HD over Coax provides cost-effective video surveillance upgrade
HD over Coax provides cost-effective video surveillance upgrade

According to IHS Market, it is estimated that there are over 60 million security cameras in the United States, and other reports say these cameras capture more than four billion hours of footage per week. Over the last decade, IP camera technology has dominated the conversation as it has provided users with a broad offering of enhanced image quality and features. With a large percentage of existing security systems relying on 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.

Saving lives with effective security control centre design
Saving lives with effective security control centre design

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

HD surveillance: Secrets to producing the best possible image quality
HD surveillance: Secrets to producing the best possible image quality

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.

Hanwha Techwin expands Wisenet X PTZ PLUS range of cameras equipped with AI object tracking
Hanwha Techwin expands Wisenet X PTZ PLUS range of cameras equipped with AI object tracking

The six new cameras added to the Wisenet X PTZ PLUS range have been developed by Hanwha Techwin to enable users to capture evidence grade images of activity occurring in large open area applications. The ability of the new 2MP, 6MP and 4K Wisenet X PTZ PLUS cameras to operate effectively in environments such as airports, car parks, industrial estates, stadia and city centres, is enhanced by a long list of technically advanced features, which include AI-based object tracking, precise PTZ control and improved pre-set accuracy. The cameras, which have a lightweight, compact form factor, are also able to capture high-quality images of objects up to a distance of 200 metres regardless of the lighting conditions, with the help of adaptive IR technology which adjusts the angle of the camera’s IR LEDs to match the level of zoom. AI auto-tracking Operators can programme a camera to lock onto and auto-track a specific object with the help of deep learning video analytics An AI auto-tracking feature allows control room operators to efficiently monitor the movement of objects while remaining hands-free to control other cameras. With a right-click of a mouse, operators can programme a camera to lock onto and auto-track a specific object. It does so with the help of deep learning video analytics which detects and classifies people and vehicles. The video analytics is supported by AI algorithms unique to Hanwha Techwin. Alternatively, operators can take advantage of highly accurate manual control PTZ functionality to zoom in to see close up detail of target objects and track their movement. Other key features and functions Pre-set Accuracy: During their life cycle, most PTZ cameras are likely to be expected to ‘pan and tilt’ many thousands of times and it is not unknown for positioning errors to occur. Wisenet PTZ PLUS cameras, which have a pre-set accuracy of ±0.1˚, are able to detect if they are not precisely aimed at the specified field of view and will move within one second to the correct position. Focus Save: Applied to up to 32 pre-defined areas, focus save functionality ensures that regardless of the lighting conditions, a camera is able to rapidly come into focus when it is moved to a new position. Tilt Range: The cameras’ extended tilt range of up to 110⁰ allows any objects positioned above the cameras to be seen. Wisenet7 chipset At the heart of all Wisenet X PTZ PLUS cameras is Wisenet7, Hanwha Techwin’s most powerful chipset to date, which with extreme’ Wide Dynamic Range (WDR) functionality that utilises Local Contrast Enhancement and Scene Analysis technologies, is able to facilitate the capture of ultra-clear images from scenes containing a challenging mix of bright and dark areas. Excellent low light performance is also assured thanks to the utilisation of 3D noise reduction technology which, while minimising motion blur, uses several filters to isolate and remove pixels that are causing noise, while a new noise reduction algorithm improves the edge and colour of objects. Cyber secure Wisenet7 chipset incorporates a list of technologies that significantly enhance the cyber security credentials Complying with UL CAP and Secure by Default standards, the Wisenet7 chipset also incorporates an impressive list of ground-breaking technologies that significantly enhance the cyber security credentials of the Wisenet PTZ PLUS cameras. They also benefit from a Hanwha Techwin proprietary device certificate issuing system which embeds unique certificates into Wisenet products during both the development phase and manufacturing process. This further enhances the camera’s ability to prevent hackers from tampering with its firmware. Installer friendly Compact and approximately 65% lighter than most PTZ domes, the camera-mount installed Wisenet X PTZ PLUS cameras can be quickly and easily deployed, requiring engineers during a first fix to just ‘match 3 points and twist’. This conveniently enables them to tighten screws without having to hold onto the camera. Unlike conventional PTZ cameras which require up to 5 separate cables, the Wisenet X PTZ PLUS cameras only need a single RJ45 cable to operate and this is installed with a flexible bush to ensure the camera is waterproof. The new Wisenet PTZ PLUS cameras are as follows: Wisenet XNP-9250: 4K 25x PTZ camera Wisenet XNP-9250R: 4K 25x IR PTZ camera Wisenet XNP-8250: 6MP 25x PTZ camera Wisenet XNP-8250R: 6MP 25x IR PTZ camera Wisenet XNP-6400: 2MP 40x PTZ camera Wisenet XNP-6400R: 2MP 40x IR PTZ camera Authority comments “Our comprehensive Wisenet camera line-up offers a variety of options for monitoring wide open areas. However, I would encourage consultants, system designers and system integrators to take a close look at our PTZ PLUS range when there is a need to closely monitor and automatically track moving people or vehicles,” said Uri Guterman, Head of Product & Marketing for Hanwha Techwin Europe. “Our design, development and manufacturing teams have combined their expertise to pack these cameras with a long list of practical features and innovative technology which collectively will surely meet, if not exceed, users’ expectations.”

Hanwha adds Wisenet PNM-9022V and Wisenet PNM-9322VQP to their range of multi-directional cameras
Hanwha adds Wisenet PNM-9022V and Wisenet PNM-9322VQP to their range of multi-directional cameras

Two new Wisenet cameras equipped with Hanwha Techwin’s ground-breaking Wisenet7 chipset have reinforced the company’s claim to be the manufacturer of multi-directional cameras.  The 4-channel PNM-9022V utilises alpha blending technology to stitch the overlapping images captured by its four Full HD sensors into a seamless 8.3-megapixel 209° image, thus ensuring an operator never loses sight of a person or vehicle moving across a wide area. Digital PTZ functionality Superseding the highly successful Wisenet PNM-9020V, the PNM-9022V can also be used to capture 180° images, with operators able to take advantage of digital PTZ functionality across two of the camera’s channels. With Wisenet7 SoC, Hanwha Techwin’s most powerful chipset to date, at its heart, the PNM-9022V’s 4 sensors, which come with 2.8mm fixed focal lenses, are able to capture high definition colour images when the lighting level is as low as 0.03 Lux. Wisenet7 also features Hanwha Techwin proprietary ‘extreme’ Wide Dynamic Range (WDR) technology which, performing at up to 120dB, utilises new Local Contrast Enhancement and Scene Analysis technologies to enable the camera to capture ultra-clear images from scenes containing a challenging mix of bright and dark areas. Certificate issuing system Lens Distortion Correction (LDC) technology utilised by the PNM-9022V corrects the distortion created Lens Distortion Correction (LDC) technology utilised by the PNM-9022V corrects the distortion created through the use of wide-angle lenses. This delivers images which more closely resemble what is seen through the human eye. As part of the fast-growing number of new cameras which incorporate the UL CAP certificated Wisenet7 chipset, the National Defence Authorization Act (NDAA) compliant PNM-9022V is packed with an impressive list of technologies to protect it from cyber-attacks. It also benefits from a Hanwha Techwin proprietary device certificate issuing system, which embeds unique certificates into Wisenet7 products during both the development phase and manufacturing process. This further enhances the camera’s ability to prevent hackers from tampering with its firmware. Cable connection purposes 2 Micro SD/SDHC/SDXC slots enable up to 1TB of video or data to be stored at the edge should there be disruption to the network. Video of any incidents, which potentially might have been lost on the recorder side, can therefore be retrieved from the camera when the network connection has been restored. Minimising the time needed to be spent on site, the PNM-9022V has a hinged backplate to provide easy access for cable connection purposes. Installers have to simply install the back plate, clip the camera in place and tighten two screws. Intelligent video analytics Other key features include the following: A suite of built-in Intelligent Video Analytics (IVA), which includes audio detection, defocus detection, directional detection, enter/exit, appear/disappear, motion detection, virtual line and camera tampering detection. Heatmap video analytics which provides business intelligence on customer density and buying behaviour. Support for WiseStream II complementary compression technology, as well as H.265, H.264 and MJPEG compression formats. Bandwidth efficiency is improved by up to 75% compared to current H.264 technology, when WiseStream II is combined with H.265 compression. PoE+ which negates the need to install a power supply and separate cabling for the camera. IP66, IK10 and NEMA4X rated for protection against water, dust and mechanical impact. Cost-effective solution Coinciding with the launch of the PNM-9022V, the PNM-9322VQP with 4 sensors and an integral PTZ camera, is designed to provide a highly cost-effective solution for detecting and tracking objects over wide open areas. The option of exchangeable 2 and 5-megapixel lens modules enables the camera’s sensors to work together to seamlessly capture 360° images of up to 20-megapixel resolution. In addition, the device’s PTZ camera element can be configured to zoom in and track a moving object or move to a user defined preset position when the line crossing detection function of the multi-directional camera detects activity. It is also able to ‘hand-over’ to cameras covering adjacent areas to ensure operators can continue to observe people or vehicles as they move out of its field of view. Providing audio support The NDAA compliant PNM-9322VQP supersedes the highly successful PNM-9320VQP Equipped with the Wisenet7 chipset, the NDAA compliant PNM-9322VQP supersedes the highly successful PNM-9320VQP, with the additional benefit of providing audio support. “These two new models perfectly complement our other existing 2, 3, 4 and 5-channel multi-sensor cameras which collectively enable us to offer customers an affordable multi-directional camera solution for virtually any video surveillance project,” said Uri Guterman, Head of Product & Marketing for Hanwha Techwin Europe. Providing significant savings “All of these cameras will help users achieve a high return on investment (ROI) as they can perform the role of a greater number of standard HD cameras. In doing so, they provide significant savings on camera purchasing costs and with less cable, conduit, mounting hardware and network switches required, installation costs are reduced as well. With only a single IP connection, they also only require one VMS licence.” “The value of these two new cameras being NDAA compliant and UL CAP certificated should also not be underestimated. System integrators will quite often find that both can be a key requirement when they are submitting tenders for projects involving end-users which operate multi-nationally.”

Hanwha Techwin launches Wisenet Public View Monitors with built-in camera
Hanwha Techwin launches Wisenet Public View Monitors with built-in camera

A new range of Wisenet Public View Monitors (PVMs) equipped with a built-in SSL connected 2-megapixel camera have been introduced to help retailers deter fraudsters and shoplifters. Offering a choice of 10”, 27” and 32” monitors, the 3 new PVMs are designed to be located at store entrances, shopping aisles, till points or self-checkout pay points. With an SD/SDHC/SDXC slot that can facilitate up to 512GB of data storage, the PVMs provide store management with the opportunity to display a slide show which can include supplier adverts, own-brand product promotions and special offers. A default blinking recording in progress message is superimposed over the displayed graphics to let would be thieves know they are on camera, with operators having the option to customise the message and configure its size, colour, opaqueness and positioning on the monitor. Face detection Face and motion detection feature can be configured to switch the display to live view to make people aware they are being watched Supported by the Wisenet WAVE and SSM video management platforms as well as Wisenet NVRs, the ONVIF Conformant PVMs can be programmed so that images captured by the cameras are either continuously recorded or when prompted to do so by built-in face or motion detection video analytics. The face and motion detection feature can also be configured to switch the display to live view to make people aware they are being watched, as they will be able to see themselves on the monitor as they enter a store or walk down a shopping aisle. The display reverts to the slide show after a specified number of seconds. The PVMs, which can be integrated with tagging (EAS) systems to record images of people who might be leaving the store with stolen items, also provide support for the AI-Masking, AI-Bio, AI-Face-Detect and AI-Occupancy video analytics applications, developed by Hanwha Techwin’s technology partner, A.I. Tech. Video evidence Regardless of whether they are displaying live images or a slide show, or the monitor has been turned off by someone using a remote control, the PVMs will continuously stream images to a control room where they can be viewed via video management software (VMS), as well as continue to be recorded on an on-site or remotely located NVR. The ultra-low light capabilities of the new PVMs, together with Wide Dynamic Range (WDR) technology performing at up to 150dB, enables the built-in camera to capture clear, sharp images in strongly contrasting light conditions at, for example, store entrances where strong sunlight may be streaming in. Power over Ethernet All three PVMs can be powered by 12V DC, with the Wisenet SMT-1030PV also offering the option to utilise Power over Ethernet (PoE+) if there isn’t an existing power supply close to where the PVM is being installed. A single cable of up to 100m is all that is needed to provide both powers to the SMT-1030PV and for network communications. The three new Wisenet PVMs, which can be mounted by using standard VESA brackets, are as follows: SMT-1030PV: 10” monitor with LED backlight and 1024 x 600 display resolution. SMT-2730PV: 27” monitor with LED backlight, HDMI input and Full HD display. SMT-3230PV: 32” monitor with LED backlight, HDMI input and Full HD display. Loss prevention strategy “With retailers increasingly relying on PVMs to play an important role within their strategic approach to loss prevention, we have designed our new models to make it quick and easy, as well as cost-effective, to deploy them across a large number of stores,” said Uri Guterman, Head of Product & Marketing for Hanwha Techwin Europe. “As the only PVMs available which, for cyber security and data protection purposes, are supplied with a complete built-in SSL connected camera, they eliminate the need for system integrators to install and connect a separate supporting camera, which some other manufacturers’ PVMs require." "By building in an intuitive user interface, we have also made it extremely easy for busy store managers to take full advantage of the PVM’s functionality, including the ability to utilise the monitor for advertisement and signage using the slide show mode.”
