SSN has a video interview with Ron Virden, current ACRE COO, former Lenel President:
Most of the 20-minute discussion is about the demand for using mobile phones for access control, noting strongest draw for this being for new companies (without existing infrastructure), with millennials (and millennial decision makers) plus the potential for increasing access control usage on interior doors (helped in the future by mobile phone usage).
What do you think of his thoughts?
