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 InstallationMore than anything else, easy installation relies on what comes in the box with the smart doorbell. We gave higher scores to products that come with printed instructions, screwdrivers, masonry drill bits, levels, battery chargers and extra parts where applicable. Ring is the only company that met all of these requirements, setting a high standard for the competition. We found that it takes between 10 and 20 minutes to install most video doorbells, though it can take longer if you're not experienced with electrical work. In most cases, you only need a screwdriver to install a video doorbell, though you may need to drill some holes beforehand. If you're installing it on a doorframe, make sure there's enough space since video doorbells aren’t as slim as normal doorbell buttons.
