Why choose the DJI SDR Transmission TX?
- 1080p/60fps video transmission for sharp, fluid monitoring
- Up to 20 Mbps bitrate for clear and stable image quality
- Long-range transmission up to 3 km in SDR mode
- Low-latency performance for responsive real-time monitoring
- Broadcast mode support for connection with an unlimited number of receivers
- Wi-Fi monitoring on smartphones and tablets without requiring a receiver
- SDI and HDMI input support for flexible camera compatibility
- Lightweight, compact design with foldable antennas
- DJI Ronin app compatibility with advanced monitoring tools
High performance and versatile workflow
The DJI SDR Transmission Transmitter supports 1080p video at 60 fps with a maximum bitrate of up to 20 Mbps, giving you smooth and detailed image transmission. Thanks to Software-Defined Radio (SDR) technology, it provides stable, interference-resistant performance over long distances of up to 3 km, making it a great choice for demanding shoots in larger environments.
Unlimited receivers in Broadcast mode
In Broadcast mode, the DJI SDR Transmission TX can connect to an unlimited number of receivers (receiver not included in this set). This makes it an excellent solution for productions where multiple crew members need to monitor the same footage at the same time. It is a practical option for teams that value smooth collaboration and better communication on set.
Low latency and metadata transmission
The transmitter offers highly responsive monitoring with latency as low as 35 ms. It also supports metadata transmission via SDI from professional cinema cameras such as ARRI and RED, allowing quick access to valuable shot information during production.
Built-in voice communication
The DJI SDR Transmission TX supports simultaneous voice communication between the transmitter and receiver, helping crew members coordinate more effectively during filming. It is a useful feature for smoother teamwork and faster execution on set.
Flexible monitoring options
For even more convenience, the transmitter supports multiple monitoring methods, including direct connection to smartphones and tablets via Wi-Fi. This enables a more affordable dual-channel monitoring setup without the need for a separate receiver, giving you extra flexibility while filming.
Compact and lightweight design
Weighing only around 145 g, the DJI SDR Transmission Transmitter is easy to carry and simple to integrate into mobile production setups. Its foldable antennas make storage and transport easier, while multiple mounting options help it adapt to a wide range of shooting scenarios.
Compatible with the DJI Ronin app
When paired with the DJI Ronin app, the transmitter becomes even more powerful. The app gives you access to advanced monitoring tools such as LUT, peaking, waveform, and false color. It also supports local recording and playback, allowing you to quickly review footage. You can remotely control your camera and gimbal, switch channels, and monitor signal quality in real time for a more efficient shooting experience.
