Try installing the earlier firmware and then perform the factory reset (in that order)
Did that, and some,,
Ok, here is what worked for me, about the color flickering, (not the noise lines - they are still there..)
1: Downgraded to 1.04, no good.
2; Reset to factory settings, no good.
3; Upgraded firmware to 1.05, no good.
4; Factory reset (FW 1.05), configured, and guess what - no color flickering.

Noise lines in night mode still present on all cameras. All 5 of them.

Three 932Ls, and two 930Ls. Should we consider that a "Feature" or an error?
And then there is the falsely advertised framerate...but that is an other thread.

We have a saying in Norway, "Forstå det den som kan.." translates roughly to "Understand it, those who can..."
