Access Control Door Controllers Guide

By: Brian Rhodes, Published on Oct 22, 2019

Door controllers are at the center of physical access control systems connecting software, readers, and locks.

Despite being buried inside enclosures or hidden inside ceilings, they are a complex component that ties everything else together.

In this note, we examine controllers and their main features including:

  • The three typical forms of controllers
  • The primary function of coordinating access at the door
  • Hardware compatibility across access management software
  • Typical input devices for access, including readers
  • Common types of outputs, including locks
  • IP vs Serial Connected Panels
  • Traditional DC vs. PoE Power
  • Controller features within standalone locks
