Lighting from last week appears to have taken out 6 of my 8 POE camera ports. The cameras are good because they work in the working ports. I tried to resetting to factory defaults with no luck. Does anyone know how to purchase parts for Reolink? The system board in the DVR would be easy to replace. Reolink does not sell parts. Sucks to have to purchase an entire DVR for a simple board swap.

I don't know how far you want to go, but I took a dvr and camera or two apart, and they seem like pretty off the shelf components.
mouser or digikey or maybe even granger should have the parts you need to take the bad parts off the boards and replace them.

Dang, that sucks... You might try Ebay or ipcamtalk (or other forums) and see if anybody is selling their old stuff or selling the cameras you have as parts-only.
