Alvarion's surveillance solution enables deployment of expandable CCTV system at Port Botany

About the Port Botany expansion project:The Sydney Ports Corporation is expanding its container port facilities at Port Botany to augment long-term trade growth. Involving the reclamation of 60 hectares of land, this is the largest port project to be undertaken in Australia in over three decades. The Sydney Ports Corporation mission is to add value to all aspects of Sydney's port operations by managing and developing port facilities and services to meet existing and future trade needs and deliver profitable business growth.About Orion Integration:Orion Integration is an industry-leading security systems integration and development concern operating in Australia and the U.S. The company specialises in innovative, cost-effective solutions based on integrated research and development, manufacturing, installation and ongoing support, to provide tailored solutions to its diverse client base.The challenge:In order to monitor the progress of this ambitious project, the Sydney Ports Authority needed to deploy a CCTV system that would expand as the project progressed. With cameras positioned at heights of over 25 metres in the marine environment, the wireless infrastructure and cameras would be exposed to extremely harsh climactic conditions. In addition, the fact that the Port Botany expansion is located just 200 metres from a Sydney Airport runway and the entire Port vicinity is subject to unprecedented heavy RF congestion, the license-exempt wireless infrastructure had to be extremely directional and narrow. Coupled with this was the need to overcome obstacles on-the-fly, such as moving shipping containers. The solution: Alvarion's cost-effective BreezeNET solution was chosen for the backbone of a native IP network of Point-to-Point links   Alvarion's cost-effective BreezeNET solution was chosen for the backbone of a native IP network of Point-to-Point (PTP) links. A series of Pelco and Sanyo 4-megapixel HD Pan/Tilt/Zoom cameras are dispersed throughout the site; with each covering a 200 metre range. The multi-vendor cameras transmit 2288x1712 HD video over a single backhaul link at a rate of 20 mbps. This unprecedented resolution allows better monitoring and greater detail, supported by up to x10 optical magnification.Because of the higher bandwidth, HD video can be transmitted live and does not need to be stored and processed at each camera site. This is an important operational advantage given the difficulty of maintaining dispersed hard disks that are exposed to harsh weather conditions.A centrally-managed hard disk system not only reduces costs; it improves the integrity of the data. Orion also installed local recording for additional redundancy. Alvarion's robust PTP wireless link ensures that obstacles are easily overcome, such as shipping containers being transported and moved throughout the site. Supported by the wide reach of the Pan/Tilt/Zoon cameras, a series of ad hoc PTP links can be simply deployed throughout the dynamic, constantly-changing site whenever needed.The result:Alvarion's BreezeNET B100 solution is enabling cost-effective progress and gradual upgrade of proprietary sections of the existing network. This ensures that the entire Sydney Port complex will be equipped with a very high-definition wireless NVR system that is expandable and ready for ongoing security and access control long after the Botany Port expansion project is completed.

Alvarion's transmission system improves public security in Ivory Coast
Alvarion's transmission system improves public security in Ivory Coast

The recorded CCTV images are transmitted via Alvarion's wireless network to a central control roomAbout Basic SecurityA leader in the field of security solutions in the Ivory Coast, Basic Security provides its customers with a wide range of services including; video surveillance, monitoring using alarm systems, fleet management, and geolocation VIP protection. Basic Security supports its customers from the initial planning stages through customising the solution, installation and ongoing support.The challengeIn order to provide CCTV and security services to the residents of Abidjan, Basic Security was using an existing network based on wired lines. However, the company faced a number of challenges including the high cost of leased lines; low quality services due to limited bandwidth of only 128 Kbps, and insufficient coverage to provide connectivity to all the critical areas in Abidjan. As a result, Basic Security sought a wireless solution that could answer these challenges and enable them to improve public safety and security for the residents of Abidjan.The solutionBasic Security selected Alvarion because of their good market reputation, product quality and availability and high-capacity solutions. The wireless network was built using the BreezeACCESS VL and SU54 subscriber unit to provide point-multipoint coverage and the BreezeNET B300 for high-capacity point-to-point access. The network also includes several analogue cameras positioned in key locations across Abidjan. The recorded images are transmitted in high-quality to a central control room where they are monitored and used to identify incidents that jeopardise the city's security and safety.The resultAlvarion's cost-effective network has enabled Basic Security to offer improved security services to the residents of Abidjan and as a result, public safety has increased significantly. The high quality video images transmitted to the control room have enabled the police to catch many offenders including several men who broke into a football stadium and some who were attempting to assault a woman. In addition to security services, Basic Security is now also able to provide connectivity to businesses that were previously outside the coverage area and could not benefit from broadband access.

Alvarion wireless network offers robust, reliable and mobile solution for international airport
Alvarion wireless network offers robust, reliable and mobile solution for international airport

The challenge The airport required both fixed and mobile communications systems. The fixed system was required as a back-up communications system for the main fibre optic communications network. The mobile system was required for security operations based on mobile vehicles. Wireless broadband was recognized as the best solution, particularly because it eliminates problems with wired infrastructures (which can be damaged during on-going construction activities) and also works freely as a mobile solution. About Talcom Talcom specializes in the integration of wireless systems, including the planning, implementation and maintenance of wireless communications solutions. Representing leading international wireless companies, the company's customised and comprehensive solutions have been used in a range of projects around the world, including wireless data and video communications solutions at several airports around the world, from the USA and Israel to Thailand, Italy, Cambodia and Eastern Europe. Talcom is an AlvarionExpert Partner.    Wireless Communications system used for mobile connectivity The Solution Once the first phase of establishing the initial security infrastructure (such as fences and wired communications) was completed, a second phase focusing on the mobile solution began in 2005. Following extensive field trials with a number of vendors, Alvarion was selected as the only vendor capable of providing continuous full video streaming for moving vehicles, and after a short implementation period, the project went live at the end of 2006. Today, the solution consists of 70 outdoor cameras, some of which are thermal for night vision, 5 patrol vehicles equipped with custom-made suitcases offering full mobility and seamless roaming capabilities, and 5 base stations. Offering more than 10 Mbps throughput per vehicle and over 20 Mbps for clusters of video cameras, the solution covers the whole range of the airport (4 x 8 km). The Result This deployment is a complete, mobile integrated security solution that connects buildings and provides 24/7 video surveillance and voice connectivity. The data services are both a back-up for fibre-based building connectivity, as well as part of the mobile solution application which also offers video and voice services. Consequently, security personnel on patrol have full flexibility, even when having to step out of their vehicles, since they are permanently connected to the network, from their PCs in their vehicles to their PDAs and Wi-Fi phones, enabling them to control cameras from their vehicles or PDAs. Since the solution went operational, there has been no down-time and it has not been necessary to replace any wireless device.
