What We Do

One Door To Enterprise Wide, DSX offers simple scalability. Grow your system from one location and one PC to 32,000 locations and up to 999 PCs on a Wide Area Network. Intelligent Controllers and Integrated Locksets give DSX enormous flexibility and diversity. Take a look at the New DSX Software and features that is revitalizing Legacy systems and infusing them with new technology and wireless capabilities.

Software Licensing and System Growth

Start your system with one PC and one Door and grow it to the extent your organization requires. Once you have licensed the software to your Domain there are no licensing charges for growing it. You can add Card Holders, Doors, and Workstations without paying any additional licensing fees, just the cost of the hardware expansion itself. Maintenance and Support agreements are not mandatory.

Emergency Lockdown / Incident Response

Facilities of all types need an Incident Response Plan that includes the activation, action and notification of emergencies by locking down doors and altering access privileges all while notifying staff and authorities. Schools, Campuses, Hospitals and Business of all types using DSX can quickly reconfigure the access control system's operation and notify personnel of the emergency while initiating the appropriate action such as locking doors. First Responder Cards can be quickly altered to unlock every door although they don't unlock any door unless an Emergency is declared while onsite cards are completely revoked. WinDSX is a highly Integral solution that can be connected to other systems for a layered and well rounded approach.

Cardholder Check In Verify

Check-In Verify is a new feature by DSX that forces all cardholders within a Location to use a Check-In Verification Reader before their card will work at any other reader in the system. This Reader could be used in conjunction with Image Recall at a Security Checkpoint or it could be Facial Recognition or a Covid/Temp Reader. The second release of Check-In Verify allows for easy exclusion of readers and the ability to set an Automatic Check Out time. Read More

OSDP Reader Protocol

OSDP is an encrypted RS-485 two wire communications protocol that is the new industry standard for reader to panel communications. Some are advancing the foolish notion that you must replace every panel, reader and cable in between, to prevent your system from being compromised. This very expensive scare tactic becomes a non issue with a properly installed system and a very inexpensive tamper switch that most readers have built-in. Read More
