The speaker on the doorbell itself is loud and clear. The app also lets you disable the camera's microphone which turns off audio streaming and recording while still streaming and recording video. Or, you can just disable audio recording, which still lets you hear audio over the livestream. This could be handy if you live on a very loud street and your videos are a racket. Speaking of options, if you subscribe to Nest Aware, you might want to adjust the video resolution down a little. Nest Aware streams continuous video to Nest's servers, and at the top resolution of 1600 x 1200, you could be facing 150GB to 600GB of uploads per month. Nest is up front about this, and suggests reducing the video quality to medium 1152 x 864 or low 512 x 384, or using the schedule feature to turn the camera on and off so that it's not uploading continuously. Smart Home IntegrationBecause Nest is a division of Google, Nest Hello integrates with the Google Assistant but obviously lacks support for Amazon's Alexa and Apple's HomeKit.

You can also ask Google Assistant to cast the doorbell's live video stream to a Chromecast equipped TV. This even worked with my first generation Chromecast, although it took some buffering as all video tends to do on a first gen Chromecast.
