Part 2: The Tech Behind the Screens - What IT Teams Need to Know
Introduction:
What Happens Behind the Scenes When Enterprise Digital Signage Grows
In Part 1 of this series, my colleague Noal Ronken explored the content strategy and management considerations for scaling digital signage networks. Now, we’ll examine the critical enterprise infrastructure that makes large-scale deployments possible and sustainable.
As organizations expand from a handful of screens to hundreds (or thousands) across multiple locations, the technical complexities grow exponentially. Network architecture, hardware selection, connectivity solutions, and device management all require careful planning to create a system that’s both reliable and manageable.
Through my work with enterprise clients implementing large-scale digital signage networks, I’ve identified key technical considerations that can make the difference between a successful deployment and a maintenance nightmare. This article will guide you through these considerations, and provide practical strategies for building a robust technical foundation for your digital signage ecosystem.
Network Infrastructure: Building for Scale and Security
The Critical Elements of Network Planning
When scaling your digital signage network, two infrastructure considerations become especially critical: network structure and traffic management.
Network Structure + Segmentation
As your network grows, proper segmentation becomes essential for both security and performance.
Consider organizing displays into VLANs or subnets based on location, function, or update frequency to contain traffic and enhance security. This segmentation helps isolate signage traffic from critical business systems, and creates logical grouping that simplify management.
For large digital signage deployments, the best segmentation approaches include:
- Geographic Segmentation | Group devices by physical location. (building, floor, region)
- Functional Segmentation | Separate devices by purpose. (wayfinding, employee comms, customer-facing)
- Security-Based Segmentation | Isolate devices based on content sensitivity and access requirements.
A nationwide retail chain implemented a segmentation strategy that created separate VLANs for back-office displays showing confidential sales data, and customer-facing displays in stores. This not only enhanced security but also allowed for differentiated bandwidth allocation.
Traffic Management
Digital signage can generate significant network traffic, especially when delivering video content to multiple endpoints simultaneously.
Implementing traffic prioritization ensures critical signage content isn’t delayed by competing traffic. This becomes increasingly important when screens display time-sensitive information like emergency notifications or real-time data.
Content Delivery Optimization: Pushing HD/4K video or dynamic content to thousands of screens can saturate a network. Consider content distribution strategies that minimize network impact:
- Scheduled content updates during off-peak hours.
- Delta/incremental updates that only send changed content.
- Local content caching on media players.
- Content distribution networks (CDNs) for geographically dispersed locations.
Bandwidth Considerations for Different Content Types
Not all digital signage content is created equal when it comes to network impact. IT teams must evaluate bandwidth requirements based on:
Content Types and Their Network Demands:
Low bandwidth requirements, minimal network impact
Moderate bandwidth, especially if cached locally
High bandwidth, potential for network congestion during updates
Variable bandwidth with frequent small updates
Bidirectional traffic that may require consistent connectivity
Update Frequency Factors:
Dashboards with real-time data updates, ordering/wayfinding kiosks, and digital menus might have elements that need to update at a shorter frequency than other types of content. The bandwidth for this can increase dramatically when a handful of devices are pulling data updates every few minutes vs. a few hundred devices connecting to internal or external services for this information.
Security Protocols for Distributed Networks
As your digital signage network scales across multiple locations, security becomes increasingly complex. Essential security protocols include:
- HTTPS/TLS Encryption (TLS 1.2 or higher) for all communications between players, CMS, and cloud services
- End-to-end encryption for data in transit
- Firewall implementation to protect media players
- NAT (Network Address Translation) to prevent direct exposure to the internet
- Whitelisting of CMS provider servers for cloud-based solutions
- Disable unused ports and services (USB, SSH, Bluetooth, WiFi)
- Implement hardened, read-only, or locked-down firmware
- Permit only approved applications to run on players (whitelisting)
Hardware Selection:
Choosing Media Players Build for Enterprise
Selection Criteria for Enterprise-Grade Media Players
When deploying at scale, the media player selection process becomes crucial for long-term success. IT teams should evaluate hardware based on:
- Can unused ports and services be disabled?
- Does the device use hardened, read-only, or locked-down firmware?
- Can you implement application whitelisting?
- Are all updates cryptographically signed?
- Can devices receive OTA (over-the-air) updates securely?
- Is there a regular patching schedule?
- Does the hardware support remote management?
- Can you monitor device health and status?
- Is bulk configuration possible?
Hardware Compatibility Challenges at Scale
Today’s media player landscape offers a wide range of options—from compact, low-cost units to commercial-grade displays with built-in System-on-Chip (SoC) technology. Equally diverse are the operating systems available for deployment, with Windows, Linux, Android, Samsung Tizen, and LG webOS among the most commonly used.
While this variety provides flexibility, it introduces significant challenges at scale:
Managing a fleet of devices spanning different models, manufacturers, or operating systems complicates tasks like updating apps, applying firmware patches, or performing remote management.
Different hardware platforms often require unique tools, update processes, or support strategies, making consistency and efficiency harder to maintain as the network grows.
IT teams must develop expertise across multiple platforms, increasing training requirements and potential for errors.
Various hardware platforms may have different end-of-life schedules, complicating refresh planning.
Standardizing on a single hardware platform when possible - or limit variety to a small set of carefully selected options that meet your specific deployment needs. This standardization dramatically simplifies management at scale.
Device Management: Controlling a Distributed Network
Remote Management Capabilities for Large-Scale Deployments
Going from supporting a few media players to a few hundred can go from a simple task to a daunting one without a method to easily remotely manage media players at scale. The right remote management platform becomes essential as your network grows.
Key Capabilities for Enterprise Device Management:
Manage all devices from a single dashboard.
Apply configurations, updates, and commands to groups of devices simultaneously.
Assign management rights based on roles, locations, or device groups.
Track device status, connectivity, and performance.
Generate compliance reports and status updates.
Skykit’s Advance Device Management technology simplifies large-scale deployments through several key features:
Simplify common settings like WiFi network, display orientation, time zone, and security parameters.
Assign custom labels or "tags" to media players for organizing displays into management groups.
Send commands like reboot, take screenshots, or update apps to multiple devices simultaneously.
Schedule reboots, set time zones, and define offline thresholds for groups of devices.
Essential Monitoring Capabilities
As your network scales to hundreds or thousands of endpoints, comprehensive monitoring becomes critical for maintaining uptime and performance:
- Real-time device status tracking
- Anomaly detection (bandwidth spikes, offline status)
- Device logging and retention capabilities
- Automated alerts for offline devices
- Predictive maintenance based on performance metrics
- Network redundancy and failover capabilities
Connectivity Solutions: Ensuring Reliable Content Delivery
Addressing Diverse Deployment Environments
Large-scale deployments inevitably include locations with varying network conditions, from corporate headquarters with robust infrastructure to remote locations with limited connectivity.
While a hardwired LAN connection is often the most reliable option for deploying media players, it’s not always practical. Especially in remote locations where running Cat5/6 cabling isn’t feasible, or where Wi-Fi connectivity is weak.
Strategies for Challenging Environments:
- Deploy WiFi extenders to improve signal strength in problematic areas.
- Utilize mobile-ready devices that operate independently of a company’s existing network.
- Implement local content caching to reduce network dependency.
- Consider 4G/5G connectivity options for truly remote locations.
Failover Strategies for Network Resilience
Uninterrupted content delivery, even during network issues, becomes increasingly important as digital signage moves from nice-to-have to mission-critical status.
Effective Failover Approaches:
Ensure media players store content locally so playback continues during network outages.
Deploy devices that can switch between wired, WiFi, and cellular connections.
Configure systems to automatically revert to cached or fallback content when primary content is unavailable.
Designate essential content that must continue to display even during connectivity issues.
Skykit media players cache content locally so playback continues even if the network drops. Our content distribution mechanism only updates content that's changed - saving time and bandwidth. Additionally, Skykit media players will automatically revert to cached or fallback content if content isn't available.
