Description

The Belkin Universal 2nd Gen Secure KVM Switch 4-Port Dual Head is engineered for mission-critical environments that demand uncompromising security, flexibility, and performance. Designed to meet stringent NIAP Protection Profile PSD 4.0 standards, this secure KVM solution enables seamless control of up to four computers while maintaining strict data isolation between systems.

Built for modern and legacy compatibility, this KVM switch supports DisplayPort, HDMI, and DVI-D through passive cabling, delivering up to 4K resolution at 60Hz without the need for external converters. Its advanced architecture ensures secure video channel switching and peripheral isolation, preventing data leakage across security domains.

The tamper-proof design includes an always-on, battery-backed anti-tamper system that safeguards the unit both in transit and during operation. Enhanced usability features such as configurable port identification, optional remote control integration, and ergonomic mounting options make it ideal for government, military, financial, and other high-security environments.
