DJI SDR Transmission Combo supports SDR technology and enables wireless video transmission at up to 1080p/60 quality over distances up to 1000 meters using DFS frequency selection and up to 200 meters on standard 2.4/5 GHz bands. Although DJI specifies up to 3000 meters via DFS, actual usable range depends on regional frequency regulations. Tests in Moscow confirm stable transmission up to 1000 meters; near sensitive government facilities, available frequencies may be limited to standard 2.4/5 GHz. The devices feature SDI and HDMI ports (inputs on transmitter, outputs on receiver), a 3.5 mm mini-jack, and two USB-C interfaces per unit. On the transmitter, one USB-C port is used for power or gimbal connection; on the receiver, one USB-C port functions as a video output. Minimum latency is 0.035 s in SDR mode, with a maximum of 0.11 s over Wi-Fi. When connected to a tablet or smartphone, the receiver can control DJI RS 4 Pro, RS 4, and RS 3 Pro gimbals as well as compatible camera functions (see compatibility list). Additional features include SDI metadata transmission for ARRI and RED cameras and support for 1080p/60 live streaming up to 20 Mbps. The transmitter can output to an unlimited number of receiving devices. Power options include NP-F970 battery slot and USB-C. Included: DJI SDR receiver and transmitter, USB-A to USB-C cable, TX mounting adapters for camera and gimbal. Video presentation in English available.
