Meet ATOM: a smart home security robot that auto-tracks intruders and lets you yell at them from your smartphone. It features face detection, 2-way audio, motion/audio detection, encryption, and day/night tracking. 10-second video alert is available under premium plans.
The camera tracks moving people and takes full 1080p video. It lets you define custom activity zones. You can find out more about it on Kickstarter.
