A monitoring circuit(s) may detect inoperable electrical power condition(s) (IEPC) on the power-line of a network edge device. Upon detection of an IEPC, a backup power source may provide electrical power to the edge device. Upon detection of a connectivity fault between the edge device and its packet sink, a packet sink emulator may emulate a packet sink of the edge device. ## Claims ### Claim 1 A video camera power backup apparatus comprising: a Power over Ethernet (PoE) adapter to receive and connect to a Direct Current (DC) PoE power line originating at a PoE source and further adapted to output: (i) an internal power line carrying power received through the PoE power line and (ii) a data line carrying data received from the PoE source;
