DJI is a brand known for manufacturing some of the best drones in the industry. Their drones tend to introduce new features model by model over the years and with different series such as the Phantom, Air, and Mavic which contain different specs respective to their purpose. 

Released back in 2016, the DJI quad Phantom 4 pro was released after the Phantom 4 in the same year. The Phantom 4 pro packs a larger 1 inch CMOS sensor as opposed to the standard 1/2.3-inch class ones used by other drones at the time. Along with that, the Phantom 4 was also equipped with mechanical shutter and aperture control. The drone is also equipped with the OcuSync video transmission technology that allows the device's range to stretch further. The Phantom 4 records video from approximately 4.3 miles if the conditions are optimal. Other handy features in the drone include point of interest mode, Waypoints, Follow me mode, Terrain follow, Tripod mode and Active track abilities. The drone also contains the new omnidirectional sense and avoid system to continuously scan its environment in order to avoid obstacles. As opposed to its predecessor, the Phantom 4 pro packs a "return to home'' where it retraces its steps to return to point of origin.
