Axis video server - Video & image settings
Overlay image requirements:
Overlay image limitations:
• The maximum overlay image size supported by the Axis video server is the same
as the maximum image resolution. See the Technical Specifications,
on page 66.
• When a text overlay is also used, this reduces the amount of space available to
the overlay image. To keep the text readable at lower resolutions, the text overlay
occupies proportionally more of the image at lower resolutions.
• 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. it is always the entire
image that is displayed.
Please see the online help for more information.
Use a Privacy Mask
To use privacy masks to hide different areas of the video image:
1. Select Configurable areas as privacy mask in the drop-down list for
Overlay/Mask Type. New options appear.
2. Enter the (x,y) coordinates of the top left hand corner of the mask, and the height
and width to define the masks’ placement and size.
3. Select the privacy masks’ color: black, grey, white, or red.
4. Click in the box beside Enable to enable one or more of the masks you have
defined and click on Save.
Image Formats Image Size
• Windows 24-bit BMP (full color)
• Windows 4-bit BMP (16 colors)
The height and width of the overlay image in
pixels must be exactly divisible by 4.
