How To Block Infrared Thermal Imaging? Best Guide

How To Block Infrared Thermal Imaging?


If you are scratching your head trying to find a solution for handheld IR, then you have come to the right place. We all know that thermal imaging cameras may assist us in determining heat sources and leaks, but in the wrong hands, they can become a major intrusion and invasion of privacy issues. This article is to show you, How To Block Infrared Thermal Imaging? and take back control of your privacy.

The technology of thermal imaging has gained popularity with the passage of time because of its uniqueness. It is an extremely powerful tool employed in numerous industries and its use is on the rise due to the fact that its price has fallen significantly even while it becomes more popular. Before going to unveil the strategies and techniques to bypass this technology, let’s figure out the basics of this technology first.


What is Infrared radiation (IR)? 

Infrared radiation is a type of electromagnetic radiation. It has longer wavelengths than light. You can’t see it because your eye is sensitive only to electromagnetic radiation within the visible spectrum.

Infrared thermal imaging or thermal imaging is otherwise known as passive infrared (IR), is a method of using infrared radiation and thermal energy to gather information about objects. It can be used in low visibility environments and can even work in smoke, fog, smog, and haze. It works by detecting the difference in temperature between objects. It is a non-invasive technology that cannot be easily defeated.

Why infrared Thermal imager is so Powerful?

The main reason why thermal imaging cameras are so powerful is that it uses infrared radiation to determine the temperature of an object. This technology is based on the principle of thermography. This means that it measures the infrared radiation emitted by an object and records the temperature of the object based on the amount of radiation emitted.

Infrared radiation is invisible to the naked eye and it is the radiation that we emit in the form of heat. It means any person who has thermal imaging cameras can see your body heat.

Since the radiation emitted by a person is higher than that of the background, the camera can easily distinguish between the person and the background. These cameras are capable of detecting heat from far away and in complete darkness.

This technology can be used to detect hidden threats such as heat leaks and radiation leaks. The thermal imaging camera can detect the heat that is emitted by the internal components of a building, especially in areas where there are no other ways to detect it.

There are certain things from which thermal imaging can’t see through. These things include glass, Concrete, thick wall, metal, and aluminum foil. To block thermal imaging, it is better to hide behind these things. However, if these things are not in the surroundings, you can even hide from thermal imaging. Below are the techniques and strategies to block thermal imaging.


How to hide from Thermal Imaging Cameras?

You can use the techniques and strategies below to hide from thermal imaging cameras. The first thing that you should do is to hide your body heat. There are a few ways that you can do this.

Use Thermal blanket

You can try to mask your heat by covering yourself in a thermal blanket. If you are looking to hide from a thermal imaging camera, you should look for a material that emits very little heat. A thermal blanket is made of a Mylar foil that emits very little heat. It will not be detected by the camera.

A thermal blanket is useful for a number of different reasons. First of all, it can be used as a way to protect yourself when you are in a place that is not comfortable for you. Second, it can be used to keep you warm on a cold night. Finally, it can be used to hide from the curious optics of thermal vision.

The best thing about thermal blankets is that they are very affordable. Thermal Blanket is very compact and lightweight, but this type of blanket can only be used for a short time. A person wearing a thermal blanket may still be detected by an IR camera if he stands in one place for a long time.

Conceal behind a Glass Wall

You can try to hide behind a glass wall. You can use a large window or you can use a window made of tempered glass. This will make it difficult for the camera to detect you. However, the glass may be a problem for you. It will be very hard for you to move around. This type of concealment can be very effective and can conceal you as good as a thick brick wall.

Use Woolen Blanket

If you are looking for a cheap and quick method to hide from a thermal imager, then this is a good option. If you are in a hurry, it will help you avoid getting arrested. But if you are interested in the long-term strategy, you should not use this method.

The principle of the woolen blanket is the same as that of the space/thermal blanket. It restricts the heat inside and can’t allow it to go outside the blanket. But this solution is only for short time, eventually, the heat inside will increase and become the cause of thermal camera detection.

Use Thick Netting

There are two different ways that netting is used. One way is to put it directly above you, and one is to use a thermal tarp that goes around your entire bedding area. Indeed, this will make it hard for the camera to detect you. The main problem with this type of concealment is that you cannot move around easily.

The netting can trap the heat underneath and break it up. Netting material is a good way to break up the thermal signature of your body and equipment underneath. So, this is an effective method for hiding from thermal cameras.

The main advantage of using netting is that it is very cheap. It can be used to conceal you in a number of different places.

It is good to estimate for how long the particular blocking material can block thermal image detection. This will help you to find other solutions to avoid detection.

Use Ghillie suit to diffuse Heat Signature

A ghillie suit is a type of camouflage suit that can help you to conceal yourself. It is a suit that is made of cloth that is very effective in diffusing heat. It can make it very hard for the camera to detect you.

The suit is made of a variety of different materials. It can be made of plastic, wool, and even Gore-Tex. It can be made in a variety of different colors and patterns. It is not just for concealing from thermal cameras, but it can also be used to conceal from other types of surveillance.


Choose a confusing Background

A common way to hide from a thermal imager is to choose a background that is very confusing for the camera. If the background and your body lie at the same temperature, it will be hard for the camera to make sense of the heat signature of your body.

If you are in a city, you can choose a city park that has a lot of trees and plants. This will make it very hard for the camera to make sense of the heat signature of your body.

A confusing background is the best camouflage. Ever wondered how animals can disappear in a forest? They chose the right background. You see, it’s the temperature differences that show up on the images. As different materials radiate heat in different ways, there are many situations where you won’t stand out very much. The most important thing is to stay away from empty spaces and uniform surfaces.

Some More Suggestions

Here there are some more tips to block thermal imaging.

  • Wear an insulated suit. An insulated suit will help lessen your body heat. But after some time when the heat builds, it will search for the open area to come out like from neck and face. But covering your neck and face with cold mud will help to reduce this effect and confuse the camera.
  • While hiding, you may appear as a dark outline or ‘black hole’ to an infrared scan of the area. This will happen when you cover your body with a thermal blanket or a similar material. The body looks too cold to IR scan, leaving a black hole or dark outline in the image. Actually, IR blocking cloaks also hide the heat signatures of the background and you become sometimes detectable to the cameras.
  • Moving body at night time is more visible to the thermal imager than the stationary one.


Final Thought

This article is about the techniques of how to hide from thermal imaging. However, It is not easy to hide from a thermal imaging camera. But if you really want to hide, then you should try to blend in with the surroundings. Avoid places where you are sure to be seen. If you are in a place that is being monitored, then use camouflage and make sure that you are covered. You can hide from thermal cameras by wearing thermal clothing and wearing a thermal blanket. You can use a thermal blanket to help you blend in with the surroundings. You can also use a ghillie suit to help you blend in with the surroundings. Hope this article helped you to hide from thermal imaging.
