I successfully upgraded the firmware on the Swann NVR8-7200. Thanks to knowledge and tips from this forum. Also upgraded the Swann cameras 2xx2 with 5.4 successfully. The only issue after the NVR upgrade was inability to input DDNS of the original Swanndvr.net. This was easily accomplished using the Swann Plus software which saved it to NVR. The NVR config does not display the fields but the DDNS works fine. I used the Swann NVR config menu to upgrade from USB flash drive this NVR uses a digicap.mav file downloaded from Hikvision Europe FTP. Many thanks to DemonicHawk.
