Hi Guys, I have a NVR4108HS-8P-4KS2 that I was trying to upgrade to online today. To cut a long one short I had forgotten my nvr password. No problem I thought, so I did a system (Only) reset put in my new password and bingo, no cameras. I'm currently running 2 x IPC-HDW5231R-Z, 2 x IPC-HDW4231EM-AS, 2 x IPC-HDW1320S and 2 x IPC-HDW1320S that I was about to replace with 2 x SD1A203T-GN. I'm getting the message "invalid user name or password" across all 8 cameras on the nvr screen. I'm thinking as I only reset the system the cameras are looking for the old password and therefore giving the message and not displaying. I can't for the life of me remember the old password and I've tried several of my favourites in the hope that the cameras will start working again, but no joy. Does anyone know of a workaround? I don't want to have to dismount and reset 8 cameras at various points around the house but if I need to I will. Hoping for a software solution get out to my problem. Anyone? Cheers and TIA from Scotland where it's 2 degrees C and torrential winds and rain!
