DNAKE AC-4D-MW: High-Performance 4-Door Access Controller

In modern enterprise access control architectures, commercial facilities, and multi-door installations, deploying a versatile multi-door controller with robust security protocols and flexible network connectivity is essential. The DNAKE AC-4D-MW is an advanced Linux-based 4-door access control panel engineered for high-density entry points and central management.

Multi-Door Control & Extensive Reader Integration

Designed to manage up to 4 doors and connect up to 8 readers, the AC-4D-MW offers hybrid compatibility for both modern OSDP v2.2 readers and legacy Wiegand devices (supporting 26, 34, and 58-bit formats). It features comprehensive I/O capacity, including 13 inputs (4 exit devices, 4 door contacts, and 5 auxiliary inputs) and 8 outputs (4 lock relays and 4 auxiliary relays), backed by advanced features like multi-door interlocking, anti-passback, and first-person entry logic.

High-Capacity Engine and Flexible Connectivity

Powered by a Linux OS with 256MB RAM and 64MB ROM, the controller supports up to 100,000 users, 300,000 cards, and 300,000 offline event logs. Deployment is made straightforward through dual-band Wi-Fi (2.4 GHz / 5 GHz) and PoE+ (IEEE 802.3at) or DC 12V power supply. It integrates seamlessly into central systems via web interfaces, DNAKE Cloud platforms, or local CMS using standard protocols including OSDP, TCP/IP, UDP, HTTP, and DHCP.

Industrial DIN-Rail Form Factor

Encased in a durable plastic housing measuring 202 x 97 x 57.4 mm, the AC-4D-MW is built for standard DIN-rail mounting inside electrical enclosures. It features onboard status LEDs, buzzer, RTC (real-time clock), tamper alarm, and operates reliably across temperatures from -10°C to +55°C.
