About overlay images
An overlay image is a static image superimposed over the video stream. The image, for example a company logo, is first uploaded to
the Axis product and then used to provide extra information or to mask a part of the image.
Image specifications:
• The uploaded image should be a Windows 24-bit BMP image with maximum 250 colors.
• The image width and height, in pixels, must be exactly divisible by four.
• The image cannot be larger than the maximum image resolution.
• If combining text and image overlays, take into consideration that the text overlay occupies 16 or 32 pixels in height
(depending on the resolution) and has the same width as the video image.
Since it is static, the position and size of an overlay image will remain the same regardless of resolution and pan, tilt or zoom
movements.
To always cover a selected part of the monitored area, use a privacy mask. See Privacy Mask on page 22 .

Privacy Mask
A privacy mask is a user-defined area that prevent users from viewing parts of the monitored area. Privacy masks appear as
blocks of solid color or blurred image elements and are applied on the video stream. Privacy masks cannot be bypassed using the
VAPIX® application programming interface (API).
The Privacy Mask List ( Video > Privacy Mask ) shows all the masks that are currently configured in the Axis product and indicates
if they are enabled.
You can add a new mask, re-size the mask with the mouse, choose a color for the mask, and give the mask a name.
For more information, see the online help
Important
Adding many privacy masks may affect the product’s performance.
