I have a Dahua IPC-T5442T-ZE but can't get the PTZ working. I did go to the PTZ/Control settings in BI and followed some suggestions on this forum but it didn't work. When I select "Network IP" to Amcrest/Dahua the camera first gets blurry when clicking on the +Loop or -Loop in BI. All other "Dahua ..." settings for "Network IP" don't do anything.
