    Installed my Z12 last night and using it with Blue Iris. I'm having trouble being able to macro zoom in small increments using Blue Iris. When I zoom in using Blue Iris, the camera zooms from 0% to around 75% with one short click. Clicking Zoom in button again zooms to 100%. The same thing happens when zooming out. One zoom out click goes from 100% to 75%. A second click goes to 0%. I tried all the Dahua camera models listed in the Blue Iris drop down, but none of them fix the zooming issue. Using the Dahua app in Internet Explorer, I can macro zoom just fine...

    Anyone figure out a setting that resolves the zooming issue with this Z12 and Blue Iris?
    Thanks.

    I had the same issue. Trying to recall how to fix it. In BI adjust the following settings? camera proprties>PTZ/control> Preset positions change Max travel /motion delay (sec) to 1 from 2.

    I was able to fix my zoom issue last night by following using the Find/Inspect Button in BI under that Specific Camera's Video/Configure properties. I left just the Username, Password, and Camera IP while leaving the Port Number Blank.

    Learned the method from this thread:
    Dahua + Blue iris general questions

    I'll give your Max Traval/Motion Delay setting a try as well tonight and see if that makes it even smoother. Thank you!

    I am using the IPC-HFW5231E-Z12 as a LPR and I am finding it loses focus during night.
    Are we able to fix the focus setting on this camera?

    Anyone know how to stop the auto focus?
    It keeps losing focus at night.

    Some guys on the Z5 page made reference to setting the focus manually in the camera UI and to also disable any Zooming capability in Blue Iris if you have zones enabled as they can be triggered on accident easily when remotely using the app. I still need to disable the BI portion to see if this helps resolve the issue. I also suffer from it going out of focus all the time. It is quite annoying...

    No feedback on how to stop auto focus?
    What about the profile management not working?
    I setup a NIght and Day profile to switch at certain times but it always get stuck on my Night profile. Not idea why.
    I also triple checked the time on the camera to make sure the time on the camera wasn't an issue.

    Did you make sure to switch Profile Management to Schedule in the Dahua software? This may be why your camera is not changing Profiles on the set times.

    I haven't figured out a way to make the camera stop focusing automatically. The problem occurs the most in the evening, but can also happen during the day depending on if there are both near and far objects in the frame.

    What I have done is use Domoticz to send commands periodically to manually Focus the camera to my desired settings. I send a Focus command 15 seconds after I send the Day profile command. I also have the Domoticz Timer switch automatically send a manual focus command every few hours after Sunrise.

    Likewise, I send a Focus command 15 seconds after having Domoticz send the Night profile API command. At night, I send a Focus command every hour because the camera likes to autofocus on the nearer trees.

    In Domoticz, I added Hardware/Devices set as Dummy type. I then use the Switches section to add the HTTP codes. Then I use the Timer function on the Switch to issue Day profile command at Sunrise and Night Profile command at Sunset. I added a separate device for each command and switch.

    There are probably easier ways to accomplish what you need, but this seemed to do the trick for me until there's a way to lock Focus in the Dahua firmware. I also found that Focus settings during the Day were not great at Night, so I have a separate HTTP command for Day and Night Focus.

    Get Focus Status:
    http://username:password@<ip>/cgi-bin/devVideoInput.cgi?action= getFocusStatus

    Adjust Focus:
    http://username:password@<ip>/cgi-bin/devVideoInput.cgi?action= adjustFocus&focus=<focus>&zoom=<zoom>

    Day and Night Profile HTTP API:

    Day: Z12 - 0 Switches to Day Profile
    http://username:password@<IP>/cgi-bin/configManager.cgi?action=setConfig&VideoInMode%5B0%5D.Config%5B0%5D=0

    Night: Z12 - 1 Switches to Night Profile
    http://username:password@<IP>/cgi-bin/configManager.cgi?action=setConfig&VideoInMode%5B0%5D.Config%5B0%5D=1

    If using above Day/Night commands, set Profile Management in Dahua Firmware to Full Time.

    Can anyone publish some demo-video of this cam at the daytime and different focusing distances?

    Thanks.

    Thanks - I spent a lot working on this but still no luck.
    I would definitely not recommend this camera with the auto-focus issue.
    I don't understand why we can't just set the focus and it not change on it's own.

    My camera is constantly out of focus.
