What Is Low Voltage Work in Commercial Buildings?
Low voltage refers to systems operating under 50 volts, including:
- Voice and data cabling (Ethernet, fiber)
- Audio-visual systems
- Security cameras and surveillance
- Fire alarms and paging
- Access control and badge readers
- Wi-Fi infrastructure
- Smart building automation
Unlike high-voltage electricians, low voltage contractors focus on systems that transmit information and control signals, not power.
These systems often run on structured cabling, using industry standards such as:
- Category 5e / 6 / 6A cabling for data and phones
- Fiber optic cabling for high-speed, long-distance connections
- Shielded cables for AV and specialized signal paths
Low voltage contracting isn’t just about pulling cable. It’s about system design, code compliance, signal integrity, and future-proofing. That’s why most commercial projects in Minneapolis hire licensed, experienced contractors who understand the local codes, weather conditions, and tech requirements.
Why You Need a Low Voltage Contractor (Not Just an Electrician)
Licensed electricians bring essential high-voltage skills, but they typically do not design for information, communications, or integrated systems.
Low voltage specialists deliver:
- Certifications in ANSI/TIA‑568, BICSI, and UL labeling
- Structured cabling designs built for future growth
- Systems engineered for data, AV, and automation workloads
- Integrated access control, surveillance, and smart tech support
- Proven techniques for signal shielding and grounding
Projects follow standards like NEC Chapter 8 and require proper documentation, labeling, and permitting. Low voltage contractors reduce compatibility risks, deliver cleaner installs, and provide more organized infrastructure and systems that just work.
Structured Cabling Installation: The Backbone of Modern Offices
Let’s start with the core of low voltage contracting: structured cabling installation. This is the organized system of wiring that supports your:
- Internet and phone service
- Security camera system
- Audio and visual equipment
- Building automation
- Wireless access points
At Northland Sight & Sound, our systems are designed for both speed and scalability.
Why It Matters
A messy cabling job might work but only until you add another user, a new conference room, or a few more devices. Then things start to fail.
Structured cabling is built to:
- Scale as your company grows
- Minimize interference between systems
- Simplify upgrades and maintenance
- Keep your network reliable and secure
For Minneapolis-area businesses, investing in a professional structured cabling installation avoids costly retrofits and downtime later.
Commercial AV Systems: Seamless Integration, Better Communication
In today’s commercial spaces, audio-visual systems are no longer optional, they are essential to daily operations, productivity, and client engagement. Whether you run a conference-heavy office, a showroom, a school, or a house of worship, your AV systems should be designed to enhance how people share information.
A low voltage contractor is responsible for integrating all these systems so they perform reliably and cohesively.
Common AV Installations Include:
- Conference room systems: Projectors, flat panel displays, wireless screen sharing, microphones, speakers, and room controls
- Digital signage: Lobby displays, wayfinding screens, menu boards, and promotions
- Sound systems: Zoned audio, background music, overhead paging, and live performance systems
- Video walls: Large multi-display solutions for control rooms or large-scale presentations
- Broadcast & streaming systems: Live feed setups for hybrid events or remote collaboration
- Control systems: Wall-mounted or wireless interfaces that control lights, blinds, AV, and HVAC from one panel
Low voltage contractors ensure these systems are not only installed cleanly and professionally but also integrated into your building’s infrastructure. That means power, network, and control all run smoothly behind the scenes, with no unsightly wires or unreliable connections.
What We Do Differently
At Northland Sight & Sound, we design AV systems with usability in mind. We don’t just drop equipment and leave, we ensure it works with your space, your team’s workflows, and your overall goals. Whether that means setting up touchless screen sharing or automating the entire room for single-button operation, we make it simple.
Smart Tech and System Design Services
Commercial buildings today are smarter than ever, and low voltage contractors are the ones making it happen behind the scenes.
These systems are unified, not siloed. Our designs connect everything through one infrastructure, making them easier to control, manage, and expand. That includes:
1. Access Control & Security
- Card readers, keypads, biometric scanners
- Integration with camera systems
- Scheduled access, remote unlocks, event logs
2. Video Surveillance
- IP camera installation
- Centralized network video recorders (NVR)
- Remote monitoring through mobile or desktop apps
3. Paging and Intercom
- Overhead paging for retail or industrial spaces
- Zoned systems with priority override
- Two-way office intercoms or nurse call systems
4. Sound Masking
- Ambient noise systems for open offices
- Enhances privacy and reduces distractions
- Often integrated with paging or AV systems
5. Smart Building Automation
- Centralized control over lighting, HVAC, shading, and security
- Integration with BMS (Building Management System) platforms
- Automated scheduling, energy monitoring, and occupancy sensing
These aren’t standalone systems. They’re designed to work together, tied in through a unified infrastructure managed by your low voltage team.
The Typical Low Voltage Project Process
So how does a commercial low voltage project actually work? Here’s the typical process from start to finish:
1. Needs Assessment
We begin by understanding your building and business needs. Whether you’re a law firm, school, or retail space, we ask the right questions up front.
2. Site Survey and Design
We visit your space to evaluate building materials, cable pathways, existing systems, and potential obstacles. Then we draft a structured design that includes:
- Equipment selection
- Access point and device placement
- Cable routes
- Power and network dependencies
- Compatibility considerations for existing tech
3. Permits and Scheduling
We coordinate with local Minneapolis inspectors to ensure our plans meet building codes, and we schedule the project in phases that minimize disruption to your operations.
4. Installation
Our team handles every part of the installation, including:
- Pulling and terminating cable
- Mounting equipment
- Setting up racks and cabinets
- Installing wall plates, control panels, and AV mounts
- Testing each line and device
5. Testing and Commissioning
We run tests on all cables (signal loss, speed, interference), verify devices are functioning, and train your team on system usage.
6. Documentation and Support
Every project ends with documentation and optional support for future updates and growth.
What Does It Cost to Hire a Low Voltage Contractor?
Commercial low voltage projects vary widely in cost depending on:
- Building size and layout
- Type of systems installed (AV, access, cabling, etc.)
- Number of devices, cable runs, and access points
- Type of cable (Cat6 vs. fiber) and hardware quality
- Any integrations or automation systems required
- Local permitting and labor time
