00:00Scientists are using AI to hack Wi-Fi routers to see you in your home like a camera.

00:05So what they did is they had, you know, a camera looking at a space with people in it.

00:11That's sort of like coming in from one eye.

00:12The other eye is the radio signals, so sonar from the Wi-Fi router.

00:17And they just learned to predict, like, this is where the human beings are.

00:21Then they took away the camera.

00:23So all the AI had was the language of radio signals bouncing around a room.

00:27And this is what they're able to reconstruct.

00:31Real-time 3D pose estimation, right?

00:35So suddenly, AI has turned every Wi-Fi router into a camera that can work in the dark,

00:42specially tuned for tracking living beings.

00:45No real cameras, no microphones required.

00:48Just the invisible waves bouncing around your house right now,

00:51watching you breathe, move, and even sleep.

00:54And the scariest part? You wouldn't even know it's happening.

00:57Wi-Fi routers don't just send out internet.

00:59They send out radio waves that bounce off everything in your house.

01:03Your walls, furniture, your own body.

01:06Every time you move, even just slightly, those waves change.

01:11They bend, scatter, and reflect differently.

01:14And now, AI can read that change and that chaos like a book.

01:18Thanks to breakthroughs in machine learning, scientists have trained models to analyze these patterns

01:24and reconstruct your physical movement, your position, your posture, using nothing but Wi-Fi data.

01:32This isn't a conspiracy theory.

01:34This is peer-reviewed science.

01:36MIT created a system called RF-POSE, which can track people through walls.

01:42Carnegie Mellon University used two off-the-shelf routers to create silhouette images of people moving in a room.

01:50Other researchers show this can be done with an almost 100% accuracy.

01:54Again, no camera needed, just your Wi-Fi.

01:58This is the kind of thing that just decades ago was military-grade.

02:02Now, it's just software and some smart routers.

02:05Of course, publicly, the narrative is a little different.

02:08Researchers say that this tech could be used for elderly care, detecting falls or health emergencies,

02:14which it could be, to be fair.

02:16Sleep monitoring, tracking breathing patterns or movement, both of which it can do.

02:20And security systems, spotting intruders even if the cameras are off.

02:25But here's the big catch with this.

02:27You wouldn't know it's happening.

02:29And that's where things get dicey.

02:31This tech doesn't need your permission.

02:33It doesn't need a camera lens or a microphone, just a Wi-Fi signal and someone with the right software.

02:39Imagine a world where your landlord can track when you're home,

02:43or a hacker can watch your movements through your own walls.

02:46Or worse, governments use it for passive surveillance, saying,

02:50Hey, we didn't record anything.

02:52We know that's not far off.

02:54In fact, patents from big tech companies have already hinted at using Wi-Fi for non-contact monitoring and surveillance programs.

03:04They love anything that leaves no trace.

03:06And if they're patenting it, you know they plan on using it.

03:09So how do you stop it?

03:11Honestly, you can't.

03:12Not easily.

03:13The only way would be to completely shut off your Wi-Fi or wrap your house in a Faraday cage.

03:19And let's be real, that's not happening.

03:21We're heading into a future where every signal is a sensor.

03:25Where your internet doesn't connect you, it watches you.

03:28This is the kind of tech that changes the rules.

03:31It blurs the line between convenience and control.

03:34Between connection and surveillance.

03:36So what will you do?

03:38Switch off the internet?

03:40Go dark?

03:40Or just allow this to happen?
