ZKTeco SpeedFace-V4L Pro Facial Recognition Access Control Terminal
The ZKTeco SpeedFace-V4L Pro is a standalone biometric access control device engineered for fast, secure, and contactless identification. Combining facial recognition with fingerprint authentication and optional palm and RFID verification, it delivers a flexible solution for modern access environments. With integrated WiFi, advanced anti-spoofing algorithms, and support for mask detection, the unit is well suited for offices, industrial sites, and high-traffic public facilities. Its compact form factor and responsive 4 inch touch display simplify deployment while maintaining enterprise-grade performance.
The SpeedFace-V4L Pro provides a multi-layered biometric authentication platform designed to improve security and operational efficiency. It integrates facial recognition, fingerprint scanning, and optional palm and card verification into a single device, reducing reliance on physical credentials. The built-in 2MP binocular camera ensures accurate recognition even in dynamic environments, while anti-spoofing technology mitigates risks from photos or video attacks. With support for video intercom, mobile app integration, and dynamic QR access via ZKBio platforms, it enables seamless communication and remote management. Its IP65-rated housing, fast verification speeds, and flexible connectivity options make it a practical choice for both indoor and semi-outdoor installations.
Advanced Biometric Access and Security
The device leverages intelligent facial recognition algorithms alongside computer vision technology to deliver rapid and accurate identification. Recognition speeds are optimized for real-time access control, with facial verification typically completed in under 0.35 seconds. The system supports multiple authentication combinations, allowing administrators to configure access rules based on security requirements.
Anti-spoofing functionality enhances system integrity by detecting fraudulent attempts using images or recorded media. This ensures consistent reliability in environments where identity verification is critical.
Integrated Video Intercom and Smart Connectivity
A notable capability of the SpeedFace-V4L Pro is its built-in video intercom functionality. Equipped with a microphone and speaker, it supports two-way communication directly from the terminal.
Two deployment approaches are available:
The system also supports dynamic QR code access through ZKBio Zexus, extending its usability to visitor management and time attendance scenarios.
Display, Hardware, and System Architecture
The device is built around a Linux-based platform with efficient hardware resources to ensure stable operation. Its 4 inch TFT color touch screen provides a clear and responsive user interface, while the in-glass fingerprint sensor enhances durability and accuracy.
