Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Dual Receiver Transmission System

Overview

The Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Dual Receiver Transmission System is a professional wireless video kit designed to deliver long-range UHD 4K60 transmission with low latency for on-set monitoring, live production, and multi-user workflows. Including one transmitter and two receivers, it supports HDMI and 3G-SDI connectivity for broad compatibility across cameras, monitors, switchers, and other professional video equipment.

Designed for demanding production environments, the Pyro Ultra combines Hollyland's TWiFi transmission technology, flexible monitoring modes, streaming support, and adaptive output resolution in one versatile system. It is also backward compatible with the wider Pyro family, making it a practical choice for expanding or upgrading an existing wireless video setup.

Core Features

• This wireless transmitter and dual-receiver set supports UHD 4K60 video transmission for high-quality production monitoring.
• Its HDMI and 3G-SDI inputs and outputs provide flexible integration with a wide range of professional video devices.
• TWiFi transmission technology combines 2.4 and 5 GHz wireless signals with automatic frequency hopping for stable, interference-resistant performance.
• The system supports line-of-sight transmission up to 1500 m for long-distance 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 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 Multi-Device Flexibility

With support for both UVC and RTMP streaming, the Pyro Ultra can adapt to live streaming, remote collaboration, and plug-and-play production workflows. In standard operation, the system supports up to six monitoring screens, including four receivers and two mobile apps, while the wider ecosystem can be expanded to support unlimited compatible receivers from a single transmitter.

Reliable On-Set Workflow Features

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, while adaptive output resolution allows the receiver to automatically match connected downstream devices for easier setup across varied production systems.

Professional Connectivity and System Compatibility

HDMI 2.0 and 3G-SDI connections on the transmitter and receivers provide compatibility with a wide variety of professional camera and monitoring equipment. The inclusion of USB-C support further extends workflow options, and backward compatibility with the broader Pyro family makes the system a convenient addition to pre-existing Hollyland setups.
