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, tilt or zoom movements.
To always cover a selected part of the monitored area, use a privacy mask. See Privacy Mask on page 24.
How to upload an overlay image
1. Go to Video & Audio > Overlay Image.
2. Click Browse and browse to the file.
3. Click Upload.
4. The Transparency Settings page is now displayed:
- To make a color in the overlay image transparent, select Use transparency and enter the RGB hexadecimal value
for the color. Example: To make white transparent, enter FFFFFF.
For more examples of hexadecimal values, see the online help
- To scale the image automatically, select Scale with resolution. The image will be scaled down to fit the
resolution used by the Axis product.
5. Click Save.
How to include an overlay image
1. Go to Video & Audio > Overlay Image.
2. Select the image to use from the Use overlay image list and click Save.
3. Go to Video & Audio > Video Stream and select the Image tab.
4. Under Overlay Settings, select Include overlay image at the coordinates.
5. To control the image's position, enter the X (horizontal) and Y (vertical) coordinates. The X=0 and Y=0 position is
the top left corner. If a part of the image is positioned outside the video image, the overlay image will be moved so
that the whole image is visible.
6. Click Save.

Privacy Mask

A privacy mask is an area of solid color that prohibits users from viewing parts of the monitored area. Privacy masks cannot be
bypassed via the VAPIX® Application Programming Interface (API).
