DSI History


Since 1982, Designed Security, Inc. has been developing, engineering, and manufacturing custom and standard state-of-art security and access control peripheral products for the corporate, commercial and industrial marketplace.


DSI was founded as a result of an industry need for innovative products that would be designed to enhance the performance of security and access control systems. In response to a security requirement, the first product that was developed was the Door Management Alarm. The “DMA” has undergone significant modifications and today the enhanced ES4200 remains unique in the industry and continues to be recognized as an effective solution for a variety of access control and security system requirements.

The DSI product offering has matured into four distinct product groups: Door Alarm Products, Annunciator products, Optical Turnstiles, and Mechanical Turnstiles. The Door Alarm Products include a complete line of door management peripheral devices that provide for stand alone controlled access or enhance the performance of any access control system. The Annunciator Products are modular in design and display the status of security devices and alarm conditions throughout a facility. The Optical Turnstile Products provide High-speed, Barrier-free, or Non-Restrictive Barrier Arm version, effective pedestrian control in building lobbies  where aesthetics  and pedestrian throughput are of concern. Full-height Mechanical Turnstiles provide a more restrictive solution for pedestrian control. The DSI Tailgate Detection System is unique in the security industry and can be used to restrict and record unauthorized access at doors. These products comply with the Americans with Disabilities act of 1990/ADA, and provide Equal Access, as well as Fire/Life Safety Code 101 and local building code requirements.

DSI custom products continue to be engineered and developed under a sustained joint effort relationship with electrical engineers, security consultants, and system integrators to meet the ever-changing security product demands as well as specific project requirements.

Most of the standard and custom products, including the electronic subassemblies, are designed, engineered, manufactured, tested and shipped from our 12,000 square foot facility in Bastrop, Texas. Our skilled personnel and modern facility allow us to provide and control all aspects of product fabrication, manufacturing,  and testing  in-house. This includes: All electronic assemblies, board wave solder, metal fabrication, laminating, painting, silk-screening, board burn-in, and final test. This total command of production allows for greater controls over product quality, reduces lead-time and improves customer service. This also provides for cost effective limited production runs of products that require modifications to meet a specific project requirement.

A primary component of DSI business philosophy is to provide our customers with comprehensive engineering and technical support for all our products. We believe that effective communication and technical assistance during product evaluation, as well as after the sale, have substantially contributed to product acceptance, enhancements, and customer satisfaction.

Designed Security, Inc. security products are marketed, distributed and supported by a national and international security system integrator network.

DSI is a wholly-owned subsidiary of the Detex Corporation.
