What is the size of the thermal sensor?
Typically, sensors are either 160 x 120 pixels or 320 x 240. The smaller has 19,200 pixels while the larger has 76,800 pixels. A larger sensor gives you much more resolution but costs more. Does camera display a false color thermal image or black and white? Does the camera has user selectable palettes? Can the user create their own palettes? Color palettes are convenient ways for you to see a thermal image. For instance, you may chose to have cold be the color blue, medium yellow and red hot. Or you might want everything black and white with everything over 80 degF red. Or you might want cold to be purple and hot to be yellow. Our cameras have a variety of pre-generated palettes as well as allowing you to create your own and store them on the camera. Can camera save an image to a data card? If you can view a thermal image but not save it, the camera may be of limited use. Can you include a voice annotation with image? Including a voice memo can be very useful when analyzing the picture
