IPC-HFW5831E-Z5E - Focus reset on reboot

[MicahJames]

Can't seem to find an answer via search so i apologize if this has been covered.

On my IPC-HFW5831E-Z5E, everytime it reboots (from power outage or weekly reboot) the focus will switch to auto instead of the setting i had it fixed at. This is a problem since its an LPR and all the fuzzy video becomes useless at that point. Is there a workaround for this issue (i've already disabled auto reboot weekly) but i can't do anything about power interruptions that reboot. Thanks!

You could run a periodic script to set the focus to your desired setting.

I’ve seen people talk about that on this forum. Is there a post that goes over the “how to” on that?

thanks for the idea

I have attached an (old) API document for Dahua.

BTW, you can interrogate the camera via the API for current focus and zoom settings and use the reported figures in your manual zoom/focus script.
