Cisco CS-ROOM55-NR-K9 Webex Room 55 All-in-One Collaboration System (No Radio, Encrypted) Full Official English Description

1. Product Overview

Cisco CS-ROOM55-NR-K9, officially namedCisco Webex Room 55 All-in-One Video Conferencing System – No Radio Encrypted Bundle, is a fully integrated enterprise collaboration endpoint optimized for small-to-medium meeting rooms with seating capacity up to seven participants. The suffixNR (No Radio)means all built-in dual-band Wi-Fi 802.11ac and Bluetooth radio modules are completely removed from the integrated codec hardware, eliminating all RF signal transmission, confidential meeting content interception and data leakage risks. It fully complies with strict RF-prohibited secure environments including classified government offices, military facilities, regulated financial institutions and industrial sites that ban all wireless transmission hardwareCisco.

This single-piece unified device consolidates a 55-inch professional 4K LCD display, embedded media codec, integrated HD camera, six-element beamforming microphone array and built-in multi-channel stereo speaker system into one sleek Red Dot Award-winning aluminum and fabric chassis. The complete factory bundle includes the Room 55 main unit and a Cisco Touch 10 wired touch control panel for meeting operation. Powered by Cisco Collaboration Endpoint Software v8.0 and newer, the NR variant only supports wired-only 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. All core AI camera tracking, wired presentation sharing, enterprise DSP audio processing, OBTP one-touch meeting join, room occupancy analytics and xAPI room automation functions remain fully intact. Only wireless screen sharing (AirPlay/Miracast) and wireless mobile device proximity pairing functions are permanently disabled due to hardware-level removal of radio modules.
