Infrared cameras are a type of thermal imaging camera that uses infrared radiation to create an image. FLIR is a brand of infrared camera. Many people ask if FLIR cameras are accurate. The answer is yes and no. FLIR cameras are accurate when it comes to detecting heat signatures. However, they are not always accurate when it comes to identifying the source of the heat signature.
Frequently Asked Question
Are FLIR cameras accurate?
What does FLIR detect?
Is thermal imaging harmful?
How much does a thermal camera cost?
What is the difference between infrared camera and thermal camera?
Q: How accurate are FLIR thermal cameras in Screen-EST mode? A: FLIR thermal cameras with screening mode can achieve accuracies of Â±0.3Â°C. This meets the U.S. FDA Guidance for Industry and Food and Drug Administration Staff and ISO/TR 13154 specification.13 May 2020 
A FLIR thermal camera can detect tiny differences in heatÂas small as 0.01Â°CÂand display them as shades of grey or with different color palettes. The same image with heat differences displayed in the ironbow and white hot palettes. Everything we encounter in our day-to-day lives gives off thermal energyÂeven ice.16 June 2020 
Is thermal imaging dangerous? No. In fact, our thermal imaging system is a non-contact, non-invasive, passive imaging system that is measuring the heat emitted, or given off, by the human body. 
There are, of course, other thermal imaging cameras on the market. Among them are the $1,195 Flir i3, the $1,495 Flir E5, the $1,769.95 Fluke TiS Thermal Imager, and others. There’s also the purpose-built Black & Decker TLD 100 Thermal Leak Detector, which runs just $28.02 on Amazon.25 Sept 2014 
Active IR systems use short wavelength infrared light to illuminate an area of interest. Some of the infrared energy is reflected back to a camera and interpreted to generate an image. Thermal imaging systems use mid- or long wavelength IR energy. 
Overall, FLIR cameras are pretty accurate when it comes to detecting heat signatures. However, there are a few things that can affect their accuracy, like the distance of the object and the angle of the camera. But as long as you keep those factors in mind, you should be able to get pretty reliable results from your FLIR camera.
