This is a fairly recent issue with I've been having with Dahua that I've found no solution for. So in essence, there seems to be no way to rename the channels for 3rd party cameras (Herospeed firmware) on either XVR's or NVR's. Every time you attempt to rename the channels either through SmartPSS or the recorder, it always reverts back to the default name, in this case IPC. I've also tried renaming the cameras through the camera's config page, but with no luck. The last known firmware that I can get to save the channel names is from November 2019, so there seems to be some compatibility issue. The cameras I've tested are on Onvif 2.4 and the NVR is Onvif 2.41, could that actually be causing the communication issue?
