Couldn't I also rig up a device like this to determine if someone was in their house from the outside? or if I'm in an apartment building... all of my neighbors

- Bartweiss 9y agoAura apparently detects between a base station and a sensor on opposite sides of the house. So it sounds like you could use exactly this, set up outside, to determine whether anyone is moving around in a home.
- willvarfar 9y agoyour local swat team is probably equipped with "wall penetrating radar" which they use to assess the situation before entering a building. There are acoustic versions and they also thread fiber optic cameras under your door, so passive systems that image a building from the emissions in the building are probably something they'd buy too.
