Hi, I found firmware files for my 6200-4e. I have a problem with a Dahua IPC camera HFW1320S. The camera is properly inserted into the home network. NVR recognizes camera, i can add it, nvr show "connected", i can see the preview in the details page, but i don't have video in the main page, only black frame with data and time. Why? Is there a special configuration for this camera?
Thank You.
