Border control means more than protecting land borders only. Numerous countries have a large coastline that needs to be protected as well. With over 3,200 kilometres of coastline, Sweden is just one example. 
 
Thermal imaging cameras are a great tool for protecting a country’s land or coastal borders. Although FLIR Systems markets a full range of thermal imaging cameras with cooled detector for these applications, some Original Equipment Manufacturers (OEM) like to incorporate a thermal imaging module in their own product themselves. For these OEMs, FLIR Systems markets a full range of thermal imaging cores that can easily be integrated in any application. 
 
Electro-Optical Surveillance Systems (EOSS) 
 
Based in Sweden, Informationssytem AB is one of Europe’s leading companies for the design and construction of advanced visual surveillance systems for military purposes.“, explains Mr. Fleming Eklund, Manager at Informationssytem AB. 
 
For monitoring a part of the Swedish coastline, we have developed and deployed various ElectroOptical Surveillance Systems (EOSS) for the Swedish Navy and Coastguard. The EOSS have a rugged housing designed for round the clock operation in extreme environments. They withstand the near arctic temperatures of the northern Swedish winters. The housing is mounted on a remote controlled platform.
 
The EOSS are equipped with two daylight cameras. One camera gives full visual coverage of the entire 
surveillance area. The other is equipped with a longrange zoom lens enabling the reading of the name 
of a ship over many kilometres.” 
 
“For night and low light vision purposes, the EOSS is also equipped with a thermal imaging module. We have chosen to integrate the FLIR Systems ThermoVision 3000 core in the EOSS
 
ThermoVision 3000 long range thermal imaging core
 
The ThermoVision 3000 core has been especially designed for Original Equipment Manufacturers (OEM). It can be easily integrated into systems that require an advanced, cooled thermal imaging solution. The module is equipped with a longwave, cooled Quantum Well Infrared Photodetector (QWIP) operating in the 8 – 9 μm waveband. 
 
The ThermoVision 3000 is equipped with triple field of view optics. With the ThermoVision 3000 module, a man-sized target can be detected at over 12 kilometers away, An object the size of a 2.3 x 2.3 meter vessel can be detected at practically 19 kilometres away. 
 
Thermal imaging a great tool inside the EOSS 
 
All these features make the ThermoVision 3000 an excellent module to build into an EOSS that needs to be operational in total darkness as well.”, continues Mr. Eklund. “In Sweden we have quite some dark hours, especially in winter time. Thermal imaging cameras work by making extremely small temperature differences visible. The ThermoVision 3000 core detects differences of no less than 0.03°C. Since there is a small difference in temperature between the main hull of the ship and the lettering on the hull, it is even possible to read the name of the ship in total darkness.”
 
But the thermal imaging core is not only used in darkness. A thermal imaging camera is also not blinded by glare from the sun. Even when its range performance is affected by fog and light rain, it will normally see more than a CCTV camera in these conditions. Therefore the ThermoVision module is used in daylight as well.” 
 
Easy integration
 
Integrating the ThermoVision 3000 in the EOSS was a relatively easy job.”, continues Mr. Eklund. "The ThermoVision 3000 provides a turnkey thermal imager with advanced image processing features built-in and ready for system integration. It incorporates easily with common power and video interfaces found in existing and new systems. The images from the 640 x 480 pixel detectors can be displayed on virtually any existing display that accepts composite video."
 
EOSS monitors the Swedish coastline
 
In order to see as far as possible, the EOSS are positioned on towers more than 20 meters above sea level. They are designed to work in conjunction with a radar in a so-called “slewto-cue” configuration. If the radar is detecting a target, the camera will automatically turn in the right direction so that the operator can see what the blip on the radar screen really means and can begin the identification process. In darkness, the ThermoVision 3000 will do this job seamlessly.”
 
The communication between the cameras and the monitoring station is based on a digital network system. Connection links can be in fiber, coax, or wireless microwave link and require a band width of 8 MBit for real time pictures using MPEG-2 video streaming. All the functions of the EOSS, including the one from the ThermoVision 3000 core, can be controlled from the central monitoring station by a PC with graphic user interface or by a joystick. Any of the central monitoring stations fitted with the interface equipment connected to the digital network can view and control the cameras.”
 
Proven reliability
 
Today, the EOSS are in operation for more than 6 years already.”, explains Mr. Eklund. “No technical 
problems have occurred in this period of time and the Swedish Navy and Coastguard, the endusers of the systems, are still extremely happy. The thermal imaging module inside the EOSS is greatly contributing to this. It assures that no vessel passes the Swedish coastline undetected. Night and day."

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.
