I did more poking around today and was refereed to a few that were cheaper and they looked more impressive.
Maybe I misunderstood what I had read but I was under the impression this camera was good up-to 80ft.
I orginally was at 50ft but the angle wasn't awesome,...I'm at 75ft now, I mocked it up and it honestly looks like a stretch, so I didn't even mount it.
So to answer your question I didn't spend the time tweaking all the settings because it looked like a wasted effort.
I was referred to this unit -
5 MP License Plate Recognition IP Camera 5-50mm Motorized Lens 84 IR LEDs | eBay
I'm going to poke around a little more, good news is I finally got my OpenALPR working - I have no idea why it wasn't working before but it works now and connect temporally to another camera.
