DOORPHONE UNIT AND RECORDING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a doorphone unit capable of excluding messages of visitors for the purpose of call sales without careful consideration in spite of a limited number of recording items and a limited recording time. SOLUTION: When a depression detection section detects a call button depressed by a visitor, a master control unit of an indoor master unit starts measuring time (S70). Then a voice storage section records the message of the visitor on the condition that the depression detector detects the depression of the call button within a second time after a lapse of a first time (S100), and a human sensing sensor keeps sensing the visitor consecutively from the first depression of the call button.
