WiFi routers can see people through walls. Here's how it works
www.zmescience.comWith the help of AI, the researchers were able to detect the movement of human bodies in a room using Wi-Fi routers -- even through walls.
What do you guys think about this?

A place to discuss privacy and freedom in the digital world.
Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.
Some Rules
- Posting a link to a website containing tracking isn’t great, if contents of the website are behind a paywall maybe copy them into the post
- Don’t promote proprietary software
- Try to keep things on topic
- If you have a question, please try searching for previous discussions, maybe it has already been answered
- Reposts are fine, but should have at least a couple of weeks in between so that the post can reach a new audience

Privacy stuff aside what do you think the use case gonna be?
Motion tracking without the suit and stuff so we can get easier time capturing motion of an animal for cgi and game.
Security system for cctv blind spot
Batman’s sonar glasses.
There is a lot of other fun stuff you can do with RF, some people even found a way to spy on keystrokes by sending microwaves at an unmodified PS/2 keyboard cable.
How about USB? I haven’t used PS/2 for a long while.
Okay FINE I’ll guess I’ll have to just wire my whole house with Ethernet.
Openwrt exists
Thats a good idea.
Yes. Last summer I sold Residential Fiberoptic Internet access. One of the main selling points was the “wireless mesh system”. It was 3-6 pods placed inside of your home and an optional phone app. The system could be set up and enabled to tell you if there was movement when no person living there was home.
The manufacturer was Plume.
How long until people are “randomly” shot inside their houses?
The fact they’re able to do this is no surprise to me. The fact they’re able to do this on very easily accessible equipment to that degree of accuracy is scary impressive.
While this obviously has huge consequences for privacy, the part that concerns me most is its usage in development of deep fakes. I worry about the consequences of no longer being able to distinguish real video evidence from deliberate manipulation.
Imagine Amazon or Google working out which devices in your home are static, then using them to map out your household with their built in wifi.
Yes I am worried about that too , but what we can do about it? The more I think about this the less I feel the power to do something against surveillance and what it get into my nerve the most is that the big majority of people just dont care that every day we are losing privacy and our freedom. Just look at the UK trying to pass a bill to have backdoor on encrypted communications.
I guess you could design every room as its own faraday cage with separate access points against this specific threat.
Honestly, I’m not sure. Privacy has always been a spectrum, but we’re now living in a world where it’s near impossible to get close to 100% privacy for any action from the start. I suspect the current possible remedies are “ensuring the people and organisations which use/abuse surveillance are heavily regulated and compliance heavily enforced” which ironically requires transparency.
Realistically there needs to be lengthy legal procedures to grant authorities and companies use of such techniques. Legislation like that is complicated and slow to develop though. It also risks pinning the core privacy concepts to specific versions of specific tech, which complicates its enforcement over time.
Even if it is very illegal to do this to someone though, there will always be people who use it for whatever purposes. Obviously making it illegal under wiretapping laws without explicit opt-in consent to do it is something that would need to happen. I’d also like to see mandatory source attribution laws.
That won’t stop everyone though. Which means we maybe need to start looking into comstruction legislation to ensure RF blocking materials are used in external wall construction. If that is an effective remedy to Van Eck phreaking at all. I have no idea what resolution information can be determined from devices that aren’t purpose built broadcasting and receiving devices.
And all of that requires good-will and sensible decisions from the existing legal systems and legislators. Which can’t be completely achieved, and in many cases is… currently very poor.
Tl;dr A very hard problem which will need work from a bunch of different parts of society and likely cannot be completely solved for all people. The only solution for this specific technique right now I think is to go fully off-grid with no electricity. Even then though you’ll still have satellites and drones to intrude.
@randomguy2323 @privacy It’s only a gimmick, for now. Notice they had to use multiple access points and receivers and calibrate the system based on the room it was in.
Typo in the article - “found inn”
Wasn’t that a known thing already? I mean humans are a moving interference and partially reflect the microwaves, so its kinda obvious that its technically possible to do that… That would btw likely work with Radio waves as well, probably harder however, because they cover more area and therefore have more background noise.
I think the main difference is how ubiquitous these wifi signals are and the fact that the signal is very homogeneous, allowing for the ai patterns to work on a large scale.
Yeah - in article, it reads the resolution of data is significantly higher.
I hate it
Great, now I have to cover my walls in tin foil like that guy from Better Call Saul.
a) well that’s fucking terrifying
b) did they really end that with an ad for baby cameras? Or was that a blank ad fill-in-the-blank thing?
I got the same ads, so I’m assuming it’s related to the content.
Well at least it’s not an AI saying it’s a boy I guess
There’s actually a lot of crazy shit you can do with EMF.
Look up Van Eck Phreaking. The theory was developed on CRT monitors but can be used on LCD as well where you use the monitor as a listening device.

Haha theremin go eeeeeeeeeeeeee
Really interesting I will take a look at it
AHHHHHHHHHHHHHHHHHHHH I can’t live in peace can I
There is no privacy anywhere
That’s very creepy
So, no privacy? Now we need rooms with build in faraday cages which make it even more suspicious.
