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.

How Atlanta’s new Mercedes-Benz Stadium sets the standard for protection against vehicle attacks
How Atlanta’s new Mercedes-Benz Stadium sets the standard for protection against vehicle attacks

Atlanta’s new $1.5 billion stadium, home to the NFL Atlanta Falcons football team and MLS Atlanta United football 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 customised 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 unauthorised 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-metre 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 authorised people through.

Surge protection for security installations: 2017 saw increased investment
Surge protection for security installations: 2017 saw increased investment

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.

Videotec installs MPXHD PTZ cameras for Perusahaan Gas Negara in Indonesia

Perusahaan Gas Negara (PGN) is a company in Indonesia for the transportation and distribution of natural gas. The total length of distribution pipelines of this company is 3,187 km, serving around 84 million customers. As the owner and operator of four transmission pipelines, PGN is responsible for guaranteeing security along the entire chain of conservation and distribution of gas and for delivering products and services in accordance with the needs of consumers. Securing gas supply lines During the transport phase, the gas is pushed through the pipelines at very high pressure. When it reaches the end-users, however, its delivery pressure must be adjusted so that it falls within an acceptable range (as detailed in the contractual delivery specifications). This is to prevent consumers from being exposed to the full transport pressure reached within the pipeline. A metre and regulator station is used to regulate the Natural Gas outlet pressure, and reduce it to an acceptable value. To this end, PGN has developed a meter and regulator station (the Master Control Station) that works via remote control, directed from the control room. This project plays an active role in the PGN's commitment to achieving Operational Excellence in process management, with the focus on optimising safety, improving efficiency and on maximising reliability throughout the gas supply chain operations. PTZ cameras and remote monitoring To guarantee reliability and security of the control function, it is necessary to monitor the process using specialised CCTV equipment for hazardous zones. 10 PTZ units from the MPXHD series have been chosen for the realisation of this surveillance system, because of their reliability in providing perfect video footage and their compliance with the security standards for operation in hazardous areas. The PTZ units are used to directly monitor the metreing and regulating operations remotely from the master control room.

Videotec installs explosion-proof PTZ IP cameras at an industrial complex in Mexico

When overseeing the installation of video surveillance in a refinery, it is necessary to understand that there are a number of complex issues that must be resolved. The infrastructure is, generally, very large and presents a series of extremely dangerous environments and processes that must be closely monitored in order to ensure that the numerous manufacturing operations taking place are carried out safely. Monitor large complex One of the customers in Mexico has asked for a system that enables them to monitor these complex operations in real time, so that precautionary action can be taken, if necessary. The system has to show the work that PEMEX staff and all suppliers within the processes area are undertaking in order to avoid risky situations and ensure that all jobs are performed in accordance with safety standards. In addition, the system needs to be able to show various parts of infrastructure, such as instruments, valves, pipes, etc. and detect any malfunctioning production equipment. In some places, production processes must be monitored as they occur in zones made hazardous by the presence of flammable substances. The customer’s top priority is being certain that the installed cameras themselves are not a possible ignition source for flammable products in the surrounding areas. Explosion-proof PTZ IP cameras The integrator REX ENTERPRISE S.A. de C.V. carried out two projects with these characteristics in Mexico: one in Coatzacoalcos, Veracruz and the other in Poza Rica, Veracruz. In Poza Rica, Milestone software manages the system’s 51 devices, including IP cameras for internal monitoring, analogue cameras from a previous system and 22 explosion-proof PTZ IP cameras. Milestone has been chosen due to its ability to integrate a number of alarm systems, analytic systems, etc. in the future, as it wasn’t possible to fund and use the complete system at the time of installation. ONVIF protocol Videotec's explosion-proof PTZ cameras were selected for their unlimited lifespan, with three-year warranty, their corrosion-resistant construction and their conformation with all the applicable standards for explosion-proof devices. The integration of Videotec products and Milestone is guaranteed by the ONVIF protocol. ONVIF is a worldwide industry standard that offers standardised interfaces and promotes effective interoperability of physical safety products.
