ESSL SF100 IP-Based Fingerprint Access Control is a biometric security system that uses a person’s unique fingerprint to grant or deny access to a secure location. The system can be integrated with an IP network, allowing for remote monitoring and management. It typically includes a fingerprint scanner and a control unit and may include additional features such as RFID card support, time and attendance tracking, and customizable access control settings.

The SF100 is an IP-based fingerprint terminal that works both in network and standalone modes. In network mode, it can connect with ZKAccess3.5 software for access control and time attendance management.

Wiegand output makes SF100 flexible to connect with ZK or any 3rd party controllers as a slave reader. Additionally, Wiegand input allows two units of SF100 to configure with each other and utilize the Master & Slave solution, which requires user verification at both entrance and exit. Meanwhile, the anti-passback function can be used to maximize security.

The auxiliary input interface allows SF100 to connect with an external source, for instance, a smoke detector or emergency switch. Once the linkage function is enabled through the machine menu, the device would generate an alarm signal and open the door in case of emergency.
