Multi-functional Access Control and Time Attendance Device - SF400

Multifunctional Access Control and Time Attendance Device - SF400 with Flexible Wiegand Integration

In today's context, ensuring effective security and access control at businesses, factories, offices, or sensitive areas is an increasingly urgent requirement. With modern technology, flexible integration, and stable operation, the SF400 from ZKTeco is an IP-based fingerprint access control and time attendance device, possessing many outstanding features for professional security systems.

1. Modern Design – Convenient Touch Screen

SF400 features a compact design with dimensions of only 105 x 105 x 32mm, suitable for flush mounting or surface mounting in various locations. The device boasts a 2.8-inch capacitive touch screen, offering sharp display and easy operation. Users can query data, register fingerprints, cards, and passwords directly on the screen with ease, without needing a computer.

2. Fast Authentication – Ample Capacity

The device uses a high-quality ZK optical sensor (500 DPI), providing fast recognition speed and high accuracy, even with blurred or sweaty fingerprints. The SF400 can store:

• 1,500 fingerprint templates

• 80,000 transaction records

This makes the device suitable for small and medium-sized businesses, workshops, or offices with 30 to 100 employees.

3. Flexible Connectivity – Supports Multiple Protocols

The SF400 supports both Standalone and Network modes through the following protocols:

• TCP/IP: Easily connects with ZKAccess 3.5 management software, synchronizing real-time data.

• USB Host: Allows data export/import via USB when not connected to the network.

• Wiegand Input & Output: Can function as a slave reader when connected to a central controller or as a master in a Master & Slave model.

This feature is especially suitable for two-way access control – users authenticate both upon entry and exit to prevent timekeeping fraud, supporting advanced Anti-passback for enhanced security.

4. Auxiliary Input Interface – Increased Flexibility

A notable advantage of the SF400 is its Auxiliary Input port. The device can connect to:

• Smoke detectors

• Emergency switches

• External security devices

When a signal is triggered, the device can immediately send an alert and activate emergency door opening, ensuring absolute safety in dangerous situations.

5. Rich Features – Meets Diverse Needs

The SF400 integrates a series of smart features, optimizing control and management:

• Scheduled bell: Set automatic bell times for shifts and breaks.

• Direct record query on the device.

• 9-digit user ID: Highly compatible with complex management processes.

• Anti-passback.

• Webserver, ADMS, and printer connection options.

• Supports T9 data entry (like a phone keypad): Easy to operate without software.

6. Detailed Technical Specifications

7. Practical Applications

SF400 is suitable for deployment in:

• Office buildings, companies, showrooms

• Manufacturing plants, industrial zones

• Schools, training centers, hospitals

• Stores, banks, data centers

Especially useful for systems requiring both entry and exit authentication and integration with peripheral alarm devices.
