Hollyland Pyro Ultra 1TX & 2RX Wireless Video Transmission System

Hollyland Pyro Ultra wireless video transmission system in a kit with one transmitter and two receivers. It transmits true 4K60 over HDMI and up to 1080p60 over 3G-SDI, up to 1.5 km line of sight, with latency from 20 ms in Focus Mode. The kit is ready for two monitors, for example for the director and the focus puller, and in Broadcast Mode you can add more receivers.

Cable-free 4K60 for the whole crew

One transmitter on the camera, two receivers at the monitors and TWiFi technology that merges the 2.4 GHz and 5 GHz bands into a single resilient link.

4K60 / 12 Mbpsup to 1.5 kmfrom 20 msHDMI + 3G-SDI

One transmitter, unlimited receivers

In Broadcast Mode the transmitter serves any number of receivers, with stable operation guaranteed for up to 20. The standard setup offers 6 monitoring screens: 4 receivers and 2 mobile apps.

Focus without waiting

Focus Mode reduces latency to 20 ms at 1080p25/30, 40 ms at 1080p60 and 45 ms at 4K60.

Pyro ecosystem

The kit works with Pyro H, Pyro S, Pyro 7, Pyro 5 and Vcore, so your existing gear stays in use.

Broadcast Mode

TWiFi technology lets one transmitter connect an unlimited number of receivers with smooth, stable images. Stable operation is ensured with up to 20 receivers; additional connections depend on the environment. Range is up to 700 m in Broadcast Mode and up to 1.5 km outside it.

True 4K60 at 12 Mbps

Pyro Ultra transmits true 4K at 60 frames per second over HDMI at a bitrate of 12 Mbps. The TWiFi codec preserves detail, subtle gradations and depth.

Focus Mode for focus pullers

With Focus Mode enabled, latency on the enabled receivers drops to as low as 20 ms, so every focus pull responds instantly. The mode can be enabled on all receivers in a group at once, while the other monitors keep running unchanged.

Proprietary TWiFi technology

TWiFi combines the 2.4 GHz and 5 GHz bands into a single composite link that is more resilient than conventional dual-band transmission. Automatic frequency hopping avoids congested channels without manual intervention.

DFS channels

Pyro Ultra supports Dynamic Frequency Selection (DFS) bands, unlocking more spectrum for transmission in regulated regions. Frequency availability depends on local regulations.

UVC and RTMP streaming

The receiver connects to a computer over USB-C as a UVC capture device up to 4K60. Direct RTMP streaming handles up to 1080p60 for live production and remote collaboration.

The whole Pyro ecosystem

Pyro Ultra works with Pyro 5 and Pyro 7 in both Broadcast and non-Broadcast Mode, and with Pyro H and Vcore in non-Broadcast Mode. Pyro S currently supports non-Broadcast Mode only; Broadcast support will come with a firmware update.

Freeze frame and custom logo

If the signal drops, the last frame stays on the monitor so the crew never loses the picture. A custom 1920 × 1080 image (JPG under 1 MB named logo.jpg) can be shown instead.
