DJI has introduced a new video transmission device that will allow creators to control cameras and gimbals and view video from up to 1.8 miles away. Called DJI SDR Transmission (SDR stands for "software defined radio"), it's designed for use in "complex environments" and is targeting small- to medium-sized film crews.
The system consists of transmitter and receiver (each weighing 5.1 ounces), sold separately or in a combo. You can also purchase a phone or tablet holder kit, along with an RX to phone connection cable.
