Delta Scientific DSC7500 swing beam barricade is designed to close off one or two lanes of a roadway and provide counter terrorist level protection against vehicle attack and has been tested in the United Kingdom to stop a 7,500 kg (16,500 pound) 2-axle European truck traveling 80 kph (50 mph), meeting the BSI standard PAS:68 2007, which tests barricades to a standard most similar to the U.S. State Department’s K12 rating. "The DSC7500 uses its latest in crash beam technology," relates Delta Scientific Senior Vice President David Dickinson. "This swing beam barrier has been tested and certified in both the United Kingdom and the United States to stop truck bomb attackers dead in their tracks right at the barricade. The DSC7500 is being used worldwide, primarily at locations where roadways need to be secured from attacking vehicles." The DSC7500 is supplied as an easy to use manual gate or powered with full automation features. Other versions of the DSC7500 Series include a full swing gate with anti-climb features that can replace existing non-rated swing gates. Delta's beam barricades are available in hydraulic and manually operated models. All models are crash rated with one version enhanced for applications at nuclear power plants. Their clear openings range is from 3.2 m to 9.0 m (10.5 to 29.5 feet).

Public spaces in cities and suburbs are important places for community development and promoting outdoor recreation. These areas may include main streets, parks, promenades, band shells and fields. Such locations are often utilised by public event planners for community activities, including summer festivals, wintertime ice skating rink installations, music concerts and art fairs. As the year drew to a close, holiday and Christmas markets as well as major New Year’s Eve events, presented cities with constant public event security needs. The public nature of these events increases risks of incidents with high-speed vehicles that put attendees in danger. Fortunately, there are three ways for public space managers to prevent casualty-causing collisions and further promote the use of local public areas. Developing an effective action plan When strategising how to react to an alert, think about what time of the year and time of day the event is occurring It is important to have a plan developed before an incident or accident occurs. Warning systems, utilising doppler radar and digital loop technologies, alert guards to abnormal vehicle velocity changes in the surrounding area. Managers of public areas should organise a meeting with public safety authorities and local agencies to discuss what must immediately occur when a high-speed vehicle is approaching a public event. When strategising how to react to an alert, think about what time of the year and time of day the event is occurring. Having such a reaction plan in place combines technology and strategic planning to ensure everyone is on the same page to effectively target a threat and promote overall event safety. Securing public areas Ideally, there will be no need to implement a well-conceived action plan. After all, taking preventive measures to secure public areas where events take place is important to keep people safe from accidental vehicle collisions and intentional attacks. Protect attendees by clearly separating pedestrian and vehicle locations using security devices such as – Barricades Portable barriers Bollards Install guard booths Avoid the risk of vandalism and theft, making sure people are safe when walking back to the cars at night by keeping parking areas illuminated with flood lights. Install guard booths with employees who monitor activity in the parking area and who are prepared to react if an alert is triggered. Furthermore, prevent accidental collisions by clearly marking the parking area with informative warning signs and using barricades to direct traffic. These three tips can be used by public area managers to promote security at the next community event. Additionally, the technologies used to secure an event can also be used as infrastructure for year-round security. Installing gates that shut when the public space is closed or using aesthetically pleasing bollards are steps any public area manager can take to promote community safety.
As anyone who has ever flown on a commercial airline since 2001 knows, security measures at airports are well enforced and the emphasis on traveller safety is all around the airport and its grounds. Mass transportation, meanwhile, presents a special but not any less significant challenge when it comes to determining security issues. These facilities need to develop the means to protect a constantly changing and large population of passengers. And unlike airports these facilities often have hundreds of points of entry and exit on multiple modes—buses, subways, light rail, commuter trains, even ferries. About 2 million Americans will use the nation’s airways on a given work day, while 35 million people will board some form of public transportation. In fact, statistics have shown that nearly 11 billion trips are taken on public transportation every year. In some large metropolitan areas in North America where mass transit is well established, more than 20 percent of the area’s inhabitants get around via public transportation.About 2 million Americans will use the nation’s airways on a given work day, while 35 million people will board some form of public transportation Solving mass transit security For transportation officials and their security providers, solving the mass transit security issue begins with determining the key concerns and then creating the proper responses via security systems, policies and procedures to mitigate the risks. Although vandalism and graffiti are very visible signs of criminal behaviour in mass transit settings such as bus stops and subway stations, this is not where transportation officials typically focus their energy. Fences and gates can secure out-of-service buses and train cars, as can remote surveillance methods to keep such vandalism at a minimum. Instead, it is the day-to-day safety and security of transit riders and employees that should become the highest priority. This begins with creating the safest environment possible that is highlighted with appropriate signage and, when necessary, audible warnings, and supporting that with technology, such as surveillance cameras, that will document what has happened if an incident occurs.Analytics can also be useful in alerting security about other suspicious behaviours at a transit stop, such as an untended bag or package Crime prevention in transportation Analytics can also be useful in alerting security about other suspicious behaviours at a transit stop, such as an untended bag or package Incidents of concern within a transit setting can take several forms, ranging from legitimate accidents or crimes to false claims such as faked fall down the stairs to potential and actual suicides. Bus and subway stations also have become magnets for homeless people who may put themselves and others in harm’s way by trying to access less secure public areas within a station as temporary shelters. If someone is injured on a subway platform and the transit provider is held liable, it could be on the hook for hundreds of thousands, if not millions of dollars. Suicides are a major concern for operators, with personnel now being trained to look for individuals who seem distressed, are loitering in the area or are intentionally putting themselves in a dangerous situation, such as standing too close to the edge of a platform. The deployment of video analytics, which can be programmed to send alerts when certain pre-set actions occur, can help determine when such dangerous behaviours come into play. Analytics can also be useful in alerting security about other suspicious behaviours at a transit stop, such as an untended bag or package or a person going into a restricted area. Whether it is on the bus, train or ferry or at the stops themselves, cameras and intuitive video management systems are the key to both active and forensic transit security. Some cities use buses that are up to 60 feet long and those can be equipped with up to a dozen cameras Train security and safety By using the proper cameras and recording systems in a transit environment, quick-acting personnel can locate a person of interest who boarded a train at one station, follow him during his trip and produce a crisp, clear identifiable image at the end. Those setting up the system thus should keep in mind proper camera positioning, resolution and motion-based changes to framerates or other compression settings. A typical 30-foot bus often has six cameras—one each at the front and middle doors, two more within the bus and then one looking forward and another looking behind the bus. The latter two are important in the event of accidents to verify liability. Some cities use buses that are up to 60 feet long and those can be equipped with up to a dozen cameras.Train stations often deploy high-definition cameras to better support facial recognition software to get that actionable image Train cars are similarly equipped with two to four cameras to view activity down the centre aisle. Within the stations themselves, there can be from 15 to 30 or more cameras capturing wide-angle shots. Train stations, which have a restricted point of egress, often deploy high-definition cameras to better support facial recognition software to get that actionable image. Installing the right technology for the solution Although bandwidth and storage can be a concern, with motion-based recording, the resolution can be bumped up during event, resulting in a 1-megapixel stream jumping to 4 or even 8mbps when needed. By changing the resolution on demand, end users can cut their storage needs significantly. Transportation settings often rely on the same technology used in other security installations, primarily mini dome cameras, although there are some mini transit domes built specifically for the environment with the proper aesthetics. Because of vandalism threats, transit typically avoids pendant mounts, which can be more easily grabbed and damaged. Temperature ratings for cameras also come into play in cold climates with cameras often getting outdoor exposure.Today’s new buses and trains are constructed with the cameras onboard and newer stations also take security into consideration at the earliest design stage As trains and buses move along their routes, especially those that service outlying areas, Internet connectivity becomes an issue as well. Because it may be difficult for video to be sent in transit, security bus barns are equipped with Wi-Fi so video from onboard cameras can be downloaded at the end of the day. And the use of hardened recorders at the stations allows security personnel to retrieve recorded video. Transit security with modern technology Today’s new buses and trains are constructed with the cameras onboard and newer stations also take security into consideration at the earliest design stage. Older infrastructure from long-standing subway and bus terminals can prove to be a challenge when adding security, but these issues aren’t insurmountable. Often the solution is to add more cameras to cover the same square footage because of less-than-ideal sight lines and to place conduit wherever it works best, which may mean positioning it under platforms or in other out-of-the-way places within older stations. Looking ahead, transit security will continue to evolve, not only as new stations and modes of transportation are added to the system, but in terms of communicating with commuters. People can expect to get mass notification alerts on their mobile devices, and those same devices can provide vital data to transportation entities to better develop their overall systems.
With the ever-growing availability of video data thanks to the low cost of high-resolution video cameras and storage, artificial intelligence (AI) and deep learning analytics now have become a necessity for the physical security industry, including access control and intrusion detection. Minimising human error and false positives are the key motivations for applying AI technologies in the security industry. What is artificial intelligence? Artificial intelligence is the ability of machines to learn from experience using a multi-layer neural network, which mimics the human brain, in order to recognise items and patterns and make decisions without human interference. The human brain is estimated to have 86 billion neurons; in comparison, the newest Nvidia GPU Volta has 21 billion transistors (the equivalence of a neuron), which offers the performance of hundreds of CPUs for deep learning.AI can learn continuously 24 hours per day every day, constantly acquiring, retaining and improving its knowledge In addition, unlike humans, AI can learn continuously 24 hours per day every day, constantly acquiring, retaining and improving its knowledge. With such enormous processing power, machines using Nvidia GPU and similar chips can now distinguish faces, animals, vehicles, languages, parts of speech, etc. Depending on the required complexity, level of details, acceptable error margin, and learning data quality, AI can learn new objects within as fast as a few seconds using Spiking Neural Network (SNN) to a few weeks using Convolution Neural Network (CNN). While both SNN and CNN offer advantages and drawbacks, they outperform tradition security systems without AI in terms of efficiency and accuracy. According to the research reports of MarketsandMarkets, the market size of perimeter intrusion detection systems is projected to increase from 4.12 billion USD in 2016 to 5.82 billion USD in 2021 at a Compound Annual Growth Rate (CAGR) of 7.1%. Meanwhile, the predicted market of AI in security (both cyber security and physical security) will grow from 3.92 billion USD in 2017 to 34.81 billion USD by 2025, i.e., with an impressive CAGR of 31.38%. Legacy perimeter intrusion detection systems Legacy perimeter intrusion detection systems (PIDSs) are typically set up with the following considerations: Geographical conditions: landscape, flora, fauna, climate (sunrise, sunset, weather conditions, etc.), whether there are undulations in the terrain that would block the field of view of cameras Presence or lack of other layers of physical protection or barriers Integration with other systems in the security network: camera, storage, other defensive lines (door, lock, alarm, etc.) Types of alarm triggers and responses System complexity: intrusion detection with various types of sensors, e.g., microwave sensors, radar sensors, vibration sensors, acoustic sensors, etc. Length of deployment Local regulations: privacy protection, whether the cameras/sensors must be visible/hidden/buried, etc., electromagnetic interferences that may affect other systems such as oil rigs or power plants Human involvement: on-site personnel arrangement, human monitoring, human action in response to alarms AI object detection can easily distinguish different types of people and objects Pain points and benefits of AI The conditions listed above correspond to certain requirements of an intrusion detection systems: minimal false alarm, easy setup and maintenance, easy integration, and stable performance.AI by nature is designed to learn, adapt itself and evolve to work in multiple conditions: it should be integrated with existing video recording systems Minimal false alarms: False alarms lead to increased cost and inefficiency but are the main problem of PIDSs without AI technology, where animals, trees, shadows, and weather conditions may trigger the sensors. AI object detection can easily distinguish different types of people and objects, e.g., in a region set up to detect people, a car driving by, a cat walking by, or a person’s shadow will not trigger the alarm. Therefore, the amount of false alarms can be reduced by 70% to orders of magnitude. Easy setup and maintenance: Legacy PIDSs without AI must account for terrain, line of sight of cameras, sensor locations; any changes to the system would require manual effort to recalculate such factors and may disturb other components in the system. In contrast, AI PIDSs enable the system administrator to access the entire system or individual cameras from the control room, configure the region and object of interest in the field of view of cameras within minutes, and adjust with ease as often as necessary. Computing knowledge and even specific security training are not required to set up a secured PIDS with AI because AI PIDS is designed to relieve humans from knowing the inner working of machines. Easy integration with complementary technologies: Legacy PIDS without AI relies on physical technology, which are often proprietary and require complete overhaul of systems to function smoothly. On the other hand, AI by nature is designed to learn, adapt itself and evolve to work in multiple conditions, so AI PIDS is easily integrated with existing video recording (camera) and storage (NVR) systems. AI also eliminates the need for physical wireless or fiber-based sensors; instead, it functions based on the videos captured by cameras. Furthermore, AI enables easy and instantaneous combinations of multiple layers of defense, e.g., automatic triggering of door lock, camera movement focusing and access control as soon as a specified object is detected in the region of interest, all set up with a click of a button. Stable performance and durability: Legacy PIDSs without AI requires complicated setup with multiple components in order to increase detection accuracy. More components mean a higher probability of malfunction in the system, including exposure to damages (e.g., sensors can be destroyed) and delay in detection, while human monitoring is inconsistent due to human fatigue (studies have shown that a person can concentrate in mundane tasks for only up to 20 minutes, and the attention span decreases even more rapidly when humans are faced with multiple items at once, e.g., multiple camera monitoring screens). AI significantly reduces, if not completely eliminates the need for human involvement in the intrusion detection system once it is set up. In addition, AI reduces the risk of system malfunction by simplifying the hardware sensors needed. Minimising human error and false positives are the key motivations for applying AI technologies in the security industry Additional benefits of AI in intrusion detection Artificial Intelligence is undeniably reshaping every business and weaving into every aspect of daily lifeMaximal detection capability: The most advanced AI intrusion detection system today provides an all-in-one solution to distinguish any combination of alarm-triggering criteria beyond perimeter protection. Using AI, the system administrator can configure as many zones with different settings and object of interests as necessary, which include detections for specific colors or attributes (e.g., person not wearing the required uniform or carrying food/drink), numbers and dwell time (e.g., group of more than 5 people loitering), or movements (e.g., cars moving faster than the speed limit). In addition, AI can accurately pinpoint the location of event occurrence by displaying the camera that records the event in near real time, i.e., with few-second delays. Lower security operation cost: By minimising the number of false positives and human involvement while maximising ease of use and stability, AI intrusion detection systems significantly decrease the total cost of ownership. Companies can reduce the large security personnel overhead and cost of complicated and expensive legacy PIDSs systems. McKinsey Global report in June 2017 shows that proactive AI adopters can realize up to 15% increase in profit margin across various industries. Artificial Intelligence is undeniably reshaping every business and weaving into every aspect of daily life. In security, legacy systems are giving way to AI-based systems, and the first enterprises to adopt AI-based systems will soon, if not immediately, benefit from such investment.
