Does the device make a noise so I can hear if someone is ringing the doorbell when my phone is switched off or on silent?

The Device will alert you via sound if the doorbell is pressed. You can also purchase Ring Doorbell Chime and Ring Doorbell Chime Pro to place around your home to sound once the doorbell has been pressed.
