Drone Cam is a "flying indoor security camera": it leaves a docking station, flies from room to room and alerts the owner when something is wrong. It works with Ring's other devices, so if an alarm goes off at the back door it is supposed to fly there and check. It records in 2K, has LED lights for night recording and can be scheduled for regular patrols, for example when the house is empty.
Rover Cam patrols preset routes at set times inside a business and streams continuous 4K video to the app. It can be set to start recording when it detects a person, has a periscope camera that rises above obstacles and two-way audio for talking to whoever is there. Both devices run on Ring's AI system, AI Pilot, and map the space themselves as they patrol.
According to TechCrunch, Amazon's previous attempt in this area, the Astro robot, was repurposed for business security and halted a few months later. Ring has faced privacy criticism in the past and says video from both devices is protected by its TAKE encryption. It is not known whether video can be stored locally rather than in the cloud.
