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

Add up to 4K60 wireless video transmission to your production using the versatile Pyro Ultra 4K HDMI/SDI Wireless Video Dual Receiver Transmission System from Hollyland. The system includes a wireless transmitter, two wireless receivers, different-sized antennas, a USB-C adapter, a D-Tap to DC cable, a DC power adapter, and a dual ball head to cold shoe mount adapter. HDMI and SDI ports accept line-of-sight transmission from up to 4900′ away. TWiFi transmission technology creates a composite link with automatic frequency hopping for exceptional clarity and a low 20 ms latency. Additional operating modes make for increased capabilities, depending on the needs of your production. The Pyro Ultra is backwards compatible with the entire Pyro family to work seamlessly with your preexisting workflows.

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 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.

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′.

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.

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.

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.

The receiver automatically adapts its HDMI or SDI output resolutions to match downstream devices, ensuring compatibility across setups.
