I guess it is good to be aware of what’s possible. But all this stuff about using WiFi to measure things about people—it’s a bit creepy, right? I mean, to state the obvious, we (as a society) have got a bunch of poorly patched or corporate controlled WiFi routers attached to the network. What a surveillance catastrophe waiting to happen.

I mean, heart rate? Do we have a giant network that can tell where everybody is and whether they are having a strong emotional response to anything?

You are not exaggerating to be weirded out by this. It’s already being used to monitor people in their homes by law enforcement.

Your comment should not be gray, as you've stated a rarely known fact. I used to have an old brochure with the exact model number of the device you refer to. And it's been around for well over a decade.

I'll try to find the model to rescue your post. People can be so fucking unreasonable here it makes me sad.

But I know exactly what you're referring to.

Note: it's also worth considering its applications in parallel construction and that it's indeed so rarely known, that it doesn't require a warrant.

Edit II: they were, at one time around 2011 definitely having a lot of fun with these devices in my town here in Florida.

Thank you! I wanted to provide a source, but I have literally only seen it in action at a trade show, and could not remember what it was actually called.
