I noticed that you have Camera Rotation set to 180 degrees. This should be set in the camera not in blue iris. This may be causing the record problems.
That is the "Run maintainance" icon for the Database. Right click on the clips and choose Database at the bottom, then choose "Run Maintanace" and the icon will appear.
I had the same problem with authentication. I had to setup another user other than "admin" that had administrative rights, and use that name for authentication.
Try
/admin?camera=x&preset=n
It is much easier.
When using the pos command the positions 0-6 are used for move up,dn left, right, ect. So to got to preset 1 you would use 7, 8 for preset 2.
Try http://10.0.0.124:8080/admin?camera=Dahua_Turret&trigger&user=user&pw=password
I have to have the port number in the command for mine to work.
Also make sure Duhua_Turret is the SHORT camera name.
I had the same problem. I had to uncheck "Get events with PullPointSubscription".
It is in the Video/Network page in camera properties. Go to the Video tab and then "Configure"
I'm not sure why this just started with the latest update. Waiting on a response from Support.
The delays do cause a problem. You might be able to use Zone Crossing in the Motion Setting and Object Detection to keep the camera from moving back, but that would end up getting complicated and involve more cloned cameras. Under Alerts menu there is a Disarm time delay but I'm not sure if that...
The way I handled the problems that you are having, was to control it with a Veraplus controller and PIR motion sensors. The PIR sensors do not seem to react as bad to the camera IRs. This may not work in your case though.
You can play with the Min. duration (Make time) on the camera motion...
