1) Theft deterrent. Not getting your house broken into is more about not being the most attractive target than anything else. Video cameras, motion detector lights, no bushes blocking vision to windows, etc, all make an impact. 2) Seeing who is at the door without potentially having let them know that you're there. In my house, there are glass windows to both sides of the door. I cannot go look through the peep hole without them know I am there. I purchased one after I had several days of a person (people?) ringing my doorbell in between 3 AM and 5 AM, then driving around the neighborhood slowly in their car. I certainly wasn't going to go answer it or announce my presence in case something sketchy was going on. 3) Communicating with someone at the door if you need to. I sleep late on weekends - sometimes I need to sign for a package. With the ring, I can let them know that I'm there and just need to throw on some clothes, rather than them leaving. Or if I'm in the restroom. 4) I want to keep an eye on the front porch while I'm gone, and get alerts on motion detection. I can catch some neighborhood kids being stupid, or something stealing a package, etc etc. 5) If they're leaving a package that isn't signature required, and I'm not home, I can ask them to put it behind the bushes, etc.
