FLIR cameras are a thermographic camera so they can detect and record images in the infrared radiation (IR) wavelength of the light spectrum. Infrared radiation wavelengths are part of the nonvisible range along the spectrum 3-12 µm. An advantage of the FLIR Thermal Camera is that it collects data that contains the heat differentiation of all the objects recorded on the image. This can reveal many identifying features that can help make determinations for crop disease or stress.
