As Robert Heinlein once said:
"The police of a state should never be stronger or better armed than the citizenry. An armed citizenry, willing to fight, is the foundation of civil freedom."

A cheap and easy way to defeat night vision cameras filming either from a helicopter or drone
This is what every patriot needs to know.

I'd be careful putting my life on the line using this tarp.
ReplyDeleteI know the systems I used could see the breath of person coming out from under a car...
Now it might hide your form for a few minutes, but not for long.
Aat best after a few minutes you'd be a less distinct heat source/shape.
YMMV, if you wanna think this will hide you, then do so.
Better than nothing when the BLM boys come looking for you. Any suggestions on how to do it better?
DeleteSeveral thermal tarps, separated by at least 4"... more if the air is still.
ReplyDeleteBreathe into something that will cool your breath before expelling it outside. Like a jug full of rocks with slots cut to let the air out after the rocks absorb heat.
This will work for a short while.
THe longer you are under the tarps, the more likely you will be seen.....better to stay under more mass...like in a cave or under feet of dirt. and still then you gotta get rid of the heat. People put out a fair amount of heat, and it is easily detectable with the right equipment.
Now, I gotta say this. In warm weather (80+) your signature under the thermal tarp is gonna be small. You can hide for a while. FLIR and other thermal imaging sees better at night or when it is cool. The greater the difference between you and the background, the easier it is to see you.
SO this system will work in warm summer days, and hot summer nights in Texas or AZ. For a while at least, until things cool off.
Excellent, thanks for the help!
DeleteLet us not confuse "Night Vision" with Thermal/FLIR. The former works by means of a charged device that accelerates photons across a charged gap to strike a screen creating many more photons. Essentially it multiplies the number of light photons electronically. 3rd generation stuff works quite well. The same things that make it hard to identify someone in daylight work at night with NV.....i.e. camo clothing works.
ReplyDeleteThermal/FLIR is a different animal. It measures the difference in temperatures of objects...and modern stuff has a discretion of about .2 degrees. While the setup shown using the mylar blanket and poncho is relatively effective one must maintain an air gap between the body....the source of heat and the screening material. If an operator of such a device knows a person is
in a specific area there is a good chance that given time they WILL find them. However if the operator is merely screening to see what's out there they can easily overlook someone using the various methods of screening heat signatures. You simply cannot fool the equipment...it faithfully presents any and ALL temperature differences. However you CAN fool the operator who is the one that deciphers the image and to determine if what they are seeing is or is not important.
Ambient temperature is the biggest factor.....if it's cold and you are hot your body puts more
heat out....a "bloom" becomes apparent and triggers further investigation. If it's warm the heat from your body causes less change in the surrounding environment making it harder to find you.
The method described will likely be far more effective in the summer than in winter.
