I have a stealth startup that designs privacy first solutions to share coarse data about what is inside of rooms without disclosing secrets. This is useful for many use cases, from detecting the number of people in a room to other motion sensing devices which are critical for health and human safety. Patents are pending.

That's great! It does feel like cameras generally collect more data than necessary for some purposes. I have a friend who works at Butlr, which uses thermal sensors to detect body heat (and avoid the privacy risks of cameras) - sounds like your startup is in a similar space.

I know you mentioned patents pending, but is there anything you can share about your approach?

"Room occupancy sensors" are a common product. Butlr apparently uses a low-rez IR camera, although they avoid calling it that. Passive infrared is common. Millimeter wave is available.[1]
