A smart doorbell camera allows you to see who’s on the other side of your door — even when you aren’t home — so you can weed out guests who don’t come bearing Girl Scout cookies.We recommend the Google Nest Doorbell (Wired, 3rd Gen) because it consistently identifies when motion is happening, accurately distinguishing between people, animals, cars, and packages. An optional subscription enables 24/7 cloud recording.If you don’t have existing doorbell wiring, the TP-Link Tapo D225 Video Doorbell Camera is an easy-to-use model that produces a great image and has several features similar to those of the Nest doorbell. It also includes options to store footage locally or in the cloud.
