The DJI SDR Transmission Combo is a professional digital video transmission system engineered to deliver ultra-stable signal, low latency, and exceptional image quality for cinematic production and multi-camera workflows. Built on DJI’s O3 Pro SDR (Short-Distance Range) technology, it enables 1080p video transmission at up to 60 fps with minimal latency of only 30 ms, ensuring real-time responsiveness between camera and monitor. Both the transmitter and receiver are constructed from high-strength aluminum alloy for enhanced heat dissipation and provide signal stability up to 2 km line-of-sight — ideal for complex film sets or open environments. The transmission module supports both SDI and HDMI protocols, offering seamless integration with professional cinema cameras like the DJI Ronin 4D, Inspire 3, and third-party systems. It supports real-time streaming to up to four receivers simultaneously, allowing directors, focus pullers, and production teams to collaborate in sync. The camera and lens control functions can be managed wirelessly via the built-in interface or through the DJI Transmission app, enabling remote adjustment of focus, iris, and zoom (FIZ). Its Broadcast Mode prioritizes video stability, while Control Mode balances transmission and command response. Compact, durable, and fully integrated into the DJI PRO ecosystem, the DJI SDR Transmission Combo is the perfect choice for film production, professional live streaming, and dynamic set environments, where reliability and cinematic performance are essential.
