Scale up to a ONE Gigabit Network
Today's traffic surveillance technology plays an essential role in both accident detection and traffic management, thanks in large part to the rapid growth in the practice of transmitting video, voice, and data over Ethernet and the Internet. Before IP networks became prevalent, video, voice, and data were managed using completely different protocols and systems (including analog systems). Due to the current demand for delivering video, voice, and data over ONE network for traffic surveillance applications, system integrators are always on the lookout for networking products that support larger bandwidths and greater media versatility. One of the requirements called for most often is gigabit Ethernet, which can be used as a backbone to provide a higher bandwidth network for traffic surveillance applications, to ensure that all information is transmitted smoothly.
Maximize the Transmission Distance
Surveillance cameras at major intersections provide an effective means of reducing red light violations, and as a result improve transportation safety dramatically. In addition, by sending data from multiple intersections to one central control room, traffic engineers can better control traffic flow and reduce traffic jams. However, most computers in the central control room use gigabit LAN adaptors with RJ45 connectors to connect to each other, and the 100-meter limit for transmitting data over twisted pair cable makes it difficult to link to remote sites. Since the distance from intersections to the central control room could be as much as 40 kilometers, using twisted pair cable would require installing Ethernet switches every hundred meters or so, making maintenance both difficult and expensive. The IMC-101G gigabit media converter is an attractive and economical solution to this problem, since the transmission distance can be extended up to 80 kilometers (over single mode fiber) at gigabit speed. As an added benefit, each IMC-101G converter comes supports Link Fault Pass-Through to ensure that the network runs non-stop, and to give system maintainers an efficient means of troubleshooting broken links.
