I put a Nest outdoor camera on my house a few years ago. Mostly to test it out as they are for sale everywhere and I figured it would only be a matter of time before I had people asking about them.
Has worked, and continues to work just fine for my needs.
Was easy to install, easy to set up and easy to use.
I have used them along with the Nest Hello doorbell in a few clients homes and had no issues, and happy clients.
Not for everyone, really comes down to what someone's needs are.
