Description

The professional Dahua proximity reader is an advanced device dedicated to access control systems, combining modern aesthetics with the highest resistance to weather conditions. This model has been designed for operation in the most demanding environments, which is confirmed by the high IP67 ingress protection rating. As a result, the device is completely protected against dust ingress and the effects of short-term immersion in water, making it an ideal choice for outdoor installation on buildings, fencing posts, or at entrance gates.

Specification

The device supports the Mifare (13.56 MHz) standard, which ensures a high level of security and a stable card and key fob reading range between 1 and 9 cm. The reader is characterized by exceptional versatility due to its support for two popular communication interfaces: RS-485 and Wiegand. This allows for easy integration with a wide range of access controllers from various manufacturers. Additionally, the built-in Watchdog module ensures the continuity of the device's operation, automatically restarting the system if errors are detected, which minimizes the risk of the terminal hanging.

The physical security of the reader is provided by an integrated tamper output, which immediately notifies the system of any attempt to unauthorizedly open the housing or tear the device from the mounting surface. The user is informed about the access status by means of clear visual signaling in the form of red and green LEDs and audible signals generated by the built-in buzzer. The compact and slim housing, made of high-quality black plastic, perfectly complements modern architecture, ensuring the installation is both discreet and elegant.
