DJI SDR Transmission Receiver

The DJI SDR Transmission Receiver is designed for stable, high-quality video transmission on small-to-medium-sized shooting sets. It uses DJI’s proprietary technology to transmit footage up to 1080p60 resolution over long ranges. The SDR transmission system utilises a tri-bandwidth (DFS, 2.4 GHz, and 5.8 GHz) automatic frequency-hopping system, allowing for high penetration and distances up to 3 kilometres. This makes it ideal for transmitting footage from a camera rig to an unlimited number of receivers or mobile devices, particularly in crowded sets or areas with dense architecture where traditional consumer Wi-Fi-based solutions may struggle.

Robust Transmission up to 3,048 Metres

The DJI SDR Transmission receiver can receive wireless video from up to 3,048 metres 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.

High-Quality Image Transmission

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 colour.

Seamless Auto-Frequency Hopping

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.

Unlimited Number of Receivers

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.

Metadata Transmission

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.

Voice Call

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.

Camera/Gimbal Control

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.

Versatile USB-C Port

The transmitter supports multiple monitoring methods and can output three SDR and two Wi-Fi signals simultaneously. The receiver can output to monitors via SDI/HDMI, and the transmitter also allows for direct connection to smartphones or tablets over Wi-Fi for added compatibility. The receiver can also utilise a USB-C output with a USB-C cable to directly connect the receiver to a smartphone or tablet for smooth and stable monitoring.

Camera Source Switching

When the receiver is connected to the DJI Ronin app in Broadcast mode, users can seamlessly switch between camera sources within the app to quickly monitor different cameras.

App Monitoring Tools

The app supports local recording and playback, and recorded content can be reviewed on the playback page. It also supports mainstream monitoring assistance tools such as LUTs, peaking, waveform, and false colour, delivering a professional monitoring experience.

Power Options

The receiver can be powered directly via a USB-C cable using a USB PD fast charger, a standard USB power supply, or via an L-series battery using its built-in port on the back.
When used with the DJI RS 4 Pro, RS 4, or RS 3 Pro, the transmitter or receiver can be mounted on the gimbal and powered directly by it, eliminating the need for a separate battery.
