Broadcast Site Remote Monitoring: Project Overview

Broadcast Site Remote Monitoring is the practice of tracking power, environmental conditions, and critical equipment status at broadcast and communication sites—remotely and in real time—so teams can detect issues early, reduce downtime, and minimize unnecessary on-site visits. Since 2014, MRA-RAYCOM has been building a robust monitoring system to improve the reliability and uptime of their communication sites across the western United States. To ensure uninterrupted operation, the company implemented Teracom TCW122B-CM units as a core part of their monitoring and remote-control strategy. Their goal was clear: gain early visibility into power and temperature conditions and remotely control essential equipment—reducing risk, downtime, and unnecessary site visits.

What MRA-RAYCOM Monitors: Key Parameters

MRA-RAYCOM uses the TCW122B-CM devices to continuously track key infrastructure conditions at their communication facilities. The monitored parameters include:

  • Presence or absence of commercial power, using TSV100 as a detector
  • DC power supply status, connected via analog Input 1 of the controller
  • 12 VDC and battery condition, connected via analog Input 2 of the controller
  • Indoor and outdoor temperature, using TST100 as a sensor

These monitored values provide real-time insight into the site’s health and allow the team to quickly detect abnormal power conditions or environmental risks. This is a key advantage of Broadcast Site Remote Monitoring, especially for distributed sites across large geographic areas.

Remote Control Capabilities and Relay Functionality

In addition to monitoring, MRA-RAYCOM relies on the TCW122B-CM relay functionality to remotely control critical equipment, including:

  • Generators
  • Fans
  • Battery chargers
  • Air conditioning systems

This gives them the ability to respond immediately when a site’s conditions change—without waiting for technicians to arrive onsite.

Why the SNMP Monitoring System Matters

The main purpose of the system is to deliver early warnings and fast response during critical events such as:

  • Commercial power loss
  • 12 VDC power issues
  • Battery or DC supply problems
  • Overheating or shelter temperature risks

With remote access and control, MRA-RAYCOM can stabilize conditions quickly and maintain continuous operation of their communications infrastructure. This proactive approach is exactly what Broadcast Site Remote Monitoring is designed to achieve.

Integration with Nagios Core (SNMP Monitoring)

To visualize and manage the collected site data, MRA-RAYCOM integrates the TCW122B-CM devices into Nagios Core, which they use to monitor and display information about their radio sites and IP network.
To collect monitoring data efficiently across geographically distributed locations, MRA-RAYCOM uses SNMP (Simple Network Management Protocol). This allows reliable polling and centralized visibility of key power and environmental parameters from each site.

Scalability: 63+ Devices in Active Operation

Over time, MRA-RAYCOM expanded their deployment to more than 63 TCW122B-CM devices currently in operation, demonstrating both the scalability and long-term practicality of the solution across multiple states and facilities.

Results and Customer Feedback

MRA-RAYCOM reports extremely strong operational results:

  • Zero device failures since deployment
  • High confidence in device durability and stability
  • Fast and highly satisfactory support experience with Teracom

In the customer’s words, they have “never had a failure” and communication with Teracom has been “fast and to our great satisfaction.”

Conclusion

With the TCW122B-CM at the center of their monitoring system, MRA-RAYCOM has built a reliable and scalable solution that delivers early warnings for power and temperature events while enabling remote control of essential site equipment. The result is improved uptime, reduced operational risk, and stronger control over geographically distributed communications sites.
