Yes this is on-premise. The problem is you can not specify the credentials to connect to a server share with the link provided. For instance saving to a NAS device that has a share that is restricted to a user account. You can not specify the user account and password to connect to the share currently in the method https://docs.connectwise.com/ConnectWise_Control_Documentation/On-premises/On-premises_knowledge_base/Change_the_location_of_automatic_video_recordings
With this method the share would have to be wide open to everyone which is not secure.
