How do I spawn a Client camera parented to a host Controller

I am currently working on a first person project where there will be only 1 main player and 3 other players will just be observing through 3 different cameras.

Host: CameraMain + Controller Client1: CameraLeft Client2: CameraRight Client3: Camera back

Can anybody help me with this?

Here is my spawn script:

 ServerPlayerManager.js
 
 #pragma strict
  
 function spawnPlayer(player : NetworkPlayer) {
     var ply : PlayerInfo = GameObject.FindObjectOfType(PlayerInfo);
     var go : GameObject = Network.Instantiate(ply.playerPrefab, Vector3.up*3, Quaternion.identity, 0);
 }
