Environmental Resilience

Operating temperature range from -5°C to 45°C accommodates diverse climate conditions, while humidity tolerance up to 80% RH supports installation in coastal and high-moisture environments. The compact form factor (205.20 x 74.19 x 33.30 mm) fits standard electrical gang boxes.

Network Connectivity and Integration

Ethernet and WiFi Options

Standard TCP/IP connectivity through wired Ethernet provides reliable network communication for access control data and video streaming. Optional WiFi capability (IEEE 802.11b/g/n/ax @ 2.4 GHz) enables wireless installation in locations where cable routing is impractical.

Cloud and Software Integration

The SenseFace 2A integrates seamlessly with ZKBio CVAccess software for comprehensive access control management and ZKBio Zlink for cloud-based administration. Mobile app support enables remote monitoring and management through smartphones and tablets.

Protocol Flexibility

Multiple communication protocol support includes AC push, TA push, and BEST protocol compatibility. This flexibility ensures integration with diverse access control software platforms and enables migration between different management systems without hardware replacement.

Access Control Hardware Interface

Electric Lock Control

Integrated relay output controls various electric lock types including magnetic locks, electric strikes, and motorized deadbolts. The system monitors door position through dedicated door sensor inputs, providing complete door status awareness for security management.

Exit Button Integration

Dedicated exit button input supports request-to-exit devices ensuring proper egress compliance. The system distinguishes between authorized exits and security breaches, maintaining detailed transaction logs for audit purposes.

Wireless Doorbell Support

Optional wireless doorbell compatibility (433 MHz) extends functionality beyond traditional access control applications. This feature particularly benefits residential and small office installations requiring visitor notification capabilities.

Data Management and Synchronization

Transaction Storage Capacity

Extensive transaction capacity supporting 150,000 records ensures comprehensive audit trails without frequent data downloads. The system maintains detailed logs including user identification, authentication method, time stamps, and door status information.

USB Data Transfer

USB Type A port enables direct data transfer using standard flash drives formatted to FAT32. This capability supports user data synchronization between multiple devices and provides backup options for critical user databases.

User Capacity Management

The SenseFace 2A supports 3,000 user profiles with multiple authentication credentials per user. This capacity accommodates medium to large organizations while maintaining fast authentication performance across the entire user database.

Installation and Mounting Considerations

Versatile Mounting Options

Wall-mount installation supports both Asian gang box and single gang box configurations, providing flexibility for diverse architectural requirements. The mounting system ensures secure installation while maintaining access to connection terminals and configuration interfaces.

Electrical Requirements

Standard DC 12V 1.5A power supply simplifies electrical installation and reduces infrastructure requirements. Power consumption remains minimal during standby operation while providing adequate power for all integrated functions including video streaming and authentication processing.
