Fuel Your Connections
Pryo H, your ultimate HDMI-only solution specially designed for video transmission at up to 4K/30fps, is now available on the market. With transmission over dual 2.4 GHz and 5 GHz frequency bands, this innovative kit marks Hollyland’s pioneering leap into the realm of 4-receiver support, offering enhanced monitoring stability and collaboration on set. With a new level of performance in transmission range, and latency, among other things, Pyro H is to make a difference.

• Up to 1,300′ (400m)
• 0.06s Low Latency
• 2.4 GHz & 5 GHz Dual Band
• 4K30 Transmission

4 Receivers. Not an Issue.
Pyro H’s Wi-Fi Broadcast technology enables one transmitter to connect to four receivers with stable signals, offering more flexibility when additional monitoring needs emerge on set. When Broadcast mode is activated, the transmitter can transmit signals to at most four receivers, and the LOS range reaches 650ft (200m). When Broadcast mode is deactivated, the transmitter can transmit signals to at most two receivers and two mobile devices, and the LOS range extends up to 1,300ft (400m).

Faster. Longer. Stronger.
With self-developed 2.4 GHz & 5 GHz Dual-Band technology, Pyro H features a stable transmission range of up to 1,300ft (400m) and a latency of as low as 60ms. Compared to Mars series whose transmission range extends at the cost of image quality and latency, Pyro H excels with increased transmission distance while preserving video quality and minimizing latency. The kit also provides two modes for users to tip the balance between image quality and latency, with HD mode for better image quality with bitrate at up to 12 Mbps and Smooth mode for a dynamic change in latency.

4K. Crisp and Sharp.
With 4k/30fps transmission capabilities, Pyro H presents images with superior clarity, detail, and realism, making it competent for professional applications, such as filmmaking.

HDMI Loopout Support.
HDMI Loopout port allows the output of signals to another display device, such as a monitor, without compromising the quality of the transmitted signal, which enables users to conveniently monitor the transmitted content, and make adjustments as necessary.

USB Video Class.
UVC allows seamless compatibility with a wide range of devices, such as computers, without requiring additional drivers or software installations. This plug-and-play feature simplifies setup and operation, making it convenient for users in various scenarios such as live streaming and video conferencing.

Smart Channel Scan.
Upon startup, Pyro H automatically chooses a high-quality frequency channel, optimizing the user experience from the outset. Additionally, users can activate the smart channel scan function on the receiver to view real-time feedback on the frequency status, thus ensuring an uninterrupted and reliable experience.

Easy Setup. Ready to Go.
Pyro H supports preset grouping and pairing, obviating the need for users to repetitively and manually set up the transmitter and receivers. Time matters to content creators. What matters to you matters to Hollyland.

USB-C Charging. Continuous Power.
In addition to DC and NP-F batteries, Pyro H also supports USB-C power supply (5-12V). This power supply option proves convenient, especially when using stabilizers, as it eliminates the need for NP-F batteries, thus reducing overall weight and enhancing maneuverability.
