RE: How to see an enemy if they breach your area.
I don't understand how they can work as described. IR is on a different wavelength that we can't see. The filters simply filter out some light allowing only certain wavelengths through. So, I guess, that IR would get through but we still can't see it so how does that work.
I'd guess this just allows red light through so we see a red torch not IR.
Anyone tried this? If you do let me know how it goes.
