Simplifying the display of multiple cameras from multiple sources has always been a challenge. Early analogue system used multiplexers and matrix switches coupled with many monitors. This created great complexity and cost. Control rooms were very large areas that required many operators. Energy to operate these control rooms was very high. Today, modern technology has enabled the simplification of the control room and the display of video sources along with other vital information. As the industry migrates from traditional analogue devices to IP network devices, consolidation of equipment is shrinking the space requirement for control rooms. The use of TCP/IP connectivity is enabling the linking of information systems such as weather, traffic, and other agency data along with the video feeds. New display technology now allows multiple images to be put together on a single display or span many displays. Content can now be dynamically assigned and moved throughout the control room display wall. LED monitors are now more energy efficient and are more durable when viewing 24/7 without the common “burn-in” issues. As a total solution provider, Dahua Technology provides front-end cameras, NVRs, DVRs, as well as complete control centre solutions. Splicing video wall Dahua has been a manufacturer of video wall solutions since 2007. Dahua is one of the largest splicing video wall providers in China. Dahua ranked second with 9.1% market share in the industry. Splicing video walls normally use LCD screens (LED backlight) with a very slim physical bezel, which is quite important when displaying an image across several monitors. The most common bezel in the market is around 5.5 millimetres. Dahua is proud to offer industry leading bezel sizes from 3.5mm. Dahua video wall monitors are available in 46” and 55” panel sizes. The displays have brightness levels from 500 nits to 700 nits to ensure a good view in all ambient light settings. All of the display panels are designed for 24/7 operation. The surveillance industry requirement for video splicing walls far exceeds the requirements of digital signage applications. The surveillance application requires many types of inputs from devices including: IPCs, DVRs, NVRs; local HDMI/DVI/VGA video signals; and the number of the channels are often above 200. The ability to view many inputs with a single output or arrange inputs and outputs to meet the specific requirement can be challenging. Network video matrix – a video wall controller that fits all scenarios In order to meet those tough requirements, Dahua utilises its experience of network video encoding and decoding technology in video matrix development. There are several technologies of video wall display in the market currently. One way is using PC-based or server-based hardware to extend some graphics cards and develop software to control the output of the graphics card (It is called “virtual matrix” by some VMS vendors). Virtual matrix switches have specific disadvantages. Operating System vulnerabilities, graphic card limitations, and limited scalability make this solution less than optimal. Dahua network video matrix is an embedded hardware specially designed for video wall solutions. Based on Advanced Telecom Computing Architecture (ATCA) architecture, it offers a redundant design for many important parts, such as fans and power, which greatly enhance its reliability and stability. In order to lengthen service life and make repair easy, modular design is used . The matrix consists of 3 parts: mainframe, encoding card and decoding card. The mainframe offers power, control, network and high bandwidth backplane for different cards. For the encoding card, the company offers multiple kinds of video interfaces including HDMI/ DVI/ VGA/ HDSDI/ HDCVI/ CVBS, etc. It is easy to input any kind of supported signal to this matrix with just the selection of the corresponding encoding card. Besides all these local video signals, it has a great capacity for network video streams such as IPCs, NVRs DVRs, etc. For the decoding card, it provides high network video decoding ability and offers the video output channel for both network video and local video signal as well. For pure network application, one matrix can decode 160ch@1080P/ 640ch@D1 network video streams and support up to 40 screens. Combine this network video matrix with the video wall to provide a perfect solution for centralised visualisation in surveillance applications. Another interesting trend In splicing video wall applications, LCD and DLP technology is already mature and be widely used in the market for several years. However, the LED modular technology comes into this market, growing with increasing share. DLP use has dropped with the trend towards LCD and LED Modules. The smaller pixel pitch of LED Modules is leading to higher adoption for indoor use. LED Modules have compelling advantages including: No physical seams, 281 trillion gorgeous colour, high brightness, high refresh frequency, long lifespan, and easy maintenance. Dahua believes that with the costs reduced, LED Modules will become a new driving force in video wall applications. LED Modules are being used today for many indoor applications including: performance venues, advertising, information display, and promotional video. Hybrid systems of LED Modules and LCD Displays are being used more frequently in surveillance control room applications.Add to Compare

Today, the world is connected like never before. Your watch is connected to your phone, which is connected to your tablet and so on. As we’ve begun to embrace this ‘smart’ lifestyle, what we’re really embracing is the integration of systems. Why do we connect our devices? The simplest answer is that it makes life easier. But, if that’s the case, why stop at our own personal devices? Connection, when applied to a business’ operations, is no different: it lowers effort and expedites decision making. Integrating security systems Systems integration takes the idea of connected devices and applies it to an enterprise Systems integration takes the idea of connected devices and applies it to an enterprise, bringing disparate subcomponents into a single ecosystem. This could mean adding a new, overarching system to pull and collect data from existing subsystems, or adapting an existing system to serve as a data collection hub. Regardless of the method, the purpose is to create a single, unified view. Ultimately, it’s about simplifying processes, gaining actionable insights into operations and facilitating efficient decision-making. Although integration is becoming the new norm in other areas of life, businesses often opt out of integrating security systems because of misconceptions about the time and resources required to successfully make the change. So, instead of a streamlined operation, the various security systems and devices are siloed, not communicating with each other and typically being run by different teams within an organisation. Time-intensive process When systems are not integrated, companies face a wide range of risks driven by a lack of transparency and information sharing, including actual loss of property or assets. For example, a team in charge of access control is alerted to a door being opened in the middle of the night but can’t see what exactly is taking place through video surveillance. Without integrated systems they have no way of knowing if it was a burglar, an equipment malfunction or a gust of wind. Without integration between systems and teams, the ability to quickly put the right pieces in front of decision makers is missing. Instead, the team would have to go back and manually look for footage that corresponds with the time a door was open to figure out which door it was, who opened it and what happened after, which can be a time-intensive process. Integrating access control and surveillance systems Theft and vandalism occur quickly, meaning systems and users must work faster in order to prevent it This slowed response time adds risk to the system. Theft and vandalism occur quickly, meaning systems and users must work faster in order to prevent it. Security systems can do more than communicate that theft or vandalism occurred. Properly integrated, these systems alert users of pre-incident indicators before an event happens or deter events altogether. This gives teams and decision makers more time to make effective decisions. Integrating access control and surveillance systems allows for a more proactive approach. If a door is opened when it’s not supposed to be, an integrated system enables users to quickly see what door was opened, who opened it and make a quick decision. Integrated solutions are more effective, more efficient and help drive cost-saving decisions. Ideally, companies should establish integrated solutions from the start of operations. This allows companies to anticipate problems and adjust accordingly instead of reacting after an incident has occurred. Security camera system Although starting from the beginning is the best way to ensure comprehensive security, many companies have existing security systems, requiring integration and implementation to bring them together. Typically, companies with established security systems worry about the impact to infrastructure requirements. Is additional infrastructure necessary? How and where should it be added? What financial or human resources are required? These concerns drive a mentality that the benefits gained from an integrated solution aren’t worth the costs of implementation. Thankfully, this is becoming less of a problem as security providers, like Twenty20™ Solutions, work to offer adaptable solutions. With flexible options, operators don’t worry about adding or replacing infrastructure to align with a provider’s model. This allows users to monitor camera footage and gate traffic from one system If a company has an existing security camera system, but identifies a need for access control, a modern integrated solution provider can supply the gates for access points and equip the gates and cameras with the technology to connect the two. This allows users to monitor camera footage and gate traffic from one system. This model also spares operators additional costs by using a sole vendor for supplemental needs. Overall management of security While a single, unified system is beneficial for cost saving, it can also help the overall management of security. The ability to view all operating systems in one dashboard allows security personnel to manage a site from any location, reducing the expense and effort required to manage a system. The mobile world today means security directors no longer need to be in a centralised operations center to see alerts and make decisions. This simplifies processes by allowing users to quickly see an alert, pull up a camera, delete a user or check an access log from a phone. Modern networks are secure and accessible to those with permissions, without requiring those users to be physically present. Consolidating security systems is the first step companies can take toward streamlining work, information and costs. The next step is integrating all sites, both remote and on-grid. Energy and communication technology The integration of sites and systems turns mountains of data and information into actionable intelligence Traditional methods demanded two systems: one for on-grid facilities and another for off-grid locations. With advancements in energy and communication technology, the need for multiple systems is gone. Data from remote sites can be safely and securely fed into an existing system. These remote locations may gather, distribute and manage data in a different manner than a connected system due to the cost of transmission via remote connections (i.e., cellular or satellite connection). The end result, however, is a consistent and holistic view of operations for the decision maker. The integration of sites and systems turns mountains of data and information into actionable intelligence. With connected devices monitoring occurrences at individual sites, as well as events across locations, the data tells a story that is unhindered by operational silos or physical space. Identifying patterns and trends Instead of providing 10 hours-worth of footage that may or may not be relevant, system analytics can provide users with the specific set of information they need. Incidents once discarded as ‘one-off’ events can now be analysed and data-mapped to identify patterns and trends, directing future resources to the most critical areas first. Consumers are increasingly expecting everything they need to be right where they need it – and businesses are right behind them. The current generation of security professionals are increasingly expecting the simplicity of their everyday personal tasks to be mirrored in enterprise systems, which means giving them the ability to see what matters in one place. A unified system can provide just that, a single view to help simplify processes, promote cost saving and accelerate decision making.
Artificial intelligence (AI) is improving everyday solutions, driving efficiency in ways we never imagined possible. From self-driving cars to intelligent analytics, the far-reaching impacts of Deep Learning-based technology empower human operators to achieve results more effectively while investing fewer resources and less time. By introducing AI, solutions are not merely powered by data, but they also generate valuable intelligence. Systems which were once leveraged for a narrow, dedicated purpose, can suddenly be engaged broadly across an organisation, because the previously under-utilised data can be harnessed for enhancing productivity and performance. Video analytics software The video intelligence software processes and analyses video to detect all the people and objects that appear When it comes to physical security, for instance, video surveillance is a standard solution. Yet, by introducing AI-driven video analytics software, video data can be leveraged as intelligence in previously inaccessible ways. Here are some examples of how diverse organisations are using AI-based video intelligence solutions to enhance security and performance with searchable, actionable and quantifiable insights. Law enforcement relies on video surveillance infrastructure for extracting investigation evidence and monitoring people and spaces. Instead of manual video review and live surveillance – which is prone to human error and distraction – police can harness video content analysis to accelerate video investigations, enhance situational awareness, streamline real-time response, identify suspicious individuals and recognise patterns and anomalies in video. The video intelligence software processes and analyses video to detect all the people and objects that appear; identify, extract and classify them; and then index them as metadata that can be searched and referenced. Maintaining public safety For law enforcement, the ability to dynamically search video based on granular criteria is critical for filtering out irrelevant details and pinpointing objects of interest, such as suspicious persons or vehicles. Beyond accelerating video evidence review and extraction, police can leverage video analysis to configure sophisticated real-time alerts when people, vehicles or behaviours of interest are detected in video. Instead of actively monitoring video feeds, law enforcement can assess triggered alerts and decide how to respond. In this way, officers can also react faster to emergencies, threats and suspicious activity as it develops. Video analysis empowers cities to harness their video surveillance data as operational intelligence Empowering law enforcement to maintain public safety is important beyond the benefit of increasing security: A city with a reputation for effective, reliable law enforcement and enhanced safety is more likely to attract residents, visitors and new businesses, exponentially driving its economic development. Furthermore, in cities where law enforcement can work productively and quickly, time and human resources can be reallocated to fostering growth and building community. Video surveillance data Video analysis empowers cities to harness their video surveillance data as operational intelligence for optimising city management and infrastructure. When video data is aggregated over time, it can be visualised into dashboards, heatmaps and reports, so operators can identify patterns and more seamlessly detect anomalous behaviour. A city could, for instance, analyse the most accident-prone local intersection and assess the traffic patterns to reveal details such as where cars are dwelling and pedestrians are walking; the directional flows of traffic; and the demographic segmentations of the objects detected: Are cars lingering in no-parking zones? Are pedestrians using designated crosswalks – is there a more logical location for the crosswalk or traffic light? Do vehicles tend to make illegal turns – should police proactively deter this behaviour, or should the city plan new infrastructure that enables vehicles to safely perform these turns? Finally, does the rise in bike traffic warrant implementing dedicated biking lanes? With video intelligence, urban planners can answer these and other questions to facilitate local improvements and high quality of life. By leveraging the video insights about citywide traffic, public transit organisations can make data-driven decisions about scheduling and services Enhancing situational awareness Insight into traffic trends is also critical for transport companies, from public transit services to transportation hubs and airports. By leveraging the video insights about citywide traffic, public transit organisations can make data-driven decisions about scheduling and services. Analysing video surveillance around bus stops, for instance, can help these companies understand the specific hours per day people tend to dwell around bus stops. Correlating this information with transactional data for each bus line, bus schedules can be optimised based on demand for individual bus lines, shortening waiting times for the most popular routes. Similarly, the traffic visualisations and activity heatmaps derived from the video of major transit hubs, such as international airports and central stations, can be beneficial for increasing security, enhancing situational awareness, identifying causes of congestion, improving throughput and efficiency and, ultimately, solving these inefficiencies to provide a streamlined customer experience for travellers. Large education campuses Campus law enforcement can leverage video data to increase situational awareness and public safety Much like a city, large education campuses have internal transportation services, residential facilities, businesses and law enforcement, and video content analysis can support the campus in intelligently managing each of those business units, while also providing video intelligence to these individual groups. Campus law enforcement can leverage video data to increase situational awareness and public safety, driving real-time responses with the ability to make informed assessments and accelerating post-event investigations with access to easily extractable video data. When campuses are expanding or developing additional infrastructure, they can plan new crosswalks, traffic lights, roads, buildings and entrances and exits based on comprehensive video intelligence. By understanding where pedestrians and vehicles dwell, walk, cross or even violate traffic laws, the campus can inform construction projects and traffic optimisation. Countless business operations The campus can leverage video business intelligence to justify leasing pricing for different retailers across campus Finally, the campus can leverage video business intelligence to justify leasing pricing for different retailers across campus, demonstrating property values based on traffic trends that can be correlated with retailer point of sale data. Whether its empowering security, productivity or decision-making, the insights generated by AI-based technology can drive significant optimisation – especially when data is fused and cross-referenced across smart sensors and systems for even deeper intelligence. In the case of AI-backed video analytics, diverse organisations can harness video surveillance impactfully and dynamically. Whereas once video technology investments could be justified for their security value – with the introduction of AI capabilities – procurement teams can evaluate these solutions for countless business operations, because they offer broadly valuable intelligence. And video surveillance and analytics is merely one example of AI-driven solutions’ potential to disrupt business as we know it.
It had been a particularly slow night. The plant security guard had just made his rounds on this Sunday evening shift. As soon as he passed the weighing scales, he could enter the guard shack and get off his feet. Challenging a curious incident However, on this night, he noticed the waste vendor’s truck sitting half on and half off the scale. He stopped dead in his tracks to see if the truck would back up and completely sit on the scale. It never did. The observant guard walked up to the truck and challenged the driver who seemed surprised. “Hey, you’re not weighing your truck properly.” The driver fumbled for a response before replying, “Sorry, I was on the phone with a friend. I didn’t notice it.” But this security guard had the presence of mind to demand the driver’s phone. The driver was caught off guard and surrendered the phone. The guard then pulled up the most recent incoming/outgoing calls and saw no calls during the last 30 minutes. “I don’t think so.” “You don’t think so what?” The security guard was frank, “You haven’t used this phone in over half an hour.” The truck driver sheepishly acknowledged the fact. It was decided to install CCTV covering the weighing area and scales – no easy feat due to poor lighting Preventing crime as it happens Knowing the driver was lying, the security guard ordered the truck back on the scale for a correct weighing and advised the driver that he would report the incident. The security guard wrote up his report and handed it off to his supervisor who, in turn, contacted the local corporate investigator. This investigator was soon on the phone with his boss at corporate headquarters on the other side of the world. Together with Security, they decided to install CCTV covering the weighing area and scales – no easy feat due to poor lighting. However, once completed, they waited. They would not have to wait long. For the next two months, the waste vendor trucks, filled to the brim with production waste, black-and-white paper and other waste products from the plant, would stop on the scale only for a moment and then drive the front half of the truck off the scale for weighing. It was obvious that the vendor was cheating the company by only paying for half the waste. After two months, it was decided to catch the next cheating driver “en flagrante.” Sure enough, the next truck went half on and half off the scale and was weighed. Security then asked the unsuspecting driver to park his truck and invited him inside the building to talk to a supervisor. The driver signed an incriminating statement about the scheme and his role therein. They sent him on his way asking him to keep it quiet Waiting for the driver in a large office was the local investigator and his close friend, the Head of Security. After a difficult interview, the driver admitted to cheating on the scales over a two-year period—he claimed that some of the scale cheating was done at the direction of the vendor’s management, while some of it he did himself by “ripping off” the vendor—which he acknowledged was dangerous. Working with authorities The driver signed an incriminating statement about the scheme and his role therein. They sent him on his way asking him to keep it quiet—they would see what they could do for him later on. In the meantime, Corporate Investigations had received a due diligence report on the vendor company which contained disturbing news—the company and its managers were associated with a countrywide waste management mafia. The report suggested that the vendor had a reputation for thefts and involvement in numerous lawsuits regarding thefts and embezzlement. Shockingly, no prior due diligence had ever been conducted on the vendor. Fortunately, the plant’s finance and audit team had maintained good records over the past 5 years and were able to re-construct the amount of waste going out the plant door and the amounts being claimed and paid for by the vendor. The discrepancy and loss stood at a multi-million dollar figure. After consulting with the local police authorities and company lawyers, it was decided to pursue a civil case against the vendor. Pursuing legal action The regional lawyer, the Head of Investigations, the Head of Security and the CFO invited the vendor to discuss the problem. Some of the evidence was shown to the vendor’s CEO who became indignant and, in order to save face, promised to fire the truck drivers and to repay any losses for the last two months. Inter-dependent entities - security, investigations, finance/audit and legal - combined their resources and agendas to form a unified front That was not enough for the company and a protracted legal battle ensued which lasted several years and resulted in the vendor’s paying almost the entire amount in instalments. The vendor was dropped from the contract and internal controls strengthened—the only plant employee dealing with the waste issue left the company and was replaced by two individuals. The plant also began paying more attention to the waste process and less to the production side. Several “lessons learned” come to mind. First, the tripwire came in the person of an astute and well-trained security guard who exhibited some of the best characteristics you want to see from men and women in that profession. The Security Department was also adept at installing the CCTV and capturing the fraud live on videotape. But a far greater lesson was learned—of what can happen when inter-dependent entities (security, investigations, finance/audit and legal) within a company combine their resources and agendas to form a unified front. The results speak for themselves.
