Camera not spawning properly on network

I am trying to spawn a camera for my multiplayer game but the code doesn't work and I'm not sure why, when I run the game and host the server no camera is instantiated in the hierarchy.

Here is the code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.Networking;
 
 public class PlayerMovement : NetworkBehaviour {
 
     private float moveSpeed;
     public GameObject camPrefab;
     private GameObject camObj;
     private Camera cam;
     private Rigidbody2D rb2d;
 
     void Awake()
     {
         if (isLocalPlayer) 
         {
             CmdSetUpCamera ();
         }
         rb2d = gameObject.GetComponent<Rigidbody2D> ();
         moveSpeed = 100.0f;
     }
 
     void Update()
     {
         if (isLocalPlayer) 
         {
             float horizontal = Input.GetAxis ("Horizontal") * moveSpeed;
             float vertical = Input.GetAxis ("Vertical") * moveSpeed;
 
             rb2d.AddForce (Vector2.right * horizontal);
             rb2d.AddForce (Vector2.up * vertical);
 
             Vector3 dir = Input.mousePosition - cam.WorldToScreenPoint (transform.position);
             float angle = Mathf.Atan2 (dir.y, dir.x) * Mathf.Rad2Deg;
             transform.rotation = Quaternion.AngleAxis (angle, Vector3.forward);
         }
     }
 
     [Command]
     void CmdSetUpCamera()
     {
         camObj = (GameObject)Instantiate (camPrefab, transform.position, transform.rotation);
         NetworkServer.Spawn (camObj);
     
         cam = camObj.GetComponent<Camera> ();
     }
 }

both the player prefab and the camera prefab have local player authority checked on their network identity.

Why is the camera not spawning in the hierarchy and how do I fix it?
