Enter
#x
to show the pan position.
Enter
#y
to show the tilt position.

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 you combine a text overlay with and image overlay, the text overlay always takes presidence over the overlay image in
height. A text overlay always stretches across the whole video image which means you cannot shrink the overlay strip to
make room for an image. For information about the different text overlay heights, see
About overlay text .
Since it is static, the position and size of an overlay image remains the same regardless of resolution and pan or tilt movements.
To always cover a selected part of the monitored area, use a privacy mask. See About privacy masks on page 22 .
