  For video security cameras and systems, capturing images simulates our sense of sight, extending the power of people’s ‘eyes.’ But what if they could use other kinds of senses like ‘hearing’, ‘smelling’, ‘heat sensing,’ or even detections that are beyond visual range – to identify and respond to security incidents? From single to multiple sensors, video security systems evolve with each new trend to fulfill a new potential, and there are already many beneficial advancements being developed across the industry today – and expanding perceptions is one. There’s no doubt multiple-perception capabilities will make video security systems more powerful – sensing the outside environment, identifying events, and providing more detailed information. This will also create more possibilities for video security systems to be used in ever wider scenarios and applications. Cameras integrated with radar Cameras integrated with centimeter and millimeter wave radars are becoming a popular approach in object detection. Radar has shown great advantages in object detection and movement tracking, which can offer accurate and reliable detection over long distances, unaffected by any kind of weather. Equipped with a deep integration of radar and video, a multi-dimensional camera extends perception in perimeter protection to find objects earlier, track movement, and provide visual images to verify detected objects. Such integration overcomes the technological bottleneck of traditional one-dimensional video perception. It has been applied in traffic safety management to improve detection of potential obstacles or traffic incidents at great distance, out of visual range and in low-visibility conditions. The integration is also ideal for monitoring large, exposed spaces with harsh weather such as sea ports, airports and large open industrial areas. Video cameras equipped with sonar arrays Automobile horn noise bothers residents who live near major roadways, but in many cities it has been difficult for traffic control departments to reduce it. A video camera equipped with sonar arrays capable of collecting both sound and image data can be used for automobile horn detection. The camera integrated with sonar sensors can precisely detect and locate the source of a vehicle’s horn while identifying the vehicle and generating photos and videos of the event as evidence. Local law enforcement can respond as necessary, helping to reduce noise pollution on roadways and in communities with rules against the unnecessary use of horns. Multispectral imagery Multispectral imagery is another promising approach for cameras to perceive information from non-visible light spectra. Popular thermographic cameras use infrared radiation to perceive temperature of objects, and the detection of other non-visible light spectra is currently being explored in the security industry. For instance, electric arc is a key phenomenon to indicate that power grids are aging, and the electrical discharge emits non-visible ultraviolet (UV) lights. Here innovative UV detection can boost the perception capabilities of cameras to capture invisible electric arc phenomena, and finds a critical application in safety-checks at aging power grids in the electricity industry. Alarm systems with wide range of detectors Along with video security devices, other conventional security systems have incorporated multiple perception sensors, too. For example, alarm systems that employ a wide range of detectors and peripherals have borrowed the practice. Today’s wireless alarm systems normally include a compact panel hub and a wide range of detectors and peripherals, covering intrusion detection, video verification, smoke and flood detection etc. With these detectors and peripherals, alarm systems can collect data and multi-dimensional information to fully protect homes, commercial buildings, factories, and more. And there is more to come Increasingly powerful edge computing and intelligent algorithms are becoming available to the security industry, and we are constantly seeing more integrated security devices and systems with multiple sensors. Therefore, we believe that in the near future, additional ‘senses’ – like smoke detection, humidity and temperature measurement, and even gas pressure detection – can be widely embedded in video cameras and systems to precisely monitor and report events or incidents. The multi-dimensional perception trend will very likely and very powerfully shape security systems in the near future and endow them with more capabilities to create safety for users.  

Pranali Chaudhari Sr. Data Scientist at Dimensionless Technologies Pandemic brought the travel industry to a standstill last year but with vaccinations being administered around the globe, things are starting to look up and the normalcy would return sooner than later. Public transport systems, monuments and places of mass gathering are always under serious threat from radical organisations. There have been multiple security incidents due to the failure of personnel at security checkpoints – 9/11, London Bombing or Mumbai blasts are prime examples of this. Millions of people pass through security checkpoints daily across airports, metro stations, railway stations, prisons, government buildings, stadiums etc. With the pandemic receding and travel picking up the queues have started to get longer at these checkpoints now The current baggage screening process uses X-ray scanning technology which has not had any upgrades in the past many years. Any security lapse has always been attributed to human screeners, policies and processes focused on better training methods for improving their performance. One such example could be reducing the duration for which a screener looks for threats in the x-ray scan to 20 minutes. But the incidents continue to happen, at least 3 firearms are missed by TSA (transportation security agency). Manual detection of banned items in x-ray images is an intricate task and is highly prone to human error due to fatigue. Baggage handling and security are major operational challenges, and sometimes contribute to flight delays as well. To mitigate these challenges, a high-performance intelligent baggage scanner system is needed. Dimensionless Technologies, an AI company founded by IIT alumnus has developed BaggageAI, using artificial intelligence and data processing technology, to completely overhaul this manual process and automatically detect and locate threat items in x-ray scan images. It is a sophisticated high-performance artificial intelligence (AI) based system for automatic object detection of banned items in baggage through x-ray images. It looks at each image like a human eye, outlines banned objects and sends alerts to the screen. Existing scanners work on manual detection, but this solution automates the process of finding and locating prohibited items in the x-ray image of the scanned baggage. BaggageAI has been developed for the most frequent common items, which are contraband like guns, knives, sharp objects, power bank, battery, coconut, lighter, e-cigarette etc. Solution readily deployable for The solution has been selected by the Airport Authority of India for pilot and deployment to improve efficiency of security personnel. The pilot run of the solution was successfully conducted at Pune International airport last year and is being put into other airports like Ahmedabad International airport and Delhi International airport. Metro Corporations like DMRC and Mumbai metro are also trying out the solution and the pilot run is scheduled at a couple of metro stations in March. BaggageAI is a very fast solution that can process up to 3 images per second or up to 180 bags/ minute. This will greatly reduce the time taken at security checkpoints and make it highly convenient to the passengers. It helps detect threats with high accuracy and efficiency, and reduces false alarms, saving invaluable time. High throughput helps airports handle more passengers and flights per day, resulting in higher revenues and profits. This boosts passenger security significantly by removing human errors in the baggage screening process. It can be effectively deployed at places with high passenger traffic such as airports, metros, malls and railway stations where there is a security risk. Another amazing benefit of the solution lies in the fact that it can get integrated to any existing x-ray baggage scanner system. This greatly enhances the possibility of upgrading all existing machines and improving the security checkpoints to the next level. “Human screeners are expected to be correct 100% of the time – which is an impossible task. That’s why we have brought machines into play to ensure the stress on screeners reduces significantly and the process is automated. It will go a long way in enhancing security and customer experience across the globe. With central monitoring of the baggages through a combination of human and AI can significantly reduce operational cost across various application areas,” explained Kushagra and Himanshu, the founders of the organisation.  

Abhishek Chhabra Market Development Manager, Thomas Bell-Wright International Consultants, Dubai When people in India started writing the building codes around 6th century AD (Vastu Shastras) the options on methodologies of construction and materials were very limited and the behavior of people was fairly predictable. Not anymore! Nowadays the complexity and variables affecting construction have been changing very quickly, and unfortunately, the laws and rules (building codes) which define minimum requirements take several years to change. This lag is a systemic challenge and is world-wide. But certain key guides that have been published by International Organization for Standardization (ISO) continue to help define quality and safety across all industries while the laws catch-up – whether it is electrical safety, industrial products, food, pharma or inspections inside factories, construction sites or hospitals. These guides provide the much-needed unbiased language to help procure and deliver products and services in a fast-changing world. Let us understand how to use these to ensure fire safety too. Any procurement needs an unbiased system that brings about the basic assurance needed for any transaction – ‘getting what you want.’ With so many fire accidents happening in India (and the world), everyone wants these fires not to threaten life, and avoid property damage. This note suggests simple ways to implement actionable steps that can be added to technical specifications and commercial clauses across contracts to ensure fire safety, thus safeguarding investments and ensuring minimum damage to life and property in case of a fire incident. Who are the stakeholders? For the construction industry, the image #01 defines some key stakeholders who need to enter into commercial contracts (to get what they want) with each other. The key language used to define expectations is often a specification document. Now defining fire safety and its implementation often slips out due to lack of awareness to ask ‘exactly’ what is needed.       These stakeholders get involved directly or indirectly in design, build and maintain. Image #02 defines some key steps that ensure the learnings from past mistakes (captured in building codes and other guidance documents) are avoided. The tricky part is implementing these concepts with the limitations of time, money, availability of correct products or materials, and lack of training, awareness and comprehension of implementation. A better understanding and usage of the referred ISO guides makes it easy to design, build and maintain. A common thread across these steps is procurement of materials and repeatability of installation. Getting commercial and technical language to align across the contracts of stakeholders makes it easy to assure the delivery of what is designed.     Simplifying procurement: Materials & installation for fire safety Before we read on, we should know the real difference between voluntary and mandatory. Making anything mandatory requires a law to be enacted – this requires a consensus. Such laws require technical documents (like building codes) to be referred to as well. And these technical documents also require a consensus. Here lies the risk due to the lag which is well known. A lot of construction gets finished while/ before these two consensuses are arrived at. Hence large hotels chains, hospitals, commercial and retail establishments and insurers and reinsurers never rely on just the minimum mandatory requirements in any given geography. They understand that the rate at which building materials and construction methodologies are evolving; reliance on the minimum mandatory is a high risk, and it will lead to a loss of reputation, money and of course life and property. So, it is common practice to use more evolved and adopted building codes and even more. Hence the technical specifications need to be current and updated, and these are implemented using advanced conformity assessment mechanisms for increased assurance. Conformity assessment is all the activities completed to determine if a product or service meets specific requirements. Let us read how conformity assessment mechanisms are jointly defined by the experts from 165 countries (including India). These experts form and define the International Organization for Standardization (ISO), and define these conformity assessment mechanisms. May of these standards have been helping government bodies as well as large investors and specification writers on ways to assess and define ‘getting what you want.’ See image #03 which gives an overview of the terms and definitions used by ISO’s Committee on Conformity Assessment (CASCO). Below are the three standards whose references should be utilized effectively for procurement. These three are also used to describe a case study in this article.     ISO/ IEC 17025: General requirements for the competence of testing and calibration laboratories. ISO/ IEC 17065: Conformity assessment requirements for bodies certifying products, processes and services. ISO/ IEC 17020: Conformity assessment requirements for the operation of various types of bodies performing inspection. Understanding simple steps with a case study A 300 room 5-star luxury hotel in Dubai would cost around AED 300-400 Million (INR 600-800 Crore) to be built. The MEP works which is about 35% of this cost (INR 250 Crore) has a key element to create compartmentalization for ensuring fire safety. Compartmentalisation or to create a compartment of the area where fire gets initiated helps ensure that a fire that is contained for 2 or 3 hours at a given location giving enough time for evacuation and rescue. This is created using fire doors, partition walls, as well as thorough penetrations and other mechanisms which help seal the openings for pipes and utilities. If the specifications or implementation for this fire safety plan is weak or done incorrectly, the property may have a big fire and would be closed for about a year at the least. So, when re-negotiating with suppliers and contractors to save money here, it should well be kept in mind that what an impact such a savings could lead to – the impact of a small fire versus a huge fire! Without factoring cost of land, the earnings of such a property (after removing operators’ expenses, the earnings before interest, taxes, and amortization) are estimated to be…
