Amazon is buying Ring, the smart doorbell maker, in Amazon’s second-largest acquisition ever.

Ring is now being bought for somewhere between $1.2 billion and $1.8 billion, according to sources. The startup had just recently authorized a fundraising round that would have valued the company at about $1 billion. Both companies confirmed the acquisition, which was first reported by GeekWire.
