How to destroy camera from previous scene?

Hello,
I am working on many scenes. But I have problem just in one of them. In the next scene, I have two Main Cameras, one from current scene and one from previous. How to fix that and delete previous?

The one and only difference is that I have Kinect/FaceTrackingManager added to that scene from I have camera in next.

Probably error comes from here:

Code (csharp):

1. void Start()
2.  
3. {
4.  
5. gestureListener = Camera.main.GetComponent<GestureListener>();
6.  
7. faceTrack = Camera.main.GetComponent<FacetrackingManager>();
8.  
9. mainCam = Camera.main;
10.  
11. StartCoroutine(Play1(mySource1));
12.  
13. }
14.  

 

It's hard to say without seeing a lot more code. I'm assuming it's a single scene load, not an additive load. It seems like the easier solution might be to manually destroy the leftover camera when the new scene loads. That doesn't solve the problem of why it's not destroyed in the first place but it might be a workable answer until you find the root cause.
