Gefen EXT-DVIKA-HBT2 DVI KVM HDBaseT 2.0 Extender with USB, RS-232, 2-Way Audio, and POH

For long‑run AV, security and monitoring installations that require reliable video, control and audio over a single cable, the Gefen DVI KVM HDBaseT 2.0 Extender delivers a complete remote workstation solution. This HDBaseT 2.0 (Colligo) extender transports DVI video — and with Gefen DVI‑to‑HDMI cabling, HDMI formats up to 4K (4096x2160 @30Hz 4:4:4 or 3840x2160 @60Hz 4:2:0) — across a single CAT‑5e/6 cable up to 495 feet (150 m), while also extending USB, RS‑232 and two‑way analog audio for keyboards, mice, microphones and powered speakers.

POH (Power Over HDBaseT) lets you power the Sender from the Receiver over the same cable, minimizing equipment at remote camera or console locations. Support for 7.1 LPCM and HBR audio formats (Dolby Atmos®, DTS:X, etc.) ensures full‑featured AV playback for control rooms and surveillance monitoring. Gefen Syner‑G software provides EDID management, link monitoring and firmware updates to simplify commissioning in enterprise and security networks.

Ideal for security, surveillance, broadcast and AV control centers that need dependable, low‑latency extension and streamlined installations. Add the EXT‑DVIKA‑HBT2 to your next networked monitoring project or contact sales for a site‑specific recommendation.
