Hanwha Techwin Digital video recorders (DVRs)

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.

According to IHS Market, it is estimated that there are over 60 million security cameras in the United States, and other reports say these cameras capture more than four billion hours of footage per week. Over the last decade, IP camera technology has dominated the conversation as it has provided users with a broad offering of enhanced image quality and features. With a large percentage of existing security systems relying on analog, many end users looking for high definition (HD) video quality have been forced to take on a complete system overhaul. Infrastructure Overhaul For HD Video To make the switch, customers would need to change everything, from cameras to hardware to wiring– not to mention the lengthy installation process that would ensue. IP cameras also require higher Internet speeds and more cloud space. Whether constrained by budget, bandwidth or storage, many end users have been unable to adopt this new video surveillance method.Thanks to technological advancements within the security industry, HD over Coax offers a viable solution for integrators and end users alike Thanks to technological advancements within the security industry, HD over Coax offers a viable solution for integrators and end users alike. By utilising the current Coaxial cables, this offering yields high definition video, while requiring minimal infrastructure changes and is an optimal surveillance choice for security customers. Plus, with new advancements and updates being made frequently to this technology, there is a solution for every security need. The enhanced alternative of HD over Coax has been warmly welcomed in the security industry, thanks to its simple solutions and ever-evolving features. Many new analog HD cameras are “plug and play,” able to connect directly to existing Coaxial cables. This eliminates the need for a complete system change, creating cost-savings for the end user and an enhanced video quality offering. Easy Solutions For HD Video As a result, integrators can cost-effectively upgrade their customer’s surveillance solution while using their legacy infrastructure, making it an attractive option for end users and an easy sell for dealers. Latency in video is another common issue with network-based camera systems, where even the slightest delay in video surveillance can hinder security response HD over Coax cameras themselves are always expanding and evolving to meet a wide array of security needs. With the introduction of fisheye and multi-sensor cameras, users now have a multitude of coverage options, not to mention the introduction of 4K bringing resolution options to the same level as IP. Some newer technologies are even touting 4K cameras paired with 4K digital video recorders (DVRs) made specifically for analog systems. Longer cables grant transmission for up to 1600 feet, double the distance of standard analog solutions, and triple that of IP systems. This single cable is able to transmit both HD video and audio. Recently, broadcast quality audio over Coax has become available in limited models, a substantial improvement over older analog technology, which was unable to transmit audio. Stopping Video Delay Latency in video is another common issue with network-based camera systems. Even the slightest delay in video surveillance can hinder security response. IP cameras are forced to compress and packetize their video for transmission. The outcome of this is a reduced number of images per video, which in turn causes delay. HD over Coax on the other hand, delivers an unlimited amount of HD images in real time, with smooth motion and impressive clarity. Additionally, the point-to-point transmission delivers uncompressed video free of lag. Another touted benefit is that, unlike IP networked cameras, analog systems provide a more secure video transmission. With so much sensitive information housed on a businesses’ network, adding another point of network access through an IP camera can create concerns for cyber security risks. HD over Coax delivers an unlimited amount of HD images in real time, with smooth motion and impressive clarity Preventing Network Hacking With HD over Coax, the physical connections between the camera and DVR prevent network hacking. By keeping the video surveillance system offline, security professionals are able to direct their attention to the physical threats at hand, rather than having to focus on deterring cyber security risks. One of the primary difficulties of deploying HD video solutions is the fact that many older systems utilize a wide variety of HD standards and platforms. To make matters more complicated, after HD over Coax was brought to market, manufacturers raced to create their own version of this technology. Today, the most popular proprietary standards are HD-CVI, HD-TVI and AHD. However, integrators and customers found that attempting to manage multiple HD technologies proved to be near impossible.Integrators and customers found that attempting to manage multiple HD technologies proved to be near impossible Diversifying Surveillance Through One DVR To combat these issues, manufacturers have introduced products with more flexibility to their portfolios. One example of this is the penta-brid DVR which grants the ability to seamlessly integrate multiple technologies deployed across one application. This means that systems with diverse camera brands and technologies, such as a mix of HD-CVI, HD-TVI, AHD, analog or IP, can be connected through one DVR. For many end users with legacy analog systems, penta-brid DVRs give them greater freedom to choose between a variety of solutions, rather than being limited to one option. With video resolution increasing, the space needed to store the footage is similarly rising. Penta-brid technology has been able to adapt to these evolving needs, giving users ample storage space to house the HD and 4K surveillance video with some of the newest models including H.265 compression.  HD Casino Surveillance Made Simple For casinos, HD images are critical for identifying unauthorized personnel and unlawful behaviours to create a safe environment for guests and staff While HD over Coax is beneficial to many end users and integrators, those in the casino and hospitality markets find it crucial. With a combination of high profile guests, large amounts of cash on hand, constant crowds and strict industry regulations, reliable video surveillance is a must. Deploying new IP systems comes at a stiff price. When looking to upgrade their video surveillance, casinos must also be mindful of the installation process. When moving to an IP-based system, ripping out old wires and replacing them with new is the standard practice. This practice can be both disruptive and costly, not to mention gaming regulations require casino activities be monitored at all times so a complete system shutdown would result in revenue loss. This cost can be hard to justify, especially when the current legacy analog system remains in working condition with only the lower image resolution to date it. For these scenarios, the most cost-effective option is to leverage the legacy infrastructure, replace the existing cameras with new devices, and reap the benefits that HD video has to offer without any lapse in security. For casinos, HD images are critical for identifying unauthorized personnel and unlawful behaviours to create a safe environment for guests and staff. HD over Coax cameras now offer the same resolution as IP cameras with a plug and play approach, that cuts down on expense without sacrificing quality. For businesses and applications that are unable to adopt IP technology, whether it be cost or time prohibitive, HD over Coax now features most of the same benefits IP has to offer without breaking the bank. By providing clear images in real time, maximizing existing infrastructure, and affording cyber security benefits, HD over Coax provides an attractive solution for many end users and integrators.

Dollars spent by video surveillance customers must go towards ensuring high-availability capture, storage and on-demand access to live and archived video. Reaching this goal mandates high-availability of independent components – camera, network, storage (edge, external), internet connectivity, display, all Video Management Software (VMS) components and an architecture that can take advantage of this. In this note, we focus on seeing our way through to a video surveillance architecture, that provides high availability storage, access to live and stored video content. Of all options available to store recorded video, edge recording is the only one that is unaffected by network failure Edge Recording Of all options available to store recorded video, edge recording is the only one that is unaffected by network failure. This makes edge storage a must-have. But, this has some limitations at present: Edge storage capacity is limited. Edge media has a short lifetime, rated only for thousands of hours of continuous recording. Most cameras are not secure and physical damage to the camera could lead to catastrophic loss of edge stored content. As storage and compression technology evolve, the constraints imposed by (1) and (2) could go away. However, securing cameras will continue to be a barrier for most installations. Secure External Storage It is thus imperative to also store video in secure external storage. Such an architecture uses edge storage to fill in content gaps created by network, external storage outages. As edge storage technology improves, larger gaps can be filled in, but one will always need external storage. By our definition, ‘external storage’ is a solution stack that includes storage media and all software (including VMS) that provide access to this storage. Access To Live And Archived Video Access to live video can either be met by external storage or directly by the camera Every surveillance solution needs to provide access to live and archived video. Access to live video can either be met by external storage or (and) directly by the camera. All things being equal, having the camera directly provide live video access, is a higher-availability solution. There is dependence on fewer components in the chain. Solutions in the market use one of the above two approaches for access to live video. Due to limited capacity and low physical security of edge storage, it makes sense at present, to have external storage meet all requests for archive video. Thus, we are led to an architecture that has heavy dependence on external storage. Dual-Recording For high-availability, external storage must be architected with redundancy. Ideally, independent components that make up external storage – storage media, associated hardware and software (including VMS components), should be individually redundant and have smart interconnectivity. However, solutions in the market rigidly tie these components together. Failure of a single component causes failure of external storage. For e.g. hardware failure of a server causes VMS component failure AND storage failure. DR provides a smart way to provide high-availability for external storage For these solutions in the market, high-availability is achieved by having additional external storage units that step-in during outages of primary units. If these additional units continuously duplicate primary units, access gaps are minimized, and archive access is un-affected during primary unit outages. This is the idea behind Dual-Recording (DR).  To meet cost budgets, these additional units can be configured to store subsampled (framerate, resolution) video content. A small number of additional units can support concurrent outages of all primary units. A few-to-many redundancy. Rising Need For Dual-Recording Most cameras cannot be physically secured, and video content produced by a camera must be stored externally. Many VMS solutions use external storage to service live video access requests. Edge storage limitations impose restrictions on edge archive access at present. So, external storage is used to service requests for archive access too. Thus, a surveillance system ends up being over-dependent on external storage. DR provides a smart way to provide high-availability for external storage. As edge storage improves, it will be able to service archive access requests. VMS software will need to evolve, to use this capability smartly.

Utilities are an important element of critical infrastructure and, as such, must be protected to ensure that the daily lives of millions of people continue without disruption. Protecting utilities presents a unique range of challenges, whether one considers the electrical grid or telecommunications networks, the local water supply or oil and gas lines. Security technologies contribute to protecting these diverse components, but it’s not an easy job. We asked this week’s Expert Panel Roundtable: What are the security challenges of protecting utilities?

Recently, Planet Fitness, with the help of their preferred system integrator Adirondack Direct, incorporated a video surveillance solution from Hanwha Techwin and Genetec that not only enhances security, but also improves operations. When leadership evaluated security at their 70-plus corporate run locations a few years ago, they chose to incorporate a video surveillance solution that would address security needs and would be advanced enough to help with management and operations.  Each of Planet Fitness’ corporate-owned clubs throughout North America is outfitted with approximately eight to 15 video cameras that provide around the clock coverage of the parking lot, lobby, break room, the fitness area where members workout and other key areas – without invading private areas, such as locker rooms and other intimate spaces. After issuing a Request for Proposal, Planet Fitness Senior Vice President of Corporate Club Operations Jim Esposito said they tested several of the leading camera and video management software (VMS) solutions, but ultimately decided on Hanwha video surveillance cameras managed by the Genetec Security Center platform. Esposito said they wanted to use Hanwha’s 360-degree cameras in particular because they provide more coverage, yet they save in hardware expenses because fewer cameras are needed. 360-degree fisheye camera Hanwha’s SNF-8010 5 MP 360-degree fisheye camera provides 5MP at 20FPS which captures smoother video at a higher framerate with true day and night function. Built-in on-camera de-warping allows instant access to PTZ, quad view, and panorama views. Alarm triggers for the Hanwha SNF-8010 include intelligent motion detection, audio detection, tampering detection, alarm input and network disconnection.Adirondack Direct also offers a 24-hour monitoring service and liaisons with law enforcement when needed A typical system setup at Planet Fitness includes placing cameras 25 feet from the wall and 50 feet apart which provides almost 2,000 square feet of coverage per camera. Club managers, regional managers and corporate employees manage the system via the Genetec Security Center which provides convenient bookmarks of recorded incidents so that – instead of time spent searching through video – events are already tagged. Adirondack Direct also offers a 24-hour monitoring service and liaisons with law enforcement when needed. “We knew that Planet Fitness would need thousands of video surveillance cameras for this project and it’s very important to consider reliability and functionality as well as durability,” said Adirondack Direct Director of Security and Technology, Tim Collins. “Hanwha has the lowest customer return number and that means that they manufacture products that aren’t sidelined by constant replacement and repairs.” Collins said Adirondack Direct has long recommended Genetec’s Security Center for video surveillance management because it provides the best open-architecture platform, robust features and is easy to use. Security Center blends IP security systems within a single intuitive interface to simplify operations and empowers organizations through enhanced situational awareness, unified command and control and connectivity to the cloud. When a Lunk Alarm is pressed, Genetec’s Security Center creates a bookmark of the event which provides video evidence of what preceded the alarm and how it was managed Business intelligence  While the Hanwha-Genetec solution has provided an excellent security system – as well as protection against liability for slip and fall incidents – it’s also improved operations in multiple ways by providing invaluable business intelligence, said Esposito. Planet Fitness has a judgement-free environment for individuals who want to work out, but don’t want to have to endure the negatives so often found in gyms: loud grunts, the clanging of dropped weights and aggressive behavior. Anyone engaging in obnoxious behavior will likely be the recipient of a Lunk Alarm and the flashing lights, sirens and unwanted attention that accompanies it.Use of the Lunk Alarm – or lack of use – can be an indicator of how the club is operating Use of the Lunk Alarm – or lack of use – can be an indicator of how the club is operating. In order to monitor and evaluate use of the Lunk Alarms, Adirondack Direct has integrated the Lunk Alarm into the Hanwha-Gentec video solution. When a Lunk Alarm is pressed, Genetec’s Security Center creates a bookmark of the event which provides video evidence of what preceded the alarm and how it was managed. Potential medical emergencies Gyms typically have automated external defibrillators (AEDs) in the event a member suffers a medical emergency. At Planet Fitness facilities outfitted with the Hanwha-Genetec solution, once an AED is removed from its cabinet, a sensor is activated to shut off the music in the club to provide a calmer atmosphere. The system also creates a bookmark in the VMS and notifies managers and regional managers that an AED has been deployed. The Hanwha-Genetec Planet Fitness solution also provides key employee analysis that can help managers identify areas of improvement. Each facility has rubber floors that must be cleaned daily and Adirondack Direct has placed a sensor on a floor scrubber that creates a bookmark and recording in Security Center when the device is moved. Video evidence verifies whether the floor was actually cleaned or if the scrubber was just relocated. Break room sensors Each break room is outfitted with a sensor that creates a video bookmark every time the door is opened. If an employee visits too often, Planet Fitness management can reorient that employee on the proper policies and procedures. For day to day efficiencies, video analytics can be a valuable tool. If an employee is constantly leaving the front desk to go to a storage closet for a particular item, they can make changes including moving the item closer to the front desk. “If during an overnight shift the camera indicates that there was no motion at the front desk for a prolonged period of time, then that’s a problem,” said Esposito. “We expect someone to be in that position greeting and welcoming members so if someone isn’t there, the video can help us understand why.”If an employee visits the break room too often, Planet Fitness management can reorient that employee on the proper policies and procedures A big question for Planet Fitness – that can be answered via video analytics – is have they been losing sales opportunities without realizing it? “What we’re exploring now is a virtual line that counts the number of people that come and go in the club,” said Esposito. “We know how many people check in. So, if a club checks in 500 people in a day, but there are 600 people that enter the door, that can be lost revenue.” Esposito said they chose Hanwha cameras and the Genetec platform because they knew that they needed a solution that was at the forefront of technology, with the flexibility to grow with them and meet their future needs. He added the solution delivers a safe environment that is appreciate by everyone. “It’s somewhat of a security blanket for our members and employees,” he said. “They appreciate our no intimidation mantra and the fact that we have created this safe and secure environment that offers a judgement free zone where people can do their own thing.”

Global security company Hanwha Techwin recently took part in Intersec 2020, the security exhibition in the Middle East. Held in Dubai (UAE), the trade show provided the perfect opportunity for Hanwha Techwin to showcase its products, including Middle East-optimized devices and cutting-edge AI solutions, on a truly global stage. Intersec is an annual trade fair for the security and safety sectors, where all the latest trends and technologies can be found under one roof. At this year’s event, over 1,100 global security companies from 50 countries gathered to share their cutting-edge security solutions with the world. Hanwha Techwin to highlighted its “Expansion of Secure Life” theme by showcasing some significant technological breakthroughs, including the latest Wisenet AI lineup and up-to-date security solutions tailored to local demands of a diverse range of market sectors. At the company’s booth, attendees were given the opportunity to gain first-hand experience with Hanwha Techwin’s products, solutions and technologies that span across multiple sectors. Wisenet AI NVR Wisenet’s AI cameras are designed to accurately capture the unique attributes of objects With “AI technology” establishing an indispensable role in the video surveillance industry, Hanwha Techwin demonstrated its latest state-of-the-art AI solutions. Equipped with a powerful artificial intelligence (AI) engine that detects and classifies people and vehicles in real time, Wisenet’s AI cameras are designed to accurately capture the unique attributes of objects such as faces and license plates, while reducing false alarms caused by waving trees, video noise, and even shadows. The Wisenet AI NVR lineup is the first Wisenet NVR to feature AI. This provides real-time monitoring and video backup up to 8K resolution and further enhances user convenience through the new intuitive GUI. Hanwha Techwin also touched on its optimized solutions across numerous different vertical sectors including retail, transportation, plant and banking. The company’s retail and transportation smart security offerings, in particular, grabbed the keen attention of attendees thanks to its experiential booths. Wisenet P series AI cameras Wisenet Retail Insight v2.0 was one of them, providing business intelligence with age and gender-based people counting, heatmap and queue management features which are supported by Wisenet P series AI cameras. Meanwhile, the innovative Wisenet Transportation appliance (TAW-4000H16) is equipped with TMS (Transportation monitoring system) for the efficient operation and management of larger sites. It is crucial that video surveillance systems used in such facilities pose zero risk of exploding In addition, the company introduced a broad range of Middle East-specialized solutions, one being the 16CH NVR(XRN-1610G), which boasts a built-in modem that permits seamless video and status transfer to a control center using 3G or 4G, allowing operators to remotely monitor multiple devices across long distances in real time. Moreover, since heavy industrial facilities such as gas pipelines, petrochemical plants, and oil refineries are potentially explosive, it is crucial that video surveillance systems used in such facilities pose zero risk of exploding, while capturing high-quality footage at the same time. Wisenet explosion-proof cameras more than meet these requirements, via powerful networks and a protective stainless-steel housing enclosure. Pentabrid DVR It was the perfect setting for Hanwha Techwin to present its new multi-directional camera (PNM-9085RQZ), hybrid recording solution (Pentabrid DVR), and 8K resolution camera (TNB-9000) which are ideal for monitoring large spaces such as stadiums or airports, while the company also emphasized the significance of building trust through cybersecurity policies. The company’s global network was also highlighted, reiterating the importance of its R&D center and production based at the company’s South Korean headquarters as it expands its worldwide network to over 16,000 partners across 100 countries. “This year’s Intersec marked the beginning of not only a new year, but a new decade, too.
