At first i was skeptical but when i read the and realized it uses A.I. to interpret radio waves i realized it was certainly possible.

This is obviously more for show but its a cool development nonetheless. articlehttps://www.nbcnews.com/mach/science/smart-technology-sees-through-walls-track-identify-people-ncna888721
