Hollyland Pyro S HDMI and SDI Wireless Video Transmission System

The Hollyland Pyro S sends video from an HDMI or 3G-SDI source to up to four receivers over 2.4 GHz and 5 GHz, with latency as low as 50 ms.

Range and Modes

The link reaches up to 1,300 feet (400 m) line of sight. Automatic dual-band frequency hopping keeps checking both bands and moves to the clearest channel. HD mode holds a steady 8 to 12 Mbps bitrate at full range, and Smooth mode adjusts the bitrate to keep latency at its lowest.

At startup the Pyro S picks a clear channel on its own, and a smart channel scan on the receiver shows the frequency status. The units come grouped and paired, so the set is ready to use.

Connections

The transmitter has one HDMI input and one 3G-SDI input, and the receiver has one HDMI output and one 3G-SDI output. HDMI carries up to 3840 x 2160 at 30 fps.

In Broadcast mode, one transmitter feeds up to four receivers. With Broadcast mode off, it feeds two receivers and two mobile devices. The Pyro 7 monitor can also serve as a receiver.

Streaming

Over USB-C, the Pyro S works as a UVC device, so a computer takes its video for streaming or video calls without a capture card or extra software. It also streams over RTMP to live platforms through a USB Wi-Fi dongle.

Build and Power

Both units have a magnesium-aluminum alloy shell and a full-color LCD that shows battery level, group, resolution, frame rate, and channel. A two-speed fan runs in an auto mode or a quieter low-speed mode.

Each unit runs on an NP-F battery or DC power from 6 to 16 V, and the set comes with a 12 V/2 A DC power adapter. NP-F batteries are sold separately.

Choosing a Configuration

The Pyro S Set has a transmitter and a receiver. The Transmitter Only and Receiver Only options are single units for building out a system, such as more receivers for one transmitter. The Configurations tab compares the set and the single units.
