Analog Technology in Schools, Commercial and Government Markets
Campus safety and education reports show that thousands of U.S. schools still use traditional analog public address (PA) and intercom systems. This aligns with the fact that the U.S. has ~130,000 K–12 schools, many built before Internet Protocol (IP)‑based systems were common.
Analog PA and intercom systems are also standard in commercial and industrial environments, including offices, hospitals, factories, hotels, retail stores, airports, and government buildings. Even a modest share of the millions of commercial buildings across the country still using analog technology represents a significant installed base.
Federal Policy is Shifting to IP
A recent Federal Communications Commission (FCC) whitepaper outlines efforts to modernize networks by reforming regulations that have slowed the transition to all-IP systems. This policy shift applies to public address and intercom systems, encouraging a move toward IP-based safety infrastructure.
In short, federal policy is moving the entire communications ecosystem toward IP – your safety systems should not be the last analog holdout.
The Hidden Costs of Staying Analog
Analog hardware is increasingly difficult to source and in many cases, no longer available. Broader technology trends, such as Microsoft ending support for Internet Explorer in 2029, signal that analog-dependent systems are entering end-of-life.
Legacy systems have significant limitations:
- No Remote Management – On-site, manual adjustments and updates are required and proactive system health monitoring is unavailable.
- Limited Integration – Access control, video management, mass notification and other security platform integrations are limited or in some cases, not an option.
- Slow or Manual Alerting – Automated alerts, pre-recorded announcements, simultaneous audio and video alerting, text-to-speech, and zone control are limited, resulting in unreliable, slow daily and emergency communication.
The AI Journal, a leading publication covering modern technology and innovation, notes in its article How Modern IP Audio Systems are Revolutionizing Public Address:
“For decades, public address systems relied on analog technology. These systems required extensive dedicated wiring, delivered inconsistent sound quality over distance, and were difficult to expand. The shift to modern IP-based audio systems is changing this by transmitting audio digitally over standard networks – improving both sound quality and operational efficiency.”
Ethernet-Based Systems – A New Standard
Ethernet-based architectures integrate with existing networks, simplify installation and reduce costs. Serverless design allows devices to connect directly to Power over Ethernet (PoE), providing benefits including:
- Seamless deployment over existing networks
- Easy scaling across buildings and campuses with minimal effort
- Support for richer audio, text, and visual alerts for accessibility compliance
- Centralized management from virtually anywhere
- Intuitive, visual command center
- Mobile duress integration without third-party infrastructure
- Integration with access control, video, and mass notification systems
- No recurring licensing fees
For example, Mount Adams School District #209 in White Swan, Washington upgraded a 25-year-old failing PA system to Telecor eSeries, gaining fully supervised endpoints and compliance with Alyssa’s Law by enabling mobile duress integration.
