INOGENI 4KXUSB3 — 4K HDMI to USB 3.0 professional camera converter
The INOGENI 4KXUSB3 is a professional-grade 4K Ultra HD HDMI to USB 3.0 camera converter designed for AV integrators deploying video conferencing, recording and streaming solutions. It bridges any HDMI camera — including professional PTZ models from Vaddio, Aver and Marshall — into any USB-based platform such as Microsoft Teams, Zoom, Google Meet or Webex, without requiring driver installation. Compact and bus-powered, it fits discreetly in any meeting room or AV rack, and its HDMI loop output keeps a local display active while the signal is simultaneously captured. Certified for Zoom Rooms and compatible with Barco ClickShare Conference, Logitech UC CODECs and Crestron AutoTracker, it is a reliable, TAA-compliant converter designed and manufactured in Canada.
True Plug-and-Play on All Major OS
The 4KXUSB3 requires no driver installation whatsoever and works immediately on Windows 7+, macOS 10.10+ and Linux (kernel v2.6.38), as well as Android. It is UVC-compliant, meaning it is recognised by every DirectShow, AVFoundation and V4L2-compatible application right out of the box. In practice this dramatically cuts deployment time and eliminates the most common on-site frustration — a converter that refuses to work with a specific laptop chipset. Because it is also compatible with all USB 3.0 motherboard chipsets (Intel, Renesas, ASMedia, Fresco Logic), installers do not need to pre-qualify the host machine before arrival.
HDMI Loop-Through Keeps Local Display Live
A dedicated HDMI 1.4a loop output passes the camera signal through to a local monitor simultaneously with USB capture. This is a critical differentiator in meeting-room installs: the room display or confidence monitor stays active with the full-quality HDMI feed while the laptop captures via USB, without any signal splitting box or additional cabling. The loop also carries HDMI-CEC passthrough, preserving any CEC-based control chain already in the room.
VISCA RS-232 PTZ Camera Control over USB
A built-in terminal-block VISCA port (RS-232, 9600 bps) lets the host PC send pan/tilt/zoom commands and recall camera presets over the same USB connection used for video. This is what separates the 4KXUSB3 from simpler capture cards: integrators can bring professional PTZ cameras from brands like Vaddio, Aver or Marshall into a Zoom Rooms or Teams room and retain full remote camera control from the conference software — no separate serial adapter or control processor required. Crestron AutoTracker and AutoFramer are certified with this VISCA implementation for Zoom Rooms deployments.
Flexible Audio: HDMI Embedded + Analog I/O
Beyond HDMI embedded audio (2-channel 48 kHz LPCM), the 4KXUSB3 adds a 3.5 mm analog audio input (mic or line-level) and a 3.5 mm analog output (line-level). The device internally mixes HDMI audio and analog audio across both the USB and analog paths, with the exact routing configurable via INOGENI's Control App. This makes it practical to integrate a room microphone or analogue audio source without an external audio interface — the host sees a single USB audio device combining all sources.
Broad UC Platform & Hardware Certification
The 4KXUSB3 is Zoom Rooms certified and validated against Barco ClickShare Conference (CX-20, CX-30, CX-50), Logitech UC CODECs (Rally Bar series, Roommate) and Crestron AutoTracker/AutoFramer. This matters because enterprise IT departments increasingly mandate certified hardware to ensure support and warranty coverage — having the certifications removes that procurement barrier. The device is also TAA-compliant, qualifying it for US federal and government procurement alongside commercial deployments.
Bus-Powered Compact Form Factor
At just 9.9 × 7.4 × 1.9 cm and 140 g, the 4KXUSB3 draws all its power directly from the USB 3.0 port (5 V, 900 mA) — no power adapter or nearby outlet is needed. This is genuinely useful in meeting rooms and huddle spaces where power access near the AV cabinet is limited, and it keeps the cable count to a minimum. A 3 ft USB 3.0 Type-A to Type-B cable and an RS-232 terminal block adapter are included in the box.
