Advanced Configuration
provide a more appealing image, depending on personal preferences. Be aware the settings that are
optimal at one time may be less optimal a short time later, since conditions such as weather and time
of day affect the image and are constantly changing.
Experiment with different AGC modes to find the settings
that work best for the particular installation (it may be best
to start with the Scene Presets options, see below). It is
always possible to restore the default settings by selecting
the Factory Defaults button at the bottom of the page.
With the Plateau mode, the ITT Mean parameter effects overall brightness, and Max Gain can
generally be used to increase contrast (although it may also increase noise due to gain).
Scene Presets: Each Scene Preset provides a combination
of AGC and DDE parameters that may be preferred for
certain types of conditions. Select a preset that provides an
image that is optimal for the installation. Recall the Scene
preset can also be toggled by selecting the Toggle Scene
Preset button from the Live Video page control panel.
Digital Detail Enhancement (DDE): DDE is an image
processing technique that enhances details by emphasizing
lines and edges.
Flat Field Correction (FFC): The FFC operation can
correct for non-uniform responsiveness within the pixel array.
A shutter activates inside the camera and provides a target of
uniform temperature, allowing the camera to correct for
ambient temperature changes and provide the best possible
image. The camera performs FFC at regular intervals or when
the ambient temperature changes, but can also be performed
as desired and may cause an overall image improvement.

Image freezes momentarily, pg.
2-18.
Misc. (Lookup Table): Each Look Up Table (LUT) provides
a different display of the various detected levels of thermal
energy as either colors or gray-scale values. Look Up Table 1
is white hot and Look Up Table 2 is black hot; the other tables
assign different colors to different temperatures. These color
palettes can also be selected from the Live Video page (refer
to
Toggle Palette, pg.
2-6).
Save Settings
Click the Save Settings button at the bottom of the page to
store the current settings as power up defaults. To restore the
original settings, select the Factory Defaults button and then
click on Save Settings.
