Controls of a Camera Group 

You can use the group buttons to control the functions of a camera group. A group function allows to switch the lights, to open one or more doors or to make an announcement over several speakers for one or more cameras of the group (regardless of the camera currently shown). In addition, you can right-click on the group buttons and open the context menu to control cameras that are not part of the current group. Before you can this, the cameras have to be set up accordingly, i.e., the cameras need to be connected to door openers/light switches and have to be configured properly.
