Cutting through the hype: AI and ML for the security space
Cutting through the hype: AI and ML for the security space

Today’s organisations face numerous diverse threats to their people, places and property, sometimes simultaneously. Security leaders now know all too well how a pandemic can cripple a company’s ability to produce goods and services, or force production facilities to shut down, disrupting business continuity. For example, a category three hurricane barreling towards the Gulf of Mexico could disable the supplier’s facilities, disrupt the supply chain and put unexpected pressure on an unprepared local power grid. Delivering timely critical information Tracking such risk is hard enough, but managing it is even more difficult. A swift response depends on delivering the right information to the right people, at the right time. And, it’s not as easy as it sounds. Indeed, 61 percent of large enterprises say critical information came too late for them, in order to mitigate the impact of a crisis, according to Aberdeen Research (Aberdeen Strategy & Research). These challenges are accelerating the hype around Artificial Intelligence (AI) These challenges are accelerating the hype around Artificial Intelligence (AI). The technology promises to help us discover new insights, predict the future and take over tasks that are now handled by humans. Maybe even cure cancer. Accelerating the hype around AI But is AI really living up to all this hype? Can it really help security professionals mitigate risk? After all, there’s a serious need for technology to provide fast answers to even faster-moving issues, given the proliferation of data and the speed at which chaos can impact operations. Risk managers face three major obstacles to ensuring business continuity and minimising disruptions. These include: Data fatigue - Simply put, there’s too much data for human analysts to process in a timely manner. By 2025, the infosphere is expected to produce millions of words per day. At that pace, you’d need an army of analysts to monitor, summarise and correlate the information to your impacted locations, before you can communicate instructions. It’s a herculean task, made even more difficult, when we consider that 30 percent of this global datasphere is expected to be consumed in real time, according to IDC. Relevance and impact - Monitoring the flood of information is simply the first hurdle. Understanding its impact is the second. When a heat dome is predicted to cover the entire U.S. Pacific Northwest, risk managers must understand the specifics. Will it be more or less hot near their facilities? Do they know what steps local utilities are taking to protect the power grid? Such questions can’t be answered by a single system. Communication - Once you know which facilities are impacted and what actions to take, you need to let your employees know. If the event is urgent, an active shooter or an earthquake, do you have a fast, effective way to reach these employees? It’s not as simple as broadcasting a company-wide alert. The real question is, do you have the ability to pinpoint the location of your employees and not just those working on various floor in the office, but also those who are working from home? How AI and ML cut through the noise Although Artificial Intelligence can help us automate simple tasks, such as alert us to breaking news, it requires several Machine Learning systems to deliver actionable risk intelligence. Machine Learning is a branch of AI that uses algorithms to find hidden insights in data, without being programmed where to look or what to conclude. More than 90 percent of risk intelligence problems use supervised learning, a Machine Learning approach defined by its use of labelled datasets. The benefit of supervised learning is that it layers several pre-vetted datasets, in order to deliver context-driven AI The benefit of supervised learning is that it layers several pre-vetted datasets, in order to deliver context-driven AI. Reading the sources, it can determine the category, time and location, and cluster this information into a single event. As a result, it can correlate verified events to the location of the people and assets, and notify in real time. It’s faster, more customised and more accurate than simple Artificial Intelligence, based on a single source of data. Real-world actionable risk intelligence How does this work in the real world? One telecommunications company uses AI and ML to protect a mobile workforce, dispersed across several regions. An AI-powered risk intelligence solution provides their decision makers with real-time visibility into the security of facilities, logistics and personnel movements. Machine Learning filters out the noise of irrelevant critical event data, allowing their security teams to focus only on information specific to a defined area of interest. As a result, they’re able to make informed, proactive decisions and rapidly alert employees who are on the move. Four must-have AI capabilities To gain real actionable risk intelligence, an AI solution should support four key capabilities: A focus on sourcing quality over quantity. There are tens of thousands of sources that provide information about emerging threats - news coverage, weather services, social media, FBI intelligence and so much more. Select feeds that are trusted, relevant and pertinent to your operations. Swift delivery of relevant intelligence. To reduce the mean-time-to-recovery (MTTR), risk managers need an accurate understanding of what’s happening. Consider the different contextual meanings of the phrases ‘a flood of people in the park’ and ‘the park is at risk due to a flood’. Machine Learning continuously increases the speed of data analysis and improves interpretation. Ability to cross-reference external events with internal data. As it scans different data sources, an AI engine can help you fine-tune your understanding of what’s happening and where. It will pick up contextual clues and map them to your facilities automatically, so you know immediately what your response should be. Ready-to-go communications. Long before a threat emerges, you can create and store distribution, and message templates, as well as test your critical communications system. Handling these tasks well in advance means you can launch an alert at a moment’s notice. The ability to minimise disruptions and ensure business continuity depends on speed, relevance and usability. AI and ML aren’t simply hype. Instead, they’re vital tools that make it possible for security professionals to cut through the noise faster and protect their people, places and property.

A three-point plan for enhancing business video surveillance
A three-point plan for enhancing business video surveillance

Cyber threats hit the headlines every day; however digital hazards are only part of the security landscape. In fact, for many organisations - physical rather than virtual security will remain the burning priority. Will Liu, Managing Director of TP-Link UK, explores the three key elements that companies must consider when implementing modern-day business surveillance systems.  1) Protecting more than premises Video surveillance systems are undoubtedly more important than ever before for a huge number of businesses across the full spectrum of public and private sector, manufacturing and service industries. One simple reason for this is the increased use of technology within those businesses. Offices, workshops, and other facilities house a significant amount of valuable and expensive equipment - from computers, and 3D printers to specialised machinery and equipment. As a result, workplaces are now a key target for thieves, and ensuring the protection of such valuable assets is a top priority. A sad reality is that some of those thieves will be employees themselves. Video surveillance system Of course, video surveillance is often deployed to combat that threat alone, but actually, its importance goes beyond theft protection. With opportunist thieves targeting asset-rich sites more regularly, the people who work at these sites are in greater danger too. Effective and efficient surveillance is imperative not just for physical asset protection, but also for the safety From this perspective, effective and efficient surveillance is imperative not just for physical asset protection, but also for the safety of colleagues as well. Organisations need to protect the people who work, learn or attend the premises. A video surveillance system is, therefore, a great starting point for companies looking to deter criminal activity. However, to be sure you put the right system in place to protect your hardware assets, your people, and the business itself, here are three key considerations that make for a successful deployment. 2) Fail to prepare, and then prepare to fail Planning is the key to success, and surveillance systems are no different. Decide in advance the scope of your desired solution. Each site is different and the reality is that every solution is different too. There is no ‘one-size-fits-all solution and only by investing time on the exact specification can you arrive at the most robust and optimal solution.  For example, organisations need to consider all the deployment variables within the system’s environment. What is the balance between indoor and outdoor settings; how exposed to the elements are the outdoor cameras; what IP rating to the need? A discussion with a security installer will help identify the dangerous areas that need to be covered and the associated best sites for camera locations. Camera coverage After determining location and coverage angles, indoors and outdoors, the next step is to make sure the cameras specified are up to the job for each location. Do they have the right lens for the distance they are required to cover, for example? It is not as simple as specifying one type of camera and deploying it everywhere. Devices that can use multiple power sources, Direct Current, or Power over Ethernet well are far more versatile You have to consider technical aspects such as the required level of visual fidelity and whether you also need two-way audio at certain locations? Another simple consideration is how the devices are powered. Devices that can use multiple power sources, Direct Current or Power over Ethernet as well are far more versatile and reliable. Answers to these questions and a lot more need to be uncovered by an expert, to deliver a best-of-breed solution for the particular site. 3) Flexibility breeds resilience Understanding exactly what you need is the start. Ensuring you can install, operate and manage your video surveillance system is the next step. Solutions that are simple to install and easy to maintain will always be favoured - for example, cameras that have multiple sources of power can be vital for year-round reliability. Alongside the physical aspect of any installation, there is also the software element that needs to be considered. The last thing organisations need is a compatibility headache once all their cameras and monitoring stations are in place. Selecting cameras and equipment with the flexibility to support a variety of different operating systems and software is important not just for the days following the installation, but also to future-proof the solution against change.  Easy does it Once the system is up and running, the real work of video surveillance begins. Therefore, any organisation considering deploying a system should look to pick one that makes the day-to-day operation as easy as possible to manage. And again - that is all about the set-up. Cameras can also provide alerts if they have been tampered with or their settings changed The most modern systems and technology can deliver surveillance systems that offer smarter detection, enhanced activity reporting so you learn more about your operations, and also make off-site, remote management easy to both implement and adjust as conditions change. For example, camera software that immediately notifies controllers when certain parameters are met - like motion detection that monitors a specific area for unauthorised access. Cameras can also provide alerts if they have been tampered with or their settings changed without proper authorisation. Remote management of HD footage What’s more, the days of poor quality or unreliable transfer of video are long gone. The high-quality HD footage can be captured, stored, and transferred across networks without any degradation, with hard drives or cloud-based systems able to keep hundreds of days of high-quality recordings for analysis of historical data. Finally, the best surveillance solutions also allow for secure remote management not just from a central control room, but also from personal devices and mobile apps. All this delivers ‘always-on’ security and peace of mind. The watchword in security Modern video surveillance takes organisational security to the next level. It protects physical assets, ensures workplace and workforce safety, and helps protect the operations, reputation, and profitability of a business.  However, this is not just an ‘off-the-shelf purchase’. It requires proper planning in the form of site surveys, equipment and software specifications, as well as an understanding of operational demands and requirements. Investing time in planning will help businesses realise the best dividends in terms of protection. Ultimately, that means organisations should seek to collaborate with vendors who offer site surveys - they know their equipment best, your needs, and can work with you to create the perfect solution.

Dahua TechMonth features WizMind and 3 practical monitoring applications of human-based video metadata
Dahua TechMonth features WizMind and 3 practical monitoring applications of human-based video metadata

In a surveillance monitoring context, video metadata refers to the structured details that the user can extract from given video footage. It is data that provides information about other data – a “data about data” in short. Human-based video metadata, as its name suggests, are data derived from human targets in the monitored scene. It can be utilised based on user’s requirements to significantly enhance the management and operation of various application scenarios, while carefully maintaining people’s privacy at the same time. To give some insights into its practical usage, here are three conventional applications of human-based video metadata to adopt based during monitoring needs: 1) Searching targets One of the most common applications of human-based video metadata is for target searching after an event. Intelligent surveillance devices, such as the Dahua WizMind products, offer a Quick Target Search function that can locate suspects in time using their physical attributes. Irrelevant targets in the captured images are filtered out by the back-end devices (IVSS, NVR) or by the platform Target attributes include beard, glasses, mask, hat, etc., which are continuously being developed and increased to meet the requirements of various application scenarios. Irrelevant targets in the captured images are also filtered out by the back-end devices (IVSS, NVR) or by the platform. It can capture up to 640* targets (with attributes) per second with an impressive detection rate of 98%*. Generating statistics In addition, another useful application of human-based video metadata technology is for target statistics. WizMind counts in real time the human targets in the monitored scene and filters them based on target category and direction. The directions include A>B, B>A, or A<>B. And to top it up, it can also generate reports by year, month, and day. It can capture up to 96** objects per frame, providing a detection rate of 98%** and an accuracy rate of 96%**. 2) Detect PPE wearing WizMind can detect wearing PPEs in construction sites including safety hats, protective vests, face masks, and glasses Wearing personal protective equipment or PPE is a must on any construction site. Depending on the scope of the project, monitoring the proper wearing of PPEs on the site could be a tough challenge to implement. The latest PPE Detection Technology of Dahua WizMind can detect wearing of commonly used PPEs in construction sites including safety hats, protective vests, face masks, and glasses. It can even detect the colour of the uniforms (top and bottom) of workers. When a violation has been detected, the site supervisor or manager can be notified via the DMSS mobile app. Similar to target searching and statistics functions, it also offers a detection rate of 98%**, with an accuracy rate of 96%**. 3) Aid city road planning Who would have thought that aside from vehicle-related data, statistics related to people on the street can also be useful in planning city roads? By collecting attributes of pedestrians, directions, and periods, local road planning departments can design better roads tailored for road users and commuters. One good example is the Dahua solution developed for a local organisation in Ireland. Aside from motor vehicles and non-motor vehicles, metadata of pedestrians are also captured on main city roads and streets around plazas. These data are then securely transferred to an SFTP server for further data analysis. The data summary is relayed to the local transportation department to help them plan and manage streets more efficiently. Key Takeaways Human-based video metadata can be effectively utilised to optimise the monitoring operation of various application scenarios. Metadata based on human targets can be used to search suspects after an event, and to generate accurate statistics of the people in the monitored scene. Also, these structured data can be used to detect proper wearing of PPEs in a particular site, and help local transportation departments in planning and maintaining city roads to benefit the general public.

Dahua Technology shows how intelligent cameras enhance safety in nursing homes
Dahua Technology shows how intelligent cameras enhance safety in nursing homes

Patient falls in nursing homes are a serious problem. In the United States, for example, around 1,800 elderly people, living in nursing facilities, die each year from injuries related to falls, according to the Nursing Home Abuse Center. Those patients who survive their injuries often have a reduced quality of life and suffer some form of permanent disability. Rise in nursing home patient falls Figures show that between 50% and 75% of nursing home residents suffer falls each year, twice the chances of falling when compared to seniors who live in a regular residential community. It has been a prevalent challenge to detect falls quickly and effectively, especially when these occur in residents’ bedrooms. In the United Kingdom, the Care Quality Commission has recognised that the use of CCTV may be one of the best ways to ensure safety and quality of care. However, using video surveillance also brings into question other security issues, such as privacy and data protection. Dahua’s WizMind technologies WizMind embraces human-based AI (Artificial Intelligence), for a whole host of applications across verticals This is where Dahua Technology’s WizMind technologies come into play. WizMind embraces human-based AI (Artificial Intelligence), for a whole host of applications across verticals, such as retail, energy, finance, transportation and of course, health and social care. Specific to the health and social care sector are deep-learning algorithms, to protect the privacy of the face and body in real-time, and stereo analysis, which combines dual-lens cameras with three-dimensional scene analysis, in order to detect sudden physical movement, such as falls. Stereo video analysis The growth of AI applications has enabled the greater availability of 3D scene analysis solutions, thereby enabling objects and people to be analysed in three dimensions. Dahua Technology’s stereo analysis uses two lenses, in order to capture separate images of the same scene. It then computes the ‘optical parallax’ of spatial points in the two images, providing 3D information of the scene. The stereo vision mimics the depth of view that comes from humans having two eyes, known as binocular vision. Combined with deep-learning algorithm Combined with a deep-learning algorithm, stereo analysis can recognise event patterns, such as falls and other movement-based behaviours, such as people approaching, the detection of an abnormal number of people in an area, and violent behaviour. In nursing and care homes, stereo analysis cameras can help staff monitor residents, in case of emergency and respond to residents’ problems, such as tripping and falls. The cameras can view all three dimensions of subjects and together with its deep-learning algorithm, can immediately alert staff to any unusual or sudden movement, such as would be evident in a fall. Cameras in communal areas and bedrooms With cameras situated both in communal areas and in bedrooms, the staff is able to respond quickly to incidents With cameras situated both in communal areas and in bedrooms, the staff is able to respond quickly to incidents, which may otherwise stay undiscovered for hours. An example of such a scenario is a nursing home in Singapore, which has a capacity of around 400 beds and is divided into 14 separate living environments, with each designed to be a home-like living area. Dahua cameras with intelligent fall detection technology Dahua cameras, such as IPC-HDW8341X-BV-3D with intelligent fall detection technology were installed, including the provision of 167 stereo analysis cameras inside each bedroom. These trigger an alarm, in the case of incidents, such as a fall, allowing immediate response by staff. Not only does this enhance the well-being and safety of residents, but it also can reduce the nursing home’s labour costs. In addition, Stereo Analysis can also be applied in other application scenarios. An underground unmanned bicycle parking garage in Amsterdam, for instance, has installed Dahua Technology’s behaviour analysis cameras, to detect abnormal events and prevent accidents, such as people tripping and falling, or suspicious individuals wandering around the area. Privacy Protection 2.0 technology While monitoring their situation inside the nursing home, Dahua also adopts Privacy Protection 2.0 technology that features masking of human face and body, to protect the residents’ privacy. It involves the restriction of what can be seen in video images and applies equally to live, and recorded images. Digital masking takes place on the front-end device (e.g. network camera). Dahua’s Privacy Protection 2.0 provides real-time occlusion of the body and face and enables users to access recorded videos, without having to overlay faces with mosaic masks. It also offers additional occlusion options, such as irregular polygons, mosaics and coloured blocks, and allows code exporting based on specified targets, ensuring the privacy of subjects. Privacy and security in evidence collection Stereo video analysis and privacy protection come into their own in nursing homes and healthcare facilities Benefits offered include non-pixelated human targets, allowing for privacy and security in evidence collection. The technology also allows for face and human attributes analysis, without breaching people’s privacy, making it ideal for nursing homes. Stereo video analysis and privacy protection come into their own in nursing homes and healthcare facilities. It allows the close monitoring of residents or patients to help ensure their well-being and safety, while at the same time protecting the privacy of often vulnerable individuals. Dahua TechMonth As part of the Dahua TechMonth, this blog highlights how Dahua’s stereo analysis technology, combined with privacy protection, can provide a valuable tool to help staff respond to incidents quickly and efficiently, including falls, without infringing on people’s data protection rights. In the next blog, Dahua Technology will be discussing the WizMind application of human metadata, enabling users to maximise situational awareness and analysis of events.
