PROBLEM TO BE SOLVED: To confirm a doorphone image at any time even during a long absence. SOLUTION: When a video doorphone 21 makes a call operation during absence, an image picked up by a camera of the video doorphone 21 is stored in an image memory 23, and when a radio slave set makes dialing and a call comes to an external line L, it is automatically replied and the image in the image memory 23 is sent to the replied external line L. As a result, the image is sent to the slave radio set via the replied external line and displayed on the display section. Thus, even in the case of absence for a long time, the telephone set can be accessed from the remote location during a stay and the doorphone image can be displayed by means of the slave radio set which is carried, so that the user can confirm the visitors at any time during the absence. |
