Cecil County Public Safety Scanner — Web Audio Streaming Project

About the Project

VSS Business Solutions built this project to make audio from a Uniden SDS200 digital scanner available remotely through a standard web browser. The project combines radio hardware, local networking, streaming technology, a Windows-based service, secure web delivery, and a browser audio interface into one end-to-end system.

The original implementation used ProScan to provide the streaming layer and its Listen Live web component. That worked well, but it also meant the public listening experience depended on a third-party application that included its own management and login functions. The current design replaces that public streaming dependency with a purpose-built VSS service that communicates directly with the SDS200’s native network audio interface.

What VSS Integrated

Why the Redesign Matters

The scanner itself remains isolated on the private network. Internet listeners connect only to the VSS web service, not to the radio or a scanner-management interface. The streaming service maintains a single connection to the SDS200 and fans the audio out to website listeners, so adding listeners does not create additional sessions on the radio.

Technical Approach

The SDS200 provides the received radio audio over its network interface. The VSS Scanner Streamer runs continuously as a Windows service on the web server, receives that audio, and distributes it to browser listeners. IIS provides the public HTTPS/WebSocket endpoint while the scanner and the streamer’s diagnostic interface remain private.

The result is a small, purpose-built streaming path with no ProScan dependency in the public audio chain. It also provides a foundation for future read-only scanner status information and other monitoring features without exposing scanner control to website visitors.

A Practical Systems-Integration Example

This project is a useful example of how VSS approaches specialized requirements. The visible webpage is only the final interface; the solution depends on radio hardware, network protocols, Windows services, web-server configuration, secure Internet delivery, browser audio, monitoring, and recovery behavior working together as one system.

The same systems-integration approach applies to remote monitoring, communications equipment, IoT devices, industrial technology, environmental sensors, custom dashboards, and other requirements that do not fit neatly into a single off-the-shelf product.

Project note: This is an independent VSS Business Solutions technical project serving listeners interested in Cecil County-area radio traffic. It is not an official Cecil County government, law-enforcement, fire, EMS, or public-safety communications service, and VSS is not affiliated with the agencies whose publicly receivable radio traffic may be monitored.
