Cosmo C2 is a long-range wireless video system that lets two transmitters feed a single dual-channel receiver. This 2TX-to-1RX architecture reduces the amount of equipment and cabling in multi-camera live production and keeps the two video feeds well synchronised.
Using Hollyland’s HEVO 2.0 technology with seamless frequency hopping, Cosmo C2 reaches up to 1,000 m (3,000 ft) line of sight with latency as low as 33 ms. The receiver provides two HDMI and two SDI outputs plus an Ethernet port for NDI|HX3, and both UVC and RTMP streaming are supported, making it a strong fit for broadcast and multi-camera live streaming.
