Face recognition: Privacy concerns and social benefits
Face recognition: Privacy concerns and social benefits

News reports and opinion columns about face recognition are appearing everyday. To some of us, the term sounds overly intrusive. It even makes people shrink back into their seats or shake their head in disgust, picturing a present-day dystopia. Yet to others, face recognition presents technology-enabled realistic opportunities to fight, and win, the battle against crime. What are the facts about face recognition? Which side is right? Well, there is no definitive answer because, as with all powerful tools, it all depends on who uses it. Face recognition can, in fact, be used in an immoral or controversial manner. But, it can also be immensely beneficial in providing a safe and secure atmosphere for those in its presence.  Concerns of facial recognition With the increased facial recognition applications, people’s concerns over the technology continuously appear throughout news channels and social media. Some of the concerns include: Privacy: Alex Perry of Mashable sums up his and most other peoples’ privacy concerns with face recognition technology when he wrote, “The first and most obvious reason why people are unhappy about facial recognition is that it's unpleasant by nature. Increasing government surveillance has been a hot-button issue for many, many years, and tech like Amazon's Rekognition software is only making the dystopian future feel even more real”. Accuracy: People are worried about the possibilities of inaccurate face detection, which could result in wrongful identification or criminalisation. Awareness: Face recognition software allows the user to upload a picture of anyone, regardless of whether that person knows of it. An article posted on The Conversation states, “There is a lack of detailed and specific information as to how facial recognition is actually used. This means that we are not given the opportunity to consent to the recording, analysing and storing of our images in databases. By denying us the opportunity to consent, we are denied choice and control over the use of our own images” Debunking concerns  The concerns with privacy, accuracy, and awareness are all legitimate and valid concerns. However, let us look at the facts and examine the reasons why face recognition, like any other technology, can be responsibly used: Privacy concerns: Unlike the fictional dystopian future where every action, even in one’s own home, is monitored by a centralised authority, the reality is that face recognition technology only helps the security guard monitoring public locations where security cameras are installed. There is fundamentally no difference between a human security guard at the door and an AI-based software in terms of recognising people on watchlist and not recognising those who are not. The only difference is that the AI-based face recognition software can do so at a higher speed and without fatigue. Face recognition software only recognises faces that the user has put in the system, which is not every person on the planet, nor could it ever be. Accuracy concerns: It is true that first-generation face recognition systems have a large margin for error according to studies in 2014. However, as of 2020, the best face recognition systems are now around 99.8% accurate. New AI models are continuously being trained with larger, more relevant, more diverse and less biased datasets. The error margin found in face recognition software today is comparable to that of a person, and it will continue to decrease as we better understand the limitations, train increasingly better AI and deploy AI in more suitable settings. Awareness concerns: While not entirely comforting, the fact is that we are often being watched one way or another on a security camera. Informa showed that in 2014, 245 million cameras were active worldwide, this number jumped to 656 million in 2018 and is projected to nearly double in 2021. Security camera systems, like security guards, are local business and government’s precaution measures to minimise incidents such as shoplifting, car thefts, vandalism and violence. In other words, visitors to locations with security systems have tacitly agreed to the monitoring in exchange for using the service provided by those locations in safety, and visitors are indeed aware of the existence of security cameras. Face recognition software is only another layer of security, and anyone who is not a security threat is unlikely to be registered in the system without explicit consent. The benefits In August 2019, the NYPD used face recognition software to catch a rapist within 24 hours after the incident occurred. In April 2019, the Sichuan Provincial Public Security Department in China, found a 13-year-old girl using face recognition technology. The girl had gone missing in 2009, persuading many people that she would never be found again. Face recognition presents technology-enabled realistic opportunities to fight, and win, the battle against crimeIn the UK, the face recognition system helps Welsh police forces with the detection and prevention of crime. "For police it can help facilitate the identification process and it can reduce it to minutes and seconds," says Alexeis Garcia-Perez, a researcher on cybersecurity management at Coventry University. "They can identify someone in a short amount of time and in doing that they can minimise false arrests and other issues that the public will not see in a very positive way". In fact, nearly 60% Americans polled in 2019 accept the use of face recognition by law enforcement to enhance public safety. Forbes magazine states that “When people know they are being watched, they are less likely to commit crimes so the possibility of facial recognition technology being used could deter crime”. Saving time  One thing that all AI functions have been proven to achieve better results than manual security is speed. NBC News writes, “Nearly instantaneously, the program gives a list of potential matches loaded with information that can help him confirm the identity of the people he’s stopped - and whether they have any outstanding warrants. Previously, he’d have to let the person go or bring them in to be fingerprinted”. Facial recognition can also be immensely beneficial in providing a safe and secure atmosphere for those in its presence With AI, instead of spending hours or days to sift through terabytes of video data, the security staff can locate a suspect within seconds. This time-saving benefit is essential to the overall security of any institution, for in most security threat situations, time is of the utmost importance. Another way in which the technology saves time is its ability to enable employees (but not visitors) to open doors to their office in real time with no badge, alleviating the bottleneck of forgotten badge, keycode or password. Saving money A truly high-performance AI software helps save money in many ways. First, if the face recognition software works with your pre-existing camera system, there is no need to replace cameras, hence saving cost on infrastructure. Second, AI alleviates much of the required manual security monitoring 24/7, as the technology will detect people of interest and automatically and timely alert the authorities. Third, by enhancing access authentication, employees save time and can maximise productivity in more important processes. The takeaway AI-enabled face recognition technology has a lot of benefits if used correctly. Can it be abused? Yes, like all tools that mankind has made from antiquity. Should it be deployed? The evidence indicates that the many benefits of this complex feature outweigh the small chance for abuse of power. It is not only a step in the right direction for the security industry but also for the overall impact on daily lives. It helps to make the world a safer place. 

How intelligent video surveillance supports smart mobility
How intelligent video surveillance supports smart mobility

The ease of getting from point A to point B, the effective movement of goods and services, and the flexibility and integration of various modes of transportation are key aspects of mobility today. Smart Mobility has been a key theme in the transportation industry for a while. The idea is to keep traffic flowing and help people to get where they need to be, in a smarter way. To this end, industry players are now innovating and introducing advanced technologies and solutions. Examples include intelligent traffic management systems, free-flow tolls, autonomous driving, smart location solutions, and more.   At the same time, traffic congestion, aging infrastructure, rapid urbanisation, and increasing sustainability demands are also intensifying the need for smart mobility solutions. One way to overcome these obstacles is to use intelligent video surveillance technology for improved traffic management, making the roads safer and more efficient for every user, while also reducing emissions. Perceptive intersections Relying on intelligent video analytics, traffic video cameras identify traffic build ups at intersections by counting numbers of vehicles crossing an intersection and detecting their speed, while also counting the number of vehicles queueing in real-time. Aggregated data informs the system when to switch traffic lights to red or green. Intelligent optimisation for traffic signals ensures more effective traffic flow. Aggregated data informs the system when to switch traffic lights to red or green The benefits? Improved safety on the roadways; intersection reconstruction can be avoided; drivers can be advised about the speed of their route, forecasted by traffic signals; reduced wait times and stress for commuters; reduction of harmful emissions; and positive impact on public satisfaction. Road safety Traffic incidents can be disastrous, not merely for causing congestion on the roads but sometimes far worse – resulting in injuries and even fatalities. These incidents have many causes, not the least of which is drivers willfully violating traffic laws. Video technology can aid in detecting all kinds of events – for example, illegal parking, running a red light, wrong-way driving, speeding, and making illegal U-turns can all be detected by smart camera technology.   By using deep learning technology, cameras can recognise these events and traffic authorities can be immediately notified and take necessary actions even before traffic incidents occur. Scenarios include stopping a driver who is occupying an emergency lane, or notifying a driver who parked their car illegally. Furthermore, ticketing systems can be incorporated to further regulate driving behaviours. Benefits here include incident prevention, better driver performance, and increased safety on the roads and streets, to name just a few. Scenarios include stopping a driver who is occupying an emergency lane, or notifying a driver who parked their car illegally Public information Sharing information is key to keeping city drivers and travelers informed. Intelligent communication about warnings and updates helps everyone save time, avoid frustration, and simplify everyday mobility. This can be done via traffic guidance screens displayed at highly visible locations, such as congested areas, transportation hubs, shopping malls, and city plazas – or even at your fingertips on your favorite mobile apps! This can be done via traffic guidance screens displayed at highly visible locations Traffic video cameras generate real-time data of traffic flow and incidents, sending it to a central platform to further fuse with data from third-party systems such as radar and GPS systems. They also disseminate traffic information, including traffic status, warning and advisory notices, as well as parking status.  The benefits are improved public awareness of traffic information, improved travel convenience, overall enhancement of mobility in the city, and more.   The Hikvision practice Hikvision has accumulated sophisticated experience in traffic management both at home and abroad. Product lines offer versatile solutions to resolve multitudes of problems in urban traffic management, traffic incident management, highway management, and more. Going deeper, it’s essential to note that efficient signal control management is dependent on the quality of traffic data, system algorithms, and the hardware devices in use; it is also closely related to the mobile environment, such as road conditions, historical traffic conditions, and urban infrastructure. Because of this, no single solution solves traffic congestion everywhere. Hikvision believes that only by working closely with city authorities, public safety organisations, consultants, even academia and other relevant stakeholders, can applications and operational processes be developed to achieve the best possible outcomes. The possibilities for traffic video data are endless, especially now that it can employ artificial intelligence for advanced functionality. Harnessing its power will make all the difference, but the ultimate goal remains the same: safe and smooth traffic, smart mobility, and improved quality of human life.

Dahua thermal monitoring solutions help businesses become COVID-19 pandemic-ready and resume operations
Dahua thermal monitoring solutions help businesses become COVID-19 pandemic-ready and resume operations

Dahua Technology, the globally renowned video security and smart IoT solutions provider, is helping businesses reopen amid the COVID-19 pandemic. Thermal imaging, face detection, and other technologies play key roles in screening for skin temperature and determining whether someone is wearing a mask or not. Thermal temperature monitoring “Since the start of the COVID-19 pandemic, Dahua has been devoted to providing an array of solutions to help keep businesses running wherever possible,” remarked Jennifer Hackenburg, Senior Product Marketing Manager of Dahua Technology USA. Jennifer adds, “Our offerings reflect the varied needs of different business environments – we strive to provide options for every budget and application.” SafetyTemp Thermal Temperature Station Compact and simple, the SafetyTemp Thermal Temperature Station is ideally suited for small installations Thermal temperature monitoring lets business owners get fast, accurate readings of the skin temperature of employees and customers. People pass through a checkpoint where a monitoring station measures the temperature of their skin, while no physical contact is made and the traffic flow remains smooth. Compact and simple, the SafetyTemp Thermal Temperature Station is ideally suited for small installations. It takes measurements from up to six feet away and in only 0.2 seconds, raising audible alerts if a person’s skin temperature is above a user-defined threshold. It can also help determine whether a person is wearing a mask. Dahua Thermal Temperature Monitoring Solution For medium and large installations, the Dahua Thermal Temperature Monitoring Solution is a more robust option that incorporates a hybrid network thermal camera, an NVR, and a blackbody calibration device for highly accurate skin temperature measurements (±0.54° F). Like SafetyTemp, this is a contact-free solution that makes screening fast and efficient. As people pass through the checkpoint, their skin temperatures are captured and the system can send alerts about temperature or mask status via the 4K 16-inch 1U NVR (DHI-NVR5216-16P-I) or a mobile app (DMSS). Thermal cameras deployed Two different camera options are available, including a new model (DH-TPC-BF3221-T), which is well-suited for medium-sized businesses due to a lower price point. It offers accurate readings from up to 16 feet away. The high-end model (DH-TPC-BF5421) has a higher resolution thermal lens, lower NETD, and large aperture, resulting in more pixels and less noise in the image. This, in turn, means more data points for the system to analyse and lets the camera obtain readings from up to 23 feet away. Handheld Thermal Temperature Monitoring Device Handheld Thermal Temperature Monitoring Device, DH-TPC-HT2201 features a 3.5mm camera For a portable solution, the Handheld Thermal Temperature Monitoring Device, DH-TPC-HT2201 features a 3.5mm camera that can be aimed directly at the subject from a safe distance. AI temperature measurement facilitates high accuracy (±0.9° F), and an alarm sounds when a person’s skin temperature exceeds a user-defined threshold. This simple to use, cost effective device is best employed in small applications with a dense customer or personnel base. A built-in, rechargeable, lithium-ion battery lasts more than eight hours in between charging. Smart Motion Detection and Face Detection When mask detection is the top priority, a new 5MP dome camera (N55DY82) gives users an active alarm message when it detects people without masks within its field of view. A wealth of other features, including perimeter protection, people counting, heat mapping, Smart Motion Detection (SMD) and face detection, make this high-performing camera an excellent security solution as well. Highly accurate, it can be paired with a thermal temperature camera for a complete solution. Floor-Standing Digital Signage Dahua’s 55-inch Floor-Standing Digital Signage (DHI-LDV55-INDOOR) complements digital monitoring checkpoints. It offers a 1080p display screen that is customisable to display safety requirements, provide instructions for those preparing to have their temperature measured, or simply point people in the right direction. The digital signage can also be deployed as a component of Dahua’s new flow control solution It supports a wide range of audio and video encoding formats and has built-in media player software and a USB player for displaying advertisements. The digital signage can also be deployed as a component of Dahua’s new flow control solution. This solution helps businesses maintain social distancing protocols and avoid overcrowding while streamlining efforts and reducing manpower for facilities where occupancy is regulated. People-counting camera installed A people-counting camera installed at a restaurant entrance, for example, keeps track of how many people have entered and exited. Working in tandem, the display tells customers when they may enter the restaurant, grocery store, or retail store, or when it is at capacity and they need to wait. The entire solution can integrate with the mask detection camera and thermal temperature solutions for large applications needing to manage a complex set of safety and health requirements. “Convenience and accuracy are important to our customers as they reopen their businesses,” stated Hackenburg, adding “Dahua has risen to the challenge by providing flexible options for a variety of needs and budgets, supporting a more seamless transition into this new way of doing business.”
