Amazon's Ring security business is going airborne.

The "Ring Always Home Cam" has an HD camera attached to a drone.

It flies inside your house when motion is detected or when your Ring alarm is triggered, and streams the video to your smartphone.

If you're worried about privacy, Ring says the camera is blocked when in the docking station, that it can't be controlled manually and it's noisy, so everyone will know when it's transmitting video.

The drone costs $250.
