PREFACE
Iris Reader BM-ET330E is used in an access control system. The iris reader, which captures a user's iris image, is available for
following uses.
• As an enrollment iris reader for iris image capturing and iris server enrollment
To activate iris recognition, it is necessary to capture the iris images of a user and enroll the iris data in the iris server.
An iris reader generates iris data from iris images captured, and transfers the data to the iris server in the LAN (Local Area
Network). The iris data is enrolled in the iris database of the iris server. Up to 5 025 users can enroll their iris data. *

For iris data enrollment, you need to install the optional Administration Software BM-ES330E. The PC needs to have
Microsoft

Windows
®
operating system installed.
The total number of users that can be enrolled differs depending on the total licence numbers of the User Licence Software
BM-EU30000E Series.
• As a recognition iris reader for iris recognition
Iris data of up to 1 000 users can be distributed from the iris server to iris readers. If the iris data of user has been distrib-
uted to a recognition iris reader, or if a card reader (connected to a recognition iris reader) reads the iris data out of a card,
the iris reader can recognize the user in approx. 1.5 seconds. *

The user can check the recognition result with the result
indicator (ACCEPT/REJECT) on the front panel of the iris reader.

The recognition time may differ
depending on capturing condi-
tions.

The iris reader captures the iris
images of both eyes at the
same time, but the iris data of
each eye is enrolled separately.
Enrollment/recognition by one
eye capturing is also available.

Up to 256 iris readers (enrollment and recognition iris readers) can be connected to the iris server in the LAN.
• Iris recognition technology is a way to identify a person with iris patterns (an iris is
the thin plate-shaped film in front of the eyeball), which differ among each person.
The iris pattern of the left eye differs from that of the right eye.
• Using iris readers, users can carry out recognition without touching any devices.
• In the iris recognition process, the users are recognized with the enrolled iris data.

(1) Captures the iris images of both eyes.
(2) Recognizes a user by checking the iris
images with the iris data (that is distributed
to the iris reader or that is read out by the

If no corresponding iris data
has been found in
the iris reader, the iris reader
accesses the administration
