Frequently Asked Questions About Secure KVM Switches
What is a secure 4-port KVM switch and why do I need one?
A secure 4-port KVM switch like the IPGARD SA-DVN-4D-P allows you to control multiple computers from a single keyboard, video, and mouse setup while maintaining complete electrical isolation between systems. This is essential in high-security environments where data separation and computer interface isolation prevent unauthorized cross-contamination between networks at different classification levels.
Does this dual-video KVM switch support 4K resolution?
Yes. The SA-DVN-4D-P supports native DVI-I resolutions up to 2560x1600 @ 60Hz and can also handle 4K Ultra-HD at 3840x2160 @ 30Hz, making it suitable for both standard and high-resolution security monitoring applications.
What does CAC support mean on a secure KVM?
CAC (Common Access Card) support means the secure KVM switch has an integrated smart card reader for multi-factor authentication. This allows users to authenticate using their government or enterprise smart card before accessing connected computers, adding an additional security layer for classified or sensitive environments.
Can I use this secure KVM with Mac and Linux computers?
Absolutely. The IPGARD SA-DVN-4D-P is fully compatible with Windows, Mac, and Linux operating systems, making it ideal for heterogeneous security environments that require multi-platform support without compromising isolation or security posture.
