[@charleschristianson2730]

I spent thousands of hours operating various types of FLIR and thermal devices as a Bradley gunner and a .50 gunner in Iraq, and in my experience the answer is pretty obvious: There will always be some contrast of temperature between an object and the background, regardless of how hard you try to mask it. The best strategy is to break up and disguise the outline of your body so your thermal signature isn't recognizable as a human silhouette.

When we were in the U.S. Cav Scouts, we were taught to never brush off dirt and debris from our gear/uniforms while out in the field, because the differences in material helped break up our thermal silhouette. Especially if it was mud. We were also taught to wash our clothes in iodized table salt, as most of the laundry soaps and fabric softeners contain optical brighteners that will light you up under NV.

@@daniel-je8xq forgive me if I sound foolish or like a complete idiot.... I am pretty knowledgeable and crafty in a few things, this however, is not one of them. I would appreciate the insight from anyone who would care to give it, but again, I am about as ignorant as day 1 on this topic so please be patient 😁.... Our local bacon factory has recently added Flock security cameras to their already vast collection of Chin@ level surveillience systems. Two months ago they also added a device that can be used remotely which is basically like an x-ray device that can be used in the field. Like it can literally see through most modern home building materials. To me that's a whole nother level of disturbing. But It got me brainstorming as to if and how it could be blocked out. I came across quite a few 5 gallons of lead paint on a job site about 6 years ago....I was told by the property owner if myself or crew wanted anything on the property to take it and trash the rest. Well I took the paint. Before anyone short circuits, I am fully aware of the dangers of lead paint as well as all the other crap we claimed to be safe building materials in the past that are now known to be rather toxic in various ways...that being said, I work in hazardous building materials mitigation. The said buckets weren't kept in the house where we were working, but in a maintenance house on the property so other than the contents of the bucket, they weren't a threat unless the seals had been broken. Although it's a pretty nasty material, if you take the proper precautions, wear the correct ppe, and let the paint cure completely, then refrain from lickin the walls or let your kid teeth on the crown molding, it's fairly benign. So my question is in theory if you stripped, painted a high grade bonding primer on, then painted the exterior of a concrete house with 8 in thick walls and layers the paint extremely thick and then when dry used an encapsulation paint followed by an epoxy exterior paint, would it be possible to block the devices view into your home? I mean on one hand, I don't have anything to hide, however on the other, I think we've let g0v get a little to comfy and nonchalant about invading our privacy. It's more the principal than anything I guess. Again if it's it sounds as dumb as the days are long, I apologize. But if you don't ask, you'll never know...

[@dc1544]

In the Army I was a 45E E5 (sergeant). That means I was a M1 tank turret mechanic. there is no way to block yourself from its thermal imaging system unless you have a underground bunker. it does 3 types of scans. density, thermal and IR. Now the smaller hand held devices can be fooled. layers of thermal blocking material with an outer layer of ir/thermal absorbing material. Special forces have said clothing. I know this because during training operations we played capture the flag with tanks, helicopters and ground troops. A special forces tried to sneak up on us and was laser tag shot. They then put on their clothes to block all. They made it past all of our troops except the M1 Thermal imaging system and we could hardly see them only their movement gave them away. So again you can fool most systems out there but movement will bust you since any object that moves will change things around it. Even masking your body shape will not work if you have experienced Gunners who know what to look for. @Charles Christianson. See you will have a unique shape and those do not move.

In my day serving in the Army infantry while being stationed at fort Hood Texas, It's kind of hard to hide from these things while you're on the move or on patrol, but when you are stationary, the best thing to do is to use a camouflage net and dig in making sure that you're using the surrounding environment to camouflage yourself with such as weeds or leaves or tree limbs. This is something that must be maintained at all times. Otherwise you will be pretty easy to see no matter what the enemy is using to search with, the more layers of camouflage you use, the better.

[@formdoggie5]

Umbrella. Glue reflective emergency blanket panels to the bottom of it. Drape conventional camo over the top of it and secure to tips of umbrella fan. Wire small, cheap, pinhole "spy camera" through the tip with viewer down to handle. From there, just stay behind the umbrella and use the camera to keep it pointed at whatever you suspect has IR capabilities. The air acts as an insulator between you and the mylar/aluminum emergency blanket, the conventional cammo over that eliminates any shine risk. If your umbrella is big enough, you can also literally utilize this system as your hidey hole tent for long duration recon (it's effectively a waterproof lean-to). Pinhole spy cameras also offer the best wide-angle non-distorted multifocal general purpose viewing, while using extremely low amounts of battery (a couple AA's will last for days). Costs less than most spend on Starbucks for the month, and you can literally fold it up and carry it collapsed on your pack, ready to deploy faster than any other option I've seen.

They also have an incredible focal field that makes them good, essentially, at any angle of viewing.

Might be an idea to make a thermo blocking umbrella. One good enough to hide under. Not only that. It might help in the rain or snow. Light weight and might be a life saver.

[@Funkteon]

Yep, that's the easiest way... I'm sharing this knowledge for the purpose of the Ukrainians trying to hide from ground and aerial thermal cameras... The cheapest and most affective way to avoid being seen by thermal imaging cameras is to acquire a large golf umbrella and cover it with a 3x3m camo net that drapes over the sides of the umbrella... When you think you're about to be spotted, you open up the umbrella and sit down underneath it so the edges of the camo netting reach the ground so you can't be seen from above or the sides. The camo netting also breaks up the smoothness of the umbrella to make it MUCH less obvious there's a non-fauna item in the thermal viewfinder... Unlike all the suggestions of thermal trapping clothing, because no part of your body is touching the umbrella canopy or camo netting, it never warms up beyond the ambient air temperature. However, it is important that you keep the folded up umbrella well away from your body during transit and do not carry it against your body or with your hands until the very last minute of deployment. Additionally, avoid moving while under the umbrella, as your feet and legs/knees/ass will have warned up the ground beneath you, and moving away from it will leave a thermal telltale sign of where you've been - once under canopy, stay PERFECTLY still... For some context on where my knowledge comes from, I worked with the UNHCR for just over a decade and now work for a civilian contractor to the Australian military.

[@JZ909]

@@Funkteon That's seems like it could work, though it may be too clunky for practical use. I would also worry about IR radiation going through the threads of the material, in the same way you can see the light from a flashlight going though the material of a shirt; I'm just not very familiar with golf umbrellas. The principle of what you're trying to do is pretty simple. You're trying to prevent IR radiation from getting to the sensor, both by blocking the IR radiation that you emit, and preventing secondary radiation from some item heated by conduction or, to a lesser extent, convection. IR reflective material (i.e. a space blanket) is excellent for blocking IR energy, and is incredibly cheap, which makes it a great layer in some system, but it's not an insulator, so without some other technique to keep it cool, it will heat up and start emitting IR energy itself.

[@Anubis78250]

Make a frame to secure the blanket/tarp as a panel and cover the outside with leaves. Really anything will work as a blind, a light frame with a handle or two and you can carry it around with you. Glass/plexy works just as well, but then you have the same reflective issues. If you know the direction of your pursuer it's easy enough with a simple panel, the real trick is something to allow 360 degree coverage while moving.

[@Funkteon]

@@JZ909 Exactly right - The method I've described prevents thermal conduction to a visible (to the thermal camera) surface... I know it works because I've literally created a couple of dozen of these setups for both myself as well as colleagues and ancillary support staff in separate conflict zones. And no, even the most technically advanced FLIR cameras cannot see IR radiation through the threads of the umbrella canopy, however, it is occasionally possible to see some IR radiation through the gaps in the camo netting from side-on, therefore, I've always made a point of telling people to crouch down and place the umbrella in front of them if they believe enemy combatants are searching from ground view... And contrary to other replies to my comment regarding the awkward/clumsy nature of carrying around a golf umbrella, I found it very easy to strap mine (with the camo netting already attached) to the side of my rucksack.

If there's enough money backing somebody that really wants to find you, there are also THz near-infrared systems similar to LIDAR that can do density mapping. Those can see through pretty much any light material, and will also make obvious any recently disturbed soil.

I was also there when he tested the first production units to see if they were up to spec. That was in a field across the street from the FBI Academy at Quantico. Here's the problem.

I have done my own test, I found that putting up a thermal backed tarp with a piece of burlap over it will stop the shine, you will also have to stand away from the tarp so you dont transfer heat to it. The more expensive thermals will be more sensitive, not sure what something from a Apache will see.

There is a huge difference between IR reflection and a thermal camera. A thermal camera do not need a light source like IR. Real thermal cameras can be bought at Amazon for above 1000$. A small experimental thermal camera can be bought at Amazon for 60$. What's required to block IR is just reflection. To make IR invisible it's just required to have a negative amplitude of the IR source. It's also possible to make an IR camera blind by just using an IR source (powerful IR light, 50$ and above at amazon) against the IR camera. Than the IR camera is just blind. That's simple.

There is no hiding from an experienced operator if you have to move and are in direct line of sight. Have tested everything you could imagine. If your stationary that is a different matter. Variables are the skill of the FLIR operator, detection range, environment conditions, type of system and terrain. What you are all not realizing is that the temperature difference not your body heat is what I will detect. All material above absolute zero have molecular movement and hence radiate thermal radiation that can be detected with FLIR. Can you beat some junk military or civilian unit? If your range is great enough absolutely. Dont confuse that with top tier units designed to detect military targets. I teach thermography to both military and law enforcement.

Second, depending on the angle of observation (i only have experience with ground units), if you dig out of line of sight you will not be observed. Understand changes in heat is what a device detects. If you use a thermally reflectant device than it will appear cold under thermal.

The keys are to limit in sight exposure, not look like a human to fool the operator, maximize detection range, and limit movement.

In addition; not trying to hate on you, but with higher quality thermals, the emergency blankets dont work for more than a few minutes, and with the systems on modern helicopters i doubt they work at all.

@@Princess_Celestia_ so you dont really, you just need to have the observer see not human shaped thermals. The whole point of thermally reflective material is to sort of mimic the heat signature of the veg around you the way surrounding yourself with mirrors in a forest would (sort of) make you look like the same colors of whats around you. Thats the basic idea, what has always been possible is simply bunding up massive amounts of insulating material (this works until the outer layer begins to warm up) however you are simply on a timer. best results i have had for extended periods of time is two layers of Mylar separated by insulating material and then that 3D shitty walmart camo netting over top which remains at the same temperature as the air and helps mitigate the issue with the cold thermals from the sky being reflected towards the observer.
