Dahau Access Controller Two communication protocols: RS-485

Description

The Dahua Access Controller with two communication protocols, including RS-485, is a device that manages and controls access to a secured area or door. The two communication protocols likely include:

1. RS-485: A serial communication standard for long-distance communication over twisted-pair cables.
2. Another protocol (e.g., TCP/IP, USB, or Wiegand): This could be a secondary protocol for communication with other devices or systems.

This access controller likely supports various features, such as:

– Access control and management
– Door control and monitoring
– User authentication (e.g., card, password, or biometric)
– Event logging and reporting
– Integration with other security systems (e.g., video surveillance, intrusion detection)

The RS-485 protocol allows for reliable and long-distance communication, making it suitable for large-scale access control installations. The second protocol provides flexibility and compatibility with various devices and systems.

This access controller is suitable for various applications, including:

– Security and surveillance systems
– Commercial and industrial buildings
– Government and institutional facilities
– Public spaces (e.g., airports, stadiums)
– High-security environments (e.g., data centers, banks)
