You can configure all your IPCs and Intercom in the RTSP so all the IP Cameras will be displayed when you press the “Monitor”, BUT you can only see one live camera stream or video at a time (not all of them simutaneously)
BUT, there is a new feature you can configure the RTSP Cameras steam as ScreenSave, and the GSC3570 will display the camera one by one automatically. Check out the new BETA firmware 126.96.36.199 from Grandstream website.
Hope this helps. If you have further questions, please feel free to open a ticket at HELPDESK and Grandstream Support Engineers will help you.
