SpeedFace-V4L is a Linux-based hybrid-biometric access control and time and attendance terminal from ZKTeco, featuring visible light facial recognition and palm recognition in one compact device. Built for organizations that want strong biometric security without the cost of a flagship terminal, the SpeedFace-V4L combines face, palm, card, and password verification methods.

The SpeedFace-V4L’s anti-spoofing algorithm is genuinely comprehensive, guarding against print attacks (laser, color, and black-and-white photos), video attacks, and 3D mask attacks — a broader coverage than many terminals in its class offer. Facial recognition speed is rated at ≤1 second, keeping check-in queues moving smoothly.

A 4-inch touch screen delivers a clear, responsive interface, powered by a 900MHz dual-core CPU with 512MB RAM and 512MB Flash storage, running on Linux. A 2MP binocular camera with adjustable LED supplement lighting powers the facial recognition engine, using ZKFace V5.8 and ZKPalm V12.0 algorithms for reliable dual-biometric verification.

The SpeedFace-V4L supports 1,000 face templates (optional 2,000), 1,000 palm templates, and 1,000 cards (optional 2,000), with a substantial transaction capacity of 150,000. Card compatibility covers 125kHz ID card (EM) as standard, with optional support for 13.56MHz IC card, HID card, and Felica card, giving installers flexibility to match existing credential infrastructure.

Communication is genuinely comprehensive: TCP/IP, USB Host, optional WiFi, Wiegand input and output, and RS485 are all supported, giving administrators flexibility for networked deployment or integration with existing access control panels. Standard functions include ADMS, T9 Input, DST, Camera, 9-digit User ID, Access Levels, Groups, Holidays, Anti-passback, Record Query, Tamper Switch Alarm, and Palm Recognition.

The SpeedFace-V4L includes an access control interface supporting 3rd-party electric lock, door sensor, exit button, alarm output, and auxiliary input, letting it function as a standalone access control device. Optional functions extend to SRB Function and a cable box, giving installers further flexibility depending on the specific deployment.

Compact at 72.94 x 157.94 x 23mm (W×H×D) and weighing just 260g net (850g gross), the SpeedFace-V4L runs on a 12V, 3A power supply and operates across a 0°C to 45°C temperature range with 10%-90% humidity tolerance. It’s supported by ZKBio Access IVS software. For organizations that need genuinely broad anti-spoofing protection combined with dual face and palm biometric verification in a compact, cost-conscious terminal, the SpeedFace-V4L delivers a well-rounded security solution.
