Undoubtedly, the operating environment of tunnel is harsh coping with humid with extreme temperature and pollutants in a tunnel generating by cars and other moving vehicles, the vibration caused by moving vehicles is another challenge for network devices. Thus, a reliable Ethernet network is the top priority for tunnel traffic monitor application.
Lantech industrial switches are able to sustain in tunnel projects by providing our high-quality industrial switches with redundancy of network recovery scheme. The Ethernet-based network connects IP CCTV, audio PA, telephones, VMS (Variable Message Signs), lighting control and ventilation fans (SCADA system) and also some traffic control systems for management remotely.
Lantech managed switch support full management functions, including the IGMP protocol for multicasting, which is important for video transmission. To against the harsh environment, Lantech models operate well in the range from -40°C to 75°C and also pass several stability and safety test including vibration, free fall, shock, EMI and EMC, to meet the difficult tunnel environment.
Lantech products help to construct a highly reliable network connection by ITU G.8032 Ring system, which is the most important factor for an efficient traffic monitoring system, under the harsh environment in tunnel./p>
