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]
