AXIS 282/AXIS 282A - Video & Image Settings
Overlay image requirements:
Overlay image limitations:
• The maximum overlay image size supported by the AXIS 282/AXIS 282A is the same as
the maximum image resolution. See 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.
