Amazon hopes to track your sleep habits with radar (bloomberg.com)

So google and amazon will be scanning our houses with radar

If you stood outside hq scanning them with radar they'd be cool with it right?

I could imagine the fallout if I did this to my neighbors. Legal or not there would likely be pitchforks and worse headed my way. I suppose this is an interesting test to see what people will put up with.

What's the range on this thing? I live in an apartment, so if one of my neighbors in my building uses one of these, will it see my movements, too? If so, how could I defend against that?
