FIELD: information technology.
SUBSTANCE: monitoring circuit (s) can detect a non-functional power supply state (IEPC) in the power line of the network peripheral device. When an IEPC state is detected, the power supply can be provided to the peripheral device by the backup power source. If a connection failure is detected between the peripheral device and its packet receiver, the packet receiver emulator can emulate the packet receiver of the specified peripheral device.
EFFECT: providing backup power supply to the network peripheral devices, such as video cameras.
