Serving residential and commercial customers throughout New Hampshire and Massachusetts, especially in Hillsborough County and Rockingham County, NH, as well as Middlesex, Norfolk, Essex, and Suffolk counties in MA, including cities such as Manchester, Nashua, Portsmouth, Boston, Cambridge, Newton, Waltham, Lexington, and surrounding areas, as well as Cape Cod, Nantucket, and Martha’s Vineyard.

Security system installation that makes you feel calmer the moment it’s done.

When people search for Security System Installation, they’re usually not shopping for gadgets. They’re shopping for peace of mind. They want to know their home or business is protected, that the system is installed correctly, and that it will actually work when it matters.

That’s why professional installation is so important. A security system is only as reliable as the setup behind it. If sensors are placed poorly, wiring is sloppy, or the system is not configured correctly, you end up with false alarms, dead spots, inconsistent triggers, or that constant feeling of “I hope this works.”

High Voltage Electric INC approaches security as a structured, low-voltage electrical project. We plan device placement logically, install clean low voltage wiring when needed, and set up an alarm system in a way that feels stable and easy to use. Whether it’s home security system installation or a commercial security system install, we focus on clarity, clean workmanship, and long-term reliability.

Structured low voltage wiring

We handle low voltage wiring cleanly so your system is stable and service-friendly later.

Home or commercial planning

We can set up both home security system installation and commercial security system projects with the right approach for each environment.

Getting Security System Installation is easy when your installer follows a real process.

Four steps that keep the install clean, reliable, and stress-free.

Tell us what you’re protecting

Home, business, entry points, sensitive areas, and what kind of coverage you want.

Step 1

We plan placement and wiring

We recommend device placement, confirm signal needs, and plan low voltage wiring if required.

Step 2

We install and configure the alarm system

We complete professional installation, configure the alarm system, and confirm stable triggers.

Step 3

We test and show you how to use it

We test the system, verify coverage, and walk you through daily use so it feels simple.

Step 4

Security system installation pricing depends on device count, wiring needs, and the type of property.

Pricing is usually driven by how many sensors you want, whether the system includes keypads or additional components, and whether low voltage wiring is needed to support stable placement. Homes typically require fewer devices than commercial spaces, while a commercial security system may require more planning and more coverage points. We provide clear estimates so you can choose the right setup before installation begins.

Security Installation Service	Typical Range
Basic home alarm install (starter setup)	$350 to $1,200
Expanded home security system installation	$900 to $3,500+
Low voltage wiring support (as needed)	$250 to $2,500+
Commercial security system installation (light commercial)	$1,200 to $8,000+
