ONVIF Profile T And H.265: The Evolution Of Video Compression
ONVIF Profile T And H.265: The Evolution Of Video Compression

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.

HD Over Coax Provides Cost-effective Video Surveillance Upgrade
HD Over Coax Provides Cost-effective Video Surveillance Upgrade

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.

Video Surveillance Must Modernize In Storage, Recording And On-Demand Access
Video Surveillance Must Modernize In Storage, Recording And On-Demand Access

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.

Dahua Technology USA Announces Adding Advanced 5MP Smart Motion Detection IP Cameras To Its Lite Series
Dahua Technology USA Announces Adding Advanced 5MP Smart Motion Detection IP Cameras To Its Lite Series

Dahua Technology USA Inc., a provider of advanced, video-centric, smart IoT solutions, has introduced a new selection of 5MP IP cameras in its cost-efficient Lite Series, incorporating Smart Motion Detection (SMD) technology for ease of set-up, improved accuracy, and fewer false alarms.  Smart Motion Detection (SMD)  SMD uses an advanced algorithm to differentiate human and vehicular shapes within a scene and send alarms only when a person or vehicle is detected. SMD can be enabled with just one click, allowing the camera to analyze all motion within its view. The camera then filters motion-activated objects depending on what the user wants to see, making searches faster. “Compared with traditional motion detection where lights, animals, rain, and tree movement tend to cause false alarms, Dahua’s SMD feature gives the user highly accurate motion detection with fewer false alarms. No more annoying alarms with useless information,” remarked Jennifer Hackenburg, Senior Product Marketing Manager at Dahua Technology USA. SMD N53A series cameras The SMD N53A series cameras can be paired with Dahua N52 and N54 Series NVRs with upgraded firmware The SMD N53A series cameras can be paired with Dahua N52 and N54 Series NVRs with upgraded firmware to take advantage of the complete SMD solution. With this solution, users can tailor real-time push notifications according to what’s relevant to them and conduct quick target searches based on object classification, date and time. The SMD feature will expand to other models later this year. Quick Target Search, a playback feature, extracts and classifies images of humans and vehicles from video data, making it easy for users to review and retrieve historical information. The SMD cameras are well-suited for environments where limited resources mean fewer onsite security guards. Integrated with IR and Starlight technology The SMD N53A Lite Series offers fixed and vari-focal options in eyeball, dome and bullet-style form factors. These cameras include additional, advanced features that further maximize users’ Return on Investment (ROI), such as Starlight technology for ultra-low-light scenes, True Wide Dynamic Range (120dB), integrated IR, and perimeter protection for customized intrusion detection and tripwire functionality. Additionally, the Smart H.265+ codec reduces bandwidth and storage requirements without compromising image details. “The new SMD cameras represent advanced edge technology that truly reduce false alarms and provide peace of mind,” added Hackenburg. “We’re pleased to be able to provide SMD based on customer needs and help them bring additional value to the end users.”

GSX 2019 Day One Review: Lots Of ‘Newish’ Products To See On The Show's Busy First Day
GSX 2019 Day One Review: Lots Of ‘Newish’ Products To See On The Show's Busy First Day

GSX 2019 got off to a jaunty start Tuesday. The show was humming with activity much of the day, and most exhibitors said they were pleased with the numbers and types of potential customers visiting their booths. There seemed to be less emphasis on product introductions than at the ISC West show in the spring (although there is much that is on the new side), while the trend toward system sales is continuing. Here's a review of Day 1 from the show floor. Dahua continues to educate market  “Traffic-wise, the show is better than last year,” observed Tim Shen, Director of Marketing at Dahua Technology USA, at midday on Tuesday. “We met more people from Latin America,” he added. Shen theorized that Chicago is at the center of a larger territory of customers than last year’s location (Las Vegas).Dahua’s presence at the show makes a statement: “We’re still here" Dahua has faced some negative publicity in the last year since they were banned from procurement by U.S. government customers by the National Defense Authorization Act (NDAA). Dahua’s presence at the show makes a statement, says Shen. The statement is “We’re still here.” Shen said only one visitor to the Dahua booth even mentioned the NDAA on the first day of the show, and the visitor was misinformed about the provisions and implications of the law. “There is a lot of misinformation,” he says. “We need to continue to educate the market.” Facial recognition, video metadata, and people counting New at the show is the Dahua Analytics+ line of cameras that feature more in-depth analysis of data such as facial attributes, video metadata, and people counting. For example, the cameras can identify 128 points in a face, with an additional 256 attributes analyzed by the back-end recorder. Analysis can provide information such as age and gender, which can help a retailer analyze the demographics of their customers, for instance. Dahua is also adopting some of its consumer line of products for sale through the commercial channel. These include a flood light camera, a 2-megapixel WiFi camera and a doorbell camera. The products might be used outside of a retail store, for example, to complement Dahua commercial cameras that are used inside the store, says Shen. Dahua previewed a new multi-sensor camera that also includes a speed dome. The multi-sensor component combines eight views, each 2 megapixels, for a total of 16 megapixels. Below the multi-sensor camera is mounted a speed dome that can zoom in on regions of interest in the larger multisensor view. The camera will be launched in the fourth quarter. The show was humming with activity much of the day, and most exhibitors said they were pleased with the numbers and types of potential customers visiting their exhibits ACRE reports continued North American growth “The industry’s momentum will continue to grow,” predicted Joe Grillo, Principal of ACRE. New areas such as cloud and mobile credentialing have the fastest growth rate, but are starting from a much smaller base, he said, so momentum in those categories will take time.ACRE sees continued rapid growth with no slowdown in the North American market Grillo noticed the first morning of GSX was busy, although there was a bit of a lull at midday. In terms of the business outlook, Grillo sees continued rapid growth with no slowdown in the North American market, although there have been some negative elements creeping into the outlook in Europe. Cybersecurity concerns in access control I caught up with Grillo at the booth promoting RS2, a Munster, Ind., access control company that Acre acquired last May. It is the only Acre company that is exhibiting at GSX. RS2 is one of two access control companies acquired by Acre in the last year — the other was Open Options, Addison, Texas. Grillo said the two acquired companies are complementary, especially in terms of their sales channels and geographic strengths. Although both are national companies, RS2 tends to be stronger in the Midwest, while Open Options sales emphasis is centered in Texas and emanates to the rest of the country. Concerns about vulnerabilities are a growing issue in access control, said Grillo, and more large endusers are conducting penetration testing of systems. The industry should welcome the scrutiny, he added. Cybersecurity also represents an business opportunity in access control, noted Grillo. Concerns about the vulnerabilities of legacy technologies such as 125Khz proximity cards and the Wiegand protocol will likely accelerate the pace of companies upgrading their access control systems There seemed to be less emphasis on product introductions than at the ISC West show in the spring (although there is much that is on the new side) Eagle Eye Networks and cloud-based VMS Ken Francis of Eagle Eye Networks had already realized some new client opportunities during the first day of the show, although he was not optimistic at the outset. In contacting potential clients to meet at the show, he had heard that many were not attending. Among Eagle Eye Networks’ news at the show is full integration of body-cams into their cloud-based video management system. “It’s the most unique thing happening from a video management perspective,” Francis said. Previously, if someone needed a video clip from a body cam, they had to use a separate software system. Five years from now, at least 80 percent of all VMS systems will be cloud-managed" Francis continues to be bullish on the subject of cloud adoption of video management and made a bold prediction: “Five years from now, at least 80 percent of all VMS systems will be cloud-managed.” Eagle Eye Networks is doing its part with “rocket growth” that is reflected in an increase of company employees from 27 to 165 or so. Economies of scale have enabled Eagle Eye Networks to lower subscription prices by up to 45 percent. Genetec's release self-service PIAM system Many of the “new” products at GSX 2019 are slight variations on what was introduced at ISC West last spring. An exception is Genetec’s introduction of ClearID, a self-service physical identity and access management (PIAM) system that enforces security policies while improving the flow of people within the organization. The new system is integrated with the Genetec's Security Center Synergis access control system. PIAM systems have historically been customizable, complex to install and costly, which is why a lot of companies have not used a system. Genetec’s differentiator is that it is an off-the-shelf, out-of-the-box solution for a broader base of customers. “We scanned the market and found a lack of off-the-shelf identity management systems,” said Derek Arcuri, Product Marketing Manager, Genetec. “Targeting the mid-market, we are providing an accessible, ready-to-go cloud-based system that is ‘baked’ for the average company but can be integrated and expanded to include other systems.” The trend toward system sales at the show is continuing ClearID will simplify operation for the security department, which was previously tasked with a lot of administrative work in response to various departments. ClearID “pushes down” the authority to use the system to stakeholders (such as IT and/or facilities directors) and provides  a system they can use themselves without involving security. “It empowers stakeholders and employees to work directly through the system rather than going through security,” says Arcuri. “It gives employees access based on stakeholder policies and improves the flow of people through an organization. The security director is relieved of administrative work and can work on ‘real’ security.” I saw some other things today, too, which I will share in a future GSX article... And more about the show tomorrow.

Florida Cattle Ranch Installs Dahua PTZ Cameras For Its Bald Eagles
Florida Cattle Ranch Installs Dahua PTZ Cameras For Its Bald Eagles

Video surveillance is used for more than just safety and security: users are discovering that high-resolution images and user-friendly features make surveillance cameras a valuable asset for all sorts of applications. A cattle ranch in Manatee County, Florida found that a Dahua PTZ was the perfect way to observe eagles without disturbing their habitat. Dahua PTZ Cameras  When Hurricane Irma pummeled Florida in 2017, Victoria and Nicholas, a pair of American bald eagles, watched their nest get destroyed. Undeterred, they began building a new nest in a tree right next to the old one. The ranchers on whose property the eagles lived were so inspired by this show of dedication that they decided to install cameras nearby to share the eagles’ story with the world. They reached out to Jens Buff, security consultant with Rapid Security Solutions, for support, and he contacted Dahua. Dahua donated a 4MP 30x IP PTZ, which was mounted to a tree in order to observe the nest up close. Dahua donated a 4MP 30x IP PTZ, which was mounted to a tree in order to observe the nest up close But disaster struck yet again! In 2018 “an unnamed storm, unexpected and unseasonable, blew through our area with pounding rain and ferocious winds,” stated the Eagle Country YouTube page. “Sadly, the eagles’ nest was blown to the ground in pieces again! We wondered if they would relocate, but this was Nicholas and Victoria. The very next day they began to rebuild. The cameras we placed after Irma were not destroyed and we are able to watch this incredible story continue.” Smart IR And Day/Night Surveillance Dozens of YouTube videos, as well as a live feed, give viewers a rare glimpse into the day-to-day lives of these majestic birds. Whether they’re incubating eggs, eating dinner, cleaning house, or fending off intruders, their activities are captured in clear video both day and night. The camera’s true day/night IR cut filter and Smart IR allow for crisp nighttime images without “whitening out” as the eagles get close to the camera. True WDR preserves the image in the direct sunlight that’s unavoidable at the top of a tree in the Sunshine State. The easy-to-use PTZ features let the ranchers follow the eagle’s actions without bothering them by manually repositioning the camera. “Dahua’s PTZ was the perfect choice to view one of life’s most beautiful creations living in nature,” Mr. Buff remarked.
