If a CMS host and its recording servers are communicating via internal IP, you might encounter technical issues receiving video feeds of recording servers over the Internet.
Therefore, when using a web browser to access a central management system from a different domain, you will need a relay service to receive cross-domain video feeds from recording servers. For example, with video relay service enabled, you can watch videos of the recording servers located on your office network even if you are at home. Check the Enable video relay over the Internet automatically box to enable this feature.
