Ring

Ring is an American home security company founded in 2013 and acquired by Amazon in 2018 for approximately $1 billion. Ring manufactures video doorbells, security cameras, alarm systems, and smart lighting. The Ring Video Doorbell (from $99) is the product that popularized the smart video doorbell category. Ring's ecosystem includes indoor/outdoor cameras ($49-$199), the Ring Alarm security system ($199-$329 for starter kits), Ring Alarm Pro (with built-in eero router), and the Ring Protect subscription ($3.99-$10/month for cloud video storage and 24/7 professional monitoring). Ring devices integrate deeply with Amazon Alexa, Amazon Echo Show, and Amazon's broader smart home ecosystem. Ring has sold over 10 million devices and has approximately 10 million active subscribers. The Neighbors app — a neighborhood watch social network — connects Ring users to share local crime alerts. Ring has faced privacy controversies around law enforcement data sharing and neighbor feed access.
