How do I set up correctly a camera? I've a Scene bought from Internet.

This scene has cameras, but I've set up a new one from the front of the object. 

The problem is that when rendering (F12) It renders from top view (there is a camara from the scene in this position). 

But I needed to render from the front, from the camara named "Camara". 

Before rendering I press "0" to see the Camara's perspective and it is correct, but in rendering Camara changes to another camara from the scene: Camara_4_Sc1.

I've set up my "Camara" in Scene panel: but it renders from top (from camara from scene bought in Internet)



Render from TOP (wrong): Pressing F12 changes Camara to Camara_4_Sc1
Rendering is possible only with an active camera. To do it you select it and press CTRL + Numpad 0 or use the Menu as it is in the comment to make it active.
