7 key things to know about OSDP Access Control

7 things to know about OSDP

Access Control is evolving continuously like all other technologies. There are several new ways access a building which are better and more affordable then ever.

The most common is a proximity reader with keyfobs or keycards. A growing one for us is Bluetooth Credentials via a Mobile Phone. Simply email the user via the software and they receive a link. The user just clicks, downloads and runs the app in the background and can unlock authorized doors with their Bluetooth signal embedded in their smartphone. 

The signal is then send from the Reader to the Controller for confirmation and then the door is unlocked. The transfer of this signal is largely done via the Wiegand format which goes back to like the 1970’s or older. It works reliably but isn’t the most secure.

That is where OSDP comes into play.

Here are SEVEN key things to know about OSDP Access Control Systems:

  1. It is the true global standard, as approved by SIA (Security Industry Association). 
  2. Its built on RS-485 transmission standard, requiring just 4 conductors (2 less than the Wiegand format).
  3. It facilitates cross functionality and interoperability between various devices and brands. 
  4. Its fully encrypted from reader to controller so it very secure. It utilizes the AES format. That’s pretty important in a security system, don’t you think? 
  5. It’s point to point so everything does not have to be home run back to main location. You can daisy-chain if designed such by the manufacture.
  6. OSDP is more cyber-secured and hardened compared to is predecessor. 
  7. It is truly Bi-directional for better supervision and communication.
