Looks like the camera focused on all the green in front in the first image. In the second image it's reversed, all the green growths in front are fuzzy. The API for adjusting focus, triggering auto focus and getting the current focus value is described in section 13 in the Dahua HTTP API for IP version 1.56.

I set my focus here on this page. I set the bar and left it. Hasn't changed day or night same focus. I have the HFW5431E-Z5 though, but it shouldn't be different. At first I was getting out of focus here and there but I'm also using blue iris and had screen controls on in the settings, I disabled all control through blue iris and focus has not changed.
Does the camera refocus when switching between day/night profiles, or switching between color or black/white?
Are you accidentally triggering refocusing when viewing the camera remotely? I'm using Blue Iris and at first I had the PTZ controls enabled which was really annoying whenever I was using the mobile app as I it was too easy to accidentally trigger refocusing from the app every now and then, so I disabled the PTZ controls in Blue Iris.
If the auto-focus is triggered whenever you switch between day/night profiles then maybe playing around with the settings in section 14.5.1 of the HTTP API may work. To be specific, changing the Mode attribute to 4, though I haven't had much success trying to adjust options listed in the HTTP API that weren't already exposed in the Web UI.

I have an IPC-HF5431E-Z5 that I'm going to sell. Decided I need the extra zoom of the Z12 model for my location. Asking $200, shipped to continental US. Anyone here interested?
NOTE that this is the 4MP model.

post in the classifieds section with prefix WTS (want to sell)

better yet flag your other thread and ask a mod to move it.
So comparing to the other available cams:
1. The Z12 has a wider range of zoom available so may be more flexible for placement, right?
2. Is there a turret style coming with similar zooms to the Z5/Z12?
3. What about an LXIR/EXIR version?

Best zoom available turret is the IPC-HDW5231R-Z
2.7mm ~12mm motorized lens
Which with the great starlight performance is why everyone is excited about it

The free version only lets you do one camera at a time. But it's still pretty handy.

Silly question, but what's the default pass for the cam? Just got mine and don't see a pw or paper inside

Got it! Had to login on PC not from phone...
Have you checked the video to see if there's any hints to what's triggering the re-focus? I have only done limited testing of my Z5 for LPR. Waiting for a Z12 to see if I can get a slightly better view. I just recently left the Z5 at my front door for testing, but so far I haven't had any issues like that, though my focal point should be easier for the auto-focus to nail every time. Maybe if you can re-frame the view slightly to get less of the green bushes?
