2 VR Cameras

Hello,

I'm working on a project using the steam VR 2.0 plugin in unity.
I am trying to have one camera in my scene as the player (headset camera) and then have another camera display to a monitor.
I'm finding that the camera that I don't have attached to the Camera Rig is also rotating. How do I stop the camera not attached to the Camera Rig from rotating along with the Vive Headset.

Thanks
