> A device that shines enough energy to illuminate through a wall should not be too hard to detect. As Peter said, that's not a problem if we are trying to locate people in burning building. But if a company sells that as a magic weapon, I expect another company to sell the alarm device, so whoever is attacked gets an early warning.
Meh.  WiFi routers provide this kind of functionality - you're installing the "bug" yourself, or if you aren't, your neighbors may be doing it for you.  There's a whole bunch of research on this - the technique was shown to work at least 6 years ago but it keeps getting better as more powerful ML gets applied to understanding the signals.  One example paper:  https://www.ri.cmu.edu/app/uploads/2019/09/Person_in_WiFi_ICCV2019.pdf
