A Reliable Surveillance Network- Poe Switch
WithJetNet 5428Grackmount ring switches have been recently installed in a Railway
Station in Europe to provide real-time video surveillance and enhanced passenger information system. Through the eight 802.3at high power PoE ports the switches provided connectivity to the large number of IP cameras and PoE enabled devices on the station platforms, while ensuring the uninterrupted and long-distance communication of megapixel video through the formed MSR fiber rings of its Gigabit Ethernet combo ports. With their rugged design that exceeds the EN 50121-4 Railway EMC requirements and -40~75oC operating temperature range, the switches became the best solution to resist harsh environments at the modern rail station surveillance and PIS (Passenger Information System) project.To know more about Gigabit Ethernet combo ports, click here.
Monitoring train operation, track status for preventing accidents on the railways, as well as providing real-time information to passengers on the stations and inside carriages has become of great importance today. And as video has upgraded from analog CCTV to megapixel video imaging, system integrating companies are looking for high-bandwidth solutions which can ensure efficient live surveillance of the large scale applications while satisfying passengers needs of high quality and valuable data. Moreover, to resist the severe industrial challenges on the railways, these solutions should be highly robust.

Addressing the main concerns for security at the railway system, the system integrating company in Europe installed large number of megapixel cameras, LCD or LED information displays on the stations together with KorenixJetNet 5310Gruggedized high power PoE switches to provide a reliable surveillance network. Each switch was able to deliver 30W power to up to 8 high power PoE enabled devices, such as IP cameras, multimedia displays through its PoE ports, while simultaneously collecting the captured video streams and other data, as a result greatly saving installation and cabling costs.
To extend the captured videos from the PoE switch to theJetNet 5428Grackmount switch in the control room and transfer train schedules, administration announcements, advertisement and emergency evacuation alert messages back to the station LED/LCD displays, the uplink gigabit Ethernet fiber ports of the switches were used for data extension over fiber. And as both switch models supported Korenix Multiple Super Ring redundancy protocol, the railway operator was able to form a fiber ring for transferring the real-time data with no loss or system collision.
