The Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Transmitter adds reliable long-range wireless video transmission to professional production workflows. Designed for flexible on-set monitoring and video distribution, the transmitter features both HDMI and SDI input ports capable of delivering line-of-sight wireless transmission at distances up to 4900'.
Hollyland’s TWiFi transmission technology combines automatic frequency hopping with a composite signal link to maintain stable, high-clarity 4K60 video transmission while achieving low 20 ms latency for responsive real-time monitoring. Multiple operating modes provide added versatility for different production environments and workflow requirements.
The Pyro Ultra transmitter is also fully backward compatible with the entire Hollyland Pyro ecosystem, allowing seamless integration into existing wireless video setups and multicamera production workflows.
Unlimited Linking
The Pro Ultra ecosystem can be expanded to include unlimited receivers getting footage from a single transmitter unit, all while continuing to deliver stable wireless signals.
TWiFi Transmission Technology
TWiFi is Hollyland's new proprietary codec that creates a composite link out of 2.4 and 5 GHz wireless signals for secure communications. The system can then ensure line-of-sight transmission up to 4900'. On top of this, automatic frequency hopping avoids signal interference in crowded network environments. Dynamic Frequency Selection unlocks more of the wireless spectrum in regulated regions for additional flexibility.
Broadcast Mode
When enabled, Broadcast mode delivers real-time signal monitoring to a wide variety of receiver units from 2300' away. When deactivated, the standard setup supports up to six monitoring screens—four receivers and two mobile apps—up to 4900'.
Focus Mode
When trying to complete precise focus pulls, Focus mode maintains a low latency to ensure a responsive monitoring environment. Latency varies depending on the output resolution of your footage, measuring 20 ms at 1080p30, 40 ms at 1080p60, and 45 ms at 4K60.
Flexible Streaming
The Pyro Ultra features both UVC and RTMP streaming. Plug-and-play connectivity and flexible platform compatibility make the receiver ideal for live production and remote collaboration.
Freeze Frame
The system automatically freezes the last frame on screen when an unexpected cut occurs to give production crews time to recover. You can even set up a custom image as a default display to maintain visual consistency.
Multiple Power Options
The transmitter unit features a DC power input to connect a separately available power supply. An NP-F battery plate allows you to integrate an L-series battery for longer shoot times on set.
