I have been using 2 avtech DVRs for some time now and things have worked well. when viewing in quad view each cam is numbered 1 - 4, when I do a netwrk backup I enter the cam number and view that cam. Now all of a sudden when I backup up cam 1, I get footage from cam 4, the same goes for the other cams, 1 is 4, 2 is 3, 3 is 2, 4 is 1,
Any suggestions please

Same issue on both DVR's?

Mine does this too. Here is a link to another thread regarding this issue.

thanks.
it is quite possible it was due to disconnecting cameras whilst still recording.
All seems fine since I stopped recording, powered off for a few minutes , powered on and started recording again. I didnt do any hardware resets.
