Introduction to the EF-45 Iris Recognition System
The EF-45 iris recognition system offers highly intuitive, hands-free iris biometrics
imaging in a compact and elegantly designed identification and authentication
terminal for use in a wide range of identity management applications.
The front facing nominal 5.0inch LCD serves to display
the user’s face image for fast, easy and highly natural
positioning for proper iris image capture. The subject
merely puts his or her face in the positioning box at the
top of the LCD, and then moves toward the system to
size his or her head to the box to be in proper range.
Image capture is fast and automatic. While user
instructions are very simple, almost all subjects will be
able to interact with the system without any direction.
The capture range is a robust 35 to 45 cm, also contributing to the system’s ease of
use. There is an optional “fast capture mode”, in which the range is further extended to
30 to 45 cm, although in this mode, images may not conform to ISO 19794-6 2011 or
ISO 29794-6 standards.
And the internal automatic tilt mechanism adjusts to the user’s height or vertical
position over a range of 40 cm (about 16 inches), making the EF-45 ideal for wall
mount, countertop, desktop, or kiosk installations.
The EF-45 is an embedded terminal, which means that all image processing and
machine control is performed on the internal Linux-on-ARM mainboard. Typical
connectivity to host systems is through TCP/IP (Ethernet). And iris biometric encoding
and matching is typically performed on-board as well, so identification or
authentication decisions can be made locally for fast responsiveness. For access
control, there are Wiegand connections for dedicated, local communications to door
controllers or panels.
Other options include WiFi and extended on-board data base (to 40,000 users), and a
smart card reader (in the AC version).
For all specifications, please see Specifications section.
TW EF-45™ Next
Generation Iris
Recognition System

Key Features
•Intuitive LCD face display positioning for fast, simple and natural iris user experience—similar
to face display facial recognition systems.
•Contactless iris imaging at range of 35 to 45 cm stand-off in normal mode, and 30 to 45 in
fast recognition mode. (Note: enrollment is always performed in normal mode.)
•Internal, automatic face and iris camera tilt mechanism with nominal height range of 40 cm
•Positioning guidance vocalizations selectable on / off and delay time. English is standard; all
other supported languages are available with .wav file substitution
•Simultaneous dual iris recognition with typical capture speed of under 1 second
•On-board iris encoding and matching, with internal data base of up to 10,000 users in either
1:1 (verification) or 1:N (identification) modes. Option for 40,000 users with match speed of
1.0 second in 1:N mode.
•Face Recognition and Combined Face and Iris modes:
Supplemental face recognition in case of iris recognition failure-to-capture (FTC) in
enrollment. Face recognition is used as primary modality in authentication for specific
individuals.
•Supports dual factor authentication with card or PIN
•Optimized imaging for difficult ambient lighting conditions
•Optimized image capture for most sunglasses, glasses, and facial veils
•Supports imaging of all iris colors
•Kensington lock slot standard
•Standard communications connectors and protocols for TCP/IP (Ethernet RJ-45), RS-485 and -
232, dual Wiegand I/O, TTL, and dry contact relay
•Connection cables with press-in connectors included in accessories kit
•External audio connector
•Tamper switch on rear panel
•Access control (AC) configuration includes wall mount plate
•Optional WiFi support (USB dongle module)
•Integrated Smart Card reader (MiFare / DesFire card)
•Meets CE mark, FCC, IEC 62471 eye safety, and RoHS standards. Iris recognition meets ISO
19794-6 2011 and ISO 29794-6 standards. (Certifications available on request.)
•Design and production processes meet ISO:9001 2008 standard.

Mounting Instructions
Recommended mounting height and UI (left), Capture Volume of EF-45 (right)
The recommended mounting height for the EF-45 is 144 cm (57 inches) from floor to
the bottom of EF-45. The mounting height can be adjusted to accommodate the
height of the average user.
High ambient light and / or direct light into the EF-45 should be avoided. Sunlight,
halogen lamps or other strong illumination may reduce the performance of the EF-45
and may result in increased failure-to-capture rates or failed authentication events.
The EF-45 was designed for indoor use only. This unit is not weatherproof and must
not be exposed to water, ice, extreme temperatures or other adverse weather
conditions. If it is required to use this unit in outdoor or extreme environments,
Note: Installation in extreme environments without proper protection may cause
permanent damage and void warranty.

User Interface for Iris Image Capture
1) Position yourself facing
straight at the LCD display.
When the device detects your
movement within 1.0meter
range, it initiates the image
capture sequence. A
rectangular-shaped user guide
box will appear on the screen.
If it is BLUE, it means you are
too far from the device. Move
forward.
2) Move towards the system to
size your face to the LCD
display. If the user guide box
flashes GREEN, it means you
are at an appropriate position.
Stop and hold your position
until the device captures
image of your face and/or iris.
3) If you are standing too close
to the device, your face will
not fit in the LCD display.
When the user guide box
flashes RED, it means the
device cannot capture your
image because you are too
close. Move back until the box
turns green.
EF-45 captures the images of subject’s irises and face automatically.

On-board Demonstration Application
The on-board demonstration application shows the full capabilities of the EF-45 for image
capture including subject positioning with the face display user interface, enrollment, and
on-board matching (authentication).
The system boots up in this demo application. It is initated by the video based motion
detector that first finds the subject from about 1 meter distance, and then continues the
natural iris image capture sequence for capture in recognition / authentication mode.
To switch to enrollment mode, press large User icon in center of main Launcher page. If
the system is in image capture mode, press Home icon ( ) on top left of active user
interface display, which will stop Recognition mode and return system to Launcher page.

The following main User screen appears:
This user screen also allows simple database management. By tapping the Delete icon
in the bottom right, one can easily delete information of enrolled users.
To enroll a new user, press the Enroll icon to bring up Enroll User screen.
Press the plus (+) button in the bottom left to capture image of the new user.

An instruction screen will appear for 3 to 5 seconds, and then switch to the user
interface. (The timing of this display can be changed in Settings.)
After successfully capturing iris images, click on √OK to accept images. The system
then returns to Enroll User screen. Click on Name field to enter name of subject, then
click on √OK to complete enrollment.
Press the Home icon ( ) to return to the Launcher page to re-start Recognition and
Authentication mode.
