NMX-ENC-N2312-C Encoder Card

N2300 Series 4K UHD Video over IP Card Encoder with KVM, PoE

Larger Images

The NMX-ENC-N2312 Encoder and NMX-DEC-N2322 Decoder provide a flexible, feature-rich, and simple-to-deploy Digital Media Distribution and Switching solution that can be used in 4K applications with resolutions up to 4096x2160, with support for HDCP 2.2. This motion-based wavelet codec solution delivers video with nearly imperceptible latency at an incredibly low 200 Mb/s bandwidth allowing 4K distribution over standard gigabit Ethernet networks.

Any source can be sent to one or more displays by routing through layer-2 / layer-3 switches utilizing standard Cat5e cable. The NMX-ENC-N2312 includes standard features like input scaling, bi-directional serial, IR, embedded 7.1 audio, and KVMover- IP extension. It also comes in a card version compatible with SVSI's N9206 card cage for high-density applications.
