Hollyland Cosmo C1 SDI/HDMI Wireless Video Transmission System

The Hollyland Cosmo C1 is a professional SDI/HDMI wireless video transmission system designed for filmmakers, live event teams, churches, studios, broadcast crews, and content creators who need stable wireless camera monitoring.

It allows you to send high-quality video from a camera to a monitor, switcher, recorder, or computer without running long HDMI or SDI cables. The system supports up to 1080p60 video transmission through HDMI and SDI, making it suitable for professional Full HD production workflows. Hollyland lists the Cosmo C1 with HDMI/SDI input and HDMI or dual SDI output support.

Reliable Long-Range Wireless Transmission

The Hollyland Cosmo C1 is built for stable wireless video monitoring over long distances. It can transmit video up to 1000ft line of sight with low latency of about 40ms, which helps production teams monitor live footage with minimal delay. B&H also lists the system as operating on the 5GHz frequency band with HEVC/H.265 transmission technology.

This makes it ideal for weddings, concerts, church livestreams, conferences, outdoor filming, studio work, and broadcast environments.

SDI and HDMI for Professional Setups

The Hollyland Cosmo C1 supports both HDMI and SDI connections, giving users more flexibility with different cameras and production equipment. The transmitter supports HDMI and SDI input, while the receiver supports HDMI and SDI output. Hollyland also notes that the transmitter includes SDI loopout, which is useful when you want to connect another monitor or production device at the camera side.

USB-C Livestreaming Support

For livestreaming, the Cosmo C1 includes embedded UVC over USB-C, allowing 1080p60 video to be sent directly to a computer without needing a separate capture card for supported progressive signals. This is useful for churches, online events, training sessions, video calls, and live production workflows.

Stable Signal for Live Production

The system supports smart channel selection and adaptive frequency technology to help maintain a cleaner wireless signal in busy environments. It is a strong choice for crews who need dependable video monitoring during live work, where signal stability and low delay are important.
