Hollyland COSMO C1 Review – Newsshooter

The COSMO C1 is the latest addition to the COSMO series. The key selling point for the COSMO C1 is that it is the industry’s first wireless video system to integrate a UVC (USB Video Capture) interface. This allows the COSMO C1 to offer a simplified solution for streaming and cloud-sharing video.

According to Hollyland, the COSMO C1 offers real-time video monitoring up to 1,000ft line-of-sight. It also incorporates boosted signal strength, better anti-interference capability in the 5.1GHz-5.8GHz frequency spectrum.

With a large array of ‘affordable’ wireless video transmission systems now flooding the market, Hollyland decided to make something that was a little different. The COSMO C1’s parlor trick is that Hollyland has integrated UVC (USB Video Capture). This enables you to use one USB-C cable to send up to 1080 60p video straight into your computer for direct live streaming. You don’t need to use any type of video capture device as the input will be recognized by your computer as a webcam source.
