A post just in case nobody knows about it. This isn’t a conspiracy post, it can be done, the video link is there by Cyb3rMaddy to explain it more thoroughly. It isn’t new tech, it has been around for more than 10 years. It is just crazy to think that somebody can somehow tap into it, maybe your ISP. Who knows how this is being used today. Since there are no cameras on routers, it is unregulated. Your ISP can theoretically use your home Wi-Fi router to track your movements. By analyzing how your body and walls disrupt and reflect wireless signals a technology known as Wi-Fi sensing, AI models can map exactly where you are, what you’re doing, and even your posture. This is wild to think about, I am guessing regular people don’t know this, but it can happen. Since this can be done, somebody can use it against you. It can even detect human breathing rhythm and heart rate. Sitting at home and unaware. Your cell phone can be used as an Wi-Fi access point. Another example is your smart fridge that has Wi-Fi, it does send back data to somewhere anyway. Like when you run out of food or something. I would never get one of those, personally. I totally understand those people that just want to move to a cabin in the woods somewhere.
FWIW, Through-the-Wall surveillance (TWS) was discovered waaaay back. Here’s a few:
1.) (1842) American physicist, Joseph Henry, noticed that the discharge of a Leyden jar in his first-floor laboratory successfully magnetized needles in the basement, passing through two 14-inch-thick ceilings
2.) (1990s) “Through wall sensing addresses the desire to see inside structure to determine the layout of buildings, where occupants may be, and even identify objects within…”
3.) (< 2005) DARPA’s VisiBuilding handheld "…useful during a range of operations—from pre-mission planning to find which buildings should be searched, through post-mission analysis to find hidden objects or people."
4.) (2006) "…the TimeDomain system, which uses ultrawide band radar TWS technology. Because radar currently is blocked by metal walls or aluminum-backed insulation, an acoustic capability would allow the TWS device to provide some surveillance capability to penetrate through those walls.
Etc., etc.
p.s. IIRC, hats made of tinfoil would not only fail to deflect incoming “mind-control” signals, but they’d create sort of a convection oven on your brain by reflecting said waves back down afterward. Just sayin’.
