An information recording apparatus for recording information obtained from a sensor, comprises: a face detecting unit for detecting a face of a person among the information obtained from the sensor; a face detection switching unit for switching a control of the face detecting unit between valid and invalid; a face detection setup information obtaining unit for obtaining information of whether face detection set up by the face detection switching unit is valid or invalid; a face detection observation unit for observing on whether detection is made on the face or not, when the face detection is valid; a power-saving controller unit for executing a power-saving control; a recording unit for record the information inputted from the sensor onto a recording medium; a recording observation unit for observing on whether recording of the information is conducted or not by the recording unit; a memory unit for memorizing information necessary for controlling the information recording apparatus; and a controller unit for controlling each constituent elements mentioned above, wherein the controller unit executes a control for reducing an electric power consumption of the information recording apparatus, by the power-saving controller unit, when determining that: the control of the face detection unit is valid from the face detection setup information obtaining unit; face detection is not made on the face of the person from the face detection observation unit; and recording of the information is not made from the recording observation unit.
