Why Choose Networked Access Control?
Networked access control systems provide centralized management and real-time monitoring for multi-door installations, allowing security teams to manage access rights, monitor events, and control doors remotely from a single interface. The Norpass3 system offers advanced features including real-time event logging, comprehensive reporting, and remote door control across up to 128 doors.
Unlike standalone systems that operate independently, networked solutions connect multiple door controllers via TCP/IP or RS485 to centralized management software. This enables instant updates to access rights across all doors, immediate notification of security events, and comprehensive audit trails for compliance. Nortech's Norpass3 software is license-free, running on standard Windows PCs with an integral web server supporting multiple workstations without additional software installations.
The modular CRC controller range (CRC221-1, CRC221-2, CRC220-4) offers flexible configuration options from single-door to four-door control per panel, with support for up to 65,000 users. Controllers support both Clock & Data and Wiegand reader interfaces, making them compatible with virtually any card reader technology. Optional features include Card & PIN security, buddy mode authorization, anti-passback, and integration with biometric readers.

Networked access control provides centralized management of multiple doors from a single interface, allowing real-time updates to access rights across your entire facility. When you add or remove an employee, changes are instantly applied to all doors rather than requiring manual updates at each controller. You gain real-time event logging, comprehensive reporting for compliance audits, remote door control, and advanced features like anti-passback and time-based access schedules. Networked systems are ideal for facilities with 3+ doors requiring centralized oversight, while standalone systems suit 1-2 door applications.
The Norpass3 access control software can manage up to 128 doors across your facility using a combination of networked door controllers. You can mix and match controller types based on your needs: CRC221-1 for single doors, CRC221-2 for two doors with full read-in/read-out, or CRC220-4 for up to four doors with read-in and free exit. Up to 32 controllers can connect to each RS485 port, and you can add multiple ports for larger installations. The system supports up to 65,000 users with comprehensive access level management.
Yes, Norpass3 is completely license-free with no recurring fees or subscription costs. Unlike many competitor systems that charge annual software licenses per door, user, or workstation, Norpass3 has a one-time purchase cost with no ongoing software fees. The system includes an integral web server that supports additional workstations without requiring software installation on each PC, reducing both initial and long-term costs. This makes Norpass3 one of the most cost-effective networked access control solutions available.
Yes, Norpass3 and the CRC controller range support advanced security features including biometric fingerprint readers, Card & PIN verification, buddy mode (requiring two authorized users for access), and sophisticated anti-passback rules to prevent credential sharing. The system includes integral fingerprint management for biometric readers, picture pop-up displays showing cardholder photos when cards are presented, and configurable access levels with time-based restrictions. You can tailor security levels to match specific door requirements—from basic card-only access to multi-factor authentication for high-security areas.
