Supermarket employees have been the hidden key workers of the past year, keeping shelves stocked and queues under control as panic buying gripped the nation. As a result of being expected to enforce face covering and social distancing regulations, they also been asked to act as de-facto security guards alongside their existing duties. This is problematic as many employees have never had to deal with this kind of responsibility before, let alone received any conflict de-escalation training. In order to maintain the safety and security of their staff retailers must take additional steps to uphold their duty of care, with the NPCC recently specifying that it is the responsibility of retailers ‘to manage entry to their stores and compliance with the law while customers are inside’. Supermarkets in particular need to be aware of this requirement, as the big four recently announced that their employees would now be challenging customers shopping in groups and those not wearing masks. Verbal abuse from the public Crime against retail employees has already been a major issue over the course of the pandemic, confirmed by research from the Union of Shop, Distributive and Allied Workers that found 90% of retail staff in the UK experienced verbal abuse last year. The Co-op has recently been vocal about the effects of the pandemic and lockdown-related frustrations on its employees.90% of retail staff in the UK experienced verbal abuse last year The supermarket reported a 140% increase in crime within its stores over the past year, with many of the 200,000 cases related to verbal and physical abuse experienced by employees. Jo Whitfield, Co-op Food chief executive, confirmed that the number of issues has already increased drastically as a result of staff enforcing COVID-secure guidelines. So, what steps must retailers take to ensure their duty of care remains intact as employees take on new enforcement responsibilities? Introducing real-time surveillance technology to support security guards and shop floor employees alike is vital. Bolstering front line defences Security guards posted at supermarket entrances are the first line of defence against shoppers determined to break the rules. However, they are now being pulled in multiple directions with queues to monitor and occupancy to manually keep track of, along with the usual security alarms to respond to. With one person usually posted at the entrance at any one time it’s simply impossible to have eyes everywhere, which is where automated video surveillance comes in. COVID-specific technologies, such as mask detection and occupancy management systems, are now the golden bullet to retail safety and security.Mask detection and occupancy management surveillance tools can automatically alert a shopper Mask detection and occupancy management surveillance tools can automatically alert a shopper whether or not they are allowed to enter the store on their approach to the door. The system surveys the person and a screen will automatically display different instructions depending on the situation: whether they must put a mask on before they enter, wait until capacity is low enough to enable social distancing or, if the previous criteria are fulfilled, that they are free to enter. COVID-secure safety This stand-off technology minimises the need for contact between security personnel and shoppers, allowing security guards to complete their usual duties, safe in the knowledge that the store is being managed in a COVID-secure way. With a hands-off approach enabled by surveillance technology, the potential for tense confrontation is greatly diminished as customers will usually comply to the reminder shown to them and put on a mask or wait without further prompting from staff. With security personnel able to better focus their attention on the stubborn rule-breakers,It is crucial that retailers choose a solution embedded in real-time connectivity this responsibility will no longer land with staff on the shop floor who are often ill-equipped to deal with this situation. It is crucial that retailers choose a solution embedded in real-time connectivity that will allow all store entrances to be screened simultaneously. Nobody can be in multiple places at once, but this connectivity allows alerts to be streamed instantly to any connected device that can be monitored by just one employee, meaning they can review the alerts that require their attention without needing to be physically present or re-tasked away from their day-to-day duties. Instant reassurance with body worn tech As a customer-facing role, there can be no guarantee that shop workers will never experience a potentially violent confrontation with a customer, which is where the presence of live streaming body worn cameras can help. While they may not always be trained to de-escalate a risky situation, being able to discreetly call for assistance can provide the reassurance employees need to feel safe and supported at all times. If an employee asks a customer to put a mask on while they’re in the store or step back from another shopper and the situation turns abusive – verbally or physically – a live streaming-enabled body worn camera can be triggered to stream a live audio and video feed back to a central control room manned by trained security personnel.A live streaming-enabled body worn camera can be triggered This real-time footage gives security staff exceptional situational awareness, allowing them to fully assess the situation and decide on the best course of action to support the employee in distress, whether that is going to the scene to diffuse the situation or contacting the police in more serious circumstances. Bolstering front line security This goes one step further than record-only body worn cameras, the capabilities of which these next generation devices match and exceed. Record-only cameras are well-suited to provide after-the-fact evidence if a customer interaction turns sour, but they do little to provide reassurance to out of depth employees in the moment. The duty of care grocery retailers must provide to their employees has never been more important, with staff taking on new mask and social distancing enforcement responsibilities and managing interactions with frustrated customers. Bolstering front line security and giving staff extra reassurances with the introduction of real-time video surveillance technology is a crucial step for retailers striving to keep employees and shoppers safe during these challenging times.
This year has been characterised by uncertainty and extraordinary strain, which has fallen heavily on all manner of key workers. Alongside our celebrated healthcare professionals, carers and the emergency services, those working in essential retail have proved themselves to be the backbone of our society during this challenging period. As people try to grasp onto normality and cope with the unexpected changes taking place in every aspect of their lives – including the way they are allowed to shop – it’s no surprise that tensions are now running higher than ever. Retail crime was already on the rise before the pandemic struck, with the British Retail Consortium finding that at least 424 violent or abusive incidents were reported every day last year. The Co-op recently reported its worst week in history in terms of abuse and antisocial behaviour, with 990 incidents of antisocial behaviour and verbal abuse suffered by staff between 20th and 26th July. 990 incidents of antisocial behaviour and verbal abuse suffered by staff between 20th and 26th July To manage the increased risks currently faced by retail employees, businesses must adopt new initiatives to safeguard their staff. Growing numbers of retailers including the Co-op and Asda have equipped their in-store and delivery staff with body worn cameras to enhance safety and provide them with peace of mind, as well as to discourage altercations from taking place at all. Traditional tech Body worn cameras are nothing new and have been used within the law enforcement industry for years. Traditional devices are record-only and can be used to record video evidence able to be drawn upon ‘after the fact’ should it be needed as an objective view of an event and who was involved. These devices can also be used to discourage violent or verbally abusive incidents from occurring in the first place. If a customer is approached by an employee, they are likely to think twice about retaliating if they know their interaction is being recorded. This stance is supported by research from the University of Cambridge that found the use of body worn cameras improves the behaviour of the wearer and those in its vicinity, as both are aware of the fact it can act as an objective ‘digital witness’ to the situation. However, record-only body worn cameras do leave much to be desired. In fact, the same University of Cambridge study found that, in the case of law enforcement, assaults against officers wearing these devices actually increased by 15%. This could be attributed to those being recorded being provoked by the presence of the camera or wanting to destroy any evidence it may hold. Out with the old, in with the new Live-streaming enabled body worn cameras provide the benefits of record-only devices and more Fortunately, there is a better option. Live-streaming enabled body worn cameras provide the benefits of record-only devices and more. Live-streaming capabilities are able to take ‘after the fact’ evidence one step further and provide the wearer with ‘in the moment’ safety and reassurance. With these devices, if a retail employee is subject to a volatile situation with a customer, they can trigger live video to be streamed back to a central command and control room where security officers will be able to take the most appropriate course of action with heightened and real-time situational awareness. Having access to all of the information they could need instantly will enable security personnel to decide whether to attend the scene and diffuse the situation themselves or to take more drastic action if needed, before any harm has been caused. This capability is especially valuable for lone workers who don’t have access to instant support – such as delivery drivers, in-store or warehouse staff and distribution operators to name a few. The pandemic has also doubled the number of consumers who do their regular grocery shopping online, leading to potential supply and demand issues resulting in unhappy customers. Live-streaming body worn cameras rely on uninterrupted mobile connectivity to excel, as they are not connected to any physical infrastructure. To minimise the risk of the live video stream buffering or freezing – a real possibility for delivery drivers who can be working anywhere in the country – retailers should look to deploy devices capable of streaming in real-time, with near zero latency footage, even when streaming over poor or constrained networks. To get the most out of their tech, retailers should also look to implement devices that can be multi-use and can be deployed as a body worn camera or a dashcam to record any incidents that may occur whilst driving. Novel threats This year brought about a new threat that retailers must protect their staff from While not to the same extent, retail workers have always been subject to a level of potential physical or verbal abuse. However, this year brought about a new threat that retailers must protect their staff from. The COVID-19 pandemic has been the cause of many of the new threats facing employees, but is also a threat in itself. To mitigate this, retailers should look to introduce remote elevated temperature detection cameras in their stores, which analyse body temperature and sound an alarm when somebody’s temperature exceeds a certain threshold – as this could indicate the presence of a potential fever. When deployed on the same cellular network as live-streaming enabled body cameras, these tools can be linked to a central command centre and the alarms viewed remotely from any connected device. This means a network of cameras can be monitored efficiently from a single platform. Ensuring the protection and security of retail workers has come to the fore this year. With the risk of infection in high-footfall locations, such as supermarkets, and the added pressure that comes with monitoring and enforcing safety guidelines, retail staff are having to cope with a plethora of new challenges. Retailers should adopt innovative technologies within their stores and delivery trucks, such as live-streaming enabled body cameras and remote elevated temperature screening solutions, to minimise the threat faced by their employees and provide them with instant support and reassurance should it be required.
Technology has played a vital role in how businesses have enabled their employees to work productively from home during the COVID-19 pandemic. For those of us who can do our jobs from home you only have to look at the ‘Zoom Boom’ to see how much our working lives have changed compared to the beginning of the year. Despite the fact that those companies that can are now productively and efficiently operating remotely, the country is now facing the next challenge in this crisis: how to safely reopen workplaces for those who can’t. There is no argument that the economy hasn’t taken a hit during this unpredictable time. Shops, restaurants and entertainment facilities have been forced to close, and 23% of the country’s workforce (6.3 million people) has been furloughed. It’s no surprise that the Bank of England has warned that the UK is heading towards its sharpest recession on record. To counter this economic risk, the government is taking steps to slowly and cautiously reopen the economy by easing lockdown measures, sending people back to work and allowing businesses to reopen. With non-essential retail outlets now able to open from the 15th June, the question business owners face is how to operate safely and maintain social distancing practices, which are set to remain in place until such time as a vaccine is widely available. With lockdown easing and a ‘new normal’ on the horizon, the health of the country’s workforce mustn’t be forgotten in a bid to save the economy. This is why technology that can allow for a controlled return to work, while mitigating any risks to the health of consumers and employees, must play a part in the easing of lockdown. Temperature screening in the new normal Elevated temperature screening is one technology that should play a key part in return to work strategies and the safe reopening of businesses. This valuable solution uses a thermal and optical camera to analyse body temperature, which is a key indicator of the presence of a potential illness, and discreetly alerts the operator when the set temperature threshold is exceeded by someone screened by the tool. With temperature screening technology in place, the exposure of potentially infected individuals to others can be dramatically decreased and the risk of a localised outbreak minimised. Furthermore, for businesses such as retailers whose success is dependent on customers feeling safe to visit the premises, it has the added benefit of giving them additional assurances that visible measures for their protection are in place. In combination with other solutions, such as vigorous testing and screens to protect employees and customers, returning to work can be safe and controlled. With temperature screening technology in place, the exposure of potentially infected individuals to others can be dramatically decreased The reality of a ‘new normal’ may already be visible in some industries, such as grocery retail where one-way systems, plastic screens and constant cleaning are already in place. However, elevated temperature screening has countless applications for both essential and non-essential industries, ranging from offices and train stations, to hospitals and pharmacies. This screening technology allows businesses to take preventative steps to minimise the chances of the wider workforce and customers coming into contact with someone exhibiting symptoms of a potential illness. A number of businesses are already deploying this technology, such as Vodafone, which has deployed heat detection cameras at key UK sites to protect its employees. The camera used by the telco can screen up to eight people at once and 100 people per minute, while judging body temperature in less than half a second – all of which makes it ideal for congested and high traffic areas. Not all solutions are created equal Over the past few months, we have been inundated with images and videos of temperature screening taking place within key industries, which have continued to operate through the pandemic. However, the hand-held thermometers commonly being used require the device to be within an extremely short range of the subject and are only able to screen one person at a time. This is why remote elevated temperature screening solutions are so valuable – especially given that social distancing guidelines are unlikely to be relaxed in the near future. Stand-off solutions can enable temperature screening to take place without the need for close human interaction, further safeguarding employees and reducing the risk of contact with potentially infected individuals. Elevated temperature screening has countless applications for both essential and non-essential industries, ranging from offices and train stations, to hospitals and pharmacies Along with remote capabilities, there are a number of other crucial factors to take into account. The solution must be quick and easy to implement, as well as being highly accurate. When paired with a blackbody, the accuracy of temperature screening solutions can be within 0.3°C. Connectivity is also key and adopting an end-to-end solution linked to a centralised command and control location is invaluable. With holistic connectivity, these solutions can encompass cameras installed in multiple locations, and alarms can be viewed locally, remotely or on a smartphone app. This means that staff don’t need to provide direct supervision to the device on-site. With the guidelines regarding which industries and sectors can reopen changing on an almost daily basis, it’s important that these protective solutions can be installed without overhauling the surveillance infrastructure already in place. Looking ahead, adopting a solution with an upgrade path to other enhancements, such a facial recognition, is favourable as they can be used in conjunction with future and existing security measures. Shop local Stand-off solutions can enable temperature screening to take place without the need for close human interaction Businesses have plenty on their minds as they prepare for the uncertainty that is sure to continue throughout the rest of the year and beyond. However, due diligence can’t be left to the wayside when looking to adopt an elevated temperature screening solution. There are high-risk vendors present in the market, many of which have been blacklisted in the US, and they must be given a wide berth. Buying British-made technology can alleviate these security concerns, as well as avoiding any logistical issues caused by the breakdown of global supply chains. As the economy cautiously reopens, the country will have to adapt to a ‘new normal’ over the coming months. Elevated temperature screening solutions should be implemented by businesses to protect the health of the workforce and customers alike – ultimately paving the way to a safe and controlled return to work.
The term “smart city” gets thrown around a lot nowadays, but as different technologies that strive to be defined in this way are adopted by different countries globally, the meaning of this phrase gets lost in translation. The simplest way to define a “smart city” is that it is an urban area that uses different types of data collecting sensors to manage assets and resources efficiently. One of the most obvious types of “data collecting sensor” is the video camera, whether that camera is part of a city’s existing CCTV infrastructure, a camera in a shopping centre or even a police car’s dash camera. The information gathered by video cameras can be used with two purposes in mind, firstly: making people’s lives more efficient, for example by managing traffic, and secondly (and arguably more importantly): making people’s lives safer. Live streaming video all the time, everywhere In the smart and safe city, traditional record-only video cameras are of limited use. Yes, they can be used to collect video which can be used for evidence after a crime has taken place, but there is no way that this technology could help divert cars away from an accident to avoid traffic building up, or prevent a crime from taking place in the first place. However, streaming live video from a camera that isn’t connected to an infrastructure via costly fibre optic cabling has proven challenging for security professionals, law enforcement and city planners alike. This is because it isn’t viable to transmit video reliably over cellular networks, in contrast to simply receiving it. Video transmission challenges Transmitting video normally results in freezing and buffering issues which can hinder efforts to fight crime and enable flow within a city, as these services require real-time, zero latency video without delays. Therefore, special technology is required that copes with poor and varying bandwidths to allow a real-time view of any scene where cameras are present to support immediate decision making and smart city processes. The information gatheredby video cameras can beused to make people’s lives more efficient, and to make people’s lives safer There are many approaches to transmitting video over cellular. We’ve developed a specialist codec (encoding and decoding algorithm) that can provide secure and reliable video over ultra-low bandwidths and can therefore cope when networks become constrained. Another technique, which is particularly useful if streaming video from police body worn cameras or dash cams that move around, is to create a local wireless “bubble” at the scene, using Wi-Fi or mesh radio systems to provide local high-bandwidth communications that can communicate with a central location via cellular or even satellite communications. Enhanced city surveillance Live video streaming within the smart and safe city’s infrastructure means that video’s capabilities can go beyond simple evidence recording and evolve into a tool that allows operations teams to monitor and remediate against incidents as they are happening. This can be taken one step further with the deployment of facial recognition via live streaming video. Facial recognition technology can be added on to any video surveillance camera that is recording at a high enough quality to identify faces. The technology works by capturing video, streaming the live video back to a control centre and matching faces against any watch lists that the control centre owns. Importantly, the data of people who aren’t on watch lists is not stored by the technology. Identifying known criminals This technology can work to make the city safer in a number of ways. For example, facial recognition could spot a known drug dealer in a city centre where they weren’t supposed to be, or facial recognition could identify if a group of known terror suspects were visiting the same location at the same time, and this would send an alert to the police. Facial recognition technology captures and streams live back to a control centre, matching faces against any watch lists that the control centre owns In an ideal world where the police had an automated, electronic workflow, the police officer nearest to the location of the incident would be identified by GPS and would be told by the control room where to go and what to do. Most police forces aren’t quite at this technological level yet, and would probably rely on communicating via radio in order to send the nearest response team to the scene. As well as this, shopping centres could create a database from analogue records of known shoplifters to identify criminals as soon as they entered the building. This would be even more effective if run co-operatively between all shopping centres and local businesses in an area, and would not only catch any known shoplifters acting suspiciously, but would act as a deterrent from shoplifting in the first place. Live streaming for police As mentioned above, live streaming video from CCTV cameras can help the police fight crime more proactively rather than reactively. This can be enhanced even further if combined with live streaming video from police car dash cams and police body worn cameras. If video was streamed from all of these sources to a central HQ, such as a police operations centre, the force would be able to have full situational awareness throughout an incident. This would mean that, if need be, officers could be advised on the best course of action, and additional police or other emergency services could be deployed instantly if needed. Incorporated with facial recognition, this would also mean that police could instantly identify if they were dealing with known criminals or terrorists. Whilst they would still have to confirm the identity of the person with questioning or by checking their identification, this is still more streamlined than describing what a person looks like over a radio and then ops trying to manually identify if the person is on a watch list. The smart, safe city is possible today – for one, if live video streaming capabilities are deployed they can enable new levels of flow in the city. With the addition of facial recognition, cities will be safer than ever before and law enforcement and security teams will be able to proactively stop crime before it happens by deterring criminal activity from taking place at all.
Digital Barriers, a globally renowned provider of edge-intelligent surveillance and security technologies, reveals its collaboration with the Future Farms Cymru project, run by North Wales Police. Real-time surveillance solutions Digital Barriers has equipped a farm in North Wales with its real-time surveillance solutions, to demonstrate the role that sophisticated technologies can play in cutting the cost of rural crime, estimated by the National Farmers Union to have reached 54 million pounds in 2019. Rural areas and farmland can be inherently difficult environments to secure. However, Digital Barriers’ scalable and flexible solutions are designed to work in demanding conditions, such as remote and vulnerable locations. AI-based edge analytics Digital Barriers’ video streaming capability and AI-based edge analytics can provide reliable and secure monitoring Proven and trusted within the military and defence domain, Digital Barriers’ state-of-the-art video streaming capability and AI-based edge analytics can provide reliable and secure monitoring, thereby protecting people, places and assets. The first technology being showcased as part of Future Farms Cymru project is a live streaming body worn camera for the enhanced protection of lone workers. If an incident occurs, the wearer can press the urgent assistance button, which transmits video and a live GPS location back to a designated monitoring centre, providing immediate response. EdgeVis Shield The second is EdgeVis Shield, a combination of easy-to-deploy ground sensors that can be used to secure vast perimeters, including farmland containing high value assets. The autonomous system automatically detects when irregular behaviour occurs around a perimeter, sending alerts and live video, if a trespasser or vehicle approaches. PC Dewi Evans of the North Wales Police Rural Crime Team commented on the announcement, “In recent years, we are increasingly seeing rural communities and businesses being targeted by criminals. Therefore, it is vital that rural businesses employ the right security methods to protect their assets. Criminals need to know that the farm they’re targeting could be equipped with this cutting-edge technology and they will be almost certainly caught.” Countering rise in rural crime Neil Hendry, Vice President EMEA at Digital Barriers, said, “I am happy that our technology is being used on the front line in the fight against rural crime. The COVID-19 pandemic has adversely affected businesses of all shapes and sizes, with farmers struggling to protect themselves against criminal activity.” Neil Hendry adds, “Future Farms Cymru is an important initiative, and we are delighted to be able help shape and support the future food and farming policy, with our robust video surveillance technology.”
The COVID-19 global pandemic continues, and more and more companies are looking for ways to continue (or resume) operations while minimising the coronavirus’s negative impact on their workforce, or potentially contributing to disease spread among the wider population. Thermal cameras have been proposed as a solution to screen individuals for elevated body temperature since the beginning of the pandemic. However, the technology has its detractors, and there are regulatory questions. We asked this week’s Expert Panel Roundtable: how can thermal cameras be used effectively for fever detection to screen for infectious diseases?
