DJI Phantom 4 Pro RC Quadcopter
An uprated camera is equipped with a 1-inch Megapixel sensor capable of shooting 4K/60Fps video and burst mode stills at 14 fps. The adoption of Titanium alloy and magnesium alloy construction increases the rigidity of the Airframe and reduces weight, making the Phantom 4 Pro similar in weight to the Phantom 4. The Flight Autonomy system adds dual rear vision sensors and infrared sensing systems for a total of five-directions of obstacle sensing and four-directions of obstacle avoidance.

The Phantom 4 Pro controller integrates an upgraded Lightbridge HD video transmission system that adds 5.8 GHz transmission support. The ability to choose between 2.4GHz and 5.8GHz allows pilots to cut through interference and eliminates image lag caused when flying in an area with extensive 2.4GHz frequency use. Normally, Wi-Fi video transmission systems use a 2.4GHz frequency to work with a controller using a 5.8GHz frequency as this prevents interference that can occur when both use the same frequency. If using the same frequency the video transmission system and the remote controller will interfere with each other, causing image lag. The use of two different frequencies has drawbacks in terms of flight performance. For example, flight performance will be affected when either of the two frequencies suffer interference.

The Lightbridge HD video transmission system used in the Phantom 4 Pro uses TDM (Time Division Multiplexing) to transmit signals, allowing it to send controller signals and receive video transmission signals at the same frequency. As the 2.4GHz frequency band is often affected by Wi-Fi, 4G cell towers, and other types of interference in urban areas, a 5.8GHz band will increase transmission reliability. When switched on, the Phantom 4 Pro evaluates local signal levels, automatically choosing the transmission frequency with the lowest level of interference. This ensures the optimum range of a maximum video transmission of 4.3mi (7km).
