The device glows a nice LED color right on the button itself and on the top. For those of you who love to change the look of things, this LED color is fully customizable via the SkyBell HD app so the kiddos in the family like to make it match the current holiday!Picture/Audio QualityThe picture and audio quality on this device far surpasses anything else I have used/tested. The camera is 1080p which compared to past generations of the SkyBell and the Ring HD, this product is so much better. The closest runner up would be the 720p Ring. The picture itself is very impressive, I have showed friends and co workers my porch from the app and they have been blown away. You can even pinch zoom while watching the video.
