How to choose a smart door lock? TCL released three flagship smart locks to show you the black technology of 10.

With the continuous development of Internet of Things technology, more and more families begin to use smart door locks. Compared with the traditional key door lock, it has too much convenience and higher security. But for many small partners who want to install smart door locks, they usually don't know how to make brands and models. I personally have a deep understanding.

When I first moved a few years ago, I spent more than 3000 yuan to buy the first "smart" door lock under the "flicker" of the residential property. After using it, I realized that it was not smart at all, because even the APP and mobile phone could not be accessed, and there were only several functions such as fingerprint unlocking, password unlocking and NFC unlocking. It took nearly two years to find many problems. The most terrible thing is that the northern winter is dry, and fingerprint unlocking is very insensitive.

Later, after listening to a friend's recommendation, I started with the TCL intelligent door lock K7Q. The original intention of starting this product is because it integrates the function of visual cat's eye. A camera with a wide angle of 175 degrees and a pixel of 1 is installed on the lock body outside the door. There is a 3.5-inch high-definition IPS color screen on the lock body inside the door. When you ring the doorbell, you can see the situation outside the door through the screen. Especially friendly for a family with two little babies like me. Children can see the situation outside the door and will not easily open the door to strangers.

Although TCL is not a pioneer in the smart lock industry (starting from 20 19), the iterative update speed of products is still relatively fast. Focusing on the purpose of "visibility and safety", K7Q, X7S and other explosive products have been launched successively. On April 2nd1day, TCL held the spring new product launch conference of visual security smart lock 2022, and released three series of smart door lock products: X 10, C 10 and P 10. As the flagship product of TCL visual safety, there are still many selling points of three-door locks; It mainly includes ten black technologies such as true 3D face recognition, full-scene visible cat's eye, macro finger vein recognition, "Honghu" home security system and child safety protection. Let me give you a brief introduction, hoping to help friends who plan to start smart door locks.

Real 3D face recognition

For the new X 10, the biggest selling point is to carry true 3D face recognition technology. We all know that the current smart door lock has transitioned from fingerprint unlocking to finger vein unlocking and 3D face unlocking, especially face unlocking, which can bring greater convenience, sense of technology and sense of ceremony to life. For example, you can't open the door when you go home with children and vegetables in your arms. At this time, you only need to brush your face to open the door, which is very convenient. But for this way of opening the door, security has always been a concern of users.

In this regard, TCL and Obi-Zhongguang, the world's leading provider of 3D visual perception technology, developed this face recognition module, which can project more than 28,000 projection points, accurately identify the position and depth of the user's five senses, and the recognition speed is less than 1.3 seconds. At the same time, it can effectively prevent the cracking of plane images, mobile phone videos and even simulation headgear, thus greatly improving the security, recognition accuracy and speed. This face recognition module supports the recognition range of 1.3-2 meters, and even children at home can use it normally.

Full-scene visible cat's eye

I always think that the cat's eye function is still very important for a smart door lock, which is also an important reason why I started K7Q before. The TCL visual security smart locks X 10 and C 10 released this time are equipped with full-scene visual cat eyes. With the 150 super wide-angle cat-eye camera and 4-inch local large screen, users can wake up the cat's eye at any time to check the situation outside the door through the smart lock screen and TCL App, or they can use the cat's eye to make 1080P HD video calls with visitors outside the door. When you are not at home at ordinary times, it is much more convenient to come to guests or sign for express delivery. Especially for families with small babies, it is recommended to buy smart door locks with cat's eye function.

In addition, TCL smart lock can be interconnected with TCL smart screen and TCL App. When a visitor rings the doorbell, a notification reminder will pop up on both the smart screen and the mobile App. Users can remotely view the cat's eye through the smart screen and mobile App, or remotely authorize and unlock it using the smart screen and mobile App.

Macroscopic optical finger vein recognition

For the new product P 10, the biggest selling point is vein technology identification technology. There may be many friends here who are a little strange to this, so let's simply popularize science; Finger vein technology realizes the function of individual identification by quickly scanning the subcutaneous capillary layout of human fingers. Because vein belongs to internal physiological characteristics, it is the only biological key for everyone. By sampling and identifying more than 300 feature points and more than 2000 blood vessels of each finger, the recognition sensor not only has a stronger recognition safety factor, but also has a higher recognition efficiency. Therefore, compared with fingerprint identification technology, finger vein technology is suitable for a wider range of people, and is also suitable for users with shallow fingerprints such as the elderly and children. Especially in families with elderly people, the recognition accuracy is higher, and the rejection of fingerprints cannot recognize the rejection.

"Honghu" Home Security System

In addition to the necessary hardware support, the system is also very important for a smart door lock to work well. TCL Visual Security Smart Lock 10 is equipped with "Honghu" home security system, which supports three software security technologies: trusted OTA system upgrade, one machine with one secret and secure network. OTA upgrade can be understood as an online upgrade system, which can prevent the smart lock from being tampered with the upgrade package by hackers when upgrading, leaving a crack hole; One machine with one secret is equivalent to the fact that both the door lock and the access card have unique corresponding equipment codes to prevent criminals from copying the unlocking card; The smart lock realizes the "point-to-point" connection with the network through the Internet of Things network security system of Honghu system, and prevents hackers from hijacking and invading the smart home system through the network.

Child safety protection

As a parent with two babies like me, one function I should pay attention to when choosing the door lock is child safety protection. All three new TCL door locks have protective functions. Parents can set their children's overtime home reminders through TCL App. When the child doesn't get home within a limited time, the smart lock will send a notice to the TCL App at the parent's end to inform the parents of the abnormal situation at home in time. In addition, the child lock function can be opened with one key, and the door opening button of the internal lock will not be used after opening, so as to prevent children from touching the door by mistake.

Of course, in addition to the above selling points, the three smart door locks have many features, such as NFC full compatibility unlocking, dual charging, radar wave sentry mode, unlimited intelligent optical interaction and so on. Through this conference, we can see TCL's strong technical research and development capabilities in the field of smart door locks. I believe that with the continuous updating of products, it will definitely form an industry competition barrier that only belongs to TCL.

Personally, I'm going to start with the product X 10, because it not only has the function of large-screen visual cat's eye, but also has 3D face recognition, which is simply suitable for my family with both old people and children. The previous K7Q product is ready to be removed and installed on the door of my hometown. Yes, I forgot to mention that the disassembly and assembly of TCL is free, so users don't have to worry.
