This particular camera was a returned item and displayed the error "appcore.exe has encountered a serious error and has shutdown" or something like that. After the error appeared, the thermal part of the image never updated. Unfortunately, there appeared to be no way to reload the same version of the firmware in FLIR Tools. What "fixed" the error was deleting all accessible files when the camera was attached to USB. Other than images, this included a file that likely was a database of the captured images. The thought was if it's accessible from the Windows Explorer, surely the camera will recreate it.
A gotcha in thermal images (thermograms) of mixed materials is emissivity of stuff like drywall and shinny metals is quite different. They could be the same temperature but the camera if assuming equal emissivity will report different temperatures. It's possible to correct the error later, since emissivity is a multiplicative factor in the temperature calculation.
Here are a few interesting images as shown in FLIR Tools. In the upper right of the screenshots, the thermal and visible images are shown side-by-side. Some of the images were taken in the dark and those have a solid black visible image.
A door to an unheated room. In the first image, the range is 64F to 70F. There is a decent gap between the bottom of the door and the floor, and a cold draft can be seen as a "wash of purple." The second image is after install a simple fabric wiper on the opposite side of the door. In this "after" image, the temperature range has increased to 68F to 73F and the draft is significantly reduced.
An uninsulated segment of wall above our fireplace that is about 12F colder than the neighboring wall section. It's also easy to see the wall studs and by their thermal bridging.
1/4W resistors dissipating a bit of heat. The FLIR E5 superimposes visible and a thermal images, with the high contrast regions of the visible image enhancing the details of the thermal image. To help with the superimposition, there is a setting in the camera menu to adjust the expected subject distance. The setting ranges from "1ft" to ">10ft." The setting was likely wrong for this image considering the large deviation.
Kitty paw prints on a tile floor. The small transfer of heat from footprints and handprints show up easily.
Water level in the toilet reservoir.
Heat from a hand reflecting off foil backed insulation.
Heat lost through a door's lockset.
Areas of leakage around a door.
