Best Security & Surveillance Technology Companies in China
The 371 best Security & Surveillance Technology companies in China in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Megvii.
China's Security & Surveillance Technology sector is one of the most heavily capitalized corners of the global industry right now, and this directory ranks the companies building it, ordered by disclosed equity funding and recent momentum. We're tracking 371 firms with a combined $7.2B in disclosed funding, five unicorns among them.
The numbers tell you where the weight sits. Megvii leads at $2.0B raised, followed by Hive Box at $1.1B and Dahua Technology at $741B, with Black Sesame Technologies adding $500M. That's a concentrated top tier. The global security and surveillance market sat at $284.7B in 2022, growing at 4.8% CAGR, driven by government mandates and the integration of physical security with networked surveillance hardware. Privacy concerns are a structural friction point, but so far they've slowed product design more than deal flow. Across the broader security and technology app ecosystem, as shown in this recent sector recap, median install growth is running around 15% year-over-year. So the consumer appetite is clearly there. Investors like SAIF Partners, Tencent and Shunwei Capital keep showing up across rounds, which tells you this isn't a one-cycle story.
