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.

OPTEX has launched its new Intelligent Visual Monitoring solution in the UK and Ireland, powered by CHeKT - a hardware and software solution that takes separate intruder and CCTV technologies installed on the same site, but acting independently, and ‘bridges’ them to create one, seamless, integrated visual monitoring solution. Monitored intruder alarms can now be visually verified within seconds, without impacting the integrity of the technology installed, or its Grade. When an alarm occurs, a signal is instantly sent to the Alarm Receiving Center (ARC) whose operator can view images pre and post the alarm event as well as the live view via a dedicated portal to determine whether the alarm is genuine. Intrusion sensors OPTEX Bridge is the hardware device that physically connects the intrusion sensors and IP cameras Camera locations can be overlaid with a map of detection zones, thus helping the ARC operator to quickly and easily ‘see’ where the incident has occurred and take the appropriate action. Images can also be sent directly to the customer’s handheld device for further verification if, for example, the alarm is genuine, but the ‘intruder’ is known to the customer or has a legitimate reason for being on site. The OPTEX Bridge is the hardware device (gateway) that is physically connecting the intrusion sensors or the panic buttons and IP cameras on site. It provides a complete audit trail of activity and can detect when a camera is not working (i.e. when it has dropped out of the network), and report the fault, thus ensuring security is not compromised. Intruder alarm technology It can also communicate via a gated Cloud portal with the ARC in the appropriate ‘language’, regardless of the make or manufacture of the monitoring technology installed, or the protocols with which it operates. It will, in effect, work with virtually any intruder alarm technology and any ONVIF camera to deliver one seamless visual verification solution. The ARC software needs to be compatible, and many of the major ARC software platforms are already integrated. Whereas the monitoring of intruder alarms through an Alarm Receiving Center (ARC) is generally accepted best practice, CCTV monitoring remains slow to take hold. Part of the problem has come down to money; larger sites such as major depots and warehouses with constant activity 24/7 can clearly benefit from a fully functioning CCTV system monitored through a dedicated Remote Video Response Center (RVRC). Visually verified alarms Cloud-hosted platform also allows a stronger collaboration between the ARCs and the home/business owners Smaller sites, while they would benefit from visually verified alarms, would struggle to justify the investment of a full-scale RVRC solution. ARCs now have the ability to provide a visual verification service to residential and commercial sites without a substantial investment in time or money; the Bridge can be installed and working within the hour. The Cloud-hosted platform also allows a stronger collaboration between the ARCs and the home/business owners by having the ability to share video clips to confirm the alarms while respecting any privacy guidelines through its bespoke privacy feature that only end-users can release. Early warning solution Masaya Kida, Managing Director of OPTEX EMEA says by installing the OPTEX Bridge, sensors and cameras combine to deliver a secure, reliable and effective early warning solution, detecting and reacting to an intrusion before a potentially damaging and costly event has occurred. “It is also invaluable to those who need police response and may have lost their URN (Unique Reference Number); a visually verified alarm will put them back on police response. For the installer, meanwhile, it provides them with the opportunity to re-engage and adds further value to the customer with the ability to seamlessly integrate with existing systems and technology across single or multiple sites.”
Multiple Construction sites in the Albuquerque area are managed by Shumate Constructors, Inc., an Albuquerque, New Mexico-based construction contractor, that is also renowned for building educational facilities. In addition to building schools from the ground up, Shumate Constructors completes school additions and remodels. Construction site thefts Three years ago, the company began having problems keeping thieves out of its construction sites during non-working hours. Unwatched construction sites are hot beds for a variety of thefts - from copper pipes and wire to hand tools to heavy-duty machinery. The loss of machinery, such as front-end loaders, would cost hundreds-of-thousands of dollars. Sometimes workers will arrive to a site in the morning only to find materials, such as copper pipe, gone along with their tools. Enhancing construction site security The sites also presented a challenge due to changing construction conditions The result is the loss of a whole day and sometimes multiple days of work. On top of the lost time, the contractor has to cover the cost of replacing materials, file an insurance claim for each theft and complete additional administrative paperwork that they weren’t planning to invest time in. The sites also presented a challenge due to changing construction conditions. Equipment or storage containers are delivered and removed, the sites are graded/re-graded and as sections of build were completed, tools, materials and supplies were moved to different areas. Flexible, reliable wireless solution At a contractor trade show a few years ago, Mark Shumate, President of Shumate Constructors met Dave Meurer, President of Albuquerque’s Armed Response Team. Meurer introduced Shumate to the idea of a flexible, reliable wireless solution that could continually monitor the entire site without the need to trench around the perimeter. “Mark [Shumate] was fed up with theft at his construction sites so we started to discuss some prevention ideas,” said Meurer, adding “I knew this was a great fit for the combined Inovonics transmitter and Optex sensor solution.” Optex sensors installed He further said, “At the Armed Response Team, we refer to this solution as the never sleeping, non-blinking eye. Shumate was not aware of any reliable solutions that could provide this type of theft prevention, but we explained that we were very confident in this application and he was definitely interested.” To install each combined sensor, the Armed Response Team attached the Optex sensors to a freestanding steel post with a base plate on it and deployed them throughout the site. This allowed the flexibility to be easily moved to accommodate site changes. Once installed, a signal was easily achieved. iSeries Optex/Inovonics sensors The amount of iSeries Optex/Inovonics sensors needed at Shumate’s sites vary The sensors in the combined solution often need to communicate as far as an entire city block and the perimeters can be several thousands of feet. The iSeries Inovonics/Optex solution was able to easily accomplish this feat. The amount of iSeries Optex/Inovonics sensors needed at Shumate’s sites vary. For some sites, it can be as few as a dozen, and others it can be as many as 30 or more. “Together, the products offer a great solution,” noted Meurer, adding “The Optex sensors can handle varying weather conditions and Inovonics’ wireless connectivity offers less signal drop and more consistent reporting signal than any of the other transmitters we’ve tried.” Efficient perimeter security solution “Between the perimeter technology by Inovonics and Optex, and the Armed Response Team’s follow-up, we have seen zero thefts for all projects since installation. With the integrated wireless solution, the construction sites are monitored on a real-time basis and immediately notify the Armed Response Team upon unauthorized access,” said Mark Shumate, President of Shumate Constructors. He adds, “We look at the perimeter security solution as a great investment. Annually, the cost of manpower, replacement of lost or stolen items and damage repairs could easily cost three times more than we spend on Armed Response Teams’ services with the Optex and Inovonics solution.”
