The development of the smart door lock market benefits from communication technology and biometric technology. The development of the smart door lock market is inseparable from the advancement of two core technologies—communication technology and biometric technology.
Communication technology affects the efficiency and stability of remote interaction, while biometrics determines the reliability and security of unlocking performance. Compared with traditional unlocking methods such as keys, magnetic cards, and passwords, biometric unlocking does not require any tools or memorized information and can be truly intelligent. At present, biometric technology includes fingerprint, face, finger vein, and iris technology.
Face recognition locks has become a new trend in the development of smart door locks With the rapid development of the smart door lock industry, fingerprint locks are faced with low recognition rates and the inability to free hands, and face recognition technology has emerged. In 2020, under the catalysis of the epidemic, non-contact biometric products represented by face recognition will be further promoted.
At the technical level, face recognition technology is changing from 2D to 3D. In the initial stage of face recognition smart door locks being put into the market, most of the products used 2D face recognition technology. Since 2020, smart door lock manufacturers have turned to another thermal imaging face recognition technology, namely 3D face recognition technology. This technology mainly generates and analyzes facial images by analyzing the thermal radiation generated by facial blood, which is unique to individuals and is not easy to cover and forge through makeup.
In the future, with the implementation of face recognition technical specifications and the reduction of the cost of face recognition modules, face recognition will become one of the mainstream recognition methods for smart door locks.
