February 24th, 2021 Ring The next generation of Ring’s smart home doorbells is here, with better sound, a bigger field of vision and, most interestingly, radar. The Ring Video Doorbell Pro 2 replaces its immediate predecessor as the flagship of the range, offering new features dubbed 3D Motion Detection and Bird’s Eye View. Both harness the new radar sensor — with a range of up to 30 feet — to better identify and track people approaching your home. The former is designed to make motion detection far more accurate, while the latter uses radar to track a person’s movement across your front yard in real time.
