ASI3204E-DW is a single door face recognition access controller from Dahua, built for offices, retail stores, and small commercial sites that need reliable biometric access without complex wiring. With built-in Wi-Fi and a genuinely slim profile, this controller is a practical choice for single-door installations that need clean, straightforward deployment.

The ASI3204E-DW supports 1,000 users, 1,000 faces, 3,000 fingerprints, 3,000 cards, and 1,000 passwords, with 50 administrators and up to 100,000 stored records. Face recognition completes in just 0.2 seconds per person with a 99.9% accuracy rate, working across a recognition distance of 0.3m to 1.5m and a height range of 1.2m to 2.0m — genuinely fast even for busy single-door foot traffic.

A 2.4-inch non-touchscreen display with 320 × 240 resolution keeps the interface simple, backed by a 2-MP CMOS HD dual-lens camera with DWDR and auto IR light compensation for reliable image capture across varied lighting conditions. Voice prompts and a built-in speaker provide clear audible confirmation during verification.

Unlock modes on the ASI3204E-DW include card, remote, password, fingerprint, and face unlock, with support for scheduled unlock methods or combined verification for a personalized security level. User types extend to common, VIP, patrol, visitor, blocklist, and two custom categories, giving administrators genuinely flexible control over access permissions.

A standout convenience is the ASI3204E-DW’s built-in Wi-Fi, operating on IEEE802.11b/802.11g/802.11n standards at 2.4 GHz, letting the controller connect without running Ethernet cable to the door — a genuine advantage for retrofit installations. A wired 10/100 Mbps Ethernet port is also included, along with a shared RS-485/Wiegand port for connecting a peripheral card reader.

The ASI3204E-DW includes a built-in doorbell function and a dedicated power output port (12V, 1.0A) that directly powers an electromagnetic lock and card reader — simplifying installation by removing the need for a separate power supply at the door. Security extension modules are supported to help prevent doors from being forcefully opened, adding a genuine layer of physical protection.

Security features are comprehensive: anti-pass back, tamper alarm, duress alarm (including duress fingerprint), door sensor timeout, intrusion detection, and illegal card threshold alerts all work together to protect against common access control vulnerabilities. The device also supports Web attendance management and exporting local attendance reports, letting it double as a basic time attendance solution alongside its access control role.

Genuinely slim at 184.9 x 76.2 x 20.5mm and 0.6kg, the ASI3204E-DW is designed for indoor wall mount installation, with a wall mount bracket included in the box. It draws a maximum of 12W, running on an optional 12VDC, 2A power adapter, and operates across a -10°C to +45°C temperature range.

For single-door installations that need face recognition, flexible backup verification methods, and the convenience of Wi-Fi connectivity plus built-in lock power, the ASI3204E-DW offers a genuinely practical, easy-to-deploy solution.
