Wireless Video Surveillance – Challenge or Opportunity?StarSight International Ltd 1
StarSight International Ltd 2Demand has never been greater for video surveillance systems in locations such as airports, event venues and city centers. As a result, organizationstasked with ensuring public safety and securing critical infrastructure are increasingly looking to deploy “wireless mesh” networks to extend existing wiredinfrastructure.
Why Wireless Mesh for Video Surveillance? StarSight International Ltd 3In terms of investment, the advantages of wireless mesh are signiﬁcant: initial capital and operating expenses (CAPEX/OPEX) are 1/20th of the totalinvestment for a similar wired infrastructure. Cost reductions of that magnitude are, by themselves, motivating customers to turn to wireless solutions. On the technical side, video surveillance systems require a great deal of ﬂexibility, and wireless mesh offers advantages there that wired systems justcan’t match. A mesh system can transport real-time wireless video, voice and data from just about any location across the network into its cloud. Camerascan be installed in buses or trains, ﬁxed on buildings, repositioned, added or replaced, and there’s no need to pull cable, drill holes or disrupt day-to-dayoperations. Wireless mesh networks can be deployed quickly, too. A network of wireless cameras can be deployed over one square mile in just a few weeks. There’sno system downtime impacting commercial or security applications, and─because deployments don’t require trenching cable,─there are usually nopublic safety issues or other disruptions like construction-related trafﬁc congestion.
Imagine a Traditional Wired Switch (Wired Ethernet infrastructure) StarSight International Ltd 4But ﬁrst, what is this ‘wireless mesh’ that I will be talking about? Let’s have a look. Imagine a traditional wired switch.
Now, Give Each Port Wireless Capability (Wired Ethernet infrastructure) StarSight International Ltd 5Now if each of those ports had its own wireless antenna, it would look like this…
Separate the Ports – Bingo, a Virtual Ethernet Switch! (Wired Ethernet infrastructure) StarSight International Ltd 6If we then physically separated those ports and eliminated the hard-wired distribution system, it would look like this. Essentially, the HotPort nodes in amesh network behave this way.
StarSight Firetide Wireless Infrastructure StarSight International Ltd 7In StarSight - Firetides view, true mesh networks are Ethernet-based and employ a fully distributed wireless switch infrastructure. Unlike point-to-point orpoint-to-multipoint networks, every node on a true mesh network can talk to every other node with full routing and switching capabilities, along withsecurity and application layer quality of service. Infrastructure mesh networks are dynamic, in the sense that each of a network’s nodes carries the intelligence to determine the quickest, most reliablepaths for delivering data. It is an architecture that’s particularly adept at load balancing large streams of video. If a path becomes overly congested or anode disappears altogether, infrastructure mesh is smart enough to dynamically re-route feeds to the next quickest path.

Chicago OEMC – City-Wide Surveillance StarSight International Ltd 9Wireless Mesh Fills the "Fiber" Gap The city-wide video surveillance system uses a combination of uniﬁed ﬁber and wireless mesh networking to make data available in real time. WithoutStarSight - Firetide wireless mesh, it would have been too difﬁcult and cost-prohibitive to install surveillance cameras everywhere they are needed.The combination of StarSight - Firetide technology and network design provides real-time, continuously streaming video from the cameras to the OEMCcommand center. Careful network design played a key role in StarSight - Firetides ability to deliver ﬂuid video, indistinguishable from the video providedby wired cameras. StarSight - Firetide mesh nodes are deployed in two dozen meshes spread out around Chicagos downtown area. The multi-meshconﬁguration provides sufﬁcient bandwidth for each camera on the mesh. Each mesh then connects via a "head node" to the city ﬁber, with ﬁberbackhauling the trafﬁc to the OEMC command center.
Chicago OEMC – City-Wide Surveillance 125 wireless cameras 550 cameras total Dense urban environment Harsh environmental conditions StarSight International Ltd 10Within one week of coming on board, StarSight - Firetide had its ﬁrst mesh network in place and transmitting video optimized to the exact speciﬁcations ofOEMC and IBM. Based on this success, IBM decided to use StarSight - Firetide for the remainder of the wireless project.Operating in the dedicated 4.9 GHz public safety band, StarSight - Firetide mesh delivers exceptional reliability and performance in a very dense urbanenvironment. Downtown Chicago has numerous high-rises and narrow streets, making for a challenging RF environment. The network performs well inthe uncompromising climate of the Midwest, withstanding the snow and freezing temperatures of winter, and heat and high humidity of summer.
Dallas – Downtown Surveillance StarSight International Ltd 11Dallas PD goal was to reduce crime in the downtown business district and to combat the perception of inadequate safety measures in the area. The policedepartment was pleasantly surprised at the speed of implementation and the tremendous support from the business community. While they did not go intothe project with the concept of wireless, the beneﬁts quickly became obvious: the mesh enables quick setup of the network without a complete overhaul,while providing excellent bandwidth and security for video streams.

Jubilee Park, Dallas – Neighborhood Surveillance StarSight International Ltd 17Jubilee Park is a neighborhood with a history of high crime: 80 percent of area residents report being victimized within the past year. To date in 2007,there have been six assaults, six robberies, and 25 burglaries in the Jubilee Park neighborhood, according to police records. In 2006, there was onehomicide, two rapes, 13 assaults, and 26 burglaries.StarSight - Firetide wireless mesh and Sony cameras have been installed at intersections throughout the community and are controlled by the DallasPolice Department, providing police with the capability to monitor activity in real time. "This system allows us to do things we normally cannot do in acommunity," said Dallas Police Chief David Kunkle. "It gives us 24-hour visibility. What citizens and businesses always want, but we cant provide, is apolice ofﬁcer on every corner. To an extent, this mesh network and these cameras allow us to do that."
Rockford, IL – Housing Authority StarSight International Ltd 18The mesh network operated by the Rockford Housing Authority connects outdoor video surveillance cameras wirelessly to a central location for livemonitoring and recording of the video feeds.The housing authority was able to deliver a technology-based solution to reduce crime and disorder in public housing. Immediately after the cameraswere installed, crime and loitering diminished immensely, and both our residents and employees are feeling safer. Equally as important, the installation ofthe cameras has helped to improve the perception of public housing especially to prospective residents. Knowing that these cameras are up andmonitored, those who live in and around public housing can better understand the business impact a safe environment has on a community.

NASA Dryden – Asset Protection AgileMesh ™ Rapidly Deployable Video Surveillance StarSight International Ltd 22Ofﬁcials at NASA’s Dryden Flight Research Center in Edwards Air Force Base, CA, were told they had 60 days to ﬁnd a way to protect multi-million dollargovernment research aircraft in a satellite hanger in Palmdale, CA. Because NASA moved the planes into the hanger much sooner than the security teamhad anticipated, they didn’t have the typical time needed to specify, procure and install a ﬁxed surveillance system.The cameras around the perimeter transmit evidence-grade video from the hanger to the operations center. The video is monitored by staffers in theoperations center who can, if necessary, contact patrol units within seconds. The video is stored for 30 days for incident review and investigation. Ofﬁcialssay it has already helped improve enforcement of safety procedures.NASA ofﬁcials can now maintain stringent government security standards without installing a bulky, expensive security system that is tough to use andtougher to maintain. The Dryden Aircraft Operations Facility has an easy way protect multi-million dollar research aircraft, while providing valuableevidence for security and safety investigations.
Dubai Tower – Construction Site Security StarSight International Ltd 23Samsung Corp. recently deployed a StarSight - Firetide mesh network at the construction site of the tallest free-standing structure in the world, the BurjDubai (Dubai Tower), in United Arab Emirates. The newly installed StarSight - Firetide network is being used for video surveillance, VoIP (voice over IP),and RoIP (radio over IP) applications at the worksite.The Burj Dubai is scheduled to be completed by the end of 2008 and will rise over 2,275 feet high. Initially, communication in and around the site wasaccomplished using traditional walkie-talkies - easily transportable, battery-powered radio handsets. However, as the building grew taller, this means ofconnection became less and less reliable.
Critical Success FactorsStarSight International Ltd 24
Critical Success Factors Draw from multiple sources of funding Departmental budgets, government funding, private grants Address privacy concerns head-on Written guideline or court orders, where necessary Anticipate staffing and training needs Learning curves for installations and monitoring Partner for success Municipal departments, constituents, suppliers Consider the total infrastructure Backhaul options (wired or wireless); cameras; monitoring software StarSight International Ltd 25Draw From Multiple Sources of FundingInvestigate various sources of funding, which may be available from departmental budgets, homeland security grants, and even private grants.Additionally, a public safety network can be securely augmented to provide more services such as public Internet access and voice over IP.Address Privacy Concerns Head-onFor overt surveillance, adopt written surveillance guidelines and ensure personnel are properly trained. Inform affected constituencies – residents,businesses, and media – ahead of time; open communications and public demos are well received. For covert surveillance, reassure the public and themedia that the surveillance is conducted strictly within the law.Anticipate Stafﬁng and Training NeedsPolice personnel need training on the new monitoring technology, for example remote camera management or mastering the video managementsoftware. Learning curves may vary; allow for this in the training process. For large surveillance projects, a creative approach is to hire retired policepersonnel who may be interested in working part-time in the monitoring room.Partner for SuccessSeek out system integrators and suppliers who are comfortable with wireless and IP technologies and who will support you. Interagency cooperation isalso essential for rapid deployment.Consider the Total InfrastructureIdentify the backhaul options (how you will connect the wireless mesh to the monitoring station) early in the planning stages. Wired and wireless are bothviable options; backhaul can be dedicated or shared with other local government applications.
Walkthrough and Site Survey Start with feasibility walkthrough Obstructions Access to mounting locations Backhaul and power availability Formal site survey is NOT optional Rule of thumb: 10-20 camera locations/day Include: RF environment, path profiles, path calculations, projected performance per node, site information, antennae, cabling, power, backhaul, enclosures, bill of materials, deployment schedule, site photos Require written documentation StarSight International Ltd 26Start with Feasibility WalkthroughVisit potential surveillance sites and note any obstructions: trees, buildings, pedestrian and vehicular trafﬁc.Also consider access to mounting locations and availability of power and backhaul.Ensure that a Formal Site Survey is PerformedA formal site survey provides a solid “roadmap” for your deployment.Include RF environment, path proﬁles, projected performance per node, antennae, cabling, power, backhaul, enclosures, bill of materials, deploymentschedule, and site photos.A written document makes sure that expectations and timeframes are properly set.
Network Design Thorough network design and bandwidth planning are crucial Ensure clear line of sight between nodes Use multi-mesh topology Use high-gain, directional antennas Specify high-quality encoder if analog cameras are used Sector antennae Patch antenna StarSight International Ltd 27Thorough Network Design and Bandwidth Planning are CrucialWhen designing the mesh network, ensure that the network provides sufﬁcient throughput and low latency.To maintain high-performance, establish clear line of site between nodes.Specify high-gain, directional antennas;Can use omnis, but only in very speciﬁc circumstances – when nodes are close together and at the same elevation, with clear RF line of sightUse a multi-mesh topology – meshes interconnected by wired or wireless backhaul – to provide maximum bandwidth for each camera.
Network Tuning Optimize mesh configuration after installation Strong link quality required (1.5 ms latency per hop optimal) Eliminate weak RF links Manually set the link speed for best video performance Keep HotView Pro running continuously 24/7 monitoring of link performance Investigate intermittent outages or interference problems StarSight International Ltd 28Optimize Mesh Conﬁguration After InstallationIn any RF installation, there will be node-pairs with weak RF connections.You will improve performance, if you manually eliminate weak links, leaving only the strongest ones.We also recommend you manually set the link speed, rather than leaving all links to auto-negotiate the speed.You will avoid “link ﬂapping” (intermittent connectivity), which is detrimental to video performance.
Camera Settings Consider camera settings Is full-motion and full-resolution video really required? What compression is acceptable? What are the camera defaults? Unicast vs multicast traffic (Fewer cameras per mesh with multicast) Bandwidth per camera Manage requirements to “right-size” the network StarSight International Ltd 29Consider Camera SettingsAs you embark on the video surveillance project, be clear about performance requirements.Is full-motion and full-resolution video required?What compression is acceptable?Realistic performance requirements will help you avoid over-engineering the network.Instead, you can achieve greater coverage for the same project cost.
