Overlay
Overlays are used to provide extra information, for example for forensic video analysis or during product installation and configuration. Overlays are superimposed over the video stream.
An overlay text can display the current date and time, or a text string. When using a text string, modifiers can be used to display information such as the current bit rate or the current frame rate. For information about available modifiers, see File Naming &
Date/Time Formats in the online help 
.
It is also possible to display text when an action rule is triggered, see Using Overlay Text in an Action Rule.

Overlay Image
An overlay image is a static image superimposed over the video stream. The image, for example company logo, is used to provide extra information or to mask a part of the image.
Since it is static, the position and size of an overlay image will remain the same regardless of resolution and Pan/Tilt/Zoom movements. To set up a dynamic mask, which will always mask the specified part of monitored area, see Privacy Mask.
To use an overlay image, the image must first be uploaded to the Axis product:
1.Go to Video > Overlay Image.
2.Click Browse and browse to the file.
