Advanced Configuration
AGC: The AGC parameters control the overall
brightness and contrast, and determine how the
overall video image appears. The defaults are
suitable for most installations, but in some cases
different settings may provide a more appealing
image, depending on personal preferences.
Note
The Video Analytics default AGC Mode parameters are invoked whenever analytics is enabled. If
AGC parameters are changed while analytics is disabled, they will be invoked whenever analytics
is disabled.
• Brightness (gamma) setting determines the allocation of the 256 "shades of gray" produced by
the AGC. Values above 50 allocate more shades of gray to hotter objects, while values below 50
allocate more shades of gray to lower temperature objects. Range 0 to 100.
Contrast (Max Gain) can be used to increase contrast, especially for scenes with little
•
temperature variation (it may also increase noise due to increased gain). Range 0 to 100.
• Sharpness (DDE Gain) is used to enhance image details and/or suppress fixed pattern noise.
Positive values increase Sharpness, while negative values soften the image and filter fixed
pattern noise. A setting of 20 is neutral and will not have any effect. Range 0 to 100.
AGC Filter (Damping filter) determines how quickly a scene will adjust when a hot object
•
appears (or disappears) within the AGC ROI. A low value causes the AGC to adjust more slowly
when a hot object enters the ROI, resulting in a more gradual transition. Range 0 to 100.
Misc. (Lookup Table): Each Look Up Table (LUT) provides a
different representation of the detected levels of thermal
energy as colors or gray-scale values. White hot and black hot
are gray scale palettes; other tables assign different colors to
different temperatures. These color palettes can be selected
from the Live Video page (refer to
Save Settings: Click Save Settings to store the current
settings as power up defaults. To restore the original settings,
select Factory Defaults.
