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. Every unit we tested produced great results, though the Ring Doorbell Pro had the best video quality overall. To a lesser extent, we also examined effective field of view and whether the video filled the screen. For example, the video doorbells from Ring each have a wide field of view, but the video has a fish eye effect that doesn't fill the whole screen and distorts the image around the edge. While it's not a huge problem for most people, some users, including us, might prefer fullscreen video. For audio quality, we gave pass/fail scores based on how clear and loud a call was on the mobile app as well as the built in speaker on each unit. Although there were small differences in audio quality, we found each unit sufficient for brief conversations with someone at the door.

Ease of UseTo test ease of use, we tracked setup issues and whether we had to contact customer support. Cameras that quickly connected to Wi Fi and had simple setup steps scored well. The Samsung SmartCam HD Pro had the easiest installation. Next, we looked for useful smartphone apps that show recordings, live streaming and basic settings on the first screen you see. The apps from Oco and D Link were the easiest to use. ConnectionOur final test evaluated the Wi Fi connection.
