OVER 20,000 new technologies and products from more than 1,100 companies from around the world were showcased at the 20th China International Public Safety Expo (CPSE), which concluded Thursday at the Shenzhen Convention and Exhibition Center in Futian District.

Attracting registered participants from over 150 countries and regions, the four-day expo featured an international buyer lounge to facilitate global business matchmaking, bringing together government agencies, industry purchasers, and digital-city project representatives from more than 100 countries.

Procurement needs spanned multiple sectors, including low-altitude security, emergency management, smart governance, intelligent transportation, and smart energy, highlighting China’s advanced digital security solutions and implementation experience.

Tianjin Yunxiang UAV Technology Co. Ltd., a leading Chinese manufacturer of drone countermeasure systems, showcased its latest product lineup featuring both passive and active UAV detection terminals, jamming and spoofing countermeasures, and advanced time-signal protection systems.

“Our latest time-signal protection system leads the industry in key performance indicators and is fully protected by proprietary intellectual property,” said Chen Ling, general manager of Yunxiang. “It effectively counters malicious attacks and biased data, completely isolates spoofing signals, and maintains a high-precision time benchmark.”

Accordng to Chen, the company’s products are widely deployed across nearly 30 provincial-level regions in power facilities operated by State Grid Corp. of China, China Southern Power Grid, and other major energy companies, playing a crucial role in safeguarding national energy security.

Running parallel to the main exhibition, the 3rd Digital City World Congress focused on cutting-edge technologies, including artificial intelligence, 5G, computing power, IoT, big data, machine vision, large models, intelligent systems, and low-altitude safety. The congress featured more than 100 specialized forums and exchange sessions.

Launched in 1989, the CPSE has grown into the world’s largest and most influential security industry event.

The boom in China’s low-altitude economy comes with growing security risks, such as cyber attacks and data leaks. Unregulated drones pose a particular threat — their small size and low operational altitude make them difficult to track, while their high-resolution cameras enable covert surveillance, raising serious safety and cybersecurity concerns in crowded and sensitive areas, as noted by the Ministry of State Security.
