DJI SDR Transmission Receiver

For stable, high-quality video transmission on a small-to-medium-sized shooting set, the SDR Transmission Receiver from DJI is designed for long-range transmission of footage up to 1080p60 resolution using DJI's proprietary technology. SDR (Software Defined Radio) transmission uses a tri-bandwidth (DFS, 2.4 GHz, and 5.8 GHz) automatic frequency-hopping system, resulting in high penetration and distances up to 1.9 miles. The system is ideal for transmitting footage from a camera rig to an unlimited number of receivers or mobile devices, especially on crowded sets or around dense architecture that would otherwise overwhelm a conventional consumer Wi-Fi-based solution.

The DJI SDR Transmission receiver can receive wireless video from up to 10,000' from a transmitter using its proprietary SDR technology, which accommodates wide, dynamic filming areas. It has a minimal latency of just 35 ms, ensuring smooth monitoring and extended reach.

The system supports video transmission with up to 1080p60 resolution with a high bit rate of up to 20 Mb/s, ensuring smooth monitoring and collaboration with high image detail, crisp audio, and vivid color.

SDR technology supports seamless auto-frequency hopping across the 2.4 GHz, 5.8 GHz, and DFS frequency bands. In case of interference, it can automatically switch to the cleanest channel when operating in complex environments with many obstacles.

 

When the SDR Transmission system is connected to the app in SDR Control mode or Wi-Fi mode, users can also manually switch channels within the app and monitor channel quality simultaneously.

In Broadcast mode, each transmitter can connect to an unlimited number of receivers, providing a high-quality monitoring experience for multiple collaborators and meeting the independent monitoring needs of various professional roles.

SDR Transmission supports metadata transmission from mainstream cinema cameras like ARRI and RED via the SDI input. This provides directors, cinematographers, and DIT teams with quick access to detailed camera information in real time.

The Voice Call feature enables one-on-one real-time voice communication between the receiver and transmitter, allowing for seamless conversations between the cinematographer and the director or client at any time.

 

A compatible headset plugs into the 3.5mm jack on the unit, and when in Control mode, real-time voice communication is enabled. See DJI's Headset Compatibility List for compatible headsets.

The SDR Transmission system supports PTP control over cameras, displaying and adjusting aperture, shutter, ISO, and even triggering the camera's photo-taking and video-recording functions through the app. It also supports CEC control for Sony cameras using Mirror Control mode. See the DJI SDR Transmission Camera Compatibility list for compatible cameras.

 

When connected to a gimbal, it also supports Force Mobile, virtual joystick, and gimbal recentering functions when connected to the gimbal via the app.
