These camera objects will help you in a real time presentation because you don’t have to find the best angle at each room in 3D view. The camera objects provide an ideal outlook because their view can be set at eye level, you can also choose the best field of view, they can simulate the view of an average human. This way, each camera object is like a virtual window to the room. It is exactly the same as look around and make photos in a room in the real life.
