Can FLIR cameras see through walls?

No, FLIR cameras cannot see through walls. They are however, very good at detecting heat signatures. This makes them useful for seeing through smoke, finding people in the dark, and other applications where thermal imaging is useful.

Frequently Asked Question

  1. Can FLIR cameras see through walls?

  2. No, thermal cameras cannot see through walls, at least not like in the movies. Walls are generally thick enough—and insulated enough—to block any infrared radiation from the other side.4 Oct 2019 [1]

  3. Can you hide from a FLIR camera?

  4. A thick woolen blanket is a good variant to defeat the thermal imager. However, it is considered to be a quick temporary method of hiding infrared radiation. To block the heat, you just need to cover yourself with a blanket. Actually, the principle of hiding from a thermal imager is identical to a space blanket. [2]

  5. How much does a FLIR camera cost?

  6. The FLIR E4 Thermal Imager is the first handheld infrared camera under $1,000. With this tool, you have access to 4,800 pixels of valuable information in a cost-effective handheld device_that_s worth looking into! [3]

  7. What’s the difference between infrared and FLIR?

  8. FLIRs make pictures from heat, not visible light. Heat (also called infrared, or thermal, energy) and light are both parts of the electromagnetic spectrum, but a camera that can detect visible light won’t see thermal energy, and vice versa. [4]

  9. Can thermal cameras see into houses?

  10. No, thermal cameras cannot see through walls, at least not like in the movies. Walls are generally thick enough—and insulated enough—to block any infrared radiation from the other side. If you point a thermal camera at a wall, it will detect heat from the wall , not what’s behind it.4 Oct 2019 [5]

  11. Is there a camera that can see through clothes?

  12. Fujifilm have announced that it is releasing a new camera that, among it’s many new features, can see through clothing. The new X-T1 IR has a new function that means it can “see” infrared light which we can’t see with the naked eye.4 Aug 2015 [6]

  13. What camera can see through walls?

  14. The XaverTM800 provides the most comprehensive view behind the wall, and it is also the closest to truly ‘seeing through the wall’. The XaverTM800 is a full 3D imaging device usually used in ISR (Intelligence, Surveillance and Reconnaissance) work.29 Mar 2021 [7]

  15. Do cold blooded animals show up on thermal imaging?

  16. Here, the warmer human hand stands out against the cooler background and the snake. This image also shows why thermal imaging is ineffective on cold-blooded animals, like this snake, since their body temperatures change to the temperature of their environment.20 Mar 2017 [8]

  17. How far can thermal cameras see?

  18. A typical application for thermal imaging is border security, where most threats occur at night. Watchtowers spaced at 4km intervals or more have to be able to detect threats at ranges up to 2km or more to guarantee full coverage of the border.6 Oct 2015 [9]

  19. Can a cell phone camera see infrared?

  20. The cell phone camera is more sensitive to light than human eyes are, so it “sees” the infrared light that is invisible to us.28 Sept 2015 [10]

  21. Can I use my iPhone as an infrared camera?

  22. Can iPhone take infrared photos? The short answer is yes, your iPhone can definitely take infrared photos — with some extra equipment and post-processing techniques. You will need an infrared filter, the ability to shoot in RAW, and the ability to shoot a long exposure.27 Oct 2021 [11]

  23. Can iPhone be used as thermal camera?

  24. Overview. The FLIR ONE for iOS Thermal Imaging Camera, in combination with its free app, transforms your iPhone or iPad into a powerful thermal imager. [12]

  25. What is better night vision or thermal?

  26. Thermal scopes can easily detect animals or moving objects from a long distance whether it is day or night. Their detection is better than night vision scopes. Even in the roughest weather, they can help you see (except in extreme cold).15 Feb 2021 [13]

  27. Why is it called FLIR?

  28. The term FLIR, which stands for “Forward Looking Infrared”, refers to the technology used to create an infrared image of a scene without having to “scan” the scene with a moving sensor, which is what was previously required. [14]


Yes, FLIR cameras can see through walls. However, they can only see through walls that are made of thin materials, such as drywall or plywood. If the wall is made of a thicker material, such as brick or concrete, the camera will not be able to see through it.
