Thermal Camera Image - Raymarine T303 Installation And Operation Instructoins

6.1 Thermal camera image

The thermal camera provides a video image which is shown on
your display.
The video feed provides:
• Thermal image
• Status icons / system information (e.g. camera direction and
docking mode indicators in the example above).
You should take time to familiarize yourself with the thermal image.
This will help you to make the most of your system:
• Consider every object you view in terms of how it will look
"thermally" as opposed to how it looks to your eye. For example
look for changes caused by the heating effect of the sun. These
are particularly evident right after sunset.
• Experiment with white-hot and black-hot (reverse video) modes.
• Experiment by looking for hot objects (such as people) compared
to the colder surroundings.
• Experiment with the camera for daytime viewing. The camera
can provide improved daytime viewing in environments where
traditional video camera performance suffers, such as in shadows
or backlit scenes.
