How Internet Of Things (IoT) Aids Facility Management And Physical Security
How Internet Of Things (IoT) Aids Facility Management And Physical Security

As buildings become more complex and smarter, the age-old traditional maintenance methods that are based mostly on hands-on human monitoring are becoming more and more inadequate. Instead, the world is fast adopting building automation as a key component of smarter and more proactive maintenance strategies. The aim is to free up maintenance staff and give them time to focus on other tasks while machines monitor the different systems that work together to make the facility functional. Specifically, Internet of Things - or, IoT - enablement appears set to transform the way facility managers deliver service to building occupants. The trends are many and the possibilities are almost mind-boggling, from inventory management, to work scheduling and energy efficiency, the list goes on and on. Below, we look at a few ways in which IoT is being used for Facility Management and Security. Revolutionize Maintenance Through Condition-Based Maintenance For years now, the norm among maintenance professionals has been a time-based approach, or in simpler terms, performing maintenance operations after a set period of time. But a major flaw of this system is that components were being replaced periodically whether the parts were actually worn out or not. Of course, that meant some of these maintenance activities simply weren’t cost-effective. To avoid this waste from continuing, a subset of IoT known as IIoT can now be used to optimize the maintenance process. IIoT works as a centralized network of connected systems and devices that can talk to one another and generate and relay data Rather than changing parts on a time-based schedule, IIoT works as a centralized network of connected systems and devices that can talk to one another and generate and relay data. Selected equipment are fitted with sensors that monitor specific operational parameters and let maintenance professionals know how the machines under supervision are working, understand their current condition, and then pinpoint the optimum time they need to be maintained. The information generated this way is vital as it allows maintenance staff to intervene just in time to avoid costly downtime and other associated inconveniences. This is, in a nutshell, the basics of predictive maintenance and condition-based maintenance. These days, by implementing condition-based maintenance, IIoT is being used to effectively monitor a wide range of systems such as lighting, HVAC, fire suppression, security, etc. The applications are numerous and so are the benefits. On page 52 of this guide by the US Department of Energy, they state that a functional predictive maintenance program could yield up to 10 times ROI, reduce maintenance costs by 25% to 30%, and reduce downtime by 35% to 45% Along with fire suppression, IIoT is effectively monitoring a wide range of systems such as lighting, HVAC and security Remote Monitoring Of Facilities Physical inspections have been a critical condition for the success of conventional maintenance programs, even in hazardous environments. But, with the increasing emphasis on personnel safety, organizations want alternative solutions that allow staff to examine assets without being physically present. Facility managers and their team working in industries like manufacturing, oil and gas, and mining can relate with these constraints. And these industries can benefit greatly from deploying predictive maintenance solutions. For example, in the oil and gas industry, IIoT sensors can be used to monitor remote and highly critical assets. These sensors can be used on pipelines to detect anomalies (especially corrosion) and pass that information to supervisors for necessary action. By doing this, potential failures are quickly predicted to avoid often disastrous incidents. Managing Energy Consumption Sensors are also being embedded in building components and devices like HVAC systems, lights, doors, windows to understand energy consumption and proactively manage it. Facilities that use this technology could achieve substantial energy savings. In a press release by IT research and advisory company, Gartner, they stated that IoT can help reduce the cost of energy - as well as spatial management and building maintenance - by up to 30%. Looking at HVAC systems very closely, we see that they are a major source of energy usage in any building These sensors work by monitoring different conditions in the building and causing a power-saving action based on the data received. For instance, occupancy sensors can order lights to turn on when it senses motion in a room and then turn off the same lights when there is no presence there. That way, there is no need to wait for someone to remember to switch off the lights when they are not needed.   Another very common use is in HVAC monitoring. Looking at HVAC systems very closely, we see that they are a major source of energy usage in any building. So, the issue is how can one use IIoT to manage HVAC and possibly reduce their energy usage? Well, in its most common form, IoT-enabled HVAC works as a connection of sensors and thermostats that monitor factors like indoor air quality, temperature, and environmental changes then communicate with the rest of the HVAC equipment and make needed adjustments for occupants’ comfort. Not only that. IoT-enabled HVAC works as a connection of sensors and thermostats that monitor factors like indoor air quality, temperature, and environmental changes The Technology Can Be Configured To: Track energy consumption at different distribution points throughout the building. Track usage from the power source right down to the consumption point. Detect sudden voltage drops or spikes (usually an indication of some fault). These are essential benefits because HVAC units are notorious for consuming large amounts of energy when they are working inefficiently. Security And Access Control Smart surveillance is another important area of application for IoT in facilities management. It takes several forms such as the monitoring of life-saving systems like intruder or fire alarms, invisible barriers, and other safety installations. Facility managers are using IoT across different industries to obtain live information about potential emergency situations with a view to responding before the issue escalates. In such cases, quick detection of any strange activity is key because many of these installations have tangible negative effects when they fail or when they are intentionally sabotaged.Smart surveillance is another important area of application for IoT in facilities management Fortunately, the surveillance equipment can also be setup to send alerts to cellphones to aid emergency response or evacuation as the case may be. Smart surveillance is also priceless for monitoring the situation in partially or fully automated remote facilities (especially oil and gas installations and mines), and in hostile environments with critical equipment where humans cannot work for extended periods of time. If you are not yet using IoT in your facility, you may be wondering where to start from. To avoid getting overwhelmed, a good place to start would be to try a small-scale deployment of this technology then review its ROI and impact on your operations before adopting a more widespread IoT implementation. This way you can gradually scale up as you and your staff come to understand and adapt and to this new way of doing things.

Data Security Experts At Bosch And Genetec Discuss Impact Of GDPR On Video Security
Data Security Experts At Bosch And Genetec Discuss Impact Of GDPR On Video Security

Today, more and more video security cameras are increasingly connected to the internet and transitioning into intelligent sensors that collect significantly more data than video security images alone. However, as this level of connectivity and collection of business-sensitive data becomes more widespread, the threat from cybercrime also rises. This is clearly an issue that affects everyone. After all, nobody is immune from cybercrime, not even the experts, which raises the question: What is the viewpoint of the experts when it comes to data security? Geoff Kohl, Senior Director of Marketing for the Security Industry Association, was keen to get the opinions of those who are experiencing the current situation with regard to data protection, and its impact on video security, first-hand. What follows is an outline of the discussion with Gregor Schlechtriem, Senior Vice President business unit Security of Bosch Building Technologies, a global player in video surveillance, and Pierre Racz, CEO of Genetec, who are world-renowned for their software in the safety and security domain. End-To-End Security System According to the experts, data security starts with an end-to-end solution The introduction of a key statistic started the conversation: by 2025, it is expected that 75 billion devices will be connected to the Internet. Clearly, this also impacts video security as it is no longer isolated and part of a ‘closed’ system; it has become part of the IoT. Therefore, the focus cannot remain solely on image quality and the reduction of bitrates; equal prominence must be given to data security. According to the experts, data security starts with an end-to-end solution. For example, the consequences of having an unprotected computer inside your firewall are immeasurable; it’s like an open door to cyber criminals. To successfully minimize the risks the complete video security infrastructure needs to be considered, rather than single components. This is a key advantage of an end-to-end security system that eliminates potential weak links. Secure Communication Between Trusted Devices So, end-to-end data security solutions have their advocates, but what makes them so persuasive, and effective? Well, solutions such as those developed by Bosch and Genetec are designed to safeguard communication between trusted devices, ensure that video in transit (streamed) or in storage remains encrypted and any commands and configurations to control cameras and other devices are transmitted via a secure channel (HTTPS). When one side questions the design of the other we accept that the observation is accurate" To achieve this effectively requires collaboration, which is why, according to Geoff Kohl, an ecosystem of trusted partners is invaluable, “Risk is not the responsibility of one company. Everyone has to be working together. Bosch and Genetec are obviously doing this.” To support Geoff’s opinion, Pierre Racz believes that trust is a quality to be earned, not bought. A case in point is the 15-year working relationship between Bosch and Genetec, “The engineers know each other. We have a trusted relationship, so when one side questions the design of the other we accept that the observation is accurate.” Management Of Massive Data In what ways can more focus be applied to data security? Although the basic task of video security systems remains unchanged, new technologies are consistently being introduced that offer new possibilities. An example of this is IP technology which, when combined with the increasing computation power, enables video security cameras to capture images of a quality that was previously unimaginable. GDPR instills an obligation to guarantee privacy by design According to Gregor Schlechtriem, “As the industry moves to delivering great image quality it creates new challenges, like how to intelligently manage the massive influx of data. On the other hand, video security devices connected to the internet and the wealth of their collective data is a fantastic enabler for new opportunities.”Video security has undergone substantial changes and offer limitless possibilities He is also of the opinion that video security data should be viewed as business tool that provides insights to improve efficiency, increase security or create new business opportunities. It is clear that, compared to the earlier days, other departments, like marketing, are getting more interested in video security data. Meanwhile, as CEO of Genetec, Pierre Racz confirms that video security has undergone substantial changes and offer limitless possibilities. The change to a digital (IP) infrastructure enables the use of video analytics that deliver metadata. This metadata adds sense and structure to video data and provides metrics such as speed, direction, color, size, object class and trajectory. The result of this enriched, more business-focused video data collection is a deeper level of business intelligence. Minimizing Risks Gregor Schlechtriem is only too aware that this level of connectivity also brings a higher level of risk, “Because there is valuable information included in videos we have to focus more on data security, and think beyond the basic tasks of a security system.” Pierre Racz agrees.A digital infrastructure and connectivity opens up countless opportunities The consequences of being hacked are clearly front of mind for him, “If we turn on the news today we can see the circus that has resulted from the global chaos caused by a recent cyber-breach.” By focusing on minimizing these risks, Pierre Racz believes that IoT and the technology enabling us to collect and interpret video data will outweigh the risks and provide improvements in health, and wealth. The key learning here is that a digital infrastructure and connectivity opens up countless opportunities, as expressed by Gregor Schlechtriem, “It is the enabler to generate valuable data for your business, to understand what’s going on with video analytics at the edge and derive invaluable data for situational awareness to improve your business. If you don’t use IP, you miss out.” The change to a digital (IP) infrastructure enables the use of video analytics that deliver metadata Operational Efficiency Pierre Racz agrees, “Compared to video cassettes we can provide so much more value with the kind of technology that can be initially utilized for security, but then leveraged for operational efficiency and even shared with other departments, such as marketing.” He also believes that, although the economic lifetime of analog equipment is almost double that of digital equipment, analog is a low pass filter, so image quality is limited to standards established in 1937. As Geoff concludes the interview and the various opinions are assessed, it’s clear that the end-to-end data security solutions such as those employed by Bosch and Genetec are the way forward for video data security. GDPR Influence Considering the recent changes in European regulations, Geoff Kohl of the Security Industry Association now invites invited Gregor Schlechtriem and Pierre Racz to briefly share their thoughts regarding GDPR – one of the first official data protection acts – and its impact on solutions and business models. If these regulations are applied to Facebook, the resultant penalty will be $1.6b"Pierre Racz highlights the recent Facebook case, “If these regulations are applied to Facebook, a technologically savvy company with $40b of revenue, the resultant penalty will be $1.6b. There is no better example of why data negligence and fiduciary irresponsibility is simply unacceptable.” Gregor Schlechtriem’s point of view is that GDPR instills an obligation to guarantee privacy by design, therefore it should influence any business model from the moment of conception. “You have to bring the right ingredients to the table to guarantee privacy, it’s the responsibility of the system owner. That’s why we analyzed our systems to ensure our technology was capable of meeting the requirements.” And, of course, trust. But the significance of this to people's everyday lives must also be considered; a sentiment which Pierre Racz captures perfectly, “Privacy is our democratic right.”

How To Choose The Right Storage Card For Video Surveillance Systems
How To Choose The Right Storage Card For Video Surveillance Systems

With increased demands being placed on safety and security globally, and supported by advancements in IP cameras and 360-degree camera technology, the video surveillance industry is growing steadily. Market research indicates that this worldwide industry is expected to reach an estimated $39.3 billion in revenue by 2023, driven by a CAGR of 9.3 percent from 2018 to 2023. Video surveillance is not just about capturing footage (to review an event or incident when it occurs), but also about data analysis delivering actionable insights that can improve operational efficiencies, better understand customer buying behaviors, or simply just provide added value and intelligence. Growth of Ultra-HD Surveillance To ensure that the quality of the data is good enough to extract the details required to drive these insights, surveillance cameras are technologically evolving as well, not only with expanded capabilities surrounding optical zoom and motion range,4K Ultra HD-compliant networked cameras are expected to grow from 0.4 percent shipped in 2017, to 28 percent in 2021 but also relating to improvements in signal-to-noise (S2N) ratios, light sensitivities (and the minimum illumination needed to produce usable images), wide dynamic ranges (WDR) for varying foreground and background illumination requirements, and of course, higher quality resolutions. As such, 4K Ultra HD-compliant networked cameras are expected to grow from 0.4 percent shipped in 2017, to 28 percent in 2021, representing an astonishing 170 percent growth per year, and will require three to six times the storage space of 1080p video dependent on the compression technology used. Surveillance cameras are typically connected to a networked video recorder (NVR) that acts as a gateway or local server, collecting data from the cameras and running video management software (VMS), as well as analytics. Capturing this data is dependent on the communications path between individual cameras and the NVR. If this connection is lost, whether intentional, unintentional, or a simple malfunction, surveillance video will no longer be captured and the system will cease operations. Therefore, it has become common to use microSD cards in surveillance cameras as a failsafe mechanism. Despite lost connectivity to the NVR, the camera can still record and capture raw footage locally until the network is restored, which in itself, could take a long time depending on maintenance staff or equipment availability, weather conditions, or other unplanned issues. Since microSD cards play a critical role as a failsafe mechanism to ensure service availability, it is important to choose the right card for capturing video footage.  It has become common to use microSD cards in surveillance cameras as a failsafe mechanism if an NVR breaks Key Characteristics Of microSDs There are many different microSD cards to choose from for video capture at the network’s edge, and they range from industrial grade capabilities to commercial or retail grade, and everything in-between. To help make some of these uncertainties a little more certain, here are the key microSD card characteristics for video camera capture. Designed For Surveillance As the market enjoys steady growth, storage vendors want to participate and have done so with a number of repurposed, repackaged, remarketed microSD cards targeted for video surveillance but with not much robustness, performance or capabilities specific to the application. Adding the absence of mean-time between failure (MTBF) specifications to the equation, microSD card reliability is typically a perceived measurement -- measured in hours of operation and relatively vague and hidden under metrics associated with the camera’s resolution and compression ratio. Therefore, when selecting a microSD card for surveillance cams at the edge, the choice should include a vendor that is trusted, has experience and a proven storage portfolio in video surveillance, and in microSD card technologies. Endurance, as it relates to microSD cards, represents the number of rewrites possible before the card can no longer store data correctly  High Endurance Endurance, as it relates to microSD cards, represents the number of rewrites (program/erase cycles) that are possible before the card can no longer store data correctly. The rewrite operation is cyclical whereby a new stream of footage replaces older content by writing over it until the card is full, and the cycle repeats. The higher the endurance, the longer the card will perform before it needs to be replaced. Endurance is also referred to in terabytes written (TBW) or by the number of hours that the card can record continuously (while overwriting data) before a failure will occur. Health Monitoring Health monitoring is a desired capability that not many microSD cards currently support and enables the host system to check when the endurance levels of a card are low and needs to be replaced. Having a card that supports this capability enables system integrators and operators with the ability to perform preemptive maintenance that will help to reduce system failures, as well as associated maintenance costs. Performance To capture continuous streams of raw footage, microSD cards within surveillance cams perform write operations about seventy to ninety percent of the time, whereas reading captured footage is performed about ten to thirty percent. The difference in read/write performance is dependent on whether the card is used in an artificial intelligent (AI) capable camera, or a standard one.   microSD cards deployed within surveillance cameras should support temperature ranges from -25 degrees Celsius to 85 degrees Celsius Finding a card that is write-friendly, and can provide enough bandwidth to properly capture streamed data, and is cost-effective, requires one that falls between fast industrial card capabilities and slower commercial ones. Bandwidth in the range of 50 MB/sec for writes and 80 MB/sec for reads are typical and sufficient for microSD cards deployed within surveillance cameras. Temperature Ranges Lower capacity support of 32GB can provide room to attract the smaller or entry-level video surveillance deployments As microSD cards must be designed for continuous operation in extreme weather conditions and a variety of climates, whether located indoors or out, support for various temperature ranges are another consideration. Given the wide spectrum of temperatures required by the camera makers, microSD cards deployed within surveillance cameras should support temperature ranges from -25 degrees Celsius to 85 degrees Celsius, or in extreme cases, as low as -40 degrees Celsius. Capacity Selecting the right-sized capacity is also very important as there needs to be a minimum level to ensure that there is enough room to hold footage for a number of days or weeks before it is overwritten or the connectivity to the NVR is restored. Though 64GB is considered the capacity sweet spot for microSD cards deployed within surveillance cameras today, lower capacity support of 32GB can provide room to attract the smaller or entry-level video surveillance deployments. In the future, even higher capacities will be important for specific use cases and will potentially become standard capacities as the market evolves. When choosing the right storage microSD card to implement into your video surveillance system, make sure the card is designed specifically for the application – does it include the right levels of endurance and performance to capture continuous streams – can it withstand environmental challenges and wide temperature extremes – will it enable preventative and preemptive maintenance to provide years of service? It is critical for the surveillance system to be able to collect video footage whether the camera is connected to an NVR or is a standalone camera as collecting footage at the base of the surveillance system is the most crucial point of failure. As such, failsafe mechanisms are required to keep the camera recording until the network is restored.
