SenseFace 4 Series

SenseFace 4 Series adopts the latest intelligent engineering facial authentication and in-glass fingerprint technology. It supports fingerprint, facial, card authentication with large capacity and speedy authentication, adopts ultimate antispoofing algorithm for facial authentication against almost all types of fake photos and videos attack, which offering secure biometric authentication. SenseFace 4 Series is an access control terminal featuring a video intercom function and supports ONVIF protocol. It fully improves the video intercom experience and can be compatible with video intercom indoor unit with SIP protocol (Version 2.0). Besides, SenseFace 4 Series supports multiple communication protocols. Its firmware has AC push and can convert  to TA push and it is compatible with various AC or TA software. It can change to BEST protocol to link with ZKBio Zlink  (AC module).
