Given that EM serves as a lense into our homes, would this provide an effective counter measure??

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.
If you make a room’s walls and ceiling/floor electrically conductive (with paint or tin foil or wire mesh), you create a faraday cage. And as long as the gaps are small enough (proportional to the wavelength of the signal you want to block), nothing in those frequencies is getting in or out. A Faraday bag for your phone might be cheaper, though.
Absolutely, chicken wire in the walls (if property set up) will do a lot. My point was that I have never run into rigorous third party testing around the paint, so the marketing may make it sound far better than it actually is.
I can tell you it does work. I’m working in a lab painted with such stuff. No, we are not doing anything nefarious, but we had developments stints into wireless and radio technology, and having a properly shielded room to work in helps avoiding trouble with the neighbors. I don’t think they would appreciate getting their wifi jammed when someone here is trying to find a bug in a sender or something like this…
Cool. Are you using anything beyond paint (mesh in the walls or something)? Also, what brand of paint?
It definitely seems like something that should be able to work (to some degree), but also something that it would be pretty easy to scam.
No idea what exactly was used. This was done when they built the building, way before my time in the company.
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.
I don’t know if that’s true. There is always a fair bit of conductive stuff in walls (wires, pipes, etc) that these sorts of systems already need to be able to handle in order to be interesting. The paints feel like they could easily be snake oil.
If OP really wants to do something about this, grounded chicken wire mesh should do the job, but that’s a lot more work.
True… I really don’t know enough to know how twitchy þey are.
Why so thorny?
