CS-DESK-K9 Description
The CS-DESK-K9 is a Cisco Desk personal video endpoint for individual desks, where it replaces both the monitor and the webcam. The endpoint has a 24-inch 1080p touch display, an 8 MP camera with a 64-degree horizontal field of view, a four-microphone array and a 70W maximum rated power draw. One USB-C cable extends a computer’s display at 1920 x 1080 at 60 fps, and four-way embedded conferencing needs the MultiSite software option.

Key Features
A single USB-C connection extends the computer’s desktop at 1920 x 1080 at 60 fps and hands the camera, microphone and speakers back to any software client. One cable replaces the monitor lead, the webcam and the headset.
On supported operating systems the panel forwards touch input to the attached computer, so the display works as an input device and not only as a screen.
The camera has a mechanical shutter with its own LED, which shows the camera state without depending on software.
A dynamic four-microphone array provides focused pickup, AI-powered noise removal, automatic gain control and active lip synchronization, with a separate music mode.
With the MultiSite option the endpoint hosts SIP and H.323 calls itself: three-way at up to 1080p30 or four-way at up to 720p30, with full individual audio and video transcoding.
The endpoint moves to Halfwake after two minutes idle, to DisplayOff standby after ten and to networked standby after twelve, where it draws 7.5W at most.
Application Scenarios
At a personal desk, the endpoint serves as the only screen, taking the laptop’s display over one USB-C cable while its own camera and microphones handle video calls.
Staff who bring a laptop to a shared hot desk can join calls in any meeting client, because the camera, microphone array and speakers pass through the same USB-C cable.
A person who co-creates on shared content can annotate directly on the 24-inch touch panel with a finger or the optional stylus kit.
Selection Guide
CS-DESK-K9 suits a personal desk where a 24-inch 1080p touch display with an 8 MP camera replaces the monitor. Desks that need a 27-inch 4K panel and a 12 MP camera move to CS-DESKPRO-K9. Sites that prohibit wireless radios take CS-DESK-NR-K9, and US Government orders take CS-DESK-K9++. Four-way embedded conferencing is available only with the LIC-DESK-MS MultiSite option.
Ordering Checklist
- MultiSite option: Add LIC-DESK-MS if the Desk must host four-way SIP and H.323 conferences. The base part number does not include embedded multipoint.
- Default carton: The Desk Stand, 3 m network cable, 1.8 m USB-C cable and power supply already ship with CS-DESK-K9. Ordering them again duplicates parts already in the box.
- Wall or VESA mounting: Order CS-DESK-WALL= for wall mounting or CS-DESK-VESA= for a VESA adapter. Only the Desk Stand ships in the carton, so any other mounting needs its own part.
- Stylus kit: Add CS-DESK-STYLUSKIT= with 2 styluses and 4 tips. Styluses are not in the carton, so annotation without the kit is limited to finger touch.
