OSDP module


The Open Supervised Device Protocol, or OSDP, is an access control communication standard developed by the Security Industry Association (SIA) to improve interoperability amongst access control products, whilst providing increased security.

Benefits of OSDP

Compared to many existing legacy protocols, OSDP offers:

  • Higher security with up to AES-128 encryption between the reader and controller, as well as constant monitoring of the wiring to protect against attack threats.
  • Advanced functionality such as bi-directional communication to configure readers through the software.
  • Reduced cost as installation requires only 2 wires, instead of 12+ and, due to the simplicity of installation, there’s less time on site.
  • Greater interoperability between different devices and solutions, as a globally accredited open standard
  • An unique feature of Impro’s OSDP module is the support of both Wiegand and OSDP, to enable a simplified upgrade path.
