Wi-Fi Sensing: Your Smart Home Can Track You Without Cameras

You covered your laptop camera with tape. You bought a no-subscription camera that stores everything locally. You disabled your smart speaker's mic. You thought you were ahead of the game. None of that matters anymore. The biggest surveillance threat in your home isn't a camera or a microphone — it's the Wi-Fi signal passing through your walls right now. ADT just spent $170 million acquiring Origin Wireless to prove that your router can track exactly where you are in your house, which room you're in, whether you're sitting or standing, and possibly even how fast you're breathing. No cameras. No microphones. Just Wi-Fi signals bouncing off your body. Your Wi-Fi Already Knows Where You're Standing Every Wi-Fi router emits signals that bounce off your body, furniture, and walls.
