The dream was simple: access control interoperability. You know; the ability to change management software on a whim, or mix together different brands of controllers, yet have everything work together. It is an idea could fundamentally change the access control market.
Especially when ONVIF's Access Profile C was announced, many hoped it marked the start of this dream. Perhaps it would even kickstart the stoic and insular access market in the same way ONVIF has caught fire in surveillance.
Alas, this dream may be over before it really even starts. In this note, we survey the dreadful status of access interoperability and discuss why this is not likely going to change.
