Human beings have a long-standing relationship with privacy and security. For centuries, we’ve locked our doors, held close our most precious possessions, and been wary of the threats posed by thieves. As time has gone on, our relationship with security has become more complicated as we’ve now got much more to be protective of. As technological advancements in security have got smarter and stronger, so have those looking to compromise it. Cybersecurity Cybersecurity, however, is still incredibly new to humans when we look at the long relationship that we have with security in general. As much as we understand the basics, such as keeping our passwords secure and storing data in safe places, our understanding of cybersecurity as a whole is complicated and so is our understanding of the threats that it protects against. However, the relationship between physical security and cybersecurity is often interlinked. Business leaders may find themselves weighing up the different risks to the physical security of their business. As a result, they implement CCTV into the office space, and alarms are placed on doors to help repel intruders. Importance of cybersecurity But what happens when the data that is collected from such security devices is also at risk of being stolen, and you don’t have to break through the front door of an office to get it? The answer is that your physical security can lose its power to keep your business safe if your cybersecurity is weak. As a result, cybersecurity is incredibly important to empower your physical security. We’ve seen the risks posed by cybersecurity hacks in recent news. Video security company Verkada recently suffered a security breach as malicious attackers obtained access to the contents of many of its live camera feeds, and a recent report by the UK government says two in five UK firms experienced cyberattacks in 2020. Cloud computing – The solution Cloud stores information in data centres located anywhere in the world, and is maintained by a third party Cloud computing offers a solution. The cloud stores your information in data centres located anywhere in the world and is maintained by a third party, such as Claranet. As the data sits on hosted servers, it’s easily accessible while not being at risk of being stolen through your physical device. Here’s why cloud computing can help to ensure that your physical security and the data it holds aren’t compromised. Cloud anxiety It’s completely normal to speculate whether your data is safe when it’s stored within a cloud infrastructure. As we are effectively outsourcing our security by storing our important files on servers we have no control over - and, in some cases, limited understanding of - it’s natural to worry about how vulnerable this is to cyber-attacks. The reality is, the data that you save on the cloud is likely to be a lot safer than that which you store on your device. Cyber hackers can try and trick you into clicking on links that deploy malware or pose as a help desk trying to fix your machine. As a result, they can access your device and if this is where you’re storing important security data, then it is vulnerable. Cloud service providers Cloud service providers offer security that is a lot stronger than the software in the personal computer Cloud service providers offer security that is a lot stronger than the software that is likely in place on your personal computer. Hyperscalers such as Microsoft and Amazon Web Service (AWS) are able to hire countless more security experts than any individual company - save the corporate behemoth - could afford. These major platform owners have culpability for thousands of customers on their cloud and are constantly working to enhance the security of their platforms. The security provided by cloud service providers such as Claranet is an extension of these capabilities. Cloud resistance Cloud servers are located in remote locations that workers don’t have access to. They are also encrypted, which is the process of converting information or data into code to prevent unauthorized access. Additionally, cloud infrastructure providers like ourselves look to regularly update your security to protect against viruses and malware, leaving you free to get on with your work without any niggling worries about your data being at risk from hackers. Data centres Cloud providers provide sophisticated security measures and solutions in the form of firewalls and AI Additionally, cloud providers are also able to provide sophisticated security measures and solutions in the form of firewalls and artificial intelligence, as well as data redundancy, where the same piece of data is held within several separate data centres. This is effectively super-strong backup and recovery, meaning that if a server goes down, you can access your files from a backup server. Empowering physical security with cybersecurity By storing the data gathered by your physical security in the cloud, you're not just significantly reducing the risk of cyber-attacks, but also protecting it from physical threats such as damage in the event of a fire or flood. Rather than viewing your physical and cybersecurity as two different entities, treat them as part of one system: if one is compromised, the other is also at risk. They should work in tandem to keep your whole organization secure.

The sound of sirens in the distance is commonplace, nowadays. Whether related to a medical emergency or everyday crimes, such as theft, property crimes, and so on, we’re all accustomed to hearing these sirens by now. It is worth noting that many incidents that police respond to take place at night. According to a recent report by the Sleep Judge, more than half of murders, manslaughter, sexual assaults, robberies, aggravated assaults and motor vehicle thefts happen long after the sun has set. To anyone looking to address the round-the-clock security challenge, deploying the most comprehensive surveillance solution is a must, and this means, looking at the instrumental role illumination plays in video capture. Limitations of Traditional Video Surveillance If surveillance cameras can’t be used to prevent, detect and/or resolve crimes that occur in these areas, the entire security operation is obsolete For surveillance cameras relying on video analytics and artificial intelligence (AI) to deliver functionalities such as facial recognition, license plate reading and motion detection, nighttime crimes can pose something of a problem. Without adequate illumination, images from video cameras are grainy and unusable. Without proper lighting, potential criminals and moving objects essentially become indistinguishable, at night, thereby inhibiting even the most advanced security technologies. This limitation of traditional surveillance technology not only hinders immediate police response, but it also stops crime investigations dead in their tracks. Often, without video evidence that is clear and discernible, conviction in a court of law is next to impossible. A common response to this issue is to place security cameras near streetlights or well-lit areas. After all, according to NPR, street lights are effective in deterring crime,  as “there are people — neighbors, pedestrians or police — to actually see suspicious activity.” However, even if streetside and primary entrances are well lit, the areas that still need most to be surveilled are rear or side doorways shrouded by darkness, unlit back alleys, and so on. If surveillance cameras can’t be used to prevent, detect and resolve crimes that occur in these areas, the entire security operation is obsolete. Best-in-class security solutions must be able to see everything, day and night. A Purpose-Designed Solution to the Problem Addressing this issue is easier than you might think. Much like a human eye needs some sort of light to “see,” so does video surveillance technology. Integrating external illuminators into a security solution can optimize camera performance exponentially, expanding a camera’s video capture and coverage abilities and ensuring the operation of video analytics, day and night. Opting for an external illuminator allows system integrators to select a device that matches the exact emission range of a camera’s field of view (FOV). The result is an evenly lit visual field, where captured images are clear and effective for security purposes. The two most common options available to integrators include infrared (IR) and white light illuminators. Each technology is built to optimize particular deployments, depending on their needs. Infrared Versus White Light IR illuminators emit IR light, which is invisible to the human eye and perfect for covert surveillance operations. When cameras need to be able to detect potential threats over long distances, IR illuminators are perfect for the job as they typically have longer emission ranges. IR illuminators are optimal for surveillance operations in license plate recognition, border patrol, safe cities, theme park, and medical sleep lab applications. If an end user needs to implement full-color video analytics for identification purposes, such as facial, object and license plate recognition, white light illuminators are undoubtedly an integrator’s best bet. IR illumination and traditional thermal security cameras, after all, are only able to provide black-and-white images, whereas object recognition software often identifies objects based on their color. White light illuminators installed alongside AI-powered surveillance cameras enable enhanced video image clarity, which, optimizes video analytics performance. When customers want to physically deter suspicious activity, deploying white light illuminators is effective. A recent study out of Crime Labs New York found that businesses that deployed visible lights to deter crime “experienced crime rates that were significantly lower,” which “led to a 36 percent reduction in ‘index crimes’”. On top of all this, LED based white lights operate at low running costs and typically have long lifespans, saving end users thousands of dollars a year in energy costs without having to sacrifice surveillance optimization. External Versus Built-In Illumination Security customers looking to use lighting to deter crime and improve the performance of video surveillance may consider “all-in-one" solutions, as some cameras have LEDs (light emitting diodes) built into them. These LEDs typically encircle the lens and therefore shed light in whatever direction the camera is pointed. However convenient these may seem, built-in illumination can cause problems.Cameras deployed without proper illumination are rendered blind, especially at night First, LEDs built into cameras and next to other electronic components often cause heat to build up, which attracts insects that can trigger motion detection and obstruct a camera’s view. This heat buildup also shortens the LED lights lifespan. Built-in LEDs also tend to create “hot spots” with glare and reflection back into the camera, often because these lights only cover a 30-degree field of view (FOV), even though the average camera’s FOV is 90 degrees. This issue can severely limit a camera’s visibility, essentially rendering those remaining 60 degrees dark and unusable. All in all, when integrating lighting solutions into your security deployment, a cost-effective solution that enhances a camera’s video capture and coverage abilities, are external illuminators because they offer flexible choices of field of view and distances. Best-in-Class Solution When it comes to criminal conviction in a court of law, “seeing really is believing.” Cameras deployed without proper illumination are rendered blind, especially at night, just as any security officer would be when patrolling the same unlit area. To guarantee end users the most reliable and highest performing security solution, consider integrating best-in-class illumination into your offerings.

In today’s market, efficient use of bandwidth and storage is an essential part of maintaining an effective video surveillance system. A video management system’s ability to provide analysis, real time event notifications and crucial image detail is only as a good as the speed and bandwidth of a surveillance network. In the physical security industry, H.264 is the video compression format used by most companies. Some companies also employ H.264 enhancements to compress areas of an image that are irrelevant to the user at a higher ratio within a video stream in order to preserve image quality for more important details like faces, license plates or buildings. The H.265, H.264’s successor, will be increasingly used for compression in the future. Some companies are already using H.265 in their cameras and video management systems, while a host of other manufacturers are certainly preparing for its broader adoption in the years to come. Video Compression Technologies Reduced bandwidth and storage requirements are the primary benefits of video compression technologies Reduced bandwidth and storage requirements are the primary benefits of video compression technologies. In some cases, H.265 can double the data compression ratio of H.264, while retaining the same quality. Increased compression rate translates into decreased storage requirements on hard drives, less bandwidth usage and fewer switches – all of which reduce overall costs of system ownership. H.265 compression delivers a lower bitrate than H.264, which is relevant to end users and integrators because the lower bitrate reduces strain on hardware and can reduce playback issues. It’s very important that the compression format that is used is supported in all of the different components of a system: cameras, desktop computers on which the VMS is running and the VMS itself. It is also good for end users and integrators to understand the basics of video compression. Having a basic understanding of compression allows users to tweak settings to reduce bandwidth usage even more. Many cameras come with default settings that can be changed to ultimately reduce costs. ONVIF Physical Security In the physical security industry, ONVIF is working to incorporate into its specifications the use of new formats such as H.265 but is not directly involved in developing the compression standards themselves. With Profile T, the new ONVIF video profile released will employ a new media service that is compression agnostic. This means that it can support new video compression formats, including H.265, as well as new audio compression formats, with the ability to include new video and audio codecs as needed in the future without having to redesign its media service. In the physical security industry, ONVIF is working to incorporate into its specifications the use of new formats such as H.265 Standardization organizations that are directly addressing new compression standards include the International Telecommunication Union (ITU), the Moving Picture Experts Group (MPEG) and a joint commission of the International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC), which is addressing the coding of audio, picture, multimedia and hypermedia information. Other compression formats on par with H.264 and H.265 are being developed by companies such as Google. H.265 Compression Formats Using products that employ H.265 compression will reduce costs through bandwidth reduction, as will changing default settings on cameras, which are often conservative. Having a basic understanding of compression formats and how to tweak camera factory default settings also gives integrators the ability to further reduce bandwidth for added costs savings and increased system performance. These enhancements will analyse which parts of an image are most important and adjust local levels of compressions accordingly It is also worth noting that H.265 enhancements will likely be developed by camera manufacturers to further reduce bandwidth, as was the case with H.264. These enhancements will analyze which parts of an image are most important and adjust local levels of compressions accordingly. While H.265 itself is ready for prime time, its value as a tool for IP-based surveillance systems is dependent on support for the codec in all parts of the system – the VMS, server hardware, graphics cards and camera. Though widespread H.265 adoption is predicted, providers of these components are jumping on the H.265 bandwagon at different rates of speed. ONVIF is including support for H.265 in its new video profile, Profile T, because it believes it will become the most widely used compression format and ONVIF recognizes the need to anticipate that migration as a future need of the industry. The new media service, which will be implemented with Profile T, will be future-proof in that when new compression formats are released in the future, ONVIF can adopt them very quickly. That flexibility will definitely help integrators.

Dahua Technology, a renowned, video-centric provider of smart IoT solutions, announced a major rebranding to reflect the company’s growth and evolution within the North American video surveillance market. WizSense (pronounced “Wise Sense”), Simplified Analytics for Accurate Results, and WizMind (pronounced “Wise Mind”), Advanced Analytics for Ultimate Performance, will be sub-categories under Dahua’s Analytics+ umbrella. Each line encompasses existing product lines as well as new product offerings. “With this launch, we are unifying our products under two new product categories, WizSense and WizMind, to align with new and existing customer’s needs in finding solutions faster,” remarked Jennifer Hackenburg, Senior Product Marketing Manager of Dahua Technology USA.

Compatible NVR and Penta-brid recorders come in 4TB, 8TB, and 10TB models. Thermal temperature monitoring solutions These solutions should not be solely used to diagnose or exclude a diagnosis of COVID-19 or any other disease “WizSense and WizMind technologies both take security further by providing advanced analytics that provide deeper insights, increased accuracy, and time saving alerts,” said Hackenburg. “By offering this new streamlined branding, it is easier than ever for dealers to find the line of technology that will include the level of analytics needed for their installation.” Dahua’s thermal solutions, including the SafetyTemp Thermal Temperature Station, the Thermal Temperature Monitoring Solution, and the Handheld Thermal Temperature Monitoring Device, are not FDA-cleared or approved. These solutions should not be solely or primarily used to diagnose or exclude a diagnosis of COVID-19 or any other disease. Telethermographic temperature measurement Elevated body temperature in the context of use should be confirmed with secondary evaluation methods (e.g., an NCIT or clinical grade contact thermometer). Public health officials, through their experience with the solutions in the particular environment of use, should determine the significance of any fever or elevated temperature based on the skin telethermographic temperature measurement. The solutions should be used to measure only one subject’s temperature at a time. Visible thermal patterns are only intended for locating the points from which to extract the thermal measurement.

The COVID-19 global pandemic continues, and more and more companies are looking for ways to continue (or resume) operations while minimizing the coronavirus’s negative impact on their workforce, or potentially contributing to disease spread among the wider population. Thermal cameras have been proposed as a solution to screen individuals for elevated body temperature since the beginning of the pandemic. However, the technology has its detractors, and there are regulatory questions. We asked this week’s Expert Panel Roundtable: How can thermal cameras be used effectively for fever detection to screen for infectious diseases?

Dahua Technology, a video-centric, provider of smart IoT solutions, offers a wealth of low-light technology for surveillance in dark or nighttime environments. The latest addition to their wide-ranging line of security cameras for the Dahua USA market is White-light LED Night Color technology. Dahua Technology USA boasts several different low-light camera models to meet a variety of needs in environments with very low ambient light. Each camera incorporates an ultra-Starlight image sensor, which has a set of optical features to balance light throughout the scene and improve the clarity of the image. Low-light cameras also utilize Smart Image Signal Processing (ISP). Extracting useful information “Smart ISP converts an image into digital form while performing operations that enhance the image and extract useful information. It lets the camera identify and correct imperfections caused by the lens, color filter, or sensor,” explained Jennifer Hackenburg, senior product marketing manager at Dahua Technology USA. Dahua’s flagship low-light standard, Starlight technology, employs large apertures (maximum f/1.6), in addition to the sensors and Smart ISP described above, to balance light throughout the scene. Together, these technologies let Starlight cameras produce richly colored, identification-level images without distortion in illumination of 0.004 to 0.009 lux. Starlight cameras have infrared (IR) cut filters that switch to black and white mode when the camera senses that insufficient light is available to reproduce good color images. When night mode is triggered, the filter disengages, allowing IR as well as visible illumination to reach the image sensor. Achromatic large aperture lens Night Color does not require a True Day Night IR cut filter; instead it uses a high-performance sensor and ISP The latest advancement in light sensitivity is Night Color technology. Night Color cameras use high-performance image sensors that generate exceptional color images long after an IR camera would have converted to a black and white image. Night Color does not require a True Day Night IR cut filter; instead it uses a high-performance sensor and ISP, as well as an achromatic large aperture lens, to produce crisp, clear images. This light-sensitive technology allows the camera to capture more available light, creating full-color images with high detail and contrast. Night Color requires at least 1 lux of ambient or artificial light. When a visual deterrent to crime is imperative, white-light LEDs (Light Emitting Diodes), are built into Dahua’s new 4MP ePoE Night Color Network Dome Camera (N45EJ62). Real-Time perimeter protection Smart illumination, where the camera automatically activates the LEDs at low lux levels, adjusts exposure time and LED intensity to avoid overexposing the image. The camera performs Dahua’s Analytics+ functions at the edge for complex, real-time perimeter protection surveillance, Smart Motion Detection, and face detection. Enhanced Power over Ethernet (ePoE) extends transmission distances up to eight times over CAT5/CAT6 cables and converts existing, coax‐based analog systems into IP systems. “Our broad portfolio of low-light cameras gives installers and end-users a variety of options to choose from, based on their individual needs,” commented Hackenburg. “Whether low lux capabilities are most important, or you need advanced technology that enables full color images in near-complete darkness, Dahua helps security operators see more.”
