Where are video surveillance cameras headed? At the core of next-generation Internet Protocol (IP) cameras are advanced chips with artificial intelligence (AI) at the edge, enabling cameras to gather valuable information about an incident: scanning shoppers at a department store, monitoring city streets, or checking on an elderly loved one at home.

Thanks to advanced chip technology, complex analytics operations are becoming more affordable across the full spectrum of surveillance cameras —professional to consumer — fueling the democratisation of AI in the IP camera market.

Expanding the global IP camera market 

The video surveillance equipment market grew to $18.5 billion in 2018 and is expected to increase this year, according to IHS Markit. The latest research points to video everywhere, edge computing, and AI as the top technologies that will have a major impact in both commercial and consumer markets in 2019.

Computing at the edge means that the processors inside the camera are powerful enough to run AI processing locally, while still encoding and streaming video, and are able to do it all at the low-power required to fit into the limited thermal budget of an IP camera. New SoC chips will be able to perform all of the processing on camera and provide accurate AI information, with no need to send data to a server or the cloud for processing.

Instead, data can be analysed right in the camera itself, offering high performance, real-time video analytics, and lower latency — all critical aspects of video surveillance. This new AI paradigm is made possible by a new generation of SoCs, a key driver behind the market growth of IP cameras.

Micro-processor-enabled video analytics

Next-generation video cameras will be able to create heat maps of stores to see where people spend the most time Microprocessor-enabled analytics allow users to more easily extract valuable data from video streams. How about an insider’s view into retail customer behavior? Consider video cameras at a department store, monitoring shoppers’ behavior, traffic patterns, and areas of interest. Next-generation cameras will recognise how long a shopper stays in front of a specific display, if the shopper leaves and returns, and if the shopper ultimately makes a purchase.

Next-generation video cameras will be able to create heat maps of stores to see where people spend the most time, so retailers will be able to adjust product placement accordingly. Analytics will also help identify busy/quiet times of the day, so retailers can staff accordingly. By understanding customers’ behavior, retailers can determine the best way to interact with them, target specific campaigns, and tailor ads for them. Cue the coupons while the shopper is still onsite!

Fast processing for rapid response at city level

City surveillance and smart cities are depending on advanced video surveillance and intelligence to keep an eye on people and vehicles, identify criminals, flag suspicious behavior, and identify potentially dangerous situations such as loitering, big crowds forming, or cars driving the wrong way.Quick local decisions on the video cameras are also used to help analyse traffic situations

Quick local decisions on the video cameras are also used to help analyse traffic situations, adjust traffic lights, identify license plates, automatically charge cars for parking, find a missing car across a city, or create live and accurate traffic maps.

Real-time HD video monitoring and recording

When it comes to home monitoring, what will next-generation video surveillance cameras offer? Real-time monitoring and notification can detect if a person is in the back yard or approaching the door, if there’s a suspicious vehicle in the driveway, or if a package is being delivered (or stolen). Advanced video cameras can determine when notifications are and aren’t required, since users don’t want to be notified for false alerts such as rain, tree branches moving, bugs, etc.

Next-generation video camera capabilities can also help monitor a loved one, person or pet, helping put families at ease if they are at work or on vacation. For example, helpful analytics may be used to detect if someone has fallen, hasn’t moved for a while, or does not appear for breakfast according to their typical schedule.

Next-gen IP cameras

When evaluating next-generation IP cameras (cameras on the edge), look at the brains. These cameras will likely be powered by next-generation SoCs chips. Here is what this means to you:      

  • Save on network bandwidth, cloud computing and storage costs. There is no need to constantly upload videos to a server for analysis. Analysis can be performed locally on the camera, with only relevant videos being uploaded.
  • Faster reaction time. Decisions are made locally, with no network latency. This is critical if you need to sound an alarm on a specific event.
  • Privacy. In the most extreme cases, no video needs to leave the camera. Only metadata needs to be sent to the cloud or server. For example, the faces of people can be recognised in the camera and acted upon, but the video never reaches the cloud. The cameras can just stream a description of the scene to the server “suspicious person with a red sweater walking in front of the train station, has been loitering for the last 10 minutes, suggest sending an agent to check it out.” This could become a requirement in some EU countries with GDPR rules.
  • Easier search. Instead of having to look through hours of video content, the server can just store/analyse the metadata, and easily perform searches such as “find all people with a red sweater who stayed more than five minutes in front of the train station today.”
  • Flexibility/personalisation. Each camera at the edge can be personalised to work better for the specific scene it is looking at, compared to a generic server. For example, “run a heat map algorithm on camera A (retail) as I want to know which sections of my store get the most traffic; and run a license plate recogniser on camera B (parking lot) as I want to be able to track the cars going in/out of my parking lot.”
  • No cloud computing required. For cameras in remote locations or with limited network bandwidth, users have the ability to perform all analytics locally, without relying on uploading video to a server/cloud.
  • Higher resolution/quality. When AI processing is performed locally, the full resolution of the sensor can be used (up to 4K or more), while typically the video streamed to a server will be lower resolution, 1080p or less. This means more pixels are available locally for the AI engine so that you will be able to detect a face from a higher distance than when the video is streamed off camera.

AI at the edge

Professional-level IP cameras capable of performing AI at the edge are coming soon with early offerings making their debut at this year’s ISC West. As we enter 2020, we will begin to see the availability of consumer-level cameras enabling real-time video analytics at the edge for home use. With rapid technology advancement and increased customer demand, AI is on the verge of exploding. When it comes to image quality and video analytics, IP cameras now in development will create a next-generation impact at department stores, above city streets, and keeping an eye on our loved ones.

Managing security during unprecedented times of home working
Managing security during unprecedented times of home working

Companies are following government guidance and getting as many people as possible working from home. Some companies will have resisted home working in the past, but I’m certain that the sceptics will find that people can be productive with the right tools no matter where they are. A temporary solution will become permanent. But getting it right means managing risk. Access is king In a typical office with an on-premise data centre, the IT department has complete control over network access, internal networks, data, and applications. The remote worker, on the other hand, is mobile. He or she can work from anywhere using a VPN. Until just recently this will have been from somewhere like a local coffee shop, possibly using a wireless network to access the company network and essential applications. CV-19 means that huge numbers of people are getting access to the same desktop and files, and collaborative communication toolsBut as we know, CV-19 means that huge numbers of people are getting access to the same desktop and files, applications and collaborative communication tools that they do on a regular basis from the office or on the train. Indeed, the new generation of video conferencing technologies come very close to providing an “almost there” feeling. Hackers lie in wait Hackers are waiting for a wrong move amongst the panic, and they will look for ways to compromise critical servers. Less than a month ago, we emerged from a period of chaos. For months hackers had been exploiting a vulnerability in VPN products from Pulse Secure, Fortinet, Palo Alto Networks, and Citrix. Patches were provided by vendors, and either companies applied the patch or withdrew remote access. As a result, the problem of attacks died back.  But as companies race to get people working from home, they must ensure special care is taken to ensure the patches are done before switching VPNs on. That’s because remote desktop protocol (RDP) has been for the most part of 2019, and continues to be, the most important attack vector for ransomware. Managing a ransomware attack on top of everything else would certainly give you sleepless nights. As companies race to get people working from home, they must ensure special care is taken to ensure the patches are done before switching VPNs on Hackers are waiting for a wrong move amongst the panic, and they will look for ways to compromise critical serversExposing new services makes them also susceptible to denial of service attacks. Such attacks create large volumes of fake traffic to saturate the available capacity of the internet connection. They can also be used to attack the intricacies of the VPN protocol. A flow as little as 1Mbps can perturbate the VPN service and knock it offline. CIOs, therefore, need to acknowledge that introducing or extending home working broadens the attack surface. So now more than ever it’s vital to adapt risk models. You can’t roll out new services with an emphasis on access and usability and not consider security. You simply won’t survive otherwise. Social engineering Aside from securing VPNs, what else should CIO and CTOs be doing to ensure security? The first thing to do is to look at employee behaviour, starting with passwords. It’s highly recommended that strong password hygiene or some form of multi-factor authentication (MFA) is imposed. Best practice would be to get all employees to reset their passwords as they connect remotely and force them to choose a new password that complies with strong password complexity guidelines.  As we know, people have a habit of reusing their passwords for one or more online services – services that might have fallen victim to a breach. Hackers will happily It’s highly recommended that strong password hygiene or some form of multi-factor authentication (MFA) is imposedleverage these breaches because it is such easy and rich pickings. Secondly, the inherent fear of the virus makes for perfect conditions for hackers. Sadly, a lot of phishing campaigns are already luring people in with the promise of important or breaking information on COVID-19. In the UK alone, coronavirus scams cost victims over £800,000 in February 2020. A staggering number that can only go up. That’s why CIOs need to remind everyone in the company of the risks of clickbait and comment spamming - the most popular and obvious bot techniques for infiltrating a network. Notorious hacking attempts And as any security specialist will tell you, some people have no ethics and will exploit the horrendous repercussions of CV-19. In January we saw just how unscrupulous hackers are when they started leveraging public fear of the virus to spread the notorious Emotet malware. Emotet, first detected in 2014, is a banking trojan that primarily spreads through ‘malspam’ and attempts to sneak into computers to steal sensitive and private information. In addition, in early February the Maze ransomware crippled more than 230 workstations of the New Jersey Medical Diagnostics Lab and when they refused to pay, the vicious attackers leaked 9.5GB or research data in an attempt to force negotiations. And in March, an elite hacking group tried to breach the World Health Organization (WHO). It was just one of the many attempts on WHO and healthcare organisations in general since the pandemic broke. We’ll see lots more opportunist attacks like this in the coming months.   More speed less haste In March, an elite hacking group tried to breach the World Health Organization (WHO). It was just one of the many attempts on WHOFinally, we also have bots to contend with. We’ve yet to see reports of fake news content generated by machines, but we know there’s a high probability it will happen. Spambots are already creating pharmaceutical spam campaigns thriving on the buying behaviour of people in times of fear from infection. Using comment spamming – where comments are tactically placed in the comments following an update or news story - the bots take advantage of the popularity of the Google search term ‘Coronavirus’ to increase the visibility and ranking of sites and products in search results. There is clearly much for CIOs to think about, but it is possible to secure a network by applying some well thought through tactics. I believe it comes down to having a ‘more speed, less haste’ approach to rolling out, scaling up and integrating technologies for home working, but above all, it should be mixed with an employee education programme. As in reality, great technology and a coherent security strategy will never work if it is undermined by the poor practices of employees.

Security technology and AI: A powerful duo in the fight against COVID-19
Security technology and AI: A powerful duo in the fight against COVID-19

A person infected with the Coronavirus (COVID-19) infects an average of 2.5 other people within five days. You do not need to be a mathematician to realise that early detection of infected people is key to successful pandemic containment. The aim of effective containment strategies is therefore not so much to reduce the number of absolute cases as it is to extend the time frame within which they occur. Without effective containment measures, the virus spreads rapidly and is beyond the capacity of the health care system. However, if infection rates can be minimised through early detection and rapid, targeted identification of further infections, cases will continue to occur over a longer period of time and remain within the capacity of the health care system. Identifying, testing and results For example, the goal of many countries is to carry out as many Corona tests as possible to quickly identify infected people. It is then necessary to identify and reach potentially-infected people and isolate them in quarantine. This is a tried and tested procedure. But this method also costs valuable time in the fight against the virus and has many unknowns. The determination of a concrete test result alone sometimes takes up to 48 hours due to limited laboratory capacity. Added to this is the imprecise and slow procedure for determining contact persons. Or do you still remember exactly who and where you shook hands with in the last ten days - and could you provide information on this? Security technology to the rescue When it comes to the time factor, security technology can be a great help. Thermal imaging cameras and temperature sensors, for example, can help to detect a person with elevated body temperatures. Fever can also be one of the symptoms in those infected with the Coronavirus. At neuralgic points such as airports and train stations, or at entrances to hospitals, thermal imaging cameras can quickly reveal which people have fever. Presumably infected people can be easily separated and asked about other symptoms. Physical security technology can make a great contribution here. Dr. Frank Gillert, a professor at the University of Applied Sciences in Wildau, Germany states, however, as one of the leading scientists for logistics-centric security research, he demands "rapid innovation in dealing with situations like COVID-19 should be a priority". He sees enormous potential in the possibilities of IT and artificial intelligence; "We should use the disruptive changes that are currently taking place and that are challenging global orders to strengthen the significance in IT infrastructure development and also in security technology development.“ The goal in a global crisis And he is right: In global crises such as the Corona pandemic, security-related deficits become apparent and space is created for technical innovations. The goal of governments and companies is to restore security and save human lives as quickly as possible. The German data analytics powerhouse G2K, for example, has developed a Corona Detection & Containment System (CDCS) that is ready for immediate use in record time. Detection takes place in combination with AI-supported data analysis to specifically identify virus hotspots and distribution routes, as well as to identify other potentially infected persons. When developing the system, the focus was on two questions: How do I detect a suspected infected person in crowded environments and even more importantly, how do I quickly and comprehensively determine the person's contacts and previous whereabouts, and find correlations and patterns in this information? The data experts of the Berlin-based company found the answer in the combination of physical security technology and their existing data analytics platform. The G2K system The system is based on G2K's scalable IoT platform "Situational Awareness Builder" (SAB), which is already in use in several projects worldwide and sets standards in process automation and process optimisation, including security management. As soon as a person with fever is detected by the system, he or she can be immediately screened to avoid contact with other people and thus prevent possible new infections, i.e. to interrupt the chain of infection. For this purpose, stationary thermal imaging cameras or smartphones equipped with a temperature sensor accessory can be used. The potentially infected person must now be registered and referred to a doctor or hospital for further specific diagnostic measures. The entire process is covered by a mobile G2K application. A combination of security and medicine The platform can bring together available hospital capacity, infection reports, movement and contact profiles and provide an excellent picture of the source of infection. Thus, medically necessary isolations can be implemented quickly. At the same time, infected patients can use the app to document their recovery and become actively involved. All this data is centrally managed and analysed, using deep learning methods. This provides crisis managers with a single monitoring, control and resource management tool that enables immediate action to be taken to combat the spread of the virus and gives officials full transparency on the status of the pandemic. Karsten Neugebauer, founder and CEO of the company behind the solution, explains his commitment as follows "A few weeks ago we too were faced with increasing difficulties due to the Corona crisis. As we have a strong presence in Europe in particular, we had to struggle with postponed project starts and limited resources". But instead of burying their heads in the sand, G2K's dedicated team decided to declare war on the virus." "In our entrepreneurial duty, we, therefore, decided to use our available technology and equip it to fight COVID-19. Our team has been working day and night over the last few weeks to expand our software platform to enable us to contain the pandemic quickly and effectively. Politicians must now immediately push ahead with the unbureaucratic implementation of prevention and control measures such as our CDCS to ensure the stability of our public systems," demands Karsten Neugebauer. The pandemic continues As the COVID-19 pandemic spreads from continent to continent, researchers around the world are working to develop antidotes to the virus. As long as this has not been found, the spread of the virus must be slowed down internationally. Only by this can system-relevant infrastructure be held consistently. Combining modern physical security technology with platform technology and artificial intelligence provides an excellent possibility to slow down the current and for sure, future pandemics.

Emergency response and notification systems: Crucial for improving hospital security
Emergency response and notification systems: Crucial for improving hospital security

When violence or a life-threatening incident occurs, hospitals and other healthcare institutions are often in the crosshairs. Hospitals increasingly face a reality of workplace violence, attacks on patients, and threats to doctors and other support staff. And even if violence happens outside a hospital – such as an active shooter at a public place – the local hospital must be prepared to respond to an influx of injured victims. When conflicts arise inside a hospital, there is an urgent need to lock the facility down quickly. Security professionals and their teams need access control options that allow lockdowns to occur at the touch of a button. Lockdown capabilities are an important aspect of safety and security for hospitals, doctor’s offices and medical facilities The need for mass notification is also growing in the healthcare environment Fire alarm public address system The need for mass notification – another aspect of responding in an emergency – is also growing in the healthcare environment. Various systems can communicate through the fire alarm public address (PA) system to notify people in an emergency, or, alternately, to use email notification, text messaging, pagers, smart phones and/or personal computers (PCs). In lockdown situations, access control systems provide an emergency button with various triggers in the system – a hospital can lockdown specific units or the entire facility. Data capture form to appear here! Jim Stankevich, Global Manager – Healthcare Security, Johnson Controls/Tyco Security Products, points out that the safety of hospital staff, particularly nurses, cannot be overlooked. In the emergency room, 55 percent of nurses are assaulted in some way each year, which is a high percentage. The safety of nurses and all hospital staff deserves more attention. Duress/emergency notification technology Stankevich says one solution is to use duress/emergency notification technology: staff can carry and wear a ‘panic button” or have a two-key combination on their computer as an alarm trigger. When the staff member hits the panic button, a direct message can be sent to security, alerting security staff about the event and requiring a response. There has been an increase in demand for the safety and security of patients, staff and visitors at healthcare institutions, as evidenced by the recent CMS (Centers for Medicare and Medicaid Services) Emergency Preparedness Rule. As of Nov. 17, 2017, healthcare institutions that participate in Medicare or Medicaid must demonstrate compliance with the rule. Emergency preparedness systems A major challenge in compliance to this rule is balancing patient safety with comfort At its core, the rule seeks to establish national emergency preparedness requirements to ensure adequate planning for both natural and man-made disasters, and coordination with federal, state, tribal, regional and local emergency preparedness systems. A major challenge in compliance to this rule is balancing patient safety with comfort. Institutions should consider two-way communication that enables leadership to disseminate targeted messages quickly and efficiently, while arming all employees with a tool that can alert the appropriate staff should an incident occur. Solutions like this enable swift communication of issues without disturbing patients and visitors unless necessary. Effective response to emergencies “Fortunately, hospitals and their security departments are generally well equipped to respond to most emergency situations”, said John M. White, president/CEO of Protection Management, a consultant who works with hospitals to address their security needs. During the Ebola scare in 2014, however, hospitals had to re-examine their plans to ensure they were prepared to meet the challenges specific to rare and deadly disease. “Hospitals are prepared for most things, but Ebola seemed to have caught the whole world off guard, so people responded in different ways,” says White, who previously was security director of two multi-campus medical facilities before becoming a consultant. Hospital security Hospitals made adjustments to their emergency programs to determine how best to handle Ebola patients" He adds, “Hospitals made adjustments to their emergency programs to determine how best to handle Ebola patients and to protect other patients and staff. It was a new threat that healthcare organisations had not specifically addressed.” A particular concern was the possibility of an infected person walking into an emergency room and infecting other people and/or requiring facility decontamination. One role the hospital security department plays in such an emergency is to control access to the facility and to control visitors’ movements once they are inside the facility, says White. If the Ebola scare had progressed to the point that a hospital would need to screen patients, security would be positioned at the front entrance to help with that screening and, if necessary, to direct patients to a specific area for quarantine. Protective equipment Security might also need to wear protective equipment to handle a patient who is resistant to treatment, for example. There are often interactions between security personnel and the general public, a scenario that becomes more complicated if Ebola or a similar infection is likely. In general, security would be tasked with maintaining order and keeping people where they need to be, freeing up the medical professionals to do their jobs more efficiently, says White. To prepare for the impact of the Ebola scare, hospitals addressed various training and equipment needs and adjusted their disaster/emergency response plans.
