We design a system that perfectly matches your needs.

At National Security, we believe that a security system should be as individual as the person who uses it and depends on it. We don’t believe that a system can be stamped from a mold and sold as if “one size fits all.” We take the time to get to know you and find out your unique needs and expectations.

One of the greatest advantages of the GE Security Pro line is flexibility. It allows us to customize a system specifically for you. You’ll end up with a system that works out best for you and your budget.

Expert installation is another National Security advantage. Our trained technicians are uniquely qualified to install your system neatly, efficiently and reliably.

We provide service around the clock. It’s available 24 hours a day, seven days a week, including holidays. Burglars don’t work on a time clock and they don’t take vacations. So neither do we.

We’ll always strive to have your system operating at a peak performance. If you should ever have a problem, you can rest assured that we will respond quickly to resolve it.
