The Arlo Audio Doorbell is an addition to your existing wireless Arlo IP camera system. This doorbell has an integrated microphone and speaker. That way, you can always talk to somebody at your door. Even if you're not at home yourself. You don't need an app for this. When someone rings your bell, you get a phone call. Do you accept the call? You can talk directly to the person on your doorstep. If you're unable to hold a conversation, visitors leave a message that you can listen back to later. You can also easily send a preprogrammed message if you're not interested.
You can only use this doorbell in combination with an existing set of Arlo IP cameras.
