A professional 4K wireless video transmission system with low latency and flexible TX/RX deployment
The DJI SDR Transmission 2 Combo is a professional wireless video transmission solution designed for productions that need to send a high-quality camera feed to multiple monitors or receivers, with support for 1 TX to 8 RX with control and multi-group operation with up to 5 transmitters and 40 receivers.
The system supports DCI 4K/60fps, 10-bit HDR, and H.265 video at bitrates up to 50 Mbps, with transmission range up to 4 km and latency as low as 35 ms, giving production teams near-instant monitoring and more responsive control for professional shoots.
Overview
DJI SDR Transmission 2 is designed as an evolved wireless video system that combines high image quality, long-range transmission, low latency, and flexible deployment for complex on-set environments.
The system uses a transceiver design, allowing each unit to switch between TX and RX modes. This means the same unit can work as a transmitter or receiver depending on the needs of the shoot, without requiring users to define the TX-to-RX ratio in advance.
With Auto Channel 2.0, transceivers can recognize one another and intelligently coordinate frequencies, using more accurate spectrum scanning and conflict diagnostics to help maintain a stable connection even when multiple systems are operating side by side.
Key Features
1 TX to 8 RX with Control
One transmitter can feed up to eight receivers, with remote control support according to the provided information.
Multi-Group Transmission
Supports simultaneous operation of up to five transmitters and 40 receivers for complex production setups.
Auto Channel 2.0
Smart frequency coordination and seamless frequency hopping help maintain a stable feed when interference occurs.
DCI 4K/60fps
Supports DCI 4K video transmission up to 60fps with 10-bit HDR and H.265 encoding.
Up to 50 Mbps Bitrate
Encoding bitrate up to 50 Mbps helps preserve high-quality monitoring detail.
Up to 4 km Range
Transmission range reaches up to 4 km according to the provided text, suitable for wide and dynamic sets.
Low Latency Down to 35 ms
Low latency makes focus pulls, gimbal movement, and remote commands more responsive.
TX/RX Switchable
Each transceiver can switch between transmitter and receiver roles depending on the production setup.
Flexible Monitoring Outputs
Supports USB-C, HDMI, DP, and SDI according to the provided information for professional monitoring flexibility.
1 TX to 8 RX with Control and Multi-Group Operation
The system allows a single transmitter to feed up to 8 receivers, with remote control available for each receiver, making it suitable for the director, focus puller, camera operator, lighting team, client monitor, and production crew on set.
It can also operate with up to 5 transmitters and 40 receivers at the same time, helping production teams manage multiple cameras or groups within one location without sacrificing 4K image quality.
This makes it useful for cinema production, commercials, live events, studios, car shoots, crane setups, and sets that require organized multi-monitor viewing.
Auto Channel 2.0 for a More Stable Feed
When Auto Mode is enabled, the units recognize one another and coordinate frequencies intelligently, helping reduce conflicts and improve stability in locations where multiple wireless systems are operating.
The system supports more accurate spectrum scanning and conflict diagnostics, with seamless frequency hopping as conditions change, helping maintain a stable connection despite interference.
This is especially useful on large sets, live events, busy studios, or any production environment where multiple wireless video systems are running side by side.
SDR, Evolved — 4K Quality with Low Latency
DJI SDR Transmission 2 transmits DCI 4K/60fps video with 10-bit HDR support and H.265 encoding at bitrates up to 50 Mbps, providing high-definition monitoring during production.
The transmission range reaches up to 4 km according to the provided information, making it suitable for stadiums, wide production locations, car shoots, and dynamic scenes that require long-distance monitoring.
With latency as low as 35 ms, the video feed feels close to real time, which is important for tasks such as focus pulling, gimbal control, and accurately following motion.
TX/RX Switchable Transceiver Design
DJI SDR Transmission 2 uses a transceiver design, allowing each unit to be switched between TX and RX modes depending on the production requirement.
This gives crews more flexibility on set, since they do not need to define the number of transmitters and receivers in advance. Each unit can adapt to the shooting layout as needed.
The unit weighs approximately 136 g including antennas, helping reduce load on handheld gimbals and lightweight camera setups while remaining easy to mount across different rigs.
Pro Monitoring with Flexible Output
Camera feeds can be switched quickly directly from the transceiver or through the DJI Ronin app, making it easier to manage multiple cameras or video sources on set.
The ultra-high-definition, low-latency video feed can be output to professional monitors via SDI, HDMI, or DP ports depending on the workflow and setup used.
A smartphone or tablet can also be connected to the receiver via USB-C for a stable, high-bitrate wired monitoring feed.
DJI Ronin Ecosystem and Beyond
When paired with DJI RS series gimbals, the system allows wireless gimbal movement control and recording trigger through a smartphone, giving operators a more flexible shooting workflow.
It can also connect with DJI Ronin 2 and DJI Master Wheels for precise control of heavy cinema cameras mounted on car rigs or crane systems.
The system also supports connection with Osmo Action or Pocket series devices according to the provided information, enabling lightweight setups for sports and unconventional camera angles.
Multiple Power Options
The system supports power via NP-F battery, USB-C PD, or gimbal power according to the provided information, giving users flexibility in choosing the most suitable power method.
These options make it suitable for mobile shooting, gimbal work, cinema camera rigs, and longer production days where stable power is important.
