Basic Operation and Configuration
After making configuration changes, it is necessary to save the changes to the server (there is a 
Save button at the bottom of each configuration page). The configuration changes do not take effect 
immediately. Generally, it is also necessary to stop and restart the server for the changes to become 
effective. The server has a configuration that is active and running, and another configuration that is 
saved (and possibly different than the running configuration). 
The message at the bottom of the page indicates the 
saved configuration is different than the active (running) 
configuration, and it is necessary to restart the server. 
It may take up to 20 seconds or more to stop the server, especially when there are multiple video 
streams open. Be patient when stopping the server.
When the server is stopped and the page is refreshed, the status will 
show Server Stopped and the Start button will be enabled.
Click on the Start button to restart the server, and when the page 
refreshes, the status will again show Server Running. The Start button will 
be replaced by a Stop button when the startup procedure has completed.
