Hi Felenasoft!
I love the product, we have decided to purchase a bigger license and have at the moment 8 cameras attached. Our only problem is that some of the cameras keep moving their position (via PTZ) such that over time they all look directly downwards. I am pretty sure that it is not the camera (DLink DCS-5020L) but rather Xeoma causing the issue. Xeoma will also lose the PTZ icon on the preview image for a short time, then when it comes back, the camera jerks downwards. Is this a common problem? Is there a way to disable PTZ in Xeoma? Any help would be useful!
