In order to improve security by limiting visitors authorized to enter, a visitor reception system includes an outdoor unit and a communication terminal capable of communicating with the outdoor unit. The outdoor unit includes a short-range communication portion to communicate with a mobile phone, a communication I/F to communicate with the communication terminal, and a control portion to obtain a telephone number from a mobile phone through the short-range communication portion and transmit the obtained telephone number to the communication terminal through the communication I/F. The communication terminal includes an EEPROM to store a telephone number, a first communication I/F to communicate with the outdoor unit, and a control portion to receive the telephone number of a mobile phone from the outdoor unit through the first communication I/F and give notification of a visitor on condition that the received telephone number is stored in EEPROM.
