Ring Video Doorbell Pro 2 review: Radar delivers a birds-eye view

Who'd have thought that radar would become an increasingly important technology in the smart home? The second-gen Google Nest Hub taps the tech to track your sleep, and now the Ring Video Doorbell Pro 2 is using it for 3D motion detection. Ring's top-of-the-line doorbell camera offers other advanced features, too, but is it enough to justify its $250 price tag--and the subscription you'll need to access them? If you're not familiar with Ring's video doorbells and other home security cameras, you'll get motion and visitor alerts, but you'll only be able to view a live stream of what's happening in front of the camera unless you sign up for a Ring Protect subscription. You can talk to people in front of the camera--using your smartphone or an Echo Show smart display--but you won't be able to see events that occurred in the past. Ring's subscriptions aren't terribly expensive, starting at $3 per camera per month, but they're the only way to get motion-activated recordings that are stored in the cloud, so you can watch them later (you get up to 60 days of history).
