Achieving security awareness around perimeters and outdoor areas
comes down to timely, credible and detailed alerts. Knowing the
nature and location of an intrusion is the key to mounting an effective
response. While there are a number of options available for
perimeter security, thermal cameras with video analytics have become
the fastest-growing technology for perimeter detection. Smart thermal cameras
provide detection over large outdoor areas and operate day or night.
Using smart thermal cameras for perimeter security applications has historically
been seen as a costly solution better suited for government, military or specialized
applications. However, recent developments in thermal camera technology
provide greater accuracy and clearer images at mainstream prices. Thermal video
analytic cameras can now operate in harsh environmental conditions, such as rain,
humidity, fog and bright sun, which in the past yielded poor images, nuisance
alerts and mis-detects. The combination of lower costs and higher performance
is rapidly expanding the market for protecting critical infrastructure assets in the
petroleum, transportation and utility industries, among others.
Petroleum Market
Securing petroleum assets involves a range of requirements. These include protecting
large perimeters, often many miles long; enclaves where public trucking needs to
enter and exit; and isolated assets inside the perimeter where chemicals of interest
(COI) may be stored. In the past, petroleum assets located along water have been
regulated by the Coast Guard Maritime Transportation Security Act. Looking forward,
the Department of Homeland Security will play a role in regulating chemical
facilities under the Chemical Facility Anti-Terrorism Standards (CFATS), a comprehensive
set of security regulations governing chemical facilities.
There is still some debate regarding how water-side assets will be regulated
and when CFATS will be finalized. Assuming that CFATS regulations emerge as
the primary regulating body for petroleum assets, its 18 Risk-Based Performance
Standards (RBPS) represent a helpful guide for chemical facilities to select and
implement appropriate protective measures to reduce vulnerability and manage
risk for the range of requirements mentioned above.
While various technologies can be used to protect chemical facilities, video systems
are playing an increasingly important role in the protection of all outdoor
facilities. Specifically, the CFATS RBPS require chemical facilities to detect intrusions
at the perimeter and internally around COI. This helps to avert internal and
external theft or sabotage, as per RBPS 1, 2, 4 and 10.
A number of automated detection technologies including coax and fiber-fence
sensors, microwave, seismic sensors and radar can provide some level of perimeter
detection. However, intelligent video systems with advanced analytics provide
advantages over these alternatives. One advantage is speed, which is paramount
when thwarting an intruder. The CFATS RBPS specifically call for creating sufficient
time between detection of an attack and potential danger to site assets. When
speed is critical, intelligent video systems can provide an intrusion alert along with
immediate information about the size, location and nature of an event as it unfolds.
On-board image processing enables smart thermal cameras to accurately detect
the presence of unauthorized persons anywhere across site perimeters, enclaves
and isolated outdoor assets while filtering the effects of environmental elements.
Smart cameras with sufficient processing can provide accurate detection over large
areas, regardless of wind, weather or the movement of small animals, trees or
blowing trash.
Achieving security awareness also depends on knowing the precise location and
nature of an intrusion. To meet this objective, some smart thermal cameras employ
GPS-based analytics that determine the size, speed and bearing of detected
objects according to their precise location they also can project the location of
security events onto a site map of the facility for quick response.
Transportation Market
Protecting transportation assets involves covering a wide range of modalities and
industries. Since Sept. 11, 2001, airports have been a particular focus. For all transportation
facilities, now that passenger access points have been secured, more attention
is being paid to the perimeter, the next line of defense against security threats.
In fact, more than 1,300 perimeter security incursions have been reported at U.S.
airports since 9/11, making airport perimeter security an important concern.
Airports of all sizes have a critical need to detect people or vehicles moving
from the public side toward the runways. This was made very evident with the March 1 incident when a vehicle broke
through perimeter fencing and drove
onto the runways at Philadelphia International
Airport, creating a threat and
endangering the lives of passengers on
approaching aircrafts.
The TSA Airport Perimeter Security
(APS) projects work to assess and mitigate
vulnerabilities through technology.
TSA also funds the National Safe Skies
Alliance, a third-party, nonprofit testing
organization that evaluates technology
with potential for security applications
at airports. TSA evaluators conduct numerous
test scenarios to determine the
effectiveness of various perimeter security
systems. The tests are designed to
simulate a human intruder attempting
to defeat a system by breaching the perimeter
detection zone without causing
an alarm. The scenarios are tested in
multiple areas throughout an airport’s
perimeter.
A recent TSA test at Buffalo Niagara
International Airport, the busiest airport
in upstate New York, highlighted
the value of smart surveillance systems.
The test showed that it is possible to ensure
accuracy, even in an uncontrolled
environment with constant changes in
lighting, wind, clouds and other variables,
and to provide effective outdoor
security that isn’t plagued by nuisance
alarms and mis-detects. The perimeter
of the Buffalo Niagara airport is a difficult
environment, with varying topology
and inconsistent illumination, but
the application challenges are similar to
many airport perimeters.
TSA’s APS project deployed a smart
thermal camera system by SightLogix
Inc. at the Buffalo airport as a test bed
for future perimeter security technologies.
According to TSA’s final report,
the “evaluation team performed more
than 900 scenarios in which every alarm
instance was accurately reported.”
The system included Thermal
SightSensor video analytic cameras for
detecting and tracking intrusions over
large areas and SightTracker PTZ controllers
to automatically steer Pelco
cameras to zoom and follow detected
targets. Fixed Thermal SightSensors
were installed to protect critical regions
of the perimeter and to provide
automated monitoring to detect people
or vehicles moving from the public
side toward the runway. Cameras were
positioned to provide additional surveillance
across multiple access gates
and portions of the perimeter that are
adjacent to public roadways. Video
and alarm data was networked to a
central monitoring station via fiberoptic
cable.
A system like this can deliver cost
savings—savings that also are applicable
to a range of transportation markets
and other applications. On-board
image processing offers extended detection
capabilities, reducing the number
of poles, trenching and communications
needed for a deployment, while
exceeding the automated detection area
originally specified in the design. The
result at Buffalo airport was a more accurate
perimeter security system that
met the airport’s available budget. The TSA testing emphasizes the
DHS concern in this particular area,
and the results show that these technologies
are now proven for widespread
developments at other airports and
transportation facilities.
Electrical Market
Electrical facilities and other utilities
often have a need to protect geographically
distributed sites that are typically
smaller than petroleum and transportation
facilities. Protection of electrical
assets involves detecting a wide range
of intruders, from saboteurs to copper
thieves, often in different weather conditions.
Intrusions onto the sites can be
expensive: Replacing equipment can
cost hundreds of thousands of dollars,
although the value of stolen copper
might be only a few hundred dollars.
Also related to electrical utilities,
protection of hydroelectric sites involves
a need to view intruders as they
approach a dam, for example, and requires
a smart video system that can
provide reliable surveillance despite the
challenges of flowing water.
Distributed sites often call for securing
multiple locations with a single
smart camera—or dozens of cameras—
at each site. The use of thermal
analytic cameras at electrical utility
sites demonstrates the flexibility of intelligent
video systems. These robust
and dependable systems are designed
to achieve the highest levels of detection
accuracy at the lowest overall
project cost.
Mainstream Applications
Web-based tools can simplify system
design and enable integrators to quickly
and easily model an automated outdoor
area and perimeter security system
layout. Using a design tool enables
systems integrators and consultants to
walk end users interactively through
the process of system design for their
facility. Simplified integration facilitates
the evaluation and adoption of
these technologies in mainstream markets.
SightLogix offers a Web-based
tool for efficient security designs using
the Google Maps interface.
Combining better thermal images
with edge-based video analytics yields
accurate and dependable outdoor
security at mainstream price points.
Enhanced image processing enables
new thermal cameras to adapt to dynamic
outdoor conditions and provide
good, clear images, day or night, that
are close in quality to black-and-white
photographs.
New systems that provide twice the
detection distance and four times the
detection area with greater detection
accuracy can have a major impact on
return-on-investment considerations
about perimeter security systems.
Smart thermal cameras for protecting
critical assets also offer the advantage
of greater security
at lower operating
costs.
