ASI3214A-W is a face recognition access controller from Dahua, built to combine visible light facial recognition with fingerprint, card, and password verification in a single standalone unit. With built-in Wi-Fi and a genuinely fast recognition engine, this controller is well suited for offices, schools, and small commercial sites that need flexible, multi-modal access control without running network cable to every door.
The ASI3214A-W supports 3,000 faces, 5,000 fingerprints, 5,000 cards, and 3,000 passwords, with a substantial 300,000 record capacity for logging access events over time. Face recognition completes in under 0.2 seconds per person with an accuracy rate of 99.9%, working across a face recognition distance of 0.3m to 1.5m and a height range of 1.1m to 2.0m — genuinely fast and reliable even at typical foot-traffic volume.
A 2-MP CMOS HD dual-lens camera with DWDR and auto IR light compensation powers the facial recognition engine, including liveness detection to help distinguish a real person from a photo or video spoofing attempt. The 4.3-inch capacitive touchscreen, with 480 × 272 resolution, gives users a clear, responsive interface for entering passwords or navigating menus, backed by voice prompts for audible confirmation.
Unlock modes on the ASI3214A-W are genuinely flexible: password, fingerprint, card, remote, face, and combination unlock are all supported, letting administrators configure the security level that fits each door or user group. Card support covers both standard IC cards and Desfire EV3 cards, compatible with Dahua cards by default. User types include normal users, VIP users, patrol users, guest users, and blocklist users, giving genuinely granular control over who can access what and when.
Wi-Fi connectivity operates on IEEE802.11b/802.11g/802.11n standards at 2.4 GHz, letting the ASI3214A-W be installed without running Ethernet cable to every door — a genuine convenience for retrofit installations or sites where cabling is impractical. A wired RJ-45 10/100 Mbps port is also included, along with 1 RS-485 and 1 Wiegand port for connecting peripheral card readers.
Security features are comprehensive: anti-pass back, tamper alarm, duress alarm (including duress fingerprint), door sensor timeout, intrusion detection, and illegal card exceeding threshold alerts all work together to protect against common access control vulnerabilities. Remote verification, first user unlock, and restricted/trusted lists round out the administrative toolkit, all configurable through an easy PC or mobile web client.
Compact at 115.0 x 118.0 x 27.1mm and weighing just 250g, the ASI3214A-W supports wall mount, 86 case mount, and desk mount installation, with a wall mount bracket included in the box. It draws a maximum of 18W, running on a 12VDC, 1.5A power adapter, and operates across a -10°C to +40°C indoor temperature range.
For organizations that need genuinely fast, accurate face recognition combined with flexible fingerprint, card, and password backup options — all without mandatory network cabling — the ASI3214A-W delivers a well-rounded, Wi-Fi-enabled access control solution.
