The Hollyland Cosmo C2 (1TX & 1RX) is a single transmitter and receiver wireless video transmission system, purpose-built for reliable studio and field monitoring on one camera. Onboard HEVO 2.0 technology provides seamless frequency hopping for superior anti-interference performance across long distances.
With a line-of-sight range of up to 1,000m (3,000ft) and just 33ms latency, the Cosmo C2 keeps visuals clear and consistent throughout production. The receiver’s frame rate compensation algorithm converts 24/25/30P inputs to a smoother 60P output, and supports NDI over a single network cable, along with UVC and RTMP streaming.
Both transmitter and receiver feature HDMI and SDI input/output plus USB-C connectivity, with expanded power options for flexible on-set setups.
