Kramer KDS-100DEC Open–Standard 4K AVoIP Decoder with Ultra–Low Latency

KDS 100DEC is a professional AVoIP decoder designed to render high quality 4K video from open standard H.264/H.265 streams over standard 1GbE networks. It delivers pristine images to local HDMI displays with ~40 ms end−to−end latency (when paired with KDS 100 encoders), ideal for command rooms, monitoring walls, and operator desks.

•  Dual Streaming — Supports KDS–100 Encoder primary and/or secondary stream.
•  Predefined deployment profiles — Make system setup easy and adaptable to both high–capacity and constrained networks
•  Channel–based routing — Easily choose your source, IP addressing expertise required.
•  Auxiliary Data transmission — RS–232 control commands are delivered to/from peripheral devices, providing seamless AV and control integration.
•  Kramer AVoIP Manager integration — Enables automatic device discovery, centralized configuration, and real–time monitoring across the entire AVoIP deployment.
•  IT–grade Security — HTTPS/TLS, 802.1x, and OWASP–10 aligned practices.

Key Features
