It's not quite a simple solution.  First, if you're not planning on
watching the video all day, you'll need a digital recorder designed for
use with IP cameras.  You could build something like that with a Linux
box, but you're probably better off buying a commercial one designed for
the task.  The other part is harder.  Detecting someone approaching the
door requires at least a motion detector of some sort.  Another approach
is something called video analytics, which analyses the scene to detect
motion etc., determines whether it's appropriate and so on.  Again, not
an easy task.
