Dahua Selling Protestor / Banner Alarms, Deletes Evidence
Political protests are quickly suppressed in the PRC, most famously with the recent Beijing Bridge Man banner. Dahua is offering a technological solution to this with AI analytics that automatically detect and report protest signs and protestors' faces to PRC police.
IPVM also found Infinova lists cameras with this kind of analytics. IPVM is the first to report on the existence of this type of solution.
Dahua deleted all evidence shortly after IPVM reached out. For more on PRC alarms on protestors, journalists, and religious/ethnic minorities, see:

Neither Dahua nor Infinova responded to comment requests.
