Low Voltage

Low voltage engineering is a vital part of modern infrastructure, enabling the systems that keep buildings smart, secure, and connected. In the U.S., demand is rising across sectors—from data centers and healthcare to commercial real estate and transportation—driven by digital transformation, security needs, and smart building technology.

What Is Low Voltage Engineering?

Low voltage systems operate at 50 volts or less and include:

• Structured cabling (fiber/copper)

• Security systems (CCTV, access control, intrusion detection)

• Fire alarm systems

• Audio/Visual & communications

• Building automation (BAS/BMS)

Key Markets

• Data centers & mission-critical facilities

• Commercial & mixed-use developments

• Hospitals & life sciences

• Airports, transit, and public infrastructure

• Industrial, manufacturing, and logistics sites

Industry Drivers

• Increased investment in smart buildings and IoT

• Expanding security and compliance requirements

• 5G rollout and high-speed connectivity demands

• Sustainability and intelligent energy management

In-Demand Roles

• Low Voltage Engineers & Designers

• RCDDs (Registered Communications Distribution Designers)

• Security & Systems Integrators

• Field Technicians & Cabling Installers

• Project Managers (Low Voltage Systems)

Challenges

• Talent shortages, especially in design and field installation

• Rapidly changing technology standards

• Coordination with MEP and general contractors on complex projects

Trends to Watch

• Convergence of IT/OT systems (network + operational tech)

• PoE (Power over Ethernet) adoption

• Cloud-based access control and remote monitoring

• Integration of AI and analytics in security systems

Low voltage engineering is no longer an afterthought—it’s a strategic layer in today’s smart, secure, and sustainable buildings. The U.S. market continues to grow, offering huge opportunities for skilled professionals and forward-thinking companies alike.
