Hikvision, an IoT solution provider with video as its core competency, has launched a new 4G Solar Panel Kit for Standalone Security Sites. This will revolutionize the protection of remote assets in hard to reach places by proving a security camera that runs on solar power. The kit (DS-2XS6A25G0-I/CH20S40) includes a 4G camera, a solar panel, a battery, and a bracket, and can provide one-stop monitoring in remote environments. This means providers can deliver connected security to scenarios such as agriculture, animal husbandry, and forest fire prevention, as well as temporary monitoring of construction sites. The issue of having no power or network is no longer a problem, with the kit providing power to the camera through the solar panel and connectivity through 4G. It sends data to a communication station and then on to the security monitoring centre, where it can be managed using HikCentral Professional, and the HikConnect app. This means both monitoring and management activities, like viewing footage live, can be done remotely over the 4G network. Its lightweight design makes the kit easy to install, so just one person can install it with a pole mount. The IP67 level of protection makes it hardy against rain, and it also survives well against the strong winds often experienced in remote areas. The kit demonstrates long endurance, detecting power levels and automatically adjusting to power-saving mode when they are low. This means it can work continuously for seven days in cloudy and rainy weather when fully charged. Features include: 40 watt solar panel 20 Ah, built-in rechargeable battery 2 MP @ 30fps DarkFighter® for low-light imaging 8 / 4 / 8 mm lens options 30 m IR distance Built-in 4G (LTE-TDD/LTE-FDD/TD-SCDMA/EVDO) module.

Hikvision announced a brand-new addition to its DeepinView camera line: the Dedicated Subseries. This unprecedented new addition loads a batch of AI-powered deep learning algorithms into each unit, boasting stunning performance and cost-effective pricing. Enhanced AI capabilities Over the last few years, artificial intelligence (AI) has been applied in many ways in security markets. As technology advances, AI chipset performance has improved to enable massive computing power using various algorithms and contributing to multi-intelligence functionality and higher accuracy. The new Dedicated DeepinView Cameras are an example of these advances, incorporating several AI-powered deep learning algorithms in one unit. What’s more, these algorithms can be switched essentially putting 5 or 6 unique cameras in one housing. “Embedding switchable algorithms is a significant step for Hikvision to take in its AI product development. In a world of ever-changing technologies and functionalities, this approach creates great value for end users to try new technologies to ensure security, as well as to implement business intelligence and other applications,” says Frank Zhang, President of the International Product and Solution Center at Hikvision. “The benefits of our new offerings are numerous including reduced costs, improved efficiency, and speedy and effective incident response.” Switchable algorithms The Dedicated DeepinView cameras combine two product categories – the first is vehicle analysis where cameras combine automatic number plate recognition (ANPR) with vehicle attribute recognition. Attributes include the vehicle’s make, color, and direction of movement. Typical uses include installation at checkpoints of city streets and at entrances & exits of buildings or industrial parks. Models in the second category boast six switchable deep learning algorithms in one camera housing, including facial recognition, face counting, hard hat detection, perimeter protection, queue management, and multiple-target-type detection (detecting multiple targets and multiple types of targets at once). Accordingly, users can simply enable an algorithm manually for dedicated use, then later switch the algorithm as needed. Here is one example: hard hat detection. This algorithm can be used on construction sites to ensure safety and compliance. Specially-equipped DeepinView cameras can precisely distinguish a worker on the site wearing a hard hat from those without, and automatically deliver alerts when the hard hat violation is detected. Another example: in a retail setting, a face-counting function can be enabled to precisely count customers entering and leaving the store. Repeat customers and store staff can be automatically excluded in the process, helping store managers count new customers with precision. Flexibility among algorithms enables users to also switch among: Perimeter protection – to monitor outdoor areas needing security and deliver accurate alarms upon intrusions. Facial recognition – to grant authorized access to restricted areas in various organizations, such as school laboratories, archive rooms, and hospital pharmacies. Queue management – to better understand customer wait times, optimize staff levels, and enhance customer experience. HD clarity, day and night Equipped with Hikvision’s DarkFighter and LightFighter technologies, these cameras capture vivid and color images in extremely low-light environments or in scenes with strong backlighting where color and brightness balance is extremely difficult. Smooth Streaming mode further ensures a high-quality live feed. The Dedicated DeepinView Cameras are available in 2, 4, 8, and 12 MP resolutions for customers to choose from. More practical and deployable features Furthermore, metadata is supported to allow third-party platforms to receive data from Hikvision cameras for real-time video analysis or recorded into footage archives to enable rapid searching forensic evidence. Finally, these camera models also offer Vibration Detection for outdoor use, which detects and notifies users of vandalism.

Health organisations around the world have created the common awareness that maintaining a safe distance between people is one of the best practices we have to avoid being exposed to COVID-19 and in slowing its spread. As various countries and regions push to reopen businesses and relax stay-at-home orders, social distancing remains an ongoing requirement. More than that, crowd density information is also considered a significant reference in managing the "social distance" of workplaces, businesses and public spaces. Business owners are working hard to keep employees, customers and visitors protected. Dealing effectively with "density" – a new imperative for management and operations – complicates staffing and interpersonal interaction. Limiting the number of people to ensure safety In the current situation, public and private managers and authorities have to do more than ever before to keep people safe, and in many cases efficient calculation of customer traffic will be essential. Hikvision’s Flow Control Solution uses people counting cameras and digital signage, which provides a dynamic on-screen display to show users how many people are entering and leaving a building or an area, and sends real-time alerts in case pre-defined capacity thresholds are exceeded. These people counting camera utilise highly accurate 3D binocular stereo vision and Deep Learning algorithms, making complex counts easy, even in multi-door sites. More important, the Flow Control Solution can be easily and rapidly deployed. It is designed to be simple to use and highly accurate, with options to suit all potential application scenarios. In locations with a single entrance, one people counting camera can be installed at the entrance and connected to digital signage. For multi-entry scenarios, people counting cameras can be installed at each entrance and exit, equipped with I-Series NVRs or HikCentral to calculate numbers of people entering or leaving, so as to accurately provide real-time number data. Multiple entries and exits For example, a supermarket can install a clear and easy-to-understand, dynamic data number display at each entrance to provide real-time updates for people waiting to enter. An alert is generated when the pre-configured maximum is reached, and an audio alarm can be triggered if anyone attempts to enter before the numbers go below that threshold. At present, with expenses more critical than ever, users can use the Flow Control Solution to automatically monitor the situation, empowering businesses and possible reducing the required number of security guards and other resources. Maintaining a safe social distance in public In areas where crowds are unavoidable, such as cash registers in supermarkets and the ticket kiosks at public transportation hubs, managing distances between people queuing (standing in line) is also critical. Authorities in various locations have established specific guidelines and legislation in this area, balancing needs and risks for citizens. Hikvision Dual Lens Cameras (DS-2CD6825G0/C-I(V)(S)) help retail stores and other businesses measure social distancing, and its advanced 3D binocular stereo vision and deep learning algorithm can be configured to trigger alarms according to local regulations and requirements. Users can set the minimum contact distance threshold needed; when the distance becomes less than this pre-set threshold, an instant alarm and popup will appear with audio and video linkage. And there’s more Alongside the Density Control Solution, Hikvision also offers a Mask Detection Solution. This technology ensures that anyone entering a premise is wearing a face mask when they are required to do so. Those without a mask will not be granted entry. The Mask Detection Solution can be delivered in a variety of formats depending on user needs: added to a specialty camera or a Hikvision DeepinMind NVR for users with existing camera systems, integrated into Hikvision’s Temperature Screening Thermal Solution, or as part of a MinMoe door access unit with built-in face detection technology. Entry can be denied if a mask is not worn and/or an out-of-range skin-surface temperature is detected. As businesses begin to emerge from lockdown, they need to find ways to reduce risks of furthering the spread of the virus. This affects whole populations and all their normal activities – from getting coffee on the way to work and boarding public transportation, to shopping and eating out. But there are some technologies that they can turn to – innovations that will facilitate a “new normal” and keep people safe. And Hikvision will be there, every step of the way.

Effective video surveillance of an area requires clear, sharp and hi-res images so the operator has complete situational awareness in any weather or light conditions. Cameras continuously film monitored areas and so acquire an abundance of data-rich images. The complexity and volume of information can cause operators to lose attention, making the whole system vulnerable to mistakes and false alarms. It is now possible to reduce these critical issues, which exponentially increase a security system’s risks and operating costs, by using video analysis applied to surveillance cameras. Analysing video footage has become essential to the intelligent management of images and alarms. It ensures that potential intrusions that could threaten people, goods or property are detected and prevented. Videotec is proud to announce that is has released a “robust and smart” video analysis technology, integrated into ULISSE EVO cameras, that offers an end-to-end solution for preventative detection of intrusions in outdoor monitoring applications of critical infrastructures, industrial sites and perimeters. Videotec Analytics is the result of more than 10 years of research and design, carried out by a team of R&D professionals, cooperating together with prestigious international universities and research centres and is designed to be extremely reliable and proactive and be simple to configure and easy to use. Outdoor surveillance specialists The ULISSE EVO camera with Videotec Analysis technology comprises robust algorithms for accurate PTZ detection and precise and smooth auto-tracking, even in the most adverse external environmental conditions. The operator will have complete situational awareness no matter the circumstances. The Advantages of Videotec Analytics ULISSE EVO with Videotec Analytics means: Maximum preventative anti-intrusion efficiency A reduction in human error and therefore Reduced storage space needed: only necessary footage is recorded. Optimal external operation in the most critical and complex atmospheric conditions The GeoMove&Track function allows two ULISSE EVO to communicate with each other through intelligent language, create advanced actions, and perform a tracking based on the geo-coordinates of the target. It gives the immediate benefit of having a complete, turnkey positioning and tracking solution, guaranteed by Videotec. Unbeatable detection performance even at long distances, thanks to the analysis of detail-rich high-definition images. Reduced time and effort needed to monitor, detect and search the recordings for anomalous events. The resulting security system is highly efficient, reliable and convenient. How does Videotec Analytics work? Every time there is an alarm, the auto-tracking automatically activates and event metadata is sent to the VMS via the ONVIF protocol. Simultaneously, the security operators are then alerted and recording starts. The ULISSE EVO keeps the moving target at the centre of the frame and zooms in on the target to make recognition easier. The metadata sent to the VMS system can be used to frame the target with a bounding box for clear identification of the subject or it can be used to activate alarms or begin recording. How to configure Videotec Analytics A simple initial configuration allows ULISSE EVO to detect an object or person present in a sensitive area. Depending on the rules set by the user, an alarm is displayed and auto-tracking activated if an object enters, exits, or appears or stops more than allowed in an area. Thanks to an intuitive management interface, up to ten rules for each pre-set can be configured quickly. Any violation of these rules will activate auto-tracking and other scheduled actions. line crossing (the target crosses a line in one direction or multiple directions) entering/leaving area (the target enters or leaves a specific area) appearing in area (the target appears in a specific area loitering (the target stays in a specific area longer than a defined time) target classification (for people and vehicles) function of detection mask (disables detection activity in a part of the image) Function of video tampering detection (an ONVIF alarm occurs if the camera lens is obscured or covered to block the view) Calibration and target classification with Videotec Analytics The operator can calibrate, via a very intuitive web interface, the scene’s point of view, so it is possible to render the targets in 3D. Targets can be put into three categories: generic object, person, vehicle. Targets will then trigger an alarm based on their size and so false alarms as a result of irrelevant objects appearing in the frame are drastically reduced. Videotec know-how and technology Videotec’s ULISSE EVO range with Video Analytics offers an integrated professional outdoor solution that is more robust and performs better than any other PTZ on the market. Videotec puts its all-in-one products through hundreds of validation tests in order to guarantee optimum robustness and reliability. As well as this, the electronics and networking are chosen from the industrial and automotive sector in order to ensure operation in the most critical environments. Mechanics, electronics, positioning, networking, software, video analysis algorithms and firmware are developed end-to-end by Videotec’s own R&D team. Videotec bases the development of its products on the concept of cyber-sustainability, where support, updates and training about the products span an interval that is larger than each single product lifecycle and assist integrators and customers keeping their systems protected. ULISSE EVO therefore offers Videotec’s guarantee of being a reliable, cyber-safe, future-proof platform that is easily integrable with third-party products.
Contact traceability reporting is the latest feature to be added to ACT365, the cloud-based access control and video management system. The latest feature to the award-winning cloud system helps system-users adhere to new health and safety standards due to COVID-19. For instance, thanks to contact traceability reporting, users of ACT365 can now successfully: Track potentially infected employees and the doors they enter. See people who entered the same door/room. Contact any employee with details from an exported Excel report via ACT365. Monitor doors that require cleaning or disinfecting. ACT365’s contract traceability reporting helps businesses create a safer and cleaner environment for their staff. System users can now remotely monitor their office from anywhere in the world, including tracking international travelers to their site. How it works: Once an employee tests positive for COVID-19, the office manager can trace their movements within the building during a filtered timeframe. This can be achieved by entering the employee’s cardholder ID details into ACT365 and generating a contact traceability report. This report can be downloaded to Excel, and the manager can identify all doors the infected employee entered in the past two weeks. Other employees who also entered those rooms can also be traced and contacted to inform them to self-isolate. Affected doors can also be identified and cleaned.

Flow control to support social distancing As the world moves to the new normal and measures are lifted, governments have put in place restrictions to support social distancing and avoid any new spread of COVID-19. Managing and controlling the numbers and access of people in and out of stores and offices, or indeed any building open to the public is crucial in supporting social distancing measures. The importance of real-time data accuracy Measuring occupancy as it happens with immediate updates of the people count is therefore critical as could lead to overcrowding, making social distancing hard to control and causing a risk to safety. The data needs to be gathered in real-time and transmitted instantly to the integrated occupancy software platform in order to give an exact picture on how many people are in a store, room or a specific area of a building. Another aspect to consider is the precision in the count of people going in or out of a store, making sure there are no errors in the count that over time accumulate minimising the reliability of the information, and which could again create unsafe situations or impact negatively on the store sales, if for instance no access was allowed based on incorrect reporting that occupancy threshold had been reached. The OPTEX Akribos VC-1020 is a real-time and multi-directional indoor people counter that can provide more than 97% accuracy. It ignores trollies and baskets and manages groups of individuals by tracking the direction of every individual, even complicated movements such as people turning back or standing still. Now featuring MQTT protocol, the Akribos sensor can be integrated with third party analytics software transmitting instantly the data gathered which can then be used to create key-performance reports, dashboards and visual displays to control occupancy levels. A long-term solution for businesses Many businesses and retailers are using their security staff to manage access and control queue volumes and as such, installers have an opportunity to become the principal point of contact for bringing new solutions regarding occupancy level and social distancing. The solution with OPTEX Akribos solves the issue created by the pandemic, but also solves the ongoing challenge of efficiently and accurately monitoring occupancy levels within a busy working or retail environment. The analytics and people traffic reporting can help retailers manage their staff and product placement better, and in the office to have a more efficient building management based on occupancy level.

This zoom lens has the resolving power to support high pixel counts and can support 1.8µm pitch image sensors. It promises three desirable characteristics: super-wide-angle support for high pixel counts, and high performance. With an angle of view of over 100°, this 5 mega-pixel lens is a new type of board mount zoom lens. The lens, moreover, not only offers 5 mega-pixel picture quality under visible light, but the same high level of quality is accomplished with near-infrared light conditions. Day or night, this lens, for the new age ensures high-resolution and high-performance monitoring with no compromise of picture quality. Tamron will lead the market for high-definition security with the newly developed zoom lens supporting 5 mega-pixel and near-infrared lighting. Key features 1. Super-wide-angle, high-picture-quality 3.5 x zoom lens for PTZ Achieves a wide 123.1° angle with 1/2.7” sensors (16:9) and 100° angle with 1/3” sensors (4:3). Enables wide-area monitoring with a single camera. 2. Maintains 5 mega-pixel high performance even in near-infrared light Achieves 24-hour, 5 mega-pixel monitoring without loss of picture quality. Lighting conditions are not a concern as the lens will provide uniform picture quality and resolving power day or night. Clip picture quality remains excellent as high pixel count is maintained, helpful for recognising persons. 3. Aperture mechanism supporting P-Iris Stepping motor enables precise aperture control. Depending on the application, aperture range can be controlled to a desired position to optimise the image quality. 4. Compact body, with overall length of just 64.25 mm Uses new iris mechanisms to maintain compact form with high picture quality. Tamron’s years of technical experience have achieved a form that is smaller but maintains super-wide-angle support for high pixel counts, and high performance.Add to Compare

Tamron Co., Ltd., specialised manufacturer of optics and one of the leading companies in the security/surveillance equipment industry announces development of a compact zoom lens for integration with camera modules, Model: DF024NL, supporting 3 mega-pixel resolution in near-IR for security/surveillance use. Development Concept Demand for cameras in fully integrated forms such as mini-dome and bullet-type cameras is on the rise in the security/surveillance market due to ease of installation and well-refined cosmetic design. While cameras require performance exceeding the HD/Full HD resolution, the constraint on the geometric size and compactness are mandated, especially for lenses for mini-dome cameras. Tamron has begun selling Model DF010NL "2-Mega-Pixel/Full HD/Ultra-Small 3X Zoom Lens" (1/3" 3-9mm F/1.2) since 2012. The lens, a compact 3X zoom one of the smallest in the industry and fitting nicely within 3" domes, has been extensively adopted by many camera manufacturers, setting a standard for mini-domes. Mini-dome cameras incorporating a small zoom lens are installed indoors as well as outdoors, and deployed for day/night 24-hour surveillance. When images are captured in black-and-white under very low light conditions in the night-time, the quality tends to drop down to near an SD-level resolution, significantly lower than that in the daytime. In response to the strong market demand for high-quality day/night use, Model DF024NL is developed with the image quality substantially enhanced by use of a new optical design optimally tuned for various lighting conditions around the clock. Main features: 1. Enhanced image quality in the visible light range by means of a new optical design (for 3-mega-pixel cameras) While the existing mini-dome camera market is moving toward higher than 2-mega-pixel/Full HD resolution, Tamron took an early start on a new optical design to deliver 3-mega-pixel resolution over the entire zoom range under visible light, which has achieved unprecedented high-resolution image quality breaking through a conventional standard. 2. Enhancement of near-IR image quality by means of a new optical design (Mega-Pixel) Efficient compensation of optical aberrations in the near-IR bandwidth, and enhancement of resolution and quality for mega-pixel cameras have been achieved by means of a new optical design, delivering clearer black-and-white images when an IR-cut filter is disengaged in the night-time. 3. A compact size that fits within 3" mini-dome camera housings The lens retains one of the smallest sizes in the industry, to fit within 3" mini-dome camera housings, without compromising image quality. 4. A horizontal FOV angle of 93°at the wide-angle end (for 1/3" cameras) Features inherited from DF010NL Use of a mount compatible with DF010NL - Geometrical dimensions of the mount and the boss are compatible with DF010NL. DF024NL is compatible with former products in installation and usage. Incorporation of a stepping motor for focus / zoom drive - Higher-precision focus / zoom adjustment is enabled by use of a lead-screw stepping motor, a feature identical with DF010NL. Continuous employment of the highly-reliable IR-cut filter ON / OFF switching feature that has been validated by DF010NL.Add to Compare

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.
When people think of control rooms, images from James Bond movies or intense action stories come to mind. What they fail to realise is the incredible level of ergonomics, technology, precision and craftsmanship required to create a top-notch command and control room. “These are rooms of complex functionalities, where hundreds of elements must be integrated and function in sync,” says Jim Coleman, National Sales Manager, AFC Industries. Professional teams from several different industries must coordinate every single detail in order to ensure that functionality occurs each and every time. Reconfigurable furniture for control rooms AFC Industries is one company that specialises in equipping control rooms for security and other applications. AFC Industries was established in 1994 as a family-owned business that focuses on the design and construction of ergonomic products. Their height-adjustable units guarantee the right height for standing desks as well as traditional sitting levels. The company produces an array of Command and Control ergonomic security consoles and mounting solutions. Modular racking systems facilitate efficient storage of electronic and audio-visual equipment. As technology changes, older traditional consoles are no longer a necessity. Many organisations instead are choosing to use lighter, less costly, reconfigurable furniture that allows more flexibility. Command Centres need to be able to reconfigure the space at will. Because most systems are housed in secure data centres, users should be able to quickly move their positions by relocating their workstations, utilising different network connections. Simple control room features, like those addressing lighting or operator comfort, can make the difference in a correct or incorrect decision during a crisis Emergency operations centres A positive trend driving the market for control rooms is an increase in emergency operations centres (EOCs), says Randy Smith, President of Winsted. “Everybody is concerned about what happens in an emergency,” says Smith, and the centres are popping up as a tool for emergency preparedness. It’s another environment where sit-stand work stations are the rule. Winsted’s product lines include stock modular and customised elements in good-better-best categories – from basic to lots of “bells and whistles;” jobs can be configured from modular elements or customised as needed. Customised control rooms for seamless operation There is a lot at stake in control room design: Lives can depend on how effectively a control room functions in an emergency. Control rooms should seamlessly accommodate both everyday occurrences and crisis situations, says Matko Papic, Chief Technology Officer of Evans Consoles. Better-operating control rooms can increase efficiency and reduce and/or mitigate risk. Simple control room features, like those addressing lighting or operator comfort, can make the difference in a correct or incorrect decision during a crisis. Addressing operator comfort can reduce the possibility of workers’ compensation claims. End users are seeing multiple benefits of creating a better operating environment, better sightlines, more comfort and attention to ergonomics. As a fully integrated control room solutions provider, Evans Consoles approaches the needs of a control room environment beginning in the conceptual/operational planning stage. They consider broad issues such as how information will be processed, the interface between technology and operators, and the cognitive and physical interactions of operators – understanding that these factors drive the layout and function of control rooms. After analysing tasks to be performed in the environment, Evans lays out the consoles to meet those needs. Rather than a predesigned solution, each installation is tailored around a specific application. Read part 2 of our Control Rooms series here
Many end-users shell out the cash to acquire the newest high-end devices, plug in, and expect to be wowed A well-developed surveillance system can give a single security guard the power to see what otherwise might take a hundred pairs of eyes to see. But what happens when all the components are all connected and powered up, and the resulting image on the screen is, well, indiscernible, or, at the very least, terribly pixelated? Many end-users shell out the cash to acquire the newest high-end devices, plug in, and expect to be wowed. Often enough, however, what they see on the screen is not what they were expecting – and they wonder what they just paid for. In a good high-definition system, what factors actually create the best image quality? With so many variables involved, from the camera’s lens to the imaging algorithms to the monitor resolution – just to name the obvious ones – how do system integrators achieve the best on-screen images? The lens The first component to handle light from an object, this may be the one most taken for granted in cameras of any sort. (Just try scratching or cracking one and you’ll agree.) In the days of analogue cameras, it seemed that any old lens would do just fine. However, as the technology inside cameras evolved and more powerful sensors (more pixels) became available, engineers and programmers demanded more from lenses. Moreover, intelligent video content analyses would be impossible without high-accuracy lenses.In what way do lenses impact the image quality? The key factor here is light transmission. The quality of light passing through the lens itself will forever be critical to the quality of image reproduced. A lens made using ultra-precision molding aspherical technology achieves more accurate colour, better light, and clearer images. Multilayer broadband anti-reflection coating further maximises a lens's light transmission while minimising the residual reflection of light on the surface of each optical lens. Variables involved include the camera’s lens, the imaging algorithms and the monitor resolution When it comes to fabricating a megapixel lens that hits the mark, the materials used and the processes by which lenses are produced are the two most critical criteria. The materials most often used to create lenses are glass and specialised plastics. An HD lens made of ultra-low-dispersion optical glass – which, by using dispersion characteristics that are different from those of conventional optical glass – will deliver better HD performance. Machine-automated lens production using specialised plastics results in high output for camera producers, and the lenses produced are more uniform in design and quality. For an HD vari-focal lens, its image quality depends largely on the precision of the cam. The cam rotates to drive the zoom and focus lens groups forward and backward for a smooth continuity of focal length and adjustment of the focal point. A lack of precision with the cam inevitably causes an offset or tilt of the lens' optical axis during zooming and focusing, leading to a serious loss of image quality. Lens production is a delicate balancing act. The slightest errors or imperfections will be very noticeable when tested Lens production is a delicate balancing act. The slightest errors or imperfections will be very noticeable when tested. The features of a lens that affect image resolution, clarity, and contrast must be perfect. Achieving uniformity of image resolution at the centre and the edges of a lens requires high-precision machinery. And once a lens has been properly crafted, the assembly of the camera, the lens housing materials, and the alignment of the optical axis demand utmost accuracy. To put it mildly, quality control must be rigorous. Image signal processing As light passes through the lens, the sensor captures it and converts it to data. Raw RGB data is transmitted by the camera sensor and undergoes Image Signal Processing (ISP) such as noise reduction, white balance, WDR, curve correction and colour correction, etc. The data is then transformed to true colours for each pixel point, for people to see images that look “normal” to the human eye. It is the Image Signal Processing that defines the final image quality on the screen. Collecting data in different conditions is vital, for instance, outdoor data should be analysed with natural light on days with sun, overcast, rain, and fog, at dawn, at dusk, and so on. Similarly, when using cameras equipped with infrared sensors, testing the IR light signals in various conditions is necessary as well. Actual image performance depends upon variables such as low light illumination, signal to noise ratio, dynamic range of light, and more. ISP algorithms aim at increasing the signal data and decreasing noise. Cameras with Wide Dynamic Range (WDR) will yield improved video imaging with both background and foreground objects in high contrast or high-backlight environments, maximising the amount of detail in brighter and darker areas in one field-of-view. In scenes with low contrast and low light, the sensors deliver digital image signals and at the same time send some amount of digital noise that directly hinders image clarity. Three-dimensional digital noise reduction (3D DNR) removes unwanted artifacts from an image, reducing graininess. Where cloudy weather poses a challenge, auto-defogging technology helps to identify the density of fog or rain with gray-white colour ratio analysis, and imbues images with true colour reproduction. Ramping up the megapixels and frame rates yields great video, but also results in more bandwidth used and more storage occupied Matching megapixels to image quality When the factors mentioned above line up well, correlating cameras and monitors creates the best viewing experience. When a high definition camera is in place, a monitor with a high resolution will display images much more clearly. But if the monitor’s resolution is low, it will not deliver the high-quality images expected – or possible – from that HD camera. For an 8 MP camera, for instance, users do best to apply monitors with 4K × 2K resolution. Though common sense, this deserves to be mentioned because users might decide to upgrade their systems with 4K monitors, but with perhaps 1.3 MP cameras installed. In such a scenario, there’s no guarantee the on-screen image quality will automatically improve. Managing data and bandwidth In terms of a complete, high definition surveillance system, when the right factors come together and the calibrations are set, image quality – even in a standard HD 1080p setup – can be extremely good. The final piece of the puzzle is managing the data. Ramping up the megapixels and frame rates yields great video, but also results in more bandwidth used and more storage occupied. Squeezing bandwidth threatens image quality and clarity, but keeping ample room for signal transmission and storage will eventually increase the overall cost for customers. Is it possible for integrators to optimise their customer’s system and, at the same time, stay within budget constraints? Luckily, it can be done. Squeezing bandwidth threatens image quality and clarity, but keeping ample room for signal transmission and storage increases the overall cost for customers To do this, a more efficient video encoding solution would allow an improvement in compression efficiency of 40–50% over H.264. Improvements to algorithms that are adaptive to a particular scene give users control over bitrate. Another option would be to start recording video only when an event triggers an alarm, since most security guards are primarily concerned with moving objects rather than a scene’s generally stagnant background. This intelligently helps optimise bandwidth and storage consumption. Another method is to use a single panoramic or fisheye camera in place of several HD cameras for coverage – the reduced number of security devices will reduce bandwidth demands and the rate of storage consumption as well. Getting the best image quality Now let’s put this all together. Naturally, integrators and users will refer to their product specs to understand features and functions, fine-tuning each component for best results. Also, as suggested above, users should select an HD camera comprehensively in terms of lens performance, pixels, image quality, and overall system compatibility and performance. Next, matching the backend device and management platform should be carefully considered in a complete security system. Installing equipment that has been engineered for a given scene is a must, along with strategising how to get the most coverage out of the lowest number of cameras. Finally, product quality, warranty, price, and on-going customer service are all important factors that customers should take into account as well.
