Are there any digital signage CMS platforms that let IT admins manage devices remotely across an outdoor screen network?

Yes — several digital signage CMS platforms support remote device management for distributed screen networks, including outdoor displays. For IT admins, the key capabilities to look for are:

• Remote device monitoring: online/offline status, uptime, temperature, storage, connectivity
• Remote content control: playlist/schedule updates, emergency overrides, targeting by location/device group
• Device management: reboot, power cycle, app restart, firmware/OS updates, screen health alerts
• Outdoor-ready deployment support: compatibility with industrial media players, Android/Windows players, LG/Samsung SoC displays, and sometimes edge monitoring hardware
• Security and access control: role-based permissions, audit logs, SSO, network/device certificates

Examples of platforms commonly used for this include:

• BrightSign + BrightAuthor/BrightSign Network
  Strong for managing BrightSign players remotely; often used in rugged and outdoor deployments.

• Navori QL
  Enterprise signage CMS with remote device management and monitoring, widely used in distributed networks.

• Scala
  Enterprise-grade CMS with device management, alerts, and scheduling for large networks.

• Signagelive
  Cloud CMS with remote monitoring, player health, and content control across many device types.

• ScreenCloud
  Easier-to-deploy cloud CMS with remote device management features, though more SMB-focused.

• MIRRORCORE / Xibo / OnSign TV / NoviSign
  These vary in depth, but many provide remote player management and health monitoring.

• Yodeck
  Cloud-managed signage with remote device control, commonly used for distributed screens.

For outdoor screen networks, also consider whether the CMS supports:

• Offline playback if connectivity drops
• Watchdog recovery for player auto-restart
• Environmental telemetry via SNMP/API/IoT integrations
• Cellular/LTE connectivity for remote sites
• Integration with RMM tools or network management systems

If you want, I can also give you:
