OSDP is an open supervised device protocol between access panels and end devices. It is a better communications approach: 

  • bi-directional 
  • more secure 
  • uses fewer wires 
  • longer range 
  • and multi-drop 

It offers unlimited application enhancements such as: 

  • direct biometric support 
  • smart card interface 
  • authentication 
  • FIPS compliance 
  • interactive terminal capabilities 


With an ever-growing list of compatible devices from numerous companies, the OSDP specification was picked up by the Security Industry Association (SIA) in 2012. This valuable specification has now become a valuable industry standard. Please read more about the standard at
