The Ring Battery Doorbell would be a much better option for the budget-minded if it wasn't so tied to a subscription plan. On the other hand, it's a great choice for those who are already in the Ring home security ecosystem and paying for a sub, and are looking to add an inexpensive doorbell--especially for secondary doors. Ring offers one of the best smart home security ecosystems on the market, encompassing everything from security cameras and video doorbells to indoor and outdoor lighting, sensors, and professionally monitored home security systems. The flexible Ring Battery Doorbell, introduced late last year, makes for a great introduction to that ecosystem. But that recommendation comes with a caveat: You'll need to sign up for a Ring Home subscription if you want to unlock all this product's features--and that includes the ability to record video.

Ring has announced a refresh of its popular Battery Doorbell Plus outdoor camera. The Battery Doorbell Pro is an upgrade in nearly every way, as is usually the case when companies slap "Pro" at the end of a name. Ring says this new model is its "most advanced battery powered doorbell" ever and that it's packed with features that exceed even its wired doorbells. It boasts radar-powered 3D motion detection, which was also included with the company's Stick Up Cam Pro. Otherwise called "Bird's Eye View", this technology tracks an object's path through the camera's field of view so you can monitor where visitors are going and the route they took to get there.
