Linking cameras to objects

I have a scene that has a bank of monitors. I'd like each "monitor" to be linked to unity camera. Is this possible?

If you have Unity Pro, yes, you can render each camera to a texture, which is applied to a given monitor.

You can only use render to texture on pro unity but an alternative would be to have a corner of your screen display what's on the camera with Normalized Viewport Rectangle. When you approach your monitor bank you can toggle the camera view in the corner of your screen. It's not ideal but hey, it's an option.
