PROBLEM TO BE SOLVED: To provide an intercom device that records a video immediately after a camera is opened even if a call operation is performed in a state where the camera is closed.SOLUTION: A camera 102 of an entrance slave unit 1 comprises an illuminance sensor 115 for detecting surrounding lighting intensity. A master unit MPU 209 of a living room master unit 2 activates the camera 102 when the call operation is performed in the entrance slave unit 1, and controls so as to display an imaging video onto a monitor 202. Further, the living room master unit controls so as to light an illumination part 103 based on lighting intensity information obtained by measuring with an illuminance sensor 115 if a value of the lighting intensity is less than a predetermined value. If the value of lighting intensity is equal or larger than the predetermined value even when lighting the illumination part 103, the living room master unit determines an abnormal call operation and controls so as to start recording as a recording stand-by state after the value of lighting intensity recovered to the predetermined value or more.SELECTED DRAWING: Figure 1 |
