About Ring Inc.

The Ring Story If not for my wife, the Ring™ Video Doorbell would not exist. Inventors come up with a lot of bad ideas and she has heard them all. One night I shared my idea for reinventing the doorbell. She loved it! Not just for the obvious convenience but for the security of now being able to safely answer the door from anywhere. She said “This is like caller ID for the front door” I hope that you enjoy the Ring™ Video Doorbell as much as we do, and I look forward to hearing your stories about the product.
