Dialog Board works in three modes:

1. Automated Responses to Events. 
2. View and Evaluate Alarm.
3. View Video (Active camera).

In Automated Responses to Events, the board shows:

1. The last-in event matching the board filtering settings (1, see Configure the Dialog Board).
   

   All of the above mentioned elements of the board are optional. You configure the board to show them.

2. Text message as configured (2).
3. Comments filed (3).  Comments input can be optional or mandatory (as configured). Comments are logged to System Log,  when you click a response button.
4. Response Buttons (4). If you click a response button, the macro starts,  and the board auto-hides (if configured, see Hiding information boards). 

In the third mode, the panel shows video:

1. from the selected camera;
2. from the stand-by camera for the selected camera.
3. from the stand-by camera for the linked camera.

You can select a camera if you click on its tile on a layout, in the Objects panel (see Objects Panel) or on the map (see Working with the Interactive Map).
