Smart door locks showing key potential

"The quality of door locks has a significant impact on the quality of people's lives. If consumers can't easily get into or out of homes, it would be troublesome. Consumers should use high-quality locks to ensure the convenience and safety of daily life," Zhu said.

The company's high-end smart locks have continuously ranked at the very top in sales within the country. Besides, global market research conducted between 2021 and 2023 showed that Desman took the top spot for sales volume and market share in the global high-end smart locks market for three years, Euromonitor International said.

The survey included the Chinese mainland and overseas countries and regions, such as North America, Asia, Europe and Latin America. The survey researched more than 10 brands, including Desman, Samsung and Xiaomi, Euromonitor International said.

"The research and development of smart locks integrate technologies such as artificial intelligence recognition, biometric identification and cloud computing, and the R&D of a product usually requires three to four years. We have invested an increasing amount of funds in R&D year by year," Zhu said.

He added that the latest products can be connected to mobile phones, and even if a fingerprint is worn down, like those of gymnasts, the locks can still recognize certain fingerprints.

The fingerprint module applying the company's GPTfinger fingerprint recognition technology has achieved a false acceptance rate of 0.00099 percent and a false rejection rate of 0.86379 percent, it said.

"GPTfinger fingerprint recognition technology has enabled the products to embrace a new era of GPT algorithm-based recognition, and this advancement addresses the challenges faced by a small group of people with difficulties in fingerprint recognition," said Maksim Kriukov, a certification officer at London-based World Record Certification Agency.

This has also been awarded as the "world's most outstanding smart lock with ultrahigh fingerprint recognition rate" by the agency.

In addition, Desman has completed the building of its fourth global joint laboratory in Phoenix, the United States, thus completing its global network of four labs.

These labs are strategically located in diverse environments, including the desert climate of Phoenix; the extreme high temperatures of Dubai, the United Arab Emirates; the typhoon-prone weather of China's Taiwan province, and the moderate climate of Hangzhou.

"The labs form a comprehensive testing network and enable Desman products to go through rigorous reliability tests in extreme conditions, ensuring long-term stability of the smart lock products across regions," Zhu said.
