DJI SDR Technology – Stable, Interference-Resistant Video Transmission

At the heart of DJI SDR Transmission Combo is Software Defined Radio technology, which enables video signals to be transmitted through a dedicated wireless connection designed for professional monitoring.

Unlike conventional Wi-Fi-based video transmission solutions, the DJI SDR Transmission system is optimised for longer transmission distances, lower latency, and greater resistance to interference.

On professional film sets, radio signals may be affected by metal structures, walls, other wireless devices, and electromagnetic interference. DJI SDR technology helps maintain a stable connection between the transmitter and receiver in these environments.

The system supports automatic frequency hopping to adapt to changing radio-frequency conditions. Depending on regional regulations, it operates in the 2.4 GHz and 5 GHz frequency bands.

This makes DJI SDR Transmission Combo suitable for demanding filming situations where reliable video transmission is important for both the camera operator and the wider production team.

Up to 2 km Transmission Range Under European Regulations

DJI SDR Transmission Combo can wirelessly transmit video signals over distances of up to three kilometres under FCC-compliant conditions. Under European CE regulations, the maximum transmission range is 2 kilometres.

These figures were achieved in an open environment without significant obstacles or radio-frequency interference. Measurements were conducted in Control mode with Broadcast mode disabled.

Actual transmission range depends on filming conditions, device positioning, antenna placement, and surrounding interference sources.

Long-range transmission is particularly useful for outdoor filming, sports events, large studios, and productions where the camera needs to operate far from the director or monitoring team.

For example, a camera operator can film moving action across a large area while the director monitors the camera feed on a separate display.

Wireless connectivity reduces the need for long video cables and gives camera operators greater freedom of movement.

Full HD 1080p Video Transmission at up to 60 fps

DJI SDR Transmission Combo supports Full HD video signals at resolutions of up to 1920 × 1080 pixels and frame rates of 60 fps, providing smooth and detailed images for professional monitoring.

The system supports 1080p video at 23.98, 24, 25, 29.97, 30, 50, 59.94, and 60 fps. It also supports 720p video at 50, 59.94, and 60 fps, as well as 1080i signals subject to operating-mode restrictions.

The maximum transmission bitrate reaches 20 Mbps, helping preserve image quality and detail during wireless transmission.

The system uses H.264 video encoding, which provides a balance between image quality, bitrate, and transmission latency.

Full HD image quality makes it possible to monitor framing, lighting, focus, and camera movement.

It is important to note that DJI SDR Transmission Combo is primarily designed for video transmission and monitoring, rather than replacing the camera’s original high-resolution recordings. For example, when shooting in 4K, the system can display the camera’s video signal configured to a compatible Full HD output format.

Minimum 35 ms Latency for Real-Time Monitoring

In professional filmmaking, it is important that camera operators and other crew members see the camera feed with as little delay as possible.

DJI SDR Transmission Combo offers a minimum 35-millisecond transmission latency, excluding delays introduced by the camera and monitor themselves.

According to DJI measurements, the total end-to-end video delay is approximately 80 milliseconds when camera and monitor latency are included. These measurements were made using a 1080p/60fps video signal with Broadcast mode disabled.

Low latency is particularly useful when filming moving subjects, monitoring complex camera movements, and shooting scenes where the director needs to assess framing quickly.

It also helps focus pullers monitor the camera feed with minimal delay.

Thanks to its fast video transmission, DJI SDR Transmission Combo is suitable for professional productions where precise timing and real-time collaboration are essential.

Transmitter and Receiver Included

DJI SDR Transmission Combo includes a DJI SDR Transmission transmitter and receiver, which together form a complete wireless video transmission system.

The transmitter connects to a camera through HDMI or SDI and sends the video signal wirelessly to the receiver.

The receiver captures the signal and outputs it to an external monitor or another compatible display device.

This setup allows the camera and monitoring equipment to be positioned separately without requiring a long video cable between them.

In addition to the transmitter and receiver, the package includes the antennas and mounting accessories specified by the manufacturer. Exact package contents depend on the product configuration and should be checked for the specific retail package.

The transmitter and receiver form a flexible system that can be expanded with additional compatible receivers when necessary.

According to DJI, the maximum Wi-Fi transmission range reaches 200 metres under suitable conditions.

This feature is particularly useful when a quick, compact monitoring solution is required and the maximum range of a professional SDR connection is unnecessary.

When using Wi-Fi, it is important to consider that its operating range and resistance to interference differ from those of the dedicated SDR connection.

Users can therefore choose the most suitable operating mode based on filming conditions and available equipment.

Broadcast Mode for Multiple Receivers

DJI SDR Transmission Combo supports Broadcast mode, allowing one transmitter to send the video feed to multiple receivers simultaneously.

According to DJI, the system does not impose a fixed numerical limit on the number of receivers connected to a single transmitter in Broadcast mode.

This is a major advantage for larger productions where the director, camera assistant, production manager, and other crew members need to monitor the same camera feed.

For example, one receiver can be positioned at the director’s monitor, another at the focus puller’s workstation, and a third in the client monitoring area.

Broadcast mode helps create a flexible monitoring system in which several people can follow the same camera feed simultaneously.

However, maximum transmission range and other operating parameters may differ in Broadcast mode compared with Control mode.

Certain remote control and communication features are available only in Control mode.
