Video surveillance systems are quickly gaining popularity in transportation applications to ensure safety of all commuters. However, there are always issues when finding ways to supply power to remotely located devices and how to keep them operating 24/7 when they are constantly exposed to extreme weather. Recently, Advantech used PoE enabled Ethernet switches to overcome these inherent distance, power, and reliability issues.
There are a few critical issues when constructing remote video surveillance infrastructures. For instance, the distance between power supply and the IP cameras is typically very far and hard to set up. Additionally, a wide operating temperature is critical for harsh outdoor applications. In this case, IEEE 802.3af PoE support and an operating temperature range of -40C to 75C was required along with IP30 mechanical resistance and a flexible DIN-rail/wall-mount support.
EKI-2526PI - 6-port industrial PoE switch with 48Vdc power input with wide temperature range.
EKI-7659C - 8+2G combo port Gigabit managed industrial Ethernet switch
The EKI-7659C is connected to the control center to establish a network backbone allowing connectivity to the PoE enabled EKI-2526PI which in turn, provides the power and data to a series of remotely located IP cameras. This allows the administrator in the control center to directly manage all the IP cameras in the field.
PoE enabled devices can easily help solve the distance, power, and reliability issues that plague many industrial applications especially when connecting to a variety of remote devices. In this instance, the customer was able to avoid power wiring installation for the IP cameras and ensure reliable operation of the entire system.
