Thermal camera point mode
Point mode is only applicable to thermal cameras which have
mechanical stabilization.
Enabling point mode only has significance when stabilization
is enabled. Enabling point mode turns off the horizontal (pan)
stabilization while retaining the vertical (tilt) stabilization. This can
be helpful when you want to use the thermal camera as an aide
to navigation and keep the camera pointing in the same position
relative to the vessel as it turns. For example, you may have
stabilization enabled and have set the camera to point straight
ahead relative to the front of the vessel. If the vessel is turned
at a sharp angle under these conditions, the camera sensor will
not follow the direction of the vessel. Enabling point mode keeps
the camera in sync with the vessel direction while maintaining a
stable elevation position. When point mode is enabled, a lock icon
displays. The camera’s azimuth position is now locked to the base.
When you disable point mode, the unlock icon displays momentarily.
The camera always starts up with point mode disabled.

can also enable point mode at any time by following the steps below.

Thermal camera scene presets
Scene presets enable you to quickly select the best image setting
for the current environmental conditions.
During normal operation the thermal camera automatically adjusts
itself to provide a high-contrast image optimized for most conditions.
The Scene presets provide 4 additional settings that may provide
better imagery in certain conditions. The 4 modes are:
Night Running — scene preset mode for night conditions.
Day Running — scene preset mode for daytime
conditions.
Night Docking — scene preset mode for night docking.
Search
— scene preset mode for identifying people or
objects in the water.
Although the preset names indicate their intended use, varying
environmental conditions might make another setting more
preferable. For example, the night running scene preset might also
be useful while in a harbor. You may find it beneficial to experiment
with the different scene presets to discover the best preset to use
for different conditions.
