Wireless Security for Historic Buildings & Concrete Structures

We specialize in wireless security camera installation for historic buildings and buildings with thick concrete walls. Most Wi-Fi cameras and wireless network devices fail when the signal needs to penetrate concrete walls. This is especially common in Duluth, where many buildings were built with thick concrete walls which absorb wireless signals, causing unreliable wireless camera links. Running cables is often not an option in historic buildings, so in these cases we will use mission-critical wireless bridge links. Wireless bridges are not typical consumer Wi-Fi links which are weak and unreliable. A wireless bridge is as close as possible to having a physical wire which penetrates the wall without physically affecting it. This provides a resilient backbone to keep your security cameras connected to your network despite all the challenges of typical Wi-Fi connections.

The Problem:

🚫 Why Standard Wi-Fi Security Cameras Fail in Duluth's Historic Buildings

• Thick Concrete/Brick Walls: Standard Wi-Fi signals often cannot penetrate the 12-inch or thicker walls common in our historic structures. The result: constant signal dropping and gaps in video coverage.

• Long Distances: Wi-Fi's range is limited. We need reliable coverage across a large building or campus—something consumer-grade Wi-Fi simply can't deliver.

• Low Reliability: Wi-Fi is prone to interference and network slowdowns, meaning your security system may be offline when you need it most.

The Solution:

✅ Our Proven Solution: AI-Powered Wireless Bridge Links

Duluth Security Needs specializes in custom wireless bridge links—a commercial-grade, point-to-point network that is fundamentally different from consumer Wi-Fi.

• Resilient Signal: Our bridges can transmit stable, high-definition video through concrete and over long distances.

• No Drilling Required: Preserve your building's historic integrity with non-invasive wireless installation.

• Dedicated Bandwidth: Unlike shared Wi-Fi, our bridges are dedicated to your security system, guaranteeing reliable data transmission for your AI/CV analytics and live monitoring.
