Enhanced Visible Light Facial Recognition is the latest technology of ZKTeco, aimed to overcome shortcomings of previous facial recognition and achieve an all-rounded upgrade on whatever performance and reliability. G4L is a multi biometric identification terminal, notably offers enhanced Visible Light facial recognition and SilkID fingerprint authentication technology.

Compared with other near-infrared facial identification devices, G4L, equipped with advanced Visible Light Facial Recognition technology, enables quicker automatic face detection and facial recognition when a target enters its detection distance from 0.5m to 2.5m.

With new deep learning algorithms applied, the anti-spoofing technology performance has been dramatically heightened and can prevent different types of photos and video attacks.

Also, with the cutting-edge 3D Neuron Fingerprint Algorithm, G4L precisely authenticates dry, wet, or rough fingerprints efficiently and accurately. Apart from Visible Light facial recognition and SilkID fingerprint authentication, G4L also supports identification with RFID cards and passwords.
