Video Format
—When mounted indoors, the visible camera shutter speed can be
synchronized to the 50 Hz or 60 Hz power used for lighting the scene. If lighting is
connected to 50 Hz power, the PAL setting might provide better video and NTSC
might provide better video under 60 Hz lighting.
Where relevant, changing the settings immediately affects the live visible video images and streams. To

Thermal Image Setup - Thermal Page
In most installations, it is not necessary to change the default settings of the thermal sensor. However, in
some situations, depending on weather, time of day, or scene, modifying one or more parameters can
improve the video stream image. Be aware that, when the conditions change, the parameters might need to
be adjusted again. It is also a good idea to know how to restore the factory default settings (see
).
AGC ROI
The camera's Automatic Gain Control (AGC) algorithm adjusts the thermal video according to the region of
interest (ROI). By default, the ROI is Full screen; the camera's AGC algorithm considers the entire image.
In some cases, defining an ROI that excludes a portion of the screen can improve the image. For example,
the sky is generally very cold. Defining the ROI to exclude the sky might improve contrast in the rest of the
image.
