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 Standardisation organisations 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 recognises 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 analogue, 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 analogue 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 analogue systems. Longer cables grant transmission for up to 1600 feet, double the distance of standard analogue 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 analogue 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 packetise 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, analogue 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 utilise 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, analogue or IP, can be connected through one DVR. For many end users with legacy analogue 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 unauthorised 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 analogue 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 unauthorised 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, maximising 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 minimised, 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.
Building on its ‘See More in Smarter Ways’ campaign, VIVOTEK, the global IP surveillance solution provider, has introduced two new H.265 Deep Learning fisheye cameras, the FE9191 and FE9391-EV. These two professional day-and-night 12-megapixel fisheye cameras provide 360-degree surround views with zero blind spots and come armed with VIVOTEK’s self-developed Deep Learning technology, Smart 360 VCA. This technology includes intrusion detection, crowd detection, and loitering detection. Such capability transforms these surveillance cameras from capturing devices to advanced notification instruments and in the process significantly reduces false alarms. Protecting area from unauthorised entry The Intrusion-Detection function is designed to protect any specific area against unauthorised entryPowered by VIVOTEK’s people tracking AI engine, the FE9191 and FE9391-EV are smart-fisheye cameras with Smart 360 VCA technology. The Intrusion-Detection function is designed to protect any specific area against unauthorised entry. The Crowd-Detection function can detect and calculate how many persons occupy a given space and triggers alarms when capacity is reached in that area. Finally, the Loitering-Detection function can detect a person or people remaining too long in any selected area. Further enhancing their functionality, both cameras are embedded with Trend Micro’s anti-intrusion software to provide users with higher levels of network protection. Working together, these advanced features ensure the new fisheye cameras are both highly intelligent and robustly secure. Minimising false alarms “In the past, surveillance cameras were built to meet security demands. However, how one minimses false alarms remains a challenge in the industry,” said Shengfu Cheng, Director of Marketing and Product Development Division, VIVOTEK Inc. “Thanks to the development of AI, the FE9191 and FE9391-EV smart-fisheye cameras are programmed to learn to differentiate between the motion of people and objects. With the Smart 360 VCA technology, our fisheye cameras extend beyond purely for security applications, instead becoming intelligent devices to analyse how many and how long people stayed in a specific area. We are committed to helping retailers and users improve business management efficiency while securing their assets with accurate identification.”
In today’s technology-driven markets, a platform is a business model that connects producers and consumers in an interactive ecosystem. Some examples of platforms are Uber and Airbnb, which have disrupted and transformed traditional markets. Isn’t it time to deploy the platform model in the physical security industry? That’s the goal of the Open Security & Safety Alliance (OSSA), a non-profit organisation. Interactions and exchange The book ‘Platform Revolution’ defines a platform as ‘a business based on enabling value-creating interactions between external producers and consumers.’ The description continues: ‘The platform provides an open, participatory infrastructure for these interactions and sets governance conditions for them. The platform’s overarching purpose is to consummate matches among users and facilitate the exchange of goods, services, or social currency, thereby enabling value creation for all participants.’ Platform for security and safety solutions OSSA’s plan is to build a common standardised platform for security and safety solutions. Founding members are Bosch Building Technologies, Hanwha Techwin, Milestone Systems, Pelco and VIVOTEK. Anyone can join the alliance, which is growing rapidly and gaining traction as the Internet of Things (IoT) expands. OSSA’s plan is to build a common standardised platform for security and safety solutions OSSA members could be found throughout the recent ISC West show in Las Vegas, and a social event after hours at the show brought them together and set the tone for development to come. A Technology Stack “We want to create an ecosystem, define a common market approach and open new market opportunities,” says Johan Jubbega, OSSA President. “We want to go from a product business to a platform business. It’s better for us and better for the end-users.” OSSA seeks to develop a specification for a common Technology Stack to cater to innovation and reduce fragmentation within the security and safety market, according to OSSA. Its mission is complementary to organisations like ONVIF. Video information and low friction The video surveillance industry creates vast amounts of information in the form of video, but typically less than 1 percent of that data is used by today’s video surveillance systems – think about that one or two frames of video among thousands that might be used to solve a crime, for example. The rest of the data remains unused, and yet the potential value of the data is huge. OSSA seeks to create a platform to leverage the value of the data. “If we don’t unlock that value in our industry, someone will do it for us,” says Jubbega. OSSA is developing a vendor-agnostic operating system that simplifies low-level device integration and standardises elements such as cybersecurity and security update patches Among the important elements in developing the platform are to create a level of trust among all the stakeholders involved, and to lower the ‘friction’ involved in participating in the platform. “We want to make it easy and fun to do business with anyone who joins the platform,” says Jubbega. “By taking away the friction, we will create scalability.” System-on-chip Development of customisable system-on-chip (SoC) components in today’s video cameras provide the capacity to host a variety of ‘apps’ to expand system functionality and leverage the value of data. OSSA is developing a vendor-agnostic operating system that simplifies low-level device integration and standardises elements such as cybersecurity and security update patches. Building on top of that operating system, vendors can create new levels of differentiation. “Our purpose is to start from a common business model to spur innovation and add value for users,” according to OSSA. Cybersecurity and data protection SAST is creating the operating system and setting up the IoT infrastructure to make apps available Simply speaking, app developers can use the standard operating system to build new functionalities that can easily be ‘loaded’ on cameras and sold in an ‘app store’ scenario. Security and Safety Things (SAST), a Bosch startup and member of OSSA, is creating the operating system and setting up the IoT infrastructure to make the apps available. Development of these elements is happening concurrently with the evolution of OSSA. “We offer you an opportunity to come with us on this journey,” Jubbega told attendees at the ISC West social event. “We want to have a common approach to tackling cybersecurity and data protection – to raise the bar in the industry. You can still differentiate, but from a higher base.” OSSA members who exhibited at ISC West included Anixter Inc., Bosch Building Technologies, Hanwha Techwin, Milestone Systems, NetApp Inc., Pelco, SAST, Socionext Inc., United Technologies and VIVOTEK Inc.
