Thermal cameras can often be used to cover larger areas than standard visible light cameras

Smart thermal cameras use on-board video analytics and a high degree of video processing to detect people very accurately in complete darkness, bright sun, and bad weather over the typically large perimeters associated with transportation applications. Combining manpower and smart thermal technology makes security for transportation assets more effective. At the end of the day, it takes people to address active threats; technology, when it provides accurate, reliable information, extends guard force capabilities.

This approach lends itself particularly well to large transportation assets, whether the perimeter of an airport, seaport or rail yard. The same technology can also drive accountability: If an alert is presented and not responded to promptly, it can be escalated to the next level of command, ensuring the effectiveness of the entire security function.

“Often transportation end users rely on guards to secure very large areas under tight budgets,” says John Romanowich, CEO, SightLogix, Inc. “We can make their efforts more comprehensive by augmenting their capabilities with technology to increase awareness about unfolding events that they simply can’t know about otherwise.” For instance, thermal cameras can “see” in the dark and bright sun, in fog, bad weather and detect over very large areas. Greater awareness of unfolding events allows guards to appropriately focus their efforts where they are needed most, at the right time.

SightSensor smart thermal cameras have on-board electronic stabilisation to remove camera shake caused by train, plane or car vibrations, which would otherwise cause nuisance alerts for most video analytics systems. They can also project geo-registered target information onto a site map of the facility so an operator knows exactly where the intrusion is taking place and can respond directly. Using heat to detect intruders, SightSensor cameras solve the biggest problem with past perimeter security systems in the outdoors, which has been high nuisance and false alerts that operators eventually ignore.

For example, the New York State Bridge Authority (NYSBA) uses SightLogix smart thermal cameras to secure five Hudson River bridges, detecting authorized pedestrians, helping manage traffic incidents and securing bridges against vandalism and sabotage. SightSensors operate in all weather. They can detect people and boats in any lighting condition, ignoring car headlights, reflections off water, shadows from clouds, and other movement that would cause alarms for visible light cameras. Geo-referenced video analytics send alarms when a boat lingers too long near bridge pylons or a car breaks down, representing safety hazards.

Bridges are exposed and vulnerable to incidents from all sides. SightSensors use geospatial video analytics to detect intrusions the instant violations occur. By sensing heat rather than visible light, they are a perfect “human detector” in both sun and darkness without additional lighting, and ignore headlights, reflections and movements of small animals, trees or blowing trash while accurately detecting unauthorized persons at great distances.

The system also reduces false alarms with electronic image stabilisation, which removes movement caused by wind and passing cars, a necessity for reducing false positives in a bridge application. According to the NYSBA director, SightSensors provide “a huge return on investment.” For example, securing one area with free access alongside woods could take thousands of feet of chain link fence, outdoor motion sensing devices and surveillance cameras to investigate alarms. SightSensors combine this functionality into a single system, providing cost savings.

ROI for the SightLogix systems comes with the reduction of financial losses; for example, the cost to refurbish a single railroad car following an act of vandalism could be as high as $5,000 to $10,000, along with lost revenue when a car is out of service. Thermal cameras with video analytics improve system ROI by providing highly reliable real-time detection that can be used to avoid incidents or stop an incident in progress.

Thermal cameras can often be used to cover larger areas than standard visible light cameras. Therefore, system camera counts can be reduced, with a resulting lower infrastructure costs to further improve the ROI equation.

What New Technologies And Trends Will Shape Video Analytics?
What New Technologies And Trends Will Shape Video Analytics?

The topic of video analytics has been talked and written about for decades, and yet is still one of the cutting-edge themes in the physical security industry. Some say yesterday’s analytics systems tended to overpromise and underdeliver, and there are still some skeptics. However, newer technologies such as artificial intelligence (AI) are reinvigorating the sector and enabling it to finally live up to its promise. We asked this week’s Expert Panel Roundtable: What new technologies and trends will shape video analytics in 2021?

Tackling The Challenge Of The Growing Cybersecurity Gap
Tackling The Challenge Of The Growing Cybersecurity Gap

The SolarWinds cyberattack of 2020 was cited by security experts as “one of the potentially largest penetrations of Western governments” since the Cold War. This attack put cybersecurity front and center on people’s minds again. Hacking communication protocol The attack targeted the US government and reportedly compromised the treasury and commerce departments and Homeland Security. What’s interesting about the SolarWinds attack is that it was caused by the exploitation of a hacker who injected a backdoor communications protocol.  This means that months ahead of the attack, hackers broke into SolarWinds systems and added malicious code into the company’s software development system. Later on, updates being pushed out included the malicious code, creating a backdoor communication for the hackers to use. Once a body is hacked, access can be gained to many. An explosion of network devices What has made the threat of cyberattacks much more prominent these days has been IT's growth in the last 20 years, notably cheaper and cheaper IoT devices. This has led to an explosion of network devices. IT spending has never really matched the pace of hardware and software growth Compounding this issue is that IT spending has never really matched the pace of hardware and software growth. Inevitably, leading to vulnerabilities, limited IT resources, and an increase in IoT devices get more attention from would-be hackers. Bridging the cybersecurity gap In the author’s view, this is the main reason why the cybersecurity gap is growing. This is because it inevitably boils down to counter-strike versus counter-strike. IT teams plug holes, and hackers find new ones, that is never going to stop. The companies must continue fighting cyber threats by developing new ways of protecting through in-house testing, security best practice sources, and both market and customer leads. End-user awareness One of the key battlegrounds here is the education of end-users. This is an area where the battle is being won at present, in the author’s opinion. End-users awareness of cybersecurity is increasing. It is crucial to educate end-users on what IoT devices are available, how they are configured, how to enable it effectively, and critically, how to use it correctly and safely.

Will Airport Security’s Pandemic Measures Lead To Permanent Changes?
Will Airport Security’s Pandemic Measures Lead To Permanent Changes?

Travel volumes at airports have been increasing of late, although still below the 2.5 million or so passengers the Transportation Security Administration (TSA) screened every day, on average, before the pandemic. As passengers return, they will notice the airport security experience has changed during the pandemic – and many of the changes are likely to continue even longer. Need for touchless technology The lowest U.S. air travel volume in history was recorded last April, with approximately 87,500 passengers. As passenger traffic plummeted, the aviation community sought to explore the potential of new technologies to make security checkpoints more contactless and flexible when the traffic numbers return. The pandemic has seen an increase in touchless technology deployed in the screening area. Used for cabin baggage screening, Computed Tomography (CT) produces high-quality, 3-D images to enable a more thorough analysis of a bag’s contents. Imaging Technology Millimeter-wave body scanners began replacing metal detectors globally as a primary screening method Enhanced Advanced Imaging Technology (eAIT), which uses non-ionizing radio-frequency energy in the millimeter spectrum, safely screens passengers without physical contact for threats such as weapons and explosives, which may be hidden under a passenger’s clothing. Millimeter-wave body scanners began replacing metal detectors globally as a primary screening method.  AI algorithms Other innovations include an automatic screening lane, centralized image processing, and artificial intelligence (AI). Looking ahead, AI algorithms have the ability to clear most passengers and bags automatically, making the process smoother and freeing up staff to focus only on alarms. The pandemic’s need for contactless screening may accelerate the adoption of AI.   CAT machine Credential Authentication Technology (CAT) machines automatically verify identification documents presented by passengers during the screening process. The TSA continues to accept expired Driver’s Licenses and state-issued IDs for up to a year after expiration, based on the premise that license renewals may be delayed and/or more difficult during the pandemic. The REAL ID enforcement deadline was extended to Oct. 1, 2021.  Health precautions Checkpoint health precautions have been a part of the airport screening experience since early in the pandemic. Last summer, the TSA announced the “Stay Healthy. Stay Secure” campaign, which included requirements such as social distancing among travelers, ID verification without physical contact, plastic shielding installed at various locations, and increased cleaning and disinfecting. In January 2021, President Biden signed an Executive Order requiring travelers to wear face masks when in airports and other transportation facilities (to remain in effect until May 11). Checkpoint screening Clear is a privately owned company that provides expedited security that uses biometrics either a person’s eyes or face to speed along the process of getting people through checkpoints. TSA officers wear masks and gloves at checkpoints and may also wear eye protection or clear plastic face shields. The limits on allowable liquids a passenger may take on board were broadened to include a hand sanitizer container of up to 12 ounces, one per passenger in a carry-on bag. a paradigm shift Just as aviation security changed after 9/11, the COVID-19 crisis is expected to lead to a paradigm shift to create a safer and more secure environment. Measures were implemented so that passengers, staff and other stakeholders could have continued assurance and confidence in airports amid and after the pandemic.
