Original product description
This 4-inch embedded facial recognition terminal combines time-attendance functions with indoor access-control hardware.
It is presented for installations such as campuses, offices, factories, ho includes Android, 1 GB RAM, 8 GB storage, a 4-inch display, tempered-glass panel, 2-megapixel wide-dynamic camera, micro ons include RJ45 Ethernet, 2.4 GHz Wi-Fi compliant with IEEE 802.11b/g/n, one USB 2.0 port, a relay switch and a Wiegand interface.
Other listed communication interfaces include RS485, RS232, USB and TCP/IP. Published recognition specifications include a 200–300 ms recognition time, a 0.5–3 m recognition distance and a stated accuracy rate of 99.98%. Liveness detection, voice service and multiple languages are also listed.
Because biometric performance depends on enrollment quality, lighting, installation position and operating conditions, buyers should validate these figures in the intended environment before approving a deployment. The terminal requires a DC 12 V, 3 A input and does not support Power over Ethernet.
It is specified for indoor operation at -25°C to +75°C and 5%–93% RH, non-condensing. OEM/ODM customization and an SDK are offered, with remote installation guidance and online technical support described as available.
Procurement teams should confirm the final display resolution and orientation, since the supplied information lists conflicting resolution values. They should also verify the required face-template capacity: separate entries state 1,200 facial records and support for up to 10,000 face templates.
Before ordering, confirm the exact firmware, attendance software, language package, SDK scope, access-control wiring, Wiegand direction, relay ratings, data export method, server requirements and included mounting accessories.
Buyers should also establish how recognition accuracy and liveness detection will be tested for acceptance, and review privacy, consent, retention and security requirements for biometric data in the deployment jurisdiction.
