Bus Surveillance by 24V PoE Switch

Korenix JetNet 3705-24V, the 24V PoE Switch specifically designed for transportation surveillance, has been recently adopted in a bus surveillance system to increase the safety of the passengers. With the exclusive 24V PoE technology, JetNet 3705-24V simply connects the dots of the system as well as reduces its total cost. It overcomes the harsh condition on the moving vehicle and ensures network reliability by its rugged design and wide operating temperature. All these features make JetNet 3705-24V the best choice for IP surveillance on public vehicles.

Video surveillance in buses and other mobile systems has become highly important due to the increased number of criminal threats. With surveillance now heading its way of IP, more vehicles are being equipped with IP cameras which require a total IP surveillance network solution.

Bus surveillance, unlike other applications with available DC48V power input, has a different requirement, the DC24V power input. Therefore, the legacy solution to power 48V PoE cameras in their vehicles requires an extra power adapter for converting voltage from DC24V to DC48V. Usage of this additional device obviously increases the cost of the system while decreasing its efficiency.

To solve this problem and to lower the total cabling costs, the System Integrating Company opted to use Korenix JetNet 3705-24V PoE switch. The four 24V PoE ports power the IP cameras and the wireless AP. The videos from IP camera are stored in the mobile NVR and transmitted to the network surveillance center through wireless communication.

The JetNet 3705-24V 5-port Industrial PoE Ethernet DIN Rail Switch provides a high speed, simple and cost-effective solution for configuring small Industrial Fast Ethernet networks. The 24V operating voltage is supplied through a rugged terminal block which can be configured for redundant power connection. The vibration resistance, wide operating temperature and fan-less design with unmovable parts, made JetNet 3705-24V the ideal solution for this application.

The Korenix patented 24V vehicle PoE technology makes the deployment of standard IEEE 802.3af PoE IP cameras feasible on school and transit buses, railcars, ships and other public vehicles.
