| LG's IrisAccess 3000, a system entirely developed by
LG Electronics, was introduced in the fall of 2001. It's
a multi-component system that includes: |
|
 |
 |
|
 |
| Usually
found in an HR or security control location,
the EOU3000 (connected to a server/database)
is placed on a desk or table and used
in a supervised enrollment environment;
the enrollment subject is in a seated
position. It contains all the elements
necessary to initiate the enrollment
process, illuminate the iris and acquire
an iris image. In addition, it provides
voice prompts and messages and as well
as visual cues that indicate when the
enrollment process has been completed.

| The
ROU3000 is installed adjacent to a door
where access control is desired. The
unit is composed of two + -parts - the
optical imager with the front and rear
enclosure. After the rear enclosure
is mounted to, or recessed within the
wall adjacent to the controlled portal,
the optical imager with the front enclosure
is mounted within the rear enclosure
to provide a double layer of security.
ROU3000 contains the elements for iris
image acquisition, and provides audio
and visual cues that indicate whether
or not the user is authenticated. Mounted
at the recommended height of 57"
from the floor, the ROU comfortably
accommodates a wide range of short or
tall users. |

 |
| The
ICU3000 is always installed on the wall
inside the protected or controlled area.
Unlike many other biometric devices
including some other iris recognition
cameras, no biometric templates are
stored on the optical unit. Iris images
input via the ROU3000 reach the securely
located ICU3000 which creates 512-byte
templates from ROU input to compare
these with stored values. If a match
is found, the unit generates a signal
to directly open a door, or provides
Weigand output to signal a panel that
then controls access. An ICU 3000 with
one Frame Grabber Board (FGB) and one
Door Interface Board (DIB) controls
two doors. Inserting another FGB and
DIB increases the number of ROUs/doors
an ICU3000 can control to four. |

 |
| The
Frame Grabber Board captures analog
black and white iris images. It converts
the analog iris image into the digitized
format to process in the Server, ServerPC
or ICU3000. |

|
 |
| The
Door Interface Board checks and controls
the releasing and the locking of a portal
associated with a particular ROU. The
Door Interface Board also provides the
interface between ROU3000 and the Mother
Board in an ICU3000. Used standalone,
the DIB can activate a portal. The Door
Interface Board also provides standard
Wiegand or RS422 output for use with
a panel or reader environment. |

| System
enrollment, monitoring and management
can be handled in a variety of ways.
These roles can be performed by one
PC or PCs working in concert. In an
enterprise system, all these functions
can be assumed by a larger host unit.
