SEATTLE – Ring, the Amazon-owned home security business, introduced a flying camera on Thursday that may excite home-surveillance fans but is almost certain to rankle privacy advocates.

The $250 drone, called Ring Always Home Cam, is among a slew of products unveiled during Amazon’s invitation-only online hardware event.
The drone is small and light, with a high-definition camera, and it can automatically fly on preset paths to specific spots in your home, streaming video to your smartphone of what it sees along the way. Users can set up paths for the drone via a smartphone app, or if the drone detects motion in a part of your home it can fly on its own to that spot and take video of what’s going on. Set for release next year, the drone is meant for indoor use only, and it can be set to work with the Ring Alarm system so that it will fly a preset route if the alarm is triggered.
