Re: Ring Doorbell.
The Blink device rings a notification, on my mobile phone, when anyone approaches one of my cameras.
The Blink keeps the recordings until I wipe them off.
I can be miles away, shopping or on holiday, etc, and can still converse with anyone who triggers the camera.
If a delivery man comes, I can tell him where to put the parcel, from wherever I am.
I even have a record of how he handled the parcel - in case of any damage.
About once a month, I delete any recordings not required.
I'm not trying to sell it, but it works fine for me!
Oh! & the one in the garden records all of the visiting animals which jump in for a look around - deer, cats, squirrels, pikeys, etc
