PROBLEM TO BE SOLVED: To provide an intercom device for two households for surely reporting a message to the resident of a called household without urging a visitor to record the message even when the other household which is not the household called by the visitor responds. SOLUTION: In the intercom device for two households, when a first living room master unit set to a transfer mode is called (S1), the control part of the first living room master unit transfers (S2) a call to a second living room master unit, and also transfers (S4) video signals (S3) received from a first entrance slave unit. Simultaneously, the video image of the visitor picked up in response to a calling operation is recorded in the sound/image recording part of its own. When speech communication is performed (S7) between the first entrance slave unit and the second living room master unit, it is detected and sound recording is performed together in the sound/image recording part wherein video images are recorded.
