Tunnel Traffic Monitoring
Overview
 The disastrous fires and everyday accidents lead to a major reappraisal of tunnel safety. As a result, latest video surveillance technologies are being installed to ensure the highest level of safety and fast reaction in emergency situations. However, some challenges need to be addressed, including the relatively humid, dusty and salty environmental conditions in tunnels, the frequent vibration of equipment caused by moving heavy vehicles, etc. For the system integrating company Korenix JetNet 3706-RJ appeared to be a great solution, which solved all these problems and, in addition, reduced the impact to heavy traffic by shortening the construction and future maintenance time. JetNet 3706-RJ rugged switches installed in underground tunnels powered the IP cameras and transferred the captured streams to the monitoring center. To overcome the long distance between the traffic center and the pole, JetCon 3401G gigabit media converters where used as intermediate devices.
With six IP67 rated RJ45 ports, the JetNet 3706-RJ make it possible to extend power deployments to the most inaccessible areas and reduce maintenance time, thus the overall costs, to  o. Due to its outstanding mechanical design and cap ability of operating in -40 ~ +70oC wide temperature range, JetNet 3706-RJ can be easily adopted in difficult to wire tunnel applications providing the most rugged solutions for reliable IP surveillance network construction. outdoor PoE switches are easy to install. As a result, they reduce wiring costs and provide secure and highly reliable waterproof, dust-tight, anti-vibration connection. In addition, the 4 PoE ports of The real-time traffic monitoring of tunnels from the control center is becoming possible when additional JetCon 3401G gigabit converters are installed. These converters receive millions of video streams from IP cameras via JetNet 3706-RJ and through gigabit optic fibers transfer these high bandwidth data to the central room. With its rugged design in addition to the excellent traffic handling and the active link loss forwarding technologies, JetCon 3401G enlarges network performance and keeps the data transfer running non-stop in severe conditions.
The overall network system provided by Korenix, with the installation of JetNet 3706-RJ and JetCon 3401G became an ideal efficient and cost-effective solution for the System Integrating company to design a real-time traffic management and monitoring in harsh tunnel applications.
