We present the new Dji Combo Transmitter that integrates both the transmitter and the receiver, what characterizes this brand is its good image and audio quality as well as an incredible transmission. The Dji Combo Transmitter is preferred for your audiovisual productions as well as for professional use.
Built on software defined radio technology, DJI SDR Transmission uses both SDR and Wi-Fi video transmission modes. SDR technology takes video transmission performance to the next level by offering improved stability, interference resistance and penetration. For situations requiring interim monitoring, DJI SDR Transmission also incorporates Wi-Fi transmission to offer more flexibility to film crews.

Mileage transmission and robust penetration
DJI SDR Transmission can reach up to 3 km, [1] allowing it to be used in large and dynamic recording scenarios. Combined with higher level penetration capabilities, it meets the requirements of live transmission monitoring in various complex situations.
High bit rate of 20 Mb/s and 1080p FHD image quality
DJI SDR Transmission allows live streaming in 1080p/60 fps, with a high bit rate of 20 Mb/s, [2] ensuring smooth monitoring and collaboration.
Automatic frequency hopping without interruptions
DJI SDR Transmission enables efficient frequency hopping in the 2.4 GHz, 5.8 GHz and DFS bands. In case of interference, it can automatically switch to the optimal channel, for easy troubleshooting in complex environments.
Unlimited number of receivers
In Broadcast mode, each transmitter can be connected to an unlimited number of receivers to provide a high quality monitoring experience for multiple collaborators and meet the independent monitoring needs of different professional roles.
Additional functions
Low latency transmission: 35 millisecondsThe minimum latency of only 35 ms [3] ensures smooth monitoring and efficient collaboration smooth monitoring and efficient collaboration.

Metadata transmission for professional use
DJI sDR Transmission enables transmission of metadata from leading film cameras such as ARRI and RED to SDI*, giving directors, digital imaging technicians and cinematographers quick access to detailed footage information in real time.
|
Communicate via voice callsDJI sDR Transmission enables real-time personal communication [4] between the receiver and the transmitter, allowing the cinematographer to have fluid conversations with the director or client at any time.

Communicate by voice calls
DJI SDR Transmission enables real-time personal communication [4] between the receiver and the transmitter, which makes it possible for the cinematographer to maintain fluid conversations with the director or client at any time.
Control of the RS Series stabilizers [6]
Compatible with Force Mobile, virtual joystick and stabilizer re-centering functions. |
Channel configuration
When DJI SDR Transmission is connected to the app in SDR Control mode or Wi-Fi mode, users can switch channels in the app and monitor channel quality simultaneously. |
Camera control*
DJI sDR Transmission supports PTP control over cameras, display and adjust aperture, shutter, ISO and even activate the functions of taking photos and recording videos from the camera through the app. In addition, it supports CEC control for Sony cameras, so you can use mirrored control mode.
