Have the original video doorbell but our house has no existing doorbell. I know if I have the app I will be notified if someone rings the bell, but if you don’t have the app are you alerted any way? For example, if someone is watching the pets and staying at the house, they will not have the app. Will they know if someone is at the door?
You could buy a Ring Chime. It’s the easiest way to go.
