First of all i wil change the power adaptor to another one. Cables are in ground together with another 230v cables and this is unchangeable. Feom this power adaptor are powered two cameras and problem ist only with single. Both are looking ad the same street and cables are together in the ground
 
How do the frame rates differ at all between the 2 cameras?
On that firmware, are there any indoor/outdoor settings that are aimed at anti-aliasing with pulsing light sources?

If you are paralleling along AC voltage you are probably getting a 60 hz signal induced on the cat 5 cables. Maybe you can kill the ac for a test.
