The Hollyland Cosmo C2 represents a revolution in wireless video transmission technology, engineered by industry experts to meet the demands of professional filmmakers, broadcasters, and content creators. This powerful system features a groundbreaking 2TX & 1RX design that enables seamless transmission between two transmitters and one receiver, significantly reducing equipment clutter and simplifying your production workflow.

With its remarkable 3,000ft (1,000m) line-of-sight transmission range and ultra-low 33ms latency, the Cosmo C2 ensures your video feeds remain stable and synchronized even in challenging environments. The innovative HEVO 2.0 technology automatically detects surrounding frequency interference and seamlessly switches to clean channels, guaranteeing uninterrupted transmission with no black screens or signal drops during crucial moments.

The Cosmo C2 goes beyond simple transmission by integrating advanced streaming capabilities. Support for NDI protocol allows video streams to be transmitted over a single network cable, while UVC streaming enables direct connection to computers without capture cards. RTMP streaming functionality provides compatibility with popular platforms like YouTube and Twitch, making this system a versatile solution for both live productions and professional filming environments.

Key Features

• Enables transmission between two transmitters and one receiver: This innovative setup reduces equipment needs, minimizes wireless interference, and ensures better synchronization between multiple video feeds, creating a more streamlined and productive workflow for multi-camera productions.
• 33ms ultra-low latency and up to 3,000ft line of sight (LOS) range: Experience exceptional transmission performance with minimal delay that remains consistent even over extended distances. The system's impressive range makes it perfect for large venues, outdoor shoots, and complex production environments.
• Support NDI & UVC & RTMP Streaming: The versatile Cosmo C2 supports Network Device Interface (NDI) protocol for streamlined network transmission, USB Video Class (UVC) streaming via direct USB-C connection, and Real-Time Messaging Protocol (RTMP) for direct streaming to platforms like YouTube and Twitch.
• Features HDMI and SDI inputs and outputs, including conversion and loopout capabilities: Comprehensive connectivity options include HDMI and SDI inputs on transmitters with SDI loopout, plus dual HDMI and SDI outputs on the receiver. This flexibility ensures compatibility with virtually any professional camera, monitor, or production equipment.
• Compatible with DC, NP-F, V-Mount batteries, DC adapter: Multiple power options keep your production running smoothly. Transmitters support DC power and NP-F batteries, while the receiver works with DC power and V-Mount batteries, providing flexibility for both studio and field applications.
• The receiver utilizes a cutting-edge frame rate compensation algorithm: Convert 24/25/30p inputs to smoother 60p outputs with the innovative FPS Booster feature, enhancing visual quality without requiring additional processing equipment.
