As a leading manufacturer of security devices, Portman has been dedicated to supplying audio systems, car alarms, and home security systems for over two decades. Established in 1983, Portman began as a manufacturer of sirens and quickly built a solid reputation based on the advanced design and exceptional reliability of its products. This successful beginning fueled a rapid expansion into the vehicle and home security systems markets.
In order to achieve the goal of becoming a preferred source in a global environment, Portman established manufacturing operations in China in 1991. With 100,000 ft2 of state-of-the-art manufacturing and assembly technology (including vertical capabilities in tooling, injection molding, die -casting, and SMT lines), the China facility has become the heart of the Portman Group and is delivering superior products to 62 countries worldwide! In addition to its offices throughout China, Portman established its Americas Regional Headquarters in the Eastern United States to deliver unparalleled service in the markets where it sells. The decision to enter the international marketplace has proven to be very successful.
