Veeam® Software, the provider of backup, recovery and data management solutions that deliver Modern Data Protection, recently announced it has been chosen by City of Victoria to build its city’s business resiliency and increase its security posture by providing unmatched modern data protection, backup and disaster recovery. To support the city’s thriving economy and vibrant arts and culture scene, City of Victoria knew business resiliency and cybersecurity had to be main priorities, which meant making sure data is always protected and accessible. Located at the southern tip of Vancouver Island and serving as the capital city of British Columbia, Victoria is a modern, forward-thinking city known for its convenient city services. From water distribution, garbage collection and emergency assistance to recreational classes, transportation planning and landuse development, these city services are foundational to the city’s strong and successful community. With numerous IT systems supporting city services, ensuring reliability and accessibility for all 94,400 residents is one of the city’s highest priorities. So, when City of Victoria’s legacy backup solutions failed to match the agility and efficiency of Microsoft Azure Stack hyperconverged infrastructure (HCI) which is what all systems run on, the IT team knew it had to look for a solution that would dovetail with that simplicity. “Our goal is to always have 100% confidence that data remains protected and city services are always available, so when looking for new solutions, Veeam Backup & Replication™ stood out to us,” Mike Palmer, CIO for the City of Victoria said, “At the time, ransomware was just beginning to surface as a threat, and Veeam had the added benefit of helping increase our ransomware protection. Business resiliency and cybersecurity are two of the city’s biggest priorities, so having a reliable solution like Veeam means there’s no second guessing.” With Veeam Backup & Replication, City of Victoria can build business resiliency by simplifying backup and disaster recovery and increase its security posture by boosting ransomware protection – preventing, detecting and restoring data should a ransomware attack take place. Today, ransomware is worse than ever and the attacks against all industries are only increasing. With the threat of new ransomware models continuing to be a leading concern facing business leaders, a solution that protects all data against accidental deletion, security threats and retention-policy gaps was a huge factor in decision making. Veeam also provides total access, control and protection of city data with Veeam Backup for Microsoft Office 365. Now, City of Victoria can back up 25 TB across 130 Microsoft Hyper-V and VMware vSphere VMs in Azure Stack HCI on-premises and send backup copies to tape, so data is air gapped regardless of it being stored on-premises or in the cloud. Veeam gives City of Victoria’s IT team the ability to go further back than 90 days for SharePoint and 30 days for Exchange items, which is critical for legal and regulatory requirements and helps to meet compliance requirements with efficient search and recover features. This ease-of-use helps the city make sure data is always protected and accessible – saving at least 10 hours in troubleshooting time each week.  

Keeping visitors safe is the top priority for any large venue. However, with expansive areas to cover, and sometimes millions of visitors a year to look after, manual patrols and security video management are the major challenges these places are facing. To address them, leading auditoriums, arenas and stadiums around the world are deploying smart video solutions that can automate routine security checks and trigger alerts in real time in the event of an accident or other incident, helping security staff respond faster and more effectively. Security and safety challenges at large venues At large venues and sports stadiums, large numbers of visitors increase the likelihood of crowding, accidents, and fire safety risks. For these reasons, the security staff has to constantly keep an eye on all areas of the site. However, the sheer scale of these kinds of sites makes this very difficult, or even impossible, to use traditional manual approaches and patrols to protect the entire complex. The better way: An automated, large-scale, smart video solution One way for auditoriums, arenas and stadiums to protect staff and large crowds of visitors is to deploy smart video solutions. These keep track of large areas in high definition and generate automated alerts in the event of accidents and emergencies, helping security teams to assist visitors far more quickly. The leading smart video solutions also provide ‘tags’ in video footage that allow security teams to search for, and find, footage of incidents much more quickly, which help to deliver further time savings. Outside large venues, smart video solutions with license-plate recognition (ANPR) capabilities can be deployed to control vehicle access and to help large numbers of visitors to park more quickly. This supports better security and safety outcomes, while also improving the visitor experience, especially during popular events. Excellent results at Zayed Sport City Zayed Sport City, which is the number one sports destination in United Arab Emirates (UAE), is a great example of how smart video can improve the safety of sports fans and visitors. The venue, which welcomes 1.7 million visiting sports fans each year, has deployed a Hikvision solution that incorporates more than 600 smart video cameras with different functions and types, deployed across the entire site. This includes coverage of the Zayed Sport City stadium, ice rink, bowling center, tennis center and a range of other sports facilities. With the Hikvision solution, many routine security tasks can be handled automatically, reducing the risk of missed incidents, speeding up responses, and reducing staff workloads and costs. “The Hikvision system’s AI features are very valuable in investigating incidents, and it reduces the time required by our staff significantly.” said Khalid Al Mutawa, Director of Operations for Abu Dhabi Entertainment Company, the company that manages and operates Zayed Sport City, “Streamlining our processes with this system has allowed us to become much more efficient in ensuring both safety and customer experience throughout the complex. The automated security alerts and the HD Video helps us to respond quickly and work with peace of mind.”

Arthur Veinstein, Cellebrite’s General Manager, International Business, commented, “We are thrilled to have a longterm customer choosing to continue modernizing its investigative efforts through increased adoption of Cellebrite’s DI solutions. Adoption of our solutions at the national level will enhance collaboration among the police force’s examiners and investigators, resulting in more efficient and effective investigations.”  

When CK Communications was asked to upgrade all of Cardiff’s traffic control rooms from analogue to IP, they called on video transmission and networking experts AMG Systems to help move video and data to more than 30 separate monitoring locations across the city. Cardiff-based CK Communications has a 22-year history and offers a unique service integrating CCTV, RPS, VMS, fibre, security and electrical services from design stages through to installation and commissioning. The company’s projects include city centres, council-owned buildings, data centres, motorways and tunnels and it works closely with the main roads agencies in South Wales to provide support on their current and future projects. When CK won the contract to upgrade all traffic control rooms in Cardiff from analogue to IP, it faced a significant task. These monitoring stations include four main and no less than 27 remotely sited control desks across the city. The control rooms and desks are required for the use of police, urban traffic control (which has responsibility for traffic signals across Cardiff), a Silver Command post for major events including monitoring large-scale football and rugby match days, tunnel service buildings, bus depots and more. According to Ian Jones, the existing Cardiff traffic monitoring network was very much in need of an upgrade. He describes it as formerly ‘an analogue beast.’ “It meant there was lots of video switching, and video matrixes dotted all over the place,” Ian said, “Our first task was to get all of those camera images from the analogue world on to an IP solution. The products to be used were Pelco, but then we had to send 500 images around the city from a variety of locations to different control rooms. So that’s where AMG came in.” AMG Systems is the leading UK-based manufacturer of environmentally robust fibre, analogue, IP/ Ethernet, wireless and hybrid communication transmission solutions. Ian worked with Sara Fisher, AMG’s Sales and Marketing Director, to design the system which would work best on the existing customer-owned fibre network in place across Cardiff. “That involved utilising lots of Layer 2 switches, as well as fibre switches which are dotted across the city now,” he said, “A significant factor in the installation was that the existing Pelco equipment was only able to unicast a certain number of images; they prefer to use multicast. So AMG provided switches for multicasting (including IGMP and IGMP snooping) and other specific jobs. “Those AMG switches help to send data – including video and audio – to all of the various control rooms and control desks across the city.” CK has also moved Cardiff’s analogue cameras to IP, which has involved using AMG transmission equipment at the edge of the network, integrating into switches CK has built into the nodes. The AMG equipment in use in Cardiff includes AMG 5900 hybrid units, which are able to transmit analogue video, data, audio and Ethernet, a variety of edge-of-network managed and unmanaged switches, 10Gb/s managed switches, both standard and modular, and hybrid (analogue over IP) wireless links. Ian is himself an experienced highways engineer and has been responsible at CK for projects in Cardiff for more than a decade. His first exposure to AMG’s products came about when working on upgrading camera sites on the M25 motorway.  

HID Global, a worldwide company in trusted identity solutions, announced the successful implementation of its HID Mobile Access solution and mobile-enabled readers in Varso Place, the site of the tallest skyscraper in the European Union, which allows more than 7,000 people to move more freely and securely throughout the building. Located in Warsaw, Poland, Varso Place is HB Reavis’ latest development and most ambitious project to date. Designed by world famous British architects, Fosters + Partners, it comprises three buildings in a 144,000 square meter area. The project’s showstopper is the fully glazed 53-story Varso Tower standing at over 310 metres tall. The mixed-use site features prestigious office and public spaces on ground levels, including shops, restaurants and an observation deck at the top of Varso Tower. Due to the size and scope of the project, HB Reavis – a renowned international workspace developer – sought a single access system for the entire building so that every tenant would have a simple, easy-to-use, one-stop solution for security management. It wanted to move away from tenants having to use a traditional keyfob or card-based solution and rather implement a high-tech system that also allows for the management of digital credentials using smartphones as a primary form factor. The solution of choice included HID Mobile Access and mobile-enabled readers from HID Global which are equipped with Bluetooth® Low Energy (BLE) and Near Field Communication (NFC) technologies, as well as a Software Development Kit (SDK) that integrates with HB Reavis’ More App. The app covers all building services from concierge services, events, room booking systems, car or bike sharing, and of course, easy access when people enter and exit and move around. As the SDK can be developed and upgraded over time as requirements change, HB Reavis is able to maximize the long-term benefit of mobile security. The mobile, contactless solution – which supports Android and iOS-based smartphones – has been particularly beneficial during the COVID-19 pandemic as it minimizes surface contact and the human-to-human interaction that is typical when issuing and managing physical cards and keyfobs. “Not only does mobile access provide state-of-the-art security control, there is no need to remember to take a pass with you when you leave home or move around the building. When security is based on the phone, it is frictionless, because people always have their phones with them,” said Jakub Kacer, Security Manager at HB Reavis. With the support of HID Global, HB Reavis can ensure a seamless access control solution that enhances the user experience for tenants and employees at Varso Place who access the building’s facilities every day.

Evolv Technology, the player in weapons detection security screening, recently announced results from its partnership with Mercedes-Benz Stadium in Atlanta to provide a more enjoyable, frictionless, and safe experience for fans. The stadium uses the company’s artificial intelligence (AI)-based system, Evolv Express®, to screen fans as they arrive at the stadium for games and other events, without requiring them to stop or remove items from their pockets or policy-compliant bags. Prior to installing Evolv Express, seven out of ten fans cited their arrival at the stadium as an area of frustration and dissatisfaction. Since implementing Evolv Express, nine out of ten fans say that security screening is not a point of contention for them. The stadium has also dramatically reduced the percentage of guests flagged for a security recheck and increased the speed of entry for fans. The stadium, home to the NFL’s Atlanta Falcons and MLS’s Atlanta United, hosts an average of 40-50 major events and more than 200 private events each calendar year including the SEC Football Championship, Chick-fil-A Peach Bowl, and countless concerts by world-renowned artists. “Our objective is to make attending events at Mercedes-Benz Stadium feel like you’re walking into a friend’s house – to a place you belong or even own,” said Karl Pierburg, Chief Technology Officer, AMB Sports and Entertainment, parent company of the Atlanta Falcons, Atlanta United, and Mercedes-Benz Stadium, “It was critically important to us to find a way to allow secure entry without degrading the guest experience at all. Evolv has transformed the entry experience for us and contributes to the high marks we get in general when it comes to entry experience, where we rate in the top quarter of all NFL stadiums.” Evolv Express uses powerful sensor technology with proven AI to provide safer, more accurate threat detection at unprecedented volumes and speed of entry.

Double the pleasure – double the fun! The tourist attractions of ‘twin’ coastal airports in Varna and Burgas, Bulgaria, bring throngs through customs and ensure a busy scene for Fraport Bulgaria. They have partnered for over 10 years with Milestone Systems for ongoing development of their centralized, efficient and flexible video surveillance system, which meets their security demands as they grow. Fraport Bulgaria moved from analog security technology to an IP-networked Milestone and Axis solution, which enabled them to later add Agent Vi AI analytics then progress into a cloud solution to ease the burden on storage. The networked video management platform centrally navigates all the physical security needs at both airports. CHALLENGE: Analog troubles caused delays Before the migration to Milestone’s virtual solutions, the security and safety at both airports was based on different systems, each with a separate server, with physical storage on local hard drives. Archiving on these video recording servers often had damage from harsh weather conditions. Each system was accessed differently and so slowly that it wasted a lot of time, made it difficult to monitor the condition of all hardware and even impossible to recover data in cases of shutdown. This lack of reliability in the analog approach failed to facilitate the security team’s work. Fraport Bulgaria also wanted the alerts and analytical functions of a digital solution with alarms for violations, so they could operate both reactively and proactively. SOLUTION: Smooth flying with a unified security center Today, an in-house cloud solution for video management with Milestone’s software platform provides centralized, optimized, easy operations, processing the entire flow of security information in a virtual infrastructure. Milestone XProtect Corporate manages over 500 AXIS network cameras. Analytical functions are integrated for metadata utilization. VMWare, Agent VI’s InnoVi™ analytics, AXIS Perimeter Defender. Border crossing signalization alerts to unauthorized access and more. The video Smart Wall has 12 big screens, each with 2 workstations and specialized graphics cards. The system alerts when an event occurs and directs the security team’s attention right to the location. Everything is recorded and documented. Human intervention has been minimized by automating the analytics and response. The Agent Vi software detects and tracks objects, violations or other incidents, and based on pre-set rules, sends a signal for actions. Limiting the people factor helps to avoid human error. “Our response is faster and better informed on which actions to take.” Vladimir Petrov Former Head of Information Technology Fraport Bulgaria RESULTS: An easy, scalable, virtual journey The Fraport Bulgaria solution is a living virtual system that can be upgraded quickly and easily, expanded and reconfigured depending on the changing needs of the airports. When Fraport Bulgaria wants more cameras, adding and integrating is very fast – with just a few clicks. Resources can be added quickly. There is no need to buy additional storage hardware and install it on premises: it’s all organized in a private cloud system. Each virtual machine is protected from unforeseen interruptions at the circuit level, and with access to a centralized disk. The advantage of this architecture is flexibility, security and quick response if necessary. Benefits: Keep climbing over time, open to innovation The changing needs of the company are met by the ongoing updates over time. In 2018 a project was initiated adding AXIS thermal cameras to detect unauthorized stays in certain areas. The airports’ integration of Milestone with the corporate Microsoft Active Directory meant user access to the system could be set based on their security groups. Another platform update gave the integration of a mobile server for user access via a standard web browser, incorporating a mobile app which makes any smartphone or laptop function with the video surveillance like an additional camera, to send other views back to the central system. “The value of Milestone software is it’s an open system that can be upgraded and connected to other systems at any time, to ensure the highest level of security” Vladimir Petrov The Milestone open platform allowed Fraport Bulgaria to add facial recognition for access control in areas that were only admissible with a physical pass. The company also plans to integrate AI for information on crowding and non-compliance with the recommended distance between people, as required by pandemic regulations.    

“In the past, blast furnace inspections were completely manual. Workers needed to use a temperature gun to detect the surface temperature of the furnace, spending a lot of time. Moreover, there were many safety hazards such as gas poisoning and fall injuries. So we have to figure out effective solutions to protect employee health and safety in this dangerous process” Yin Fengwei, a Native of Anshan and the General Manager of the Anshan branch of Yutai Security The steelmaking process is very complicated. Putting the ore into the furnace to make into iron, and then into a piece of steel, requires dozens of processes. During these processes, regular inspection and maintenance of furnaces is the top priority. In the past, inspectors had to climb tens of meters up each furnace, hourly, and measure its temperature with an infrared thermometer gun to prevent accidents caused by overheating. High temperature, poisonous gas, and splashing iron flowers made this working environment totally unfriendly to them. Once the equipment fails, it will not only cause financial loss, but may also cause casualties. Some leading enterprises in the steel industry are striving to overcome the challenges and boost a new mode of production. For example, Angang Steel adopted Hikvision’s automatic temperature measurement solution to help the workers get further away from accidents and dangers, but closer to efficient and safe working conditions. ‘Dedicated doctor’ for blast furnaces Located in the heavy industry base in Northeast China, Angang Steel has a long history and a key role in the industry. In recent years, Angang Steel has actively tried innovative solutions for intelligent manufacturing and to solve problems of health and safety. Take the inspection and maintenance of blast furnaces as an example. Since 2019, Hikvision and the local partner, Yutai Security, have helped Angang Steel to apply thermal imaging to ironmaking blast furnaces. By evaluating the intensity of infrared radiation emitted from objects, thermal cameras have been used in detecting temperature anomalies before a fire starts. They find hot spots and invisible defects on machinery or electrical systems that could indicate a potential problem. They also perform non-contact measurements at the areas that are hard to reach manually. Through the real-time connection between frontend thermal imaging instruments and a back-end system, inspectors could use video streams from different positions in a furnace and monitor the temperature changes in specific areas of the furnace shell, generate reports, and receive timely warnings of temperature irregularities. Apart from the improved working environment, productivity has been raised too. The system is like a ‘dedicated doctor’ for blast furnaces, which automatically measures temperature, generates reports, and also allows workers to search and compare historical data and monitor changes in the furnaces by receiving real-time alerts. Intelligent steelmaking through remote operation Besides the automatic temperature measurement of ironmaking blast furnaces, digital and intelligent solutions in the whole process of steelmaking help workers to remotely perceive complex production sites and schedule the production in real time. Hikvision uses thermal imaging technology to conduct real-time online monitoring of hot blast stoves. In addition, other types of sensors can be used to inspect the operating status of the equipment more accurately. Based on that, early alarms of potential security risks will be raised in the shortest time. In Angang Steel’s steelmaking workshop, the production process can be viewed remotely through Hikvision intelligent video devices and large screens. Through outstanding image brightness processing, high frame rate imaging, and other technologies, the image of molten steel dumping and desulfurization process in high-temperature and high-brightness environments can be generated, and then transmitted to the back end, allowing the workers to view and evaluate the production status in time and ensure the product quality. “Manual detection is definitely incomparable with intelligent monitoring, as it is difficult to reflect the real-time situation and not possible to give an effective early warning. With the Hikvision system installed, we can now obtain key data from the blast furnaces, which can be accurately recorded and easily searched on the computer. For example, we can clearly see and check whether the insulation material is thinning or even falling off. This ensures the seamless progress of production and the safety of the workers,” said Yin Fengwei. More technologies for an intelligent steel plant In terms of production logistics, Hikvision uses AI, optical character recognition (OCR), and other technologies to strengthen Angang Steel’s ability to recognize key information in related processes. For example, the one-button counting function can trigger the video data analysis on the weight and the quantity of the materials. The analysis results can be cross-checked with the existing weight data and the quantity data recorded manually. Then the system can automatically print the information labels of the materials. In addition, Hikvision uses multi-dimensional perception technology to monitor and control the vehicles in the factory intelligently. For example, the fusion of video and radar data can detect vehicle violations by recognizing abnormal speed or driving trails. It provides safety supervision departments with feedback on vehicle violations and abnormal conditions in the factory, and discovers the potential risks of vehicle transportation in advance. Hikvision has been continually developing solutions to respond to the needs of the enterprise users in the steel industry, with solid R&D and rich scenario-based capabilities. Its intelligent technologies are helping more and more steel plants to improve quality and efficiency, as well as alleviating the workers’ workload in harsh working environment and help them work safer and more efficiently.
