Restricting camera rotation with gyro

Hi,

I have a script for rotating the camera with a mobile device's gyroscope, and that is working pretty good. However, I also want to restrict the amount the camera can rotate in the scene while using this script. What could I do to it to make this happen? Any help would be highly appreciated!

 #pragma strict
 
 var yMinLimit = -180;
 var yMaxLimit = 180;
 // private var y = 0;
  
 function Start()
 {
     //var angles = transform.eulerAngles;
     //y = angles.x;
 }
 function Update () {
     var tiltSides = Input.acceleration.x;
     tiltSides = Mathf.Clamp(tiltSides, yMinLimit, yMaxLimit);
     transform.Rotate(Vector3.up * tiltSides * 1.5);
 }
