Today, smart locks are already very common home security products, which not only liberate the key, but also carry more home experience and security protection. Many people's smart locks are now not just password locks and fingerprint locks. More technologies have been added to the smart lock, such as 3D face recognition technology unlocking, finger vein technology unlocking and so on.
3D face recognition smart lock is one of the most popular smart lock unlocking methods in the past two years, and smart lock manufacturers such as Xiaomi, TCL, and Huawei have entered the game.
Before saying that the value is not worth starting, first popularize face recognition for everyone, and those who do not want to see it can directly slide to the back to see the horizontal review.
Before popularizing science, first insert the 2D face recognition that has gradually become history.
It has long been widely used in the field of public safety, such as face authentication, road monitoring, etc. 2D face recognition is mainly based on the camera to shoot face graphics and convert them into digital signals, and then use computers to extract, analyze and match faces on the graphics.
However, 2D face recognition is susceptible to lighting and shooting angles. More importantly, with the evolution of offensive and defensive technology, 2D face recognition is not enough in scenarios that require high security such as face brush payment, mobile phone unlocking, and home security, and the door lock is the first gatekeeper of the house, which is not a joke.

At present, smart door locks use more 3D face recognition technology is "binocular stereo vision" and "3D structured light" these two, these two technologies are actually not strange to us, we use mobile phones every day, has long used these two technologies.
So, in the end, 3D face recognition is not safe?
This we basically do not have to worry, the current big brand of 3D face recognition manufacturers, security is certified by the state. But here is a brief mention, we must not buy too cheap 3D face recognition smart lock, I see sometimes vibrato will have what 999 yuan 3D face smart lock, this we still have to be cautious. The cost of smart locks is very transparent, a penny for a penny, poor face recognition module will affect security, there may be a "take a picture can open the door of your home", "take a fake head mold can open" this situation.
At present, what is the better 3D face recognition business of smart lock?
Mainly recommended 4 to everyone: Xiaomi, TCL, Huawei, Cadiz
I will not recommend the rest of the white cards.
So how much do they cost? I summarized a horizontal review form for everyone. People can choose according to their budget and needs.
Basic function options I will not write, these big brand basic functions are almost the same, so the core cost performance also added the "big screen cat's eye" function, the big screen is basically the most mainstream function at present.
Price comparison chart
To sum up!! Scratch the point!
The most cost-effective: TCL 3D face recognition cat's eye lock X9S wins
Plug in, their X7S, X10 and other 3D face recognition modules are also the modules of Obi Zhongguang - the trump card of the 3D structured light module.

Of course, if you have Huawei or Xiaomi smart home products at home, you can also choose these two! After all, the linkage is convenient, but to be honest, Huawei's cost performance is indeed not high. Xiaomi is still good!!
summary
Finally, I still want to remind everyone not to buy 999 face recognition smart lock! Don't buy miscellaneous cards! Don't buy something you haven't heard of! Look for big names!!!!
Pay attention to me, ten years of home appliances old driver, buyer electricity does not get lost!
