Critical infrastructure facilities that must secure large areas with extended outer boundary and numerous entry points, present a particularly difficult challenge when it comes to perimeter protection. As such, true end-to-end perimeter protection calls for the utilization of a sophisticated, multi-layered solution that is capable of defending against anticipated threats. Integrated systems that incorporate thermal imaging, visible cameras, radar and strong command and control software are crucial for covering the various potential areas of attacks. Let’s look at these technologies and the five key functions they enable to achieve an end-to-end solution that provides intrusion detection, assessment and defense for the perimeter. 1. Threat Recognition The first step in effectively defending against a threat is recognizing that it’s there. By combining state-of-the-art intrusion detection technologies, facilities can arm themselves with a head start against possible intruders. An exceptionally important aspect of effective perimeter protection is the ability to conduct 24-hour surveillance, regardless of weather conditions, environmental settings, or time of day. Visible cameras do not perform as well in low light scenarios and inclement weather conditions. However, thermal imaging cameras can provide constant protection against potential intruders, regardless of visual limitations, light source or many environmental factors. In fact, facilities such as power stations located near bodies of water can use thermal cameras to create what is known as a “thermal virtual fence” in areas where they are unable to utilize the protection of a physical fence or wall. Deterring suspicious activity can be achieved through real-time two-way audio, a simple but powerful tool Critical infrastructure applications require not only continuous video surveillance and monitoring, but also a solution that yields highly reliable intrusion detection, with fewer false alarms. This need makes advanced video analytics a must for any adequate surveillance system. Features like dynamic event detection and simplified data presentation are game changing in supporting accurate intrusion analysis and facilitating a proactive response. Advanced analytics will provide multiple automated alarm notification options, including email, edge image storage, digital outputs or video management software (VMS) alarms. Incorporating high quality, unique and adaptive analytics can virtually eliminate false alarms, allowing security personnel to respond more efficiently and effectively, while also lowering overall cost for the end user. While surveillance technologies such as radar, thermal imaging and visible cameras, or video analytics work well on their own, utilizing all of these options together provides an advanced perimeter detection system. For example, ground surveillance radar can detect possible threats beyond the fence line as they approach and send a signal to pan-tilt-zoom (PTZ) cameras, triggering them to slew to a specific location. From there, embedded analytics and visible cameras can further identify objects, notify authorized staff, and collect additional evidence through facial recognition or high-quality photos. 2. Automatic Response Systems Once an intrusion attempt is discovered, it is important to act fast. Organizing a response system that can initiate actions based on GPS location data, such as the slewing of PTZ cameras, automated intruder tracking or activated lighting sensors, greatly increases staff’s situational awareness while easing their workload. For instance, thermal imagers deployed in conjunction with video analytics can be used to generate an initial alarm event, which can then trigger a sequence of other security equipment and notifications for personnel to eventually respond to. Having all of this in place essentially lays the entire situation out in a way that allows responders to accurately understand and evaluate a scene. Power stations located near bodies of water can use thermal cameras to create a “thermal virtual fence” in areas where they are unable to utilize the protection of a physical fence or wall 3. Deterring Suspicious Activity After the designated auto-response mechanisms have activated and done their job, it is time for responders to acknowledge and assess the situation. From here, authorized personnel can take the next appropriate step toward defending against and delaying the threat. Deterring suspicious activity can be achieved through real-time two-way audio, a simple but powerful tool. Often, control room operators can diffuse a situation by speaking over an intercom, telling the trespasser that they are being watched and that the authorities have been notified. This tactic, known as ‘talk down’, also allows officers to view the intruder’s reaction to their commands and evaluate what they feel the best next step is. If individuals do not respond in a desired manner, it may be time to take more serious action and dispatch a patrolman to the area. 4. Delay, Defend, Dispatch And Handle The possible danger has been identified, recognized and evaluated. Now it is time to effectively defend against current attacks and slow down both cyber and physical perpetrators’ prospective efforts. Through the use of a well-designed, open platform VMS, security monitors can manage edge devices and other complementary intrusion detection and response technologies, including acoustic sensors, video analytics, access control and radio dispatch. A robust VMS also enables operators to control functions such as video replay, geographical information systems tracking, email alerts and hand-off to law enforcement. With the right combination of technologies, facilities can take monitoring and evidence collection to the next level The primary purpose of the delay facet of the overall perimeter protection strategy is to stall an attempted intrusion long enough for responders to act. Access control systems play a key role in realizing this objective. When a security officer sees a non-compliant, suspicious individual on the camera feed, the officer can lock all possible exits to trap them in one area all through the VMS. 5. Intelligence: Collect Evidence And Debrief More data and intelligence collected from an event equals more crucial evidence for crime resolution and valuable insight for protecting against future incidents. With the right combination of technologies, facilities can take monitoring and evidence collection to the next level. One innovative resource that has become available is a live streaming application that can be uploaded to smart phones and used for off-site surveillance. This app gives personnel the power to follow intruders with live video anywhere and allows operators to monitor alarm video in real-time. Geographic Information System (GIS) maps are computer systems utilized for capturing, storing, reviewing, and displaying location related data. Capable of displaying various types of data on one map, this system enables users to see, analyze, easily and efficiently. Multi-sensor cameras, possessing both visible and thermal capabilities, provide high-contrast imaging for superb analytic detection (in any light) and High Definition video for evidence such as facial ID or license plate capture. Integrating these two, usually separated, camera types into one helps to fill any gaps that either may normally have. Still, in order to capture and store all of this valuable information and more, a robust, VMS is required. Recorded video, still images and audio clips serve as valuable evidence in the event that a trial must take place to press charges. Control room operators can use data collection tools within their VMS to safely transfer video evidence from the field to the courtroom with just a few clicks of their mouse. More advanced video management systems can go a step further and package this data with other pertinent evidence to create a comprehensive report to help ensure conviction.
In the physical security space, video analytics have historically over-promised and under-delivered, often leaving end users sceptical about their capabilities. However, increased integration with security solutions and other business systems, as well as developments in deep learning and artificial intelligence (AI), have given video analytics a significant boost in recent years. Here, we take a look at the key trends putting video analytics in the spotlight, and how this opens up new opportunities for increased security and business intelligence. Deep Learning And AI Will Enhance Video Analytics Capabilities At the start of 2018, our security industry experts commented on how deep learning technology and Artificial Intelligence (AI) would extend to the video surveillance industry, allowing security professionals to gain very specific insights into human behaviour. Our experts predicted that this would permit organizations to reduce risk, enable efficiencies, reduce costs, ensure compliance and provide faster access to stored video. With AI-enables video systems, video analytics are set to perform more complex applications at a higher level of accuracy. Image Processing Developments Allow Intelligent Analytics According to Ambarella’s Chris Day, advancing chip technology combined with the neural network approach to computer vision is game changing for video analytics. Since the problem of higher resolution has already been solved, the key differentior for video surveillance systems will be the ability to add computer vision in parallel with image processing and high-resolution encoding – ideally in a chip that is low-power. Integration With Security Systems Increases Video Analytics Value Video systems produce an immense amount of data that is often wasted, says Bosch Security Systems’ Sean Murphy. When video analytics alerts are integrated with other security systems, video events can trigger responses from other parts of the security solution. For example, cameras with video analytics can initiate intrusion detection system events initiate intrusion detection system events, prompting the panel to take action by alerting the central station or sending video to security personnel. Video Analytics Add Value With Actionable Business Intelligence Adding network video to the current generation of Internet of Things (IoT) solutions provides actional value beyond situational intelligence for security purposes. With increasingly intelligent sensors, interactions between business systems are becoming more sophisticated, providing a value greater than the sum of the parts. Organizations can use smart applications to reduce energy consumption, allocate workspace, and reduce operating costs. In a retail environment, analytics are now capable of assessing a scene for occupancy and crowd control, even generating reports of trends over time. Video Analytics Detect Abnormalities To Predict Incidents Camera-based video analytics can go beyond assessing a current scene to predicting potential risks before they occur, explains Pelco’s Jonathan Lewitt. Based on predetermined factors or analysis of prior events, systems can collect all available information to determine the level of severity of a situation and whether an action needs to be taken. At the same time, systems can correlate data from video and other sources to help analyse similar occurrences in the future. Video Analytics Increasingly Supplemented With Audio Analytics Audio analytics are often overlooked, notes Hanwha Techwin’s Paul Kong, perhaps due to differing privacy laws from video surveillance. However, audio analytics processed in a camera can help provide a secondary layer of verification for events, as well as identifying gunshots, screams, or other sounds indicating an incident is taking place. This makes audio analytics ideal for dealing with active shooter events at schools and campuses. As Louroe Electronics’ Richard Brent explains, audio analytics software can detect rising levels of human aggression, as well as recognising firearm discharge. This can trigger alerts to ensure incidents are dealt with swiftly.
According to IHS Market, it is estimated that there are over 60 million security cameras in the United States, and other reports say these cameras capture more than four billion hours of footage per week. Over the last decade, IP camera technology has dominated the conversation as it has provided users with a broad offering of enhanced image quality and features. With a large percentage of existing security systems relying on analog, many end users looking for high definition (HD) video quality have been forced to take on a complete system overhaul. Infrastructure Overhaul For HD Video To make the switch, customers would need to change everything, from cameras to hardware to wiring– not to mention the lengthy installation process that would ensue. IP cameras also require higher Internet speeds and more cloud space. Whether constrained by budget, bandwidth or storage, many end users have been unable to adopt this new video surveillance method.Thanks to technological advancements within the security industry, HD over Coax offers a viable solution for integrators and end users alike Thanks to technological advancements within the security industry, HD over Coax offers a viable solution for integrators and end users alike. By utilising the current Coaxial cables, this offering yields high definition video, while requiring minimal infrastructure changes and is an optimal surveillance choice for security customers. Plus, with new advancements and updates being made frequently to this technology, there is a solution for every security need. The enhanced alternative of HD over Coax has been warmly welcomed in the security industry, thanks to its simple solutions and ever-evolving features. Many new analog HD cameras are “plug and play,” able to connect directly to existing Coaxial cables. This eliminates the need for a complete system change, creating cost-savings for the end user and an enhanced video quality offering. Easy Solutions For HD Video As a result, integrators can cost-effectively upgrade their customer’s surveillance solution while using their legacy infrastructure, making it an attractive option for end users and an easy sell for dealers. Latency in video is another common issue with network-based camera systems, where even the slightest delay in video surveillance can hinder security response HD over Coax cameras themselves are always expanding and evolving to meet a wide array of security needs. With the introduction of fisheye and multi-sensor cameras, users now have a multitude of coverage options, not to mention the introduction of 4K bringing resolution options to the same level as IP. Some newer technologies are even touting 4K cameras paired with 4K digital video recorders (DVRs) made specifically for analog systems. Longer cables grant transmission for up to 1600 feet, double the distance of standard analog solutions, and triple that of IP systems. This single cable is able to transmit both HD video and audio. Recently, broadcast quality audio over Coax has become available in limited models, a substantial improvement over older analog technology, which was unable to transmit audio. Stopping Video Delay Latency in video is another common issue with network-based camera systems. Even the slightest delay in video surveillance can hinder security response. IP cameras are forced to compress and packetize their video for transmission. The outcome of this is a reduced number of images per video, which in turn causes delay. HD over Coax on the other hand, delivers an unlimited amount of HD images in real time, with smooth motion and impressive clarity. Additionally, the point-to-point transmission delivers uncompressed video free of lag. Another touted benefit is that, unlike IP networked cameras, analog systems provide a more secure video transmission. With so much sensitive information housed on a businesses’ network, adding another point of network access through an IP camera can create concerns for cyber security risks. HD over Coax delivers an unlimited amount of HD images in real time, with smooth motion and impressive clarity Preventing Network Hacking With HD over Coax, the physical connections between the camera and DVR prevent network hacking. By keeping the video surveillance system offline, security professionals are able to direct their attention to the physical threats at hand, rather than having to focus on deterring cyber security risks. One of the primary difficulties of deploying HD video solutions is the fact that many older systems utilize a wide variety of HD standards and platforms. To make matters more complicated, after HD over Coax was brought to market, manufacturers raced to create their own version of this technology. Today, the most popular proprietary standards are HD-CVI, HD-TVI and AHD. However, integrators and customers found that attempting to manage multiple HD technologies proved to be near impossible.Integrators and customers found that attempting to manage multiple HD technologies proved to be near impossible Diversifying Surveillance Through One DVR To combat these issues, manufacturers have introduced products with more flexibility to their portfolios. One example of this is the penta-brid DVR which grants the ability to seamlessly integrate multiple technologies deployed across one application. This means that systems with diverse camera brands and technologies, such as a mix of HD-CVI, HD-TVI, AHD, analog or IP, can be connected through one DVR. For many end users with legacy analog systems, penta-brid DVRs give them greater freedom to choose between a variety of solutions, rather than being limited to one option. With video resolution increasing, the space needed to store the footage is similarly rising. Penta-brid technology has been able to adapt to these evolving needs, giving users ample storage space to house the HD and 4K surveillance video with some of the newest models including H.265 compression. HD Casino Surveillance Made Simple For casinos, HD images are critical for identifying unauthorized personnel and unlawful behaviours to create a safe environment for guests and staff While HD over Coax is beneficial to many end users and integrators, those in the casino and hospitality markets find it crucial. With a combination of high profile guests, large amounts of cash on hand, constant crowds and strict industry regulations, reliable video surveillance is a must. Deploying new IP systems comes at a stiff price. When looking to upgrade their video surveillance, casinos must also be mindful of the installation process. When moving to an IP-based system, ripping out old wires and replacing them with new is the standard practice. This practice can be both disruptive and costly, not to mention gaming regulations require casino activities be monitored at all times so a complete system shutdown would result in revenue loss. This cost can be hard to justify, especially when the current legacy analog system remains in working condition with only the lower image resolution to date it. For these scenarios, the most cost-effective option is to leverage the legacy infrastructure, replace the existing cameras with new devices, and reap the benefits that HD video has to offer without any lapse in security. For casinos, HD images are critical for identifying unauthorized personnel and unlawful behaviours to create a safe environment for guests and staff. HD over Coax cameras now offer the same resolution as IP cameras with a plug and play approach, that cuts down on expense without sacrificing quality. For businesses and applications that are unable to adopt IP technology, whether it be cost or time prohibitive, HD over Coax now features most of the same benefits IP has to offer without breaking the bank. By providing clear images in real time, maximizing existing infrastructure, and affording cyber security benefits, HD over Coax provides an attractive solution for many end users and integrators.
Intelligent solutions, such as those derived from artificial intelligence, help critical infrastructure organizations make sense of vast amounts of data. These integrated applications, such as advanced video analytics and facial recognition, can automatically pinpoint potential breaches and significant events, and send alerts to the appropriate personnel, departments, and agencies. These solutions can be powerful in unifying disparate command center technologies, fusing critical data input from emergency calls and responder activity to enhance situational awareness. Electrical substations are particularly vulnerable (and in need of extra security) due to their role in power distribution and the nature of their equipment. The challenge power utilities worldwide are facing is finding an affordable solution, which can help detect, deter and facilitate an informed response to a substation security event. Data capture form to appear here! U.S. regulations In the United States, this need is furthered by the physical security mandate CIP-014 issued by the North American Electric Reliability Corporation (NERC), calling for identification of security issues, vulnerability assessments and deployment of appropriate processes and systems to address. CIP-014 identification of security issues, vulnerability assessments and deployment of appropriate processes and systems to address CIP-104 specifically calls for implemented security plans that include measures to deter, detect, delay, assess, communicate, coordinate and respond to potential physical threats and vulnerabilities. Manufacturers of video and other systems are designing products to serve the critical infrastructure market. For example, Dahua Technology offers explosion-proof cameras with a combination of rugged reliability and superior optics that is a fit for surveillance of explosive and corrosive environments, including chemical plants, refineries, and other facilities in the oil and gas industry. This explosion-proof series of cameras are housed in enclosures that are certified to the ATEX and IECEx standards for equipment in explosive atmospheres. Each explosion-proof camera features Dahua’s Starlight technology for ultra low-light sensitivity and high-definition sensors that deliver clear images in real-time. They are IP68-rated to prevent water and dust ingress. Each explosion-proof camera features Dahua’s Starlight technology for ultra low-light sensitivity and high-definition sensors that deliver clear images in real-time Video footage in extreme temperatures Another manufacturer, Videotec, offers a range of cameras and housings that provide video footage regardless of aggressive external factors, such as ice cold, scorching heat, desert sand, the force of sea or wind, total darkness, pollution, corrosion and even explosive agents. SightSensor thermal systems enable a utility to detect and respond to substation security incidents across multiple sitesSightLogix smart thermal camera systems have been deployed to protect substations for electric utilities and other critical infrastructure facilities. SightSensor thermal systems enable a utility to detect and respond to substation security incidents across multiple sites, ranging from copper theft to vandalism while also meeting regulatory compliance. At each substation facility, Thermal SightSensors are positioned along the perimeter, and are paired with a high-resolution pan-tilt-zoom camera for alarm assessment. When a Thermal SightSensor detects an intruder, the target’s location information is sent over the network to a SightTracker PTZ controller, which automatically zooms and steers PTZ cameras to follow the intruder. The target’s location is also displayed on a topology site map to provide real-time situational awareness. Alarms are sent to the utility’s 24-hour security operations center, which will contact law enforcement in real time when unauthorized intrusions are detected. Integrated intrusion detection and lighting systems The Senstar LM100 hybrid perimeter intrusion detection and intelligent lighting system is simplifying security at one U.S. electrical utility company. For years, the utility company had integrated its perimeter intrusion detection and lighting systems. The company has now installed the Senstar LM100 which provides detection and lighting in one product and saves them over $80,000 per site. The savings are a result of the reduction of electrical requirements, conduit, grounding, and associated labor, as well as the removal of certain equipment from project scope that are required for the two-system integration. The Senstar LM100’s perimeter LED-based lighting acts as an initial deterrent. If an intruder persists and an attempt to cut, climb or otherwise break through the fence is detected, the closest luminaire begins to strobe, and an alert is sent via a security management system. The intruder knows immediately they have been detected and that their exact location is known by security and others in the vicinity.

Thermal cameras see heat rather than light, so they are a perfect “human detector” Safeguarding outdoor assets in a reliable and cost-effective manner often comes down to a single requirement: Accurate intruder alerts and timely information about the unfolding event. While there are many technologies available for outdoor security, smart cameras with video analytics have emerged as the solution of choice for detecting intruders in real time outdoors. Yet the best technology will be handicapped if the alerts generated cannot be trusted. Repeated false alarms can eventually condition security operators to ignore real intrusions, undermining trust in the perimeter security system. High Accuracy With Low False Alerts In most cases the short-sighted response is to single out the security force as scapegoats, which ignores the real problem: alert fatigue. After responding to hundreds of perimeter breach alarms that turn out to be nothing more than small animals or windblown branches, even the most conscientious security guards lose confidence in the system and start to ignore its warnings. There is no longer any reason for this situation to exist. By following best practices of product selection and deployment, it is now possible to use video security cameras to protect outdoor assets with high accuracy and low nuisance alerts. As costs continue to fall, many organizations are now able to choose thermal cameras as the foundation for their outdoor detection applications Smart Thermal Cameras Viable outdoor security must start with a sensing system that is accurate, 24-hours per day. For this reason, conventional wisdom asserts that smart thermal cameras are the best system for detecting intruders outdoors. This is because thermal cameras see heat rather than light, so they are a perfect “human detector,” and will ignore headlights, reflections off water, and other light-based activity, expanding their usefulness from their traditional role as night vision cameras to 24-hour intrusion detection solutions. Smart thermal cameras with built-in Video Analytic software offers several advantages: They detect in the dark with no need for costly artificial lighting They work 24 hours/day They ignore reflections, shadows, moving headlights, direct sunlight, and other light-based phenomena that can trigger alarms in a visible camera detection system Because humans give off heat, thermal sensors are far more effective in spotting a person than visible cameras They detect body heat of intruders over large areas In the past, the higher price for thermal technology limited their use in commercial applications, but as costs continue to fall, many organizations are now able to choose thermal cameras as the foundation for their outdoor detection applications. A smart camera needs to ignore the animal while alerting on distant person, even though the animal will cover more of the camera’s field of view Accurate Detection With Geo-Registration Smart thermal cameras are designed to detect movement, but outdoors, everything moves. A smart camera must be able to tell the difference between small objects such as leaves or debris and a person entering a secured area. One of the best ways for a camera to make this determination is through “geo-registration” which enables a three-dimensional capability. Geo-registration is a critical technology for accurate video analytic size rules that increase accuracy and reduce false alerts. Consider how human vision works: Our eyes give us depth perception – we can tell which object is close and which is far. But a “one-eyed” camera can’t, unless it’s geo-registered. For example, a small animal near the camera will look much larger than a man at 300 meters away. A smart camera needs to ignore the animal while alerting on distant person, even though the animal will cover more of the camera’s field of view. Eliminate Camera Movement With Stabilisation Many intrusion detection systems are deployed along open areas that are naturally impacted by high winds or vibrations from planes, trains, weather and machinery. Without image stabilisation, these applications can be overwhelmed by nuisance alarms or worse, outright misdetects. It is difficult for smart cameras to detect movement in a scene when the whole field of view is also moving from camera shake. The best way to overcome the impact from wind or vibrations is to choose smart cameras that stabilise the image electronically, before the video analytic rules are applied. Look for cameras that use electronic or gyro-based stabilisers as a foundation for their detection capabilities. Outdoor On-Board Video Analytics Cameras which employ both a high degree of image processing and on-board video analytics have a great advantage in accuracy and detection distance over solutions that employ analytics on a server, outside of the camera. Cameras without embedded analytics must compress the video data for transmission over the network. That’s a problem because compression removes most of the finer scene details—up to 99% of the original data—seriously degrading a video analytic system’s ability to accurately detect and recognize targets. In fact, on days with restricted visibility due to rain or fog, data compression has caused smart cameras to miss virtually all intruders in a scene. On the other hand, when the uncompressed imagery is processed by video analytic software directly in the camera, 100% of the raw scene data is available for analysis. With on-board image processors examining the full visual detail of every video frame, you can achieve a much greater degree of accuracy in detecting motion and recognizing potential threats. With on-board image processors examining the full visual detail of every video frame, you can achieve a much greater degree of accuracy Increasing Probability Of Detection Smart thermal cameras are a great way to protect outdoor assets. But the system has little value if people can enter a secured area undetected. Here are some pointers to avoid gaps in coverage and make sure your system detects every time. A perimeter security system based on video analytics operates by “seeing” targets that move into a camera’s detection area. Knowing the camera’s true range lets you design a dependable system with no coverage gaps. Unfortunately, some manufacturers specify camera ranges that overstate their detection capabilities. This means it’s up to the integrator to determine the camera’s true detection distances. Otherwise your perimeter solution may leave gaping holes that can allow intruders to pass through undetected. Determining True Detection Range The best practice to determine a camera's true detection range is to measure the farthest distance at which the camera can automatically detect a person walking “inbound” or directly toward the camera. Inbound detection is always less than crossfield because a person moving across the camera's field of view creates a larger amount of motion, which is easier to detect. In contrast, a person walking toward the camera produces very little motion, making the target more difficult to detect. In the real world, intruders can enter a perimeter from any direction, so it’s important to design the system for all situations. For complete coverage, the view of each camera must be designed to cover the adjacent camera’s blind spot Addressing Blind SpotsA camera’s field of view doesn’t begin where it’s mounted. Instead it can only detect at a measurable distance in front—this is the blind spot. Every security camera has a blind spot, and this must be considered in the perimeter security design, or someone will be able to walk right under a camera undetected. To provide complete coverage, the view of each camera must be designed to cover the adjacent camera’s blind spot. Perimeter Design Software Some manufacturers offer design tools that can help you model a camera layout using a Google map of the area under consideration. This is a good practice to check detection distances ahead of time and ensure that blind spots are properly addressed. SightLogix offers such a tool, called SightSurvey. Smart Video Solution Today’s smart video is an ideal solution to the new challenges in site protection that confront security professionals. It outperforms older technologies by a wide margin. It often costs less. Installation is less disruptive, and the technology is highly reliable. Essentially, a smart video security system is a force multiplier, taking the burden of monotonous surveillance off regular security staff. Instead of just watching endless video feeds, the staff gets information that lets them do their jobs better. When deployed using best practices of product selection and installation, smart thermal video is the obvious choice for outdoor site security applications.
