I got this because I am hard of hearing and I have an Alexa device in every room in the house. It wasn't hard to wire to the transformer I bought and gives a good view of the door and front yard. Sound pick-up is excellent. It hears the cars coming down the road a good bit before it can see them. It doesn't alert with my dogs, but I could set the sensitivity to do so. Good unit, although you have to pay for any extra services from the Ring company besides the basic answer the door, see who is there. It does have some storage on the device, but if you want to save anything you have to pay for it. When full it overwrites the files.
