HID Global has two product lines. The newer product line is called EVO, and the older
one is called Legacy. There are two product families in each product line: VertX and Edge.
Products from different families cannot mix. Security
Center supports them all.
About HID controllers
The Access Manager communicates directly with HID
controllers over an IP network. Therefore, all HID controllers are called access control
units in Security
Center.

Limitations
On a Card and PIN door controlled by an HID Edge EVO
unit, if a host lookup is necessary (an unknown credential is entered and the unit must query
the Access Manager before making a decision), the cardholder must wait a few seconds after
presenting their card, before entering their PIN. Entering the PIN too quickly might result in
a denied access because the first few digits of the PIN might not have been registered by the
unit.
