Hikvision 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.

As the media often reports, the world of cybersecurity can be seen like the ‘Wild West’. There’s now a wide range of Internet of Things (IoT) devices connected to the web, making this a hot topic. Among these devices are security cameras. IoT devices are computers that use software that makes them vulnerable. As the famous cybersecurity evangelist Mikko Hypponen says, "If a device is smart, it's vulnerable!" Hypponen is right. On a daily basis, new vulnerabilities are found in software, regardless of the manufacturer. In 2019, more than 12,000 vulnerabilities worldwide were made public and reported as a CVE (Common Vulnerability and Exposure) in the National Vulnerability Database (NVD). Unfortunately, vulnerabilities are a given. What really matters is how a company deals with and resolves vulnerabilities. Cybersecurity vulnerabilities Awareness of cybersecurity vulnerabilities is vitally important to protect one, one’s business and the Internet Awareness of cybersecurity vulnerabilities is vitally important to protect one, one’s business and the Internet, but it’s also important to understand that a vulnerability is not synonymous with “backdoor”, and is not necessarily indicative of “cheap quality.” But there are companies out there that are embedding safeguards into their development processes to reduce the risks. One could see them as ‘Sheriffs’, taking steps to make this Wild West a little safer.  Hikvision ‘Secure-by-Design’ Manufacturers of IoT devices can significantly reduce these vulnerabilities during the production of devices Security cameras, like all other IoT devices, are vulnerable to cyberattacks. Fortunately, manufacturers of IoT devices can significantly reduce these vulnerabilities during the production of devices, using a process called ‘Secure-by-Design’. Implementation of Secure-by-Design requires a commitment on the part of the manufacturer’s management team and a serious investment in resources and technology, which can result in a longer production process and a higher cost of the IoT device. Cost is often the reason why some IoT device manufacturers do not use Secure-by-Design (and are indeed cheaper). Hikvision is a producer of IoT devices that takes security and privacy very seriously and has implemented Secure-by-Design in its production process. Management supports this process and has even set up a dedicated internal cybersecurity structure charged with product cybersecurity. This group is also the central point of contact for all other cybersecurity matters. Product testing Hikvision Security Development Life Cycle (HSDLC) is an essential part of Hikvision's cybersecurity program The Hikvision Security Development Life Cycle (HSDLC) is an essential part of Hikvision's cybersecurity program. Cybersecurity checks take place at every stage of product development — from concept to delivery. For example, product testing takes place during the verification phase, the company also regularly invites well-known security companies and public testing platforms to conduct penetrating testing. There is no guarantee if Hikvision products are immune to hacking, but the HSDLC is a testament to a manufacturer that makes every effort to produce products that are as cyber secure as possible. In addition to the Secure-by-Design process, Hikvision opened a Source Code Transparency Center (SCTC) lab in California in 2018, being a lab to open such a center. At this center, U.S., the Canadian government and law enforcement agencies can view and evaluate the source code of Hikvision IoT devices (IP cameras and network video recorders). Hikvision firmware Hikvision has a Vulnerability Management Program in place when a vulnerability is discovered It’s important to emphasize that no product is 100 percent secure. Hikvision has a Vulnerability Management Program in place when a vulnerability is discovered in a product. To date, vulnerabilities that have been reported to Hikvision and/or made publicly known, have been patched in the latest Hikvision firmware, and are readily available on the Hikvision website. In addition, Hikvision is a CVE CNA, and has committed to continuing to work with third-party white-hat hackers and security researchers, to find, patch and publicly release updates to products in a timely manner. These vulnerabilities are collected in the National Vulnerability Database (NVD) and are public. Hikvision recommends that customers who are interested in purchasing security cameras inquire about a manufacturer’s cybersecurity practices and if they have an established Vulnerability Management Program.  Cybersecurity questions to consider The cybersecurity of IoT devices is a topic that needs to be addressed in a serious way and it should play an essential role in the product development process, beginning at the concept phase of an IoT product. This requires time, investment and knowledge. Consider the following questions: Trust on the manufacturer of a low-cost security camera Manufacturer with a dedicated cybersecurity organization Manufacturer on handling the vulnerabilities These are the questions that everyone should ask themselves when making a purchase, be it a camera or any other IoT product. Cybersecurity practices There is no absolute 100% guarantee of security, but Hikvision has practices to ensure the cybersecurity for its cameras. Cooperation, with its customers, installers, distributors and partners, and full transparency are key elements to successfully secure IoT devices. When one reads cybersecurity news, one is invited to look beyond the headlines, and really get to know the companies that produce the IoT devices. Before one buys a security camera or any IoT device, it is advisable to check out the manufacturer’s cybersecurity practices, look for a company with a robust vulnerability management program, a company that aligns itself with Secure-by-Design and Privacy-by-Design and a company that employs cybersecurity professionals who are ready and eager to answer one’s questions. One may remember that there are Sheriffs out there, as well as bandits.

Businesses are now gradually reopening in many countries, and people can return to restaurants, office buildings, and public spaces. A safe reopening process will rely heavily on effective public health strategies, including increased testing for the virus, social distancing, occupancy restrictions, and cleaning and disinfection activities. In many countries, temperature measurement and the wearing of masks have been commonly made mandatory in both business and public environments. While social distancing and occupancy restrictions are considered necessary in public areas such as shopping malls and transportation hubs, workplaces like office buildings and industrial parks are looking for solutions featuring authorized entries with confidence. In lifting the restrictions for businesses and public areas, innovative video technologies can also help organizations meet and exceed health guidelines for safe and effective reopening. Temperature screening at entry  The Centers for Disease Control and Prevention (CDC) in the United States, a very well-known public health organization, have issued new guidelines for reopening offices. The CDC advises daily health checks including temperature screenings before employees enter a workplace. To achieve this, security cameras equipped with thermographic video technology can be an effective tool for rapid and safe initial temperature screening. Applications include, for example, schools, industrial parks, hospitals, office buildings, malls and hotels, etc. Hikvision’s temperature screening solutions offer various product types including installed thermographic cameras, handheld thermographic cameras, metal detector doors, and MinMoe access terminals that can be flexibly deployed for a wide range of applications. Video monitoring for mask compliance Wearing masks is recommended as a measure to contain respiratory droplets and protect the general public. Masks are also commonly included in worldwide health guidelines towards reopening. Store managers also need to identify and mitigate areas where shoppers may congregate Hence, compliance with this guideline has become crucial to many organizations. Video technology can help monitor the use of protective masks in clever and unobtrusive ways. AI algorithms can detect whether a person is wearing a mask. The system then triggers a pre-defined action if no mask is detected, such as, for example, a voice prompt or a link to an access system to deny entry. This provides a simple way to monitor the situation, or even to remind people of the rules. Hikvision’s thermal and AcuSense cameras, as well as MinMoe temperature screening terminals are equipped to detect masks. A specialized interface on Hikvision’s DeepinMind NVRs can also be used to visually display temperature and mask status together, making monitoring much easier. Crowd density control Social distancing plays an important role in “flattening the curve” in the spread of the coronavirus. These technologies use people counting and 3D modeling to measure the distance between people accurately In various countries, the recommended physical distancing might differ slightly, but maintaining a distance of a meter or more (3-6 feet) will remain a key recommendation of health authorities. In addition, store managers also need to identify and mitigate areas where shoppers may congregate, so as to ensure safe shopping spaces. Technologies incorporating social distancing and occupancy detection can be put into places like these to assist the process. Hikvision Flow Control Hikvision’s Flow Control system utilizes highly accurate people counting technology. A clear, dynamic display and real-time alerts ensure pre-defined capacity thresholds are never exceeded, even in locations with multiple entrances and exits, such as, for example, shopping malls and supermarkets. Video solution provides the necessary features and functionalities to assist with the process of social distancing A digital sign can be integrated at entrance areas to display real-time occupancy data, as well as temperature and mask information, letting customers know when it is safe to enter premises. In waiting areas such as cash registers in supermarkets and indoor ATMs in malls, Hikvision’s video solution provides the necessary features and functionalities to assist with the process of social distancing. These technologies use people counting and 3D modeling to measure the distance between people accurately. The exact measurement can be adjusted, well within the social distancing minimum separation guidelines. Touch-free access control  Schools and workplaces have previously made use of traditional access control and time attendance systems such as ID card swiping, PIN codes, or fingerprint scans, which require staff and students to frequently touch shared surfaces. This only increases the risk of spreading infection. With touch-free access control terminals, organizations can not only eliminate the risk, but greatly enhance their daily operational efficiency. Hikvision’s MinMoe temperature screening terminals unify temperature screening, mask detection, and access control & time attendance in one model. The system only grants entries when the guidelines are met, which is particularly useful in highly-populated workplaces like industrial parks and office buildings.
