Stop camera movement on pause

I have a pause script but which stops the character from moving when the game is paused but I need it to freeze the game camera as well. Can anyone hep?

using UnityEngine;
using UnityEngine.EventSystems;
using System.Collections;

public class PauseManager : MonoBehaviour {
public GameObject pausable;
public Canvas pauseCanvas;

private bool isPaused = false;
private Animator anim;
private Component[] pausableInterfaces;
private Component[] quittableInterfaces;

void Start() 
{
	// PauseManager requires the EventSystem - make sure there is one
	if (FindObjectOfType<EventSystem>() == null)
	{
		var es = new GameObject("EventSystem", typeof(EventSystem));
		es.AddComponent<StandaloneInputModule>();
	}

	pausableInterfaces = pausable.GetComponents (typeof(IPausable));
	quittableInterfaces = pausable.GetComponents (typeof(IQuittable));
	anim = pauseCanvas.GetComponent<Animator> ();

	pauseCanvas.enabled = false;
}

void Update () {
	if (Input.GetKeyDown(KeyCode.Escape))
	{
		if( isPaused ) {
			OnUnPause();
		} else {
			OnPause();
		}
	}

	pauseCanvas.enabled = isPaused;
	anim.SetBool( "IsPaused", isPaused );
}
	
public void OnQuit() {
	Debug.Log ("PauseManager.OnQuit");

	foreach (var quittableComponent in quittableInterfaces) {		
		IQuittable quittableInterface = (IQuittable)quittableComponent;
		if( quittableInterface != null )
			quittableInterface.OnQuit ();
	}		
}

public void OnUnPause() {
	Debug.Log ("PauseManager.OnUnPause");	
	isPaused = false;

	foreach (var pausableComponent in pausableInterfaces) {		
		IPausable pausableInterface = (IPausable)pausableComponent;
		if( pausableInterface != null )
			pausableInterface.OnUnPause ();
	}
}

public void OnPause() {
	Debug.Log ("PauseManager.OnPause");
	isPaused = true;

	foreach (var pausableComponent in pausableInterfaces) {		
		IPausable pausableInterface = (IPausable)pausableComponent;
		if( pausableInterface != null )
			pausableInterface.OnPause ();
	}
}

}

Would have helped more if you posted the actual camera script.
But basically you just have to access your camera script like:

Camera.main.GetComponent<CameraScript>().paused = true;

And in camera script:

([HideInInspector])

public bool paused = false;

void Update()
{
     //nothing here

     if(paused)
          return;

     CamereMoves();
     CameraRotates();
}
