SmartAVI SDVN-4D-P 4-Port Dual-Head Secure Pro KVM Review

SmartAVI SDVN-4D-P 4 port dual head secure pro KVM DVI-I CAC smart card four computer classified

The SDVN-4D-P brings the switched CAC/PIV reader port to the 4-system dual-head DVI-I line, giving a two-monitor analyst covering four classified networks a single smart-card path that always matches whichever network is currently selected.

CAC at 4-System Dual-Head Scale

Every one of the four networks gets its own switched path to the CAC reader, so authentication never lags behind or crosses over when the operator changes which network is active on the two monitors.

Same Trusted DVI-I Dual-Head Design

Video switching behavior matches the base SDVN-4D exactly, so facilities already running SDVN-4D units can add CAC-equipped seats without retraining staff on a different switching model.

Comparison to Alternatives

Against the Avocent SCKM145, which bundles CAC with single-head VGA/DVI video, the SDVN-4D-P is the pick when two independent DVI-I monitors need to switch together with CAC. For quad-monitor CAC desks, step up to the SDVN-4Q-P.

Our verdict

Expert rating7.9 / 10

A strong 4-system, dual-monitor DVI-I choice whenever CAC/PIV authentication must travel with the video switch.

Best for

  • 4-system dual-monitor desks requiring switched CAC/PIV
  • Facilities standardizing CAC-equipped dual-head seats on DVI-I
  • Analysts consolidating a CAC reader into their existing SDVN-4D fleet

Not for

  • Sites with no CAC requirement (base SDVN-4D is cheaper)
  • Four-monitor desks (see the SDVN-4Q-P)
  • DisplayPort-native environments (see SDPN-4D-P)
