Zkteco K-30 Fingerprint Reader and proximity card reader / TCP-IP / Relay Output

The ZKTeco K-30 is a wall-mounted terminal that combines fingerprint biometric recognition with proximity card reading to deliver dual-mode identity verification at controlled entry points. Designed for professional access control and workforce management deployments, it communicates over TCP/IP networks and provides a relay output that interfaces directly with electric locks, magnetic locks, and door strike hardware. The unit accepts a request-to-exit input, making it suitable for compliant two-way door control wiring. Because enrollment and verification are handled on the device itself or through centralized management software, installers can commission the terminal as a standalone access point or integrate it into a broader networked security infrastructure. The K-30 is well suited for office environments, commercial facilities, light industrial sites, and any application where organizations need to enforce door access policies while simultaneously capturing accurate attendance records for employees or contractors. Its relay output and TCP/IP backbone make it a practical fit for IT-managed physical security platforms where central monitoring and audit logging are operational priorities.

Key features & benefits

• Dual Verification Modes — Supports both fingerprint biometric authentication and proximity card reading, giving installers and administrators flexibility to assign credential types based on user roles or security policy requirements.
• TCP/IP Network Connectivity — Integrates directly into existing Ethernet infrastructure, enabling centralized enrollment management, real-time event monitoring, and remote configuration without requiring dedicated communication cabling.
• Relay Output for Lock Control — Provides a built-in relay output that connects to a wide range of electric locking hardware, allowing the terminal to directly control door access without an intermediate control panel in basic deployments.
• Request-to-Exit Input Support — Accepts a REX button or sensor input, supporting code-compliant egress wiring and simplifying installation in doors that require both entry control and free exit.
• Time and Attendance Integration — Records check-in and check-out events natively, allowing the same device to serve both physical access control and workforce attendance tracking functions, reducing hardware overhead.
• On-Device or Software Enrollment — Users can be enrolled directly at the terminal or through compatible management software, providing installers and administrators with deployment options suited to small single-door sites or larger multi-reader installations.
• Backup Battery Operation — Continues to function during power interruptions, maintaining access control integrity and protecting attendance records even when primary power is unavailable.
