This wasn't easy since we also needed to connect most of the doorbells to a Heath Zenith SL 2796 02 Basic Series Wired Door Chime and a 16. 5 volt power source to simulate conditions you might face in your home. UsabilityThe best video doorbells are user friendly and come with an array of features that make them convenient while improving security around your door. We examined 20 factors that affect what happens when someone rings the doorbell, accepting a call, in call controls and motion detection settings. We found August Doorbell Cam Pro and Ring Video Doorbell Pro easier to use than other smart doorbells. August's call notification was unique, acting more like a traditional phone call than a standard smartphone notification as with the other six doorbells we tested. The Ring Pro shines in a different way with some of the best motion detection options on the market. In general, the other products were all very easy to use, though RemoBell had fewer options for motion detection, smart home compatibility and was the only video doorbell we tested that must be rung to show live video. You can't look in on a live video stream because the unit goes into hibernation when nobody's around. Video and Audio QualityWhen someone calls at your door, the video doorbell is only as good as the video and audio in the call. For video, we used a video test chart to evaluate clarity in daytime and nighttime conditions, giving scores based on which portions of the chart were easy to read.
