System Apparatus and Device for Facilitating Network Edge Device Backup and Methods of Operation Thereof

摘要

Disclosed is a system apparatus and device for facilitating the backup of network edge devices, such as video cameras, and methods of operation thereof. 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. The disclosed system apparatus and device may implement a Power over Ethernet (PoE) power backup device for providing power to one or more edge devices, the device comprising: a PoE input port, an auxiliary power input port, a PoE output port, a power storage circuits, and power management circuits for detecting available power, switching between power sources, and regulate the power switching based on power detection outputs.

1. A Power over Ethernet (PoE) power backup device for providing power to one or more edge device, said device comprising:
a PoE input port to receive an Ethernet line from an Ethernet switch; an auxiliary power input port to receive power from a low voltage power-supply; a PoE output port to connect with an Ethernet line to a PoE enabled edge device; a power storage circuits to store electrical power; and power management circuits comprising: (a) power detection circuitry to detect available power on the PoE input port and on the auxiliary power input port; (b) power switching circuitry to switch available power from either of the input ports to the PoE output port, to the power storage circuit, wherein said power storage circuit includes a power storage element and a charging circuit to charge the power storage element with switched available power from either of the input ports not used by PoE enabled edge device; and (c) control circuitry to regulate the power switching circuits based on an output from the power detection circuits.
