Privacy Mask
Privacy masks allow you to mask areas in an image that are prohibited for the viewer. A
3D mask, covers the area regardless of the camera’s angle or zoom position.
To set up a privacy mask:
1. Go to Setup > Video & Image > Privacy Mask and click on the Add button.
2. Move the camera’s view so that the area to be masked is at the center of the image.
3. Use zoom or change the Width and Height values to adjust size of the masked area.
4. Click Save.
Advanced Camera Settings
To optimize the lighting settings according to your requirements, modify the following
settings under Lighting Conditions:
• Color level, Brightness and Sharpness- Find the level that best suits your image
needs by testing.
• 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.
• Exposure area-This setting determines which part of the image will be used to
calculate the exposure.
• IR cut filter - 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.
• Wide dynamic range - Corrects the exposure when the contrast is extreme
• If the image overlay and text overlay are larger
than the video image, no overlay will be dis-
played. When also using a text overlay, this
will occupy 16 pixels in height and as many in
width as the video 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 dis-
played.
• The maximum overlay image size supported by
the AXIS 233D is the same as the maximum
image resolution. See Technical Specifications,
on page 46.
