The rapid development of new technologies such as the Internet of Things and AI has driven the intelligent door lock industry to undergo technological changes from key unlocking to password unlocking, and then to fingerprint recognition, facial recognition, and biometric recognition. At the same time, the entry of more players has also accelerated industry technological innovation and experience upgrading, promoting the development of smart door locks towards a safer, more convenient, and smarter direction. On April 17th, domestic intelligent door lock head enterprise Deshman released four breakthrough technologies: iris recognition, WeChat audio and video call, AI voice registration, and SHOTAX Sentinel cat eye system. At the same time, it launched products equipped with relevant technologies such as AI iris intelligent lock K10, floating intelligent control lock K77, cat eye large screen intelligent lock Q5MPro, and cat eye rear screen intelligent lock Q3MPro. Among them, iris recognition technology is particularly concerned by the industry. It is understood that traditional iris recognition technology has always faced two major challenges: firstly, the effective recognition distance range of traditional iris technology is narrow and inconvenient to use; Secondly, the recognition height is narrow, and the human eye needs to be aligned with the camera's orientation. These technical difficulties have led to traditional iris recognition falling far short of consumer demand. Deshmann stated that through the innovation of optical lens technology, Deshmann has broken through the effective recognition distance limit of iris recognition technology and expanded the effective recognition range by four times. In addition, Deshmann has innovated the iris self tracking recognition system, which can quickly and effectively lock the height position, achieve automatic lens homing, and then use autofocus technology to lock and recognize the iris. Coincidentally, on the same day, Huawei also introduced a new and upgraded intelligent door lock product, and launched functions such as message reminders, safety reminders for elderly people living alone, and reminders for children returning home. Like Deshman, in addition to ease of use, safety has become a repeatedly emphasized focus of Huawei's smart door locks. Huawei stated that its smart door locks provide security protection from both hardware and software levels. In terms of hardware, Huawei's smart door locks adopt C-level lock cylinders and use technical protection measures such as anti cat eye unlocking and anti violent damage, which can effectively prevent illegal elements from infringing on family safety; In terms of software, Huawei's intelligent door locks are equipped with functions such as security alarms and AI monitoring snapshots. When someone hovers outside the door, abnormal situations can be detected in a timely manner and corresponding measures can be taken. The market penetration continues to expand. According to the Summary Report on the 2022 Online Market of China's Household Smart Door Locks released by AVC, the total sales volume of China's household smart door lock market through all channels in 2022 will be 18.05 million sets, of which the online market will account for about 32%, with the scale of 5.378 million sets, up 17.4% year on year. Ovi Cloud Network predicts that in 2023, the omnichannel sales of Chinese household smart door locks will reach 19.6 million units, an increase of 8.6% year-on-year. Among them, the online market is expected to sell 6.17 million units, an increase of 14.7% year-on-year. According to the "2022 China Smart Home and Smart Door Lock Industry Research Report" released by renowned consulting firm Frost Sullivan in April this year, the Chinese smart door lock market is in a stage of explosive growth, and the overall market size is expected to exceed 40 billion yuan in the next five years. Faced with such a huge market for growth, many brands are competing
