22AXIS 243SA - Video & image settings

Overlay image requirements:

Image Formats		Image Size
•	Windows 24-bit BMP (full color)	The height and width of the overlay image in
•	Windows 4-bit BMP (16 colors)	pixels must be exactly divisible by 4.

Overlay image limitations:

•The maximum overlay image size supported by AXIS 243SA is the same as the maximum image resolution. See Technical Specifications, on page 69.

•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 is relocated so that it appears over the video image, that is, it is always the entire image that is displayed.

Please see the online help for more information.

Use a Privacy Mask

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.
