My wife, who never uses fingerprints to unlock a lock, made a big move this time.

People nowadays have a strong ability to accept new things. With the maturity of technology, the once-questioned fingerprint lock has been recognized by most people and entered thousands of households. After all, safety has been guaranteed, and it is indeed what people want to live conveniently.

As a digital enthusiast, I have a strong desire to explore new things, and I changed a lot of fingerprint locks at home early. The reason for repeated replacement is not the quality problem. But because my wife's fingerprint is shallow, no matter whether she can input it at that time, as long as it's time to unlock it, she can't open it. Forced to be helpless, I can only unlock it with a password. Although it is convenient to enter the password, I have seen many movies and have many terrible ideas. For example, will someone peek at the password? Can you identify the password with white powder?

Although there are various ideas, I have basically given up the idea of replacing the fingerprint lock because of my busy work. However, my wife has been reluctant. This time, start with _ Luke finger vein automatic door lock sv40 directly.

All the previous contacts were fingerprint locks, which were unlocked by fingerprint images. The finger vein lock chosen by my wife this time relies on the vein image under the interphalangeal cortex to unlock it, and it is also a roundabout tactic for people with shallow fingerprints and easy peeling. Moreover, this fingerprint lock uses deeper biological information, which is basically impossible to copy and more secure.

As one of the ecological chains of Xiaomi, Luke has long been known to the public. I have been doing things silently with solid quality. This service is more in place than the Luke fingerprint lock purchased before. After placing the order, the after-sales personnel immediately make an appointment for installation. This positive attitude is quite pleasing.

Small package, the accessories are quite complete after opening, which shows that it is small. If it is a standard door, there are enough accessories here. Even the guide vanes that needed to be measured at the beginning were equipped together.

The color scheme of the door lock is black and metallic gray. It looks very textured The overall shape is not abrupt, giving people a sense of calm and atmosphere.

The big Luke Logo on the outer panel of the car door is similar to the current ins wind, which is particularly beautiful.

The operation area of the outer door panel includes password panel area, NFC area and doorbell button, all of which are touch buttons, which are simple and elegant.

The interior of the exterior door handle refers to the vein recognition area. It is also the core security advantage-refers to vein recognition. Not easy to copy, not easy to steal, high recognition rate and high stability. Fingers need to touch the concave and convex areas on both sides of the recognition area for recognition operation.

There are dual speakers and Type-c charging port under the outer door lock panel. The volume of the dual speakers is so loud that 100 square meter room can be clearly heard when reminding and doorbell operation are carried out. The emergency power supply port is that the door lock is dead, and the charging treasure is used for emergency unlocking. The common Type-c lines and charging treasures on the market are basically prepared for travel, so there is basically no need to worry about the problem of no electricity. Of course, mechanical unlocking is also very convenient.

According to this cardboard, the opening position of all parts can be measured and located. But the first installation is free, basically no one needs to do it, and the installation master basically doesn't need this.

The lock body is made of good material, which makes people very trustworthy from the sense. With the C-class lock core, I am very relieved to give my home to Luke's finger pulse SV40.

Due to the different thickness of the actual door panel, the self-contained narrow guide vane is not universal. After the initial measurement, a guide matched with the door panel will be installed.

The lock core is a C-class lock core with high safety level on the market, which is very safe. Even if the panel is completely destroyed, you can't make a fuss about the lock core.

The steel plate of the lock core is quite thick. Without the cooperation of mechanical keys, it is impossible to open the door easily. If the machine still adopts the folded shape of fingerprint lock, the LOOCK mark on it will be easy to distinguish. Mechanical keys are mostly used in emergencies. Usually I put one in the car and one in my relatives' house, but I have never used it.

The materials and workmanship of accessories are excellent choices. As small as every screw, the structure is quite exquisite, with no rough marks.

The screws are also made of steel. From the smallest thing to see the essence and the attitude of the merchants, I think everyone should know.

The quality of double deer brand can always be comparable to that of Fu Nan. The 8 batteries equipped with the Shuanglu electronic lock will be more durable, and the Luke door lock has always been more energy-saving, and it is basically not a problem to use it for 9 months.

After the appearance, talk about installation. The first installation is free, and the installation master is conscientious and very strict. The master in overalls and gloves is my first time to install four locks. Because it is the first time to install, the installer will install it after the power-on test and the function is normal.

My home is a standard door, which will not be damaged basically, and simple repair will not affect the replacement of other door locks.

Install two side panels, which is very simple. To tell the truth, I could have installed it myself if it wasn't free.

Strict installers compare the positions of door locks, so that the door lock panel will not be tilted and affect the appearance after installation. This is my obsessive-compulsive disorder.

Power-on settings and test whether each function is in good condition, so as to prevent accidental closing of doors and failure to open doors.

The door lock was installed successfully. Isn't it beautiful?

After installing it, the first thing to do is to let my wife try it. After all, it is so that she can unlock the lock with her fingers. After input, after repeated attempts, the wife's finger vein recognition rate is 100%. This can make my wife happy, and finally I don't have to press the password all day like an alien.

Trying to unlock the password, sensitive to touch, normal function. And the panel will not leave fingerprints easily, which is very good.

The sound of the doorbell can be said to be huge, but fortunately, the sound size of the doorbell can be set in the Mijia APP.

The lock of the mechanical key is quite smooth, which made me once suspect that one of the benefits I used was fake.

Indoor door lock panel is simple and generous. Three simple unlocking methods are also concentrated in the same area, which is very easy to operate.

The operation is simple, just touch the concave-convex area of indoor door lock panel with your finger and press the key to unlock it.

The small button at the bottom is used to unlock the lock. The upper knob can also be used to unlock the operation.

Let's talk about the APP. As a member of Xiaomi's ecological chain, Luke's fingerprint lock needs to be connected to the "Mijia" APP. Mijia APP is now very mature, and you can find the device you need to connect in classification or search.

When the device is connected, a post can be set to perform a series of operations on the door lock. Such as door lock settings, doorbell settings, etc. You can also access smart scenes, which is quite powerful. The interface of Luke vein lock is also super intuitive for the dynamic display of door lock. Set up multiple finger veins, and the password can be easily managed.

Whether you are at home or not, you can easily understand the access situation at home after accessing Mijia APP.

Although this door lock was bought by my wife, I still feel very fulfilled. After all, this fully automatic lock SV40 has a high value, and it is super textured when installed on the door. Moreover, the finger vein unlocking method has a high recognition rate, and the security method that is difficult to copy and steal also ensures the property safety to the greatest extent. The abnormal door lock will also be remotely warned by Mijia APP, which is really a pretty good smart lock. The most important thing is that my wife is very satisfied. It is safer to lock with a password than to be an alien.

Although technically speaking, this fully automatic lock SV40 for Luke's finger vein is already very high, and the price is slightly higher than that of SV30 pro. I hope to reduce the price later.
