Jansicotek OZC4-1 capture card

The Jansicotek OZC4-1 is a USB 3.0 video capture device that accepts 4K HDMI input and delivers up to 1080p60 footage to a computer for streaming or recording. It includes an HDMI loop-out for simultaneous display on a monitor or projector and a 3.5 mm microphone input for live commentary. The compact black unit suits streamers, educators and content creators who need a simple plug-and-play capture solution.

Sustained 1080p60 capture behaviour

During extended sessions the device maintains a steady 1080p 60 fps stream over USB 3.0 without dropping frames, while the HDMI loop-out continues to pass a 4K 30 Hz signal to an external screen. The constant data throughput keeps encoding workloads predictable for broadcasting software. Users who require higher capture frame rates or 4K recording will need a different capture device.

Thermals noise and power draw

The capture card draws power directly from the USB 3.0 connection and runs without a fan, so it adds no audible noise to a streaming setup. Its aluminium casing dissipates heat passively during typical multi-hour broadcasts. No external power adapter is required, keeping cable clutter to a minimum.

Questions about this item

Does the Jansicotek OZC4-1 get hot or noisy when I stream all day?

The capture card has no fan and draws power from the USB 3.0 port, so it runs silently and stays cool during extended sessions.

What must I already own to use the 3.5 mm mic input and headphone output?

You need a 3.5 mm microphone for commentary and a 3.5 mm headset or speakers for monitoring; the card provides the ports but not the accessories.

Will my older 1080p60 monitor work with the HDMI loop-out while I capture at 1080p60?

Yes, the loop-out passes the incoming signal up to 4K at 30 Hz, so a 1080p60 display works without any scaling issues.
