Welcome to the standard of excellence in commercial security.

DMP is a family-owned independent manufacturer of intrusion, fire, access control and cellular alarm solutions. All DMP products are designed, engineered and manufactured in America with U.S. and global components. Our factory, call center, engineering and distribution are all located in Springfield, Missouri, right where the business began more than 45 years ago.

Made in the USA with U.S. and Global Components

“Made in the USA” is something you rarely see today. More and more products are made elsewhere. Like other manufacturers, DMP must rely on some components that are not indigenous to the U.S.

Manufacturing in the U.S. builds a tighter partnership with our customers as well as our community. We are honored to be a part of Springfield and employ area residents who are dedicated to our industry and our dealers.
