DJI Phantom 4 Sense & Avoid Obstacle Avoidance
We all use our eyes to see and interact with the world. A forward Obstacle Sensing System gives the Phantom 4 it its own pair of eyes, empowering it to see in three dimensions and to react. In Normal Mode if it sees an obstacle coming close it will stop and hover. In TapFly, ActiveTrack and Smart Return Home modes it will avoid the obstacle, or hover to avoid a collision. It also gives you warnings so you always know what is happening to the Phantom. The downward facing Vision Positioning module contains dual cameras and dual ultrasonic sensors to offer five times more positioning accuracy than previous systems. Used indoors, it provides a GPS-like flying experience, giving you the confidence you need to fly indoors.
