QEI Security & Technology is the third largest South Carolina-based security company.*

That means you get the benefits a large company can offer, while keeping the feel of a third generation family-owned business.

Free Equipment and Installation

We’re able to offer more than $1,000 of free equipment when you become a QEI Security & Technology customer – many local security companies are unable to afford this and require you to pay for equipment and installation. Check out our current security specials.

Offices in South Carolina’s Largest Cities

QEI Security & Technology has offices and technicians in Bluffton, Charleston, Columbia and Myrtle Beach. That means you’re not waiting hours for a technician to drive from another city to fix your alarm system.

Genuine QEI – No Authorized Dealers

QEI Security & Technology employs 25 people in South Carolina. You will always talk with a full-time QEI staff member and your account will not be sold to another company.

South Carolina’s Security Company

QEI Security & Technology is headquartered in Charleston. There are a lot of national and regional security companies who serve South Carolina residents, but none have headquarters in the state and few even have offices here. QEI is the third largest South Carolina security company – with headquarters in the state.*


*According to Hoover’s verified information as of April 2016, there are 95 South Carolina security companies and QEI Security & Technology is the third largest in number of employees and revenue.
