Access Control Systems
What Is an Access Control System?
An access control system is an electronic security solution that manages who can enter specific areas of a building or facility, and when. By verifying identity and credentials at designated entry points, these systems replace traditional lock-and-key methods with intelligent, programmable security — giving organizations precise command over physical access at every door, gate, elevator, and barrier.
Nationwide Security Corporation (NSC) has been designing and installing commercial access control systems throughout Connecticut and Rhode Island since 1983. Every deployment begins with a personalized consultation so our engineers can understand the unique layout, workflow, and risk profile of your facility.
How Access Control Works
Modern electronic access control systems use a combination of credential readers, electronic locking hardware, and centralized software to grant or deny access. Access can be permitted or restricted based on a specific person, a designated entry point, time of day, or day of week — providing layered, customizable security.

Electronic Door Hardware — End-to-End
Each access-controlled door can incorporate multiple components: a credential reader, door position switch, request-to-exit (REX) device, and electronic locking hardware. NSC specifies and installs all electronic door hardware in-house — we do not rely on secondary hardware vendors — ensuring seamless installation and single-point accountability for service.
System Integration Capabilities
Access control systems are most powerful when integrated with the broader security ecosystem. NSC specializes in connecting access control to:

- Video surveillance and management systems (VMS)
- Intercom and two-way communications
- Fire detection and life safety systems
- Perimeter security (turnstiles, gates, fence detection)
- Visitor management software
- HR and identity management platforms

Frequently Asked Questions
What types of businesses need access control?
Any organization that needs to restrict access to sensitive areas — corporate offices, data centers, schools, hospitals, government buildings, museums, and manufacturing facilities — benefits from electronic access control. NSC serves clients of all sizes across Connecticut and Rhode Island, and national accounts.
Can access control integrate with my camera system?
Yes. NSC specializes in integrated security, linking access control with video surveillance so every access event is associated with a timestamped video record, making investigations faster and management more efficient.
How are user permissions managed?
Access rights are managed through a central software platform. Administrators can add or remove users, adjust permissions, set time-based schedules, and run activity reports from on-site workstations, secure web portals, or mobile devices.
What happens during a power outage?
NSC systems use battery backup and fail-safe or fail-secure locking hardware depending on the application, configured appropriately for life-safety requirements and your operational needs.
