Hollyland Cosmo C2 HDMI/SDI Wireless Video Transmission System

Long-Range Wireless Video Transmission for Professional Production
The Hollyland Cosmo C2 Wireless Video Transmission System is designed for filmmakers, broadcasters, and live production teams who need reliable, high-quality wireless video. With a 3000-foot line-of-sight transmission range and ultra-low 33ms latency, this system ensures seamless video monitoring and distribution. The transmitter and receiver kit supports both HDMI and SDI connections, providing flexibility for various production workflows. Whether you're working in a studio or shooting in the field, the Cosmo C2 delivers smooth, uninterrupted video transmission.

Seamless Frequency Hopping with HEVO 2.0 Technology
Operating in the 5.1 to 5.85 GHz frequency bands, the Cosmo C2 uses HEVO 2.0 technology to automatically detect interference and switch to the cleanest available channel. This ensures a stable signal even in congested RF environments, making it ideal for live broadcasts, multi-camera productions, and professional video setups.

Supports UVC, RTMP, and NDI HX for Streaming
The Cosmo C2 is optimized for live streaming with built-in UVC support. A simple USB-C connection allows for direct 1080p60 streaming to a computer without the need for additional capture devices. The system also supports RTMP streaming for direct broadcasting to platforms like YouTube and Twitch. With NDI|HX compatibility, video streams can be transmitted over a single network cable, simplifying production setups and reducing clutter.

FPS Booster for Smooth Frame Rate Conversion
The Cosmo C2 features an advanced frame rate compensation algorithm that converts lower frame rates (1080p24/25/30) into a smooth 1080p60 output. This ensures better motion clarity and improved compatibility with high-frame-rate productions. It also supports fractional frame rate transmission, giving filmmakers greater flexibility when working with different video formats.

Frozen Frame Feature for Broadcast Stability
In the event of a transmission interruption, the Cosmo C2's frozen frame function prevents the display from switching to a manufacturer’s logo. Instead, the last transmitted frame remains on screen, maintaining a professional appearance. Users can also customize the backup frame using a USB flash drive to display a preferred image or logo.

Flexible Power and Mounting Options for Any Setup
Designed for versatility, the transmitter and receiver units offer multiple power options. Both can be powered via DC input using the included power supply, while battery plate options provide portable power solutions. The transmitter features an L-series battery plate, and the receiver includes a V-mount battery plate for extended operation. Each unit also includes 1/4"-20 threads and a cold shoe adapter for easy mounting on cameras, rigs, or stands.
