In September 2018, when I was still in the technology vertical media, the horizontal evaluation of eight smart door locks allowed me to systematically understand the smart door lock industry for the first time, and now it has been four years.
Although RUNTO statistics show that the sales scale of China's smart door lock market in 2021 reached 16.95 million units, an increase of 5.94% year-on-year, and achieved the second consecutive year of growth, but the smart door lock in the appearance of the design basically remained unchanged, simple wind has been dominating, more changes are technology upgrades and function diversification.
The smart door lock that Fat Fat evaluated for everyone today is the new smart door lock equipped with macro light finger vein recognition under TCL - TCL finger vein smart door lock P10.
What is macro light finger vein recognition?
If you search Baidu Encyclopedia, you will find that it does not yet include the term macro light finger vein, but in fact, the core of the macro light finger vein refers to the vein, and macro light is a modifier, which is simply the way to achieve it.
So, what is finger vein recognition?
Finger vein recognition, as the name suggests, is to identify the vein vein texture distributed inside the finger, the finger vein texture contains a large amount of feature information, the probability of the same structure is one in 3.4 billion, although the number may be slightly higher than the probability of fingerprints, but its safety and practicality is much higher than fingerprint recognition.

Fat believes that there are two main advantages of finger vein recognition compared to traditional fingerprint recognition in the application of smart door locks.
On the one hand is security. Friends who often see crime-themed film and television dramas must have encountered such cases, that is, criminal suspects carry out crimes such as theft by taking fingerprints and making fingerprint films, which is a major hidden danger in the security of fingerprint recognition, that is, it can be copied.
Finger vein recognition recognizes the vein vein texture inside the finger, which is completely unreplicable and highly private, so it is obviously safer than fingerprint recognition.
Because of this, the identification technology has been widely used in banking and finance, government national security, and education and social security and other fields, for example, large-scale examination for the exam from time to time, the application of vein recognition will further eliminate the phenomenon of substitute examination.
On the other hand, everyone has used smartphones equipped with fingerprint recognition, have you occasionally encountered a situation where fingerprints cannot be recognized? This is mainly due to the relatively shallow fingerprint lines caused by fingerprint wear, peeling or water. Therefore, for the fingerprint line is relatively shallow for the elderly and children, or some people who often wear out fingerprints, then the sensitivity of fingerprint recognition has become a big problem, and the little brother who helps to install the lock tells fat that there are many door locks that use traditional fingerprint recognition to call the after-sales many times to show that fingerprint recognition is not sensitive.
Finger vein recognition itself is separated by a layer of skin, which needs to identify the veins and blood vessels under the skin, so even if your hands are stained with water and ash, or the fingerprint wear is serious, it is difficult to affect the recognition. Fat also found in the follow-up experience that finger vein recognition will be more and more sensitive, compared to fingerprint recognition practicality is significantly higher, later fat will be detailed.
According to TCL official data, the success rate of finger vein daily and wet finger recognition is greater than 98%, and the success rate of finger recognition on stain surfaces is greater than 95%.
After talking about finger vein recognition, the next fat for everyone to briefly introduce the TCL P10 method to achieve finger vein recognition, that is, macro light.
Macro light refers to the recognition module built-in macro camera, the macro lens can pass the "biometric + vascular texture composite verification" mode, each finger more than 300 finger vein feature points, a total of more than 2000 composite verification features for recognition.

The installation process is also very smooth and simple, first install the lock body, then install the C-class lock cylinder, and finally buckle the main body on both sides.
Smart and easy-to-use unlocking experience
TCL finger vein lock P10 contains 9 ways to unlock, namely finger vein recognition, NFC (mobile phone, watch, bracelet), card, password, key, APP remote authorization, and two-factor authentication (finger vein + password), the most commonly used way of fat refers to vein recognition, but it is recommended that you always have a mechanical key in the bag or in the car, in case the battery is out of power and other emergencies.
After the door lock is installed, when you use it for the first time, TCL Finger Vein Lock P10 will let you set the fingerprint administrator six-digit password, which cannot be changed or deleted in the App unless you restore the factory settings. Then, you can directly enter the finger vein according to the prompt, the single finger vein needs to be entered six times, and the numbers 1 to 6 below will have a light prompt and a voice operation method prompt.
Of course, we can also add finger veins, passwords, and cards through the mobile app, and after we operate through the app, we need to press "06✓" on the door lock to activate the door lock. It is worth mentioning that at this time, remote operation is supported, in simple terms, if your friends come to visit you, if you happen to be not at home, you can set the remote password to open the door through the operation, and when they leave, you can delete the password.
Regarding the actual experience of finger vein recognition, Fat found that when the finger vein was initially entered, TCL finger vein lock P10 would occasionally have unrecognizable problems, but with the accumulation of time and the number of uses, the finger vein recognition became more and more sensitive, simply put, the more it was used, the more useful it was. After a long time of use, when the hands are sweaty or the hands are dirty after just finishing the ball, the P10 can also be sensitively recognized.
As for other smarter settings, such as when a visitor appears outside the door, the doorbell welcome light effect of the TCL finger vein lock P10 will automatically light up to remind the visitor to ring the doorbell.
At the same time, the app will receive a reminder when each family member returns home. Parents can also set a timeout reminder for children to go home in the App, such as if you work overtime in the company, if your child does not come home on time after school, the App will notify parents in time to ensure the safety of the child.
In addition, if your home happens to be a TCL smart TV, then the TV and door lock can be interconnected under the same WiFi, and when the visitor presses the doorbell, the TV will pop up to remind and unlock remotely.
Write at the end
At present, there are not many finger vein smart door locks on the market, and TCL can be said to be the earliest batch of finger vein recognition applied to the field of smart door locks. From the actual experience, finger vein recognition is indeed more useful than traditional fingerprint recognition, and when you understand its principle, you will find that it is also more secure than traditional fingerprint recognition.
Of course, the shortcomings of finger vein recognition also exist, such as higher cost, large area of identification area, but the current TCLCL finger vein lock P10 price is only 2499 yuan, 618 period want to change the lock is completely worth considering.
