Is this software compatible with the speed dome HIKVISION DS-2DF7286-A? Is it possible to connect this camera to use it in complete mode? Is version 3.5C compatible too?
The only way to see if it's compatible is to test the application. However, they say on the official website that the application is compatible with IP cameras from over 150 manufacturers. Technically, yes, the software should be compatible with your camera, but the only way to check is to test it.
