ZKTeco SpeedFace M4 Face Recognition Terminal

The ZKTeco SpeedFace M4 is a Linux-based access control and time attendance terminal built around visible-light facial recognition technology. It delivers fast and accurate verification, completing face authentication in under 0.5 seconds even in challenging lighting conditions, thanks to an adjustable brightness supplement light. Alongside facial recognition, the device supports palm, card, and password verification, giving businesses a flexible multi-modal authentication solution.

Advanced anti-spoofing algorithms protect the terminal against unauthorized access attempts using printed photos, videos, or 3D masks. Housed in a rugged metal enclosure rated IP66, the SpeedFace M4 resists dust and water, making it suitable for both indoor and outdoor installation across a wide operating range of -10°C to 50°C.

It stores up to 6,000 face templates, 3,000 palm templates, 10,000 cards, and 200,000 logs, and features a 5-inch touchscreen display. Connectivity options include TCP/IP, RS485, Wiegand, and PoE, with full compatibility with ZKBioAccess, ZKBioTime, and other ZKTeco software platforms. It's an ideal choice for offices, factories, schools, and any facility that needs reliable, high-security access management.
