Access control reader Dahua ASI1201M-MEP — Ethernet 10/100 Mbps, 12V 1.5A, 18W, Grey

Dahua ASI1201M-MEP is an access control reader designed for reliable door entry management in offices, residential complexes and commercial sites. The compact grey unit supports Ethernet 10/100 Mbps and common network protocols including IPv4, IPv6, TCP, UDP and P2P, and can be powered via 12 V DC or PoE. Its metal front housing with plastic rear, mechanical backlit keypad and integrated card reader enable combined authentication methods while offering protection against environmental and mechanical stress.

Advantages

The reader supports large user databases and logging, with capacity for up to 10,000 users, 10,000 passwords, 10,000 cards and 100,000 records, making it suitable for medium and large installations. It provides multiple communication interfaces (Ethernet, RS-485, Wiegand) and flexible connectivity options including DHCP, auto registration and P2P. Built-in features such as buzzer, indicator light, doorbell support and multiple alarm types (tamper, duress, intrusion, unlock timeout and card abuse) enhance security and operational feedback. IP65 and IK08 ratings ensure durability in exposed locations, while web-based configuration and compatibility with SmartPSS lite, DSS PRO and DMSS simplify setup and management.

How to use

Mount the reader using surface-mount hardware in a position adjacent to the door at an appropriate height for users. Connect to the local network via Ethernet and configure IP settings via DHCP or static addressing, or use P2P/auto registration for cloud-based setup. Supply power via a 12 V DC source with at least 1.5 A capacity or use PoE if available. Integrate the reader with the door control system using Wiegand or RS-485 connections as required, and configure user credentials, access levels and alarm parameters through the device web interface or compatible management software.

Usage recommendations

For reliable operation, install the reader where it is protected from direct extreme weather and where the mounting surface is solid. Use PoE where possible to simplify cabling and provide centralised power management. Regularly back up configuration and event logs and apply online firmware updates through the supported management platforms to maintain security and compatibility.
