Why isn't there an integrated camera in my Arlo Audio Doorbell?

The Arlo Audio Doorbell is designed to complement your Arlo camera system. Keeping the doorbell and camera separate lets you combine an Arlo Audio Doorbell with any Arlo wire-free camera of your choice. You also have the freedom to place your Arlo wire-free cameras anywhere around your front door so you can see more than what’s directly in front of your doorbell button.
