Hollyland launches the Cosmo C2, an advanced wireless video transmission system designed for seamless multi-camera live streaming. Engineered for video professionals, the Cosmo C2 enhances efficiency, reliability, and workflow simplicity.A key highlight of the Cosmo C2 is its dual-transmitter, single-receiver setup, which overcomes traditional 1TX-1RX limitations such as excessive cabling, spatial constraints, and synchronization delays. This feature allows two cameras to wirelessly transmit signals to a single receiver, streamlining setup and ensuring precise synchronization across multiple camera feeds.Designed for professional live event production, the Cosmo C2 offers an impressive 1,000-meter line-of-sight wireless transmission range and a 300-meter back-to-back transmission range, preventing signal dropouts and ensuring smooth visuals. With Its ultra-low latency of 33ms it significantly improves synchronization, outperforming the typical 60ms benchmark that often causes misalignment in LED-based live events. This makes it an ideal solution for high-stakes productions where real-time precision is crucial.Hollyland’s HEVO2.0 technology ensures stable transmission, automatically detecting and switching to interference-free channels to maintain seamless video feeds. Additionally, the Cosmo C2’s receiver features a new frame rate compensation algorithm, converting low frame rate inputs to 60P for enhanced visual fluidity. A last-frame retention feature ensures that if a signal is lost, the last transmitted frame remains on-screen instead of displaying manufacturer logos—critical for professional, uninterrupted broadcasts.The Cosmo C2 simplifies video transmission by integrating NDI, UVC, and RTMP support directly into its receiver. NDI compatibility enables direct local area network video streaming without the need for additional converters. UVC support allows direct USB-C streaming without a capture card. RTMP functionality enables cloud-based live streaming, eliminating reliance on external devices for real-time broadcasts.
