Description
The CK4-HPD404C is a high-security 4-port KVM switch engineered for mission-critical environments that require strict data isolation and multi-display control. Designed for quad-head operation, this secure KVM supports DisplayPort, HDMI, and DVI interfaces simultaneously, allowing operators to manage multiple systems across four monitors from a single workstation.
Built to meet stringent security standards, this solution features CAC (Common Access Card) support for secure authentication, along with advanced USB emulation to prevent data leakage between connected systems. The unit ensures seamless switching with front panel controls while maintaining signal integrity and consistent video performance up to 4K resolution.
Ideal for government, defense, financial, and other regulated environments, the CK4-HPD404C delivers reliable, secure, and efficient multi-system control without compromising performance or compliance.
