Real-time & cost-effective bus surveillance

Korenix JetNet 3810G series vehicle PoE switches have been recently integrated in a bus surveillance project in Europe for enhancing passenger security and providing real time remote control for administrators. The switches with 8 PoE ports perfectly met all the requirements set out by the bus company for powering Axis cameras while delivering high quality and high speed data through the gigabit connection. Moreover, the exclusive booster technology added more value to the rugged switches making them excellent, cost-effective solutions for remote bus surveillance.

Thanks to the recent developments with IP cameras as well as wireless networking, remote monitoring of buses and instant response to critical issues has become a reality, widely used by almost every bus company worldwide. Yet, some challenges need to be addressed when building efficient network infrastructure, including the power conversion for driving 48V cameras from standard 24V on bus, and most importantly the unstable environmental conditions: temperature variations, vibration, shock etc.

To efficiently build a network with minimized costs, Korenix JetNet 3810G series PoE switches have been chosen by a European bus company for their 8-PoE port capacity - a unique solution in the market which enables users to save costs of implementing separate PoE devices in buses. The total project included installation of 1000 switches.

A single switch has been installed on-board of each bus with the capability to connect, power and transfer the captured video images from six Axis 206-FD IP cameras. The switch, powered up by 24VDC from the bus ignition system, automatically converted it to 48V power output via the exclusive Korenix PoE boosting technology for powering up the Axis cameras. Total of 65W budget was released from the switch to power up each camera by 15.4W. The collected video streams were then uplinked to the NVR through the gigabit port for recording the video images, while the second gigabit port was used to transfer the data to the wifi router, which then wirelessly transmitted it to the bus controlling center.

By using the port link failure alarm function, administrators were able to fast react to any failures in the system by Diagram of European Bus Surveillance network infrastructure receiving automatic warnings, as a result ensuring uninterrupted data transmission.

The rugged design of the JetNet 3810G with vibration and shock resistance and -25~60^oC operating temperature range guaranteed the reliable operation of the switch on the bus.

By using Korenix’s PoE solution, Bus Company greatly saved installation and maintenance costs of Network infrastructure, as a result delivering high quality and real-time video to the users, and thus improving passengers’ security while on the move.
