ZKTeco G4 Pro Multi-Biometric Access Control Terminal (Fingerprint, Face & Card)

Description

ZKTeco G4 Pro is a multi-biometric access control terminal for Bangladesh offices, factories, and institutions, verifying identity through fingerprint, face recognition, or ID card in a single device, with anti-spoofing protection and high user capacity built for growing organizations and multi-entry access control.

Key Features of ZKTeco G4 Pro

• Triple authentication modes: fingerprint, AI facial recognition, and RFID card, letting each entry point use the method that fits best.
• High user capacity: supports up to 30,000 fingerprints, 50,000 face templates, and 50,000 ID cards, with 1,000,000 log records for large organizations.
• Anti-spoofing and liveness detection: blocks photo, video, and mask-based spoofing attempts, keeping access logs trustworthy.
• Mask detection: maintains recognition accuracy even when users wear masks.
• Android 9.0 operating system: supports third-party application integration through ZKTeco’s LCDP development tools.
• PoE (802.3af/at) power supply: simplifies cabling and installation across multi-door or multi-floor sites.
• Optional 4G connectivity: keeps devices online for remote sites or buildings without stable wired internet.
• Multi-tech card module: reads both 125kHz and 13.56MHz card formats, plus QR code scanning for the ZKBio mobile app.
• Multiple communication interfaces: TCP/IP, USB-Host, Wi-Fi, and OSDP support flexible integration with existing systems.
• Built-in camera: captures a visual record alongside each access event for audit purposes.

Why Choose ZKTeco G4 Pro?

Single-method access control creates single points of failure: a scratched fingerprint sensor, a lost ID card, or poor lighting can lock out a legitimate employee. The G4 Pro solves this by supporting fingerprint, face, and card recognition in the same terminal, so each entry point or department can use whichever method fits, without buying separate hardware.

Its AI-driven facial recognition includes anti-spoofing protection against photo and video attacks, and continues working reliably even when users wear masks or in challenging lighting, a common issue with older near-IR systems.

Bangladesh Real-World Performance Note: PoE power supply keeps the terminal running through office voltage fluctuations and load-shedding when connected through a UPS-backed switch, and optional 4G connectivity keeps attendance logs syncing even during building network outages, both common concerns for multi-site BD organizations.
