Add Receivers

  • Read here for more information on how to add receivers, add / edit schedules, and, add / edit call lists

Once a receiver is added then the intercom will be ready to begin making calls.

Types of I/Os

Verkada Intercom allows for various types of input and output devices to be attached and interface with it. The I/O port allows for two inputs and one output to be attached to it.


The input is a set of two dry contacts that watch for NO or NC from the device attached to the input I/Os.

Call Trigger

Any input that sends a close signal to the Intercom can be used as a call trigger. For example, if PIR motion sensor was used then the Intercom would make a call when the motion sensor is triggered.

DPI (Door Position Indicator)

Any contact that sends an open or close signal. Typically DPI's are contacts that are contained within or on a door and used to determine if the door is physically open or closed.

REX (Request to Exit)

When a close signal is made then the Intercom will unlock the door that is paired to it. For example a REX could be a standard button or PIR motion sensor.


The output is a dry relay with ports for NO, COM, and, NC. The output can be used to trigger a door unlock.

Door Unlock

Upon door unlock the dry relay triggers and sends a close or open signal to the device attached to it. If the door unlock is going to be used to trigger the lock or unlock of an electrified lock then it is required that proper external power supplied or power controllers are in place in order to operate the lock.


Intercom output can be used to set a chime.
