Any alert system connected to your screens.
Integrate alerts from campus safety platforms, mass notification systems, building management software, and any custom provider. If it can send a webhook or API call, it can trigger your signage.
Connect any alert source to your signage
Not every alert comes from a federal system or standardized feed. The Third-Party Alerts integration provides a flexible framework for connecting any notification source to your digital signage network. Whether it is a campus safety platform like Rave Mobile Safety, a building management system, or a custom internal tool, Hangar.Media can receive triggers via webhooks, REST API calls, or email parsing.
What you can do with connected to your screens.
Three capabilities that make this integration essential for your digital signage network.
Trigger alerts from any system
Hangar.Media provides a unique webhook endpoint for each alert source you set up. When your campus safety system, BMS, or custom application sends a POST request to that endpoint, the alert data is parsed and displayed on targeted screens within seconds.
Our campus safety platform sends a webhook and every building screen shows the alert instantly.
Unique webhook URL per alert source for security
JSON and form-encoded payload support
HMAC signature verification for authenticated triggers
Translate any data format to screen alerts
Every alert system sends data in a different format. The field mapping engine lets you define how incoming fields map to alert title, message body, severity level, affected zones, and display duration. No code changes needed on the source system.
We mapped our BMS alarm fields to screen alerts in about ten minutes without touching the BMS config.

Default values for optional fields
Conditional mapping rules based on field content
Manage competing alert sources
When multiple alert systems are connected, conflicting alerts can arrive simultaneously. The priority engine assigns each source a priority tier so higher-priority systems always take precedence. Lower-priority alerts queue until the screen is available.
Fire alarms always override maintenance notifications, automatically, with no manual intervention.
Priority tiers for each connected alert source
Automatic conflict resolution when alerts overlap
Queue management for lower-priority alerts
Four steps to connected screens.
From setup to live content in minutes, not days.
Register an alert source
Create a new alert source in the Hangar.Media dashboard. You receive a unique webhook URL and API credentials for that source.
Set up field mapping
Define how the incoming data payload maps to alert fields. Use the visual editor to map title, message, severity, and zone targeting.
Set priority and targeting
Assign a priority tier to the source and define which screen groups should receive alerts from this system.
Send a test alert
Trigger a test alert from your source system to verify the data mapping, screen targeting, and visual presentation are correct.
Built for every sector.
See how different industries use this integration to drive results.
Campus safety platform integration
Universities connect platforms like Rave Mobile Safety or Omnilert to push campus emergency notifications to every hallway, classroom, and library screen across multiple buildings.
CorporateBuilding management system alerts
Commercial buildings connect BMS fire and HVAC alerts to digital signage so occupants see real-time notifications about building conditions alongside standard evacuation instructions.
HealthcareNurse call and code alert displays
Hospitals connect nurse call systems and code alert platforms to corridor screens so staff can see active codes and urgent patient alerts on any display in their department.
EntertainmentVenue crowd safety notifications
Large venues connect crowd management and safety systems to concourse screens to display gate closure notices, crowd flow redirections, and emergency evacuation instructions.
Common questions. Straight answers.
What alert systems can I connect
Any system that can send an HTTP webhook, REST API call, email, or MQTT message can be connected. Common sources include Rave Mobile Safety, Alertus, Omnilert, Singlewire InformaCast, building management systems, and custom internal tools.
Can I connect more than one alert system
Yes. There is no limit on the number of alert sources. Each source gets its own webhook endpoint, field mapping, priority tier, and screen targeting rules. All sources operate independently.
What if two alerts arrive at the same time
The priority engine resolves conflicts by displaying the higher-priority alert first. If both are the same priority, the most recent alert takes precedence. Lower-priority alerts queue and display once the higher-priority alert is cleared.
Do I need to modify my existing alert system
In most cases, no. If your system supports outbound webhooks or HTTP notifications, you simply point it at the Hangar.Media endpoint. The field mapping handles data format translation on the Hangar.Media side.
