The IPCAMPOESPLIT, POE Splitter connects to the DC Jack and RJ-45 port of the Network Camera. A Cat-5 cable runs from the POE Splitter to a POE Switch to a maximum of 100 meters. One IPCAMPOESPLIT is required per Network Camera. The IPCAMPOESPLIT will supply a 12V maximum 1A precision regulated output. 4XEM Power Over Ethernet adapters have built-in ESD/lightning protection to help in preventing equipment damage due to transients and also have proprietary sensing algorithms which detect an overload or short circuit condition and shut down the supply to prevent equipment damage.
