Amazon has acquired Ring, maker of smart home doorbells, cameras, and security systems, according to GeekWire. The company was acquired for more than $1 billion, according to Reuters. The acquisition may be announced later today and was likely made to fuel its fight for the emerging in-home delivery and in-home services market.

Amazon debuted its in-home delivery service Key and Cloud Cam last October. A day earlier, Assa Abloy, owner of one of the world’s largest smart lock companies, acquired August Home, following the start of its in-home delivery trial.

August Home began to experiment with in-home services in 2015 to grant access to repairman or plumbers as well as vacation rental companies like Airbnb and HomeAway.
