Product Description
The NexaKey NX4000-G is a commercial-grade biometric access control and time attendance terminal engineered to deliver accurate identity verification, door security enforcement, and employee work-hour auditing across corporate offices, industrial manufacturing facilities, educational institutions, retail chains, and government premises. Designed with a clean, compact footprint and an understated Black housing, it mounts flush against interior walls or next to entrance doors, integrating smoothly into contemporary corporate workspaces.
Equipped with an enterprise optical fingerprint sensor and multi-mode authentication capabilities, the NX4000-G verifies users via fingerprint recognition, RFID card scanning, or individual secure PINs in under 0.5 seconds. Its biometric recognition algorithms are built to detect dry, wet, or lightly worn fingerprints with high fidelity, maintaining low false rejection and acceptance thresholds. The integrated color TFT LCD screen displays dynamic confirmation prompts, employee IDs, and live clock stamps, complemented by clear voice guidance and status indicator LEDs for immediate access feedback.
Beyond standalone time tracking, the NX4000-G features a complete suite of access control relays and terminal ports. The device interfaces directly with electric strike locks, magnetic locks, push-to-exit buttons, door sensors, and tamper alert buzzers. Support for standard Wiegand In and Out interfaces allows the unit to act as a primary standalone door controller or connect seamlessly into third-party security control panels and external slave readers for two-way access control.
Data communication is flexible and dependable, offering TCP/IP networking, USB flash drive logging for offline sites, and built-in Wi-Fi connectivity for wireless network environments. The terminal syncs with centralized NexaKey desktop and cloud-based attendance platforms, enabling HR and payroll personnel to monitor multi-shift schedules, overtime hours, department rosters, and automated shift rotations without manual paperwork. Backed by solid hardware construction and a 1-year warranty, the NexaKey NX4000-G Access Control & Time Attendance Terminal delivers a scalable and secure workforce management solution for modern enterprises.
