How to trouble shoot my security camera system

hi all. my Dowson security camera system has 12 cameras connected to it. two power supplies are used for the cameras. one is split to four and the other is split to 8. with respect to the 8, the 8 cameras keep jumping from video to blackout and back and only stops if I unplug the 8 cameras and plug them back in one by one. is there a fix for this?
