In AXIS OS 10.6 planned for June 2021, we will remove stream specific legacy overlays. This means that it will no longer be possible to create, remove or manipulate legacy overlays via URL options.
The following URL options will be removed:
clock
date
text
textstring
textcolor
textbackgroundcolor
textpos
overlayimage
overlaypos
It will still be possible to use the following values with the "overlays" URL option to filter overlays per stream:
"text" – only text overlays are shown
"image" – only image overlays are shown
"application" – only overlays rendered from ACAP applications are shown
