Meet the Orbii: a smart robotic ball that you can roll around in your home to keep an eye on things. It has a HD camera, a microphone, and environmental monitoring sensors (temperature, humidity, air quality). The device captures high definition video with a 90-degree wide-angle lens. When it detects any unexpected motion, it starts recording.
Orbii relies on machine learning algorithms to learn about your environment to better serve you. You also get cloud storage and wireless charging. More information is available here.
