Often people buy an infrared camera that is not matched to their needs. The features to consider when purchasing an IR camera are intended use, portability, ergonomics, front and back-end electronics, software compatibility, expandability, ruggedness, technical support, training and finally…cost. The detector needs to match the intended use.
Type and Wavelength
Is the detector cooled or uncooled?
What type of detector materials?
Whatwavelength will be required?
Is the detector sensitive enough to see the slight differences in temperature
sometimes needed for given application?
Does the detector have enough pixels to make the picture I need?
How much signal degradation will I get from using a wider or longer lens?
