Ring announces an update to its self-explanatory Video Doorbell-- the Video Doorbell 2, with features from the 2016 Video Doorbell Pro (namely 1080p video and motion-detection zones) and a rechargeable battery.
In comparison, the Video Doorbell Pro depends on wired power, making the Video Doorbell 2 an easier to install option. The rechargeable battery is swappable, allowing users to rotate batteries to keep the doorbell powered 24/7 without need for additional wiring. Of course, connection to an existing doorbell system remains an option.
