Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Transmitter

Overview

The Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Transmitter is a professional wireless video transmitter designed to send UHD 4K60 signals over long distances with low latency for on-set monitoring, live production, and multi-user workflows. Equipped with HDMI 2.0 and 3G-SDI inputs, it integrates easily into professional camera and video systems while supporting broad compatibility across the Hollyland Pyro ecosystem.

Built for demanding production environments, the Pyro Ultra transmitter combines Hollyland's TWiFi transmission technology, flexible monitoring modes, and streaming support in a compact form factor. With automatic frequency hopping, backward compatibility with the wider Pyro family, and support for unlimited receiver expansion, it is well suited to complex wireless video workflows.

Core Features

• This professional wireless video transmitter supports UHD 4K60 transmission for high-quality production monitoring.
• Its HDMI 2.0 input, HDMI 2.0 loop output, and 3G-SDI input provide flexible integration with a wide range of professional video equipment.
• TWiFi transmission technology combines 2.4 and 5 GHz wireless signals with automatic frequency hopping for stable, interference-resistant performance.
• The transmitter supports line-of-sight transmission up to 1500 m for long-distance wireless video workflows.
• Broadcast mode, Focus mode, UVC support, and RTMP streaming expand its usefulness across monitoring and live production applications.
• Backward compatibility with the Hollyland Pyro family allows easier integration into existing wireless video setups.

Long-Range Wireless Performance

The Pyro Ultra transmitter is built for extended-range wireless video transmission, supporting line-of-sight distances up to 1500 m. Hollyland's TWiFi technology creates a composite wireless link using both 2.4 and 5 GHz frequencies, while automatic frequency hopping helps minimise interference and maintain stable image transmission in crowded operating environments.

Broadcast and Focus Monitoring Modes

Broadcast mode is designed for productions that need reliable real-time monitoring across multiple receivers, making it suitable for larger crews and more complex workflows. Focus mode prioritises low latency to create a more responsive monitoring environment for precision focus pulling, with latency as low as 20 ms depending on the selected output resolution.

Streaming and Workflow Flexibility

With support for both UVC and RTMP streaming, the Pyro Ultra transmitter can adapt to live streaming, remote collaboration, and plug-and-play production workflows. The wider ecosystem can be expanded to support unlimited compatible receivers from a single transmitter, helping crews scale monitoring setups as production requirements grow.

Reliable On-Set Operation

When unexpected signal interruption occurs, the system can freeze the last frame on screen to help maintain continuity while the crew restores the feed. Users can also configure a custom default image to preserve visual consistency during interruptions, adding another layer of professionalism to live and on-set workflows.

Professional Connectivity and Compatibility

HDMI 2.0 and 3G-SDI connections provide compatibility with a wide variety of professional cameras and video devices, while the USB-C port adds additional workflow flexibility. Backward compatibility with the broader Hollyland Pyro family makes the transmitter a convenient choice for expanding pre-existing wireless systems.
