I don't have a reference point, but I do have 3 SCO 2080R's that I used to replace other cams with and they are fantastic. Very sharp at night. I think it has something to do with the new W-V DSP chipset
I replaced some vitek cameras with SCO-2080R's
Much better image and detail, but I'm most impressed with the night time images.
So much better than what I had before!
No more blurry edges and ghosting.
