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. If the prospect of finding your doorbell transformer, turning off the power and manipulating electrical wiring to set up a smart doorbell is too much for you, some retailers offer installation services. Another option is to hire a licensed electrician to do the work. How Much do Video Doorbells Cost?You can expect to spend between $100 and $250 on a video doorbell, with most units costing around $200.
