    Lower Your Costs of Video Streaming Over CellularAs anyone who has encountered echoes, stuttering voices, and out-of-sync movements on a video call knows, live streaming isn’t always what it’s cracked up to be.What you may not know is that cities are starting to experience similar problems as they connect cameras to everything from highways and railways to town centers and streetlights. For municipalities, the benef i ts of streaming video are compelling. They can literally see events as they unfold, responding more effectively to emergencies and eff i ciently organizing crews to deal with traff i c jams and crowded public events.But just as it does for consumers, video streaming can have signif i cant limitations. Coverage is often uneven, and video is extremely data-intensive, creating a heavy load on city cellular networks. That can lead to lags and drops in service at critical times—not to mention sky-high bills.New technology can overcome many of these obstacles, delivering video more eff i ciently across a broader area with almost no latency. With 24/7 video streaming over cellular you can achieve reliability, near-zero latency, and high video quality. As a result, cities can obtain a more accurate picture of operations and events, while also securing their data and saving taxpayers money.Near-Zero Latency Lowers Operational CostsSmart cities have a twofold problem with video streaming. In densely populated urban spaces—especially if a big sports game or other live event is happening—cellular networks can quickly become clogged. In rural areas, cellular service may not be available, or the signal may not be strong enough for video transmission. That can leave cities with large swaths of the community they can’t access in case of an emergency or disaster, as well as blind spots along streets and highways.“Live streaming video across cellular networks is not only diff i cult, it can be extremely expensive,” says Fredrik Wallberg, Chief Marketing Off i cer at Digital Barriers, a provider of video solutions for municipalities and businesses. “To pull reliable video, you need to push down the data usage and the bandwidth requirements.”After years of working on video technologies for government organizations in the U.S. and Europe, Digital Barriers leveraged its expertise to do just that. The EdgeVis video router, powered by Intel ® processors, compresses video data, resolving congestion and improving reliability on fi xed networks for near real-time data transmission, even in remote rural areas.“Cities can use it for streaming over 3G, 4G, or 5G from anywhere. Independent testing by telecom companies has found there is anywhere from 50% to 90% savings on cellular costs,” Wallberg says.Managers can also use the router to regulate their departments’ video camera use, ensuring the city doesn’t exceed its data plan limits and incur overage fees.Real-Time Video for Emergencies and EventsObtaining affordable and reliable coverage could encourage cities to expand video streaming. One of the most vital use cases is emergency response. With accurate, up-to-the-TECHNOLOGY BRIEF
