There are also two dedicated buttons for moving forward and backward. A single finger drag controls the camera's pitch and the drone's yaw, and a two-finger drag controls the altitude and horizontal direction. The Hover Camera doesn't come with a controller it's all done with your fingers and a couple of virtual buttons in the mobile app, as long as you're connected to the drone's WiFi hotspot. Wang said you can expect the Hover Camera to achieve similar level of image quality as modern high-end smartphones. There's also a downward-facing 3-megapixel camera and a sonar underneath to help stabilise the drone itself. Since it's only on a single-axis gimble, it uses electronic image stabilisation which is still being fine-tuned. The main camera at the front takes 13-megapixel stills as well as 4K video, and it comes with a dual-tone flash which might come in handy. We use a completely proprietary algorithm, as we're squeezing every single drop of juice out of the Snapdragon 801 and we don't use open source code because it's not good enough." Something of this size needs to be built from ground up. "It's a lot harder to build things of this size versus bigger things. For these reasons alone, MQ Wang, CEO of Zero Zero Robotics and a PhD graduate at Stanford University, isn't worried about his product being copied.
