Creating a projection from a camera?

Is it possible to create a projection in your game from another camera so that you could make like a security camera or something and watch it on a screen?

If you have Pro, you can use a RenderTexture. It’s a texture produced by an auxiliary camera, so you can “paint” an object with it - a security monitor screen, for instance.

If you don’t have Pro, you can render one camera in a smaller area of your screen while the main camera renders the rest (take a look at http://unity3d.com/support/documentation/Components/class-Camera.html).
