Thermal camera reverse video
You can reverse the polarity of the video image to change the
appearance of objects on-screen.
The reverse video option (video polarity) switches the thermal
image from white-hot (or red-hot if the color mode setting is
active) to black-hot. The difference between white-hot and
black-hot is shown below:
White-hot thermal image.

You may find it useful to experiment with this option to find the
best setting to suit your needs.
