Lpr cam help hopefully last time

The difference in price is that your camera can read/log the plates and the Z12E cannot. But even taking the difference in price and using another solution you can potentially come out cheaper and with more flexibility as the cameras that read plates tend to be a proprietary format. But many of us have seen in the USA that the cameras that actually read plates do a poor job on the USA plates anyway, so we go to a 3rd party.
Then when you get the camera, make sure to look in this subforum to learn all the tweaks you need to make to the Z12E to capture plates.
These are my settings, but you will probably have to do some tweaking based on your field of view.

Got the camera hooked up. This is what I got. Still blurry. What do I need to do? Exposure 1/2000The difference in price is that your camera can read/log the plates and the Z12E cannot.

Dusk and Dawn are always the tough times.
And each camera, even though all Z12, have different chipsets, along with the uniqueness of a field of view.
The first thing to do, if possible, is to have someone park a car in the field of view and then get a good focus on the plate and then adjust some of the other variables.
The other variables like brightness, gamma, etc. have an impact on focus.

Another factor is you haven't listed your state. Just for reference, which state are you or was that plate? A lot of states have gone to 3M printed plates that make LPR very difficult.
That plate looks like it is probably a printed plate? If so, it is even more critical to try to get as close to straight on as you can.

which setting causes 5241E-Z12E blur with even slow motion?
I am still fighting with this camera to get readable plates when the vehicle is moving even 1mph. I will factory reset the camera but don't want to do that until the weekend when I have a few hours (in case something goes wrong). In the mean time, would a few of you share which which firmware...

Poor IR contrast in new Tennessee license plates
I've noticed an issue with nighttime capture of new 2022 Tennessee license plates. The white lettering on a blue background washes out almost completely in IR light, making the plates barely readable. Has anyone encountered similar issues with other plates? I'm wondering if additional IR...
I'm in Texas. Thats max zoom. Thought it would go more since it was 50mm and my last being 12mm. That was right before dark and the first car that passed once I got it up.Dusk and Dawn are always the tough times.

Should I create day and night profiles both in black and white but with different exposure?Dusk and Dawn are always the tough times.

Oh Texas plates are great plates.
@samplenhold has some great LPR going on with the Z12E that is 64mm zoom.
Yes, you should create different day and night profiles with the parameters set up to capture during each event.
Night is usually the more difficult one to dial in so that is why I posted the night settings from mine.
You can experiment with different exposures. Depending on speeds you might get to go as low as 1/500, but most are 1/2000 or 1/1000.

1/250 can get better pic, this camera is doing great as a LPR camera, save a lot if you figure out it under guide.
No, during the day you will need min 1/2000, but probably 1/4000 or 1/10,000
1/250 shutter during the day will be an all white image LOL.
Got it to this at night. Do you think I should go from 1/2000 to 1/1000 to get it better?

Here we go with the updated settings. Looks dim. How can I get it brighter? Can't read the plate

You need to do a few drive bys yourself then. Gonna be a long slog to get this figured out if you only have 1 car/night going by for testing.
