Compact 4K HDMI capture for streamers

The Jansicotek OZC3-1 accepts HDMI input up to 4196x2160 at 60Hz from consoles, cameras or laptops and passes the signal through its HDMI loop-out at the same resolutions. USB capture tops out at 1920x1080 at 30fps for streaming or recording. A 3.5 mm microphone input and stereo output are built in for live commentary.

Thermals noise and power in daily use

The device draws power directly from the USB 3.0 connection with no external adapter required. Its small aluminium body runs cool during extended sessions and operates silently because it has no moving parts. Power consumption stays low enough for laptop ports without throttling.

Bundled accessories and software impact

No driver installation is needed; the card appears as a standard UVC device in OBS, Zoom or any compatible application on Windows, macOS or Linux. The package supplies only the capture unit and a short USB 3.0 cable, so users provide their own HDMI cables and microphone.

Questions about this item

How do I install the Jansicotek OZC3-1 capture card and what step is often missed?

Connect the source to the HDMI input, the display to the HDMI output, the USB 3.0 port to the PC, and the 3.5 mm microphone if needed; the step often missed is selecting the USB video device in OBS or streaming software before going live.

What maintenance or replacement will the Jansicotek OZC3-1 need later?

No internal parts require scheduled replacement; keep the HDMI and USB connectors dust-free, check the 3.5 mm ports for debris, and replace cables only if they become damaged or loose.

What limit appears first during sustained use of the Jansicotek OZC3-1?

The USB capture path caps at 1080p30 while the HDMI loop-out continues at up to 4K60, so extended sessions are limited by the 1080p30 encoding ceiling rather than thermal throttling.
