you can also check the networking status of Xiaomi smart door lock face recognition X.
Here I have made a simple smart scene, the implementation process is also very simple, just need to match a Redmi Xiaoai speaker Play. The scene is like this, when going home through Xiaomi smart door lock face recognition X unlock, Redmi Xiaoai speaker Play will trigger the scene of going home, through the linkage to play voice prompts: hard work, welcome home! My mother also felt awkward at first, but when she got used to it, she felt that it was still humane. This is how technology changes life, and it integrates human touch into technology products.
Xiaomi Smart Door Lock Face Recognition X can record three days of free rolling video storage service (cloud storage), and supports viewing 3 days of rolling video on the APP. Of course, if there is a small love speaker with a screen, it can be played back and viewed on the screen.
Of course, after turning on the rolling video of video recording, the battery of Xiaomi smart door lock face recognition X will consume a lot, and this function will consume a lot of power.
Xiaomi smart door lock face recognition X also supports online networking OTA to upgrade the firmware.
In the end, what is the difference between the measured Xiaomi smart door lock face recognition X and the measured Xiaomi smart door lock face recognition (F1).
Compared with the smaller Mi smart door lock face recognition X lacks NFC door card, Xiaomi mobile phone, Xiaomi watch, Mi bracelet, Siri voice unlocking (HomeKit) support in the unlocking method. [In a simple word, there is no NFC module and related functions].
Xiaomi smart door lock face recognition (F1) compared with the smaller Mi smart door lock face recognition X lacks a camera (90° monitoring angle, 720P clear picture quality) does not support video recording, and there is no camera battery life. [In a simple word, there is no camera module and related functions].
Xiaomi smart door lock face recognition (F1) compared to the smaller Mi smart door lock face recognition X does not need to be paired with a Bluetooth gateway. [In a simple word, you don't need to buy a Bluetooth gateway that supports Bluetooth MESH].
Compared with Xiaomi smart door lock face recognition (F1), Xiaomi smart door lock face recognition X only supports Mijia (Xiaomi smart ecology) linkage. [In a simple sentence, Apple HomeKit cannot be linked].
Xiaomi smart door lock face recognition (F1) compared to the smaller meter smart door lock face recognition X only uses IML (in-mold insert injection) process, hard transparent plastic substrate. [In a simple sentence, not tempered glass substrate].
Xiaomi smart door lock face recognition (F1) has more advantages in price than the smaller meter smart door lock face recognition X, Xiaomi smart door lock face recognition (F1) only ¥2199 yuan, Xiaomi smart door lock face recognition X needs ¥3299 yuan.
summary
In the current 3D face lock, Xiaomi's advantages are obvious, and Xiaomi smart door lock face recognition (F1), Xiaomi smart door lock face recognition X in the current 3D face lock on brand, product workmanship and quality control, after-sales and other aspects are more guaranteed. On the whole, the core advantages of Xiaomi smart door lock face recognition (F1) and Xiaomi smart door lock face recognition X are [3D structured light] and [independent NPU], relying on the improvement and optimization of algorithms, it has become the most technical 3D structured light head brand in the 3D face lock industry. At present, in the two gradient prices of 2,000 yuan and 3,000 yuan, it can be said that no one can beat the right. Of course, Xiaomi as a low-price market competitor set off a catfish effect is still very terrifying, to say that Xiaomi mobile phone dry up the cottage machine market, then Xiaomi can be called the leader of the smart door lock market.
