B&G Zeus2 12 - Manual (Page 97)

The FLIR camera source options
The FLIR camera includes both daylight and infrared video sources.
When the infrared source is selected, the following options are available:
Toggle color scheme Cycles through FLIR’s video output color scheme. Each of
these schemes maps a different color to a different
temperature
Toggle polarity Inverts the color scheme.
For example, instead of: White = Hot and Black = Cold, it will
become Black = Hot and White = Cold
The FLIR camera’s home position
You can set the current pan and tilt position as the camera’s home position.
You can later quickly return to this camera position.
