The article explains the following aspects of thermal cameras:

  • Range – the entire span of temperatures the camera is calibrated to and capable of measuring
  • Field of View (FOV) – the extent of a scene that the camera will see at any given moment, determined by the camera lens
  • IR Resolution – how many pixels the camera has on the scene
  • Thermal Sensitivity/Noise Equivalent Temperature Difference (NETD) – the smallest temperature difference that can be seen with the camera
  • Focus – fixed, manual or automatic
  • Spectral Range – the range of wavelengths that the sensor in the camera detects

These important specifications need to be considered together when assessing the suitability of a thermal imaging camera for a particular application. For instance, when detecting subtle issues such as moisture, high resolution will only be useful if the camera also has high thermal sensitivity.
