At GSP Security, we proudly provide professional security solutions for homes and businesses across the entire state of South Carolina. From the Upstate to the Midlands and the Lowcountry, our team specializes in designing and installing modern security systems, access control solutions, and video surveillance systems tailored to each customer’s needs.

As a locally owned and operated South Carolina security company, GSP Security is committed to delivering reliable protection, clean installations, and dependable service—no matter where you’re located.

Security is not one-size-fits-all. Every property, business, and facility has unique security requirements. That’s why GSP Security takes a solution-based approach, offering customized systems that provide real protection and peace of mind.

Our home security solutions help homeowners protect their property and loved ones with dependable intrusion detection, smart sensors, and mobile monitoring. Whether you live in a single-family home, townhome, or coastal property, we design systems that keep you connected and informed at all times.

We work with a wide range of commercial customers, including offices, churches, retail spaces, warehouses, and multi-site facilities. Our commercial security systems provide intrusion detection, real-time alerts, and scalable protection designed to grow with your business.

Access control is a critical part of any modern security strategy. GSP Security installs professional access control systems that allow businesses to manage and monitor who enters their facility, when they enter, and which areas they can access.

Our access control solutions include card readers, keypads, mobile credentials, and integrated door hardware that provide both security and convenience. From single-door installations to multi-location facilities, we help businesses improve security while simplifying daily operations.

Access control systems are ideal for:

• Offices and corporate buildings
• Churches and community facilities
• Retail and commercial spaces
• Industrial and warehouse environments

Video surveillance plays a key role in protecting property, monitoring activity, and providing valuable evidence when incidents occur. GSP Security designs and installs professional camera systems that deliver clear, reliable coverage day and night.

Our video surveillance solutions offer:

• Live and recorded video access
• Motion-based alerts
• Remote viewing from mobile devices
• Proper camera placement for maximum coverage

Whether you need a single camera or a multi-camera system, we ensure your surveillance system is installed correctly and built to perform.
