Best out of 3

I have tried 3 different types of doorbells like this one. Video was grainy in others or choppy when you speak. This one is CLEAR video Clear speaking. It was really simple to set up. I had it up and working literally in probably 3 minutes if that and that including the download of the application. I really like that it came with a memory card so I didn’t have to worry about which one is compatible. I already had a door chime and after multiple tries I figured out how to add it so now it rings in the house along with my phone. I can’t express how much better this camera is so much more then the other ones.
