Storyline: Chinese high-tech companies debuted in the African market at a security expo held in South Africa, providing new solutions to tackle the high crime rate and cybersecurity threats. From Tuesday to Thursday, the 2025 International Securex Expo was held in Johannesburg, South Africa. Nearly ten Chinese high-tech companies were grouped to present new security products at this largest and most comprehensive expo on security products and services in Africa. The Chinese companies have brought world-leading technologies and cost-effective solutions to counter criminal acts in South Africa, according to Mark Anderson, Program Director of the expo. Among all exhibits, a highlight is the rapid fingerprint and palm print matching systems, which can process 100 million matches in one to two seconds, empowering security checks for customs and major events, and allowing instant identity verification. In terms of forensic technology, a rapid DNA profiler dramatically compresses processing time from three to five days to just two hours, significantly extending the golden hour for criminal investigations. For maritime safety, an AI-powered unmanned rescue boat drew particular attention. With visual algorithms, the vessel autonomously identifies drowning victims and deploys flotation devices. Already proven effective in Southeast Asian waters, the technology shows strong potential to enhance water safety for South Africa's extensive coastline.
