PROBLEM TO BE SOLVED: To achieve an interphone function with simplified construction. SOLUTION: The electric lock system 1 possesses an interphone function, and includes an operation panel 3 inside a house for operating to selectively direct on/off of the lock and an electric strike section 13 for making the lock on/off when an operating direction for turning on/off the lock is input from the operation panel 3 or proper information is acquired from outside the house. The electric strike section 13, and the interphone section 15 which has the interphone function and photographs outside situation of the house, are integrally installed in a door frame to construct an electric strike unit 2. The operation panel 3 is capable of mutually communicating with the electric strike unit 2, and stores the image photographed by the interphone section 15 and transferred from the electric strike unit 2, together with historical information, in a storage section 27.
