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’.

    The paper was link week or month ago but this need a lot of train data to even recognize room let alone person. Possible but not feasible.

      That data exists in abundance and it’s even available for purchase in small (consumer) or massive (corp) lots.

      Possible but not feasible.

      Inaccurate, but I can dig the hope behind it.

        Wifi timing signal capture in your room? In order to pull off you need train on room you want spy on. Which require almost constant physical access to measure. In which time you plant spy cam and not need this tech.

        Edit: remember wrong, not need physical access, but need in range. not able to place spy cam but still much easier way if already in wifi range.

          I believe you’re conflating the goal of isolating humanoid masses inside a structure with mapping of the interior space. Please, do your own research. It won’t take you very long to discover that the former has been in use for decades already, in both military and municipal capacities. I’m not here to argue opinions or feelings, and would welcome citations for your stance. 🖖🏼

            Researchers say these signal reflections can effectively create multiple “views” of a person, allowing AI systems to learn and recognize individual identities.

            After the machine learning model has been trained, identifying a person reportedly takes only a few seconds.

            Original article: https://www.kit.edu/kit/english/pi_2025_069_the-spy-who-came-in-from-the-wifi-beware-of-radio-network-surveillance.php

            It works by exploiting the communication of legitimate users of the WLAN, whose devices are connected to the WiFi network. These regularly send feedback signals within the network, also called beamforming feedback information (BFI), to the router – in unencrypted form so that it is readable by anybody in range. This creates images from different perspectives that can serve to identify the respective persons. Once the underlying machine-learning model has been trained, the identification only takes a few seconds.

                Only the one abour spy cam, as i say in edit. But this data not available and need special ai training to identify for each router.

                  Ah, I see you’re thinking like a researcher and not as an oppressor, fellow anon.

                  The former focuses on evidence-supported results, and rightfully so, whereas the latter barely aims at a hint of the flimsiest legal precedence in “identifying” individuals before “confirming” they’re “terrorists”.

                  In short, the implied argument that positive ID of a target individual within said structure is paramount for a kill order is irresponsibly naive, but I hear the hope that fuels it.

                  Untold numbers of innocents are slaughtered every single year in gov’t sanctioned events based on intel that was half-assed/hurried/redacted (or deliberately poisoned), and we’re generally only seeing the ones that the “police” murder without consequence. (Though, with the advent of televising military actions via “news” programming, we can now see those bootlickers murder civilians w/ barely an “oopsie”, too.)

                  No. This tech is already more than functional for their needs, and has been for at least a generation now, if not longer.

                  If anyone reading this is still on the fence, I suggest you take a more critical look at the wording in the reports of said innocents’ deaths.

                  The “wrong place, wrong time” excuse is disgustingly pervasive, and in flagrant (and intentional) disregard for the victims in their own homes, cars, workplace, school, et al. —nevermind the indefensible fact that none of them had anything to do with the stated intent of said police/military activity.

                  To sum up: they’ll “ID” the target, label it hostile, and rush to play Momma’s Favorite Crusader on whomever the lucky innocent is that day. Could be any of us, and statistically will be, if things keep escalating along this arc.

    “theoretically” is doing an enormous amount of heavy lifting here… tracking specific identifiable people in this manner (especially when multiple people are present) is about as close to sci-fi as we can get at this moment in time.

        IMO history isn’t relevant here though because I specifically quantified my statement with “at this moment in time” since I knew I would get a response like this.

          Then your claim that it’s “as close to sci-fi as we can get” is ridiculous, considering we’ve been that “close” for at least a generation —thereby making your “quantifier” useless at best. Maybe, next time you expect a logical response to your illogic, pass on voicing said opinion until you’ve had more time to think on it. 🤷🏼‍♂️

    You don’t justify “Wi-Fi can be used to track your movements”. Sure, it seems plausible that radio waves can be used to detect an individual’s location, but does anyone have the infrastructure, organization, funds, will, and power, to track the generic “you”, the “you” at scale, as implied in the post title?

    Do be careful with your wording.

      Do they? Dunno. “They” have been working hard on exactly this for well over 30yrs now… 🤷🏽‍♂️

      You tell me. Look around at the world right now, and ask yourself: what do they not have unfathomable amounts of data on?

      Yeah, your wifi router can’t track you physically, but a device can be built that can essentially use wifi signals to see through walls.
