Why Strong Network Infrastructure Is the Backbone of Modern Security Systems

Written By Drew Horning

Commercial security systems are more advanced than ever—but their performance depends on one often-overlooked factor: the network behind them. Cameras, access control, alarms, and remote monitoring tools all rely on structured cabling, stable PoE power, and properly designed network infrastructure.

At Tier One Technologies, we see the same problems repeatedly when security systems fail: underpowered switches, Wi-Fi-dependent devices, outdated cabling, and networks never designed for 24/7 security workloads. In this post, we break down why your network matters and how proper infrastructure dramatically improves reliability, uptime, and visibility.

1. Security Devices Are Only as Reliable as Their Network

Your cameras and access control hardware can be top-tier, but if the network is weak, you’ll experience:

  • Video dropout

  • Frozen camera feeds

  • Missed motion events

  • Access control delays

  • System disconnects

This is especially common in older buildings or rushed installations where networking wasn’t prioritized.

A strong network ensures every door panel, camera, and controller stays connected 24/7.

2. Structured Cabling Prevents Failures and Reduces Future Costs

Professional Cat6/Cat6A cabling provides:

  • Stable data transmission

  • Longer lifecycle performance

  • Less interference

  • Higher bandwidth for future upgrades

  • Cleaner, easier-to-service pathways

Cutting corners on cabling leads to long-term reliability problems and expensive fixes later.

Tier One Technologies installs commercial-grade structured cabling designed specifically for security systems—not just office IT.

3. PoE Switches Power More Than Cameras

Most modern security devices rely on PoE (Power over Ethernet), including:

  • IP cameras

  • Access control readers

  • Door controllers

  • Intercoms

  • Wireless bridges

Proper PoE budgeting is critical. Undersized switches are one of the biggest causes of device failures.

We calculate PoE draw for every device to ensure your system has the power it needs both today and as you scale.

4. VLAN Segmentation Improves Security and Performance

Commercial networks should never mix:

  • Cameras

  • Access control

  • Office computers

  • Guest Wi-Fi

Segmenting these networks improves:

  • Cybersecurity

  • Traffic performance

  • Troubleshooting

  • System uptime

Many businesses don’t realize how much network congestion affects camera and access control performance until separating the traffic solves the issue instantly.

5. Remote Management and Monitoring Reduce Downtime

With a properly designed network, businesses benefit from:

  • Remote troubleshooting

  • System health dashboards

  • Automated alerts

  • Centralized updates

  • Faster support responses

Network design is what makes proactive monitoring possible.

6. Planning Infrastructure Early Saves Thousands Later

For new construction or renovations, early low-voltage planning means:

  • Proper conduit

  • Correct cable pathways

  • Power placed where needed

  • MDF/IDF closet preparation

  • Server and NVR room design

  • Avoiding costly rework

Tier One Technologies works with builders to make sure security, networking, and automation are fully planned on Day 1—not after drywall is up.
