unity3d - how to control the movement of the main Camera in Unity3d

I am trying to make an mobile application that contains AR(Augumented Reality)-Mode using Unity3D. So I have connected my mobile device with my unity3d program, and the camera works fine. But when move the mobile device, the main camera inside unity program does not move the same orbit that the mobile device moves. Does any one know how to change or control the orbit of the main Camera in unity3d?

This could be happening due to a number of reasons. It could be due to non centered pivots, or coordinate systems for example.

Could you please specify which AR system are you using? As a side note, at work we recently had a project involving Unity3d and Metaio and it was a nightmare to bend the system to do what we needed, specially when we needed to do a lot of object positioning based on the local coordinate system.

When you refer to the orbit of the camera, I imagine it could be that the pivot of the camera is somehow offset and the camera is rotating around that offset. Or maybe that the camera is a child of the actual Game Object that is controlled by the AR system, in which case this parent node acts as a pivot to the camera.

In the picture below you can see that the camera is away from that center point and when it rotates it does it based on that center point, in other words the camera always tries to look at that center point and it gives that feeling of "orbiting" when it moves.

Here's the link to the image (I can't post pictures yet on this forum -.- ) https://i.sstatic.net/fIcY2.png
