Do all of the Dahua PTZ cameras use the focus adjustment manually configured in the presets? Or does the autofocus set the focus when you move between presets?
 
I was just looking through the SD49225T-HN User Manual (downloaded from https://www.dahuasecurity.com/asset...-Web3_0-Operation-Manual-V1_0_0-201805226.pdf) and it appears that you can set the focus when creating a preset. But unless you change the 'Mode' to "Manual" under 'Focus and Zoom', I suspect that it won't have any effect.

Would anyone owning a SD49225T-HN be willing to test and verify that a stored manual focus with presets work?
 
Give this a try
Code: 
http://<ip_address>/cgi-bin/devVideoInput.cgi?action=getFocusStatus

It should ask for a username and password before giving you something like this:

Code: 
status.Focus=0.918015
status.FocusMotorSteps=2720
status.LenAdjustStatus=0
status.Status=Normal
status.Zoom=0.721933
status.ZoomMotorSteps=1345

So you should now be able to use

Code: 
http://<user:pass@ip_address>/cgi-bin/devVideoInput.cgi?action=adjustFocus&focus=0.665636&zoom=0.315000

or if you prefer curl
Code: 
curl --digest -u <user>:<password> -X GET http://<ip_address>/cgi-bin/devVideoInput.cgi?action=getFocusStatus


Edit:
If you're using BlueIris or similar you might be able to set it to run an external script after moving to a preset. I have a similar setup to change my cameras between day/night mode as necessary.

Thank you for the code xdq. I haven't purchased the PTZ camera yet. I was investigating buying the SD49225T-HN for my NRL22 rifle club to use as a spotter scope. Using the camera and a laptop with an external monitor (HDMI TV), would allow everyone to clearly see hits on the small targets (little as 1/4th inch) at range. My concern is the focus time as switching between distances can be moderately quick on a timed course.

Just tried it on mine and it does keep the the right focus on presets when set to manual.
