Many people are no strangers to smart door locks. Its appearance has improved the situation of "one key opens one lock". Through the unlocking method of fingerprints and passwords, we no longer need to carry keys with us, which greatly facilitates our daily life.
However, as of 2018, the data show that the penetration rate of smart locks in Europe and America is 35%, and that in Japan and South Korea is 60%, while in China it is only 5%. It can be seen that with the continuous warming of the consumer market, smart locks will be a huge incremental market in the future, and more diversified products are needed in the market.
Not long ago, Xiaomi launched a brand-new smart door lock-Xiaodi face recognition smart lock R5, which is different from the traditional fingerprint or password unlocking method, but took the lead in applying face recognition technology to smart door locks. Titanium Media also tested this product for the first time.
Perhaps many users haven’t heard of Xiaodi’s brand smart lock, but in fact it is not a brand new brand, and Deschman behind it is the leader in the smart door lock industry, and properly hides "mr. six".
Deschman entered China in 2009 and has been focusing on smart home and security. At present, it is one of the few smart lock enterprises with complete industrial chain, independent research and development capability and nationwide after-sales system. Up to now, it has expanded more than 3,000 retail outlets, covering installation and after-sales service in most cities.
As a young intellectual brand owned by Deschman, Xiaodi has previously launched some products such as automatic smart lock Q3 and smart fingerprint lock H3, which have achieved good results. Today, the new product Xiaodi face recognition smart lock R5 has opened up a new dimension of product experience.
Good adaptability and the highest safety level.
The design of Xiaodi’s face recognition smart lock R5 is conventional, with two colors to choose from: high-end black and coffee gold. Xiaobian got this one with high-end black color, and the overall shape is very three-dimensional. The inner and outer panels are carefully frosted, with two physical buttons on the inner side and a hidden password touch password panel on the outer side.
Open the product package, and the Xiaodi face recognition intelligent lock R5 contains a lock core, two batteries and two keys in addition to a door lock theme. There are a number of other screw fittings, but the use positions are all marked, and a Xiaodi is attached to the package.
The structure diagram of R5 and the opening diagram of keyhole are convenient for users to understand its structure.
Xiaodi face recognition smart lock R5 comes standard with a C.
As we all know, the anti-theft door lock core used in the market is basically divided into three levels, namely, level A, level B and level C, and the latter belongs to the highest level. If the lock core is opened with a strong twisting tool, the lock core will explode and lock itself after being damaged, resulting in failure to open it.
Titanium Media Xiaobian found that Xiaoyan’s face recognition smart lock R5 is also equipped with two traditional mechanical spare keys in case of emergency. When you encounter problems such as battery dead or firmware upgrade, you can use the spare keys to insert them into the lock core for mechanical unlocking.
The capacity of the battery greatly affects the user’s experience. Two 5000mah batteries are standard on the small R5.
The user can use two batteries alternately, which fully guarantees the service life of the smart door lock. According to the actual use, at present, one battery has been used for one month and has not been prompted to be replaced.
In terms of installation, as long as the home is a national standard door, there is no need to measure the size specially when purchasing. The intelligent lock R5 of Xiaodi’s face recognition can be directly adapted to the original lock body on the door. If it is a non-national standard door, it needs to be replaced with a lock body that comes with Xiaodi.
However, there is also a disadvantage. Take the door tested by Xiaobian as an example, before installing the smart lock, there is a "heaven-earth hook" (its function is to increase the number of pop-up locking tongues on the top and bottom of the door, so that the door can be more firmly fixed on the door frame). Xiaodi’s face recognition smart lock R5 theoretically supports the heaven-earth hook, but if it is replaced with Xiaodi’s own lock body, the heaven-earth hook may not be 100% usable, which is also related to the size of the lock body.
It takes about two days from the receipt of the lock to the appointment of the master to install it at home, and the installation process is not long, only about half an hour. Generally speaking, no matter the convenience of installation or the ease of use, the threshold for getting started of Xiaodi face recognition intelligent lock R5 is not high, and the next step is the specific use.
3D face recognition, brush your face and open the door in seconds.
As a product of Xiaomi Eco-chain, Xiaodi face recognition smart lock R5 naturally fits Mijia APP perfectly, and its connection method is not much different from other Xiaomi intelligent hardware. First, turn on Bluetooth and manually add devices. Search Xiaodi face recognition smart lock R5 and click Connect.
Because it is a beta version, you will be prompted to update the system after connecting the lock to the APP for the first time. After updating to the latest version of the system, you will be prompted with a six-digit verification code on the APP side. Enter the verification code into the keyboard of the door lock to complete the verification pairing successfully.
After the equipment is successfully added, the first thing to do is to set the face key. In the process of entering the face, it is necessary to keep the facial features clearly visible, avoid wearing obstacles such as hats or masks, and try to keep enough light. You can enter multiple "face keys" at the same time.
However, from the actual unlocking experience, the requirements are not so harsh. The situation of wearing glasses can basically be unlocked normally, but the hat will block the light, which will cause some unrecognizable situations.
After installation
According to the data, Xiaodi R5 adopts the bionic binocular 3D face recognition algorithm integrated with sensetime, a global face recognition giant in Shang Tang. The data comes from sensetime’s face recognition laboratory. It generates a 3D face model by simulating the principle of human eye imaging. Compared with 2D face recognition, Xiaodi R5 is safer and can learn facial texture content by itself, with a false recognition rate of less than 0.0001%.
, which can effectively prevent the attack of unlocking with photos.
In the process of unlocking, face recognition will be triggered automatically. With a larger FOV field of view, Xiaodi R5 can easily identify people with a height of 130cm-200cm, and does not need to bow or raise its head to adapt to the camera angle.
The use scene of the smart door lock is very fixed, that is, in the corridor, but the lighting level of the corridor in different buildings is not the same. If the light is bright, it will not have much impact. If the light is dim, it will test the success rate of the smart door lock recognition.
In order to solve this problem, the scheme adopted by Xiaodi’s face recognition intelligent lock R5 is to add an infrared fill light, which can generate depth information by combining with 3D dual cameras under the condition of unsatisfactory light. The actual test shows that the accuracy is very high, and it can be quickly unlocked by natural light even without turning on the light.
In terms of password setting, Xiaodi R5 provides several different modes, including password unlocking, face recognition, and password+face. Among them, "password+face" is a dual verification mode. First, you check the face information, and then enter the password to unlock it, which means that only you can unlock it, which can ensure security to a great extent.
Xiaodi R5 can also turn on the one-button protection function when traveling. If a thief enters the room through a window or other means, when he goes out by pressing the button in the room, the lock will immediately give out an alarm sound for 15 seconds and send the alarm message to the mobile APP, so that users can monitor the safety of their homes in real time even when they are away from home.
On the Mijia APP, we can also adjust the information such as the torque of the door lock, the direction of the motor, the volume of the prompt, etc. There is a very intimate detail, in which the user can set the distance of human detection and reduce the number of times passers-by activate the lock, otherwise anyone passing by the door will automatically activate the lock, which will also lead to an increase in power consumption.
As mentioned earlier, Xiaodi R5 has a 5000mAh dual lithium battery configuration that is rare in the industry. The official data is that one battery can be used for 5 months, and it is more convenient to charge and recycle two batteries in turn. When the battery of the R5 is less than 15%, there will be a voice prompt for charging every time you open the door, and the battery sign on the keypad will also be bright red. If all the batteries are dead, you can also use the USB charging treasure to activate the lock for emergency unlocking.
One-time password for opening the door is a regular function, and this function is also standard on the small dial R5 without exception. When a friend visits, a six-digit temporary password can be generated on the Mijia APP, and the validity period of the password can be set and sent to relatives and friends to open the door locally.
summary
After a period of experience, with the key of "face", Xiao Bian has become accustomed to going out without a physical key. Compared with some products unlocked by fingerprints on the market, Xiao Di R5 is not only more cool in unlocking mode, but also guaranteed in terms of security.
It’s just a pity that Xiaodi R5 doesn’t provide a fingerprint unlocking module, which means that users can only use it for face recognition. If users are used to unlocking with fingerprints before, they may need to adapt to it for a while.
With the wave of smart home, smart door locks are gradually becoming popular, and the functions of smart door locks are becoming more and more abundant. Face recognition is one of the technologies widely used in smart phones at present, and Xiaodi, a young intellectual brand owned by Deschman, is also following the trend, and R5 is a good embodiment.
As for whether the category of smart door locks will gradually transition from fingerprint unlocking to face recognition like smart phones in the future, it needs the verification of the market and consumers, but there is no doubt that as long as the security is high enough, users will always choose a more convenient way.
