Advanced Camera Settings -To optimize the lighting settings according to your
requirements, modify the following settings under Lighting Conditions:
• White balance - the white balancing system in the AXIS 231D/232D can
automatically detect white in the image and intelligently use this as a reference
for other colors.
• Exposure control - this setting is used to adapt to the amount/type of light being
used. Allow slow shutter can be enabled/disabled when the exposure control is
set to Automatic.
• IR cut filter (AXIS 232D only)- when the IR cut filter is set to OFF, the camera will
be able to ‘see’ infrared light, e.g. at night, thus making the image clearer. The
image is shown in black & white when the IR cut filter is off.
Note: If set to Auto, the camera 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.
against e.g. 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.
• Windows 24-bit BMP (full color)
• Windows 4-bit BMP (16 colors)
• OS/2 4-bit BMP (16 colors)
• If the image overlay and text overlay are larger than the video image, no overlay will be displayed. When also using a text
overlay, this will occupy 16 pixels in height and as many in width as the video image. Please consider this when configuring
the overlay image.
• If the overlay is initially positioned so that part of it is outside the video image, it will be relocated so that it appears over the
video image, i.e. the entire image is always displayed.
• The maximum overlay image size supported by the AXIS 231D/232D is the same as the maximum image resolution. See Tech-
nical Specifications, on page 46.
