"It’s developing a service code-named “Viper” to parse data from thousands of live camera feeds ... The ultimate goal is to juggle 100,000 feeds simultaneously." Technically, this sounds very ambitious. Assume a 24/7 video feed is several gigabytes a day, meaning at 100,000 streams they'd be processing several hundred terabytes a day. Furthermore, as a conservative estimate, assume face detection is run once per second, half the day (maybe they shut it off when nothing interesting is detected), that's over 40K frames / day to analyze. So 4B images / day total. AWS charges about $60k / 1M images with face detection only, that's $2.4M per day. I'm sure SenseTime's costs are lower than what AWS charges, but that's still some serious computing power. Their customers (presumably Chinese government) must have really well lined pockets to make this sustainable.
