Impact of sophisticated IT technologies on the security market
Impact of sophisticated IT technologies on the security market

Over the course of the past few months, I have discussed a myriad of topics, from Big Data, the Internet of Things and emerging video surveillance-use cases, to analytics, storage complexities and IT technologies like virtualisation and hyperconverged infrastructure (HCI). All of these trends have a significant effect on the security market, and in April they were highlighted in spades at ISC West. It’s great to talk about these trends but it’s far better to see how they are being leveraged in real-world applications. That’s really where we can all see the true value of new solutions and concepts. We’re lucky enough to work with some leading organisations that want others to benefit from their experience and I’m happy to have the opportunity to share two of these applications with you. Protecting educational facilities UCF has adopted advancements in technology, particularly video surveillance solutions, to help ensure stronger security on campus Educational institutions face an increasingly complex risk environment. Recent high-profile incidents emphasise these risks and magnify the vulnerabilities that educational facilities face. These incidents have led to more public demand for improved security solutions across campuses. The primary mission of these organisations is to deliver quality education to students, and they face the challenge of balancing between a highly secure facility and one that supports open interaction. The University of Central Florida is no different. This organisation, one of the largest universities in the country, has adopted advancements in technology, particularly video surveillance solutions, to help ensure stronger security on campus. Active shooter incidents In March 2013, UCF faced an active shooter situation in which a former student planned to pull the fire alarm in a residence hall and then attack his classmates as the building was evacuated. However, the shooter’s gun jammed, and as officers were closing in on the gunman, he took his own life. During the university’s response to the incident, accessibility to critical video data was a major issue. Educational institutions face an increasingly complex risk environment UCF had cameras in the area where the incident took place, but first responders had no way of viewing the footage without being at the physical location of the video recorder. At the time, UCF had a wide variety of standalone systems in place, including non-integrated video surveillance, access control and intrusion systems. As a result, there was no way to centralise video management, viewing and analysis. Upgrading from analogue systems Altogether, its security system consisted of older analogue platforms that were reaching end of life, 58 standalone servers, 12,000 access points and a wide variety of DVRs — all being managed in a siloed manner. UCF needed a solution that would allow officials to centralise system management, store video data more effectively and reliably, and enable the security team to deliver situational awareness to responders when needed. Security leaders sought a way to further modernise its security, surveillance, access control and IT infrastructure The university deployed an HCI solution, one that is optimised for demanding, data-intensive workloads like video surveillance. Using standard off-the-shelf server hardware, the system aggregates the storage and compute resources from multiple servers into a single unified pool that all cameras can access, which maximises performance and storage capacity utilisation. The platform also hosts the university’s video management solution, which serves as a centralised source to manage video and effectively protect its security data. Because of the growing demand for video across UCF's campuses — for both safety and business purposes — the HCI solution’s ability to eliminate the opportunity for data loss and easily scale were key components in its selection. Protecting air travel and airports In 2012, Charleston International Airport embarked on an ambitious upgrade project dubbed the Terminal Redevelopment and Improvement Program. The $200 million initiative was designed to modernise and expand the facility to meet increased passenger demand. While the aesthetics and amenities of the airport were under construction, security leaders sought a way to further modernise its security, surveillance, access control and IT infrastructure. The IT and security teams needed to address the challenges of their existing standalone server environment, which included siloed systems, management complexity and high administrative and equipment costs. Charleston International Airport embarked on an ambitious upgrade project dubbed the Terminal Redevelopment and Improvement Program Considering the high value of the airport’s video, security and IT data, it required a solution that could deliver reliable data protection, system resiliency and fault tolerance. The airport is required to store video for 30 days, but it seeks to expand its retention time to 60 days. Therefore, technology that can scale simply was key in the selection process. Storage system updates It also required a storage platform that could manage the demanding and write-intensive nature of its nearly 250 IP surveillance cameras — a challenging task for traditional video recorders. The airport deployed HCI appliances to better manage captured video data and expand its archive capability for video surveillance. Users rely on video to validate whether something did or did not happen - and this is essential in airports HCI surveillance solutions are designed to provide industry-leading resiliency. Even if multiple hardware failures occur, including an entire appliance, video management servers will remain online and recording, and any previously recorded video will continue to be protected and accessible. Reducing expenses and costs The solution also reduced total cost of operations by consolidating servers, storage and client workstations into one enterprise-class solution that is easily managed from a single user interface, without the need for specialised IT skills. These use cases demonstrate the value emerging technologies bring to these types of modern environments. And they show that solutions like HCI are no longer simply much-talked about technology trends. Video, IT and security data is critical to organisations of all types and they need to ensure their investment in capturing this data is protected. From a security standpoint, users rely on video to validate whether something did or did not happen. If that video data isn’t protected, they lose a very valuable investigative tool. That isn’t an option in today’s complex environment. That’s is why it is paramount to understand how new technologies can help expand current capabilities and evolve security operations. This can’t be left to chance.

How video analytics maximise the value of your surveillance system
How video analytics maximise the value of your surveillance system

Despite the huge amount of video data collected, statistics show that only 10 percent of data is ever used and most loses its value within seconds of being generated. Why use such a limited amount of data? Many security organisations are focused on delivering the right information in case of an emergency or providing the correct evidence after a criminal act. Yet the fact is, a new video security system can be a large investment. Together with the service, maintenance and management costs associated with it, most video systems are currently considered overhead. So how can you maximise the value of your video system? Video analytics ensure surveillance images are continuously analysed in real-time to alert users to things that need attention. This helps organisations make sense of video data and adds an extra layer of protection by providing alerts to potential security risks before or as they occur, such as detecting loitering in a parking lot or a perimeter breach after hours.Integrating analytic alerts with other security systems enables organisations to use the data to trigger responses from other components of the security solution Video analytics can be programmed to alert on things such as line/perimeter crossing, illegal parking, loitering: people counting, speeding in areas like parking lots, colour matching alerts. These are just some of the ways video analytics can assist to enhance security and safety. Video analytics trigger system events Integrating analytic alerts with other security systems enables organisations to use the data to trigger responses from other components of the security solution. This can increase overall security, better mitigate risk, and reduce complexity for users to improve efficiency. For example, intelligent cameras equipped with video analytics can initiate intrusion detection system events when alarms are triggered. The analytic alert can immediately fault a corresponding point on the panel. This can prompt the panel to communicate the alarm to the central station or to send video snapshots to security personnel. In a retail store or warehouse environment, video analytics can also alert to an emergency exit that has been blocked by a pallet of boxes or by another object. Using an idle object rule, the IP camera with analytics can alert when an object remains in the area for longer than a pre-defined amount of time. People counting and crowd detection can also help organisations improve customer satisfaction by monitoring for long lines or people gathered in an area When this occurs, the alert can fault a point on the intrusion control panel, which can then send an email or text message with a video snapshot to the store or warehouse manager. This can help to prevent code violations and unsafe conditions. Extending beyond security Not only can video analytics detect threats, alert to security breaches, and help enforce health and safety regulations, it can also do much more. It can enable organisations to re-purpose the data for new uses for the business—offering valuable insights to other departments within an organisation, such as providing the ability to analyse behaviour in retail stores to help merchandisers create more effective display placements. How is this possible? Analytics can provide organisations with the additional information about video data that they need to re-purpose it for a business advantage. The cameras can interpret data directly at the source and re-assign it to help organisations make smarter decisions.By providing business information that goes beyond conventional security applications, new functionality can easily be added to a video security system This includes monitoring presence to reduce utility bills, identifying patterns in customer activity to improve sales, and distinguishing road blocks to optimise retail shop layout and increase customer satisfaction. Improving customer satisfaction People counting and crowd detection can also help organisations improve customer satisfaction by monitoring for long lines or people gathered in an area, indicating additional assistance may be needed. By providing business information that goes beyond conventional security applications, new functionality can easily be added to a video security system. In this way, video analytics can help organisations reduce costs, increase efficiency, and improve sales. The organisation gains greater value from the system and a return on investment that can be measured in tangible business results. Then, the video system is no longer considered overhead. Overall, using video analytics as part of an integrated security system and fully using the data gained from the analytics can help you better meet your organisation’s needs for security and extend surveillance data to deliver additional business benefits. I believe that every business should be able to take advantages of these advances in technology - without the need for additional investment or a license fee. Every business is different, and new analytics solutions should be adaptaple to meet your exact needs. Thinking beyond security opens up video analytics to revolutionise how video data will be used in the future and can take data usage to a whole new level.  

Security at sea: where technology benefits marine environments
Security at sea: where technology benefits marine environments

The term ‘marine’ comes from the Latin mare, meaning sea or ocean, and marine habitats can be divided into two categories: coastal and open ocean. Video surveillance (VS) applications can cover both types of marine environment with system for ships, maritime ports, onshore and offshore installations, etc. We should want to further analyse VS for ships and try to explain the types of ships on which it can be used, the ways in which VS can be used on ships, the typical certifications in use and what features a camera station must have to be installed on a ship. Starting with ships that have a minimum tonnage, around the world we have: liquefied natural gas (LNG) tankers, passengers ships, chemical tankers, crude oil tankers, container ships, general cargo ships and bulk carriers.As the LNG market grows rapidly, the fleet of LNG carriers continues to experience tremendous growth, offering more opportunities for VS Video surveillance for all marine vessels An LNG carrier is a tank ship designed for transporting liquefied natural gas. As the LNG market grows rapidly, the fleet of LNG carriers continues to experience tremendous growth. A passenger ship is a merchant ship whose primary function is to carry passengers by sea. This category does not include cargo vessels which have accommodation for a limited number of passengers, but rather includes the likes of ferries, yachts, ocean liners and cruise ships. A chemical tanker is a type of tank ship designed to transport chemicals in bulk. These ships can also carry other types of sensitive cargo which require a high standard of tank cleaning, such as palm oil, vegetable oils, tallow, caustic soda and methanol. An oil tanker, also known as a petroleum tanker, is a merchant ship designed for the bulk transport of oil. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets. Container ships are cargo ships that carry their entire load in truck-size intermodal containers: a technique called containerisation. They are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo. Today, about 90% of non-bulk cargo worldwide is transported by container. A cargo ship or freighter ship is any sort of ship or vessel that carries cargo, goods and materials from one port to another. Cargo ships are specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Bulk carriers make up 15%–17% of the world's merchant ships and they are specially designed to transport unpackaged bulk cargo such as grains, coal, ore and cement in its cargo holds. For all these ships the protection of vessels, cargo and crew is a priority, that’s why the adoption of VS technology plays a key part in terms of security and safety. Human error is regularly named as a major factor in ship accidents, and one way to avoid it is to aid seafarers by providing them with technology and equipment that is reliable and easy to use in all weather and sea conditions. Marine VS encompasses liquefied natural gas (LNG) tankers, passengers ships, chemical tankers, crude oil tankers, container ships, general cargo ships and bulk carriers Emergency security solutions on ship One of the most important applications for camera stations is during “docking”. Mooring is the securing or confining of a vessel in a particular location with a fixed or a floating object (jetty, pier, ship, barge, buoy, etc.) as various cargo operations are carried out. Docking is the final stage of mooring operations when the ship docks to the jetty. This is a very delicate operation and cameras are very helpful in making sure docking is done without accidents.'Man overboard’ is an emergency in which a person has fallen off a boat or ship into the water, and can happen at any time during the day or night Another important application for camera stations is the Man Overboard detection system (MOB). ‘Man overboard’ is an emergency in which a person has fallen off a boat or ship into the water. Man overboard events can happen at any time during the day or night, in all types of weather and sea conditions, and from almost any location on the ship, ranging from a few tens of feet above the water, to over 180 feet.  When these events occur, the immediate availability of important data is crucial. Accurate confirmation of the event including time of occurrence, location on the ship and location in the sea is critical. A proactive detection system must immediately and accurately detect man overboard events and provide prompt, actionable data to response personnel. A typical man overboard detection system can report a MOB event in under 1 second. VS on a vessel can also monitor the engine room at all times and provide a good view of people working on dock, machinery and stowed equipment. But what are the most important features that a camera station must have to work in one of the most aggressive environments in nature? Marine surveillance must operate in one of the most harsh environments in nature Ruggedised reliability in surveillance First of all, and perhaps it’s obvious, but it’s extremely important to have camera stations with amazing reliability. Housing units manufactured from AISI 316L stainless steel, passivated and electropolished, makes the cameras completely impervious to air, water, rusting and corrosion, therefore offering excellent weather protection and increased reliability. Housing units manufactured from AISI 316L stainless steel, passivated and electropolished, makes the cameras completely impervious to air, water, rusting and corrosion Sometimes ships also use cameras constructed entirely from technopolymer, which guarantees high impact resistance and superior protection from external weather agents. Keeping the camera glass clean at all times is another essential feature, and it can be done via a wiper/wash system that greatly reduces the need for maintenance. In the case of PTZ cameras, the best option would be a great pan and tilt speed (up to 100°/s). What is the operative temperature range for the cameras? Sea is everywhere and therefore ships go everywhere, from the Arctic Ocean to the Mediterranean, so we need cameras that have to be fully operational across a wide temperature range.  -40°C to +65°C covers almost all areas. Analogue or IP Cameras? Actually, both options can be used, especially for applications like docking where it’s important to avoid image delay (as can happen with IP cameras due to the natural latency of data communication over a network). Marine certifications Last but not least, the certifications: Certifications guarantee the quality and reliability of camera stations. There is no compromise! One important certification is the Lloyd’s Register Type Approval which subjects cameras to rigorous testing for performance, vibration (critical on ships), humidity, etc. The application field of the LR Type Approval is VS in public places (e.g. passenger ships), open decks, enclosed spaces that are subjected to heat generated from other equipment, and technical premises. Often, VS cameras used in specific areas of ships, such as hazardous areas, are required to have ATEX and IECEX certifications.
