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.
Atlanta’s new $1.5 billion stadium, home to the NFL Atlanta Falcons football team and MLS Atlanta United soccer club and site of the recent NCAA national college football championship, is protecting fans, personnel and athletes from terrorists and errant drivers from using vehicles as weapons. While the threat of terrorists planning to attack soft targets, such as stadiums increases, stadium security professionals, such as those at the new Mercedes-Benz Stadium, must look for the weak points throughout their facilities to determine where fanatics are most likely assailing. Taking their cue from hard target attacks, they and other stadium management understand that the use of vehicles, either to carry the people that will carry out the attack or act as the bomb itself, is a very real threat. New System, Safer Pedestrians Installed by Tusco, using Delta Scientific perimeter protection products, the new access system includes four DSC501 barriers, five DSC720 bollards, 39 DSC2000 barriers and 59 DSC680 fixed bollards. “We are very experienced with installing Delta equipment,” relates Brent Martina, President of Tusco. “Mercedes-Benz Stadium was very particular about their security needs and protocols and requested a customized sequence of operations for their security equipment. While the threat of terrorists planning to attack soft targets increases, stadium security professionals must look for the weak points throughout their facilities “Delta Scientific’s products and experienced engineers made them the obvious choice in meeting both the high quality and technical standards required to integrate with the stadium’s sophisticated security system. It was crucial to have a reliable team in place as we received a very compressed schedule to get everything complete by the first football game and, therefore, had no room for errors.” Because of long, straight approaches to some access points, stadiums oftentimes need to deploy high performance barriers. DSC501 barriers were used at main entrances where players and VIPs, among others, enter with their cars. Preventing Attacks Before They Happen The DSC501 is the only K54-certified retractable vehicle barricade in the world. Set in a foundation only 18 inches deep, it will survive and operate after a 5.4-million-foot pound impact. That’s equivalent to a 65,000-pound truck hitting it at 50 mph. Stopping the truck or car dead in its tracks, the DSC501 protects against a “second hit” risk from a second vehicle. The stadium preferred installing these barricades in a more industrial look, wanting them to be “seen.” Five retractable DSC720 bollards were used at the pedestrian entry areas. This is Delta’s highest crash rated bollard, stopping a 15,000-pound vehicle at 50 mph. The bollard will stop and destroy much larger vehicles than those tested at very high velocities. The DSC720 is 35 inches tall and 15 inches wide. At Mercedes-Benz Stadium, the bollards feature brushed stainless-steel sleeves. Oftentimes, the ground below the access points are filled with cables, wires, pipes and other infrastructure products. As a result, typical, below ground installed traffic bollards, barriers and barricades cannot be used because these infrastructure products are too close to the surface. The solution is to use surface-mounted and shallow foundation barricades and barriers. This isn’t the only stadium using Delta equipment to protect staff and attendees from vehicle harm - Levi’s Stadium in San Francisco is a well-known user Delivery Entrances Are Weaknesses At the same time, for some reason, delivery entrances never seem to be as secured as the main entrances to the stadium. With delivery vehicles coming and going, delivery entrances need a solution that lets delivery vehicles enter and exit but stop unauthorized vehicles from entering at all. At the loading docks, 39 of Delta’s fastest, smallest and shallowest foundation barricades were implemented. Chosen especially for high speed applications and ease of installation, the cost effective DSC2000 barrier is K12 crash-certified with no penetration, meaning it will stop a 15,000-pound vehicle traveling 50 mph dead in its tracks. The ten-inch shallow foundation also reduces installation complexity, time, materials and corresponding costs. Lastly, 50 DSC680 shallow foundation fixed bollards with stainless steel sleeves protect pedestrian areas. They secure any unprotected locations where vehicle bombers and errant drivers have no obstacles. Versus cement barriers such as posts and pots, many organisations prefer fixed-post bollards for several reasons. Terrorists typically don't go where they see barricades, so placing them wherever possible attacks can happen reduces security risks dramatically That’s because, when hit, cement posts and pots can explode, literally spreading shrapnel throughout the crowd, potentially creating numerous injuries. Shallow foundation bollards can be installed within sidewalks or on top of concrete deck truss bridges as well as conform to the inclines and turns of a locale. They also meet the 1-meter clearance regulations mandated by the Americans with Disabilities Act (ADA). The fixed bollard, which does not go up and down, provides a significant blocking device solution that continues to challenge security directors faced with threats such as stopping a vehicle from ploughing into the stadium’s inner perimeter. They let a facility manager meet a long-standing challenge - how to easily install bollards on shallow substrates, including those that are not level or have turns. No longer do locations, such as curves on hills, the upper levels of parking structures and other unprotected locales have to rely on unsightly ‘make-do’ solutions to stop car bombers or wayward drivers. One Of The World's Most Secure “Delayed by roof issues, the Mercedes-Benz Stadium challenged us with a condensed schedule to provide one of the world’s most secure vehicle access systems,” avows Martina. “I’m proud to say that our team completed the work on time and walked away from the project with another pleased client.” This isn’t the only stadium using Delta equipment to protect staff and attendees from vehicle harm. Among many, Penn State and Purdue as well as Levi’s Stadium in San Francisco (49ers) are well-known users. Unfortunately, most procurement offices won't allow vendors to announce their purchases. This is too bad since terrorists typically won't go where they know barricades are deployed, reducing security risks dramatically. Leading universities, including six of the Associated Press (AP) top-10 rated 2018 pre-season football schools, also stayed one step ahead of terrorists and errant drivers this year on their campuses by identifying vulnerable areas and securing them within minutes with Delta MP5000 temporary, portable barriers. These mobile deployable vehicle crash barriers carry a K8 rating (M40 ASTM rating), stopping 7.5-ton vehicles traveling 40 mph. Terrorists typically don't go where they see barricades, so placing them wherever possible attacks can happen reduces security risks dramatically. Today, there is little excuse for a major stadium to suffer an attack which uses a vehicle to break through the perimeter. Whatever the weakness a terrorist thinks can be exploited, there is a type of bollard, barricade or barrier to stop him, yet let authorized people through.
In 2017, DITEK saw how power surges from the many natural disasters that took place damaged many businesses. In a natural disaster, or even everyday business operations, a facility’s entire investment in security, life safety and surveillance systems technology can be disabled or rendered useless in a few seconds. Surge protection solutions can mitigate those risks and protect security investments. Proactive Approach To Risk Mitigation Throughout 2017, we also witnessed a change in how enterprises view surge protection, which included how investments are being made in surge protection to protect valuable security, life safety and surveillance systems, while also reducing downtime, manpower costs, liability vulnerabilities, and possibly compliance issues that can force businesses to actually cease operations. Effective security management is about mitigating risks. But risks cannot be mitigated without a proactive approach. Enterprises and integrators, who take the time to assess risk and to develop a strategy to incorporate effective detection, deter and response criteria to protect physical assets will be successful in 2018. 2018 And Beyond That strategy includes designing surge protection into new security systems, while also adding surge protection to existing systems. Enterprises and security integrators who implement a surge protection strategy during security planning processes – or after – will be exercising prevention and mitigation, and they will be successful in 2018 and beyond. Surge protection devices have an untapped potential for enterprise surveillance and security systems In 2017, Ditek continued to offer security end users a solid surge protection solution. We also successfully educated system integrators, who are seeking value-added products or services to incorporate into their portfolios, on the importance of surge protection devices. Educating Security Integrators We believe that surge protection devices have an untapped potential for enterprise video surveillance and security systems, because they can and do meet safety and security challenges that have been rarely identified in the past. We are looking forward to 2018, when we will continue to develop new surge protection products – including a new product engineered to protect up to twelve individual fuel dispensers, which is critical to the financial operation of convenience stores. We will also continue to educate security integrators about the importance of including surge protection in the design/build RFP, to not only secure an enterprise’s valuable security equipment, but also to help integrators to differentiate their capabilities and knowledge from the competition.
The COVID-19 global pandemic continues, and more and more companies are looking for ways to continue (or resume) operations while minimizing the coronavirus’s negative impact on their workforce, or potentially contributing to disease spread among the wider population. Thermal cameras have been proposed as a solution to screen individuals for elevated body temperature since the beginning of the pandemic. However, the technology has its detractors, and there are regulatory questions. We asked this week’s Expert Panel Roundtable: How can thermal cameras be used effectively for fever detection to screen for infectious diseases?
Dahua Technology, a video-centric, provider of smart IoT solutions, offers a wealth of low-light technology for surveillance in dark or nighttime environments. The latest addition to their wide-ranging line of security cameras for the Dahua USA market is White-light LED Night Color technology. Dahua Technology USA boasts several different low-light camera models to meet a variety of needs in environments with very low ambient light. Each camera incorporates an ultra-Starlight image sensor, which has a set of optical features to balance light throughout the scene and improve the clarity of the image. Low-light cameras also utilize Smart Image Signal Processing (ISP). Extracting useful information “Smart ISP converts an image into digital form while performing operations that enhance the image and extract useful information. It lets the camera identify and correct imperfections caused by the lens, color filter, or sensor,” explained Jennifer Hackenburg, senior product marketing manager at Dahua Technology USA. Dahua’s flagship low-light standard, Starlight technology, employs large apertures (maximum f/1.6), in addition to the sensors and Smart ISP described above, to balance light throughout the scene. Together, these technologies let Starlight cameras produce richly colored, identification-level images without distortion in illumination of 0.004 to 0.009 lux. Starlight cameras have infrared (IR) cut filters that switch to black and white mode when the camera senses that insufficient light is available to reproduce good color images. When night mode is triggered, the filter disengages, allowing IR as well as visible illumination to reach the image sensor. Achromatic large aperture lens Night Color does not require a True Day Night IR cut filter; instead it uses a high-performance sensor and ISP The latest advancement in light sensitivity is Night Color technology. Night Color cameras use high-performance image sensors that generate exceptional color images long after an IR camera would have converted to a black and white image. Night Color does not require a True Day Night IR cut filter; instead it uses a high-performance sensor and ISP, as well as an achromatic large aperture lens, to produce crisp, clear images. This light-sensitive technology allows the camera to capture more available light, creating full-color images with high detail and contrast. Night Color requires at least 1 lux of ambient or artificial light. When a visual deterrent to crime is imperative, white-light LEDs (Light Emitting Diodes), are built into Dahua’s new 4MP ePoE Night Color Network Dome Camera (N45EJ62). Real-Time perimeter protection Smart illumination, where the camera automatically activates the LEDs at low lux levels, adjusts exposure time and LED intensity to avoid overexposing the image. The camera performs Dahua’s Analytics+ functions at the edge for complex, real-time perimeter protection surveillance, Smart Motion Detection, and face detection. Enhanced Power over Ethernet (ePoE) extends transmission distances up to eight times over CAT5/CAT6 cables and converts existing, coax‐based analog systems into IP systems. “Our broad portfolio of low-light cameras gives installers and end-users a variety of options to choose from, based on their individual needs,” commented Hackenburg. “Whether low lux capabilities are most important, or you need advanced technology that enables full color images in near-complete darkness, Dahua helps security operators see more.”
Dahua Technology, a globally renowned video-centric provider of smart IoT solutions, has announced the launch of SafetyTemp (DHI-ASI7213X-T1), a thermal temperature monitoring station. This easy-to-deploy solution quickly measures skin temperature without the need for personal contact and provides an accurate temperature reading to help businesses and schools assess employees, customers, students and other visitors for elevated body temperature. SafetyTemp thermal temperature monitoring station Developed in response to the COVID-19 pandemic, the SafetyTemp system features a simple, portable setup that consists of a seven-inch screen and a camera with dual, 2MP, CMOS sensors. Different installation options, such as floor and desktop mounts, make SafetyTemp a versatile solution for shops, restaurants, schools, and factories that need an efficient method to assess temperatures of employees, customers, students and other visitors. This contact-free solution for monitoring temperatures uses thermal imaging technology to reduce the risk of viral transmission and deliver peace of mind. Thermal imaging technology Thermal imaging technology allows for swift, accurate, temperature readings without personal contact" “Thermal imaging technology allows for swift, accurate, temperature readings without personal contact,” remarked Damon Chou, Product Solutions Manager at Dahua Technology USA, adding “SafetyTemp offers this technology in a compact, user-friendly station that helps businesses reopen more safely and schools better monitor their student populations during the pandemic.” A subject must simply look at the camera for the system to get a temperature reading. The system will almost instantly (within 0.2 seconds) indicate whether a temperature is elevated above an operator-defined threshold. A visual display on the screen, as well as an audio alert, will let the operator know immediately when an elevated temperature has been detected. Integrated with WDR camera An additional setting will alert the operator if the system detects that a subject is not wearing a mask. The Wide Dynamic Range (WDR) camera is well-suited for high-contrast lighting environments, such as building entrances, and its infrared sensor can detect temperatures within a ±0.9°F (±0.5°C) range of accuracy from a distance of one to six feet (0.3 to 1.8 meters). “SafetyTemp’s ability to quickly scan people as they pass through an area reduces long lines and wait times for business owners and administrators who want to safeguard the health of their employees, customers or students,” Chou continued, adding “Dahua aims to support the reopening of schools and commerce with this simple yet powerful solution.”
