Hollyland Pyro H 4K HDMI Wireless Video Transmission System
Add dependable 4K wireless monitoring to your production with the Hollyland Pyro H. This HDMI transmitter and receiver kit delivers video up to 4K30 with approximately 60 ms latency and a line-of-sight range of up to 1,300 ft, making it well suited to filmmaking, broadcasts, live events, and on-set monitoring.
The transmitter features HDMI input plus an HDMI loop output, so you can monitor the camera feed locally while sending it wirelessly to the receiver. The receiver provides HDMI output for connecting a monitor, switcher, or display.
Pyro H supports flexible multi-viewer workflows. In standard mode, one transmitter can send video to up to two receivers and two mobile devices at distances up to 1,300 ft. Broadcast mode allows one transmitter to connect with up to four receivers at distances up to 650 ft.
Choose HD mode for enhanced image quality with bit rates up to 12 Mb/s, or Smooth mode when lower latency is the priority. Smart channel scanning helps identify cleaner frequencies, while grouping and pairing features streamline setup.
For live streaming and conferencing, UVC support enables plug-and-play video output to compatible computers without a separate capture device. The system can be powered by DC, NP-F batteries, or USB-C power (5–12V), providing versatile options for cameras, gimbals, and mobile rigs.
Included are a wireless transmitter, wireless receiver, five antennas, USB-A to USB-C adapter, and adjustable shoe-mount adapter.
