I understand. What did you change to get it set to your preferences? Maybe that would be a starting point for me. I still don't think it will get as good of a picture as the 5231 though.
Location matters, what works for me, may not work for you.
Daytime, I set the contrast to around 55-57, reduce saturation to 42-45, turn on wdr and set to 8 or 9. Set noise reduction daytime to 4-5 or to off.
Night time, set the shutter to manual, speed at 1/60 or 1/100 sec, set the gain to suit, probably 80-90. Adjust the contrast to suit.
Turn down noise reduction as low as you can stand it, probably 35 or so.
It does not have as strong of IR, that's one. So depending on what you are trying to see and at what distance, you may need additional IR.
But, in my case with the cam, and I think
@aristobrat will agree, I think it is every bit as good as the 5231 series.
Make sure it is positioned so it does not have any IR or other reflection on the dome.
