I'm working on a script to move my camera using
/ISAPI endpoints. I have set a ptz location for a preset with ID 1 so I can go back to it when I want. I can see the live feed of my camera to keep track of what is happening. When I send the preset command, the camera moves a little to that direction and not fully. I checked if the problem is in my connection, but sometimes it moves on one command, and sometimes not.These are the details of my camera
