Today Amazon held its annual Devices and Services event, debuting its next generation of products. While Amazon isn't live streaming the event, we're on the floor sharing everything it announces in our live blog, including a slew of new Ring products and features. Take Ring's Retinal Vision, rolling out across its new line of 2K and 4K doorbells and cameras. It offers back-side illumination sensors and 10x zoom for clear vision, even in low light. Ring pairs these features with custom large aperture lenses that it claims will capture more light and maintain sharpness throughout the frame.Retinal Vision also "optimizes every step of the imaging process with advanced AI tuning," according to Ring. Basically, it will alter your camera's clarity based on its location. Ring will use AI to sample your camera's quality across up to two weeks, multiple times a day. Then, it will do a "final optimization" that should provide the best video for your location. Retinal 4K Vision will be available on the all-new Wired Doorbell Pro, Spotlight Cam Pro, Floodlight Cam Pro and Outdoor Cam Pro. There are also three power over Ethernet devices, Power over Ethernet devices: the Spotlight Cam Pro POE, Outdoor Cam Pro POE and Wired Doorbell Elite. Whereas Retinal 2K Vision is coming to the all-new Indoor Cam Plus and Wired Doorbell Plus. These devices are available to pre-order today. Beyond 2K and 4K retinal techology, Ring is also introducing Alexa+ Greetings, an intelligent doorbell attendant. It will basically do the hard work of talking to strangers for you. Alexa+ can ask why someone is at your door, give them instructions and manage your deliveries. It works hand-in-hand with another new feature called Familiar Faces. This tool allows Ring to recognize your familiar people and let you know exactly who's at your door. It also lets you limit notifications that come from one of their typical routines, separating them from alerts triggered by an unknown person. Alexa+ Greeings and Familiar Faces — both available in December —build on AI-generated descriptions of your alerts, introduced in June. Jamie Siminoff, founder and gave the example text, "A person is walking up the steps with a black dog" and said the descriptions will be "intentionally concise." It lets you know exactly who is coming to the door through text, not just that someone's there. The feature is available for Ring Home Premium subscribers, which costs $20 a month or 200 annually.Then there's Search Party, which makes your outdoor Ring camera into another lookout for lost pets. If one of your nighbors reports their pet missing in the Ring app, your camera can use AI to identify the animal and send you an alert. However, it wont share any images or videos without your permission. It will start working for lost dogs in November, followed by cats and other pets.
