Ring offers a Ring Video Doorbell, a battery-operated, Wi-Fi-enabled, HD video doorbell. The device enables homeowners to see and speak with visitors from anywhere in the world by streaming live audio and video of a home’s front doorstep directly to the free iOS or Android app. With the goal of reducing crime in communities, the Ring Video Doorbell has several features that can deter potential intruders. For example, as soon as the doorbell's built-in motion sensors detect movement, HD video recording begins and mobile alerts are sent to all users. Footage can then be viewed instantly and shared with family, friends and even law enforcement officials.
