Hollyland Cosmo C2 Wireless Video Transmission System

The Cosmo C2 is the long-range end of Hollyland's video line: 1000m (3,000ft) of line of sight at 0.033 seconds of latency, which puts a monitor across a stadium or a car-to-car rig within reach. HEVO 2.0 seamless frequency hopping moves the link without a visible break, rather than dropping and reacquiring.

What separates it from the Pyro line is the network side. It outputs NDI HX3, so the wireless feed lands directly on an NDI switcher as a source with no receiver hardware in the vision chain, alongside UVC and RTMP streaming. Two transmitters can share a single receiver, and it carries both HDMI and SDI, fractional frame rate support and an FPS booster, transmitting 1080p.
