BZBGear BG-12GCSA 12G-SDI Capture Box
The 12GCSA puts a 12G-SDI camera into a laptop over USB-C, which is the part of a broadcast chain that usually needs a PCIe card and a desktop. It appears as a standard capture device to OBS, vMix, Zoom, Teams and the rest, delivering up to 4K30 or 1080p120 over the USB connection.
Because it also has an HDMI output and an SDI loop-out running at up to 4K60, the same box feeds a local monitor and passes the signal on to a switcher. Audio can come from the SDI embed or a 3.5 mm stereo input, and there are 3.5 mm and TOSLINK outputs for monitoring. Cable equalisation reaches 30 m on the 12G input and 200 m at 3G.
