In addition to the main display via the HDMI output, you can also assign a secondary display to show live view, call monitor or event monitor via the VGA or composite output. 

• Live view: Specify how many channels to display.
• Call monitor: Set the sequence time and display each channel one by one.
• Event monitor: Display only when an event occurs. You can configure how many more seconds you'd like to see before and after the event, helping you to see how the whole event starts and ends.
