IPGARD Secure 4-port, dual-link DVI-I KVM switch with dedicated CAC port, 4K support & preview screen.

The multiviewer allows users to control KVM (Keyboard, Video and Mouse) operation on up to four computers with DVI displays (HDMI or VGA w/ adaptor). It features mechanical, electrical and optical signal isolation to prevent hacking and data leakage in environments where security is paramount. With the multiviewer, all data relays are controlled by inverted signals, shielding connections from outside intrusion by forcing them each to work one at a time. Each port uses its own isolated data channel and each unit features non-reprogrammable ROM to better protect the switch’s functions. Better yet, the protector offers the highest security when accessing classified and public networks over the internet through these isolated connections. By isolating connections between networks, the multiviewer ensures no data is leaked between secure ports and the outside world. The multiviewer has clearly marked front-panel buttons for controlling the device, so securely switching between sources is always simple. For high-grade secure switching made easy, look no further than the multiviewer.
