Ah well…. Give it a few more years, eh? Some enterprising soul will figure out how to create either clothing or cloaks and such, to nullify these ungodly devices… lol. Oh yea I got this one. Just like in predator. If it works for Arnold it will work for you. No, no, no, you cotton-headed, ninny-muggins… Just close your eyes. I use cheep heat packs occasionally to sight in my XP50 thermal. Stands out like dogs balls. Cheerio from Australia. A decoy is always a great tactical asset.
It will alert them that someone is in the area which may intensify the search in that area. Situations vary, and I can see a few times where this may well work in your favor, but not the majority. Just crawl underneath a car or a truck close to the transmission or engine the heat from the car will hide your heat print. Some may find the information useful. Had the umbrella thought after thinking would it work to set a space blanket as an over head tarp, but wanted to move around.
Any chance of moving the notify to follow up comment button a little further from the post button? If you know exactly where you would be viewed from, this might work.
However, the umbrella is quite portable unlike some other possibilities. I had this idea, but with another layer of dark material on the bottom so you could use the umbrella without giving away the reflective layer. This is something you would use in combination with tree cover, other heat sources, additional improvised barriers and the like. Would that be effective at hiding the bug out house perhaps? Line the exterior and add environmental camouflage to the top of it..
Unless you are in some sort of complete cover like a cave, bunker, or well designed spider hole, it will be very hard for the average person to counter thermal imaging, especially if moving. If anyone ever creates some sort of clothing that will counter thermal imaging, then that may help, but otherwise I really have no idea how to counter thermal imaging if you are in any way exposed to being viewed from any angle.
I wonder how effective cold water or dirt piled on corrugated steel would be in deflecting aerial surveillance. Thanks FL Flatlander. I thought I would get some more serious answers here on this web page..
Looks like most of the respondents are juvenile libtards. Dirt would definitely help. To work well, you need a good layer a few inches thick, so you need decent support for your corrugated steel. Better yet would be to have live foliage over your dirt, since the dirt itself will appear differently than foliage and a base geometrical shape will scream man-made and draw attention even to the visible eye.
While the article is more specific to IR, you need to be hidden from IR, low-light and visible capabilities. I believe the umbrella with space blanket material would probably be the most practical and effective solution. You just open the umbrella towards the thermal imager, but you have to know where the thermal detector is located. For example we know from what direction, usually the sky, the rain is coming from, right?
The umbrella idea sounds as if it would work… anyone with one of the thermal gadgets to test ideas with? The need to keep your stuff light is very important. What if you sandwiched it in the middle of a quilt?
There are already companies selling them and giving the instructions away for free to anyone who wants to build one. I have two thermals and neither can detect anything. You can search on youtube to see the videos. Defeating Drones. I got my radiant barrier from a online company that sold it by the yard. Is this a correct assumption?
Nice job stealing content from Tin Hat Ranch! What a tool! Just stop. A review of the material followed by a link would have been acceptable to all parties. But this is not. This article makes it sound hopeless and thus pointless. The original article does not. Anyone seen the Cat s60 phone? I would sure like to see a review from a preppers perspective. It might be handy to use the technology too. And to learn the limitations.
Just fart continuously and any heat seeking rounds will be confused by the hot gas and veer off and miss you. I once worked with these devices as well as other detection and assessment equipment. Now, understanding that it was 20 years ago, this may not apply to the therma imaging devices currently available but the easist way I found to spoof them was with a stand-off shield made of corrigated cardboard. It would be nice to hear from people who actually have a thermal imager and hear what they have to say about their experimenting on this topic.
I do like the umbrella idea but…. Twenty-five minutes later the gunny stood up fifty yards away from the demo group. He had used a ghillie suit over an umbrella and just inched up on them.
They were busy chatting, depending on the thermal imager to detect him and not watching in front of them. They would have been DRT. A shelter drapped over an uneven leanto. Made by sandwiching a wool blanket, Mylar blanket, then layers of branches. If your ground is the same temp as surrounding ground, you have a winner. My neighbour has three thermal imaging cameras focused into two windows into my house.
Will the heat lamp facing each one confuse what is seen when I move about? I have designed a system for this type of warfare. I wish I could share with yawl, but then it could be looked into and possibly a counter system designed to defeat my system. It is however a two way system. It detects and hides. Just walk on all four to make it look like you are an animal. What about tin foil if you cover yourself with it? You see Satan, AKA my wife, has no heart.
Her chest registers black with thermal imaging. The rest of her shows up as shades of gray and no, not fifty shades of gray. This has been tested and proven. Thank you for this article, Ferguson.
It is an excellent introduction. The Mylar can go over it. Small holes will leave small bits of light that will blend into the background and allow body heat to disperse. And it can be stored with the bug-out bag. Thanks for the comment. They make umbrellas for photography with the mylar already built in on the underside. You might want to look into that before you go building one. Just thinking out loud here, but what if you made a ghille-like suit out of layered strips of camouflage cloth sewn to strips of mylar as backing?
My thoughts exactly. I was actually on Google NSA search engine try to see if anyone has done this…. Recently some Texas students proved to DHS that with a couple hundred dollars in parts they took control of a predator drone while in flight…someting to look into learning maybe?
Oh and it was proven the same with planes. As has been mentioned it should be covered with fabric, clay, paint, grease, to name a few. If you do not have space blankets on hand, round up as many Chip Etc… bags as you can and wrap yourself under your outer wear.
Adjust for climate differencial, given the heat retention factor. Small ones for socks and hand covers. Though your signature from small regions such as hands, feet, face, will register from a distance as nocturnal species about in the night. Then there is the bug out via boat issue. Engine heat is your enemy. Same type of system over your outboard to get out of your preexisting FEMA camp.
Islands, across rivers, lakes, et al. Keep it quite. Though the Ocean is a big region, and with its usual swell, the up and down will also aid in camouflage…. The car windshield visors with mylar covering and a foam insulation in side may work. There are civilian versions of IR detecting dvices that are able to detect temperatur differences of less than 0.
There are also systems with software that detect movement. Such cameras are used to detect gas leaks for excample. There is one thing that make deetction difficult and this is distance. Because IR lenses are super expensive and because of the huge diffraction of long wavelength simple physics IR imaging systems have far less resolution that optical imaging devices like your ordinary digital camera.
So I doubt that a drone flying really high! Why not use highly reflective paint on a double pane window glass that blends in with the surroundings. The paint will have an emissivity that is higher than the glass thus giving you a variable IR signature yet will not allow the persons body heat to be seen through to the collector. If all someone is looking for is a camoflaged hidey-hole, this would work great. If one is looking for mobility, why not a ghillie suit of reflective mylar with a plexiglass face-shield such as those used in arc-flash protective equipment?
You would have to keep cool packs handy. I have actually been designing a temperature controlled suit to wear that effectively blocks Thermal Imaging and Infra Red detectors as well as any visual observation system cameras. It involves an thermally insulated suit and a build in liquid cooling system to keep body temperatures at an ideal temperature via a controller regardless of what the outside temperature is at.
The best part is that it is also very water resistant. Lemon Pledge is what I was taught with but there could be one better suited for this project. I would think you could do that with all of your clothes right and shoes or boots also correct and then something to cover your face and head? Design a temperature-controllable suit for the entire body and make it adjust the temperature of the suit to match the ground temperature, thus effectively camouflaging the wearer.
Small temperature probes on the bottoms of boots would detect the ground temperature. This is entirely possible, but only with a significant amount of time and money. With liquid nitrogen for example. Just a little. It would turn into a gas which will go through a hose cooling the body. Would that work? Btw…you were talking about scopes,right? LN2 is not too good an idea. It cannot be stored for very long since it will evaporate all the time.
Trying to pressurize it to stop the evaporation will result in an explosion! I might add that being odorless, colorless and tasteless, it can be VERY dangerous since you can be asphyxiated and not even be aware of the danger!
It is being considered as a humane way to execute people since breathing it makes you pass out and die before you are even aware of the danger. The Army guys had trouble seeing through the acetate covers of billboards when in Iraq. Glass and acetate may have the same properties but im no expert.
Ive coated an existing umbrella with acetate. Consider as well a water bottle to mist the umbrella to keep it cool for extended periods if necessary. Sew strips of cloth or rope on the umbrella allows one to weave branches and brush in. Palm leaves stay very cool. Another idea is to warp your heat signature.
Complete coverage may not be necessary but enough to not look human. Soil maintains about a 54 degree temp.
Burial or partial burial may help or even a soil roof like the old dugout cabins. Unfortunately you cant avoid detection if you are in the open , heat builds up behind blankets etc ,the best plan is to dig in but even then you can be blown out of the ground! Best way is to hide amongst government officials!
If you happen to be military in nature, or have served, the book is a must read. Much of our military indoctrination is contrary to Survival. Think about that for a moment. The best way to avoid IR detection is to cover yourself in pig shit and roll around in the mud making grunting noises. What about interspersing mylar strips into the burlap strips of a ghillie suit? Seems like the coarse burlap would help disapate escaping heat and break up the visual outline while the mylar strips would help break up the heat signature outline.
Since they are strips rather than a solid sheet, the heat retention would be minimal. As more and more people realize the great potential of this imaging technology, thermal cameras are being used today in many applications and many different ways. In many countries worldwide, thermal cameras play pivotal roles in a wide range of government, commercial, and industrial activities. So in the future we can expect there will be measures to control the misuses.
I found this batting years ago, it is meant to line oven mits. But I purchased 4 yards of it and inserted it into a duster including the hood. That was the point, built it after watching a history ch episode on the evolution of night vision.
Midwave um is a mix and will see a space blanket in the woods…while SWIR. Your best bet is more of a combination of things. Overall a great starting article, but before you take this tidbit of info and run you should research more how infrared works. Source from working in the infrared optics field. There is no one wavelength or one way. They all have balances tho. LWIR is great for seeing detail in large temperature swings is people next to a forest fire but the resolution of the microbolometer that is most often used is poor.
You can tell if people are next to the fire, but you are never going to tell who it is. MWIR is much better at detail because of the shorter wavelength also research nyquist frequency but is easily blinded with something hot ie a flare next to your face makes it very hard to see features. SWIR is great at seeing through moderate fog and smoke, but starts to get blinded by smoke that is lit up since SWIR is almost all reflected light.. Camouflage is all about who is looking for you.
We wear orange into the woods so other hunters can see us, but deer only see gray. A good guille suit apologize if poorly spelled with native vegetation will break up your outline a lot.
Bit off topic, but was wondering if there is any substance, may be an inch big in size which could emit heat higher than body temperature. The reason I am asking is, I am using PIR sensor to detect the motion, but I what if I want to detect the motion of the one particular person, I though of having that heat emitter hooked on that user and then detect that person instantly as the heat temperature will be higher. I have a problem with my home security camera. Is there any type of filter I can use that will allow my camera to work?
You might consider moving the camera to the edge of your property and aim it back towards your place or add a camera to the system in this position because it will stop that blocking nonsense, give you access to car tags and still allow you to see what your wanting. I know how to stop them from getting heat signatures from me.
Either a large baseball bat used on their equipment or a few well placed bullets into that same equipment. I just loved that video on the news about 6 months ago where the guy did some skeet shooting with his shotgun on that drone hovering by his house!! Trust me, they are the least of your worries. Thermal and IR Infrared , incidentally, are not the same thing.
These include all M1and M60 series tanks, M2 and M3 Bradleys, Dragon missiles and even individual sniper weapons such as the Mseries rifles. During the Persian Gulf War, Battle of 73 Easting, at least one T was destroyed due purely to its exhaust being visible from where it was hidden behind a berm.
The tank was hidden behind a bulldozed berm, and according to tank doctrine for defense, it would watch for American tanks, pull up to clear the berm, and shoot at them. The driver would throw the tank in reverse as soon as the cannon went off, and duck back behind the berm. I like this post. Have been wondering how to accomplish hiding our body heat. There is some very informative ideas and information. For many of us though the simpler the better.
So I appreciate the help with that. If the soaking of cotton material works, that application would be helpful in many situations and convenient to achieve. I really enjoy it when we add our knowledge and ideas in the comments. As far as avoiding Infrared detection, there are allot of factors to take into consideration when determining what method s to use to conceal your IR signature….
Keep in mind, not all IR is thermal based. Night Vision also utilizes part of the IR spectrum to enhance images by combining it with the part of the spectrum we can see, but it does not include the thermal information. Thermal detection produces a different set of information based on temperature differences. Even if you could completely conceal yourself from thermal imaging detection, you may still be plainly visible to simple night vision.
Some of the ideas offered will be more effective for a stationary position such as a guard post, entrance to your BOL, etc. These will trap heat and thus, you will start getting hot rather quickly. They only provide a brief concealment. Is it a human with an IR scope? You may or may not detect a human being using an IR scope. Thus, you may not know where that person is, from what direction they are looking, how far away they are, etc.
In fact, you may never know they were there in the first place. A civilian drone with a FLIR camera? Civilian drones have limited range and flight time. They tend to be pretty noisy and are more easily detected.
Military drones are going to be undetectable to most people. They can fly high enough to conceal their sound. They can stay aloft for 24 hrs on a single tank of fuel.
They have multiple cameras that can be used in concert to detect you. These include regular cameras, IR cameras, and cameras that can see through air obstructions such as smoke and clouds. They can also carry ordinance to use on targets. A helicopter? Helicopters are loud, and thus will likely be used more in a pursuit scenario where the presence of a target is known, rather than in a general surveillance mode. Rain, wind, and other environmental factors can work for or against you. For the purposes of thermal imaging, you want to be at or very close to the temperature of your surroundings… that is hard to do.
Trying to contain our heat signature will not work for long as Ken pointed out because we will either overheat, or the body heat we are producing will start to seep out at the edges, or both. There are some neat ideas out there. Try doing an image search on terms such as hiding from thermal detection, mylar blanket thermal camera, etc. You will see success and failure. An idea I have been considering for a while is two lightweight but large wool blankets with a sheet of mylar sandwiched between them.
It would be portable, effective for longer than simply a mylar sheet or a wool blanket alone, and would serve another purpose as it would also help keep us warmer in colder weather. I look forward to seeing more comments. Make your wife wear a hoop skirt lined with mylar, in the style of the fashion of the Civil War…and hide under it…as she walks about with a mylar parasol. If you are being targeted by a non-governmental adversary that has such equipment, it would be survivable.
What will stop a bullet will also block the imaging. Since the time this article was first posted it has been a popular hit on search engines. I decided to update it somewhat and re-post it today, years later for further comment. I am just not worth the effort. If I am the last holdout for whatever, the country is really screwed. Hell, I only have rolls of TP. NRP Ran out of room. Adapt and …. I did use the hand-held bidet to stretch my TP, but like any mechanical device, it crapped out after three years.
I think now, I will just leave IR thermal imaging signatures all over the woods — that will confuse the feds. The original article suggested a Ghillie suit could help. So how about a Ghillie suit fashioned from strips of reflectix? It is not a practical solution, though, due to the obvious impracticality of carrying around a pane of glass, or constructing your walls and ceiling out of glass. The foil will block the IR heat signature behind it. A problem, though, is that whatever it is that you are attempting to conceal, its heat will either build up inside to an unbearable degree or it will escape somewhere, which will then be visible to IR imagers.
Concealment, for the most part, will be temporary without elaborate mechanisms to disperse the heat signature. For a quick temporary method of IR concealment, throw a blanket over yourself. A thick woolen blanket will help defeat thermal imaging.
This is only temporary concealment as the heat builds beneath the blanket, but it may work long enough to conceal during a quick TI scan or Drone flyover. Other methods of partially hiding from IR is to conceal by blending in with other warm objects like stones or thick walls that may still be holding the heat from the day. The vents in buildings may be out-flowing warm air — a source of heat that can help obscure your own thermal outline. You get the idea. Wherever there is existing natural or man-made heat, you can blend in with that to help conceal your presence to an IR or thermal imager.
Another strategy is to wear an insulated jacket, insulated pants, and a hat. Again, the heat will build and escape through the neck openings and face. You could cover your face with cool mud, which will work temporarily. This type of netting will help somewhat, but the holes throughout the webbing of the net will reveal some of the thermal IR heat.
Netting will help to disperse the heat that may be underneath it as the airflow will be broken up somewhat by the webbing and will hide or smear hot spots better than having no cover at all. The heat signature will not be as intense, but spread out more.
An example may be to cover a vehicle that has been running with netting, or to wear a Ghillie suit. Trees overhead will help break up the infrared signature, especially under a heavy canopy of leaves. A moving heat signature at night is quicker to identify than a stationary one up to a point. Avoid open spaces and skylines by day or night, and keep in mind that thermal imaging does not perform well in falling rain. Surely this is better than otherwise, but keep in mind that the objective is to blend in with the thermal clutter of the surroundings.
The problem with most IR cloaking methods, whether IR clothing or netting designed to block IR, is that it will also block the background IR creating a black hole of varying degrees. Ideally you would want something that cloaks or blends your IR signature such that the background scatter at your location is what the observer sees.
We are entering the age of the Drones, and there are all sorts of levels of detection capabilities, but to avoid being detected, starting with the basics of ordinary IR heat signature, is at least a start. For more information about thermal imaging, read this article. I was wondering if there was a way to test what they call a H.
