yeah i will have to do that its difficult as im sure will have to use some help by having someone from the house park the car in middle, and then i will have to adjust with laptop at home.
Exactly same as bigredfish.
Here's some settings to get you heading in the right direction. Yours will end up slightly different.
You have chosen the hardest thing to learn and dial in - LPR. It takes me 10+ hours over 2-4 days to dial in an LPR camera.
You're going to need to read up a lot. Walking you through every part will take days and I'm very expensive.

Only difference is I don't have 30fps setting in mine, only goes to 25fps.
I just modified it now to be 1/2000 shutter with gain 40 to 60 to test as I saw that someone had posted in another thread.
You are running a newer model with a different chipset.
I still think you need more zoom.
Drop sharpness down a lot like to 5.
As this thread shows, things like gamma, brightness, contrast, etc. impact focus as well (which most people would not think it would), so we give you our settings to use as a starting point, but every field of view, angle, etc. is different and take in some instances a lot of trial and error to get it to read plates.

The picture below has been cropped but otherwise has not been edited, even though it looks like someone used photo-editing software to blur the license plate on the left.
I can't control the cars that drive by, so I manually put an old license plate and circular reflector on the right side of the road to help dial in the settings. The left license plate is on a car that is moving just 1 mile per hour. The camera is at a distance of about 135ft, at a 20-30 degree angle, with IR manually set on full blast.
Normally when something isn't clear due to motion, I think of shutter...

sounds good, will keep at it - i guess what im having a hard time understanding is that others who've posted clear LPR plates are zoomed further out than I am.You are running a newer model with a different chipset.

Ex. this one to which you responded --
I am viewing the videos on Unifi Protect, wondering maybe this is a software thing which as to zoom in and take pictures
I assure you @bigredfish has his LPR camera highly zoomed in.
That video in the thread you linked was not where the LPR came from - that was an overview camera.
This is his overview:
And then the tightly zoomed in LPR got this:
Post your settings, not BRF's settings. Like in high school, show your work.
Two observations:
You are not as zoomed in as BRF's shots. Your plate size is smaller.
I don't think you are getting the full IR reflected.
Attached are the settings. I changed sharpness down to 5 for every night and now reverted back today to higher as I am seeing better results.
I have one video that i just caught of a strange behavior by the driver but what sucks is can't read or makeout the plate. I think it says ERA1 F94.
I'm sharing two videos from tonight one was very clear, unfortunately the other was not where I am taking the guess the license plate says ERA1 F94 after I took a snapshot and inserted into platerecognizer.
Match Iframe interval to frame rate. 30/30
go to 8192 bitrate
That looks same as the other example you showed.
I think you have set focus on that parked car plate and the actual target vehicles are much closer and not in focus.
Try to get a daytime video and post it so we can see whats going on.
How far from the camera to that moving vehicle?

will do, daytime works out real well.
i am actually going to park next to the car at the near range, so it's visible at the other corner/distance, you are right at night to get some level of focus im using car parked a bit further up.
I have the version 1 of the Z12E, but get great caps when the lens is clean.
For encoding, I use Frame Rates 25/25 and Bit Rate 20480 Kb/S (customized).
For Image I used very little Sharpness (=2) and Gamma = 20.
Exposure uses 1/2000 and Gain range of 60-80. Iris = 35. 3D NR Level = 18 and 2D NR Level = 2.
WB is set to Natural.
