Hollyland Cosmo C1

The wireless architecture of the Cosmo C1 is based on HEVO technology with Adaptive Frequency Hopping (AFH), which improves link stability and interference resistance within the 5.1–5.8 GHz band, reducing signal drops and flickering even in complex environments. This system offers HDMI and 3GSDI interfaces on both the transmitter and receiver, including SDI loopout on the transmitter unit to feed auxiliary monitors without additional hardware. A notable feature is the integrated UVC, which allows the video signal to be sent directly to a computer via a USB-C cable as if it were a webcam, ideal for streaming or recording production without the need for an external capture card. The Cosmo C1 integrates OLED status displays on both modules for easy reading of settings and link status, and is compatible with various power sources—including L-series battery plates, 616V DC power, and USB-C, making it versatile for both studio and outdoor shoots.
