DJI SDR Transmission Combo

The DJI SDR Transmission Combo is a wireless HD video transmission system for professional cameras and the DJI RS 4 Pro, RS 4, and RS 3 Pro gimbals. It accepts camera feeds through HDMI or SDI connections for camera-to-monitor links. Under FCC conditions, its rated transmission distance reaches 3 km. Video is carried at resolutions up to 1920×1080 and frame rates up to 60 fps. Its SDR and Wi-Fi architecture is intended for live monitoring across professional cinematography and video production rigs.

The transmitter weighs 145 g, a relevant consideration when balancing a camera and accessories on a gimbal. Its body measures 86.5 × 32 × 64 mm, which helps determine clearance within a configured rig. A built-in battery is rated at 8.4 V, while the unit also accepts a 6.8–17.2 V input. The specified operating temperature range is −10 to 40 °C for use across varied production environments. One feed can be monitored by multiple receivers, supporting crews that need more than one viewing point.
