I think bigredfish is talking sense. I looked at the pics and my first thought was not enough IR. You've got them set to manual/100% so they should be at max. Maybe even set IR to auto and try it or go to auto, save, then back to manual and see if that fixes it. Actually putting eyeballs on the cam to see if the lights are on is a great check though. You might even have bird crap on them or something.
