5.6 How to Access the Web Server
The optional Ethernet interface provides some Web Server
& Logger features available via a generic internet browser
such as statistical data of transits and real time status of
each device networked.
Procedure
Access using CEIA Device Discovery utility.
Download
the
CEIA Device Discovery
utility (a .zip
file) at the address
www.ceia.net/swdownload
entering the following data:
program name:
CeiaDeviceDiscovery
, password
(case sensitive):
9iok4ed
Extract the application contained in the .zip file to
the desktop.
No installation procedure is required: simply run the
application
CeiaDeviceDiscovery.exe
.
Select the device within the list provided: the home
page of the device web server will appear.
Alternative access method
If CEIA Device Discovery utility is not available, type
the Metal Detector IP address (default: 192.168.0.1)
or its hostname, in DHCP mode only (default:
‘CEIA-<serial number>‘) in the URL field.
Login.
A login box appears, reporting the Metal
Detector name and the Network Hostname of the
device. Enter a valid programming password of the
WTMD.
Press
SEND
to submit the password: the device status
is acquired and a summary window reporting the Metal
Detector name and the device status appears.
The menu of the available functions is displayed on the
left. Press ‘Help
‘ for detailed information.

5.8 NIJ Standard required information
Operating principle
A
Metal Detector
is a unit that reacts to the metal masses present on
people in transit. The Metal Detector comprises:
- a
control unit CU
, made up of :
- a variable magnetic
field
generator
FG
- a
receiver R
- a
processing and control unit PCU
, which determines if the variation
of the received signal is due to metal masses in transit of a certain shape,
volume or composition
- a
transceiver antenna
A
in the form of an archway, made up of :
- a transmitter part
TX
- a receiver part
RX
- a power supply adapter

Block diagram of a metal detector
As part of the normal screening process, people are required to walk
through the detector archway. A complete analysis requires a complete
passage through the archway.
The equipment is calibrated by maintenance technicians according to the
Security Responsible Authority requirements: therefore, an alarm is given
(by means of various signals) if a person walks through the unit carrying
more metal than the standard amount specified by the Security Responsible
Authority.
Normal quantities of keys, coins, belt buckles and other personal objects
are discriminated and do not give any alarm.
Furthermore, the Metal Detector could also give an alarm signal if people
walk through carrying other sizeable metallic objects, such as cellular
phones, multimedia players.
Summary of the Operating Features
GENERAL FEATURES
20 High Precision localization zones
Chip Card capability for fast, simple, and secure programming
Random alarm capability programmable from 0% to 100%
Continuous self-diagnostic system
No periodic re-calibration and preventive maintenance required
Access to the front panel protected by hardware key and two levels of
passwords
ALARM SIGNALLING
Alarm visual signals
Multi-zone archway LED bar for ‘height on person’
localization; light bars with selectable entry/exit and pacing indication
Green and red metering signals proportional to the mass of the detected
target
Audio signals
10 selectable continuous and pulsed tone plus 34 special
tones; 10 selectable sound intensities ranging from 0 to 90 dbA at 1m
TYPE OF SIGNALLING
Visual
Fixed or proportional to the mass in transit - visible from 6m under
lighting of 4000lux
Visual zone indication
2, 4, 8 or 20 independent zones selectable
PROGRAMMING
Local Programming by Control Unit alphanumeric display and keyboard
Programming and chip card access protected by user and super-user
passwords.
Detector capabilities
The walk-through metal detector is calibrated in order to detect, on people
in transit, metallic objects according to the following classification:
Object Size Classes
NIJ 0601.02 Standard • Large Object Size
NIJ 0601.02 Standard • Medium Object Size
NIJ 0601.02 Standard • Small Object Size
Loss Prevention in industrial/general purpose application.
Other samples as required by the customer.
If the detector is calibrated to the Large Size Object class normal quantities
of keys, coins, belt buckles and other personal objects are discriminated
and do not give any alarm. Furthermore, the walk-through metal detector
could also give an alarm signal if people walk through carrying other
sizeable metallic objects, such as cellular phones, players, pagers or other
noticeable objects.
