Due to the widespread spread of movies and TV series, many people have misunderstandings about infrared thermal imaging, believing that it has an omnipotent penetrating ability and can even penetrate walls.

What is the penetration ability of infrared thermal imaging?

Onick RE60 is a pocket-sized infrared imaging monocular telescope that can be used for outdoor observation and target tracking at night and in low light conditions.

Onick RE60 can clearly display infrared images of the surrounding conditions, helping you see people, objects and animals clearly.

7. Lightweight and portable: small size, one-handed operation, IP66 protection level, 1 meter drop resistance.




1、Can thermal imagers really penetrate walls?

To answer this question, we conducted a wall test. The experimental results show that when a person stands behind a wall, the thermal imager cannot capture the part blocked by the wall, which clearly proves that the thermal imager cannot penetrate the wall to see objects. Therefore, everyone can rest assured that the thermal imager does not have the function of seeing people through walls, thus ensuring our privacy and sense of security in life.

2. So, can the thermal imager penetrate glass?

We also conducted relevant experiments. In the experiment, a person wore transparent glasses and held a mouse pad. Through the thermal imager, it can be clearly seen that the glasses are completely black, which proves that the glass cannot be penetrated. At the same time, due to the heat left by the hand on the mouse pad before, the mouse pad left an obvious palm print. Therefore, we can conclude that the thermal imager cannot penetrate glass either.

3. Can the thermal imager penetrate clothes?

This is also a concern for many users, after all, it involves personal privacy. Through experiments, we found that thermal imagers can't actually penetrate clothes.


4. So, can thermal imagers penetrate paper or water?

Similarly, we conducted relevant tests and the results showed that thermal imagers can't penetrate these two substances either.However, thermal imagers are not useless. It can penetrate certain objects, such as plastic film. When we hold up the film, the thermal imager can clearly see the portrait. In addition, thermal imagers can penetrate thick smoke and fog, allowing us to see objects such as bottles in a smoky environment.

In addition, thermal imagers also perform well in the dark. In the dark of the visible light night, the thermal imager can present a clear thermal image.

In summary, although thermal imagers cannot penetrate materials such as clothes, paper and water, they can penetrate other objects under certain conditions and form images in dark and dark environments, providing strong support for disaster relief and security.
