We talked today about smart 'access system design', where more than only readers are mounted near openings, but other systems like intercoms and door bells are also installed nearby. Having another method of (requesting) entry is useful when credentials are forgotten, equipment malfunctions, or for visitors seeking entrance.
In my experience as an integrator, there were countless times we installed access readers and locks on a door, only the be called back months later to install some sort of phone or intercom station at the same door. The image below shows an example pairing:
For the designers/installers: how often do you include intercom systems with your access designs?
For everyone: What products or platforms have you used? Any recommendations?
For end-users: would adding intercoms at doors be a benefit, or just an extra cost? What process do you use now to 'let people in' when they have no credential of their own?
