Can I get network camera direction?

问题

I am selecting a network camera.

It turned out that the network camera is standardized by ONVIF. In the ONVIF standard, PTZ control gives speed and operating time. I want to get the camera orientation (angle).

Can I get the camera orientation with the ONVIF standard?

Furthermore, I want to change the orientation of the camera by giving an orientation (angle). First of all, is there any camera that can feed back the angle of the camera?

You can look at the GetStatus onvif function to get the current position. It doesn't work with all onvif certified cameras for some reason... (I had trouble with Foscam and Amcrest cameras in the past)

You can look at the AbsoluteMove onvif function to set the position of your camera to the absolute values (angle) you want.

Here's the list of all "available" functionalities of onvif. I say "available" because, just like the earlier GetStatus, some cameras will return you an error when calling them for some reason...
