Camera view of rectangles

Hi

I am new to 3d manipulation esp with helix toolkit.
Am trying to have a camera fixed to a side of rectangle. When the rectangle is rotated or moved, the camera should relatively change it's view. Is there any property that ties the camera to an object or a specific vector of an object? Also, there will be 2 rectangles used as planes intersecting making an 'X' shape from the top view. So there has to be 2 views of one side of each plane and a top view.

I am looking forward to understand a way to make this work.Thanks!
