how do you enable/disable a camera from the new unity 5 fpscontroller camera for a multiplayer game using PUN

first of all I'm making a multiplayer game using the free PUN. and so to avoid that "bug" where when you got 2 or more players in your game, they follow your every move even though your only controlling 1 game. and the way we remedy this is to manually disable the controller and the camera from the editor and enable them in script so that only that player will be doing the controlling. I've succesfully did the controller but the camera won't enable. I've tried everything.

here is the code I use for the controller.

 GameObject thisPlayer = (GameObject)PhotonNetwork.Instantiate ("FPSController", playerSpawnPoint, Quaternion.identity, 0);
 
 ((MonoBehaviour)thisPlayer.GetComponent ("FirstPersonController")).enabled = true;

// no problems here.

and here are the codes that I tried for the camera.

 thisPlayer.transform.FindChild("Camera").gameObject.SetActive(true);
 
 thisPlayer.GetComponent<Camera> ().enabled = true;
 
 Camera cam = thisPlayer.GetComponent<Camera>();
         cam.enabled = true;
 
 thisPlayer.transform.FindChild(" Main Camera").gameObject.SetActive(true);

//keep in mind that all this scripts are valid(meaning they won't get any error) but again this codes won't work for me as they don't enable the camera.
