Building Automation Networking

The Network Backbone Your Building Systems Depend On

Smart buildings aren't smart when the network underneath them wasn't designed for building automation. HVAC controls, lighting, occupancy sensors, and energy management platforms all require reliable, properly segmented network infrastructure - and most facilities don't have it.

SRS Networks builds the IT/OT network backbone that your building automation system runs on - with the security, reliability, and protocol support it actually requires.

The Problem

Why Building Automation Networks Keep Failing

Building automation is only as reliable as the network it runs on. Most BAS failures, security incidents, and management headaches come from networks that were never designed with operational technology in mind.

Siloed Building Systems With No Unified View

HVAC controls, lighting, access control, and energy management all run on separate platforms with no integration. Facility managers are juggling multiple logins and getting no unified picture of building performance.

Legacy BAS Protocols on Modern Networks

BACnet, Modbus, and LonWorks weren't designed for IP networks. When legacy automation protocols get bridged onto corporate infrastructure without proper configuration, the result is communication failures, dropped commands, and unreliable control.

Critical Security Gaps Between IT and OT

Building systems connected to flat corporate networks create attack surface that most IT teams don't monitor. A compromise of a BAS controller is a foothold into infrastructure far more sensitive than the building's HVAC.

No Network Segmentation for Building Systems

IoT sensors, BAS controllers, and automation endpoints sitting on the same VLAN as corporate workstations is a configuration no modern security posture can defend. Flat OT networks aren't acceptable anymore.

Unreliable Connectivity for Automation Endpoints

Occupancy sensors that don't report, lighting commands that don't execute, and HVAC setpoints that don't hold - almost always traced back to wireless coverage gaps or wired infrastructure that was never designed for IoT density.

The Solution

Network Infrastructure Purpose-Built for Your Building Systems.

SRS Networks designs and deploys OT network infrastructure that gives your building automation systems the connectivity, segmentation, and protocol support they require. We understand both sides - the IT network that needs to stay secure, and the BAS environment that needs to stay operational. The result is an architecture where both can coexist without compromise on either front.

What's Included

Everything Your BAS Network Needs

From OT architecture design through security boundary implementation and ongoing monitoring, SRS Networks handles every layer of your building automation network buildout.

OT Network Architecture Design

We design a purpose-built network architecture that supports your BAS platform and protocols while keeping building automation traffic isolated from corporate IT. Every segment, VLAN, and routing policy is documented before the first cable is pulled.

OT/IT zone segmentation design
BAS VLAN architecture
Protocol gateway planning

IT/OT Security Boundary

Firewall policies, access control lists, and network segmentation enforce a hard boundary between building systems and corporate infrastructure - with controlled conduits for management traffic only.

Firewall rule design for OT/IT boundary
Access control list implementation
Remote access policy for BAS management

IoT & BAS Endpoint Connectivity

Wired and wireless infrastructure designed for the density and distribution of building automation endpoints - occupancy sensors, VAV controllers, lighting nodes, and access hardware - with reliable connectivity at every point.

PoE switch deployment for BAS endpoints
Wireless coverage for IoT sensor density
Cable infrastructure for BAS controller panels

Unified Management & Monitoring

A centralized network management platform gives your facilities and IT teams shared visibility into building system connectivity - with alerting when endpoints go offline, bandwidth anomalies, or security events occur.

Centralized NMS with BAS device inventory
Uptime alerting for critical BAS endpoints
Bandwidth monitoring per OT segment
The Difference

Flat OT Network vs. SRS Purpose-Built BAS Infrastructure

The difference between a building automation network that was designed and one that just grew shows up in reliability, security, and your team's ability to manage it.

Real-World Use Cases

Built for Every Facility That Runs on Automation

Whether you're deploying a new BAS platform or hardening the network behind an existing one, SRS Networks brings the infrastructure expertise your building systems require.

Commercial Office Buildings

Multi-floor commercial properties with HVAC zoning, smart lighting, occupancy-based controls, and energy management platforms all running on segmented, purpose-built building automation network infrastructure.

Multi-Tenant Properties

Shared building infrastructure that supports tenant-specific BAS access without exposing one tenant's systems to another. Network segmentation enforces isolation while enabling centralized facility management.

Healthcare Facilities

Hospitals and medical campuses where HVAC controls, environmental monitoring, and access control systems require the highest reliability and the strictest separation from clinical IT networks.

Educational Campuses

Large multi-building campuses with distributed BAS infrastructure across classrooms, labs, and administrative buildings - requiring consistent connectivity, central management, and clear IT/OT boundaries.
