Field of the Invention The present invention is applied to, for example, an unmanned store provided with a vending machine, and prevents crime in the store and prevents crime in an unmanned store which can promptly cope with a crime when it occurs. It concerns security systems.

[0002]

2. Description of the Related Art It is well known that with the diversification of lifestyles, many 24-hour convenience stores are opened and the number of customers using the stores is rapidly increasing. Also, recently, in order to further reduce management costs such as labor costs, unmanned convenience stores that are open 24 hours a day and equipped with vending machines have come to appear. In this unmanned convenience store, daily necessities such as food and miscellaneous goods are displayed on the display, and by entering the product number using the keyboard installed in the store, the total amount of personal computers installed in the store is Is calculated and displayed on the display, so that the customer can purchase many kinds of products at a time by putting cash into the cash box.

[0003] The store of this type reflects the era of an increasing population of relatively young generations who have little resistance to the operation of automatic machines, and can reduce the store area. For this reason, it can be introduced even in a city center where there is no space where a manned store can open or a parking area on a highway. In addition, this type of store will be introduced more and more in the future, because it is possible to pass on the reduction of management costs such as reduction of store area and labor cost to products, and it is possible to provide products at lower prices. Have the potential to be In a store that is open 24 hours a day as described above, it is desired to introduce a sufficient security security system that can prevent crime in the store and promptly deal with a crime when it occurs.

In a conventional security security system of this type, a video camera is installed in a store, and images taken by the video camera are sent to a contracted monitoring center to monitor the situation in the store for 24 hours. A limit switch for detecting abnormalities such as prying or impact on vending machines and cash boxes installed in stores or cash boxes, and a shock-related switch are arranged. The operating status of this switch is also sent to the monitoring center to detect abnormalities. Something to do is proposed.
