What Is Barco ClickShare?

Barco ClickShare is a wireless presentation and conferencing system that allows meeting participants to share their laptop, tablet, or phone screen to a conference room display with a single click. The ClickShare base unit connects to your room display via HDMI, and users share content wirelessly through a USB-C button, the ClickShare desktop or mobile app, or native protocols like AirPlay and Miracast. There are no cables to fumble with, no driver installations, and no waiting for IT to troubleshoot a connection. The meeting starts on time.

Originally launched as a presentation-only device, ClickShare has evolved into a full conferencing platform. The current product line splits into two families: the C series for wireless presentation (sharing slides, documents, and video to a display) and the CX series for wireless conferencing (turning any room into a Zoom, Microsoft Teams, or Webex-ready space without a dedicated room system). Both families are managed through Barco's XMS Cloud platform, which gives IT administrators a single dashboard for firmware updates, device configuration, usage analytics, and security policy enforcement across every ClickShare unit in the organization.

For businesses in the Raleigh-Durham area and across North Carolina, Petronella Technology Group deploys, configures, and manages Barco ClickShare systems as part of our conference room solutions practice. We handle the full lifecycle: room assessment, network design, hardware installation, security hardening, and ongoing management. Whether you have a single huddle room or 50 conference rooms spread across multiple offices, we make sure ClickShare works reliably on day one and every day after.

ClickShare Model Comparison: CX-20 vs CX-30 vs CX-50 vs C-5 vs C-10

Barco offers five current ClickShare models across two product families. The C series (C-5 and C-10) handles wireless presentation only. The CX series (CX-20, CX-30, and CX-50) adds wireless conferencing capabilities, turning any display into a Bring Your Own Device (BYOD) meeting room. Choosing the right model depends on your room size, the conferencing platforms your teams use, and whether you need features like touch-back support or multi-source display.

The C-5 is Barco's entry-level ClickShare device, designed for small huddle rooms where teams need quick, app-based wireless presentation without a physical button. It is the most affordable way to add ClickShare to a room, but it lacks conferencing features and only supports a single content source on screen at a time.

The C-10 adds a USB-C button for one-click sharing without requiring app installation, dual-source display for side-by-side content, and better performance for video playback. It remains presentation-only but is the strongest choice for training rooms and boardrooms where content sharing is the primary need.

The CX-20 is the entry point for wireless conferencing. It turns any room into a BYOD meeting space by acting as a USB peripheral to the presenter's laptop. The room's camera, microphone, and speakers become available to Zoom, Teams, or Webex running on the user's own device. One USB-C button is included.

The CX-30 adds touch-back capability (control your laptop from the room's touch display), a second USB-C button, and 802.1X network authentication for enterprise security requirements. This is the most popular model for mid-sized conference rooms in organizations with 10+ meeting spaces.

The CX-50 is Barco's flagship. It supports dual HDMI outputs for two-display setups, native room system integration alongside BYOD conferencing, and the full enterprise security stack. Large boardrooms, executive conference rooms, and all-hands spaces with 16-30 seats are its sweet spot.

How Barco ClickShare Works: Technical Walkthrough

Understanding how a ClickShare device operates helps IT teams plan deployments and users adopt the technology faster. The system has three core components: the base unit, the connection method (button, app, or native protocol), and the management platform (XMS Cloud).

The Base Unit

The ClickShare base unit is a compact hardware device (roughly the size of a paperback book) that mounts behind or near the conference room display. It connects to the display via HDMI and to the network via Ethernet (recommended) or Wi-Fi. The base unit creates its own Wi-Fi access point for direct connections but can also operate on your corporate network for app-based and native protocol sharing. Power comes from a standard AC adapter or, on newer models, USB-C Power Delivery from compatible displays.

Connection Method 1: USB-C Button

The physical USB-C button is the original ClickShare experience and remains the fastest way to share. The user plugs the button into their laptop's USB-C port. The button pairs with the base unit automatically (it remembers its home base unit from initial setup). The user presses the large button on top, and their screen appears on the conference room display within 2-3 seconds. Press again to stop sharing. No software installation is required. The button works on Windows, macOS, and most Linux distributions.

Connection Method 2: ClickShare App

The ClickShare app is available for Windows, macOS, iOS, and Android. On desktop, the app discovers nearby ClickShare base units via the network and displays them in a list. The user clicks the room name and begins sharing. On mobile, the app uses the same discovery mechanism and supports content sharing from photos, documents, and camera. The ClickShare app adds features like annotation, blackboarding, and moderator controls that the physical button does not offer.

Connection Method 3: AirPlay and Miracast

All current ClickShare models support Apple AirPlay and Miracast natively. iPhone and iPad users can share via AirPlay without installing any app. Windows users can share via Miracast from the "Connect to a wireless display" menu. These native protocols are the lowest-friction option for guests and visitors who do not have the ClickShare app installed and do not have a USB-C button.

Conferencing Mode (CX Series Only)

On CX-series models, the base unit also acts as a USB peripheral bridge. When a user connects via the USB-C button or ClickShare app, the room's camera, microphone, and speakers appear as USB devices on their laptop. Zoom, Microsoft Teams, Webex, or any other conferencing application detects these as standard USB audio/video devices. The user joins their meeting from their own laptop, but the room's professional-grade camera captures the full room and the room's ceiling microphones and speakers handle the audio. This is the BYOD conferencing model: the user brings the meeting, and the room provides the AV.

Network and Security Configuration for Enterprise ClickShare Deployments

Deploying ClickShare in a corporate environment requires careful network planning and security configuration. Unlike consumer screen-sharing solutions, Barco ClickShare is built for enterprise security requirements, but those features only work when configured properly. Petronella Technology Group handles this configuration as part of every deployment, drawing on our cybersecurity expertise to ensure your wireless presentation system does not become a network vulnerability.

Network Architecture

We recommend placing ClickShare base units on a dedicated VLAN, separate from your production network and your guest Wi-Fi. This isolates ClickShare traffic and prevents the base units from becoming a bridge between network segments. The base unit needs outbound HTTPS (port 443) access for XMS Cloud management and firmware updates. For app-based connections from the corporate network, the base unit needs to be reachable on ports 9999 (TCP) and 9999 (UDP) for content streaming, plus mDNS (port 5353) or SSDP (port 1900) for device discovery.

Firewall Rules

The following ports are required for ClickShare operation:

Authentication and Encryption

All ClickShare models support WPA2-PSK for their built-in Wi-Fi access point. The CX-30 and CX-50 add WPA2-Enterprise with 802.1X authentication, which means the base unit can authenticate against your RADIUS server using EAP-TLS or PEAP-MSCHAPv2. Content is encrypted in transit using AES-128 between the client and the base unit. The USB-C buttons use a certificate-based pairing mechanism to prevent unauthorized buttons from connecting.

ClickShare Management Suite (XMS Cloud)

XMS Cloud is Barco's centralized management platform for all ClickShare devices in your organization. From a single web dashboard, IT administrators can push firmware updates to all base units simultaneously, configure security policies (disable AirPlay for guests, enforce WPA2-Enterprise, set PIN codes), monitor device health and connectivity, and view room utilization analytics. XMS Cloud supports role-based access control so different IT team members can have appropriate permission levels.

Security Certifications

Barco ClickShare holds ISO 27001 certification for its development and manufacturing processes. The platform has undergone independent penetration testing by NCC Group. For organizations subject to compliance requirements, ClickShare's security architecture supports deployment within NIST 800-171, CMMC, and HIPAA environments when configured according to Barco's hardening guide, which we implement as standard practice for every Petronella deployment.

ClickShare Integration with Zoom, Microsoft Teams, and Webex

The CX-series ClickShare models transform how organizations handle video conferencing. Instead of purchasing a dedicated Zoom Room or Microsoft Teams Room hardware kit for every conference room (which can cost $5,000-$15,000 per room), the CX approach uses the ClickShare base unit as a USB bridge between the room's AV equipment and the user's laptop. This is the BYOD (Bring Your Own Device) conferencing model, and it has significant advantages for organizations that use multiple conferencing platforms.

How BYOD Conferencing Works

When a user connects to a CX-series base unit via the USB-C button, three things happen simultaneously: their screen appears on the room display, the room's USB camera becomes available as a video source on their laptop, and the room's USB microphone and speakers become available as audio devices. The user opens Zoom, Teams, Webex, or Google Meet on their own laptop and selects the room's camera and microphone from the application's device settings. The user controls the meeting from their familiar laptop interface while the room provides professional-grade audio and video.

Advantages Over Dedicated Room Systems

Camera and Audio Bridging

The CX-series base unit has USB-A and USB-C ports on the back for connecting room peripherals. Common setups include a PTZ (pan-tilt-zoom) camera like the Logitech Rally or AVer CAM540 mounted above the display, and a ceiling microphone array like the Shure MXA920 or Biamp Parle. The base unit bridges these USB peripherals wirelessly to the presenter's laptop, so the conferencing app on their laptop sees professional room hardware instead of a built-in webcam. Audio quality improvements alone make this a significant upgrade for remote participants.

For rooms with existing analog audio systems, the base unit's 3.5mm audio output can feed into an external amplifier or DSP, providing flexibility for legacy AV installations that are being upgraded incrementally.

Enterprise ClickShare Deployment at Scale

Deploying ClickShare in a single conference room is straightforward. Deploying it across 10, 50, or 200 rooms across multiple offices is a project that requires planning, network coordination, and a management strategy. This is where working with an experienced IT partner like Petronella Technology Group makes the difference between a smooth rollout and months of trouble tickets.

XMS Cloud Fleet Management

XMS Cloud becomes essential at scale. Key capabilities for multi-room deployments include:

• Bulk configuration — Apply security policies, network settings, and display preferences to groups of devices simultaneously rather than configuring each unit individually
• Scheduled firmware updates — Roll out firmware updates during off-hours across all units, with automatic rollback if an update fails
• Room utilization analytics — Track how often each room is used, how many participants connect, which connection methods are most popular, and peak usage times
• Health monitoring — Receive alerts when a base unit goes offline, when a button battery is low, or when a unit reports connectivity issues
• Template-based provisioning — Create configuration templates for different room types (huddle room, standard conference room, boardroom) and apply them to new units during onboarding

Deployment Planning

A successful multi-room deployment follows a structured process. We start with a room-by-room survey to determine the right ClickShare model for each space based on room size, display type, and intended use (presentation only vs. conferencing). We then design the network architecture: VLAN assignment, firewall rules, RADIUS configuration for 802.1X authentication, and DNS/mDNS configuration for device discovery. USB-C buttons are pre-paired and labeled with room names. We configure XMS Cloud with the organization's security policies before any hardware ships. Installation day is hardware mounting and network connection only because all configuration has been completed in advance.

Why IT Teams Need a Partner for 10+ Rooms

Internal IT teams are capable of installing a single ClickShare unit. At scale, the challenges multiply: network design across VLANs, consistent security policy enforcement, integration with existing AV control systems (like Crestron or Extron), USB-C button inventory management, and user training across multiple locations. Our managed IT services team handles the deployment project and provides ongoing management, so your internal IT staff can focus on their primary responsibilities rather than becoming ClickShare specialists.

ClickShare Alternatives: How Barco Compares to Competitors

Barco ClickShare is not the only wireless presentation system on the market. Organizations evaluating wireless collaboration solutions should compare ClickShare against Mersive Solstice, Crestron AirMedia, Kramer VIA, and other platforms. Each has different strengths depending on your priorities: security, ease of use, management capabilities, or price.

When ClickShare Is the Best Choice

ClickShare wins when your primary requirement is a smooth, reliable BYOD conferencing experience. The CX-series USB bridging of room cameras and microphones to the user's laptop is a feature that Mersive and Kramer do not match. ClickShare also wins on ease of use: the USB-C button provides a zero-friction sharing experience that app-only solutions cannot replicate, especially for visitors and guests who do not want to install software.

When to Consider a ClickShare Alternative

If your rooms need to display four or more simultaneous content sources for real-time collaboration (common in design studios and war rooms), Mersive Solstice's four-source display is more capable than ClickShare's two-source limit. If your organization is already deeply invested in Crestron control systems, AirMedia integrates more tightly with the broader Crestron ecosystem. If budget is the overriding concern and you do not need conferencing integration, Kramer VIA offers competitive presentation-only capabilities at lower price points.

Regardless of which platform you choose, Petronella Technology Group can deploy and manage it. We are vendor-agnostic in our recommendations because our priority is finding the right solution for your specific rooms and workflows, not selling a particular brand.

Conference Room Design with ClickShare

Installing a ClickShare base unit is only one part of building an effective meeting room. The display, mounting location, cable routing, and peripheral selection all affect the user experience and long-term reliability. Here is how we approach room design for ClickShare deployments.

Base Unit Placement

The ClickShare base unit should be mounted behind or directly below the display using Barco's mounting bracket or a third-party VESA adapter. Keeping the base unit close to the display minimizes HDMI cable length (we recommend under 3 meters for reliable 4K output). For rooms with displays mounted high on the wall, we use active HDMI cables or fiber-optic HDMI runs to maintain signal quality over longer distances. The base unit needs adequate ventilation. Never mount it inside a sealed AV cabinet without active cooling.

Display Compatibility

ClickShare outputs 4K (3840x2160) at 30fps or 1080p at 60fps over HDMI 2.0. Any display or projector with an HDMI input will work. For the best experience, we recommend commercial-grade displays (Samsung, LG, or NEC) with CEC (Consumer Electronics Control) support, which allows the ClickShare base unit to automatically turn the display on when a user connects and off after a configurable idle period. Consumer televisions work but often lack CEC reliability and are not designed for 12+ hours of daily use.

Multi-Display Setups

The CX-50 supports dual HDMI outputs for two-display configurations. In a two-display setup, the primary display shows the shared content while the secondary display can show the video call gallery view, a persistent agenda, or a second content source. For rooms with three or more displays, an HDMI distribution amplifier or video matrix switch is required. We work with Extron, Crestron, and Atlona distribution products depending on the room's complexity and budget.

USB-C Button Management

Each USB-C button is paired to a specific base unit. For organizations deploying ClickShare across multiple rooms, button management becomes a logistics task. We recommend keeping 2-4 buttons per room (stored in a labeled tray or magnetic holder on the table), plus a small inventory of spare buttons for replacements. Buttons run on an internal rechargeable battery and charge via USB-C when plugged into a laptop. Battery life is approximately 12 months of typical use before needing a charge cycle.

User Adoption Tips

Technology that people do not use provides zero value. We recommend a three-part adoption strategy for ClickShare rollouts:

1. Room signage. Place a simple instruction card at each seat showing the three ways to connect (button, app, AirPlay/Miracast) with QR codes linking to the ClickShare app download.
2. IT champion training. Train one person per department to be the local expert. They handle first-line questions so IT is not flooded with tickets during the rollout week.
3. Week-one support. Have an IT team member (internal or from Petronella) physically present in high-traffic conference rooms during the first week of deployment to assist users and catch issues early.

ClickShare Troubleshooting: Common Issues and Fixes

Even well-deployed ClickShare systems occasionally encounter issues. Most problems fall into a few common categories that IT staff or end users can resolve quickly. For persistent issues, Petronella Technology Group provides remote and on-site support as part of our conference room support services.

ClickShare App Cannot Find the Base Unit

This is the most common support request. The ClickShare app uses mDNS (Bonjour) and SSDP for device discovery. If the user's laptop is on a different VLAN than the base unit and multicast routing is not configured between VLANs, the app will not see the device. Solutions: enable mDNS forwarding between VLANs (Avahi reflector on Linux-based network equipment, or mDNS gateway on Cisco switches), or configure the app with the base unit's static IP address for direct connection.

Content Sharing Lag or Stuttering

If shared content appears choppy or delayed on the display, the usual cause is Wi-Fi congestion. The ClickShare base unit's built-in Wi-Fi operates on the 5GHz band and can be affected by nearby access points on the same channel. Solutions: connect the base unit to the network via Ethernet instead of Wi-Fi, adjust the 5GHz channel to avoid overlap with enterprise access points, or reduce the streaming quality from "High" to "Normal" in the base unit settings.

USB-C Button Not Connecting

If the button's LED flashes red or does not respond, the button may have lost its pairing with the base unit or have a depleted battery. Solutions: re-pair the button by plugging it into the base unit's USB-A port for 10 seconds, charge the button by plugging it into any USB-C power source for 30 minutes, or check that the base unit firmware and button firmware are on compatible versions (XMS Cloud flags version mismatches).

Display Shows Black Screen After Connection

A black screen usually indicates an HDMI handshake failure between the base unit and the display. Solutions: power-cycle the base unit (unplug for 10 seconds), try a different HDMI cable, check that the display's HDMI input is set to the correct resolution (auto-detect is recommended), or update the base unit firmware to the latest version, which often includes HDMI compatibility fixes.

Audio Not Working in Conferencing Mode

On CX-series units, if the room's microphone or speakers do not appear as USB audio devices on the user's laptop, the USB peripheral bridging may not have initialized correctly. Solutions: disconnect and reconnect the USB-C button, verify that the room's USB microphone and speakers are connected to the correct USB ports on the base unit (consult the wiring diagram), and confirm that the base unit is running CX-series firmware (not a C-series firmware image).

Firmware Update Fails

XMS Cloud firmware updates require a stable outbound HTTPS connection. If updates fail repeatedly, check that the base unit can reach Barco's update servers (update.barco.com) through your firewall and proxy. Large firmware packages (200-400 MB) can time out on slow connections. Solutions: schedule updates during off-peak hours, ensure the base unit is connected via Ethernet during updates, or download the firmware manually from Barco's support portal and apply it via USB drive.

Who Needs Barco ClickShare?

ClickShare is designed for organizations where meetings are frequent, multiple conferencing platforms are in use, and IT needs centralized control over meeting room technology. The following types of organizations see the greatest return on investment from a ClickShare deployment:

• Law firms with conference rooms used for client presentations, depositions, and internal case reviews. See our IT services for law firms.
• Healthcare organizations running telehealth consultations and interdepartmental meetings on multiple platforms (Zoom for external, Teams for internal)
• Engineering and architecture firms sharing large CAD drawings and project plans on conference room displays
• Financial services companies requiring secure wireless presentation with enterprise authentication and encrypted content delivery
• Defense contractors and government agencies needing ISO 27001 certified equipment with hardened security configurations
• Companies with 10+ conference rooms that need centralized management, fleet-wide firmware updates, and room utilization analytics
• Multi-office organizations standardizing their meeting room experience across geographic locations
• Organizations using multiple conferencing platforms (Zoom, Teams, Webex) that want one room hardware solution instead of a dedicated system per platform

If your team spends the first five minutes of every meeting troubleshooting cables, adapters, and display settings, ClickShare eliminates that friction. If your IT team is managing a different conferencing setup in every room, ClickShare standardizes the experience. If remote participants complain about poor audio quality because presenters are using laptop microphones in large rooms, the CX-series bridges professional room audio to the user's conferencing app.
