The news reflects Amazon's growing security business since its acquisition of smart doorbell maker Ring in 2018, an effort that's drawn scrutinty from civil liberties advocates. It also 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.

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 company also announced a car device that sounds an alarm when a break-in or bump is detected. It unveiled a vehicle security camera, and the Ring Car Connect software that works with other vehicle cameras for video play back and alerting. Tesla Inc is the first automaker whose models are compatible.

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.

"Amazon and other companies offer a high-speed digital mechanism by which people can make snap judgments about who does, and who does not, belong in their neighborhood, and summon police to confront them," EFF staff wrote in a June blog post.

Ring President Leila Rouhi said in an interview the company will never proactively share videos with law enforcement; users control what to share. Ring's aim is to give peace of mind, she said.

Amazon also announced a cloud-based gaming service called Luna, spherical Echo speakers and features for its voice assistant Alexa, like the ability to delete all prior recordings. Various subscriptions help Amazon monetize the products.

The new devices come as Amazon is working to maintain U.S. market share in smart speakers over rivals Apple Inc and Alphabet Inc's Google.

Amazon's stock closed up 0.7%.
