• HDMI Input and HDMI Loop Output
• 2.4 and 5 GHz Frequency Bands

The Pyro H is a professional-grade transmitter designed for filmmakers and broadcast crews who need reliable wireless video. It accepts an HDMI input and provides an HDMI loop output so you can feed a local monitor while sending the same signal wirelessly. The unit operates on both 2.4 and 5 GHz bands to give you flexibility in crowded RF environments.

Long Distance, High Quality Transmission

The Pyro H transmits UHD 4K at 30 fps and supports long line-of-sight ranges. When Broadcast mode is deactivated, a single transmitter can send signals to up to two receivers and two mobile devices, with a line-of-sight range up to 400 m. When Broadcast mode is activated, the system supports up to four receivers, with a line-of-sight range reaching 200 m. These modes let you choose between wider range or broader multi-receiver monitoring depending on your setup.

Strong Signal Strength and Low Latency

The Pyro H delivers latency as low as 60 ms while maintaining transmission stability. The system offers selectable modes so you can prioritize image quality or lower latency depending on your needs. In HD mode, the system supports higher image quality with bitrates up to 12 Mb/s. In Smooth mode, the transmitter adjusts for dynamic latency changes to keep monitoring responsive during active shoots.

Crisp Image Support

With support for up to UHD 4K at 30 fps, the Pyro H transmits detailed and realistic images suitable for professional broadcast and filmmaking use. It also supports a range of HD and interlaced formats for compatibility with diverse cameras and monitors.

USB Video Class (UVC) and Power Options

The Pyro H includes a USB-C port that supports UVC plug-and-play operation. This allows you to connect the transmitter to a computer and use the wireless video stream directly for streaming or conferencing without additional drivers. The USB-C port can also power the unit. Alternatively, the unit accepts a locking DC barrel input and can be powered by an L-series type battery via an optional battery plate (battery plate sold separately). This variety of power options helps you integrate the transmitter into gimbals, cameras, and studio rigs with ease.

Smart Channel Scan and Easy Setup

The built-in frequency scanner helps you choose the clearest transmission channel. On startup, the Pyro H can automatically select a high-quality frequency, and the receiver can perform a smart channel scan to show real-time frequency status. Additionally, the unit supports preset grouping and pairing to streamline repeated setups and reduce time spent manually pairing transmitters and receivers on set.

Additional Practical Details

The transmitter offers two RP-SMA antenna connections and a bright LCD screen for configuration. It supports Wi‑Fi 4 (802.11n) dual-band operation on 2.4 and 5 GHz, and it is compatible with mobile apps on Android and iOS for convenient monitoring and control. Timecode support is included, and the wireless video uses uncompressed transmission.
