In order to meet these stringent criteria, law enforcement units around the world are turning to California-based TVU Networks, a leader in IP-based live video solutions. Long a standard among large broadcast station groups, TVU’s cost- effective, simple-to-use digital technology offers the best-in- class solution for delivering live video over wireless networks. Whether performing surveillance or emergency response, TVU’s solutions leverage into existing workﬂows to help organizations transform traditional hard-wired operations to a predominately wireless IP-based infrastructure. They’re designed to be ﬂexible and scalable, so the platform can grow and change with the organization’s needs. In one major American city, the police force was able to see immediate beneﬁts from their TVU system when faced with keeping the peace during a series of large demonstrations in the city center. A tactical commander observes, “We used four simultaneous video feeds, three from ofﬁcers set up on rooftops or moving on foot through the crowd, and one from a helicopter monitoring crowd movements from the air. Then we displayed the video on a twenty-foot screen in our Emergency Operations Center. This live view of the action was critical in effectively managing our response to keep a potentially volatile situation from getting out of hand. When making decisions, there’s nothing like actually seeing what’s going on.” The fact that the TVUPack is easy to operate is a big plus. The commander adds, “The fact that the TVUPack is easy to operate is a big plus. All our ofﬁcers have to do is plug in the camera, push the button, and we have live video. The ofﬁcers carry the transmitter on foot because it’s so lightweight, but we can also quickly transition to any vehicle and move to other locations without losing the video stream.” It enables TVU systems to deliver superior HD picture quality wirelessly from even the most remote, bandwidth-challenged locations (including moving vehicles) to hardware video decoding receivers at operational headquarters, with under one second end-to-end delay through multiple transmission mediums. It supports multiple cellular 3G/4G LTE, microwave, satellite, WiFi, BGAN and Ethernet connections. The company’s mobile transmitter series are a family of small, lightweight, powerful transmitters, available in backpack style or ultra-compact models weighing less than three pounds. Their simple operation needs no in-ﬁeld conﬁguration. Just plug the unit into the camera source, press the green button, and begin transmitting real-time video on the ﬂy. The transmitters are operational in less than 20 seconds from a cold start, and some feature dual hot-swappable batteries that offer up to seven hours of continuous recording. For added versatility, the TVU Anywhere mobile app allows any smart device to capture and transmit live video, giving tactical commanders even greater access to events as they happen. TVU’s transmitters feature powerful dual encoders that enable not just live transmission, but onboard recording for later on- demand retrieval as well. If wireless network connectivity is lost, the internal hard drive continues to record full HD video, allowing the stored content to begin forwarding once the connection is restored. This encoding technology also allows the uninterrupted feed of video shot on the move by foot or vehicle. On the receiving end of the signal, TVU Grid offers streamlined switching, routing and distribution of all live video transmitted from the ﬁeld. Accessible through a web browser, TVU Grid provides the ability to seamlessly switch incoming content with the click of a button, and share live video streams with the command center as well as remote tactical units and mobile devices. Elite law enforcement and tactical operations worldwide have successfully deployed TVUPack and TVU Grid, to capture and distribute content in real time, assess situations quickly, make proactive decisions and implement an effective response. For both large-scale incidents and day-to-day operations TVU is an ideal choice that can help all types of agencies revolutionize the way they operate. Remote terrain, poor weather, nearby buildings or electromagnetic interference can make it difﬁcult to achieve sufﬁcient bandwidth for live video transmission. In response to this challenge, TVU was the ﬁrst to offer a hybrid transmission solution, seamlessly aggregating bandwidth by transmitting simultaneously over all available cellular, satellite, microwave, MIMO Mesh, WiFi, Ethernet and BGAN connections. Its proprietary advanced forward error correction algorithm, Inverse StatMux Plus (IS+), along with the TVU264 enhanced H.264 encoding engine, allows users to maximize the bandwidth available on each network connection and transmit the best possible picture. It automatically adapts to the transmission network environment, delivering dependable and stable HD quality even in locations with weak or compromised connections.
