TelemetryOS Edge

TelemetryOS Edge is a purpose-built Linux operating system that runs the TOS Player runtime securely and efficiently at enterprise scale. The system delivers 24/7 reliability through a hardened, minimal architecture optimized for application deployment, media playback, and interactive experiences.

TOS Player

TOS Player delivers native performance with hardware acceleration and wider media support, while providing deterministic caching and staged downloads for reliable offline playback. It also integrates with the OS and peripherals (for example, kiosk mode or display control) and supports versioned updates with rollback.

Technical Architecture

TelemetryOS Edge is built on a minimal, custom Linux foundation that eliminates non-essential services and packages to create an appliance-like operating environment optimized for deployed screen applications.

The architecture consists of several integrated layers. The hardened Linux base provides a minimal build with non-essential services removed to reduce the attack surface and improve reliability. The TOS Player runtime serves as the native media player with hardware acceleration and deterministic caching capabilities. A comprehensive security layer implements mandatory access controls with containerized application isolation to protect system integrity. The management interface provides cloud-integrated monitoring and configuration for remote fleet management.

TelemetryOS Edge operates as part of a complete vertical integration: Node hardware runs TelemetryOS Edge OS with the TOS Player runtime, all connected to the TelemetryOS cloud control plane. This integration ensures optimal performance and security across all system layers. The system uses a read-only root filesystem to prevent tampering, with automatic recovery orchestration that returns the device to a known-good state after power loss or failed updates.

Security and Hardening

TelemetryOS Edge implements a defense-in-depth security model designed for enterprise deployment environments. Only essential components are included in the Linux build, creating a minimal attack surface. Applications run in isolated, sandboxed containers with constrained resources and signed artifacts. Full-disk encryption protects stored data, with guarded inter-process communication between system components.

All network traffic is encrypted with TLS 1.3 and certificate pinning. WPA2-Enterprise certificate-based authentication is supported with VLAN isolation for network segmentation. Outbound connections are restricted and integrate with enterprise firewall configurations.

🔒

TelemetryOS Edge maintains SOC 2 Type II compliance with automated security patching that preserves system integrity while keeping devices current.

Performance

The system is engineered for 24/7 media playback reliability with optimizations targeting deployed screen applications. Video playback supports 4K resolution at 60Hz across up to three independent displays, with a hardware-accelerated pipeline for wide media format support. Local input handling enables responsive interactive applications and kiosks, while deterministic content caching ensures extended offline playback even during prolonged connectivity interruptions.

Content delivery includes automatic predictive caching with staged downloads, eliminating the need for bandwidth micromanagement while ensuring content is always ready before it's scheduled to play.

Deployment Models

TelemetryOS Edge supports multiple deployment patterns based on organizational scale and requirements. Device-level provisioning configures network, timezone, and screen layout settings directly on each device — best suited for small deployments or locations with unique requirements. Token-based provisioning pre-configures WiFi, timezone, display, and proxy settings before device activation, enabling consistent, zero-touch deployments at scale.

Small businesses with fewer than ten devices typically benefit from device-level provisioning for its flexibility. Enterprises with ten to one hundred devices see better results with token-based provisioning for consistency and reduced deployment time. Large fleets exceeding one hundred devices should use staged token deployment for efficient rollouts.

Fleet Management

TelemetryOS Edge integrates with the TelemetryOS cloud platform for comprehensive fleet management. Real-time monitoring provides anomaly detection with configurable alerts for proactive issue identification. System health tracking covers CPU temperature, storage capacity, and network metrics. Content verification through live screenshots enables remote troubleshooting, and geographic mapping with status indicators provides centralized fleet visibility.

Updates are delivered through controlled maintenance windows with staged rollouts to minimize disruption. Automated security patching preserves system integrity while keeping devices current. A one-click rollback system enables rapid failure resolution, and fleet-wide version control maintains configuration stability across every device.

Hardware

The recommended hardware is the Node Pro, which ships with TelemetryOS Edge pre-installed and has been tested and validated for enterprise-grade, fanless operation. Node devices support sensor integration, RS232/RS485 serial connections for legacy systems, GPIO for custom hardware interfaces, and dual HDMI 2.0 with USB-C DisplayPort for multi-screen configurations.

ℹ️

For multi-screen, video walls, and odd-sized displays, align your hardware choice with your software stack: Node Pro deployments use TelemetryOS Edge, while Android deployments use Node Mini.

🧭

Multi-screen and video wall deployments require early hardware planning for GPU and output validation. TelemetryOS support provides hardware compatibility verification for custom deployment configurations.
