Smart door locks have experienced rapid growth since 2016, driven by their ability to offer convenience to users while improving operational efficiency for property managers. According to the "2017-2020 China Smart Door Lock Technology and Application Market Analysis Report" released by Siruida Consulting, the market size of smart door locks—those equipped with biometric identification or network connectivity—reached nearly 8 million units in 2017. It is projected to exceed 60 million by 2020, with an annual growth rate surpassing 100%.
Fingerprint recognition has become a standard feature in home security applications. Market research conducted by the Smart Product Circle revealed that in the apartment rental sector, especially for short-term rentals, law enforcement agencies have been promoting the use of fingerprint locks. These devices help manage the mobile population by accurately identifying individuals, aiding in the fight against crimes such as fugitives, drug abuse, and gambling.
For instance, a well-known short-term rental platform was recently fined 40 million yuan by public security authorities for related incidents. As a result, property operators are increasingly motivated to install fingerprint locks on rented properties to avoid legal liabilities stemming from unverified tenant identities. This trend further highlights the growing demand for secure and reliable identification solutions.
The rise of smart door locks presents a significant opportunity for fingerprint recognition technology. While smartphones have popularized this technology among consumers, the mobile phone market is now saturated. Companies are now seeking new markets, and smart door locks represent one of the most promising areas.
However, it's important to note that fingerprint recognition is not one-size-fits-all. Different application scenarios require distinct technical approaches. For example, the parameters used in smartphone fingerprint systems are optimized for speed and convenience, but these settings may not be suitable for high-security environments like smart door locks.
Experts emphasize that the security requirements for smart door locks are far more stringent than those for consumer electronics. The system must ensure life safety, which means higher standards for accuracy, reliability, and resistance to attacks.
At the recent "Safety Fingerprint Life" technical seminar hosted by Suzhou Mindray Microelectronics Co., Ltd. in Shenzhen, industry leaders from public security, academia, and technology sectors gathered to discuss the future of fingerprint identification in IoT security. Topics included the security challenges of fingerprint systems, the evolution of core technologies, and real-world applications.
Li Yangyuan, founder of the "texture phase" fingerprint recognition algorithm and inventor of the CQT capacitive sensor technology, emphasized the importance of security, quality, and precision in fingerprint solutions for critical applications. He stressed the need for factual discussions rather than marketing gimmicks.
As the smart door lock market continues to expand, the demand for robust and secure fingerprint solutions will only grow. With ongoing advancements in technology and increased awareness of security risks, the industry is poised for continued innovation and development.
