The Hollyland Pyro H 4K HDMI Wireless Video Transmission System (1TX + 1RX) is a complete, dual-band wireless monitoring kit tailored for independent filmmakers, content creators, live-streamers, and commercial video crews.
Building heavily upon the foundation of Hollyland’s legacy Mars series, this 1 Transmitter + 1 Receiver kit upgrades to a modern 2.4 GHz and 5 GHz dual-band wireless carrier. By abandoning fragile single-frequency streaming, the Pyro H provides an incredibly reliable, long-range connection that can survive heavy RF interference on modern film sets and corporate venues.
Core Hardware & Wireless Features
-
Auto Dual-Band Hopping (2.4 GHz & 5 GHz): Powered by Auto Frequency Hopping (ADH) technology, the Pyro H transmits video data across both frequency bands simultaneously. If the local environment is crowded with venue Wi-Fi or smartphone hot spots, the system instantly switches to the cleanest available channel block to eliminate frame dropping or black screens.
-
Streamlined HDMI-Only Layout: Built specifically for mirrorless camera platforms, handheld gimbals, and standard HDMI field monitors. By removing complex, heavy SDI BNC connectors, the system reduces the physical weight on your camera cage while natively passing through crisp video signals up to 4K at 30fps.
-
Transmitter (TX): 1× HDMI Input, 1× HDMI Loop-Out.
-
Receiver (RX): 1× HDMI Output.
-
-
1-to-4 Broadcast Multiplexing: While this standard kit comes configured as a 1TX + 1RX package, the backend transmitter is engineered to scale. A single Pyro H transmitter can broadcast video to four dedicated hardware receivers simultaneously. Alternatively, it can split the feed to 2 hardware receivers while casting via Wi-Fi to 2 mobile devices using the HollyView app.
-
Driverless UVC Live Streaming: The receiver features an integrated high-speed USB-C port supporting standard UVC (USB Video Class). By running a single USB-C cable straight from the receiver into a computer, it acts as a plug-and-play webcam source—letting you pump high-definition video directly into OBS Studio, vMix, Zoom, or YouTube Live without needing a separate capture card.

Dual Optimization Modes
Accessible via the interactive OLED side displays, the crew can change the system's processing priority on the fly depending on what the shoot demands:
-
Smooth Mode: The hardware dynamically manages the video bitrate to keep latency to its absolute lowest point (60ms). This configuration is crucial for roving Focus Pullers / 1st ACs who depend on real-time visual responsiveness to hit critical marks.
-
HD Mode: Locks the wireless stream to its maximum 12 Mbps threshold. This ensures the cleanest compression algorithms and full color depth, making it ideal for the Director's Monitor, client viewing booths, or makeup stations where high fidelity is preferred over raw speed.

⚠️ Multi-Receiver Power Constraints: While the USB-C power option is incredibly useful for saving weight on compact gimbal setups, keep the system's operational constraints in mind. If you are operating the system in its expanded Broadcast Mode (linking 3 to 4 receivers to a single transmitter), the hardware processing requirements increase significantly. In this mode, the hardware cannot draw enough stable current through standard 5V/2A USB-C ports—you must use an NP-F style battery or the locking 12V DC barrel jack to ensure a stable connection.
