Hollyland has tackled the challenges of latency and long-range wireless video transmission with the release of the new Cosmo C2, powered by their new Hevo 2.0 technology. Designed for live streaming, broadcasting, and multi-camera monitoring, the Cosmo C2 claims to deliver crystal-clear video up to 3,000 feet line-of-sight—tripling the range of its predecessor, the Cosmo C1.

Available in multiple configurations, including a two-transmitter, one-receiver kit, a single transmitter-receiver setup, and additional transmitters, the Cosmo C2 offers a flexible solution for professional workflows. At its core, Hevo 2.0 enhances efficiency with intelligent frequency hopping, automatically detecting interference and switching channels in real-time. This ensures rock-solid transmission with latency as low as 33ms, supporting up to 1080p60 resolution.

A standout feature is the built-in FPS Booster, which converts 30 fps HDMI or SDI input to 60 fps, delivering smoother visuals for monitoring. The Cosmo C2 also expands streaming capabilities with embedded UVC for USB-C output, plus RTMP and NDI|HX3 support for seamless, low-latency streaming to professional websites and CDNs.

With dual HDMI and SDI outputs, the receiver supports two transmitters simultaneously, reducing setup complexity. Additionally, on the rare occasion of signal loss, users can replace the default last-frame freeze with a custom logo. Lightweight and ultra-portable, the system is powered via a locking adapter or L-series (TX) and V-mount (RX) batteries, ensuring flexibility for any production environment.

The Hollyland Cosmo C2 2-Transmitter System is priced at $1,299 / £1,200, its one transmitter and receiver kit is priced at $999 / £949, while you can buy a single transmitter for $399 / £379.
