Amazon unveils home drone security camera

Amazon's indoor drone, the Ring Always Home Cam, available next year, aims to capture video where customers otherwise lack static cameras.

It can show users video where an alarm has gone off, said Amazon Vice President Daniel Rausch.

"It’s super reassuring to be able to get a view inside your home," he said in an interview.

The device only records while flying, Ring said.

The drone camera, which costs $249, represents Amazon's latest push into shoppers' homes, which evolved from package delivery years ago to gadgets that let consumers turn off the lights or stream media by voice command.

Ring devices have garnered criticism from civil liberties advocates such as the San Francisco-based Electronic Frontier Foundation (EFF), which has said the company should end partnerships with police.
