[Prior art]

Conventionally, the access control system commonly used in homes, when a person who wants to access the door reaches the door and sends a signal indicating the arrival, the controller inside the door enters and exits through an image transmission device such as a video camera mounted on the door. There is a way to control the opening and closing of the door after confirming the identity of the person who wants to. However, this method is useful for home use where access is limited to a few acquaintances because internal controllers must be able to identify each person.However, offices, laboratories, and other business areas that require frequent access control. It is difficult to apply to the back.

Therefore, if an ID card or the like is issued to a person authorized to enter or exit a specific place, and a card reader is installed at the door, the information (identification information) recorded on the ID card matches the information stored in the card reader, An access control system has been developed and used in which a card reader operates a control device to release a physical lock device mounted on the door. In addition, even if an ID card is not used to improve the access control system, devices for opening and closing the door by recognizing the fingerprint of the accessor and the password inputted by the accessor have been developed. It is equipped with a separate storage device to record the information and access history stored on the ID card of the person.

However, a problem with such an access control system is that if an ID card or the like is stolen, or with the help of an authorized person, not only the unauthorized person can freely enter the control area, but also a malicious third party. If a person who is allowed to enter the area is forced to enter the control area, serious problems in access control may occur, as well as tracking the intruder after death is impossible.

Accordingly, the present invention provides access control using an image that can prevent an unauthorized person and an unauthorized person from coming into a controlled area together or using an stolen card. It is an object to provide a system.

Another object of the present invention is to provide an access control system using an image that can double check the identity of the person.

It is another object of the present invention to provide an access control system using an image which records not only the identification information of the person but also the image data at the same time to facilitate the follow-up of the person.

Another object of the present invention is to provide an access control system which can facilitate access management by recording the identification information of the person and the image data of the person on one screen.
