Next, the operation for storing a visitor will be described with reference to the flowchart of FIG. As shown in FIG. 3, when the operation means 144 such as a call button of the outdoor child device 40 is operated (steps S1 and S2), an image of the visitor is captured by the image detection means 141 after a predetermined time (step S3). Then, it is determined whether or not there is a response from the indoor parent device 20 and the indoor child device 30 (step S4). If there is no response, it is next determined whether there is a memory remaining in the visitor data storage means 125 (step S5). If there is a memory remaining, the captured image data is stored in the visitor data storage means 125. (Step S6). At this time, as the data to be left as the visitor history, in addition to the image data of the visitor, the date and time data and the audio data before and after the image data is captured are also stored.

In step S4, if there is a response from the indoor master unit 20 or the indoor slave unit 30 in response to the operation of the outdoor slave unit 40, the image or the like detected by the image detecting means 141 is used as history data as visitor data. These data are discarded without being stored in the storage means 125. Also, in step S5, if the remaining memory capacity for storing in the visitor data storage unit 125 is exhausted, old visitor data is deleted and new visitor data is stored (step S9, step S6).

In the above embodiment, the image detecting means 141 is provided only in the outdoor slave unit 40. However, the image detecting means 141 is also provided in the indoor master unit 20.
Data of the image information from the outdoor handset 40 and the image information from the indoor handset may be displayed. Further, it goes without saying that the indoor child device 30 may be further provided with an image detecting means. In this case, during the transmission, the transmission can be performed while displaying the image.

In the above embodiment, the visitor data storage means 125 is provided in the indoor parent device 20, but it is needless to say that the visitor data storage means 125 may be provided in another device such as the outdoor child device 40. However, it is more convenient to provide a frequently used device, for example, the indoor parent device 20, when viewing the visitor history. Also,
The contents stored in the visitor data storage means 125 can be viewed only from the indoor parent device 20 itself having the visitor data storage means 125 and from other indoor child devices. Needless to say, it is also possible to access and view the URL.

The visitor data storage means 125 of the above embodiment may be realized by a storage means using an electric element such as an EEPROM or a C-MOS, or by using a recording device such as a video tape recorder. Of course, it is good. Usually, when a storage means such as an EEPROM is used, the storage capacity is limited, but there is an advantage that it is small and easy to incorporate. When a storage means such as a video tape recorder is used, there is an advantage that the storage capacity can be increased although the size is slightly increased. Of course, these storage means may be built in the parent device or the child device, or may be connected and used as an external device.

In the above embodiment, the visitor data storage means 125 stores the image data detected by the image detection means, its date and time data, and the sound data before and after storing the image data. However, any one of them may be stored, such as only image data, or another data may be stored as needed. In addition, as a modification example stored in the visitor data storage unit 125, image data detected by the image detection unit,
A visitor storage data selecting means for selecting the date and time data, the sound data before or after storing the image data, at least one of the data, or a combination thereof is provided, and the visitor data is selected by the user. The type of data stored in the storage means may be selectable. Then, it can be used in an optimal form according to the usage mode of the user.

In the above embodiment, the image detecting means 1
It is needless to say that the image detected by 41 can be stored in either a still image or a moving image. Also,
As another modification, the image of the visitor detected by the image detection means 141 is stored in the visitor data storage means 125 because a means for selecting a still image or a moving image (a changeover switch or the like) is, for example, the indoor master device 20. May be provided so that a still image and a moving image can be selected by the user. It is to be noted that the still image / moving image mode selecting means 151 shown in FIG. 4 performs this selection. In this case, in the case of moving images, the number of visitors that can be stored is reduced because the storage capacity per visitor is increased, but the number of scenes that can be stored as a moving image is increased, and the memory of the visitors is increased. There is an advantage that it can be performed reliably. On the other hand, a still image requires less storage capacity per visitor,
The advantage is that you can remember more visitors.

In the operation of FIG. 3 of the above embodiment, if there is a response from the indoor parent device 20 or the indoor child device 30 in response to the visitor's operation, the visitor data is not stored in the visitor data storage means 125. Like that. As an example of the change, the operation mode shown in the flowchart of FIG.
Indoor parent device 20 or indoor child device 3 depending on the operation of the visitor
A plurality of modes are provided: a mode in which all visitors are stored regardless of whether there is a response of 0, and a mode in which no visitor is stored. Then, for example, the indoor master device 20 is provided with a recording mode selection means for selecting and using at least two modes from the plurality of modes. In this way, a desired mode can be selected and used according to the use situation according to the user's intention. The selection is made by the storage mode selection means 152 shown in FIG.
