What is Wiegand Access Control?
Wiegand access control is a system that uses magnetic fields to transfer data from a credential, such as a key card or fob, to a reader. Weigand technology has become a cornerstone in access control systems.
How Does Wiegand Access Control Work:
Wiegand access control system comprises several key components:
- Credentials: These are typically key cards, fobs, or badges embedded with Wiegand wire. Additionally, each credential contains unique data encoded during manufacturing.
- Reader: The Wiegand reader includes a coil that generates a magnetic field. When a credential comes into proximity, the magnetic field induces the Wiegand wire to release energy. Consequently, the reader captures and decodes this burst of energy.
- Control Panel: This is the system’s brain. When the reader captures data from a credential, it sends the information to the control panel. Then, the control panel verifies it against the stored database.
- Door or Gate Lock: Upon verification, the control panel sends a signal to the locking mechanism. Consequently, the door or gate opens.
Why Wiegand Access Control is Safe to Use:
- Wiegand credentials store data in a hard-coded format, making them difficult to clone or tamper with.
- Having been in use for several decades, Wiegand technology has a long track record of reliability and security.
- Advanced integration makes Wiegand systems highly compatible with various other access control technologies.
- Wiegand credentials are known for their durability and long lifespan.
- Minimal Maintenance: Once installed, Wiegand systems require minimal maintenance.
Considering Alternatives:
- Durability and Reliability: Barrier gates are built to withstand harsh weather and heavy usage. Additionally, RFID cards and readers are durable and reliable, ensuring consistent performance over time.
- Cost-Effective Solution: Although the initial setup of barrier gates and RFID technology requires an investment, it is cost-effective long-term. Moreover, it reduces the need for physical security personnel and minimizes the risk of human error in access control.
- Scalability: The combination of barrier gates and RFID technology is scalable, suitable for any installation size. Additionally, RFID cards or readers can be easily added as needed.
- User-Friendly: RFID technology is convenient for authorized personnel. Additionally, it eliminates the need for physical keys or access codes, which can be easily lost or shared.
