What is Wireless Wiegand for?

Introduction

The Wireless Wiegand kit is an innovative solution designed to streamline the communication between access control systems and their peripheral devices via radio transmission, using LowRange (LoRa) technology. This kit comprises a master and a slave device, eliminating the need for extensive physical wiring and enabling a more flexible and scalable deployment.

Purpose of the Wireless Wiegand Kit

The primary function of the Wireless Wiegand kit is to replace traditional wired connections between an access control board (Master device) and its peripherals (Slave device) with a wireless communication system. This is particularly advantageous in environments where laying cables is impractical or too costly.

Operational Mechanism

  1. Initial Interaction: A user presents an access card to the reader connected to the Slave device.
  2. Data Transmission: The reader captures the card code and sends it to the Slave device, which then transmits it wirelessly to the Master device.
  3. Processing and Execution: The Master relays this information to the control board, which processes the data and, if the access is authorized, activates the necessary relays to unlock the door.
  4. Relay Activation: The relay state is communicated from the control board back to the Master device. The Master Device then sends this state to the Slave device, which activates its own relay to control the lock, effectively unlocking the door as authorized.
  5. Feedback Loop: Changes in the state of the door (open or closed) are detected by sensors connected to the Slave device. This information is transmitted back to the Master device and then to the control board for logging and event management, ensuring that every state change is accurately recorded and monitored.

Benefits

  • Reduced Installation Complexity: Significantly lowers the logistical burden and cost associated with physical wiring.
  • Enhanced Flexibility: Facilitates easy installation and reconfiguration of access control systems in complex environments.
  • Reliable Communication: Utilizes LoRa technology to ensure secure and reliable long-range communication between devices.

Conclusion

The Wireless Wiegand kit is an essential development in access control technology, offering a robust, scalable, and cost-effective solution for managing entry and exit in various settings without the constraints of physical wiring. This system is ideal for large campuses, historical buildings, or any location where physical alterations are limited.
