if the heigt of the target exceeds the height of the camera the camera will follow. This worked perfectly, thanks alot!

 var target:Transform;
 
 function Update ()
 {
 if(target.transform.position.y > Camera.main.transform.position.y)
     {
     Camera.main.transform.position.y = target.transform.position.y; 
     }
 }

This is untested so it may contain something wrong but try something like this.

 var target : Transform;
 var height : float;
 var lastheight : float;
 
 function Start ()
 }
     height = target.transform.position.y;
     lastheight = target.transform.position.y;
 }
 
 function Update ()
 {
     height = transform.position.y
 
     if (height > lastheight)
         transform.position.y = height;
 
     lastheight = transform.position.y
 }

This code goes on the camera. You need to drag in the target object in the editor.
