The Ring Video Doorbell [$199] blends convenience, monitoring and security into one sleek, simple and powerful wireless doorbell. Ring streams live audio and video of a home’s front doorstep directly to a smartphone or tablet, enabling homeowners to see and speak with visitors from anywhere in the world. This can prevent break-ins by giving burglars the impression you’re home or enable you to speak with a delivery person at your door and let them know where to leave your package. With built-in motion sensors, Ring can also detect activity and trigger instant mobile alerts, giving users the ability to know what’s happening on their property at all times. Ring installs in minutes with no professional help or tools required and can be accessed through the free Ring app on any iOS or Android device.
