In recent years, the application of mobile phone fingerprint identification has become more and more extensive, which can be said to be the standard of smart phones. This quick and convenient unlocking will soon be applied to other devices, such as notebooks and smart locks to be experienced today.
In fact, it is no longer a new product to talk about smart locks nowadays. It is true that laziness is the source of technological development. Adhering to the principle of moving your mouth, don’t do it. Today, I found such a product, which can unlock the door without moving your mouth or even moving your mouth.
Face-brushing unlocking is actually a face recognition technology. From fingerprint unlocking to face recognition, this is a technological innovation, and Deshiman intelligent lock is also from Q5 to R5 before to R7 now, which is a technological progress and a trend of the times. Today, I am fortunate to be able to experience Deschman’s latest second-generation fingerprint lock R7.
Judging from the outer packaging, there is no design that Deshmanzhi can lock R7, but the words that Deshmanzhi can lock are written. And the LOGO of the product, but the functional characteristics of the product are clearly stated.
Open the package and arrange the product accessories neatly, and each accessory has a foam fixing slot, and the small accessories are also sealed with plastic bags. After reading the previous products, there is not much difference in the outer packaging of Deschman.
Let’s briefly introduce unpacking. All product accessories are here. The dimensions of the internal and external locks are the same, but the difference is the lock body. Therefore, users need to inform the type and dimensions of the lock body at home before installation. All accessories are also common, except for two more battery packs.
If you have seen Deschman R5, you will find that R7 is actually very similar in appearance, but R7 is more angular and looks slightly better. Deschmann R7 has two color schemes, besides the black one we got today, there is also a coffee gold one, which is quite compatible with the door.
The size of Deschmann R7 is 390*78*66mm. It should be noted that the smart lock should never be too small. The size like Deschmann R7 is actually just right. If the size or shape is too small, it will be very uncoordinated when installed on the door. After all, the door should pay attention to an atmosphere.
The surface of Deschman R7 is frosted, which makes it feel comfortable, and the aluminum panel also adds texture. The advantage of this material is that it will not leave fingerprints after use, and it also ensures the cleanliness of the appearance.
Let’s look at the external door lock first. The simple appearance is only printed with the words DESSMANN. Above the logo is a hidden keyhole. It should be noted that Deschman R7 supports five unlocking methods, namely 3D face recognition unlocking, fingerprint recognition unlocking, conventional key unlocking, droplet movement bracelet unlocking and a mobile phone remote unlocking.
On the back of the external handle is a square fingerprint recognition area, and Deschman R7 adopts semiconductor recognition technology, with the recognition rate as fast as 0.6 seconds. This kind of fingerprint recognition on the back is more convenient to use. When the sliding door is reached, it can be quickly unlocked, and the fingerprint recognition on the back is more concealed, which not only makes the appearance more unified but also protects the fingerprint recognition area. This design is quite good.
There is also a MicroUSB interface reserved at the bottom. Many smart locks have reserved this interface, which is mainly used to supply power to smart locks in an emergency. It can be charged with ordinary charging treasures. Although it is rarely used, it is of great significance.
The 3D face recognition of Deschman R7 can be said to be the core of the whole smart lock. From the picture, we can see that Deschman R7 uses dual cameras and has built-in SenseTime artificial intelligence 3D Sense.
ID
The algorithm calculates the depth information, and the recognition rate of artificial intelligence simulating human eyes is higher. The camera has a larger FOV field of view, which can easily identify people with a height of 130cm-200cm, and it can also realize the functions of active snapshot and discrimination, no matter day or night. It’s just that this naked 3D face recognition camera is a bit conspicuous. It would be better if it were made into a front hole-digging screen similar to a mobile phone. Of course, in that case, the technical requirements are higher.
There’s another design of Deschman R7 that I think is also well done, and that’s its digital unlocking design. It uses a hidden design, and it will automatically go out when it is not used. Only a doorbell button is reserved for visiting guests, and the design of distinguishing between subject and guest is quite good, so it can be said that its design is simple but its function is not simple. In addition, it also supports 16-bit virtual password to prevent peeping, and R7 also has built-in NXP security chip to protect information deeply.
Back view of Deschman R7
Compared with the external lock, the internal lock of Deschman R7 is more abundant. The internal lock panel has two anti-lock knobs and switch buttons. It should be noted that the close button inside R7 is also a Bluetooth button. Long press the close button can open the Bluetooth mode of R7.
Deschmann R7 supports indoor and outdoor one-button locking and automatic locking, which is really good for families with elderly people at home. Older people often forget to lock the door when they go out, or even put the key in the door lock and go out. With the automatic locking function, there is no need to worry about this problem, and users can set the locking time within 10-100 seconds, which is really convenient.
Deschmann R7 uses a detachable battery and is equipped with two rechargeable batteries. Two 5000mAh lithium batteries can be recharged and used alternately. The official claims that a single battery can last for 5 months.
Since it is a detachable design, the battery replacement should not be too troublesome. There is a power battery compartment on the internal panel of R7, which is convenient for disassembly and replacement.
R7 is equipped with a lock body of 240*24, which has to be equipped according to its own door. It is made of 304 stainless steel, and the interlocking tongue is also solid 304 stainless steel. At present, most smart locks adopt mechanical locks, which are hydraulic self-elastic locks, double quick locks and self-elastic+double quick locks. This time, it is equipped with double quick locks, which are characterized by simple structure, good stability and versatility.
Deschman R7 uses a C-class anti-theft lock core, which is also the highest-rated anti-theft lock core in China. This kind of multi-track lock core is the most widely used one because of its explosion-proof force, anti-technical unlocking and surface wire drawing technology, so it is also the most expensive one.
Deschmann R7 is also equipped with two emergency keys. Due to the special installation position of the lock core, the design of the key is also very special. It uses a folding key, which is twice as long as the ordinary key, just because it is worried that the rivet at the middle connection of the key will be easily damaged after long-term use. The key is milled with three grooves, which can effectively prevent technical unlocking, but the number of keys is less.
Many people will worry that the smart lock will not match the door at home. In fact, if the national standard door of your home, then R7 can be directly adapted to the original lock on the door without replacement. However, since the door in my home is an old-fashioned stainless steel door, the lock body must be replaced, and the installer needs to make holes in the door (free of charge when installing at home for the first time, including holes). Fortunately, the screw fittings are quite complete.
Deschmann R7 is installed, and the effect is quite good. Of course, it will feel better if it is installed on a wooden door.
APP
After the equipment is installed, you have to connect to the APP. You can easily connect by downloading the "Xiaodi Butler APP" according to the prompt steps. Even if the battery is replaced after the next power outage, there is no need to reconnect, and the APP is still very stable to use.
The interface of Xiaodi Butler is simple and clear, and the settings for Deshmann R7 are mainly on the home page, such as the management of equipment users, fingerprints, face management and so on. Users can also authorize to open the door, including random passwords and temporary authorization, and random passwords will produce 10 one-time passwords; Temporary authorization is to jump through small programs, and visitors can open the door within 5 minutes. Of course, every time you open the door, it will be recorded by the APP, and users can view the opening record.
Deschman R7 can input up to 30 faces, which can fully meet the needs of ordinary families. Although it is convenient to brush your face, many people may be worried, such as whether the dark light in the corridor can be recognized, whether the heavy makeup can be recognized, and whether the photo recognition can hide the sky. Let’s test it with me with these questions.
summary
From ordinary locks to fingerprint locks to today’s smart locks for face recognition, we can feel the convenience brought by technology. Deschman R7 is the first 3D face recognition smart lock I have ever used. From the experience of more than half a month, the biggest feature of R7 is intelligence. Many smart products are mostly made for young people. After R7 is used, grandma at home often praises this lock because she doesn’t have to bring a key or worry about forgetting to lock the door when she goes out.
Between fingerprint lock and face recognition lock, I think I should choose face recognition lock without hesitation. Deschman R7 is a good choice. Although it is not 100% perfect, for example, there is no remaining battery display on the APP, for example, there are too few keys, but this does not affect the intelligent experience it brings.
