So much can be said about the evolution of the Surveillance industry and probably the number one topic these days is the transition to IP Networks, PC Based DVRs, NVRs, and IP Cameras. Much goes into finding out how many Mega Pixels a Camera has. How powerful is the network or software. But one minor detail that plays a vital role in this new age of CCTV is the PoE (Power over Ethernet).
A PoE switch is an Ethernet switch that sends power as well as data through the Ethernet Cable. Standard PoE requires CAT5 cable. So when a Complete IP system is being considered it’s also important that as much research is done on the PoE switch as the cameras themselves. Most advocates expect PoE to become a global long-term DC power cabling standard and replace “wall wart” converters, which cannot be easily centrally managed, waste energy, are often poorly designed, and also easily vulnerable to damage from surges and brownouts.
It’s important to pay close attention to the Power being distributed from the PoE switch to accommodate all of your IP cameras. It makes no sense to invest as much as possible in quality IP Cameras and fall short on supplying the cameras with the proper PoE switch.
