Cisco CS-CODECPLUS-K9 Cisco Webex Codec Plus (Radio Enabled) Full Official English Description

1. Product Overview

Cisco CS-CODECPLUS-K9, officially namedCisco Webex Codec Plus Radio-Enabled Standalone Media Codec, is the core standalone video and audio processing engine of Cisco Webex Room Kit Plus enterprise video conferencing series. This K9 variant is equipped with built-in dual-band Wi-Fi and Bluetooth radio modules, supporting wireless content sharing and mobile device proximity pairing.

Designed as a modular separate codec unit, it decouples media processing hardware from camera/speaker peripherals, delivering flexible AV integration for medium-to-large corporate boardrooms, training auditoriums and multi-purpose collaboration spaces. It works natively with Cisco Quad Camera, Precision 60 PTZ camera, Touch 10 Room Navigator, and supports expansion table microphones and external audio amplifiersCisco Russ....

Powered by Cisco RoomOS / Cisco Collaboration Endpoint Software v9.0 and above, Codec Plus supports dual deployment architectures: cloud registration via Cisco Webex Control Hub, and on-premises registration with Cisco Unified Communications Manager (CUCM) and Cisco Expressway firewall traversal gateways. It integrates full AI camera orchestration, dual 4K display routing, multi-channel digital audio DSP, embedded MultiSite 4-way multipoint conferencing, and enterprise-grade network security features.
