It is the IR cut filter making the pink color. Try defaulting that camera as well and adjust the osd settings as I described before. When this happens are the IR LED on? Also is there anything reflective in the area? Pools, wet grass/leaves. Does this happen during specific times during the day?

I have not been able to reset the OSD yet but the issue has now changed. One of the cams still doesn't work at all, I hope to test it tomorrow. The one that was producing the pink color looks fine today. The third one that worked most of the day yesterday with about a 30 minute time where it went pink today has a lot of extra yellow in the image. The parking area has yellow stripes and the car sitting there has a yellow stipe which seems to be over-saturating the camera.
