In a move towards improving women’s safety in the city, Delhi government recently announced installation of 150,000 CCTVs in residential and commercial hubs across national capital region. This is an addition to the 140,000 surveillance cameras that the government is already in the process of installing in these areas. While cities like Delhi have long depended on video surveillance to enhance public safety, today’s smart cities are harnessing those solutions for a multitude of citizen-centric civic purposes, including traffic management, lighting, parking enforcement and more.
This is due in large part to the fact that cameras themselves have become intelligent computing devices that offer video analytics and the ability to integrate with disparate systems and devices. Among the many potential applications for which surveillance and other data can be combined for smart city applications is transportation. By deploying surveillance cameras with object detection and recognition analytics, officials can automatically detect stalled cars, wrong-way drives and other obstacles that can impact both safety and travel times. Using this insight, cities can use traffic management and/or digital signage systems to alert drivers to potential issues and reroute them to avoid these obstacles.
This is just one example of how municipalities can implement smart city platforms and technologies to achieve these goals. At the heart of these systems are the solutions used for storing all this data. Below are some key factors and best practices to consider when evaluating these solutions, which are the foundation for smart city applications.
Tying it all Together
According to IHS Markit, the amount of data generated worldwide by surveillance cameras alone is expected to reach 2,500 petabytes per day in 2019. A case in point is the imminent installation of surveillance cameras in the fleet of NCR’s buses. The city already has a widespread rapid transit system – Delhi Metro, which stretches 373 KM and is covered by over 9,000 CCTV cameras. With round the clock monitoring, these cameras are bound to generate a tremendous amount of data. However, the true value of this data lies in the ability to aggregate and analyze it in order to provide a fuller picture of overall transport operations and detect any dysfunction or malicious activity.
While enhanced by artificial intelligence (AI), today’s surveillance solutions are capable of providing the kind of actionable insights and intelligence smart cities require. At the heart of these applications are surveillance storage solutions, which are capable of aggregating all this data both at the edge for immediate analysis and real-time intelligence as well as in back-end environments for long-term analysis, overall trends and deep learning analytics that make the system smarter over time. These robust solutions are built to withstand the rigors of smart city applications and deliver a number of other features that in turn benefit municipalities.
Finding the Best Storage Fit
In the age of the IoT and AI, where devices are generating more data than ever before, deciding how to properly store all this data has become a critical consideration. Depending on a city’s needs, there are several approaches available, including storage at the edge (close to where the video or data is captured), in the cloud (a large, centralized backend storage server or servers) or even a combination of both, which some experts are calling IT 4.0. For smart cities with hundreds or thousands of cameras and IoT sensors, cities should take a multiple-layer approach to storage architecture that delivers the benefits of both edge- and cloud-based storage.
The main reason for this is that streaming large amounts of video and data to the cloud is expensive and can suffer from significant latency issues. The solution for smart cities is to deploy technologies that aggregate, filter and analyze data at endpoints and at the edge and then have relevant alerts sent to the video management system at the head-end for review and response. This allows data to be quickly processed and notifications to be delivered, which can improve public safety.
For example, when a municipal camera detects an incident using video analytics or AI, it can send an alert to a monitoring or command center, allowing a police officer to respond quickly. A CCTV camera system built with a surveillance-optimized hard drive allows dispatchers or operators in the command center to access video of the incident to further assess the situation, enabling them to provide the officer with real-time situational awareness and actionable intelligence about the incident.
To identify deeper trends, video and data can then be uploaded to the cloud, where providers utilize high-quality enterprise and solid-state drives. This large repository of data collected over a longer period of time can then be analysed for deeper insights – for instance, to identify peak traffic hours and traffic patterns throughout a city, allowing officials to make decisions that can improve people’s commutes, such as synchronizing traffic lights at certain intersections.
Data Security is key
Given the sensitivity of smart city data and the potential ramifications of a network breach, cybersecurity is a paramount concern. Naturally, this means that any camera, device or sensor connected to the network must offer top-of-the-line cybersecurity measures against vulnerabilities. Data can also be stolen from hard drives themselves due to improper disposal. To combat that possibility, it’s important to select drives that offer hardware-based encryption as well as secure methods for erasing data.
To avoid system lapses and drive failures, and the data loss this may lead to, municipalities should ensure there is redundancy in their systems. They must also augment this by subscribing to data rescue or recovery services, which allow data to be recovered for up to two years in some cases. These types of services are especially crucial for law enforcement or other public safety personnel who require data to be stored for lengthy periods of time.
In conclusion, while there is no doubt that smart city applications offer the ability to improve operations in a number of areas to enrich public lives, a robust storage infrastructure serves as the foundation for these initiatives. By following the above best practices, cities can choose storage solutions that offer high performance and reliability, and ensure they are deploying it in the most appropriate way, both of which are key to determining the success of any smart and safe city initiative.
Dynamic Caching- Emerging Trend, Need of Tomorrow
Authored by Amit Singh, Managing Director, Zenlayer India
Dynamic content caching is a term that’s synonymously trending with discussions around Content Delivery Network (CDN) industry. In fact, with the growing popularity around CDN Dynamic Content Caching is often the claim you will hear from most CDN players. Let me simplify for you how the modern technology makes caching of dynamic content possible.
Most content on the website is collection of both static and dynamic content pages. The word ‘static’ we know is something that remains constant. In computing, static content is any file that is stored in a server and is the same every time it is delivered to users like in the case of eBook, whitepaper, homepage of a website. On the other hand, dynamic content refers to any digital content that keeps changing based on factors specific to the user such as time of visit, location, and device. Text, audio and video formats are examples of dynamic content. This type of web content adjusts dynamically or in real-time allowing websites to individually adapt to different site visitors. Customised newsletters, emails are the most basic forms of dynamic content. Other examples include landing pages on website, forms and purchases, product pages with bounce offers like sales and coupons, targeted website advertisements, voice assistants, etc.
Dynamic content furnishes different information based on who the viewer is. Online store experience is a lot different for a frequent shopper than a first-time user. Online news website that displays latest news and articles on its web pages, also has dynamic content that keeps getting updated. Your blog feed, social media feed, personalized emails, are other examples of dynamic content that look entirely different for every user. Even interactive content that engages the users allowing them to interact with the content in order to change it are mostly dynamic in nature, like the comment area of your blog, social media sharing buttons, call-to-action buttons on a website and the popular ‘facetime’ or video chat via smart devices. But how is this constantly changing dynamic content being displayed on webpages, tv or smart devices in real-time? This is where CDN industry services and dynamic caching jointly play their roles.
CDNs and Dynamic Caching
‘Caching’ in computing, refers to the process of storing data or copies of files in a temporary storage area called cache. A cache’s primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. Caching enables quick access to the stored or cached content. Dynamic content is mostly event-driven for each user implying that the same cannot be served to multiple users and hence is difficult to cache. However, caching dynamic content is now viable with advanced CDNs the right technology mechanisms in place.
A Content Delivery Network (CDN) which today is a vital component of almost any modern web application, is a network of powerful computers located in geographically distinct places. It is designed to serve web content to visitors with great performance and efficiency. Ecommerce or media sites utilize the power of CDNs to frequently update content such as latest prices, news, weather forecasts, articles, featured products, breaking news, video etc on their web pages. Majority of content delivery networks frequently manage caching for sites through a global server network. CDNs can be configured to retrieve data from the origin servers and deliver dynamic content that is unique to the requestor. Intelligent caches and CDNs are able to quickly inspect requests and modify the behaviour of the caching logic as per requirements.
How dynamic caching works?
The HTML document is the backbone of the any webpage and is the first connection point between website origin server and the browser. With a large number of visitors, there is stress on the origin servers. But when the HTML document is cached, the caching server is the only one making a request to the origin server irrespective of the number of visitors. Thus, the website servers are freed up for critical transactions.
When a user visits a website using a CDN, and web traffic is geo-dispersed, it’s not always feasible and certainly not cost effective to replicate entire infrastructure across the globe. The traffic routes through the server that is closest to the user and serves up cached or stored versions of the site resources. This allows the site to load faster and eliminate requests back to the origin server. For caching, CDN reduces load on application origin and delivers a local copy of the content from a nearby cache server.
Role of cache servers
Proxy cache servers are the basic elements of a CDN’s network data centres, which are strategically situated around the world. Based on traffic patterns of individual regions, these points of presence (PoP) are chosen. Active locations with many users may have several data centres and remote locations with few users may have only one PoP to cover large geographic region. Cache servers act as a repository for website content, providing local users with quicker access to stored files. The cache server closest to the end user is chosen to reduce the connection time needed for transmission of website data.
Dynamic content is generated by running scripts in a CDN cache instead of a distant server thus reducing the response time to client requests and speeding up loading of dynamic web pages. It is served to client devices based on parameters like device type, time of day, user location, or data from third party APIs. Often, most content on a dynamic webpage is same for all users, and only few elements are dynamic. The dynamic content acceleration service leverages the high-quality connectivity between the network PoPs to improve response time. This service mainly takes advantage of the private back bone Software Defined Network (SDN) and achieves better ‘back-to-parent/origin’ network connectivity.
Advantages of Dynamic Caching
- Improved data retrieval and application performance
- Reduced hosting and server costs
- Reduced latency and improved IOPS for Q&A portals, gaming, media sharing, and social networking
- Dedicated caching layer enables systems and applications to run independently
- Data can span multiple cache servers and can be stored in a central location
- Controls like TTLs (Time to live) for successful cache and cache miss
- Decreased load on origin server
- Faster loading of sites
- Reduced bandwidth costs
- Improved access speed and user experience
- Reliable content delivery
- Highly resilient, secure and stable CDN cache servers
Uses of Dynamic Caching
- Website owners can gather visitor data like frequency of visits, pages visited etc and deliver personalized, dynamic web content at no additional cost
- Better interactive and personalised user experience
- Reduced load on the backend database and reduced time to load site
- Increased visitor time on site due to browser history insights and display of relevant content
- Increased conversion rates, bounce rates, and return visits
- High performance and no page layout break on multiple devices
- Easy maintenance
- Predictable Performance during peak traffic events like IPL or festivals
- Eliminate Database Hotspots
- Increase Read Throughput (IOPS)- In addition to lower latency, in-memory systems also offer much higher request rates (IOPS)
With 5G reaching India soon, and some parts of the world heading towards 7G, we can soon expect video replacing voice, text, and everything in between. Dynamic Caching could become the panacea to avoid overloading of data.
Voice Messaging – A Mastered Path to Rural India
Authored by Mr. Rajdipkumar Gupta, MD & Group CEO, Route Mobile Limited
Out of a population of 133.2 crores in India, a total of 101 crores of people are estimated to own active mobile connections as per TRAI in April 2018. With an exponential rise in the number of mobile phone users across the globe, the world is gradually progressing towards a technologically smarter era. Having said that, an estimated figure of over 74 crores is still using a basic feature phone. Considering India which majorly is segmented into two categories:
• Urban population and • Rural population
As per the report of census 2017, India constitutes a total of 66% of the population to rural area. While the smartphone penetration in these areas is just about 20.26%, there still is a deficit in reach of over 61.5 crores mobile phone users which are not smartphones out of 74 crores basic feature phone users. Taking under consideration that most of these people use basic phones which would not allow them to use the latest high-end features, reaching out to the mass population located in rural areas using a technology that requires minimum technology intervention becomes paramount.
While people even in the remotest locations are carving their path to synchronize well with digitization, it would be fair to join the hands of these technological advancements with our traditional systems in order to enhance the effectiveness of all the activities undertaken. More so, people are getting engaged and connected with a palm-sized technology which enables them to reach out to the world with nothing more than just a simple touch on their screens. Although 36% of the Indian population has been using smartphones, a huge chunk of 64% living in urban as well as rural India is still distant from getting a cutting edge technology mobile phones.
What if we bring together the power of voice broadcast with brand campaigns?
With an active base of 1.012 billion mobile phone users, employing voice campaigns will help reach the message of the brands across the country. Versatile by nature, voice broadcasting can be used to promote events, deliver poll surveys, deliver general announcements, and many such activities.
A panoramic view on traditional means of brand campaigns:
A typical campaign carried by a brand involves people, resources, and predominantly a need for people to be physically present. Along with that, some of the most commonly encountered obstacles are as follows:
- Need of human intervention
- Uncertainty in reachability
- High budget requirement
- Language Barrier
- Dependency on external factors
As various brands majorly look out for expansion and recognition, a physical campaign requires physical presence of people. Adding on to that, the success of these events is considerably dependent on the availability of space, equipment, and favourable climatic conditions. The entire event might go for a toss in case of unfavourable climatic conditions, or other factors.
Conducting campaigns with voice broadcasting will not just allow one to increase the reach but at the same time will proffer with a range of other features.
Adding a tinge of personal touch has always been beneficial. With Voice Broadcasting, one can customize their campaigns based on their needs, and the demand of their target audience. You can also alter the campaign to a degree that suits the expectation of your upcoming campaigns. Additionally, brands will have the freedom to speak in a dialect that works for the masses. Also, these speeches can be then translated in the choice of the language required in the future in order to make it understandable yet effective.
High-level of Flexibility
It lets you take charge of your own campaigns. Developed to be able to use with a high level of ease, you can modify the campaigns without affecting the other attributes of your campaign. A simple and easy to use format lets you decide the nature of your voice messages.
Elimination of one way communication
Moving a level further, with an Interactive Voice Response, you can also gather, and collate the responses from your audience. This sort of interactivity brings depth to your campaigns, making it way more effective.
In an era of mobile phones, there might be less than a handful of people who don’t own a mobile phone. Using voice broadcasting completely eliminates the need for a person to be physically present for that particular event. A simple, traditional call allows you to reach and address the mob with greater efficiency.
Elimination of hefty budget
Replacing a physical event into voice broadcasting cuts down on the cost exponentially. Rather than investing a lot of money on different factors that involves uncertainty in the performance of the event, investing in Voice Broadcasting proves to be favourable in terms of the cost incurred and also in terms of the productivity of an event.
Cut down on the time involved
While a conventional event demands a lot of time and human involvement which thereby calls for much more investment of time. Voice Broadcasting can be considered as a simple one-click process.
Voice Broadcasting, when it comes to its mechanism, is one of the simplest techniques to reach out to a large number of people. Owing to its simplicity, security, flexibility, and scalability, it has by far been a vital asset to many political campaigns. Suitable for an array of events ranging from promotional events, polling surveys, personalised messages to general announcements, and many more.
A simple six-step process is what it takes to incorporate Voice Broadcasting into your existing system.
Step 1: Record a voice message.
Step 2: Upload a file of mobile numbers that you wish should receive a call.
Step 3: Add the details of your campaign.
Step 4: Schedule your campaign.
Step 5: Make your campaign live.
Step 6: Access reports at the click of a button to understand the effectiveness of the campaign that can be sorted circle-wise or state-wise.
With a literacy rate of 71% in rural India, one of the most challenging problems is to be able to deliver messages that are understandable. As the major issue faced by the people living in remote/rural areas is the language barrier, implementing voice messaging will eliminate most of the shortcomings of the illiterates. Keeping this as a line of reference, creating a campaign that would keep the majority of the crowd to understand the message becomes crucial.
Voice broadcasting is extremely flexible that lets us run campaigns that would cater to the needs of the mob. Reaching out to a huge mob using a simple, lucid, and a dependable technology would bring success to most of the campaigns. Also, integrating a voice broadcast is as easy as any other physical campaigns.
