Hollyland Pyro S 4K HDMI/SDI Wireless Video Receiver

The Hollyland Pyro S 4K HDMI/SDI Wireless Video Receiver (RX) is the dedicated receiving node for the Pyro S wireless transmission ecosystem.

Sold as an individual unit, this standalone receiver allows production crews to expand their existing Pyro S footprint. Because a single Pyro S transmitter can simultaneously broadcast to up to four hardware receivers, adding individual RX units allows you to deliver real-time, independent video feeds to a 1st AC (Focus Puller), the Director, the Client Village, and a Video Village switcher without adding latency or messy distribution amplifiers.

Core Signal & Hardware Capabilities

• Dual-Band Wireless Sync (2.4 GHz & 5.8 GHz): The receiver utilizes Hollyland's Auto Frequency Hopping (AFH) technology. It continuously downlinks data across both bands simultaneously. If local venue Wi-Fi or heavy production radio traffic interrupts one frequency, the receiver automatically prioritizes the clean band to guarantee a stable stream without tearing or black screens.

• Dual Monitoring Outputs (HDMI + 3G-SDI): Engineered to handle multiple workflows seamlessly. The receiver features a full-sized HDMI output supporting monitoring up to 4K at 30fps, alongside a robust 3G-SDI output optimized for production monitors, broadcast viewfinders, or standard studio switchers at up to 1080p60.

• UVC Live-Stream Integration: Features a built-in USB-C port supporting standard UVC (USB Video Class) protocol. By plugging a USB-C cable directly from the receiver into a computer, it serves as a plug-and-play webcam source. This allows you to capture the high-definition video transmission natively in OBS Studio, vMix, Zoom, or Teams without needing an external capture card.

• Smart Identification Accents: To prevent confusion when managing multiple wireless devices in a production kit, the receiver chassis features bright Blue corner tags and a blue 4K badge, distinguishing it instantly from the red-accented transmitter units.

Technical Specifications Matrix

Dual Performance Configurations

When paired with the transmitter, the receiver responds to two globally configured optimization modes via the system menu:

1. Smooth Mode: Prioritizes transmission speeds over raw detail, maintaining the strict 50ms latency limit. This setting is optimal for focus pullers or camera operators who require zero noticeable delay to track immediate movement.

2. HD Mode: Locks the processing bandwidth to its maximum bitrate (up to 12 Mbps), ensuring the cleanest compression algorithms and full color depth. This mode is ideal for director’s monitors, makeup stations, or client review stations where fine details matter most.

What is Included in the Box

• 1 × Pyro S 4K Wireless Video Receiver (Blue Accents)

• 3 × Paddle Antennas (2 for operational mount + 1 spare)

• 1 × 1/4"-20 Cold Shoe Mount Adapter

• 1 × Right-Angle DC Power Adapter Cable

On-Set Grouping Tip: When deploying multiple Pyro S receivers across a large set, you can easily pair a new RX unit by using the internal menu's auto-pairing function or grouping them via a single button press when placed next to the transmitter. If you encounter signal degradation on set, utilize the receiver's built-in OLED screen to run a local channel scan. It will visually graph the RF noise on the 2.4 GHz and 5.8 GHz spectrums, helping you manually lock onto the clearest local channel sequence.
