Answer 1

Cameras may opt to use an alternate method for stopping movement. This I found by trial and error and later found the following post that explained it.

https://doc.milestonesys.com/latest/en-US/onvifdriver/why_the_onvif_driver_does.htm

The solution here is to remove this Stop request from the program. When you do need to stop movement, you will need a different strategy: send in x,y values of zero for continuous movement operation.

I also found that the relative and absolute movements are not really supported on my camera. They work, but they work identically to the continuous movement, not as expected

My camera company have been helpful. The bottom line is that you may need their assistance to know exactly what and how they support their device. For example, I cannot turn off auto-focus on mine.
