Who We are

DSX Access Control Systems, Inc.

Company Ownership and Integrity

In over 30 years the ownership of DSX has not changed. The company commitment is the same today as it was when the company was founded. Pride, Responsibility and Integrity permeate through the relationships of customers and actions of employees.

DSX Development Team

Although the development team has grown, the core engineers are still with DSX. This is the secret to progress with backward compatibility. Most companies have complete turnovers in development teams leading to compatibility and support issues. They no longer can support what they have built nor can they make the new products work with the old. DSX is constantly moving forward utilizing the latest in technology and development tools and bringing with them decades of experience.


Scalable Architecture

DSX has a scalable architecture that can grow from one door to thousands and from one PC to an Enterprise solution. The difference is that you only purchase what you need, where you need it. The system can grow with you without constant incremental expansion up-charges for more doors, people, and client workstation capacities. All WinDSX software is accompanied with a Site License so you only buy it once for your complete solution.



DSX provides outstanding Technical Support with technicians and engineers that have been in the business for decades accruing years and years of experience. Free Technical Support is provided to Factory Trained DSX Dealers. After hours emergency support is also provided at no cost. DSX provides certified factory training at no cost to Dealers and offers an End User class for a small fee. Software Maintenance can be purchased by the End User that allows them to call during normal business hours for software support. The agreement can be purchased anytime going forward. There are no back or retroactive charges that must be paid to buy the software maintenance at anytime in the future.


DSX Hardware

DSX designs and produces its own hardware. All DSX Hardware is designed, built and tested in Texas. This means DSX is not dependent on a 3rd party company or competitor to produce quality hardware. Our Hardware and Software development teams actually work together for complete solutions.



DSX Supports and Repairs most products ever built by DSX. Hundreds of thousands of controllers are in service with less than a .01% return rate. The repair of all products sold in over 30 years does not require a full time repair technician. That is quality you can rely on and reliability you can take to the bank.
