Razberi Monitor is a software platform that provides a top-down view of the physical security network and ecosystem without IT resources. Purpose-built for security professionals, it monitors and manages all the system components for cybersecurity and system health and can be deployed from the cloud or on-premise. It provides secure visibility into the availability, performance, and cyber posture of servers, storage, cameras, and other networked security devices. It also predicts and prevents problems while providing a centralized location for IT departments to view video data. What is Monitor’s key USP? A vital benefit of Monitor is that it protects against the multiple commonly cited cyberattack vulnerabilities. These include weak passwords, the failure to update software or firmware, the lack of best practices for routine maintenance, and not aligning with network IT policy. The benefit of having Monitor ensures shorter response times to cybersecurity events along with real-time alerts and logs to proactively notify users of active threats. It can detect cyber posture and problems with servers, cameras, and other IoT devices in real-time. You can track security devices by location and get deep visibility into configurations, operating systems, and firmware status. This means that without IT resources, you can still know what devices need updates and patches. Why choose Monitor? Monitor can be offered to enterprises as a managed service with a monthly subscription. This means no significant upfront costs and the ability to free up cash flow. The Monitor software will optimize and secures networks, reducing costs, time, and manpower required to install and manage an enterprise network. Users can create custom views and alerts by location, device, and problem type. They can use these reports to demonstrate system performance and compliance, share access to these reports with their service provider for proactive support, and reduce service calls. Monitor in Action Monitor enables proactive maintenance by offering problem resolutions before they become more significant issues. It does this by ensuring that the system is working as expected through continuous checks on the system’s health and cybersecurity and prevents service outages with early warning indicators. Identifying issues before they fail and become an outage is key to system availability and, moreover, is a considerable OPEX cost saving. For example, if there is an incident in a supermarket and a client wanted to review their cameras, only to realize that they had stopped recording some weeks before. With Monitor, if the client’s cameras are failing or are in any way beginning to compromise, this would be immediately detected by Monitor and flagged in advance of it failing. Thus, when an incident does occur that requires video verification, clients can be assured that the video data will be available to review the incident.

Hikvision, an IoT solution provider with video as its core competency, announced its latest traffic product offering - the All-Rounder ITS camera - designed to improve road safety and optimize traffic flow. As the name implies, the camera encompasses different skills and abilities, boasting speed detection, traffic violation detection, automated plate recognition, and vehicle attribute analysis in one housing. “Hikvision is always pushing the boundaries of video technologies. Beyond the visual range that is perceived by video cameras, the abilities to understand other kinds of “senses” would allow even more precise monitoring and reporting of events or accidents,” says Frank Zhang, President of International Product and Solution Center at Hikvision. “This is multi-dimensional perception, a trend that we think will affect the security industry in the future.” Optimising traffic flowThe new ITS camera is designed and developed with this multi-dimensional concept in mind. It is Hikvision’s first camera to integrate three otherwise separate modules in one unit with no compromise on performance, making the camera neat and flexible to be deployed for demanding environments, all in an easy and cost-effective manner. The product provides an HD camera, speed radar, and light array inside one housing. Specifically, it works with a multi-tracking radar that continuously monitors up to two or three traffic lanes - depending on the camera model, and identifies the speed and position of objects in the monitored area at a speed of up to 300 km/h. If a vehicle violates the speed limit, the embedded radar triggers the connected camera and a picture is taken of the vehicle and its license plate. Conventional ANPR systemsIn the event of infringements of traffic rules such as wrong-way driving, improper lane usage, or even failure to use a seat belt, the camera will capture images of the corresponding vehicle, recognize its license plate and relevant information including vehicle type, color, brand, and direction of movement, which can be addressed to the authorities in real-time or stored on board. Incident detection helps to improve overall driving standards, which ultimately reduces the number of accidents, improves road safety and further evens traffic flow. Employed with Deep Learning algorithms, the camera is able to recognize a much higher number of license plates and with higher efficiency than conventional ANPR systems. Its GMOS sensor further ensures brighter and smoother images to be reproduced in challenging lighting conditions, especially in low-light environments. The camera’s embedded supplemental light features a 16-bead light array, offering an IR range of up to 40 metres at night. Seamless onsite configurationAs all of these functionalities are integrated, the single product itself outperforms conventional ITS products with space-saving and less cabling for easier installation.

The bright and dark area can get clear video even in high brightness environment or with backlight shadow. Super AdaptEmbedded with intelligent algorithm, for changing external environment, camera can automatically adjust parameters to present the optimal image, and it solves the trouble of configuration. Advanced 3D NR3D NR is noise reduction technology that detects and eliminates random noises by comparing two sequential frames. Dahua's advanced 3D NR technology allows remarkable noise reduction with little impact to sharpness, especially under limited lighting condition. Besides, the advanced 3D NR effectively decreases the band width and saves the storage space. Smart IlluminationThe camera is designed with IR illumination for best lowlight performance. Smart IR is a technology to ensure brightness uniformity in B/W image under low illumination. Dahua's unique Smart IR adjusts to the intensity of camera's infrared LEDs to compensate for the distance of an object, and prevents IR LEDs from overexposing images as the object comes closer to the camera. Protection (IP67, IK10,wide voltage)IP67: The camera passes a series of strict test on dust and soak. It has dust-proof function, and the enclosure can works normal after soaking in 1 m deep water for 30 mins.IK10: The enclosure can stand the punch more than 5 times from a 5 kg hammer falling from a height of 40 cm (Impact energy is 20J).Wide voltage: The camera allows ±30% (for some power supplies) input voltage tolerance (wide voltage range), and it is widely applied to outdoor environment with instable voltage.
Hikvision, an IoT solution provider with video as its core competency, announced the launch of HeatPro, a new thermal series of cameras designed to provide affordable all-weather deterrent and alerts. It is especially useful in perimeter protection and fire prevention applications. The HeatPro Series Cameras feature deep-learning thermal video analytics for perimeter protection, and object temperature measurement and fire detection with real-time alarms. Features like accurate human/vehicle classification, visual and auditory alarms for perimeter protection, and speedy temperature exception alarms for fire prevention make them ideal for SMB (small and midsize business) applications. Perimeter defense with AIWhen securing a perimeter, higher accuracy and a low false alarm rate can help reduce operation costs. The HeatPro Series achieves this by developing powerful video analytics based on Deep Learning algorithms, radically reducing false alarms. The cameras focus on short-range perimeter protection (0-50meters), where they deliver target detection and classification. The use of AI means that the cameras can distinguish between a person and a vehicle. This comes in especially useful when the two targets are close together. Traditionally, they can only be recognized as one ‘target’, but intelligent algorithms mean that they can be detected separately, increasing accuracy. Thermal cameras are also able to easily locate potential threats in zero visibility conditions, where a conventional camera could not. They do this by detecting the latent radiation emissivity of an object, so not relying on visible light. This means they can operate in all-weather conditions and the darkest night. They also don’t emit light, which means their presence is not obvious, making them useful in scenarios where they need to be hidden. The HeatPro Series is also designed to be efficiently and quickly installed, with a simple, three-step deployment, bringing setup time down to 30 seconds. Traditionally thermal cameras require specialist engineers to configure and double check, takes both extra time and energy. HeatPro cameras have been designed with installation time and effort in mind – they are simpler to install and so installers can spend more time correctly configuring for optimum operations, and the lowest false alarm rate possible. Temperature measurement for fire preventionThe HeatPro Series is also equipped with the ability to measure temperature. This process is very useful in a scenario where overheating could lead to fires. The camera can provide non-contact temperature measurement for fast and visible detection. This means that action can be taken earlier, potentially preventing a fire from the very beginning. The camera can trigger a fire alarm faster than a smoke sensor. The temperature measurement function can also be used to help check any potential overheating issue and troubleshoot problems. The series contains a number of different models and options, with bullet and turret forms, and Bi-spectrum or single lenses. The cameras can be built into a number of solutions, for instance seamlessly working with NVRs, AX PRO alarm systems, and even Hik-Connect for real-time mobile alerts by phone. They can be used in various scenarios – not least: residential buildings, offices, construction sites, car parks, retail outlets and warehouses. “Dedicated to bringing professional protection solutions to the mass market, these cameras provide perimeter protection with unparalleled accuracy, and fire detection with superlative sensitivity”, says Stefan Li, Director of Thermal Products at Hikvision. “Hikvision HeatPro Series provides professional protection made simple.”

Security camera lens products updated recently
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.
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 organizations instead are choosing to use lighter, less costly, reconfigurable furniture that allows more flexibility. Command Centers need to be able to reconfigure the space at will. Because most systems are housed in secure data centers, 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 Centers A positive trend driving the market for control rooms is an increase in emergency operations centers (EOCs), says Randy Smith, President of Winsted. “Everybody is concerned about what happens in an emergency,” says Smith, and the centers 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 customized elements in good-better-best categories – from basic to lots of “bells and whistles;” jobs can be configured from modular elements or customized as needed. Customized 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 analyzing 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 analog 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 color, better light, and clearer images. Multilayer broadband anti-reflection coating further maximises a lens's light transmission while minimizing 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 specialized 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 specialized 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 center 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 color correction, etc. The data is then transformed to true colors 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 analyzed 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 color ratio analysis, and imbues images with true color 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 optimize 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 optimize 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.
