The company on Tuesday unveiled the $250 Ring Drone Cam, a security camera that can fly from room to room, including upstairs, as well as capture footage during the day or at night. When an alarm or sensor on windows, doors and home security devices is triggered, the textbook-sized drone travels a preset path to investigate suspicious activity. Users can also deploy the drone at any time, the company said.

At a demo in New York on Monday, Ring CEO Jamie Siminoff said the drone could be used as a home monitoring tool and as a crime "deterrent" due to the device's built-in LED lights.

"If someone is going around your house at night, and your motion detector goes off on your Ring doorbell, imagine if you see spotlights and something flying across the window," Siminoff said. "You're probably not going to go into that house."

The drone, which can fly up to eight minutes at a time before autonomously returning to its charging dock, has two plastic-encased propellers that emit a loud buzz when it's airborne.

Ring devices have provided Amazon another avenue to grow its presence in the smart home beyond its Echo smart speakers and Eero routers, expanding in a market that Grand View Research estimates will top $200 billion in sales this year. It's equally fertile ground for Amazon rivals Apple and Google.

Ring, which Amazon acquired in 2018 and is known for its doorbells, has been beset with privacy concerns, primarily due to its partnerships with police. Earlier this year, Ring faced renewed scrutiny over a controversial Super Bowl ad touting an AI pet-finding tool called "Search Party." It then canceled an integration with police tech provider Flock Safety, which has also faced widespread backlash over its automated license plate readers.

Ring first previewed its drone, then called the Always Home Cam, in 2020. Siminoff said he chose to hold off on releasing the device until Amazon could perfect the design, sensors and data processing.

The company on Tuesday also debuted the $1,000 Ring Rover Cam. The device repurposes Amazon's Astro home robot, which had a short life as a business device and has seen few upgrades since its 2021 debut, for companies to use to patrol offices, warehouses and other workspaces.
