Cisco CS-ROOM55-K9 Cisco Webex Room 55 All-in-One Collaboration System (Radio Enabled) Full Official English Description

1. Product Overview

Cisco CS-ROOM55-K9, officially namedCisco Webex Room 55 All-in-One Video Conferencing System (Radio Enabled), is an integrated all-in-one enterprise collaboration endpoint optimized for small-to-medium meeting rooms that seat up to seven participants. This unified unit consolidates a 55-inch 4K display, built-in media codec, HD camera, six-element embedded microphone array, and full-range stereo speaker system into a single sleek chassis, earning Red Dot industrial design recognition with aluminum and fabric construction.

The suffixK9denotes the radio-enabled variant equipped with dual-band Wi-Fi 802.11ac and Bluetooth wireless radio modules, supporting wireless screen sharing and mobile device proximity pairing. Powered by Cisco RoomOS / Cisco Collaboration Endpoint Software v8.0 and above, Room 55 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 delivers native AI camera tracking, wired/wireless presentation sharing, enterprise-grade audio DSP processing, OBTP one-touch meeting join, room occupancy analytics, and full xAPI room automation capabilities. A matching NR (No Radio) SKU (CS-ROOM55-NR-K9) exists for RF-restricted secure environments with all wireless hardware removed.
