Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Receiver

The Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Receiver expands your existing Pyro Ultra system with an additional monitoring station, supporting true 4K60 video at up to 1.5 kilometres line-of-sight from the transmitter. Featuring both HDMI and SDI outputs, this receiver integrates seamlessly into multi-monitor workflows for directors, cinematographers, DITs, and clients. Built-in UVC and RTMP streaming enable direct connectivity with live production platforms, while Focus Mode reduces latency to just 20 milliseconds at 1080p30 for responsive real-time monitoring during critical focus pulls and fast-paced camera work.

Unlimited System Expansion

The Pyro Ultra ecosystem supports unlimited receivers from a single transmitter, allowing productions to scale monitoring setups without signal degradation. Add this receiver to existing Pyro Ultra systems for additional on-set monitoring positions, client viewing stations, or remote workstations. Broadcast Mode supports unlimited receivers at ranges up to 700 metres, while standard operation accommodates up to six monitoring screens (four receivers plus two mobile apps) at the full 1.5-kilometre range.

TWiFi Transmission Technology

Hollyland's proprietary TWiFi codec creates a composite link using both 2.4 GHz and 5 GHz frequencies, ensuring stable reception even in congested RF environments. Automatic frequency hopping avoids interference from Wi-Fi networks, Bluetooth devices, and other wireless systems commonly found on location and in studios. Dynamic Frequency Selection (DFS) certification unlocks additional spectrum in regulated regions, providing more channels for reliable operation when working alongside broadcast equipment.

Focus Mode for Precision Work

When pulling focus or tracking fast-moving subjects, Focus Mode reduces latency to 20 milliseconds at 1080p30, 40 milliseconds at 1080p60, and 45 milliseconds at 4K60. This responsiveness ensures accurate focus adjustments without the lag that can compromise critical shots. The mode can be enabled across all receivers in a group, making it valuable for focus pullers, gimbals operators, and anyone requiring immediate visual feedback.

Flexible Streaming Integration

Both UVC and RTMP streaming are built into the receiver, enabling plug-and-play connectivity with streaming platforms, video conferencing software, and live production systems. UVC mode supports resolutions up to 4K60, while RTMP streaming delivers 1080p60 output. This dual-streaming capability makes the receiver suitable for live events, remote collaboration, and hybrid production workflows where wireless monitoring and streaming need to coexist.

Freeze Frame Protection

When signal interruption occurs, the receiver automatically freezes the last frame on screen rather than displaying a black or distorted image. This gives production teams time to troubleshoot and recover without losing visual reference. A custom 1920x1080 JPG image (under 1 MB, named "logo.jpg") can be uploaded as a default display, maintaining visual consistency and professionalism during temporary signal loss.

Adaptive Output Resolution

The receiver automatically adjusts HDMI and SDI output resolutions to match downstream devices, eliminating manual configuration when connecting to monitors, recorders, or switchers with different input requirements. This compatibility extends across the following formats:

• 720p at 50/59.94/60 fps
• 1080i at 50/59.94/60 fps
• 1080p at 23.98/24/25/29.97/30/50/59.94/60 fps
• 4K (3840x2160) at 23.98/24/25/29.97/30/50/59.94/60 fps

Pyro Ecosystem Compatibility

The Pyro Ultra receiver integrates seamlessly with existing Pyro Ultra transmitters and is backward compatible with Pyro 5, Pyro 7, Pyro H, and Vcore transmitters. This cross-compatibility allows productions to mix and match equipment across the ecosystem, scaling monitoring setups without replacing existing gear. Pyro 5 and Pyro 7 support both broadcast and non-broadcast modes, while Pyro H and Vcore operate in non-broadcast mode.

Package Includes

• Wireless receiver with HDMI and SDI outputs
• Easy-install short antenna (SMA male connector)
• USB-C cable for power and streaming

Power and Mounting

The receiver accepts 6.8-8.4V battery power input or 6-16V DC power input, providing flexibility for Sony NP-F batteries, V-mount/Gold mount systems, or mains power. Power consumption is 7W during operation. Weighing just 320 grams, the unit mounts easily on monitors, director's carts, or workstations using standard cold shoe or 1/4-inch thread mounting options.
