Affected by the epidemic, the sales volume of smart locks in China will be 16.4 million after 2020, with a year-on-year increase of 17%. This is due to the diversification of products and higher consumer acceptance.

The development of smart door lock market benefits from communication and biometric technology

The development of smart door lock market is inseparable from the progress of communication technology and biometric technology. Before 2009, due to the limitations of biometrics, networking and other technologies, China's smart door lock products were scarce; After 2009, independent smart door locks with intelligent sensing and alarm functions began to appear; From 2015 to 2016, the networking mode was gradually mature, and the launch of networking lock was becoming more and more mature, which was the turning point of market expansion.

Communication technology affects the efficiency and stability of remote interaction, and biometric technology determines the reliability and security of unlocking performance. Compared with traditional keys, magnetic cards and passwords, biometric locks can be opened intelligently without carrying any tools or memory information. At present, biometric technology includes fingerprint recognition, face recognition, finger vein recognition and iris recognition.

Face recognition has become a new trend in the development of smart door locks

With the rapid economic development of artificial intelligence door lock industry, fingerprint lock is facing the situation of low recognition rate and enterprises can not liberate their hands. Face recognition information technology is rising.

• Advantages of face smart door lock recognition technology

⭕ Face smart door lock recognition technology has high accuracy. It is through the recognition and calculation of human face features, and compares the face smart door lock with the samples in the sample database, so as to obtain accurate results.

⭕ Face smart door lock recognition is a non-contact recognition. The image features of face smart door lock can be obtained without direct contact with the equipment.

⭕ It can recognize multiple people at the same time, and the features of face smart door lock within a certain lens range can be recognized at the same time.

⭕ Fast, compared with fingerprint acquisition and sound acquisition, the recognition speed is faster.

⭕ Enhance security. Facial biometric security system can greatly improve security. The identification system will quickly capture any entering personnel and remind them in time. Using the face recognition security system can effectively reduce the cost of employing security personnel.

⭕ High accuracy. With today's technology, face recognition technology has become more and more reliable. Due to the development of 3D face recognition technology and infrared camera, the current success rate is very high. The combination of these technologies makes it difficult to cheat the system.

⭕ Fully automatic. Before that, in order to confirm the match, safety protection personnel and various paper certificates are required to ensure the correct entry of personnel. Today, face recognition technology can now be fully automated and ensure its accuracy at a high speed. This means that it is very convenient to use and low cost.

• Disadvantages of face smart door lock recognition technology

❌ Face smart door lock recognition technology is not without harm. With more intelligent cameras equipped with human identification technology, people are more worried that their personal privacy has been leaked. Nowadays, many parks, roads and are equipped with cameras. They can also collect and store your video images under unpredictable circumstances. If these image information is not kept properly, it may be used by some people with ulterior motives to engage in illegal acts.

❌ Camera angle. Camera angle has a great influence on face processing. In order for the face recognition system to fully recognize the face, it needs multiple angles (including contour, front, 45 degrees and more) to ensure the most accurate matching results. In addition, any obstacles, such as facial hair or hats, affect the results. However, in order to prevent failure, the database constantly updates its data.

Although face smart door lock recognition has various advantages and disadvantages, with the advanced face recognition technology entering the market, I believe it will be more and more widely used and serve the society.
