UVC: USB Video Capture, is a pretty nice technology in live broadcast. Note 1. UVC only support 1080P video output now 2. Please set the video format to 1080P on OBS when you add the video capture device.

How to power on the Cosmo C1?

There are 3 ways to power the Cosmo C1 1. DC adapter (6~16V) 2. NPF batteries - [NPF970/NPF750/NPF550] 3. Type-C (5V/2A) (But please don't use it in the working time)

What is the AUTO mode?

Please move the thumbwheel button up and down to change the channel number, the AUTO options are between channels 1 and 8. In the AUTO mode, our device will change the channel to a clean one automatically when there exists interference.

Why does the C1 use a USB cable to connect to the PC to pull the streaming screen through the OBS software abnormally?

At present, the UVC function of the C1 don't support the 1080i format. You need to change the output format of the camera to the 1080p format. The SDI and HDMI interface 1080p and 1080i formats of the C1 are supported, but not including UVC output.
