Visible Camera Actors

I have a camera system in my current projects which manages multiple camera actors that follow the player during gameplay. For debugging purposes, I would like to be able to see these cameras in the scene while I am testing the game. This is mostly to see how they follow the character, blend between each other, and move around collisions objects.
Does anyone have any idea on how to set up something like this?
