First, regardless of whether the resident is at home, absent, or at night, when the visitor approaches, the visitor is detected by the human body detecting means 1 provided in the intercom slave unit 2. By this detection, the microcomputer 32 operates, and the imaging means 3 captures a still image of the visitor's figure, transmits the still image to the intercom master unit 5 by radio, and records the still image on the interphone master unit side, ie, the non-volatile memory. And so on. At this time, taking into account, for example, incomplete imaging, the imaging, transmission, and recording are repeated several times at intervals of several seconds. In addition, in consideration of the capacity of the recording unit 20, it is also possible to adopt a method of recording only in a “monitoring mode” described later.

Next, when the visitor presses the call button 6 and the resident presses the response button 16, reception of a normal moving image starts. At this time, the recorded still image may be deleted when the resident responds, taking the capacity of the recording unit 20 of the intercom master unit into consideration.

The intercom master unit 5 is provided with a mode changeover switch 18 for switching between a "normal mode" used when a resident is at home and a "monitoring mode" used when absent or at night. Further, a confirmation lamp 17 for notifying the resident that a still image has been recorded is provided to prevent the user from being unaware that the still image is being recorded.

Confirmation of the recorded image is performed as follows in this embodiment.

Set the mode switch 18 to the "monitoring mode".
Side, and by pressing the response button 16 for several seconds, the recorded still image is displayed on the monitor 15.
Next, the image is switched by pressing the response button 16. If the confirmed still image is unnecessary, the confirmation lamp 17 flashes for a few seconds after the last still image is displayed. If the response button 16 is pressed during this time, all the still images are erased. If the response button 16 is not pressed, the data is stored as it is.

Of course, various confirmation methods are conceivable, such as a method of displaying a still image while confirming erasure one by one.

Next, the "monitoring mode" used when a resident is absent or at night will be described. This mode is switched by a mode switch 18 provided on the intercom master unit 5.

In this mode, the visitor approaches and the human body detecting means 1 repeats imaging, transmission and recording at intervals of several seconds. At this time, when the visitor presses the call button 6, the mode is temporarily switched to the "normal mode". "Monitoring mode" if there is no response from the resident for a certain period of time (for example, about 2 minutes)
Return to.

Next, another embodiment of the present invention will be described.
FIG. 5 is a schematic perspective view, and FIG. 6 is a schematic view of a main part.
