Hollyland Cosmo C2 HDMI/SDI — Wireless Video TX/RX Set

Up to 1080p60 — 3000 ft (914.4 m) LOS — HEVO 2.0 — 33ms Latency — UVC/RTMP/NDI|HX — HDMI + SDI

Overview

The Hollyland Cosmo C2 HDMI/SDI wireless video transmission system lets you send high-quality video up to 1080p60 over long distances up to 3000 ft / 914.4 m line-of-sight to a single receiver—ideal for flexible monitoring and signal distribution on set or in the studio.

Operating across 5.1 to 5.85 GHz, it features HEVO 2.0 intelligent frequency hopping for cleaner channels and delivers low-latency performance at 33 ms. It also supports UVC (computer capture/streaming), RTMP live streaming, and NDI|HX over Ethernet via the receiver, plus FPS Booster frame-rate conversion for smoother 1080p60 output.

Have you ever wondered ..? 

Why Cosmo C2 earns a spot in your workflow

Long cable runs slow crews down and clutter sets. Cosmo C2 gives you a stable, long-range wireless link with low latency—so directors, focus pullers, and video villages can monitor confidently while operators stay mobile.

And it’s not just monitoring: with UVC, RTMP, and NDI|HX support, it can bridge production and streaming needs—making it a versatile, “one system, many jobs” solution.
