Funny my professor was talking about this years ago. Not the article but how WiFi could he used like an X-ray to see things since we use WiFi everywhere .

>use it to “see through walls,” or, rather, approximate the location of devices via sneaky scanning.

I have an "invisibility cloak", or rather, a sign that says don't look at me

Yeah, those parts alone are less than $20, so it probably includes expedited shipping.

No. It will be able to see which devices are connected, not where in the house those devices are. The concept from the article has multiple radios, and can therefore do triangulation of the received signals.

I suspect the writer misunderstood, and the cost is for the custom electronics attached to it. That will add up to about that much (less if you import straight from China). Those ESP boards are dirt cheap and quite versatile.

What is the name of the $20 drone?

Maybe, if they were able to. For what it is I think that could be difficult though.

>they could not use this without a warrant.

You mean that they would use parallel construction after knowing what they know after using it, and wouldn't tell you they used it. You wouldn't know they used it.

Absolutely not. GCHQ does the same stuff the NSA does, but your overt surveillance (CCTV and the like) is significantly more than the US has. I think they probably like that the US gets all the publicity though.

In the US the cops have to ask private citizens for CCTV footage much of the time. Ring kind of let them in without doing that, but it is still a private entity.

It’s about criminal charges, they could not use this without a warrant. Mass surveillance is something else, the government will do what the government wants to do.

The cited case was regarding a person suspected of a marijuana grow. The police used thermal imaging without a warrant to get a conviction. The Supreme Court determined it was considered a search by the fourth amendment (5-4 decision, btw). That would be similar here.

how do you-

Na I always thought the usa was more then a surveillance society the us

Yeah, MKultra was also illegal. Still happened lol.

You mean you want me to facilitate you taking control of everybody’s phone in the city? I won’t do it

Consider this:

To use a 32" 4k monitor, you need to place it at the same distance as a notebook, so you can see it just like you see a 16" 1080p screen (you wouldn't push that screen farther away).

Now if you replace that screen with a 65" 8k, you'd need to keep that distance, and you'd end up with a ginourmous screen very close to your face. I just went close to my 65" TV and it doesn't make sense.

Either you place the screen close and your eyes get tired from movement, or you place a larger screen farther away and get tired from focusing on distance.

"20$ off the shelf drone"

shows 500$ dji camera drone

Wi-Fi device positioning is incredibly old. Students at my university used a similar technique for triangulating people. Using a drone though is interesting as it can quickly fly around getting a lot of measurements at specific locations.

The pixel density on a 65" 8K screen is the same as a 32" 4K screen. Just treat it like a dual (or quad) monitor setup without any bezels in between.

Good points

Wasn't there something revealed recently that used wi-fi to literally view PEOPLE (not devices) through walls?

Edit: Video link is here.

Anyone who can receive the signal from your router can see through the walls. Your router doesn't know where you are in your house.

The article probably answers your questions if you care to click it.

I imagine that there might be a desire to see trough walls that are taller than what a handheld device would be capable of reaching…like if you had to see through the walls of the 40th floor of a building from the ground. Aside, this thing is horrific and doesn’t need to be made. We need privacy laws.

Why is it a drone?

Okay so anyone hacked into my router (government etc) can use the router to do the exact same thing right?

Only after the government gets caught doing it and only if any of the corrupt system actaually holds them accountable. Which is unlikely at best.
