For door locks, one of the most important functions is security, especially in this era of the Internet, the security of smart door locks is very important. We can also see that the current technology of smart door locks is being upgraded step by step, from the original password, fingerprint recognition, finger vein recognition, to the current face recognition that can be unlocked without touching at all.
However, there are many solutions for face recognition alone, such as upgrading from the earliest and easiest to crack 2D face recognition to 3D face recognition, and then 3D face recognition includes binocular recognition, TOF, 3D structured light recognition, among these recognition schemes, the most secure is 3D structured light face recognition.
The 3D structured light is projected onto the photographed object through the infrared light projector, and then collected by a special infrared camera, which mainly uses the principle of triangle similarity to calculate, so as to obtain the depth information of each point on the image, and finally obtain three-dimensional data, so as to create an accurate 3D facial model. Compared with TOF and binocular stereo vision, it is more rigorous. However, most of this technology appeared on the smart door lock of 2-3000 yuan, until the emergence of TCL 3D face recognition cat's eye lock K7G Pro, which pulled the price to 1199 yuan in one fell swoop, and the cost performance is very good.
In addition to the use of 3D structured light, a financial-level face recognition technology, TCL has also specially developed a smart speed chip to cooperate with TCL's AI self-evolving face algorithm, which can maintain a high pass rate even in complex light scenes, or when users wear makeup and glasses. And K7G Pro's 3D face recognition function also supports AI feature point self-learning, which will become more and more familiar with the user's face, thereby improving unlocking speed and convenience.
In addition, K7G Pro is also equipped with an electronic peephole function with an angle of up to 165°, through a built-in millimeter-wave radar that can work 24 hours a day, it not only provides real-time monitoring functions, but also captures and pushes warnings for whether there is someone staying outside the door, so as to prevent it in advance, and also leave corresponding evidence. In addition, the electronic cat's eye also supports two-way video calls, AI voice changing and other functions, allowing users to communicate with visitors at the door remotely, remote unlocking and other operations, it feels like a 24-hour security guard for the home, monitoring the security outside the door at all times.
As a cost-effective automatic smart door lock,TCL K9G ProHanging a crowd of 2-3000 yuan smart door locks at a price of more than 1,000 yuan,3D structured light plus self-developed chips and algorithms are to build a solid city wall for the family,Not only the more you use it, the more you use it, the safer it is,This is a product from a traditional home appliance manufacturer,It's really fun to roll it up,If you meet your needs, you may wish to consider it,It's definitely a value-for-money choice。
