• New Proactive Facial Recognition
  • Enhanced Visible Light Facial Recognition
  • Anti-Spoofing
  • Recognition distance up to 3m long and extra wide angle 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.
