I need to create a security action working like the existant PTZ Priority:
Is there a way to do so with plugin integration ?
No, unfortunately there is currently no support for creating custom security actions/attributes with values beyond a simple True/False permission model.
An example of implementing a custom True/False security action can be found in this forum post: How to hide plugins from showing in Smart Client Tab and Live Tab for specific roles while allowing for others
So functionality similar to the built-in PTZ Priority security attribute, with multiple priority levels, is not currently available for custom security actions.
Very well, thank you for your answer.
