How to "print" what a camera is viewing in a plane?

Hello

I was wondering how you can “print” (I don’t know what other word to use) what a camera is viewing to a 3d object.

Lets say that I have a hall that contains a security camera. I want to have what that camera is viewing in a plane.

Note that I have a main camera (The one with the character). So it will be like if you stand in front of a tv to see it.

Thanks.

RenderTextures will do this, but they are a Pro-only feature:
