ZKTeco SF400 IP-based fingerprint reader terminal

The SF400 is an IP-based fingerprint terminal with both Network and Standalone operating modes. 
With its Wiegand output, the SF400 offers flexibility in connecting as a slave reader to a ZK or any third-party control device. The Wiegand input configures two SF400 units to use a Master & Slave solution, allowing users to verify both entry and exit. An anti-passback function is also enabled to maximize security.
The auxiliary input interface allows the SF400 to connect to an extra source, such as a smoke detector or emergency switch. When the connection function is activated from the machine menu, the device generates an alarm signal and opens the doors in emergencies.
