HarmonyOS adds another capable player, Huawei releases the first Hongmeng smart door lock, using HarmonyOS financial-grade security architecture to protect residential safety

At a time when Generation Z, who are willing to spend to please themselves, have become the main force of consumption, "how to improve the quality of life" has been dominating the charts on social media platforms such as Zhihu and WeChat official accounts. In previous years, the charts were filled with new species such as "dishwashers" and "sweeping robots", but now they are gradually being overshadowed by a household essential product that has been with us for 5,000 years: the door lock.

GfK survey data shows that 62% of Chinese consumers are willing to buy smart door locks, ranking first in the smart home category.

The logic behind this is also simple and clear. Door locks, which have appeared since the Yangshao culture 5,000 years ago, have long proved themselves indispensable in people's lives. After being endowed with more functions by the wave of intelligence, it naturally brings more improvements to our quality of life due to its high frequency and necessary usage attributes.

I believe everyone has experienced the embarrassment of forgetting to bring keys when going out. Whether waiting for someone to send a spare key or summoning a locksmith, whether going out to work or buying groceries, it is undoubtedly an extremely annoying experience, so much so that the cordless phone advertisement "I'm locked out" can be caught and widely circulated.

Of course, nowadays we no longer have to beat around the bush to solve the problem of door keys, because we now have smart door locks.

When smart door locks were first introduced, they were designed to solve the problem of convenience. With extremely high usage frequency, not having to carry keys or worry about forgetting keys is enough to support the huge market for smart door locks.

However, after replacing traditional mechanical locks, smart door locks have not stopped their pace. In the process of continuous iteration of intelligence, they have played more roles. Especially after being integrated with smart homes, as an intermediate medium to isolate users' home space from the external environment, they have become the trigger center for scene conversion. Their importance is self-evident.

As the whole-house smart concept gradually gained popularity, Huawei's IoT layout has become increasingly complete. Recently, Huawei finally released its first series of HarmonyOS smart door locks. And Huawei, which has always been known for its quality, did not disappoint. Huawei's smart door lock series not only supports many new features in product hardware, but also perfectly integrates the Harmony distributed system in terms of functions. In terms of experience, it solves many pain points in the industry and sets a new benchmark for the smart door lock industry.

AI 3D face recognition + AI fingerprint unlocking solves industry recognition pain points

How to solve the problem of taking keys with you when you go out? It's very simple, just unlock the car without keys.

We have already used various biometric technologies on our mobile phones, using fingerprints and facial features to replace lock screen passwords, which improves security and convenience at the same time and has quickly become a standard feature of smartphones.

It is only natural to extend this concept to smart door lock products.

The cheapest solution is fingerprint unlocking, but the fingerprint solution that performs well on mobile phones does not perform well on door locks. This is because mobile phone users are usually only one person, while smart door locks are for the whole family. For children whose fingerprints are still shallow and the elderly whose fingerprints are severely worn, fingerprint unlocking of door locks in the past is very unstable and may even be completely unusable.

Huawei Smart Door Lock Pro supports AI 3D face recognition, which can unlock the door by identifying the user's facial features. It is more secure and is undoubtedly more suitable for smart door locks. However, whether it is 3D ToF or 3D structured light, the hardware cost is higher, and it also requires stronger machine learning capabilities at the software level to continuously learn and recognize changes in the user's face.

In addition to biometrics, password unlocking, smartphone and watch unlocking, and NFC card unlocking have added a step of taking out the device, which reduces the convenience, but they are also widely used due to the low adaptation cost.

When it comes to Huawei, she chooses “I want it all.”

Huawei smart door locks support AI fingerprint unlocking, Huawei mobile phone and watch one-touch unlocking, remote temporary password unlocking, etc. Huawei Smart Door Lock Pro adds 3D ToF face unlocking function on this basis, which is more secure and convenient.

Of course, friends who are familiar with Huawei's tone will not find it difficult to notice that Huawei still adheres to the past product design concept of "I have what others don't, and I am better than others" in its smart door lock series.

In terms of fingerprint recognition function, Huawei's smart door lock series is committed to using AI algorithms to solve pain points.

After the first entry, Huawei's smart door lock series will continue to learn fingerprint characteristics during use, making the fingerprint matching degree and recognition rate higher and higher.

To address the problem of insensitive fingerprint recognition for the elderly, children, and wet hands, Huawei has adopted three major functions: AI fusion, AI adjustment, and AI feature point recognition. By splicing multiple incomplete fingerprints, automatically adjusting the direction of fingerprint texture, and identifying deeper fingerprint feature points, it can obtain more than 10 times the industry average level of fingerprint information, so that special groups such as the elderly and children can also get a consistent user experience.

In terms of 3D face recognition technology, Huawei Smart Door Lock Pro uses the same AI dynamic learning algorithm and hardware as its flagship mobile phone. After training, it can accurately identify user facial features in different scenarios such as makeup, wearing glasses, wearing hats, and environmental changes. It also continuously updates the user's facial model during its years of service, making the door lock better and better.

At the same time, Huawei Smart Door Lock Pro also uses a 3D deep-sensing liveness monitoring algorithm that can identify materials such as silicone, plaster, nylon, and plastic, and resist attacks such as photos, videos, masks, hoods, and head models, with a false recognition rate of less than one in a million.

In terms of specific user experience, the 3D depth-sensing camera of Huawei Smart Door Lock Pro is arranged at an upward angle of 16° and covers an angle of 78°. It is suitable for users with a height of 1.2 to 2 meters, and the side face angle within 45° can be directly unlocked. Users do not need to deliberately tiptoe, bend over or adjust their standing posture during use, achieving convenience that exceeds fingerprint recognition.

For users, using Huawei's smart door lock with fully automatic lock body can experience the ultimate convenience of opening with one grip and locking with one close, as if this door lock does not exist at all.

Safety should not be compromised for convenience

Of course, a good smart door lock needs to provide users with an experience that is as if it does not exist, and at the same time appear to be as solid as a bank vault to people other than the user.

It has to be admitted that when smart door locks were first introduced, security was completely subordinate to convenience. After providing a convenient unlocking method, the security is even worse than that of traditional mechanical locks. For example, many smart door locks do not support the top and bottom hooks of anti-theft doors, and many smart door lock systems can be easily hacked by black boxes.

Fortunately, with the development of the industry, the products of regular brands of smart door locks are gradually becoming standardized.

Huawei has once again pushed the security of smart door locks to a new level. Huawei smart door locks are the only smart door locks in the industry that adopt a financial-grade security architecture, achieving a full range of "financial-level" security protection including CCRC enhanced security certification for the entire system + Harmony TEE OS software CC EAL5+ security certification + hardware EAL5+ security certification for security chips, leaving users with no security worries.

On top of the extremely secure underlying architecture, Huawei has also carried out a large number of redundant designs to ensure user safety.

For example, in terms of battery design, Huawei's smart door lock series uses a dual battery compartment design + 8800mAh large battery for ultra-long battery life. The battery life in smart battery life mode (face & cat's eye function turned on) can reach 6 months, and the battery life in ultra-long battery life mode (face & cat's eye function turned off) can reach 12 months.

In order to prevent the embarrassing situation of locking the user out of the door due to a lack of power in the door lock, Huawei smart door lock uses a dual battery intelligent management system of lithium batteries and dry batteries. There is no need to shut down the machine to replace the lithium battery. In special circumstances, if the lithium battery runs out of power, it can be switched to a dry battery to continue powering basic functions.

Even if the door lock is completely out of power, Huawei Smart Door Lock supports emergency power supply via the Type-C port. Huawei Smart Door Lock Pro also supports wireless emergency power supply. Users can use a mobile phone that supports reverse wireless charging to power the door lock to temporarily open the door. This is a very thoughtful idea, allowing users to completely say goodbye to battery life anxiety.

Huawei's attention to the security of smart door locks can also be seen in the polishing of software design details. For example, Huawei has specially designed a feature for the Smart Door Lock Pro that automatically disables the face recognition function for 10 seconds after the door is closed and locked, to avoid the problem of misinterpretation of the lock that may be triggered when the user turns back to confirm whether the door is closed after going out. This also shows that Huawei's smart door lock products are extremely complete in terms of software and hardware design.

Intelligence, wonderful because of ecology

If the convenience of unlocking and the security of locking are still the iterative upgrades of smart door locks based on traditional mechanical locks, then the connection with smart home systems is the new attribute that allows smart door locks to be reborn.

As mentioned earlier, smart door locks are not only the intermediate medium that separates the home space from the outside space, but also the first device we touch when we arrive home and the last device we touch when we leave home. In the wave of whole-house intelligence, it is not only the "gatekeeper" of family security, but also the repeater of the smart home status.

As the world's first HarmonyOS "gatekeeper", Huawei's smart door lock series not only provides extremely high convenience and security, but also provides distributed visual cat's eyes and door lock inner screens, providing users with an eye looking outside the door.

With the support of HarmonyOS distributed technology, the image of the visual cat's eye can not only be displayed on the built-in screen, but also can be directly projected to the Huawei Smart Screen in the form of picture-in-picture when the doorbell rings. Users who are watching TV can intercom and open the door without even getting up.

Of course, if the user is not at home, he can also communicate with the tenant remotely through Huawei mobile phone and visual cat eye, or directly send a remote offline temporary password to allow the tenant to temporarily enter the house. When you are not at home and a courier is delivered to your door, you no longer need to ask the courier to put the package at the collection point.

In order to address potential hidden dangers outside the door, Huawei smart door locks also provide a PIR (passive infrared detection) function. Combined with AI monitoring technology, it can intelligently eliminate images of normal passers-by and only capture abnormal situations of staying outside the door, providing users with effective information that may cause safety hazards in a timely manner.

It is worth mentioning that Huawei's smart door lock series all support WiFi connection without the need for a Bluetooth gateway. Users can not only connect to view the cat's eye information at any time, but Huawei also provides up to 7 days of video rollback to ensure that key information will not be overwritten by new information.

As one of the companies with the most comprehensive smart home ecosystem in the world, Huawei relies on its "1+8+N" full-scenario strategy and implements an end-to-end collaborative solution of cloud, pipe, terminal, and core to provide users with the widest and deepest IoT smart home product interconnection ecosystem. Each Huawei smart home product, in collaboration with numerous HarmonyOS Connect devices, can cope with more and more application scenarios.

The same is true for smart door locks. The state of the door lock being opened or locked can be used as an identifier of the user's homecoming or leaving home, enabling a wide range of smart scene settings. For example, after returning home, the speaker can broadcast a welcome message, play music, turn on the lights, turn on the air purifier, etc. When leaving home, the lights can be automatically turned off, the sweeping robot can be started, the camera can be turned on for defense, etc., bringing more possibilities to smart homes.

To sum up, although Huawei's smart door lock series products did come a little late, they have indeed achieved comprehensive leadership in functionality, security, intelligence, etc., and set a new benchmark for high-end smart door locks.

For those outside the door, it is an insurmountable barrier; for users, it is a "door god" who is so considerate that its existence can be ignored; for Huawei's smart home ecosystem, it is an excellent housekeeper who arranges smart home appliances to adapt to different scenarios at any time. From any perspective, Huawei's smart door lock series is an excellent high-end smart door lock, especially for consumers who are already in the Huawei ecosystem.
