Access Control Solutions

Scalable Access Control for Modern Facilities.

From single-door cloud solutions to enterprise-grade server environments, we design, install, and service the systems that secure your people and property.

Controlling Facility Access

Effective access control is about more than just locking doors; it is about managing the movement of employees, visitors, and contractors throughout your facility.

Whether you manage a multi-tenant office building requiring mobile credentials or an industrial plant needing strict perimeter logs, DSC engineers the logic and the hardware to make it happen. We move you beyond physical keys to a fully auditable, electronic environment that integrates seamlessly with your HR and security protocols.

Cloud-Hosted & Mobile

Cloud Native Access

For multi-site organizations and property managers, we deploy modern cloud platforms that eliminate local servers. These systems allow you to manage thousands of doors from a smartphone, issue mobile credentials instantly, and push over-the-air firmware updates without rolling a truck.

Enterprise Server Solutions

On-Premise Control

For government facilities, corporate campuses, and critical infrastructure, we engineer robust server-based systems. These platforms offer the deepest level of logic and data sovereignty, allowing for complex custom scripting, Active Directory integration, and strictly managed alarm monitoring.

Visual Verification

Unified Video Integration

"Access Granted" tells you a badge was used; it doesn't tell you who was holding it. We integrate your access control directly with video platforms like Avigilon and Hanwha Vision. Every forced door or propped entry triggers an instant video pop-up, giving your security team immediate visual context to respond faster.

Legacy Migration

You do not need to rip and replace everything to get a working system. We are a platform-agnostic integrator, capable of troubleshooting, repairing, and taking over service for nearly any commercial access control system—regardless of the original installer. We can often migrate your existing readers and cabling to modern controllers, saving you significant capital expense.

Mag-Locks & Strikes

The software is useless if the door doesn't physically latch. DSC technicians are experts in the electromechanical hardware that secures your facility. We install and service mag-locks, electric strikes, crash bars, and request-to-exit (REX) sensors, ensuring that your doors operate smoothly and meet all ADA accessibility standards.

Fire & Egress Integration

Security cannot compromise safety. We hardwire the critical interlocks between your access control panels and your Fire Alarm system. This ensures that in the event of a fire, specific secured doors automatically release to allow for safe, code-compliant evacuation, keeping you in good standing with the local Fire Marshal.

Certified Dealer Support

We do not force our clients into a single proprietary box. As a factory-authorized dealer for the industry's top manufacturers, we provide the certified warranty support and software maintenance your system requires.
