Make second non-Ar camera follow Ar object (spectator view)

Hello,
i am trying to implement a spectator view where a second non-ar camera shows the ar objects in a different angle.
Ar object spwans in side view but i want for example a top view of it in the second non-ar camera screen.
The ar objects (between 3 and 5) are created through image targets.
All objects lie relatively close together and the attached image targets don´t move much.
I attached a camera follow script to the non-ar camera and as a target i put the ar camera.
The normal camera has a Depth of 1 and Target eye = None(main display) whereas the ar camera has a depth of -1 and Target eye=both.
It kind of works but i am having problems with offset etc.
