Hollyland Cosmo C2 Overview

The Cosmo C2 HDMI/SDI Wireless Video Transmission System from Hollyland allows you to wirelessly transmit high-resolution video up to 1080p60 over long distances up to 3000' to a single receiver, allowing flexible video monitoring and distribution for your studio or field production. This kit comprises a transmitter and a receiver that communicate over the 5.1 to 5.85 GHz wireless frequency range. Additional improvements to the series include HEVO 2.0 technology, UVC/RTMP/NDI|HX streaming support, and expanded power options.

Strong Signal Strength, Seamless Frequency Hopping

The Cosmo C2 can transmit 1080p60 video up to 3000' line-of-sight with a low 33 ms latency. The system operates on the 5 GHz frequency band, automatically detecting surrounding frequency interference and seamlessly switching to a clean channel via HEVO 2.0 technology. This makes for an uninterrupted transmission signal.

Connectivity

  • The transmitter features one HDMI input, one SDI input, and one SDI loop output.
  • The receiver features two HDMI outputs, two SDI outputs, and an RJ45 Ethernet port.
  • USB-C ports on both units allow you to connect to the included USB-C OTG adapter and your personal computer for UVC streaming.

RTMP and NDI|HX Streaming

The Cosmo C2 unlocks RTMP streaming for direct live streaming to YouTube, Twitch, and other platforms. The receiver unit supports NDI|HX protocol, transmitting video streams via a single network cable for a cleaner production space.

FPS Booster, Fractional Frame Rate

Using a frame rate compensation algorithm, the Cosmo C2 receiver can convert low frame rate inputs like 1080p24/25/30 to high frame rate outputs at 1080p60, making smoother visuals. The Cosmo C2 can also transmit HDMI/SDI fractional frame rate input/output signals to ensure flexibility while filming.

Frozen Frame

If your transmission is interrupted, Cosmo C2 can freeze the last frame of your feed, effectively preventing the display of the manufacturer's logo. There is also the option to customize the logo image if you prefer to use a USB flash drive for a more professional appearance.

Versatile Power and Mounting Options

Each unit can be powered via DC input using the included power supply when working on set. In field applications or in studio spaces with limited outlets, both units offer battery plate options. The transmitter features an L-series battery plate, and the receiver features a V-mount battery plate for higher-capacity power sources. Use the 1/4"-20 threads on the units or the cold shoe adapter to secure them to the mounting configurations of your choice.
