Product Description

The SF300 is an IP based fingerprint terminal, which operate in both network mode
and standalone mode. it can connect with ZKAccess3.5 software for access control
and time attendance management.
Wiegand output makes SF300 flexible to connect with ZK or any 3rd party
controllers as a slave reader, Additionally, wiegand input allows two units of SF300
to configure with each other and utilize Master & Slave solution, which requires user
verification at both entrance and exit. Meanwhile, anti-passback function can be
used to maximize the security.
Auxiliary input interface allows SF300 to connect with an external source, for

enabled through the machine menu, the device would generate an alarm signal
and open the door in case of emergency.
