There is a small scroll dial that you use to make changes. On the right-hand side of the TX and the RX units is a small-sized OLED display where you can see crucial information and make changes. You also get a small hard case that fits everything inside. The COSMO C1 comes with the following items: I personally think that the COSMO C1 would be more at home on small to mid-sized digital cinema cameras as opposed to mirrorless hybrids.

This weight and size may not make them overly suitable for small-sized cameras. I would say that they are around a similar size to other comparable SDI/HDMI systems. They are not tiny, but nor are they too big. The COSMO C1 RX unit weighs 210g / 7.41oz. Overall I think the COSMO C1 is well made and I think most people will be more than happy with the way it has been constructed. It moves around a little bit when you are using it and this could potentially be something that could break down the track. The On/Off switch is reasonably solid and tactile, however, the scroll wheel feels a little bit on the cheap side. The SDI connectors are slightly recessed, as is the HDMI. The exterior casing feels robust and I wouldn’t think it is likely to break if you dropped it.

I have reviewed a lot of wireless video systems over the years, and the build quality of even the most budget-friendly options has continued to improve. 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. This enables you to use one USB-C cable to send up to 1080 60p video straight into your computer for direct live streaming. The COSMO C1’s parlor trick is that Hollyland has integrated UVC (USB Video Capture). With a large array of ‘affordable’ wireless video transmission systems now flooding the market, Hollyland decided to make something that was a little different.
