How to use macbooks as a monitor for iphone camera?

I want to able to record by iphone camera while it's streaming on a mackbook!

You are going to have a bit of a lag but if you want to project your iPhone on your Macbook, you can download a program called Chicken of the VNC. As far as the recording goes, I don't know anything free. Try Screenflow (which gives you a free trial ) or Snapz Pro
