Jansicotek OZC4-1 4K USB 3.0 video capturing device 1080p60 loop-out 3.5mm mic

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.
