What this capture card does

The LUOM OZC4 is a USB 3.0 video capturing device that accepts an HDMI signal up to 4K at 30 Hz and records or streams it at 1080p 60 fps. It is built for creators who need a simple way to bring gameplay, camera feeds or presentations into a computer for live broadcasting, recording or online meetings.

How it fits into your setup

Connect the HDMI source to the single input and pass the signal through the HDMI loop-out to a monitor or TV without added latency. The card draws power from the USB 3.0 port and requires no driver installation on Windows, Linux or macOS. A 3.5 mm microphone input lets you add commentary directly into the stream.

Behaviour during long sessions

The aluminium alloy shell acts as a passive heatsink, keeping the latest internal chips stable during extended captures. Hardware-accelerated scaling handles up-scaling and down-scaling without taxing the host CPU, so frame rates stay consistent at 1080p 60 fps. The USB 3.0 link sustains the bandwidth needed for smooth video and clear audio over hours of use.
