Hollyland HL-Cosmo C1 Wireless SDI/HDMI Transmission System

Reliable Wireless Video Transmission with HEVO Technology
The Hollyland Cosmo C1 is a high-performance wireless video transmission system featuring HEVO, an advanced transmission protocol that enhances signal stability, reliability, and anti-interference capabilities. Designed for filmmakers, broadcasters, and live production teams, the Cosmo C1 provides a seamless and uninterrupted video experience with ultra-low latency. Say goodbye to signal drops, flickering, and black screens during critical moments of production.

Instant Channel Switching for Continuous Transmission
With adaptive frequency hopping (AFH) technology, the Cosmo C1 ensures automatic channel switching within 0.001 seconds. This rapid adjustment prevents video loss or black screens, keeping your live stream or production feed uninterrupted. Whether in automatic or manual switch mode, the system intelligently selects the best available frequency to maintain a stable connection, even in congested signal environments.

USB-C UVC Support for Direct Live Streaming
The Cosmo C1 simplifies live streaming by integrating USB Video Class (UVC) support. With just a single USB-C cable, users can transmit 1080p60 HD video directly to a computer without the need for a separate video capture device. This plug-and-play functionality eliminates complex setups, making it an ideal solution for live streaming, virtual events, and real-time video monitoring.

Exceptional Low Latency for Precision Monitoring
HEVO technology enhances encoding efficiency by 30% using H.265 (HEVC), ensuring high-quality video with minimal bandwidth consumption. The built-in acceleration module reduces latency to an impressive 0.04 seconds, making the Cosmo C1 an excellent tool for focus pullers and directors who require precise real-time monitoring without delays. With a line-of-sight transmission range of up to 1,000 feet (300 meters), it provides a reliable solution for professional production environments.

Strong Anti-Interference Performance in Any Environment
Designed to withstand challenging RF conditions, the Cosmo C1 features superior anti-interference technology to maintain a strong and clear video signal. Whether operating in busy urban areas, event venues, or remote locations, the system intelligently manages frequency selection to ensure a stable video feed.

Optimized for Professional Production Workflows
The Cosmo C1 is built for versatility, making it compatible with a wide range of cameras, switchers, and live production systems. Its robust build and efficient signal management make it an essential tool for cinematographers, event production teams, and live broadcasters who require dependable wireless video transmission.
