20 AXIS 231D+/232D+ - Configuring the Network Dome Camera
Note that if the AXIS 232D+ is set to Auto, it will automatically switch between
IR cut filter ON and OFF, according to the current lighting conditions. This is only
possible when the iris is set to Auto Iris, and the exposure control is set to
Automatic.
• Backlight compensation - this setting is used to make the subject appear clearer,
e.g. against a bright background.
Image Settings
• Auto focus enabled (default setting).
• Sensitivity - sets the speed of the auto focus. High is used when focusing on
objects that move frequently. Low improves the stability of the focus.
Note:
In certain situations, the white balancing system will not operate effectively. Problems may occur if the
image contains no white color at all, or if the dominant color is not white. In these circumstances, the
white balance may incorrectly be based on another visible color in the image, and colors may become dis-
torted. A pale background picture with reddish or blue foreground objects is very symptomatic of this con-
dition. In such cases it is recommended that a fixed white balance setting is selected.

MPEG-4 Settings
Tools for adjusting the MPEG-4 settings and for controlling the video bit rate.
The MPEG-4 standard provides many different coding tools for various applications in
different situations. As most MPEG-4 clients do not support all of these tools, it is usual to
instead define and use subsets for different clients or groups of clients. These settings allow
you to define the type of viewing client to use.
Adjusting the maximum bit rate and setting it to variable or constant is a good way of
controlling the bandwidth used by the MPEG-4 video stream.
