I see! Something like a button press to move the camera?
In that case you can do this:
In the Get All Actors Of Class you set the Actor Class to the type of your camera, Camera Actor ← if that is what you are using. Then you get a copy of the camera. With this copy you can do what you wish.
If you have multiple cameras, you can use the Get All Actors Of Class with Tag. You then add a tag to the specific camera you wish to get.
If you are still having issues, watch this tutorial: Unreal Engine - 3D Menu Tutorial - YouTube
