Seems like I could do this at a lower cost using a video camera hooked up to one of my Macs plus some piece of software like iSentry. ... If I were actually worried about people stealing my dairy delivery off the porch, anyway.
The negative comments on this thread seem to all be working on the assumption that the only reason for having a Ring doorbell is to get a video of thefts or to avoid having to walk to the door to see who is outside.
These are some things we have used ours for in the 3 months or so we've had it.
Seeing when the postman has been so we can nip home to pick up the letter we were waiting for.
Speaking to a delivery driver to ask them to take a package to a neighbour.
Letting the window cleaner, when he had come back for payment, that we weren't around for a few days, saving him keeping coming back.
Our son could speak to a friend who knocked on the door to tell him where he was.
Today, my wife who was at a friends close by knew when I got home for lunch and came home to meet me.
Perhaps my favourite so far: When we were on holiday we could go to live view and look at the snow outside our fine door, whilst we sat in the sun with a drink.
Plus others which I can't recall right now.
Some of these are fairly insignificant things, and could be covered in other ways (I could have just texted my wife to say I was home for example), but the sum adds up to a lot.
I'm sure I could do it another way, but this is a very simple and effective solution and I'm happy to pay for it.
I'm not terrified of theft, but it is a possibility, and it's a significant bonus when added to the other features. I do pay for the video storage, as it if a very reasonable amount, and like an insurance policy it has the potential to be of significant value if the worst happens.
As a final point, there was a spate of break ins to garages in our street a few weeks ago. Over the course of a couple of nights, most of the garages around us were broken into. We don't keep anything of value in ours, but it cost some people a significant amount to get the doors repaired. Ours wasn't touched. It isn't covered by the Ring doorbell, and we may have been missed for other reasons, but my suspicion is that the fact that we have a camera on the doorbell was enough of a deterrent, as it suggests that we could have cameras elsewhere as well.
