Belkin Secure Universal 4-Port KVM Switch with Audio

The Belkin F1DN104KVMUN3 is a secure KVM switch that provides four ports and integrated audio, allowing you to operate up to four computers with a single keyboard, mouse, monitor, and set of speakers.

Engineered for departments that manage sensitive or classified information, the switch meets NIAP PP3.0 security requirements and is TAA compliant. This level of assurance makes it a reliable choice for government agencies, military installations, healthcare networks, and any workplace where strict security policies are enforced.

Each of the four inputs can accept DVI, DisplayPort, or HDMI signals. The switch detects the signal type automatically, so you can mix different workstations without adapters or manual configuration. Support for resolutions up to 4K at 60Hz delivers sharp, detailed visuals and keeps the setup ready for future display upgrades.

Inside the unit, all signal paths remain isolated from one another. Keyboard, mouse, video, and audio channels do not cross, which mitigates the risk of data leakage between systems operating at different security levels.

The chassis is built from metal that resists tampering, and passive cabling reduces points of failure while simplifying upgrades. Optional mounting accessories let you position the switch on a desk, in a rack, or under a console for a clean, organized workspace.

In daily use, the F1DN104KVMUN3 streamlines complex workflows. An administrator can jump between classified and unclassified networks, a radiologist can compare imaging data from multiple machines, and a financial analyst can evaluate information on isolated computers, all without unplugging peripherals or adding extra monitors.

Because the switch works with standard USB keyboards, mice, and headsets, you can keep the equipment you prefer and stay focused on your tasks instead of managing cables.
