SDR Transmission Transmitter DJI

Podrobný popis

DJI SDR Transmission uses both Software-Defined Radio and Wi-Fi technology for wireless video transmission. SDR technology takes video transmission performance to a whole new level, offering increased stability, interference immunity and higher obstacle penetration. For situations that require temporary monitoring, DJI SDR Transmission also enables Wi-Fi transmission. Transmitter only.

• SDR ("Software-Defined Radio") transmission, stable and resistant to interference
• Extended transmission distance, up to 3 km, increased obstacle penetration
• High transmission speed, excellent image quality
• Video monitoring also over USB-C interface
• Broadcast mode, unlimited number of receivers
• DJI Ronin app support

Transmission over a distance of kilometres
DJI SDR Transmission has a range of up to 3 km, allowing you to capture truly dynamic footage. Combined with excellent signal penetration capabilities through obstacles, it meets the requirements for live transmission monitoring even in challenging locations.

20 Mbps, 1080p FHD quality
The DJI SDR Transmission supports live 1080p60 video transmission at bitrates up to 20 Mbps. It also supports seamless automatic frequency switching in the 2.4 GHz, 5.8 GHz and DFS bands. In the event of interference, it can automatically switch to the optimal channel to deal with cluttered environments. It also supports metadata transfer from common film cameras such as ARRI and RED via SDI. This gives directors, cinematographers and DIT teams quick access to detailed real-time shooting information.

Unlimited number of receivers
In Broadcast mode, each transmitter can be connected to an unlimited number of receivers, enabling high-quality monitoring for multiple users. A latency of only 35 ms ensures smooth monitoring and efficient collaboration.

Communication functions
DJI SDR Transmission enables one-to-one real-time communication between receiver and transmitter for seamless camera-to-camera conversations
and the director or client.

Compact, lightweight, portable
With foldable antennas and a lightweight design of approx. 145 g (for both the transmitter and receiver units) , it facilitates easy handling and allows for non-traditional mounting methods.

USB-C port
DJI SDR Transmission supports multiple monitoring methods and can simultaneously transmit three SDR signals and two Wi-Fi signals. The receiver can display video on monitors via an SDI/HDMI interface, and the transmitter also allows direct connection to smartphones or tablets via Wi-Fi for dual-channel monitoring without the need for a receiver. An innovation is the USB-C output monitoring: users can connect the receiver to a smartphone or tablet using a USB-C cable to ensure smooth and stable monitoring.

The DJI Ronin app
When the DJI SDR Transmission is connected to the DJI Ronin app in Broadcast mode, users can seamlessly switch between camera indices in the app. The app supports local recording and the recorded content can be further played back. The app offers auxiliary monitoring tools such as LUT correction, Peaking, Waveform and False Color, enabling professional monitoring.

The app also supports Force Mobile, Virtual Joystick, and DJI stabilizer re-adjustment. When DJI SDR Transmission is connected to the app in SDR Control or Wi-Fi mode, users can switch channels in the app while monitoring their quality. The app also supports PTP camera control, displays and adjusts aperture, shutter, ISO and even allows you to trigger shooting functions
and video recording via the app. In addition, it supports control of Sony's CEC cameras, which provides Mirror Control mode.

Power
Thanks to the integrated power supply, the transmitter can - when used with the DJI RS 4 Pro, DJI RS 4 or DJI RS 3 Pro - be mounted on the stabilizer and powered directly from it, eliminating the need for a separate battery. The transmitter and receiver also support standard NP-F or USB-C PD batteries (9 V / 2 A).
