PROBLEM TO BE SOLVED: To prevent a resident who comes home from being brought face to face with a suspicious person in a dwelling. SOLUTION: An electric lock system 1 transmits a coming-home information to an intercom master unit 3 when the ID information of a contactless key and registered information are in agreement, and an electrical lock 12 is in a locked state. The intercom master unit 3 notifies the detection history of a crime prevention sensor 2 as a voice message from a speaker 41b of a door phone slave unit 4 when coming-home information from the electrical lock system 1 is received.
