National Security, Inc. is a privately owned, local company that began business in 1979.  Our main office is located in Fairfax, Virginia and we service all of the DC Metro area. 

We are just the right size company: large enough to handle all your security needs, but small enough to still have a personal touch so that each customer is important and appreciated.  We have grown from a handful of employees to currently twenty-five employees.  Many of our employees have been with the company from the beginning and have shared in our growth. 

We have expanded our product line to include not only alarms, but also access control, CCTV, audio, home theater, intercoms, telephone systems, and almost every kind of low voltage wiring product. 

We have technicians available 24-hours a day for emergencies and friendly operators to offer telephone assistance.  All of our employees are registered with the Virginia Department of Criminal Justice Services and have national background checks performed.

Our goal has always been to provide friendly, superior service at a competitive price.  We are proud that much of our business comes from referrals from current customers.  We hope you will become one of our many satisfied customers and allow us to serve your security needs.
