To be more precise: I did not mean tilting but turning. From the pictures it seems there is a joint between mount and camera which can be adjusted. But in what range?

Unfortunately, I wasn't able to find any additional information on this. The manufacturer only provides the following viewing angles:

Wide: H 109.9°, V 60°, D 127.7°
Zoom: H 35°, V 19.8°, D 40°
