When I connect mobile APP to CMS server, why can't I see all channels connected to that CMS server?
Mobile APP does not currently support CMS function (and we don't have a schedule to support it). Therefore, when you connect mobile APP to CMS, you can only see channels that are local to that CMS server.
However, if you want to use Mobile APP to view channels coming from multiple NVRs, you can use "Favorite" function. This can achieve the function very similar to CMS.
