LUOM OZC7 4x1 HDMI video capturing device 4K@30Hz USB 3.0 seamless switch recording screen device

Four-input HDMI switch and capture

The LUOM OZC7 is a 4x1 HDMI video capturing device built for streamers, educators and conference hosts who need to juggle multiple sources. Four HDMI inputs and a dedicated microphone port feed a single USB 3.0 output for recording or broadcasting at up to 1080@60fps. An HDMI loop-out passes 4K@30Hz through to a local display without added latency. No driver installation is required; the unit works with standard third-party software such as OBS.

Metal chassis with IR remote and LED status

A compact black enclosure houses the switching logic and connectivity, measuring 4.45 x 2.2 x .71 inches and weighing .352 ounces. Four HDMI inputs, one microphone jack, one USB 3.0 port, one HDMI output and one audio output are arranged along the edges for tidy cable routing. An included IR remote lets you change sources from across the room, while a front-panel LED indicator confirms the active input at a glance. Both USB-A and USB-C cables are supplied for host compatibility.

Passive cooling keeps operation silent

The device draws power directly from the USB 3.0 connection and uses no fan, so it adds no audible noise to a recording environment. HDMI 1.4 pass-through handles 4K@30Hz video and LPCM audio without frame drops, while the USB capture path delivers YUY2, RGB24 or MJPEG encoded streams at 1080@60fps. Low power draw and passive thermals make it suitable for extended live sessions or unattended conference deployments.
