Description
The Hollyland Cosmo C2 HDMI/SDI wireless video transmission system is designed to transmit high-resolution video up to 1080p60. It boasts an ultra-long LOS range of 1,000m and a super-low latency of just 33ms. Featuring the newly developed HEVO 2.0 technology that is 18% faster and features up to 186% greater range over HEVO 1.0 with automatic frequency hopping to ensure uninterrupted transmission over the 5.1 to 5.85GHz range. Combined with other powerful features and functions like NDI, UVC and RTMP streaming, this innovative kit will prove to be a great help for multi-camera livestreaming, broadcast, and more.
configurations
The Cosmo C2 can transmit signals using up to two transmitters and one receiver. This configuration minimises the number of devices and cables required, reduces wireless interference, and ensures better synchronisation of video feeds. Together, these advantages contribute to a more efficient workflow.
More Range, Less Latency
1,000m (3,000ft) Range
Cosmo C2 boasts an ultra-long line-of-sight (LOS) transmission range of up to 1,000m (3,000ft), making it ideal for professional use in large venues, open areas, and complex buildings.
33ms latency
Cosmo C2 achieves a super-low latency of just 33ms, and the latency remains the same over extended distances, thus ensuring smooth and reliable transmission.

Seamless Frequency Hopping
Powered by self-developed HEVO 2.0 technology, Cosmo C2 automatically detects surrounding frequency interference and seamlessly switches to a clean channel, which ensures uninterrupted transmission and an immersive experience
UVC
Cosmo C2 supports UVC streaming as well. With a USB-C to USB-C or USB-C to USB-A cable, you can directly connect the receiver to any computer without the need for capture cards, simplifying the real-time transmission of on-site video.
Improve Your Workflow
The receiver of Cosmo C2 supports Network Device Interface (NDI) protocol, allowing video streams to be transmitted over a single network cable. This eliminates the complexity and clutter of connections and creates a cleaner production space.
frame rate compensation
Through a brand-new frame rate compensation algorithm, the RX can convert low frame rate inputs such as 24/25/30p to a high frame rate output at 60p, making the visuals smoother
