Jansicotek OZC4-1 capture device

The Jansicotek OZC4-1 is a USB 3.0 video capture device that accepts a 4K HDMI source and records at 1080p 60fps. It is intended for streamers, broadcasters and gamers who need to bring console or camera footage into a computer for live production or recording.

Aluminium body with HDMI loop-through and 3.5 mm

The chassis uses aluminium alloy for durability and heat dissipation. One HDMI 2.0 input and one HDMI output provide 4K 60 Hz passthrough to a display while the USB 3.0 link sends the capture feed to the host. A 3.5 mm microphone input and a 3.5 mm headphone output allow simultaneous voice capture and monitoring without extra adapters.

Passive cooling with low-latency USB 3.0 transfer

No fan is present; the aluminium shell acts as a heatsink for silent operation. The USB 3.0 connection delivers the bandwidth needed for 1080p 60fps capture with minimal latency. Maximum HDMI output resolution reaches 4K 30 Hz when looping to a secondary screen.

Questions about this item

What capture frame rate does the USB 3.0 interface actually deliver?

The USB 3.0 connection captures at up to 1080p 60fps even though the HDMI input accepts 4K@60Hz.

What physical ports must my source and display use to connect this capture device?

One HDMI 2.0 input for the source, one HDMI output for passthrough up to 4K@30Hz, plus 3.5mm microphone input and headphone output.

How do I set up the Jansicotek OZC4-1 and which step do people often miss?

Plug the USB 3.0 cable into the computer, connect the source to HDMI input and the display to HDMI output, then select the device as video and audio source in your streaming software — many forget to choose the 3.5mm ports for mic and headphones.
