Visible Light Recognition

ZKTeco G4

Multi-Biometric Attendance & Access Control Terminal
with Enhanced Visible Light Facial Recognition


G4 is a multi-biometric identification terminal which features ZKTeco’s innovative Enhanced Visible Light Facial Recognition and SilkID fingerprint sensor technology. The device with latest
technologies can perform recognition in a distance from 0.5m to 3m and will function automatically when face are detected so as to deliver higher recognition quality in terms of
speed and accuracy than the previous near IR facial recognition. With the applied Deep Learning algorithm, pose angle tolerance and anti-spoof function have been greatly enhanced
against dynamic environment and various spoofing attacks. Also with the world’s cutting-edge 3D Neuron Fingerprint Algorithm, it precisely authenticates dry, wet, or rough fingerprints
efficiently and accurately.
