Tram Surveillance

Overview

Environmentally friendly urban development policies all over the world make Ethernet tram the future trend of smart transportation systems. These Ethernet vehicles are integrating secure and reliable multifunctional solutions.  One of such an example is the deployment of on-tram ticketing systems integrated with IP surveillance and multimedia solutions. The multifunctional systems require devices which can overcome vibration and shock on moving vehicles and provide efficient network management tools for high quality video transmission. 

Regular RJ45 connectors used in such networking devices usually experience link failure and data loss under harsh exploitation conditions. That is the reason why M12 connectors are used; however, they require soldering and their deployment results in high wiring costs. Thus, in order to have a reliable, cost-effective connection and to overcome the vibration/shock on vehicle, rugged RJ45 connector is needed.

For the tram company Korenix JetNet 4506-RJ appeared to be the best solution, which solved all these problems and in addition reduced wiring costs of the total system providing fast and easy system installation. Equipped with rugged IP67 grade RJ45 connectors JetNet4506-RJ provided great protection eliminating link loss and data failure from constant vibration and shock.
The JetNet 4506-RJ rugged switch worked as an intermediate device assuring the data transmission from transit magnetic ticket validators and multimedia devices to the central room through GPS boards. It simultaneously transferred the video streams captured from IP cameras to the mobile NVR.

With its Rapid Super Ring redunancy technology JetNet 4506-RJ recovers any link failure and data loss within 5 ms providing a reliable video transmission. Besides, JetNet4506-RJ features VLAN and QoS management functions to guarantee the high quality of the video transmission, as well as optimized IGMP Query/Snooping to prevent multicast traffic from flooding the network while ensuring the high quality and efficient multicast multimedia traffic delivery to the tram. The versatile management interfaces of JetNet 4506-RJ reduce maintenance efforts and costs making it the best solution for this all-in-one tram application.
