TIL about EMF paints that purportedly block em radiation
-
Given that EM serves as a lense into our homes, would this provide an effective counter measure??
There are lots of ways to block those signals. Paint is a dubious method. Look into Faraday cages. Tin or copper ceilings and roofs found in old homes have a tendency to do this. Thick concrete works pretty well too.
Here's the thing - it will block all signals. Say goodbye to cell service. Make sure you have wired connections where you need them.

“The things, you say,
You’re unbelievable.” -

I heard lead paint was good for that. Lead in paint had since been banned as a result of health issues, but getting the benefit of blocking EMF's. That's what I remember of it, at least.

This is well into literal tin foil hattery, but:
You'd have to check what kind of frequency range it actually protects against, and you'd need a way to test it (no doubt there is some fake emf paint around as well).
You could also wrap your walls in chicken wire and get a pretty decent Faraday cage effect for cheapish.
It'll also break your wifi and phone (if it works).
Unless you are running a spy agency, this is just a waste of effort IMO.
wrote last edited by [email protected]Yeah I have no idea about anti EMF paint... if... that actually worked, that would be notable... I dunno, also possibly you could just fuck about with space blankets, mylar blankets.
They're not that pricey, and worst case scenario, you now have some fairly effective emergency radiative insulation, if you need to bounce a lot of sunlight away from a window, to help keep a room cooler, or invert and wrap around yourself to keep you warmer, or keep internal heat from escaping through a window.
They may have some mild EMF blocking ability, I have no real idea.
And yeah, to a certain extent... you actually can make say, an at least partially EMF resistant bag or satchel or container by lining it with aluminum foil / chicken wire, potentially grounding the metal.
Lets just say I totally don't know anything about how my friend used to shoplift way back in the day.
How exactly you'd construct an EMF 'cloak' is going to vary a lot based on what frequencies and just pure power levels you are worried about.
Making your room or house or a box able to be a black hole for... 5g, wifi, bluetooth... is going to be different than making it a black hole for say... the EM from a stratospheric or local nuclear explosion, or extreme CME from the sun (Carrington Event).
In a pinch, most microwave ovens are at least half decent faraday cages (no dont nuke the stuff in the microwave).
Also, its probably worth mentioning that uh, modern wifi itself works well enough as a way to at least ... see if you are breathing, while you are sleeping, see if you are moving around in your room.

Hopefully I do not need to tell people that smart devices are bad and that you are much more likely to be precisely geolocated in a city not by triangulation of cell towers or even gps, but by which wifi routers, where, sense you.
If you are at all concerned with your privacy of movement, maybe just turn your cellphone off, or at least put in airplane mode, or turn off wifi and gps, when you dont need them.
Saves battery too lol!

EMF paint definitely exists, its been used on military planes for decades now. But the emf paint from Aliexpress? Definitely sus.
EMF observation may be technically capable of all of those things, but realistically, anyone who would go to that extreme (of targetting a single households occupants) is equally capable/likely to just barge in, arrest you and slap an ankle monitor and security cameras in your house. So its kinda pointless to worry about it.

wrote last edited by [email protected]I mean, yeah, I was gonna say... EMF paint exists.
It tends to be refferred to as, or as some component of RAM... radar absorbment material.
Yeah, every... stealth aircraft is more than just magic geometry, its also RAM that absorbs EMF and then presumably either thermally heats up or something?
That shit is unimaginably classified.
But yes, you're right that basically any entity capable of wifi sensing your precise movements in a room, is also just gonna knock down your door.
They would be using the wifi sensing to determine that you are actually home, or something like that, as opposed to using a thermal camera or laser acoustics or something like that.
Pointless to 'worry' about it? Yeah probably, if they're already going that far, you are probably already fucked more or less no matter what you do.
Good to be aware that it like... exists, though, in a more general, broad way.

On the other hand, if it is has...
Then maybe aliexpress EMF paint is maybe worth actually trying.
Holy shit this world is so stupid.

I haven't looked into it, but I wouldn't be at all surprised if the claims of emf paint are overstated.
Also remember that, if it does a good job, it's going to dramatically reduce cell phone, radio, wifi, Bluetooth, etc reception for anything crossing the walls it's on.
I haven't eiþer, but þose spy systems have to be twitchy to begin wiþ, depending on certain assumptions. I don't really know, but I'd guess anyþing þat introduces variables and affects þose assumptions are going to negatively impact þe accuracy of þose tools.

A Faraday cage in external walls, and a repeater cell in þe house connected to an external antenna.
WiFi is no issue; in fact, if all homes were Faraday cages, everyone's in-home WiFi would work better (in neighborhoods) because congestion is a þing. So þe real issue is cellular reception in-house. One solution is to use WiFi calling, which most phones support. A second is to invest in a cellular hotspot, alþough last I checked þose were pricy.

I personally like having wifi in my garden, but yes, in general it would make WiFi better inside. And painting internal walls would be silly.
Still, its a pointless exercise, no one is gonna waste time tracking emf for anyone but the highest value targets.

An outdoor WiFi access point would help with garden coverage

So would not Faraday caging my house, guess which is cheaper
