How to defeat infrared night vision and Thermal Imaging

Night Vision

The surveillance technologies enabling image capture in little to no lighting are intensified , infrared (IR) and thermal

imagery. Let’s take a closer look.

Intensified Amplifies Existing Light



Technology advances in the past 20 years have resulted in great improvements to the performance of how well intensified

CCDs pick up images in low light.

The first area of lo!light systems open for discussion is knon as the intensified charge!coupled device (I""#).

This method of night vision amplifies the e$isting light. It focuses the e$isting light on the photocathode of an

intensifier. The light causes electrons to be released. These electrons are then accelerated by a high voltage (about%&,''' times) the accelerated electrons are focused onto a phosphorous screen. The energy of the electrons makes

the screen glo, hich in turn is received by a ""# sensor producing a video image.

Technology advances during the past ' years have resulted in great improvements to the performance of intensified

devices. Their ability to identify people and ob*ects at very lo light is its ma*or advantage. I""#s also offer high

resolution or detailed images in e$treme lighting environments. +oever, I""#s do reuire some e$isting light in

order to function. Intensified ""# cameras also produce a poor daytime image hen compared to day!only cameras.

-o hat do e do if there is no e$isting light available IR lighting is one possible solution.

IR Works With No Visible Light

IR lighting is a light source designed for black!and!hite cameras or the ne day/night sitchover surveillance

cameras. It is incorporated for e$tremely lo! or no!light applications. This light source has little or no effect on the

spectrum of light that the human eye uses to produce an image. Therefore, applications here video is reuired but

the use of visible light is prohibited are cases in hich IR light is e$tremely helpful.

IIR light can be split into three categories0

1ear!infrared (near!IR) 2 "losest to visible light, near!IR has avelengths that range from '.3 to %.4 microns, or 3''

billionths to %,4'' billionths of a meter.

Light Spectrum Chart: ! light has little or no effect on the spectrum of light the human eye uses to produce an image. t"s

well suited for applications where video is re#uired $ut the use of visi$le light is prohi$ited.

5id!infrared (mid!IR) 2 5id!IR has avelengths ranging from %.4 to 4 microns. 6oth near!IR and mid!IR are used

by a variety of electronic devices, including remote controls.

Thermal!infrared (thermal!IR)2 7ccupying the largest part of the infrared spectrum, thermal!IR has avelengths

ranging from 4 microns to in e$cess of 4' microns.



The key difference beteen thermal!IR and the other to is that thermal!IR is emitted by an ob*ect instead of

reflected off it. The near!IR range is by far the most popular. The main reason is the cost of the euipment. 8nlike

intensified and thermal cameras, near!IR emits a light source in order to illuminate an area.

The other methods rely on e$isting light or energy to produce an image. Therefore, many more factors must be taken

into account hen selecting near!IR euipment. They include the avelength of the emitted light, and poer and

degree of coverage.

Wavelengths !ower and "overage

1ear!IR can have an 9&' nanometer (nm), 99'nm or :;'nm avelength light source. The selection is based on

distance and the covertness of the application. < camera incorporating an 9&'nm light source can be detected by the

human eye. Thus the covertness of the unit is very lo hoever, the operating distance can be more than ='' feet.

<s the light source increases in nanometers, the ability to vie the source becomes less. <t :;'nm, the source can

only be vieed by another IR!sensitive device and not by the human eye. The draback is that the overall operating

distance has also been reduced.

>hen you need to see in the dark, you get a flashlight ... ell, IR operates as a flashlight to IR!sensitive cameras(black/hite or true day/night cameras). The greater the distance reuirements, the greater the poer (attage)

reuirements ill be.

<dditionally, the angle of coverage must also be factored hen planning for distance reuirements. In most cases, to

achieve e$treme distances the angle of illumination is reduced. The angle of the lens on the cameras should closely

match the angle of the IR unit. < mismatch may produce images that are unacceptable for video surveillance.

IR #afet$ "onsiderations

<ny research done on IR illuminators ill alays being the topic of eye safety. -ince the IR spectrum of light is

invisible to the human eye, the iris ill not react. This may cause some damage to the eye. #epending on the light

source the safety reuirements ill vary.

The older style of illuminators incorporated large lamps that could reach distances of %,''' feet or greater. +oever,

they could cause eye damage if vieed from a distance of = feet or less. 1eer, safer versions of IR illuminators use

L?# (light emitting diode) arrays and are governed by Laser ?ye -afety ?1='9&!% or ?1='9&!%5.

In ''%, the standard governing the safety of laser products in ?urope (?1) and Internationally (I?") as

substantially revised and the classification system as overhauled This resulted in the introduction of three ne laser

classes (%, %5, 5 and 4R) and the abolition of "lass 4<. The ='9&!% standards apply eually to lasers and L?#s.

The ord @laserA here is interchangeable ith @L?#.A Benerally speaking, L?#s ould be in the loer classes (%, %5,

, 5, 4R), but very e$ceptionally may be "lass 46.

The phrase @eye!safeA is used in the classifications that ill follo. Clease note this term is applicable to the hole

optical spectrum from %9'nm to %mm (millimeter) avelength, not *ust in the retinal haDard range of ;''nm to%,;''nm. 7utside the retinal haDard range there is potentially a haDard to the cornea. < avelength outside the retinal

haDard range is therefore not automatically eye!safeE

+ere is a brief description of each of the current laser classes that are most relevant to our surveillance discussion0

"lass %

This class is eye!safe under all operating conditions.

"lass %5



This class is safe for vieing directly ith the naked eye, but may be haDardous to vie ith the aid of optical

instruments. In general, the use of magnifying glasses increases the haDard from a idely diverging beam (e.g. L?#s

and bare laser diodes), and binoculars or telescopes increase the haDard from a ide, collimated beam (such as those

used in open!beam telecommunications systems).

Radiation in classes % and %5 can be visible, invisible or both.

#ele%ting &ear for IR Appli%ations

<s mentioned, IR illumination is only available hen incorporating black!and!hite or true day/night cameras.

@TrueA has been added to the day/night selection because some of the cameras carrying that designation on today’s

market do not remove their IR!cut filter, hich can affect IR functionality.

The IR!cut filter is a mechanical device located in front of the image sensor. #uring daytime hours the filter is set in

front of the sensor in order to produce proper color images. In lo!light or night applications the filter is usually

removed from the front of the sensor in order to add IR functionality. >ithout the removal of this filter IR

applications are very limited.

<nother area to consider is proper lens selection. >e talked about ho the angle of the lens should also match the

display angle of the illuminator. 6ut that is not the only reuirement. The selected lens should also be IR corrected.

This correction ithin the lens allos the visible light range and the IR light angle to focus on the same vertical/focal

plane. < non!IR corrected lens ill produce a ell!focused image until IR illumination is supplied.

The use of IR lighting has been around for many years. 1e techniues including advancement in L?# arrays and the

integration of illuminators ith camera systems, especially hen using pan/tilt/Doom (p/t/D) euipment, have

launched many ne applications.

The main disadvantage is, depending on the scene content and lens angle, positive identification of ob*ects may be

impossible. -ince IR is a light!generating source, long!distance surveillance can also be limited. 7verall though, anaverage surveillance system can definitely be enhanced using IR for lo light applications.

Thermal Works in Total 'arkness

The last area for seeing in the dark is thermal imaging. Thermal imagers are forard!looking IR (FLIR) devices. That

acronym as generated by the 8.-. military here the technology as first utiliDed. -ome of the first thermal imagers

ere mounted on the front of reconnaissance aircraft.



Thermal imaging allos people to see in complete darkness. 6oth intensified cameras and IR illumination reuire

some lighting in order to be effective. 6y contrast, thermal cameras detect the smallest changes in temperature

beteen ob*ects and turn it into a video image.

<ll ob*ects emit a certain amount of black!body radiation (defined as an ob*ect that absorbs all electromagnet

radiation that falls onto it no radiation passes through it and none is reflected) as a function of their temperatures.

Benerally speaking, the higher an ob*ect’s temperature, the more black!body radiation it emits.

< thermal camera can detect this radiation in a ay similar to ho an ordinary camera does visible light. It orks

even in total darkness because the ambient light level does not matter. In addition, thermal cameras can penetrate

outdoor elements such as smoke, fog and haDe.

"ooled and (n%ooled 'ete%tion

"hoosing a thermal camera may seem like a difficult task. 5any people are reluctant to make any selection on their

on due to the lack of information and the high cost of the devices. Let’s start ith the basics and see if e can’t make

it a little less intimidating.

Thermal cameras can be cooled or uncooled. This indicates the type of detector the camera has incorporated.

"ooled camera detectors 2 This type of thermal cameras have an imaging sensor that is cryogenically cooled.

"ryocoolers are devices used to reach cryogenic temperatures belo !%&'G ", !49G F or %4G H by cycling certain

gases. "ryocoolers have moving parts engineered to specific mechanical tolerances that ear out over time. These

devices loer the sensor temperature and reduce thermally!induced noise to a level belo that of the signal from the

scene being vieed.

This type of camera is the most sensitive to small differences in scene temperature, called thermal contrast. Thermal

contrast is the change in signal for a change in target temperature. The higher the thermal contrast, the easier it is to

detect targets against a background that may not be much colder or hotter than the target. "ooled cameras are very

costly and reuire yearly maintenance for re!calibration. They also have a 5T6F (mean time beteen failures) of

,&''!9,''' hours.

8ncooled camera detectors 2 8ncooled cameras are generally less e$pensive than their cooled counterparts. <s they

have feer earing parts uncooled cameras also have longer service lives. 8ncooled detectors operate at or near room

temperature rather than being cooled to e$tremely lo temperatures.



>hen IR radiation from lo!light scenes is focused onto uncooled detectors, the heat absorbed causes changes to the

electrical characteristics of that detector. These changes are then compared to baseline and a thermal image is

created. 8ncooled detectors offer loer image uality than cooled units hoever, this technology makes thermal

cameras much smaller and less costly. This opens up many ne avenues in the security marketplace.

The last area one may find on the specifications for a thermal camera is the array configuration of the uncooled

detector. 8ncooled thermal imagers are available in to different configurations0 micro$olometers and ferroelectric

arrays.

< microbolometer is a specific type of resistor used as a detector in a thermal camera. It is a tiny vanadium o$ide

(7$) or amorphous silicon (a!-i) resistor ith a large temperature coefficient on a silicon element. 7$ thin film is

the most idely knon and used material for uncooled microbolometers due to its high temperature coefficient of

resistance (T"R) at room temperature. Infrared radiation from a specific range of avelengths strikes the 7$ or a!-i

and changes its electrical resistance. "hanges in scene temperature cause changes in the bolometer temperature,

hich are converted to electrical signals and processed into an image.

5icrobolometers have a very distinct image ith crisp edges on the ob*ects in the scene. +oever, the dynamic range

of temperature for a microbolometer is somehat limited hen compared to ferroelectric arrays. This fact becomes

very evident hen looking at a scene here a fair percentage of the vieing area is deep space, such as a desert or

large body of ater.

Ferroelectric detector technology takes advantage of a ferroelectric phase transition in certain dielectric materials. <t

and near this phase transition, the electric polariDation of the dielectric is a strong function of temperature. -mall

fluctuations of temperature in the material cause large changes in electrical polariDation. If the sensor is kept at a

temperature near the ferroelectric phase transition and the optical signal is modulated, an IR image can be obtained.

This techniue allos ferroelectric arrays to encompass a large dynamic temperature range, and even look directly at

the sun ithout incurring any damage to the detector. The image uality is not as sharp as a microbolometer but mostusers find it difficult to distinguish beteen the to. Ferroelectric arrays are slightly less e$pensive and can

outperform microbolometers in desert or large body of ater scenes here deep space is a factor.

Thermal Re)*ires #pe%ial Lenses

Lenses of thermal imaging cameras are different from those of normal



Thermal cameras detect the smallest changes in temperature $etween o$%ects and turn it into a video image. Courtesy &L! Systems

Blass does not transmit IR radiation ell and so the lenses for thermal cameras are made of germanium. This

material is a good transmitter of IR radiation. +oever, it is very e$pensive.Long focal length is another factor that can add to the cost of uncooled thermal cameras. This relates to another

crucial lens parameter 2 the f!number. This factor is not only important for thermal it also is a ma*or factor for any

lo!light surveillance system. The f!number determines the light!gathering poer of the lens and, therefore, affects

the overall sensitivity of the camera system.

Thermal cameras can see great distances, but accomplishing this means the focal length of the lenses must increase.

<s the focal length is increased the diameter of the lens aperture must also increase to keep the system f!number

constant.

<n uncooled camera has to be operated at a lo f!number (typically %.; J f!stops) to achieve the sensitivity

comparable ith that of a cooled camera. +igher f!numbers reduce uncooled camera sensitivity and there is no

ad*ustment to compensate for the reduction in the light signal transmitted through the lens.

<ll this means that long!range thermal surveillance applications reuire long focal length lenses. The cost of lenses

rises rapidly ith focal length for uncooled camera systems and rather sloly for cooled systems. <s a result, even

though the cost of a cooled camera is much higher than an uncooled camera, the overall system cost for uncooled

could surpass the cost of a cooled thermal camera system.

8sing the same technology as airborne la enforcement units, +!-eries gives officers the information they need to

make uick decisions, enhancing mission effectiveness, ma$imiDing operational capabilities, and improving officer

safety.

Ceople can’t hide their heat, so +!-eries lets officers0

-ee suspects in total darkness

-ee through smoke, dust, and light fog

-ee through camouflage and foliage in any lighting conditions

-ee more K and see farther K than ith other lo!light night vision goggles and cameras.



8sing a 4' ;' thermal imaging core, +!-eries provides four times the image clarity and detail of earlier systems,

alloing officers to see more of their surroundings than any other night vision technology in the orld. FLIR’s

advanced image!processing algorithms produce, crisp, clear thermal video day and night, in good eather and bad.

6est of all, +!-eries is the first personal thermal imaging camera affordable enough to give every officer on the *ob the

unsurpassed tactical advantages of full!resolution thermal imaging night vision.

Flashlights only illuminate a small area, plus they give aay your position. +!-eries let you see clearly in total

darkness hile staying covert.

Image intensified night vision scopes can’t help you see things that are camouflaged or that have lo visible contrast.

+!-eries cameras don’t saddle you ith any of these limitations.

0ETH.'# .+ 'EALIN& WITH IN+RARE' AN' THER0AL I0A&IN& 'EVI"E#

<ll it takes to defeat infrared night vision, and I mean the B77# -T8FF, is a single sheet of %

mil polyethelene plastic.

I tested only the thin film polyethelene that >al 5art sells as a painting drop cloth for :: cents.

It orks folks, and I ill tell you ho I kno.

It is completely effective against government issued infrared night vision, both the hand held

and helicopter mounted units.



This is hat you need to accomplish for it to be effective K

1ever have it rapped tight on your body or your body ill arm it up, and then the plastic

itself ill radiate infrared.

Mou have to have it e$tremely loose on you so that it stays cold. 1o here on you should it be

close enough to you to be armed by your body heat. < couple inches ill do, it *ust cannot be indirect contact ith you.

< loosely draped arrangement, and hen you lay don, put it over you like a blanket.

7bviously if night vision is in your area you donNt ant to be out alking around, one snag on a

tree branch and you could easily be finished. -o movement ill be slo.

This as tested on the 8.-. border patrol, against numerous helicopters, surveillance drones,

and -8Ns. I as in the back country for three days on my first border bust attempt, and evaded

them entirely hile they ere everyhere. <nd finally I got tired of the plastic, convinced myselfit did not ork anyay, and stood up 71"? ith it off and got bagged immediately.

Bet the #eLorme topo map of your state that they sell at truck stops. ItNs the one that is a full

siDe book. #onNt get the national one, get the one for your state. In it ill be the full

topographical information for the state, hich is great for back country navigation because these

maps include all the ; heel trails, possible obstacles, lakes, rivers, and most importantly, the

TI#<L -CRI1B-.

INd bet you never heard of a tidal spring before, but knoing hat one is can save your life.

#onNt even think about lighting a fire ithout e$treme caution, satellites are atchingE

The Fed thought of this years ago. 8nder the disguise of catching forest fires early on before they

got out of control, the Fed launched satellites to look at the back country and detect hen a fire

starts. This as stated as having been done to give a first arning of a fire that needs attention.

6ut since forest fires get out of control all the time, itNs obvious the satellites are there for other

reasons. <nd I can guess hat reasons.



Interesting. Mes that ould ork. To a point. Mou do have to move eventually. <nd it depends on

other factors such as ambient back ground temperature, camera settings, softare, etc.

If you are discussing Thermography, that is a little tougher to hide from. Mour body heat rises

and can get around a piece of plastic. 8nless you seal yourself in, in hich case you might die of

suffocation before they can find you. <nything that prevents your Oheat signatureO from being

visible is useful. +iding behind a tree is enough if you kno here the surveillance is coming

from. < chopper over head may be running ithout lights or far enough aay that you donNt

hear it. Ceople ith scopes or thermal imaging euipment see different things, depending again

upon the settings, softare, background temperature, etc.

Mou could dive into a body of ater, you could ear a et suit (or dry suit). Mou could hide in a

culvert, or blend in ith a Ohot spotO like an air conditioner or car that has recently been driven.

Mour heat signature ould OmergeO ith the other thermally OhotO item and make you harder to

pick out of the background clutter.

<s long as you donNt peek out or stand up suddenly. 5any layers of clothing tend to trap heat as

ell but ould be useless if you didnNt ear gloves and cover your face. Look at this image0

The officers are guarding a 1uclear >aste train. Their Omid sectionsO are opaue to the imager

because they are earing bullet proof vests. +ers another taken ith different temperature

setting on the camera0



1otice the difference beteen the to. 6efore you begin filming a camera has to be programmed

for background and OthresholdO temperatures. -etting a hi lo range for the display to represent

the colors for differing temperatures( if in color mode). -o, belo a certain temp, the back

ground can appear black or be assigned a color. Its kind of like a gain control or ObrightnessOsetting. Thermal imagers see O+eatO not visible light. They operate in the Infrared spectrum.

+eat behaves like light. Thats hy you feel the heat from a fire on your skin. The radiant heat

energy travels through the atmosphere *ust like light photons. <t the same speed as light.

The camera sees and displays the difference in temperatures in its field of vie. -o the face of a

person is hotter or higher on the color scale than the persons clothing and higher than the

ground or buildings. If a roof is hotter than a all for instance then that is displayed in the ne$t

color on the graph.

Thats ho you can see the train has moved recently, the colors of the brakes being applied are

OhotterO than the cars themselves. The heat from the nuclear aste is arming the containersand the train car alls because it is heating it up from the inside. Like a arm coffee mug. Mou

are not seeing the Radioactive aste inside its container, you are seeing the arm skin of the

outside of the rail car. That tells you something inside there is arm.

Like these to pics0

The top one is of a half full ater tank in visible spectrum and the bottom thermal image shos

you the ater line. Mou arenNt seeing the ater in the tank, *ust the difference in temperature of

the outside of the tank at the ater line.

This guy is either a liar, and idiot, or both. INm picking option 4. +aving said that, if someone

here on <T- can test his claim about this defeating 1ight ision INd like to hear about it.

>ouldnNt a couple of boating flares Peither the sticks or those fired into the airQ overload the

nightvison rendering it useless



Cersonal #isclosure0 Flares also may be useful screening against thermo vision or heat seeking

pro*ectiles although I am uite unsure about the former compared ith the latter.

I used to on a ',''' thermal camera and you can hide from it behind a glass, it cant see

thru glass.

>o, I canNt handle the level of complete 6- INm seeing in almost every sentence in this threadso far. If you donNt kno hat youNre talking about then donNt post it as fact. I on a thermal

imager and I ill happily go about making you look like a fool *ust to teach you not to post crap.

Ceople on <T- are here to deny ignorance not gain it.

First, the uoted information in the 7C is a complete lie, probably by somebody ho ants you

to think youNre sneaking through security unseen. < thermal imager cannot see through very

many things at all but the 71? thing it can see through is thin plastic sheeting. This means poly

tarps, vapor barrier, garbage bags, cling rap and practically anything similar. In fact I use cling

rap to protect the lens of my thermal imager in dusty environments or bad eather. I put it

right over the lens and the imager sees through it almost like itNs not there.

-econd, you do not need to seal yourself into something to the point of suffocation in order to

hide from thermal imaging. This is because the atmosphere is transparent to most thermal

imaging technologies so your arm breath cannot be detected. The fart videos on MouTube are

faked ith aerosol cans. That is hy the fart is registering as a colder temperature rather than armer. It is the depressuriDed, thus colder aerosol particles that are being imaged, not the air.

Thermal imagers cannot see through foliage, blankets, tent nylon, or anything solid. They can

see any heat on these materials that has conducted into them from behind via direct contact.

This is hy a sleeping bag hich has insulation providing a no contact Done beteen you and the

outer layer orks so ell. 5ake sure you store the sleeping bag aay from your body before use

so it isnNt heated up. Rebels in <fghanistan, and Ira have been avoiding detection from 8-



military grade thermal imagers for decades simply by ducking under thick, ragged cut blankets.

#ense spruce trees are an e$tremely effective cover from thermal imagers. Thermal imagers are

practically useless in urban environments during or after a sunny day and their effectiveness is

significantly reduced in rural environments after a hot day, particularly in the earlier evening

hours.

That is the time for mobiliDation. If itNs been an overcast day then thermal imaging effectiveness

that night is at itNs peak. 5ice, sleeping birds and even ant hills ill stand out like ild fire.

Third, ho the heck aves flares around to avoid detection I canNt even e$plain hy someone

ould suggest this. It onNt foil a thermal imager. The operator ill see some hot body aving

even hotter items around.



INve heard people suggest lighting a bunch of fires to fool the operator. It takes thirty seconds for

a helicopter to go from unheard to on scene. It takes & minutes to get a single fire together and

burning. >hat ill the operator see < craDy person running around trying to light a bunch of

fires.

INve also heard people say that thermal imagers canNt see through a sheet of glass. This is true,

but you are going to look very silly trying to run around ith hat looks to a thermal imager like

a five foot suare mirror in the bush.

>hat about those reflective 5ylar survival blankets

Thats all good. 6ut you do realiDe that drones have hover times of hours and helicopters can

hover out of sound range and still kill you ith cannon or missile. Mour need to stay put for any

length of time is compromised by the risk of being discovered by a direct search utiliDing seep

teams ith dogs.

-o yah there are ays to hunker don, but the trick is to not get Npinned donO. #o you

remember the drones endlessly buDDing over BaDa all night long 5y impression is that it isimpossible to move at night during that kind of surveillance.

In this video the <pache is atching these guys ith Forard Looking Infrared (FLIR). 1otice

they donNt hear the rotors or the gun until its too late. The poor guy at the end sticks his head up

to look for it to his demise.

Mou canNt hide from hat you canNt see or hear. <nd the thermal imaging optics on these

eapons sights are infallible as far as it goes. They already pierce the night hen you think it is

dark all around. 8nless you have one to locate the static OhaloO produced on the turbine blades

of the helo, you are meat for the vultures.

#idnNt 5ythbusters also prove that glass stops 1ightision/FLIR



To different things.

O1ight isionO scopes are a passive image intensification of OvisibleO light. They take hat

appears to us to be lo level light (like the moon and stars, city lights) and magnify that many

thousands of times. They are still seeing OvisibleO light spectrum, not infrared (heat) spectrum.

The terms used to describe the to different technologies are based more on the product thanthe science.

OImage intensifiersO or O-tar LightO refer to magnifying visible light.

OThermal ImagingO or OForard Looking InfraredO (FLIR) are based solely on the Infrared

spectrum (heat).

6oth are OpassiveO hich means relying on e$isting light and heat levels and both are commonly

referred to as Onight visionO.

I didnNt see the 5yth 6usters episode so canNt relate. >atch out hat the media tells you. They

so dis!info all day long about certain sub*ects. -ince these technologies are hat the police and

military use to find you in the dark, the less you kno, the better.

Mes that is the trick. There are tricks. 1o technology is infallible. 1othing is impossible and

thermal imagers are not magic. They have considerable limits/compromises. Mou have fallen for

that propaganda and hat you see in the movies.

?very technology/eapon/surveillance system has itNs place but none is %''S effective in every

situation. Thermal imagers are relatively easy to defeat if you kno ho they ork and hat

they can/cannot see. It is not like the movies and it is not like the perfect scenario e$amples that

are released by the military.



I spend a lot of time looking for ildlife ith my thermal imager. INm thorough, very thorough. I

search at a snailNs pace, even loiter. I have thousands of hours e$perience. I kno very ell ho

to ad*ust the imager no matter the eather, temperature delta rate, terrain, etc.

+eck, I engineer pro*ects around the technology so I kno it inside and out. Met despite that,

animals get past me all of the time, maybe most of the time and they are not even trained.

6y the ay, Flir is the name of the company and Oforard looking infraredO is *ust a term some

yahoo came up ith and it stuck.

Thermal imaging technology is easy to block, Flir corp has the data, but you completely lost me

hen I sa that our borders ere to keep us in the country, ust drive thru the gate, no

problem....

?$cellent. 6ased on that obvious e$perience tell me, hat do you attribute the animals ability to

OsneakO by then

I oned an <1C- rifle scope from ietnam era. ?ve though it as OCassive image

intensificationO ith fibre optic intensifiers, it could see the heat from an e$haust pipe on a car

or a arm engine by reflection off the ground. 1ear infrared I am pretty sure. -till it as

aesome to look around at night. I used to see lasers firing over the valley on some nights. I

think the kind that they measure tectonic movement of mountains ith. 6ut I also sa them hit

the ground from +elicopters and planes that fle over head.



< Odry et suitO, the insulated kind that covers your entire body and keeps you arm in e$treme

cold ater scuba divingenvironments is hat I as referring to. If it keeps your heat in, then it

also makes you invisible to Thermal imagers, Oto some e$tent depending on conditionsO Mou still

have to cover your hands and face. 6ut like any other trick, it has its limitations.

Try filming someone in cold ater and let us kno hat you see.

INve done it many times. -omething une$pected occurs. MouNre the e$pert, you should be able to

tell me hat it is.

For a college course I got to see some video of police thermal imaging. This as the mid to late

:'s so it could be better no, but they had trouble seeing through trees, especially pine trees.

7h, INm *ust condescending to those ho post information that is catigoricly false, claiming it is

fact and thinking that hat they sa on Credator or "-I is hat happens in the real orld

spouting it off to sound all knoledgeable.

>hen something moves in the ater it disrupts the thermal boundary layers and an obvious

thermally contrasting ake or disturbed area is left, even if the person/animal is belo the

surface. 7perators (at least good ones) are trained to recogniDe this. <lso, as soon as you pop

your head up, itNs a bright hot spot in the middle of a (generally) featureless scene.

7f course as alays there are things you can take advantage of. If the observerNs perspective is at

a point here your position is in the reflection of the shore features your thermal image can be

significantly obscured. This is because ater is both emissive and reflective in the thermal

infrared portion of the spectrum. This means that the temperature of ob*ects reflected in the

ater is added to the temperature of the ater itself and so appear much hotter than they

actually are hen vieed directly. 6ecause most shorelines are lined ith trees, the reflected

shore image creates a high temperature, highly mottled scene, acting somehat like camouflage.



#o you kno any tricks for helicopters out of audible range Is there some kind of detector you

can use

I noticed that too on some thermal image footage of a car chase. Mou could see heat sources on

the car but not the driver because he had the indo up. >hen he opened the door to run you

could then see him clearly.

It picks up the temperature of the glass, not hatNs behind it.

There, that asnNt so hard no as it Mah, you have to come up for air. Its a trick. If a

helicopter suddenly appeared overhead you could slip into a river or lake, hatever and hidealong the bank (if there as undergroth). <s long as you had a lot of foliage over the top of

your head or if you breathe ith your mouth *ust above the ater line youi signature is greatly

reduced. In a river or Ourgling brookO the motion of the current ould also help to confuse the

IR sensors in the camera. <nyone ho didnNt kno you ere there might think you ere a small

animal say unless highly trained, or the only e$pert like you.

I sa a car chase on video once and the car as OhotO on the FLIR. It splashed into an aueduct

and disappeared from the camera vie. The operator sitched to visible spectrum and turned

on the spotlight to see ObetterO.

6ecause the foliage is OoverheadO and the light (heat) emanating from your body canNt be seen behind the canopy if it is thick enough. 5aybe the pine needles are the most effective blocking

the heat signature Leaves on trees might have gaps and your signature ould be filtering thru.

Mup, but so does cardboard, styrofoam, a toel, etc, etc, etc. hich are not as heavy, not as

It can not see through most things.

Thermal imaging and image intensifier based night vision is passive (generally). This means that

there is nothing being emitted from the devices, so there is nothing to detect. >hen the laser

designator comes on to give the +ellfire missile something to aim at then you can easily detect

that. MouNll have a fe seconds to find a lot of cover. ThatNs if they use a +ellfire. "aveat there too

Low te%h sol*tions for high te%h t$rann$

< considerable threat to those ho decided to fight back against the -edes as the idespread

usage of night vision and thermal imagers by troops sent to hunt don and capture dissenters

(the -edes called them @enemy combatants). The use of FLIR cameras on aircraft and the

feared predator drones ere especially terrifying to those ho kne very little about ho suchtechnology actually functions.

#avid, an insurgent against -ede governance, as tired of hearing about ho the Credator

#rones ould be the doom of all ho defied the establishment. +e felt that this outlandishperception came more from the fact that the drones had no human passenger, and so, no

potential casualty risk.

The concept of facing don a machine that feels no combat apprehension is certainly disturbing,

but not insurmountable. <t bottom, hat the enemy cannot see, the enemy cannot kill. <nd so,

instead of trying in vain to fight the drones and their thermal / night vision on the terms of the

oppressive military presence, he decided to make their vision advantage irrelevant by studying



IR evasion used in sniper training. Regular night vision relies, in most cases, on the use of an IR

light hich bounces off targets ithin the field of vie. This is often referred to as @<ctive IRA.

Thermal ision reads e$isting IR at a different avelength, usually in heat producing or high IR

producing bodies, called @Cassive IRA. For evading <ctive IR night vision, #avid found that

regular camouflaging methods along ith smoke orked ell. For defeating night vision

altogether, he found that bright IR flashlights and floodlights, and even regular bright lights like

camera flashes, shined directly at the target earer of the night vision device, ould be blinded

for a short period of time, leaving room for escape. Thermal vision evasion as more difficult.

#avid and his team first studied the IR ?missivity Tables of common everyday materials0

.optotherm.com....tnp!instruments.com... <ll ob*ects above the temperature of

absolute Dero release a certain level of electromagnetic radiation, hich thermal imagers pick up

and translate into a visual picture. +iding one’s heat signature is difficult, but not impossible.

The key, as #avid learned through military sniper training manuals and combat analysis, as tomatch his IR signature ith that of his surrounding as much as possible.

+e fashioned a hooded cloak using a material that ould block much of his initial armth, then

lined the inside of it ith emergency space blanket material, hich reflects back around :'S



body heat. The cloak design orked ell because he could easily take don the hood and

unrap himself hen not in immediate danger, alloing the material to cool as he alked. Then

#avid attached local vegetation to the material to help match its IR ?missivity to the

surrounding foliage. This combination reduced his thermal signature drastically. 7verhead

drones could not identify him clearly as a human, if they ere able to see him at all. Bround

forces ere a greater threat, but the element of surprise as still possible for the insurgents ithcloaks. In combat, the tandem dangers of drones overhead and ground forces in pursuit ith

thermal vision made life difficult.

#avid carefully studied field guides to Credator #rone strengths and eaknesses0

info.publicintelligence.net... #avid and his team then utiliDed a special strategy under these

e$treme circumstances called @False IR -ignatureA.

7perating in bad eather gave the freedom fighters an instant advantage. +eavy rain ashed

aay thermal footprints and obscured body heat. Thick cloud cover made image integrity poor.

"ontrary to popular belief, the drones had many donfalls, and their eyes ere limited in

numerous ays. >hen in the middle of combat, here drone surveillance as most dangerous

to lo!tech resistance, multiple fake IR signatures ere created using hatever as available.

#avid used a combination of IR "hemlights and hot burning road flares thron all over the field

to misdirect drone cameras. >ith IR hotspots everyhere, the thermal cameras had no idea

here to focus, let alone hich targets ere real, and hich ere fake. IR strobe light flares

flashed intermittently causing even more confusion, and masked to some e$tent muDDle flash

from firearms. Larger ob*ects could also be faked using pieces of metal heated ith fire, or even

heated metallic balloons arranged in a siDable pattern to mimic a hot running car or tank.

#rones ould Dero in on false targets and unleash missiles, only to aste the e$p

#onNt rap yourself in tinfoil. <nything touching your body ill register a heat signature

eventually.

>hat am I supposed to do ith it, suish it into a ball and thro it at the thermal imager I did

methods. Mou have 17 idea hat you are talking about and I believe you are lying outright.

1ight scopes cost a %'' to several thousand dollars. That I could believe, but he as talking

How To -lo%k IR Infrared Thermal Imaging

< arm body can be detected by the IR (Infrared) heat that it gives off ith thermal imagingeuipment, and provides a difficult challenge to someone or some thing ishing to avoiddetection. Mou may be camouflaged in the best concealment that there is, but you may be highly

visible to thermal imaging from someone ith a IR scope on the ground or that #rone flyingoverheadY This goes the same for any arm or hot euipment that you ish to conceal.

>hat is Infrared (IR) It is light (not visible to the human eye) electromagnetic radiation ithlonger avelengths than visible light, e$tending from the red edge of the visible spectrum. If youcould see the aves, the avelength ould literally be only '.'''3; to '.4 millimeters, or'.''''; inches to '.'% inches. +umans at normal body temperature radiate chiefly at

avelengths around '.'% millimeters, or '.'''; inchesY right in the infrared.

There is no absolute certain ay to defeat infrared, but there are some techniues that makedetection more difficult.

7ne of the most effective methods to block IR is to conceal behind glass. Blass is opaue tothermal imaging. It is not a practical solution though, due to the obvious impracticality ofcarrying around a pane of glass, or constructing your alls and ceiling out of glass

< simple and effective method to block IR is an ordinary Zspace blanket’ or thermal blanket of5ylar foil. The foil ill block the IR heat signature behind it. < problem though, is that hateverit is that you are attempting to conceal, its heat ill either build up inside to an unbearabledegree or it ill escape Zsomehere’, hich ill then be visible to IR imagers. "oncealment forthe most part ill be temporary ithout elaborate mechanisms to disperse the heat signature.



For a uick temporary method of IR concealment, thro a blanket over yourself. < thick oolen blanket ill help defeat thermal imaging. "overing ith a layer of insulation, the heat is blocked(or partially blocked) so that it doesn’t radiate. This is only temporary concealment as the heat

builds beneath the blanket, but it may ork long enough to conceal during a uick TI scan or#rone flyoverY

7ther methods of partially hiding from IR is to conceal by blending in ne$t to other armob*ects like stones or thick alls that may still be holding the heat from the day. The vents in

buildings may be out!floing arm air a source of heat that can help obscure your on thermaloutline. Mou get the ideaY herever there is e$isting natural or man!made heat, you can blendin ith that to help conceal your presence to an IR or thermal imager.

>ear an insulated *acket, insulated pants and a hat. It on’t be %''S but it ill help lessen theheat signature. <gain, the heat ill build and escape through the neck openings and face. Moucould cover your face ith cool mud, hich ill ork temporarily. It’s all pretty much commonsense reduce, disperse, or cover the sources of heat.

1etting ill help somehat, but the holes throughout the ebbing of the net ill reveal some of

the thermal IR heat. 1etting ill help to disperse the heat that may be underneath it as theairflo ill be broken up somehat by the ebbing and ill hide or smear hot spots better thannothing covering them at all. The heat signature ill not be as intense, but spread out more. <ne$ample may be to cover a vehicle that has been running ith netting, or to ear a Bhillie suit.

Cut trees and/or brush beteen you and the suspected IR imager. Trees overhead ill help break up the infrared signature, especially under a heavy canopy of leaves.

< moving heat signature at night is uicker to identify than a stationary one (up to a point).

>hen you are hiding your heat signature (ith a 5ylar space blanket or other means), undersome conditions your signature may look Ztoo cold’ to an IR scan of the area (an e$tra darkoutline, or a Zblack hole’), hich may make you detectable. -urely this is better than otherise,

but keep in mind that the ob*ective is to blend in ith the thermal clutter of the surroundings.

<void open spaces and skylines by day or night.

Thermal Imaging does not perform ell in falling rain.

The problem ith most IR cloaking methods, IR clothing or netting designed to block IR, is thatit ill also block the $ackground IR K creating a black hole of varying degrees. Ideally you ould

ant something that Zcloaks’ or blends your IR signature such that the background scatter at your location is hat the observer sees.

inside a dumpster, body heating the bad guyNs side, he can OseeO the hot spot on the dumpsterNsoutside.

6ut if you are not leaning (heating) against that side, he canNt Osee youO. Mour body heat ill not be detected behind most readily available unholed blinding materials if you are not differentially arming/cooling those materials or alloing your on IR to reflect off of something behind/over you. 68T, if the shielding materials are alien to the surroundings, the materialitself ill probably stand out. -ee belo.

Blass ill not allo your T+?R5<L image to transmit (pass) through same as the dumpsterscenario. The lenses of IR imagers are made of e$otic nonglass materials because of this.

?very piece (cluster) of matter, including gasses, emits IR if it is above <bsolute ]ero (minus;&:.=: degrees F). The armer a body gets, the more IR it ill emit. ?ventually it ill enter the

visible spectrum as it gets Ored hotO.

The surface of a piece of matter is here IR is emitted. <ltering an ob*ectNs surface ill alter therate at hich IR is emitted. -toveblack is a classic e$ample.

5aterials physically different from each other ill likely emit IR at different rates. 68T thedifferences may be very slight.

IR imaging (read #?T?"TI71) depends upon to ob*ects having one or more differences inTemperature, ?missivity/Reflectivity, and <bsorption of the compared ob*ects. For this

application, e can forget about <bsorption, and you should all understand Temperature. 1o,? ^ R _ %''S, thus the moreemissive a surface is, the less reflective.

If to dissimilar ob*ects are at the same temperature, a high ? ill OlookO hotter to an IR imagerthan a lo ?, thus forming an image. 7b*ects ith different Temperatures and the right ?Nscould OlookO the same, thus forming 17 image. To ob*ects ith similar temperatures andsimilar emissivities ill present an unclear, poorly defined image. +erein lies your IR strength.

+ere are some ?missivity values for a fe materials, all in percents, all plus/minus a point or



to. These are for short avelength commercial imagers and may vary slightly for long avelength/long range military/L? euipment. 5ilitary techies should have similar emissivitytables for your euipment.

1o, to apply IR!%'%0 In all of the scenarios belo, remember that your body (or <1MT+I1Babove absolute Dero) emits IR in <LL directions. If there is a reflective ob*ect behind or beside

you, it ill pick up your IR and reflect it like you ere a light bulb. >hichever situation and



methods you use, if you have the opportunity, have an ally check you out from a flank ith your best IR detection euipment. 7r get the flyboys to check you out ith FLIRNs namesake. #o this by day <1# night, as the sun ill do eird (but predictable) things to the differential temps.

The 6?-T ay to protect yourself from IR detection is get behind/under hat is already there,and #71NT change the temperature of it. -ince you obviously have to see and perhaps reach out,

do so through the smallest portal(s) you can handle. Those Oman!siDedO targets detectable at%%'' yards are *ust that ! man!siDed ! not the siDe of your nose and right eye. Remember thatglass reflects some IR (%'' ! :; _ =S), and the sky (space) is cold (approaching <bsolute ]ero),so if your scope is reflecting not sun, but sky, it ill look "7L#. If you have on a scope sunshadethat is hot, the internal IR of the sunshade ill reflect out as +7T.

I believe the BI >oodland 6#8Ns are treated ith an IR emittance reducer. If so, the OclothO ?figure in the table ill change and you have to ad*ust for the folloing discussion. 7r obtainuntreated camo fabric or defeat that treatment (starch, I believe).

The IR reducing treatment makes sense for a situation here the oods is cooler than :9.= F. Ihope the #esert #aylight 6#8Ns are 17T treated, but the nighttime anti!starlight smocks

probably should be. If your 6#8Ns image OcoldO against hot sand, you are *ust as OseenO. I trustthe techies ere aare of this, and have specified correctly. 6ut you need to confirm by lookingthrough your euipment at your buddy against some typical

backgrounds.

It has been reported that OfreshO 6#8Ns do indeed have an IR treatment that fatigues (pun) ithlaundering in ObrightenerO detergents. <s a hunter, I am aare of the 8 problem ith animals

ith good night vision (is it an overabundance of rods, or cones, in the eye) and there aredetergents available via sporting goods stores that do not contain brighteners. If you need tomaintain that 6#8 treatment, you might try that. 6ut again, look at your buddies ith youreuipment.

1o, in sand or vegetation (? _ 3=!9')0 If you +<? to have artificial cover for situations here your clothing ill appro$imate the temperature of the surroundings, you ant to e$pose



matching temperature OstuffO ith a similar ? (around 9'). "over as much of your skin (:3) aspossible ith cloth (9') (remember that I donNt kno the ? for treated 6#8Ns). 6ut alsoremember that seaty cloth in a hot, dry background might look cold due to evaporative cooling.If you are in a hot dry situation, a tented, solid (not net), dry camo fabric applied as a screenmight do the trick for IR. (Remember, same T, similar ?). isual is another problem. Heep theoutlines irregular for both IR and visual. -uare stuff in a curvy orld stands out, no matter the

technology. Fresh local vegetation in front of the screen ill help both.

"amo face paint is CR76<6LM a high emitter, similar to regular paints (:'!:&), and seat(ater!:&) is for sure. Mou really have to keep that face behind something. I donNt kno hat asynthetic ski mask ould have for an ?, but I bet it is belo :3. < plain old cotton tee shirt mask

ould ork, but remember the et/dry/cooling problem.

6lack <1MT+I1B is a good emitter. 6lackened steel barrels, synthetic stocks, and paintedsurfaces (all ?Ns in the :'Ns) should be cloth rapped for IR and visual both. 6lack -><Tuniforms probably have a higher ? than camo. Mou need to test.

#ry rubber boot soles (:;) are nearly as hot as your face ! sock Nem (9').

7ld cut local vegetation ill be drier, thus +7TT?R due to lack of evaporation.

The name of this game is to keep both the ?missivity and the Temperature of the screen andclothing the same as that of the surroundings and keep those portals small.

If you are on bare clay or gravel (49!;') and are orried about aerial observation, dig in. "over



yourself ith almost anything sufficiently rigid and then cover it ith at least a thin but full layerof the local OdirtO. This ill match the ?Ns. 7nce the moisture of the ne cover layer euals themoisture of the surface around you (evaporative cooling), you ill be in decent shape IR ise.Remember that these lo ? materials have a high Reflectivity, so block your on IR fromgetting out from under the cover.

If there is a chance your body heat ill affect the top surface of the dirt cover, use insulatingmaterial beteen you and the bottom of the OroofO to keep it the same temp as the groundaround you. Foam board or sleeping bags ill do that.

The most critical times of day for this hide ould be as the sun changes, because rapidheating/cooling of a thin layer of dirt ill sho up compared to the sloer heating/cooling ofthe intact soil masses. If you can set up in a shaded spot here this ill not occur, you should bein decent shape. If there is no shade, make the cover layer thick to create a heat sinkapproaching that of the surroundings.

If there is no threat of aerial observation, and it is only a frontal threat, a OallO of local dirt ithsmall portals ould be the best bet.

<ny ne fo$hole ill print either hot or cold depending on the season and surface temperature,even if the surrounding soil is bare. The deeper soil temp is probably closer to && F than thesurface.

7n sno (9!9&), build a sno fort or tunnel in and make small portals. Try to dust loose snoto duplicate surface te$ture. Cray for ne sno. If you ore an aluminiDed face shield behind



that sno fort, it ould reflect the OcoldO off of the fort, and cover your hot face. This might be ashiny side application of the space blanket, and could be orth testing. >ater (:&) is your breath

hen it condenses. <nd it is armer than the sno. 7nly thing I can think of to do here is breaththrough a ski mask and let it condense before it fogs up over your screen.

<s to ;spa%e blanket; applications0 there might be some, 68T. If you are using the shiny side

toard you to keep your IR from getting out, remember that the backside of it is probably not agood ? match to the surroundings and it ill heat/cool a lot differently than most natural thingsaround you.

If you are trying to put the shiny side out angled don to reflect the IR ofthe terrain right in front of you, there ould be a %'S reduction in the reflection, more if it castsa shado. If the shiny side is out and up, it ill reflect the cold of outer space (or the heat of the

sun) ! and it is going to look R?<LLM eird to visual and starlight in ?IT+?R caseE I cannotthink of a space blanket application that I ould stake 5M life on.

In an urban situation, you ill have lots of OnormalO IR blockers to get under/behind. ustremember that you are an IR light bulb on the cold surfaces behind you. Mou cannot casually setup back in the room shados of a indoless building anymore. Remember, glass ill 17Tpass through (transmit) your IR image. 68T, glass (:;) has a high emissivity and ill sho itssurface temperature rather ell. If you are near the indo

arming it ith your breath, you ill reveal yourself.

If you had a small barrel portal through an otherise intact glass indo, you ould be IR blocked, but visually seen. < loose pane of glass back in the room shados might be a possibility,

especially for a spotter. If the room is painted (:'!:&) and arm (approaching :9.= F), youmight blend in IR ise. 6ut if there is one

arm indo/room in an OemptyO building, something is amiss. The painted alls behind youmight not reflect your IR really ell, but a metallic light fi$ture might blink every time you turn

your face toard it. The best I can imagine is forget about the OroomO and get behind/undersomething that should be there ! sofas, chairs, drapes, etc. and keep your portal small.



1one of the above "71"?<L5?1T strategies are easy none are guaranteed to make youdisappear to an imager. 6ut they ill all help make you a less vivid IR image, thus lessdetectable. IR imagers may or may not have an ad*ustment to key in the emissivity for scanningand reading temperatures. I doubt military/L? targeting devices ould have that ! you donNtcare hat the actual temp is, you *ust ant to see a picture. 5ilitary/L?7 devices probably havea temperature range ad*ustment to scale up/don according to environment. They probably

have an ad*ustment to set the sensitivity ! the difference in perceived T to go from black to hite(dark green to light green hatever).If this is finely tuned, it is like upping thecontrast on your monitor.

There is one comforting thing to consider0 unless you are in the desert, there are a lot ofdifferent OthingsO around you, each of them ith a slightly different Temperature and ?mittancecombination. If you can make yourself OnearlyO match the most common IR surroundings andthe sensitivity is set very high in order to pick up your small T/? difference, the other guy isseeing a lot more clutter around you, so your image ill be *ust one spot

on the #almatian.

For the Bhillie fans0 < man siDed ad of only burlap and *ute rope at :9.= F plus or minus a fedegrees ill have the same ? all over it. 6ut if there as some leafage from an IR blocking camonet on one shoulder and a splotch of shredded 6#8Ns at the aist and some foreign force camomaterial shredded in there somehere in a cluster, all ell supplemented ith local

veggies, from an IR standpoint it ould look like a pile of dissimilar OstuffO.

If you have gotten this far, perhaps a little #?"?CTI71 is in order to up your advantage.

Remember that O-arge >ILL find something during an inspection, so ya might as ell give himsomething so he ill stop looking.O If you ant to determine if indeed IR detectors are out there,

you might ant to give them a coboy hat to shoot at. I donNt kno hat the ? of a bare BIplastic canteen is, but if you either rapped it ith -cotch 44 electrical tape (:3) from ademo/como kit or sprayed it ith foot poder (:=) from your ruck, and had :9 degree ater(coffee 6ody heat) in it,it ould make a darned good human face (:3) to a distant IR imager.Topped ith a 6#8 hat and moved about on a stick behind some intentionally inadeuatescreening after dark (by somebody else behind that coboyNs large rock), I suspect you ouldsoon kno the targeting capabilities of the opposition ! and alsoacuire a muDDle flash. < piece of most anything armer than the terrain drug remotely throughthe grass at night should get IR attention. ust donNt pull it all the ay to your position. 6ut you



get the idea.

If you ant to *ust give him/them something to orry about, scatter some old tire shreds (:;)around at points distant from your position. They ill look hotter than most surroundings henthey are actually the same temperature. Clus, they ill heat up more during sunlight, and holdtheir temperature for uite a hile into dusk. If you can make them move a bit, so

much the better. If they are behind intentionally poor screens, thus not visually or starlightidentifiable, so much the better. This ould be a great application for decoys specially made forthe purpose ! a visually camoNd, high ? lollipop on a spindly, fle$ible stick.

7ne of the ne IR illumination chemlights ould do something, but I have no e$perience iththem. I suspect one of them tripped off in front of or to the side of your position, yourself in ashado from it, ould blind any thermal imagers looking at you ! like a trip flare ould blind astarlight. 7bviously this ould be a defensive action.

There have been some pretty impressive demonstrations of the capabilities of IR euipment. <nd it is indeed impressive stuff, but it ainNt magic. It can image arm footprints on a cold roof,or a OghostO here you leaned against a cold all and alked aay. 6ut those images fade prettyuickly ! faster than the grass ill spring back up on your trail to a nest.

I believe that if one person takes the time to study and understand the theory of IR systems andapplies it to likely circumstances in his orld and does it better than the other guy does, the firstguy has an ?V"?LL?1T chance of being the inner. That is true for sniping or bidding on a roofinspection. ?ven an unfavorable tilt in sophistication of euipment may be overcome ithintelligent application of ingenuity. <nd it onNt take a lot of formal training. <fter that, it ise$perience behind an imager. In your case, looking at your buddies in drill hides, and correcting

each otherNs errors. I grant you that my OthermacamO is not a military targeting device, but if your life is professionally depending on IR avoidance, I hope you have access to IR theorytraining and support along ith the opportunity to drill ith your on imagers.

If you may be e$posed to a OneO technology, you *ust have to learn it and apply it. Like you didfor visual and starlight. In fact, most of those old rules apply to IR0 Irregular outlines. fresh

vegetation. local materials. etc. The only real ne rule is O-imilar ? ! -imilar TO. 1o, get ith

Evading the Thermal Imagers on the 'rones

+ere is a video I did on ho to be unseen from the peering eyes of the #rones. It is a lesson on

being undetectable by thermal imagers.

Plink to .youtube.com (secure)Q

>hat e$actly am I supposed to be hiding from I *ust donNt think INm gonna be that interesting

or anted for anything by a drone or itNs operator. I *ust barely have any interest in hat INm

doing on a daily basis let alone be that interesting to a drone. Mou all must be top -+TF preppers

and survivalist that are on a bunch of alphabet agencies hit lists. +ave fun craling around in

the mud, brush and sno anyay.

I atched your video ith great interest, since INm alays looking for great ne ideas hich are

also relatively ine$pensive and easy to construct for someone ho is 17T very technically giftedor Ocraft!yO (i.e., 5?EE).

I could envision your OlayersO idea as very logical, although it seems that if it ere to be a form!

fitting garment it ould be difficult to freely move around. Hind of like earing a snosuit.

6ut something on the order of a poncho/blanket/cloak (ith a snap!on hood to cover your

head) might be a very useful item. Mou could use a regular blanket on the inner layer, a space

blanket in the middle, and camo!patterned material for the outside.

6eing practical, I onder ho that space!blanket center ould hold up in the ashing

machineE

6ottom line is space blankets ill defeat thermal but they sho up badly in regular imaging so

you need to cover it ith a layer of camouflage. I think a poncho ould be the best solution as it

can cover you in any situation. Lacking camo find a depression in the ground, cover yourself

ith a thin layer of leaves then put a space blanket on top and finally cover that ith leaves and

oodland debris.

<ny direct contact ith the space blanket ill transfer your body heat through so you must have

a layer beteen you and the blanket. Infrared is another thing to think about so you may ant to

ash your camo poncho in IR ash available at sporting goods stores.

never heard of ir ash hat stores carry it

The ash can be picked up at most any place that carries hunting supplies ! from >almart to the

specialty stores. ItNs relatively ine$pensive.

Mou can also do some searching around the Nnet, and there are also other means to ash ith

that ill assist as ell ! as the store!bought product(s) ill surely run out at some point.



ItNs not IR ash. ItNs 8 ash. The premiss is that animals such as dear can detect or see in the

ultraviolet ave length. There is no such thing as infrared ash.

%. light a big fire

. laugh as their thermal imagers are overhelmed by heat

if a drone can pick up arm bodies in a house, ho about using the foil used for insulating

attics, comes in rolls.

if a drone can pick up arm bodies in a house, ho about using the foil used for insulating

attics, comes in rolls.

a layer of that in the attic ould do the trick, right

or the foil can be used for shelters etc

Thermal cannot see OI1O a house. They can only see the surface temp. For instance, if you ere

in a bo$ thermal could not see inside. +oever, if your body temp heated up the bo$ the bo$ ould then appear to the thermal imager as armer than the surrounding environment. If you

put tinfoil on the inside of the bo$ it ould radiate your body heat back toards you, raising the

temp of the inside of the bo$. 6ut because nothing is %''S reflective some of the heat ould

eventually leach through the tin foil and heat up the bo$.

6T>, that is e$actly hy you find reflective materials in insulation for your house.

I on a thermal imaging device and have tried to defeat it it pointless anything tat seems o

ork is signifigantly degraded over time as heat orks its ay through hatever seems like a

good idea.

the thing that really gets you detected is your breathing it looks like a great plume of heat and

trails behind you like a scarf. you cant hide if if any part of you is in the detectors field of vei

you done unless you are behind a tree or a rock but then youre stuck there if you move its over.

<nd from above ell.....

no i dont kno ho ill ObenefitO but i do kno its time better spent polishing other skills

because you cant hide and be effective

5yth 6usters did this too. They found that using painters plastic (the plastic sheeting you lay on

the floor before you paint) blocks your thermal output. +oever after %'minutes it OleaksO heat.

68-T?#E

6ottom line is space blankets ill defeat thermal but they sho up badly in regular imaging so

you need to cover it ith a layer of camouflage. I think a poncho ould be the best solution as it

<ny direct contact ith the space blanket ill transfer your body heat through so you must have

ash your camo poncho in IR ash available at sporting goods stores.

+o do you take a practical approach to evading drones <s you pointed out, a Othermal drone!

proofO suit is practically impractical. #o other governments/agencies have mechanisms to avoid

thermal cameras

The -<- have a ghille suit although I donNt kno much about it and 6<? systems have

developed an active OcamouflageO for tanks that is basically a big thermal T screen. They can

make tanks look like a number of things, cars, the background. There is a video on this0

Thanks for the support. First, I guess yes, I am a OprepperO. I can thank my day *ob for helping to

develop in me a very useful skill. I spend my days developing plans to secure assets against

threats. It has developed in me an ability to take a look at a situation, any situation, and detect,

then delay or eliminate threats. If you decide to protect an asset, hether it be a person or

property, first you have to identify a threat. Then you can only delay or eliminate a threat. For

instance, if you have a valuable in your home and someone comes to your door. First you have to

identify them as a friend or foe. 7bviously, a friend you may let enter. If you identify the target

as an enemy, you can lock your door and delay a ould be thief, or you can stand guard and

shoot the thief (eliminate). This method of thinking is essential in a survival situation. 5y hole

purpose in investing time in a youtube channel is to teach other like minded individuals ho to

think and react in survival situations. I hope I can convey in the videos this premise.

itNs called a gro tent.you can buy them in hydroponic gro supply stores.it has built in Ir and

other protections.I fig iNd use one to sleep in and take another, cut it up and so it into a set of

clothes to ear/or a hood and poncho type of setup...they range from 4$4 to over

%'$%'Ns...plenty of material to use....

The gro tent probably ont ork. If it does it ould be for a very short time. The outside

fabric ould heat pretty uickly. Remember, the mylar isnNt %''S reflective. The idea behind

to layers of mylar and insulation beteen is that the 78T-I#? layer of fabric has the best

chance at being the closest to the ambient environment.

In a thermal cloak the heat ??1T8<LLM has to go somehere. 5y future tests ill note *ust

ho long you ill have in a thermal cloak. If a thermal cloak is effective enough your body ould

overheat before your signature ould appear.

if you used the cloak to cover your body hile laying on the ground you may also buy yourself

some time as the ground itself ould sink some of the heat. Mou ould have to lay on the grounda really long time for your heat to leach far enough aay to be detected.

guess you need to research gro tents more then,because ; %k hps lights put off a ton of heat,yet

it never leaks that heat out.itNs not made of mylar..

5ud ill not ork. Mour body ill uickly heat up the mud to armer than background

temperature. That trick only orks for <rnold and -ly.



Mour vehicleNs engine, frame, and probably body are made of metal. <s such, it ill reflect radarsignals emitted by satellites, !-T<R- and other reconnaissance aircraft and ground troops.To avoid detection by radar, magnetic tape found in audio and video cassettes may be obtainedand mi$ed into automotive or other paint. The vehicle may then be painted ith this mi$ture.This mi$ture has the effect of scattering radar energy, rendering a much smaller and less

effective return signal. >ith a less effective return signal, your vehicle ill not appear to be hatit is to those searching for you, thus you ill have a good chance of being overlooked.

Red*%ing h*man thermal energ$

6eside your vehicle, you must also take steps to reduce your on thermal energy in an evasivesituation. It is not possible for you to cool your body temperature don to ambient airtemperature. <ny attempt to do so ill induce hypothermia and you may die

In summer months hen air temperatures rise beteen := and %''^ degrees there is very littleto no contrast beteen your bodyNs temperature and itNs surroundings. #uring these conditions

you ill be able to elude thermal imaging devices by camoflauging against detection by eye sight

and traveling in the heat of day. <void shaded oodlands or areas here temperatures ill bereduced and ill provide a contrast beteen your bodyNs heat and surrounding air temperatures.

To elude thermal imaging devices at night and in cooler eather, obtain a metaliDed OspaceO blanket and a ool blanket. Form a hood ith the space blanket over your head and allo therest of the material to drop over your back. >rap the rest of the space blanket around to yourfront forming a poncho. 5ake certain the space blanket fits over your slung rifle and gear. <lsomake certain that a slit is formed in the front of your space blanket poncho to allo you to thrust

your arms through for ork or for firing your rifle.

Fasten the poncho at your throat ith electricianNs tape or duct tape if necessary. This illprevent over 9'S of your bodyNs heat from escaping into the environment and being detected.

To further reduce your heat signature, moisten the ool blanket and form it over the top of yourspace blanket in like manner as your space blanket. This ill act as an evaporative cooler anduickly dissipate escaping body heat, thus further reducing your heat signature.+eat signature can be further reduced by obtaining an e$tra space blanket and cutting it,utiliDing the material to form socks, leggings or mittens. <lso forming a veil over your face ith

your poncho ill help to block a large avenue of heat escape from your facial area.

The above techniue ill reduce your heat signature so that you ill appear to be nothing morethan some mice or rabbits to an enemy observer. "raling upon the ground, lying prone orcurling into a ball ill further confuse your heat signature to an observer. -hould you hear or seethe approach of a helicopter or other aircraft, or ground vehicles, it ould be ise to incorporatesuch tactics in con*unction ith the use of euipment described in this pamphlet.

Individual protection against radar

Mour euipment, such as your rifle or space blanket, ill reflect radar signals, making youdetectable by enemy surveillance utiliDing radar sources from satellites, !-T<R- andreconnaissance aircraft and ground troops.

Radar detection by these sources is highly effective, as demonstrated in the first Bulf ar.



To reduce radar signature, mi$ magnetic tape from audio or video cassette sources ith fabric orcarpenterNs glue and brush liberally into your ool blanket. >ear the blanket ith the magnetictape on the inside of the blanket and over the space blanket, as before. #o not et the blanket

ith the magnetic tape/glue mi$ture. That could tend to rapidly degrade the magnetic tapecontent.

<s a further benefit, the space blanket also has the effect of providing protection against

eapons utiliDing micro!ave and electromagnetic technologies.

8se of euipment by 5ilitia formations

For 5ilitias to maneuver as units, personnel must utiliDe euipment like that described in thispamphlet to elude detection by thermal imaging and radar devices that ill be used by enemyforces. 8nit concentrations ill attract enemy attention and ill invite attack by superior forces.To avoid attacks and ambushes, unit commanders should inspect personnelNs euipment toensure that all personnel utiliDe thermal imaging negating euipment before operations.

In order to further reduce detection of unit siDed maneuvers, it ill also be necessary to spreadformations out rather than to bunch up. >hile spread out in or 4 man teams and all personnel

utiliDing the described euipment, a unit may appear to be a number of randomly spaced miceor rabbit siDed animals foraging in the underbrush.

5uch of the modern night vision devices also utiliDe light amplification technologies, so that it isalays important to camouflage against detection by sight, as ell as detection by infrared, heatand radar. This should be borne in mind hen selecting your ool blanket. < poncho made inghillie fashion ith burlap strips ould act in the same manner as the plain ool blanket andprovide better camoflauge from sight. 6ron or olive drab and green colors and at night, gray ora dark purple tend to hide an individual ell.

The space blanket utiliDed alone ithout the ool blanket ill hide your thermal energy ell, but ill appear to a night vision device to be a hole in the surrounding environment as the metaliDed

material ill not only reflect your bodyNs heat back toard you, but is also cooler than thesurrounding environment. It is best to use the space blanket ith the ool blanket as the ool blanket ill stay closer to your surrounding environmentNs temperature. < blanket of ool orother natural material ill provide protection from thermal energy detection for a short periodof time, but ill eventually arm to the point of radiating more heat than the surroundingenvironment. <lays use the space blanket and ool blanket in con*unction.

7n cool, rainy or damp days it is not necessary to moisten your ool blanket. 5oistening your ool blanket is best done on dry days hen utiliDing cover in oodlands and scrub brush. This ill greatly negate the chance of being spotted by aircraft using FLIR technology. >hen ingrasslands or more open areas, do not moisten your ool blanket. <llo it to reflect the sametemperature as your surroundings, but utiliDe your space blanket underneath to hide your on

body heat.



>ool as chosen as the material of choice for the outer blanket because as natural material ittends to reflect the same thermal energy as the surrounding environment and for itNs practical,utilitarian purpose. >ool drys uickly hen heated by your body and itNs insulating and heatretaining factors are restored by your bodyNs heat uickly, thus making a ool blanket a lifesaving piece of euipment hen staying arm becomes a factor.

8sed underneath the space blanket, the ool blanket can help to build back lost bodytemperature and arm an individual hen desperately needed, making an e$tremely usefule$pedient sleeping bag. 7ther natural materials are not effective at this.

<lays ear the side of your ool blanket that has been coated ith your anti!radar detectionmagnetic tape/glue mi$ture inside against your space blanket. This ill protect the layer oftape/glue from being rubbed off in brush and on the ground as you are evading detection.

5icro!ave eapons are being developed for crod control that emitts micro!aves in a tight beam like a laser. This is used to burn the skin and damage the eyes of those targeted. Mourspace blanket ill dissipate micro!ave beams aay from your body, as long as you are not hiton an e$posed area. It is the same principal as rapping a potato in aluminum foil and placing itin a micro!ave oven."ertain electromagnetic fields can influence the human brain.

>eapons are in development that create electromagnetic fields that induce a sence of apathy,depression, and a state of surrender in the human mind. Mour space blanket is effective innegating such fields, as ell hoever if you notice that such eapons are being deployed, it

ould be prudent to vacate the area, employ a faraday caged electromagnetic safe structure or

ground your space blanket.

Wo*ld a s*rvival blanket help a %riminal to evade dete%tion from a thermal%amera<

I have a survival blanket that claims to reflect back :'S of my radiant body heat and INve alays

ondered0



If a criminal ere to hide under a bush rapped in a survival blanket ould he be able to evade

a police helicopter searching ith a thermal imaging camera

I think because raping your self ith a blanket defuses your heat or it traps heat inside the

blanket. 5eaning for a short period of time before your body heats up your blanket the blanket

stays cold/ neutral avioding bieng semm by the camera. If you kno hat I mean. I think

uilted ould do better.

have a look at this ! around ,;' for the thermal image bit.

They ere testing heat detectors used in burglar alarms so the test is not directly transferable toan ir camera like the police use.

<nd hile mythbusters is one of my fav. shos they donNt alays use complete scientific method

or maybe that part ends up on the cutting room floor.

It might help, but it might also dra attention by creating and abnormal hot or cold spot.

Mes to some degree. The army use similar techniues to avoid detection. Remember hoever

that if the heat isnNt getting out ! your going to get hot.

The neoprene suit did insulate body heat from its surroundings, until the suit itself armed up.

Like the neoprene suit, it only orked until the mud armed up from body heat. <lso, Tory left behind mud tracks hile attempting this.

A heat dete%tor %an be fooled b$ heating the room to bod$ temperat*re7

busted

+eating the room from the ceiling immediately set off the sensor, hile heating the room fromthe ground did not. +oever, the sensor as still sensitive enough to detect the difference

beteen human body temperature and the ambient temperature.

A heat dete%tor %an be fooled b$ wearing a highl$ ins*lated fire proximit$ s*it7

The suit blocked the body heat, preventing the sensor from seeing the earer. +oever a small breach in the suit triggered the sensor hen pointed toards it.

N=!' testing s%anners to reveal %on%ealed g*ns

The technology, similar to infrared imaging, can detect a natural energy knon asterahertD radiation

1?> M7RH 2 1e Mork "ity police say they are testing a ne ay to find concealed guns by using

radiation scanners that can detect people carrying firearms.

1MC# "ommissioner Raymond >. Helly said the ne technology can reveal a firearm concealed under

clothing, the 1e Mork #aily 1es reported >ednesday.

The technology, similar to infrared imaging, can detect a natural energy knon as terahertD radiation

emitted by the human body, Helly said during his -tate of the 1MC# address Tuesday.

6ecause that energy cannot travel through metal, a concealed gun can be detected from the image

captured by the detector, Helly said.

OThis technology has shon a great deal of promise as a ay of detecting eapons ithout a physical

search,O he said.

The technology has been undergoing testing by the 1MC# and the 8.-. #epartment of #efense for the past

three years.

The 1MC# hopes to install the heat!seeking devices on police vehicles in the near future, Helly said.



O>e ant to use ne technology to protect the public and police officers from illegal guns,O he said.

6ut civil libertarians say they orry the scanning devices ill be unable to distinguish beteen a gun and

other harmless metal ob*ects such as an iCod.

If the technology only picks up only fuDDy images of possible guns, civil liberties layer 1orman -iegel

said, it could prompt police to make unarranted stops.

OIt ill make an already aggressive policy of stop, uestion and frisk seem tame,O he said.
