Hi

My camera is slowly "drifting" and I try to u derstand why.

I have set several "quick navigation" points from where I quickly, manually, can pan the camera to. But after a couple of weeks, the saved camera positions have moved by itself and are not pointing in the same direction anymore. When I reset them, they will after a few weeks once again be different. Why?

Another discovery I've made is that the endpoints of the camera seems to have moved or been restricted. When I try to move the camera in a direction where I used to be able to move it, the app says that the camera has reached its endpoint and can't rotate further. Why?

The camera is positioned in a weather safe area, free from external interference by obstacles and the worst of wind and rain. It is far up so bo one should be able to reach it and manipulate it. 
 

Any recommendations?
