An overlay text can display the current date and time, or a text string. When using a text string, so-called modifiers can be used to
display information such as the current bit rate or the current frame rate.
It is also possible to display text when an action rule is triggered, see How to include overlay text in an action rule on page 22 .

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 23 .
