Kramer 22-00000620 SX42HU-3 HighSecLabs Secure 2x4 4K30 UHD HDMI Mini-Matrix KVM Switch with fUSB

Protect sensitive workflows while enabling efficient multi-system operations with the Kramer Electronics SX42HU-3 secure 2x4 4K30 UHD HDMI mini-matrix KVM switch. Designed for high-security environments, this pro HDMI KVM switch lets a single operator view and control up to four classified computers with strong hardware isolation to prevent information leaks and peripheral exploitation. Certified to NIAP Common Criteria Protection Profile v3.0, the SX42HU-3 provides trusted isolation for monitoring, surveillance and command-and-control applications.

Operators benefit from crisp 4K30 video (3840×2160 @30Hz) across multiple displays, independent switching of keyboard, mouse, audio and USB devices, and fine-grained fUSB mapping so a smart card or biometric reader can remain permanently assigned to a specific host. Built-in USB filtering blocks unauthorized devices by VID/PID and the Virtual Display Technology enables smooth switching by moving the cursor between display borders.

Ideal for government agencies, military, financial and critical-infrastructure control rooms that require both security and usability. Contact your Kramer reseller to integrate the SX42HU-3 into your secure monitoring or surveillance deployment.
