Professional Home Security Installations Across Charleston

We proudly offer an extensive, localized home security service across Charleston. Wherever you live in the city, our installation experts will be on hand to fit your tailored system.

We’re Carolina natives, with in-depth knowledge of Charleston and the surrounding areas. You don’t get to serve local neighborhoods for over 30 years without becoming experts.

We cover the whole of Charleston, but here are some of the main areas.

Harleston Village

Harleston Village dates back to the 1700s. A busy residential and business area in Downtown Charleston, it’s popular with young couples, families, and professionals alike. You’ll find large homes, colonial-era properties, and gorgeous tree-lined streets. Whatever your property type, a CPI security system can offer peace of mind in the middle of the busy city.

Mount Pleasant

This large suburb is just a bridge away from vibrant Downtown Charleston. This area has an eclectic mix of properties, people, and public attractions. You’ll find historic homes and townhouses, but also modern properties—perfect for families and professionals. Protect your piece of Mt Pleasant, and the people you love, with a home security system.

South of Broad

This area is known for its southern charm. Idyllic streets, large properties, and green spaces adorn this neighborhood, but there is also variety to be found here. We fit security systems in South of Broad condos, family homes, apartments, townhouses—and more. Whatever your property type, tailor your home security with CPI.

Summerville

Summerville offers beautiful historic properties—but you’re also likely to find affordable homes in this area just north of Charleston. This large neighborhood counts good schools, golf clubs, and great access to the city center among its selling points. There are also many inherited properties in the area, so a CPI system could be perfect if you’re looking to protect your family home and heirlooms.

James Island

Separated from the mainland by the Stono River, the James Island neighborhood is popular with families, young couples, and professionals due to its proximity to Downtown and great area schools. There’s a tight-knit community here—so it’s no surprise that many people have decided to buy homes on this cozy urban island. If you’re looking to protect your home and family, consider a CPI security system.

West Ashley

West Ashley has been called a perfect neighborhood for families and first-time buyers. It sits west of Downtown Charleston, meaning there’s a variety of property types—including condos, townhouses, and apartments. Bordered by the Ashley and Stono Rivers, there’s a laid-back waterfront vibe here. Install a home security system for peace of mind on your river-front walks.

What Our Home Security System Customers Say

Our customers are at the heart of our business—it’s why we’ve spent the last 30 years doing what we do. But don’t just take our word for it—see what they have to say.

Trustpilot 5 Star Review | CPI Security

Robyn was so wonderful helping me get…

“Robyn was so wonderful helping me get set up as a new user! She literally guided me through each step throughout the day to make sure my needs were met. That type of interaction makes me feel like the company I’m working with actually cares, and will not ignore my requests once I’m actually set up. She even understood the work schedule I had at hand and was willing to wait me out until my tasks were complete. In addition she had a great sense of humor! 10 stars for sure!”

– Israel H., Trustpilot

Trustpilot 5 Star Review | CPI Security

Excellent Service

“Starting with Earnest (Sales/Marketing) was very patient, kind, and very knowledgeable. The technician, Skylar, was patient, kind, and very knowledgeable in installing the system. He explained every aspect of how to use the system using various “test” scenarios. I started to feel very safe. I would highly recommend both!”

– Edna, Trustpilot

Frequently Asked Questions

How much does a CPI home security system cost?

This depends on what you choose to include in your CPI home security system. The more tech you include (for example, indoor and outdoor cameras, motion sensors, and alarms), the more expensive it will be. All our systems are fully customizable to suit you and your family’s needs, so everything is up to you. You can contact us today to get a free quote.

How do I pay for my CPI Security home security package?

You can pay for your home security package equipment in two ways, up-front with a credit card or in installments through CPI Smart Pay. CPI Smart Pay allows customers with approved credit to pay for their equipment in installments over 39 or 60 months at 0% APR. A monthly monitoring agreement is required for the length of the installment term.

Monthly monitoring fees vary depending on the equipment you have installed at your home or business. Monthly monitoring can be paid for through ACH, which allows customers to make payments via direct debit from their bank account.

What other cities than Charleston does CPI Security cover?

We cover hundreds of cities across the southeastern US. In fact, we cover all cities in North and South Carolina, and portions of Georgia and Tennessee—so wherever you are, you can rest assured that we’ll be there to protect your home.

What happens on my CPI Security installation day?

On the day you’ve chosen, the technician team will arrive to your Charleston home knowing exactly what you’ve purchased. They’ll install the system, explain how to operate it, and discuss options for customization based on what they learn about your home that day. They will not leave until they are sure you’re comfortable operating the equipment and completely satisfied with the installation.
