Capture card for streamers and gamers

The Jansicotek OZC4-1 captures 4K input at 60fps and records Full HD 1080p at 60fps over USB 3.0. It provides an HDMI loop-out up to 4K@30Hz or 1080p@120Hz for simultaneous monitoring. The device suits creators streaming to OBS, Twitch, YouTube or TikTok from consoles, PCs or DSLR cameras.

Thermals noise and power draw

The compact unit draws power directly from the USB 3.0 connection without an external adapter. Passive cooling keeps operation silent during extended sessions. Low power consumption means no additional strain on laptop or desktop ports while capturing high-resolution footage.

Bundled audio ports change the workflow

Built-in 3.5mm microphone input and headphone output let you mix live commentary and monitor game audio without a separate interface. This simplifies single-PC streaming setups and reduces cable clutter for podcasters or educators recording voiceovers alongside gameplay.

Questions about this item

How do I connect the Jansicotek OZC4-1 so gameplay shows on my monitor while the PC records?

Connect the console HDMI to the card input, the card HDMI output to the monitor, and the USB 3.0 cable to the PC. The common mistake is plugging the monitor into the PC instead of the card loop-out, which breaks the 4K@30Hz passthrough.

Which parts of the Jansicotek OZC4-1 might wear out and need replacement later?

The 3.5mm microphone and headphone jacks see repeated plug cycles and can loosen over time. The USB 3.0 cable and HDMI ports are also physical connectors that may need replacement if damaged, but the capture chip itself has no moving parts.

What resolution limit appears first when I stream for hours with the Jansicotek OZC4-1?

The capture path tops out at 1080p@60fps over USB 3.0, so sustained streaming locks you to Full HD even though the HDMI input accepts 4K and the loop-out can pass 4K@30Hz to a display.
