Network Video Technologies' (NVT's) range of award-winning unshielded twisted pair (UTP) CCTV camera video
transmission products, have been employed to provide high-performance CCTV transmission at five aircraft service and maintenance hangers at King Khalid International Airport.

Located 35 kilometers (22 miles) north of Riyadh, Saudi Arabia, as part of a comprehensive airport complex that includes three terminals, a control tower and two parallel runways, the five specially equipped hangers are used to carry out repairs and scheduled maintenance on a variety of international and national airlines' aircraft.

With over 10,000 sq. metres of floor space each, the five service hangers can cater to aircraft as large as the latest Airbus A380, Boeing 747-400, or multiple single-engine light aircraft. Assisting the provision of effective health, safety, fire prevention, and security procedures at the massive complex, an NVT-based CCTV system has been specified and installed by the Modern Buildings Group. Mr Mohammad Amin Almatt of Modern Buildings Group explains: "We planned to use CCTV images from the system for a variety of roles, including security, health and safety and fire/smoke detection, via the use of Video Smoke Detection (VSD) units, so the quality of video we required from the cameras was of great importance. 

"Employing a traditional coax based system at the site would have proven very costly, time consuming to install, and would have meant that an individual fused spur power outlet would have been needed at each of the 25 internal and 10 external camera locations. This would have added significant supplementary costs in equipment and installation time. Additionally, camera locations ranged from 200m to 1Km in end-to-end transmission distance to the on site control room. Employing coax over these distances would have been detrimental to the camera image quality in this mission critical system."

NVT PVD™ is key

Utilising NVT Power, Video & Data (PVD) technology, the Modern Buildings Group engineers were able to provide each camera in the system with low voltage power, transmit fiber-like quality to the control room, and provide camera telemetry - all via a Cat5 UTP network contained within each hanger's structure. From here, a 25 pair Cat3 UTP backbone is then used to transmit images from each hanger, back to the centrally located equipment and control room. 

Protecting the perimeter of each hanger, Pelco Spectra PTZ dome cameras with UTP outputs are situated on the exterior corners of each hanger. Images from these cameras are used to monitor the hanger environment for any possible unauthorized entry, and to ensure health and safety procedures around the hanger are adhered to. 

Within each hanger, Pelco Spectra Mini Dome cameras are mounted in four equally spaced positions along an interior wall. Each Pelco Spectra Mini Dome is equipped with a UTP video output that allows direct connectivity to the UTP cabling network and transmission back to an NVT NV-4PS10- PVD 4-Channel Power Supply Cable Integrator Hub. Each NVT Power Supply Integrator Hub is located at a secure point within each hanger and provides a 1 amp/channel power supply for each of the hanger's four cameras, alongside pass through video and telemetry data - all via each hanger's Cat5/Cat3 UTP network cabling infrastructure. 

Exterior cameras are linked via Cat5 UTP to a centrally located NVT NV-16PS10-PVD 16-Channel Power Supply Cable Integrator Hub, which also provides individual power supply and pass through video and telemetry data to the control room. 

"Powering cameras via the UTP connection was a great advantage," explains Mohammad Amin Almatt. "It ensured that we kept control of all aspects of the installation and did not have to rely on third-party electrical installers to provide fused spurs for each camera point. This also presented a significant installation cost-saving that we were able to pass on to our customer."

 UTP Transmission - Network Backbone and Control Room

Camera signals are transmitted to the on-site control room via a 25-pair Cat3 backbone, where they are received by two NVT NV-1672 16-Channel DigitalEQ™ Active Video Receiver Distribution Amplifier Hubs in the equipment/control room. Employing NVT's latest generation DigitalEQ™ technology, theNV-1672 is a 16-channel active (amplified) hub that allows the transmission of real-time monochrome or color video for distances up to 1,6km (1 mile) using UTP cable - well within specification of camera infrastructure at the airport, the furthest of which is 1Km from the control room. The DigitalEQ™ receiver hub continuously and automatically conditions each video signal, compensating for cable attenuation, wiring polarity, ground loops, and voltage transients, independent of video signal content. This DigitalEQ™ technology provides the best possible image quality right from the moment of connection - all of which were of advantage to the Modern Buildings Group engineers whilst installing and commissioning the system.

Bahrain Airport, the airport will host NVT's CCTV surveillance for improved airport security 
 King Khalid International Airport has been provided with an innovative electronic surveillance solution

Mohammad Amin Almatt explains: "Utilising the NVT NV- 1672 hub with DigitalEQ™ technology meant a smooth, error-free and rapid installation process for our engineers. Via simple cable connectivity, we were able to consult the intuitive LED indicators on the hub's front panel to instantly diagnose both power and video connectivity for each channel. Had we used a traditional coax transmission method or powered each camera locally via a dedicated fused-spur, we would not have enjoyed such simple and instantly accessible connection diagnostics, which could have resulted in an protracted installation period."

In addition to on-site monitoring and recording via the latest control and DVR technology, the high- performance images are also monitored by electronic Video Smoke Detection software. VSD was developed to overcome the difficulties encountered in environments where traditional forms of smoke and flame detection are considered to be ineffective or impractical, such as the aircraft service hangers. False alarms could be frequently created as a by-product of everyday on site processes. To overcome this, the Riyadh system uses VSD technology that analyses live CCTV camera images - using advanced video analytics to detect the unique movement of smoke via the behavior patterns of each pixel in the video image."This is why a consistent quality of image is so important at the hangers," explains Mohammad Amin Almatt. "Using NVT technology we were able to provide both the DVR and VSD devices with conditioned, interference free video.

Thanks to the continuous and automatic conditioning of the video signal via the NVT DigitalEQ™ technology, the image quality remains consistent and unaffected by changing conditions, such as interference levels or changing lighting conditions - critical for these types of video analytic packages. This again removes the need for any further image adjustment and eliminates another potential source of false alarm." 


If the unique graphical signature of smoke is detected within the video image, the VSD system can automatically release fire doors, sound alarms and provide speech evacuation commands through the PA system - all whilst alerting an onsite fire response team that consists of five separate fire stations with specialist fire fighting vehicles. 

"The system's performance is proving a great success," concludes Mohammad Amin Almatt. "We have provided an innovative electronic surveillance solution that fulfills multiple roles within the unique demands of the aircraft service environment. Thanks to our expertise and NVT technology, we were able to deliver a reliable, high-performance and cost effective CCTV solution to our customers at King Khalid International Airport."

Sanitization, Safety And Getting Back To Business
Sanitization, Safety And Getting Back To Business

You are not alone: operators everywhere are asking themselves what are they going to do? How are they going to get back to business, and fast? How are they going to cost-effectively operate with all the new safety requirements that have arisen as a result of COVID? How are they going to ensure it all gets done for the safety of customers and staff? How are they going to protect their brand from the negative exposure of being identified as a property with a reputation for COVID? The economic impact of COVID is expected to hit brick and mortar businesses the worst, as their businesses are dependent on people being physically present. According to a recent report by RBC, it is estimated that 70% of Americans expect to avoid public spaces, 57% of Canadians will be unwilling to attend conferences without a vaccine and 63% of people will prefer to drive vs fly.  This means, that for those of you in the business of travel, conferences, co-working spaces, retail stores, museums, art galleries, restaurants, sports arenas, hotels, cruises, airlines, resorts, theme parks, long-term care, education, etc. in the blink of an eye your approach to on-site safety just changed. To ensure your property is safe and secure, it is no longer just about access control, video surveillance and intruder alarms; it is also about sanitisation To get back to business and operating at full capacity after COVID, operations must find a way to eliminate the fear, uncertainty and doubt in the minds of their customers and employees. The affect of COVID-19 on safety and security To safely get back to business, the Centers of Disease Control and Prevention (CDC) emphasis that all operations need a pandemic response planJust like cybersecurity has had a direct impact on the IT strategy and budget, COVID will have a direct hit on the operations strategy and budget. To ensure your property is safe and secure, it is no longer just about access control, video surveillance and intruder alarms; it is also about sanitization, the lines between the security and maintenance just blurred. From customers, to employees, to government regulators, to management, the focus is now on operations and the sanitization policies, procedures and actions of the team. To put this change of priority into perspective, six months ago, sanitisation was not top of mind for people. Why, because it was not a life or death issue, we had other first world problems to garner our attention. From an operations perspective if we enabled a sanitization issue to become significant enough to impact the safety of customers and staff and therefore the brand, then that was an operational choice versus a mistake. Standards for sanitisation  Just like cybersecurity has had a direct impact on the IT strategy and budget, COVID will have a direct hit on the operations strategy and budgetThe issue is, today while the operating priority of sanitization has significantly increased, it is not measured and managed to the same standard as the other safety and security concerns across a business. Also, important to consider, while people may not hold an operation liable during this first wave, we can guarantee they are not going to be as understanding during the second wave or a future pandemic. To safely get back to business, the Centers of Disease Control and Prevention (CDC) and the Occupational Health and Safety regulators emphasis that all operations need a pandemic response plan and should follow these simple guidelines: Develop your plan Implement your plan Maintain and revise your plan While this sounds simple enough, keep in mind that requirements are constantly evolving and will continue to do so for the foreseeable future, or at least until all the research is in. To create an emergency response plan for a pandemic, properties must first determine what needs to be sanitized. The current requirements dictate that most surfaces and objects will just need a normal routine cleaning, it is only the frequently touched surfaces and objects like light switches and COVID has changed the game and made the digital transformation of operating procedures not a ‘nice-to-have’ but a must-havedoorknobs that will need to be cleaned and then disinfected to further reduce the risk of germs on surfaces and objects. The challenge is when you step back and consider what people touch in a day; the list quickly grows. After only 30 minutes, I easily came up with a list of over 60 items that one could call ‘high touch’! If you think about it, the list is extensive; telephones, doorknobs, drawer handles, counters, pens, keypads, computers, etc. and the list is only going to get longer as the research comes in.   The challenge is when you step back and consider what people touch in a day; the list quickly grows Operating efficiency  If we don’t change our ways, not only will we be doomed to continue making the same mistakes, but we will continue to be lost in paper and filing cabinetsTo scope the impact on operations as part of the plan, we must then find and identify all of those high touch things across the property. If we then combine that with the fact that CDC requires that all high touch locations must not only be cleaned more often, but that they also require that each location is first cleaned with soap and water, and then disinfected for one minute before finally being wiped down. This means a one-minute task just turned into a 4-minute task, that must now be completed multiple times a day. From a resourcing perspective this adds up quickly, and operating efficiency must be a priority. Not to mention it is going to get very complicated to measure and manage especially. Post COVID rules Getting back to business is going to be complicated; lots to do, lots of moving parts and no technology to help. The fundamental challenge to keep in mind is not that the sanitization requirements have evolved, the real issue is that for most businesses this area has been left unchanged for generations. Still today most rely on checklists, logbooks and inspections to manage the responsibilities of our front-line workers, which might have been fine before COVID. Post-COVID the rules have changed and so should the approach to managing physical operating compliance on the front lines. COVID like most physical operating requirements is tactical, detailed and specific; broad strokes, the honor system and inspections are not going to cut it. The digital transformation  COVID has changed the game and made the digital transformation of operating procedures not a ‘nice-to-have’ but a must-have. If we don’t change our ways, not only will we be doomed to continue making the same mistakes, but we will continue to be lost in paper, filing cabinets filled with checklists, never to be seen again. Only with the right data can we significantly improve the operational decisions necessary to accelerate our return to full operating capacity. At the end of the day, to fully recover, operations must eliminate the fear, uncertainty and doubt in the minds of customers and employees, only then can we really get back to business.

Which Security Technology Is Most Misunderstood, And Why?
Which Security Technology Is Most Misunderstood, And Why?

The general public gets much of its understanding of security industry technology from watching movies and TV. However, there is a gap between reality and the fantasy world. Understanding of security technologies may also be shaped by news coverage, including expression of extreme or even exaggerated concerns about privacy. The first step in addressing any challenge is greater awareness, so we asked this week’s Expert Panel Roundtable: Which security industry technology is most misunderstood by the general public and why?
