Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Transmission System (1TX + 1RX)

The Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Transmission System (1TX + 1RX) is a significant upgrade within Hollyland's wireless lineup. Positioned above the Pyro S and Pyro H, the Ultra model breaks past previous limitations by introducing true 4K60 transmission, a massive range boost, and ultra-low latency.

Here is a breakdown of what makes this system standout for professional film sets, live broadcast, and multi-user monitoring.

Key Upgrades & Specifications

Core Strengths

• True 4K60 Cinematic Quality: Unlike older models that max out at 4K30, the Ultra transmits 4K video at 60fps at a high 12 Mbps bitrate over HDMI. It also natively supports fractional frame rates (like 23.98 or 59.94 fps) demanded by professional broadcast and cinema workflows.

• TWiFi & DFS Technology: Instead of standard dual-band swapping, Hollyland’s TWiFi tech builds a composite link using both 2.4 GHz and 5 GHz signals simultaneously. Paired with Dynamic Frequency Selection (DFS) to unlock restricted wireless channels, it heavily cuts down on dropouts in signal-dense environments.

• Focus Mode (20ms Latency): When pull-focus accuracy is vital, triggering "Focus Mode" drops the latency to an incredibly tight 20ms (at 1080p30). For higher bandwidth feeds, latency sits around 40ms for 1080p60 and 45ms for 4K60.

• Infinite Scalability:

  • Standard Mode (Deactivated Broadcast): Supports up to 4 dedicated physical receivers and 2 mobile app connections simultaneously over the full 4,900-ft range.

  • Broadcast Mode (Activated): Allows unlimited Pyro receivers to pull the same video feed at a slightly condensed (but still massive) 2,300-ft range—ideal for massive crew operations.

• Smart Freeze-Frame Fail-Safe: If the wireless link takes an unexpected hit, the receiver instantly freezes the last clean frame (or pulls up a pre-loaded custom image) rather than cutting to a jarring black screen, preventing production panic.

Power & Build Physicals

The units utilize a rigid, heat-dissipating build weighing 320g each. They feature multiple powering workflows: standard DC barrel inputs (6–16V), integrated battery plates (NP-F/L-Series on the transmitter, and a highly requested V-mount plate on the receiver), alongside multi-use USB-C ports.

Bonus Workflow: The USB-C port on the receiver also supports plug-and-play UVC (USB Video Class). You can run a cable straight from the receiver into a computer, and it instantly behaves like a high-end webcam for direct streaming via Zoom, OBS, or YouTube without a capture card.
