ZKTeco SF300 Fingerprint Time Attendance and Access Control

ZKTeco SF300 is a professional IP-based fingerprint access control and time attendance terminal engineered for comprehensive security management in commercial and industrial environments. This compact biometric terminal combines advanced fingerprint recognition technology with network connectivity, enabling seamless integration into existing security infrastructure while supporting both standalone and networked operation modes.

How the SF300 Access Control System Works

The SF300 utilizes ZKTeco’s proprietary optical fingerprint sensor operating at 500DPI resolution with ZKFinger VX10.0 algorithm for accurate biometric identification. The terminal connects to networks via TCP/IP or RS485 communication protocols, synchronizing with ZKAccess3.5 software for centralized access control and time attendance management across multiple locations.

Dual Operation Modes

• Network Mode: Real-time communication with centralized management software for immediate data synchronization and remote monitoring
• Standalone Mode: Independent operation with local data storage, ideal for locations with limited network infrastructure
• Master-Slave Configuration: Two SF300 units can be linked using Wiegand input/output for enhanced security requiring verification at both entry and exit points

Biometric and Card Recognition Capabilities

The SF300 incorporates multi-modal authentication supporting both fingerprint biometrics and proximity card technologies. With storage capacity for 1,500 fingerprint templates and 5,000 card credentials (EM/Mifare compatible), the system accommodates diverse user populations while maintaining rapid identification response times.

Advanced Security Features

The SF300 implements up to 15 different verification methods to establish appropriate security levels for various access zones. The anti-passback function prevents unauthorized credential sharing by tracking user entry and exit patterns, while the duress alarm feature provides silent emergency alerts when users are coerced to provide access under threat.

Emergency Integration and Safety Systems

Emergency response capabilities distinguish the SF300 from standard access terminals. The auxiliary input interface enables connection with external safety devices including smoke detectors, emergency switches, or panic buttons. When the linkage function is activated through the device menu, the SF300 automatically generates alarm signals and unlocks doors during emergency situations, ensuring occupant safety compliance.

Time and Schedule Management

The integrated scheduling system supports up to 24 user-defined time schedules with optional daily bell alerts for shift management or facility announcements. Standard access control features include customizable time zones, holiday schedules, access control groups, and unlock combination settings that provide granular control over user permissions and facility access patterns.

Technical Specifications and Installation

The SF300 measures 105 x 105 x 34mm with a compact form factor designed for standard 86mm wall socket installation. The 2.8-inch resistive touch screen displays a graphical user interface with multi-language customization options, while the tamper-proof switch and multiple alarm outputs ensure physical security of the terminal itself.

Network and Power Requirements

• Communication: TCP/IP, RS485, and USB Host connectivity options
• Power Supply: DC 12V/3A with stable power requirements
• Operating Conditions: 0°C to 45°C temperature range with 20-80% humidity tolerance
• Data Storage: 80,000 transaction record capacity for comprehensive audit trails

Software Integration and Management

ZKAccess3.5 software provides comprehensive management capabilities for the SF300, enabling administrators to configure user permissions, generate attendance reports, and monitor real-time access events across multiple terminals. The system supports offline data management through USB flash drive connectivity, ensuring data accessibility even during network disruptions.

Frequently Asked Questions

What card types are compatible with the SF300?

The SF300 supports both EM (125kHz) and Mifare (13.56MHz) proximity cards and can store up to 5,000 card credentials alongside fingerprint templates for flexible authentication options.

Can the SF300 operate without network connectivity?

Yes, the SF300 functions effectively in standalone mode, storing all transactions locally with capacity for 80,000 records. Data can be retrieved via USB flash drive or synchronized when network connectivity is restored.

How many fingerprints can the SF300 store?

The SF300 can store up to 1,500 fingerprint templates using ZKTeco’s advanced ZKFinger VX10.0 algorithm, providing fast and accurate biometric identification for medium to large user populations.

What emergency features does the SF300 include?

The auxiliary input allows integration with smoke detectors, emergency switches, or panic buttons. During emergencies, the SF300 can automatically unlock doors and trigger alarm notifications to ensure safe evacuation procedures.
