First model: Huawei smart lock pro

Huawei – a new force in Internet home appliance brands

It is also a 3D facial recognition smart lock, but this product is actually more expensive than brands that specialize in smart locks. Its biggest advantage is that it is deeply integrated with the HarmonyOS smart ecosystem, and the Huawei smart screen at home can also view what is happening outside the door. 3D face recognition technology can be activated as soon as you swipe your face, and it will also learn faces through AI, so the more you use it, the more accurate the recognition will be.

In addition to face recognition, unlocking methods include fingerprints, virtual passwords, temporary passwords, encrypted NCF cards, keys, Huawei mobile phones, and Huawei watches. However, for friends who are not Huawei end users, it has very few unlocking modes, and the smart linkage scenarios are not useful.

Second model: Desman R7F Pro

Deschman – an old brand of traditional smart locks

Big Some people say it is a German precision door lock, but in fact it is a domestic brand, not imported. It uses a binocular infrared camera, equipped with a 3D face recognition algorithm, and can also scan your face to open the door. There is a smart video doorbell function, but there is no visual screen. The APP pushes alarm information and checks the activities outside the door.

In addition to the conventional unlocking methods, there is also double verification. Two of the 10 unlocking methods are optional, so there are not many unlocking methods. There is a mechanical rear handle, which is also very convenient for indoor unlocking.

Third model: Caddis K20 Max

Kadishi – a traditional smart lock brand

The fourth model: TCL K7G Pro

TCL – the leading smart lock brand for many years

TCL is not only TCL K7G is a well-known home appliance brand in China and has been a leading smart door lock brand for many years. Pro uses 3D structured light face recognition technology to open the lock in seconds and is not affected by light. It can be recognized even if you wear a hat or change your hairstyle or makeup. If you have elderly people at home, you don’t have to worry about not being able to use it. You can open the door immediately when you stand in front of the door.

3D face structured light recognition technology is a method that uses light mapping toThe advantages of this technology are its accuracy and strong adaptability to environmental changes. Since it is based on three dimensions, it is not easily deceived by flat pictures or other two-dimensional simulation means. Likewise, it also has certain anti-counterfeiting properties and can effectively identify attempts at occlusion or imitation. This determines that TCL K7G Pro is both convenient and safer.

TCL K7G Pro also has a 165° super wide-angle cat eye and a high-definition visual screen on the rear panel, so you can check what’s going on outside the door at any time. If there is express delivery or takeout delivery, friends who live alone can use AI voice change to talk to visitors, which is quite safe.

There are 10 unlocking methods. In addition to the conventional unlocking methods, there is also NFC for mobile phones/watches/bracelets, which is more convenient. TCL K7G Pro has a TCL speed chip, which can quickly unlock + a variety of algorithms to protect users\’ personal data and protect security and data security.

In comparison, there is not much difference in the technical security of these four 3D facial recognition smart door locks, because they are all technologies that have reached the financial payment level. . As for the lock cylinder, these four models all use the highest level C-level locks. In terms of security functions, abnormal information such as trial and error, stay, and door prying can be captured and pushed to the mobile phone. In terms of remote dialogue, TCL and Deschmann. All can change their voices with AI, which enhances home security. The K7G Pro is the cheapest among the four, but it also has a 3.5-inch visual screen, which allows you to view the situation outside the door in real time, which can still give people a more sense of security.

So, the information that sales want to instill in us that \”the more expensive the smart lock is, the safer it is\” is not entirely correct. We should try our best to buy facial recognition smart locks. Perhaps comparing technology, lock cylinder level, security functions, etc., the safety performance is almost the same, and other aspects are more about the use experience
