Also lets you tell when people approach the door but don't ring, especially if you have some kind of person detection going. My mailman drops stuff on the porch all the time and never bothers to ring the doorbell which is annoying, but I get a little beep and a thumbnail inside from my home automation platform to let me know someone was on the porch. Plus generally having a recording of your front porch area is useful for security. I've been able to pull video recordings of stuff to prove/disprove things happened, for instance when the mailman ran over a bunch of stuff in my front yard and drove off.
