    I'm still playing around with the settings for a LPR camera but this is what you get from 250ft away.
    I am going to mount the camera on a pole tomorrow and do a full on LPR setup video. But it will only be from 50-75ft away (depending where I point it), not 250ft

    No issues with the autofocus issue at higher zooms?

    Anyways, I think i've figured out a solution...

    Yes there is currently an issue with some models at a high zoom not focusing (including this camera sent). Andy is currently looking into this. I didn't put this into the video as the problem can be fixed with a firmware update. Andy has contacted the manufacturer and hopefully we will get a response and a firmware patch for it soon.

    What is the solution that you have found?

    We've been waiting for a firmware fix for over a year..... the Z12 will not focus past about 80-85% zoom

    How about a fix for the day/night switching? That’s the only complaint that I have about this camera.

    This issue is only with the new E model, right? I have the older one and it focuses nicely at 100%.

    It's a problem in both models. There is a thread (that bigredfish was in too) talking about the issue but it was on the non-e model. There are a couple fixes for this camera as a work around:

    A. The reflective tape method (which I havent tried yet)
    B. Keep it in B&W mode to counter the lens shift.

    I'm going to keep experimenting and report my findings

    This weekend I have started it up, after quite a long time(finally finalizing the install) and zoomed out to the max, which is pretty much the end of my block and it looked very clean.
    This issue is only at night, or all the time?
    By the way, I have seen your video, after an hour that you have posted it, and commented about the car headlights to be included, not just a licence plate. Great video by the way. Thanks for all your hard work on all these videos, I will view them all, since I'm setting everything up.
    For a newbie like me, these help out immensely.

    Like two-three houses away. Not good with distances.

    I’m able to be at 100% zoom and switch between color day and B&w night switch by using Dahua sunset sunrise to set manual focus numbers for day and night. The key is disabling auto focus via http api command. I’ll work on a guide.

    Shouldn’t need near full zoom at that range. I’m at 80-85% and capturing at 120ft.

    *Edit: Sorry, my bad, removed video. Here's screen caps at 120ft at 80% zoom

    A still frame would have made it easier, but a good capture especially given the angle and motion. Actually, the angle may help by reducing direct reflection back to the camera.
