SF400

SF400 is an IP based fingerprint terminal with both Network and Standalone  operation modes. It is connectible with ZKBio CVAccess software for access control  and time attendance management. With Wiegand output, SF400 is flexible to connect with ZK or any 3rd party  controllers as a slave reader. Wiegand input configures two SF400 units to utilize  Master & Slave solution to enable users verification at both entrance and exit. Antipassback function is also enabled to maximize the security level. Auxiliary input interface allows SF400 to connect with an extra source, for instance, a  smoke detector or emergency switch. Once the linkage function is enabled through  the machine menu, the device generates an alarm signal and  opens doors in case of emergency.
