DJI Releases SDR Transmission II System for 4K 60fps HDR Video Transmission up to 2.5 Miles
Key points
- SDR Transmission II sends 4K 60fps HDR video at 50Mbps.
- Transmission range is up to 2.5 miles (4 km).
- Supports up to five transmitters and 40 receivers simultaneously.
- Latency is as low as 35 milliseconds.
Enhanced Video Transmission Capabilities
DJI has introduced the SDR Transmission II system, an upgrade to its professional video transmission technology. The new system is capable of transmitting 4K 60 frames per second (fps) High Dynamic Range (HDR) video at a bitrate of 50Mbps. This represents a significant improvement over the original SDR Transmission system, which was limited to 1080p video at 20Mbps.
Extended Range and Multi-Camera Support
The SDR Transmission II system extends the transmission range to 2.5 miles (4 km), an increase from the previous 1.8 miles (3 km). This extended range allows for reliable video links in various challenging environments, including open stadiums, dense forests, and demanding car-to-car or FPV drone shots. The system supports complex multi-camera setups, allowing up to five transmitters and 40 receivers to operate simultaneously.
Remote Control and Low Latency
Beyond video transmission, the system enables remote control functionalities. A single transceiver can connect to up to eight others, facilitating remote adjustment of camera settings and control by camera operators and focus pullers. The system boasts a low latency of 35 milliseconds, which is critical for responsive commands such as focus pulling and gimbal movement. It also includes features like tap-to-switch between camera feeds without rebooting, smartphone monitoring, and assist tools such as LUTs, focus peaking, and waveforms. PTP control is supported for compatible cameras to adjust functions like capture, aperture, shutter speed, and ISO.
Availability and Pricing
The DJI SDR Transmission 2 transceivers are available starting at €349 or £309, with a Combo two-pack priced at €629 (£559). US availability is not yet confirmed, potentially due to existing restrictions on certain DJI products.
