A New Generation of Detectors
Ranger’s new generation of Intelliscan
high security walk-through detectors
set a new standard in performance.
Their detection characteristics are
superior and they are easier to set up
and operate. New data processing
hardware and software programs
improve their interference rejection, dis-
crimination, sensitivity, detection unifor-
mity, vibration tolerance and orientation
response. Their increased discrimina-
tion significantly reduces unwanted
alarms.
They include Horizontal Axis Gain
Control (HAGC) and an optional
Detection Enhancement feature.
HAGC helps correct detection non-uni-
formity caused by vertically positioned
external metal. Detection
Enhancement is an optimization pro-
gram that allows the user to create
customized security programs.
To accommodate wheelchair access,
frames with inner widths up to 36 inch-
es (914 mm) are now available.
The Multi-Zone Advantage
In addition to showing the location of
targeted objects, multi-zone detection
increases other aspects of screening
efficiency. It improves discrimination
between weapons and harmless
objects, reduces unwanted alarms and
permits higher traffic flow rates. In high
traffic locations, this translates into
lower operating and capital costs. It
reduces the number of detectors, per-
sonnel and amount of real-estate need-
ed per given number of people
screened.
Better Discrimination Through Multi-
Zone Detection
False alarms are attributable to exter-
nal electrical and electro-magnetic
interference and poor tolerance to
vibration. Good quality interference
rejection and mechanical design lowers
false alarms.
Multi-zone detectors reduce unwanted
alarms caused by harmless personal
effects such as keys, coins, jewelry,
belt buckles, shoe shanks, cigarette
packs, etc. In handgun screening
applications multi-zone detectors elimi-
nate the need for most people to empty
their pockets of keys and coins.
Two conditions contribute to high
unwanted alarm rates; cumulative sig-
nal effect and non-uniform detection.
Cumulative signal effect lowers a
detector's ability to separate weapons
from harmless personal effects. It
occurs when signals generated by
metal items that are carried or worn,
are processed as a single composite
