You can configure RTSP parameters for each server separately. The Global defaults are only used when a new server is added. All of the global parameters are individually configured for each server and are populated with the global default values. Changing the global default values has no impact to an existing RTSP configuration. When a new server is added, it populates the new server parameters.
You can configure SDV settings for RTSP by importing saved configuration data using a JSON file, or by manually entering data.
