Despite their advantages, cloud-based ANPR solutions are not without limitations or challenges in their implementation. These are mostly technical but can, at times, be the result of budgeting concerns as well. There are several factors that a customer should be aware of before installing an ANPR solution.
The most obvious limitation is that analytics on the cloud may not be suitable for solutions that require immediate actions taken based on the insights. For instance, a solution that opens a gate or boom barrier to a parking lot after identifying the user through ANPR needs to open gates within seconds. Failure to do this will cause in irate users or customers. You cannot afford to have network-related delays here, and hence, solution on the edge works better.
Cloud-based solutions – as the name suggests – require an Internet connection to work, so they may not be feasible for projects where having an Internet connection is out of the question.
“Event detection is also an issue in case of cloud-based ANPR, which can be avoided if the bandwidth allows for a continuous video stream of the monitored areas (as in this case our solution uses video analytics-based triggering), but this is not yet realistic in terms of accessible infrastructure and also when considering economic reasons,” explained Adrian Cseko, Head of Sales at Asura Technologies. “Another way to tackle the problem is either an image pre-selection mechanism set in place, triggers (like inductive loops) or cameras that include some sort of triggering mechanism, the latter solution, however, may prove more costly due to the price difference compared to standard IP cameras that provide sufficient image quality for ANPR.”
The basic rule of the thumb when selecting a camera for ANPR is that if a license plate is recognizable to a human eye, an ANPR solution will recognize it too. Having said that, since cameras on highways often have to deal with rugged conditions, there are several instances where they failed to give continuous clear visuals.
“Camera image quality is essential during all weather and lighting conditions,” said Walter Verbruggen, Sales Director at Avutec. “A dedicated ANPR camera system will always outperform another type of camera, as it is optimized for ANPR image quality, offers more speed and does not require any image or video compression, compromising the image quality.”
Camera placement is also essential to capture license plates. Too far or too near would result in images that are not useful. Similarly, installing cameras too high or too low would also be problematic. Finally, when the visuals are blurred because of rain, fog, dust, or other such elements, the ANPR solution would have difficulty recognizing the plates. It should be noted that these kinds of problems pose a challenge to any ANPR solution regardless of whether they are located on the cloud or the edge. Read about how to install an ANPR camera here.
Lack of customizability
Gabor Jozsa, CMO at Adaptive Recognition issues like network connectivity, is not limited to ANPR but could define any cloud-based system. However, a more significant limitation is the difficulty of providing services that may need certain unique recognition features.
“Limitation in customized features is an issue,” Jozsa said. “Sometimes, the customer’s application requires specific OCR engines and recognition functions which can be provided perfectly with our on-premise solutions”
Limitations vs. advantages
To conclude, both cloud-based and edge-based ANPR solutions have their advantages and disadvantages. Both are suited for different verticals and applications, which makes comparison difficult as well. Any decision to purchase from customers should be based on the application.

Building automation market has achieved significant growth in recent years, driven by a combination of decreased costs and increased awareness of the benefits. Smart building automation systems, which refer to the automated centralized control of a building’s heating, ventilation and air conditioning, lighting and other systems through building management or automation system, increases convenience, optimizes resource usage and has the potential to lower operational costs.
According to the research firm Stratistics MRC, the global building automation market accounted for US$ 57.83 billion in 2017 and is expected to reach $154.36 billion by 2026 growing at a CAGR of 11.5 percent during the period. Given this strong growth potential and the prospects of high returns, several companies are competing for market share. We compile a list of some of the top building automation companies to watch out for in 2020.
With a presence in several industries and over a century of market experience, the German company Bosch is one of the major players in the building automation sector. Under its building solutions division, Bosch offers integrated solutions for buildings, offering consultancy, installation and services for design and operation. Further, its Building Integration System (BIS) software solution helps in the management of different Bosch security subsystems including video surveillance, fire alarm, access control, and public address of intrusion systems into an integrated platform.
Another German company, with several years of experience under its belt, is Siemens. In a whitepaper, the company had said that the commitment and vision that Siemens has to the evolution of smart buildings is demonstrated by the investment the business has made in the digitalization agenda.
“This includes the acquisition of three innovative start-up companies specifically to strengthen its portfolio of solutions for smart buildings,” the company said. “These strategic investments – the purchase of Comfy by Building Robotics (provider of a building occupant app), Enlighted (provider of sensor and building analytics) and J2 Innovations (building automation and operating system vendor) – demonstrate a commitment towards staying at the leading edge of technology.”
The US-based Honeywell International is present in industries ranging from aerospace to physical security and consumer appliances. In the building automation space, the company has its Niagara Framework-based building management solution (BMS) that takes all aspects of your building and occupant needs into consideration to maximize energy efficiency and make the management of your facility simpler and more user-friendly.
The company’s software solution Vector Space Sense also helps customers understand how a particular building is being used, real-time, allowing management to take full advantage of the resources available.
The Irish multinational conglomerate offers a building automation system branded as Metasys, that connects your HVAC, lighting, security, and protection systems – enabling them to communicate on a single platform to deliver the information you need, helping customers to make smarter, savvier decisions while enhancing the occupants’ comfort, safety and productivity. Other solutions that Johnson Controls offers include BCPro, for Asian and Middle East Markets, and Verasys, a plug-and-play system for light commercial buildings.

When the India-based pharmaceutical giant Cipla considered ways to improve their manufacturing process, a major problem that caught their attention was that the machine vision cameras they used to quality-check finished products couldn’t quite identify transparent capsules. They also found that the solution they used then had difficulty in identifying dusty tablets. Such things could prove to be critical in ensuring operational efficiency, quality control and deciding production costs.
This is where Spookfish Innovations that develops machine vision solutions for manufacturing units in the pharmaceutical sector came into the scene. Cipla was clear on what they wanted. Solve these specific pill-identification problems of theirs. Spookfish, with its computer vision and machine learning algorithms, was able to do exactly that, saving a significant headache for their customers.
This is one of the many examples of how machine vision is transforming the manufacturing industry. The market is huge, as Anupriya Balikai, MD of Spookfish that has offices in Bristol and Bangalore explains.
“There is tremendous potential to bridge the in the manufacturing sector for machine vision,” Balikai said. “Just to give you an example, say you have a new product that is developed. Your machines would need a change in settings to inspect this new product and in the past, you would need an intelligent operator to change these settings. With machine vision and machine learning, you no longer need an operator, automatic learning algorithms would suggest what to change and how to change. ”
How it works
Technically, cameras by themselves just capture images, explained Rick Brookshire, Director of Product Development at Epson America. The so-called “smart cameras” have processors in them for vision processing. Vision systems and AI become significant when deciding what can be done with the captured visuals.
“For example, when training parts for recognition, AI can be used to look at hundreds of parts to define a more accepting model of a good part,” Brookshire said. “At Epson, we use Epson Vision Guide in combination with our IntelliFlex parts feeding system to auto-tune the feeder as well as determine optimal part quantities in the feeder system to maximize throughput. Other examples are where deep learning algorithms are used to help find defects.”
Elaborating on this point further, Shweta Kabadi, Senior Director and Business Unit Manager of Vision SW and Accessories at Cognex, listed the major role machine vision plays in the industrial vertical.
“AI-enabled cameras are used to perform four primary roles in factory automation: guiding, identifying, gauging and inspecting products,” Kabadi said. “Examples of guiding applications could include aligning a screen on a smartphone or guiding a robot to put a windshield in a car. Examples of identifying applications could include reading bar codes behind shrink wrap on a pallet, identifying laser-etched codes on metal pots or detecting components against noisy backgrounds with confusing patterns and glare.”
Actions such as measuring the width and depth of a brake pad as it moves on a conveyor belt are instances of machine vision being used in gauging applications. Identifying cosmetic defects, missing pieces and irregularities on finished products or components are examples of the technology being used in inspection purposes. This could include inspecting for potentially hazardous deformations on lithium-ion batteries as well.
Benefits of machine vision in factories
AI-enabled cameras allow manufacturers to perform critical functions without making contact with the product or slowing down their lines. They can inspect hundreds, or even thousands, of parts per minute, far exceeding the inspection capabilities of humans. They can also inspect object details that are too small to be seen by the human eye.

With rapid urbanization and increased population density in cities, there is a heightened need for mobility solutions. Private vehicles are a preferred mode of transportation for many people in developed economies. As the standard of living continues to go up in several parts of the world, more and more people and companies buy new cars.
This has brought with it the challenge of creating space to park these cars in cities. The concept of the parking lot has evolved quite a bit over the years from just a place where people could leave their cars to places that are managed by automated solutions to ensure security and operational efficiency.
Malls and other commercial centers are also increasing in cities, attracting more and more people who prefer to drive in with their cars. This has increased the need for efficient parking lot management system in malls, not just to make sure people have a hassle-free experience but also to avoid wasting money and resources.
Nevertheless, there are several challenges that mall management and solution providers face when it comes to managing parking lots. Some of these challenges are the reason automated systems have come into place. Others persist despite their introduction.
Manual ticketing is time-consuming
Before venturing into the realm of automated parking lot systems, let’s take a look at why electronic solutions should be used. Manual ticketing systems take up time and require more manpower, resulting in higher costs and slower processing.
While this may be seen as an obvious issue to many, the fact is that there are still several malls and commercial entities across the globe that are yet to make a shift from manual ticketing systems.
Paper-based ticketing systems also make the job of information management difficult. In case of any untoward incidents, the management should be able to provide information about any vehicle parked in their space immediately. Automated electronic systems make this possible.
Access control ticketing system failure
One of the worst nightmares for a parking lot manager is the malfunctioning of any access control system. Since malls are often open for long hours and mostly every day of the week, parking lots will be in use most of the time. If there is any failure to the entry management system, there could be delays customer upset.
False damage claims
According to Arvind Mayar, CEO of Secure Parking Solutions, there are always some customers who try to claim that their car was damaged while in the parking lot when in reality the car was already damaged before entering the lot.
To deal with such an issue, there is a need for high-quality surveillance solutions that can provide clear images of the condition of a vehicle at the point of entry. Adequate lighting is also required to support the surveillance systems that are being installed.
Installing new parking solutions at existing malls and shopping centers is a challenge. But perhaps what’s even more difficult is the integration of these solutions into third-party systems. For instance, surveillance and fire may be managed by a different vendor. Unless all the companies involved are willing to support integration, operations could be tough.
Open standards for traffic data exchange like Datex II become relevant in this context. Fortunately, major companies do support such standards. For instance, Siemens’ intelligent parking solution offers links to third-party applications via open standards such as DATEX II. This interface can allow integration of the data produced by the system for payment providers, enforcement and in-vehicle platforms that consume data in order to provide services that add value to the infrastructure in place.

The hardware needs of businesses to deploy a face recognition solution can vary depending on the application. Not every situation requires the highest resolution camera or the highest computing power, nor does every every environment pose the same challenges (e.g., lighting, crowding, weather, etc.).
Generally, in order to deploy a face recognition system what is needed are a well-tuned camera, local compute power, and software. Hardware systems must be paired with the appropriate compute power to run facial detection efficiently, which depends on whether you are managing a high- or low-density environment.
However, hardware requirements can vary greatly depending on the application and deployment architecture. For example, secure-access use cases, where you are viewing a few faces at a given time, can leverage lower-resolution cameras with lower frame rates and require less compute power (in addition to deploying fewer cameras), which effectively lowers your total cost of ownership (TCO), explained Dan Grimm, VP of Computer Vision and GM of SAFR and RealNetworks.
On the other hand, when using watchlists, deploying more cameras can improve accuracy and
performance. Grimm added, “If the facial recognition platform supports a distributed architecture by doing detection at the edge and recognition in the cloud, then you’ve not only lowered TCO, you’ve also increased your ability to scale in a massive way.”
In the early days of face recognition, there was often a tradeoff between accuracy and device power. “Lower powered devices, either in terms of chipset, bandwidth requirements or camera resolution, suffered from lower accuracy,” noted Doug Aley, CEO of Ever AI.
Today Ever AI has had success in being able to deploy on everything from a single core legacy processor all the way up through a cluster of high-powered GPUs, like an NVIDIA T4. “There are now other companies like ours where the accuracy tradeoff is no longer an issue,” Aley added.
Nowadays, speed is where the major variability comes in — the more powerful the hardware, the faster the speed of matching and the faster the overall user experience.
Aley explained that most modern chipsets, especially from a quad-core onward, are going to be very fast. Furthermore, today’s face recognition models, and the frameworks off which these models are built, are getting more adept at handling lower-power chipsets.
Shawn Mather, Director of Sales for the U.S. at Intelligent Security Systems (ISS) highlighted software integration issues over complications with hardware. Software providers, however, can overcome these challenges by making their solutions compatible with VMS solutions and electronic access control solutions.
The type of face recognition — 2D or 3D face recognition technology — a businesses chooses to deploy may also come with its own specific set of challenges and requirements. A report by MarketsandMarkets noted that captured images from earlier 2D face recognition technology was highly dependent on illumination, meaning poor lighting significantly affected image quality. Another challenge was the “incompatibility of integration between software tools and biometric hardware devices.”
However, the report expects 3D technology to have the largest market share in the coming years. Unlike 2D technology, 3D technology is not dependent on illumination. This enables it to capture higher-quality images in uncontrolled environments, such as poorly lit or completely dark areas.
Something else to consider in the years to come are face recognition cameras, where the recognition process is done on-board at the frontend. These types of cameras, though, require strong computational power since all of the tools for recognition are on-board. While several camera companies are developing face recognition cameras, the overall market is still in a fledgling state, but may be something to look forward to in the future.

The first step a machine vision system will take to understand images collected by cameras is to adjust these images through processes such as sharpening, cutting or zooming. This processing provides meaningful information for computers to read.
As humans, we have a set of eyes capturing images, which then are sent to the brain for image identification. For machines, cameras and other visual sensors perform the function of the eyes, with software, artificial intelligence, FPGA (Field Programmable Gate Arrays) chips, CPUs and GPUs filling in for the brain.
“Image processing can be seen as the first step in analyzing video data, before it is fed to the system’s computer vision algorithms,” said Jerome Gigot, senior director of marketing at Ambarella.
Processing software can sharpen an image to improve readability, change the exposure for a clearer shot, or to zoom in and crop certain information, such as a barcode or address located on a package.
“The type of data that will be analyzed heavily depends on the manufacturing function that needs to be performed,” said Gigot.
Industrial objects, for instance, can be inspected by size, shape, color, and texture. These same variables can be also used to recognize agricultural or biological objects.
The second step is to have an algorithm that first distinguishes between the many different pieces of an image, then identifies the edges and models its subcomponents.
In manufacturing, computer vision isn’t limited to a single niche purpose. Some decode barcodes, while others inspect for defects. The latter is powered by neural networks that can compare how a piece of equipment looks versus how it is supposed to look. When the algorithm finds an anomaly, it flags the issue for the user. Other possibilities include monitoring, predictive maintenance, safety inspection and inventory management.
Gigot offers the example of food processing. At a food processing plant, a neural network detects and instructs the system to remove bad apples in real time as they speed through the scanner and before they shipped out to stores.
Seeing beyond vision with predictive capacity
Lian Jye Su, Principal Analyst, ABI Research
“In addition to cameras, machine learning-based machine vision can also
incorporate data collected from various sensors, including LiDAR, radar, ultrasound, and magnetic field sensors. The rich set of data will provide further insight into other aspects of production processes,” said Lian Jye Su, Principal Analyst at ABI Research.
Conventional machine vision only detects product defects and quality issues predefined by humans. With the help of machine learning algorithms, machine vision can pick up unexpected product abnormalities or defects, providing flexibility and valuable insights for manufacturers.
Machine vision-powered predictive maintenance utilizes machine learning and other connected devices to monitor data and components in order to taking corrective actions before machinery breaks down. It creates a zero-downtime situation for manufacturers, creating cost savings.
Another use of machine learning-equipped machine vision systems is for monitoring worker safety. Devices can track people and predict the movement of equipment, helping to prevent dangerous interactions between people and machines.

Multisensor cameras boast various advantages, among them coverage of wide areas with fewer devices and reduced installation and maintenance cost. But as with all other IT or electronic devices, there are various things to consider when selecting a multisensor camera. At the same time, there are certain installation tips that the user/installer may find helpful.
Basically, choosing a multisensor camera requires an understanding of the user’s own needs and requirement. The following are some of the factors that the user should look at when choosing the device that best suits them.
Fixed vs. multidirectional
Multisensor cameras come with either fixed or adjustable lenses. For the former, cameras allow 180-, 270- and 360-degree field of view. “Users should pick a camera with the FOV that best matches their use case. For example an open square or parking lot can benefit the most from a 360 degree, and a long street will only require 180 degrees,” said Saleh Makarb, Product Marketing Manager at Dahua Technology.
A multisensor camera with adjustable lenses, meanwhile, allow the user to see several directions at once. “An adjustable multi-directional camera provides more flexibility in situations where you don’t require a continuous view, but would rather use the camera to look at specific areas. In this case, each camera can be adjusted independently. One camera can face the doorway, while the other cameras are used to view specific areas of a large room,” said Bob Mesnik, President of Kintronics.
If the area to be surveilled has a lot of movements, then choosing a camera with good compression would be a good way to save bandwidth and storage space. “When combining smart coding and H.265 compression, we are able to deliver a lower bit rate from the four 4K cameras than a standard 4K camera at H.264. The four repositionable lenses can reduce blind spots and monitor a variety of intersection shapes in city centers,” said Karen Sangha, Field Marketing Manager at Panasonic.
“The compression technology is important for users,” said Shengfu Cheng, Director of Marketing and Product Development Division at VIVOTEK. “Our MS9390-HV can save on storage and bandwidth by up to 90 percent by adopting H.265 and VIVOTEK self-developed Smart Stream III technology compared to H.264.”
For outdoor applications, the camera should be resistant to harsh weather and vandalism. “An IP66 rating (or higher) is ideal for cameras installed outdoors that can be subject to extreme weather conditions,” said Jeff Whitney, VP of Marketing at Arecont Vision.
Sangha of Panasonic, meanwhile, mentions their ClearSight Coating technology. “It’s unique to Panasonic and aims to repel water drops to enable the camera to capture clear images even when it is raining. The ClearSight coating is also effective at repelling dirt, which reduces the frequency of cleaning the dome cover. This makes them particularly suitable for capturing evidential grade images even under challenging of conditions, such as use in city surveillance,” she said.
Also in outside applications, it would be ideal if the multisensor camera has good WDR and lowlight performance to address various lighting conditions. “Multi-sensor cameras are still security cameras that need to extract information from scenes with challenging lighting conditions. So, you should look for adequate resolution for the detail you need, good enough low light and wide dynamic range performance and for cameras that can adapt to these changing conditions dynamically,” said Kevin Saldanha, Principal Product Manager for Imaging at Pelco by Schneider Electric.
“If the area to be captured has simultaneously shaded and bright light conditions, wide dynamic range at 120dB usually provides the best visual balance. If the end user demands clear color images in an area with poorly-lit conditions, it would be prudent to find a model with LED illumination built into each gimbal of the multi-sensor camera,” Whitney said.
Generally speaking, with one cable and one IP address, a multisensor camera is easy to install – a draw that attracts users in the first place. But there are still installation tips that installers and users can find helpful.
“Panoramic multi-sensor cameras are best mounted higher than 3 meters and at least 3 meters away from moving objects in the scene to capture wide field of view. Multi-directional cameras need to be mounted in locations from which you can cover the targeted areas of interest,” Saldanha said.
“The correct tilt and positioning of both multi-sensor and multi-adjustable cameras are critical to get the maximum coverage of an area – for example, not placing the camera right next to a wall since the lateral views will be completely covered,” Cheng said.
Again, a full understanding of what the customer’s needs are is an important prerequisite. “We usually start with the requirements and expectations of the customer before we suggest installation locations. It is important to understand what the customer expects to see. Sometimes there are unreasonable expectations. For example, these cameras are not the best for identifying a license plate that is 10 meters away,” Mesnik said.

With the number of senior citizens increasing and a lot of them opting to live at home rather than in a nursing facility, how to care for them in a home setting has become a top priority for governments and care providers. In this regard, technology can help, and many countries in the world have already adopted related products and solutions.
Needless to say, aging has become a phenomenon across the globe. According to figures by the United Nations, the number of older persons — those aged 60 years or over — is expected to more than double by 2050 and to more than triple by 2100, rising from 962 million globally in 2017 to 2.1 billion in 2050 and 3.1 billion in 2100. The study also suggests globally, population aged 60 or over is growing faster than all younger age groups.
Amid this trend, providing care for seniors so that they can live with independence and dignity has become a top agenda for both public and private sector players. More and more, nursing homes and assisted living facilities have sprung up to accommodate the elderly, providing care for them.
Despite this, there are still senior citizens who opt to stay at homes due to the comfort and convenience factors. And thanks to technology, seniors can be better taken care of in their homes via telehealth or remote monitoring solutions with which healthcare professionals can monitor individuals’ vital signs and provide immediate assistance should something happen.
Meanwhile, various smart home technologies can help make home living easier for seniors. Voice assistants can provide information and even serve as agents that keep senior citizens company so they don’t feel lonely or isolated.
What some countries are doing
In fact, these technologies are already seen in several countries around the globe. The following are some examples.
According to a post by the European Commission, a EU-funded Smart Service Power project has developed an internet of things (IoT) platform – mainly accessible via natural language assistance software – for use with internet-connected sensor technologies to help the elderly live independently at home for as long as possible. The platform is now being trialed in the German cities of Dortmund, Duisburg and Arnsberg.
“The platform can remotely monitor a person’s condition in real time, predict any deterioration in their health, detect a medical emergency, and alert healthcare emergency services if help is needed,” the post said. “The technology assures users that medical help will be provided when they need it.”
According to an article by the US News and World Report, Nordic countries, including Sweden, are quite advanced in this regard. Among the technologies deployed in Swedish homes cited by the article are: smart health care systems that can track seniors’ food intake, sleep patterns, heart rates and other daily habits; and smart medicine dispensers that can track medicine intake, compare data with a symptom log and improve compliance.
Japan, being an aging society, is home to some of the most advanced technologies that help with seniors living at home. According to a post by Web Japan, “monitoring support robots” using communication and IoT technologies are set up in several locations in the senior citizen’s house and measure motion, temperature, humidity and light levels via built-in sensors. Also according to the post, sensors attached to household appliances collect data that give a pattern of daily activity for the senior citizen; family members receive an alert via email if there are any abnormalities such as a vacuum cleaner that is switched on for several hours.
