There are plenty of cool 4K drones on the market. Not all of them can be turned into a wearable action cam or security camera for your home. The PITTA drone is different. It is a modular selfie quadcopter with drone, camera, and action cam modules. You can put it on its charging cradle to use it as a security camera in your home.
The PITTA has orbit, auto-follow, panorama mode, auto-landing, return home, and other convenient features. The mobile app lets you control the drone and its various modes. You will be able to catch this drone at CES 2018.[Source]
