OSDP vs. Wiegand

Looking to install new access control products or enhance your current security system?

While some access control systems use legacy technology like Wiegand, the most modern, advanced systems are powered by Open Supervised Device Protocol (OSDP) – an access control communications standard developed by the Security Industry Association (SIA) to improve interoperability among access control and security products. Compared to legacy technology, OSDP allows for benefits like increased security and functionality.

In this helpful guide, explore some of the differences between OSDP and Wiegand – and considerations to help you make the best choice for your access control projects.

Compare OSDP vs. Wiegand on these six factors:

• Cybersecurity
• Cost Effectiveness
