Perimeter Intrusion Detection
ground, microwave, passive and active
infrared, and video motion sensors could
have possible airport applications. Most
of these are recognised technologies that
are available as commercial off-the-shelf
products. But the unique demands of an
airport environment provide certain chal-
lenges to detection, even for the most tried
and trusted perimeter security systems.
This is the purpose of the test facility - to
assess the technologies’ performance when
exposed to typical airport environmental
pressures.
The Perimeter Security Test Facility is
designed to adapt to almost any type of
perimeter intrusion detection device and
configuration. Presently, Safe Skies is
testing a series of four cable-type fence-
mounted devices, but many other perimeter
protection systems will be considered for
evaluation. Ample space is available for
installing volumetric sensors, such as
microwave or infrared technologies, and the
8-foot galvanised steel chain-link fence will
support different types of fence-mounted
line sensors. Even buried cable technologies
will be considered, if the demand arises.
The individual vendors are responsible for
installing and calibrating their own devices
at the test facility. Once a manufacturer’s
technician confirms that the device is ready
for testing and that the equipment is cor-
rectly interfaced with the electrical and data
collection hardware, Safe Skies commences
its testing cycle and vendor input is limited
to only severe maintenance issues.
Safe Skies’ testing methodology for the
perimeter devices entails a comprehensive
schedule of attempt-to-defeat scenarios
and unattended false and nuisance alarm
data collection. Every device tested has a
specific test plan that considers its unique
attributes and capabilities, yet all devices
are evaluated in conjunction with similar
technologies of the same type. For example,
the four devices currently installed at the
facility are mounted on the same fence, and
thus are subjected to identical and concur-
rent tests. The alarm results, however, are
collected separately and will be compiled
in individual reports for each device. This
approach allows Safe Skies to test multiple
devices simultaneously, saving time and
funds, but gives the TSA an individualised
report on the performance of each system.
