When exhibiting products at places such as permanent or emergency showrooms of smartphones or other expensive electronic products or other products, or in places such as department stores or specialty shops, customers can view, touch or demonstrate the electronic products, An alarm device is provided. Such a display alarm device is provided with a charging circuit for supplying power to the electronic product and an alarm circuit for preventing the electronic product from being stolen. It also has an attachment unit attached to the product and is connected to the body via a charging cable or an alarm signal cable.

As described above, the prior art for preventing theft of expensive products displayed for exhibition or demonstration is disclosed in Korean Registered Utility Model No. 20-0365904, Korean Registered Patent No. 10-0899341, Korean Patent Laid-open No. 10-2008 -0090202, and Korean Patent No. 10-0988132.

The piezoelectric sensor may include a piezoelectric sensor that is pressurized by a product displayed on the case, a sensing unit that notifies the control unit that the product displayed on the piezoelectric sensor is removed, an LED that is turned on when the product displayed on the piezoelectric sensor of the case is removed by the sensing unit, And a control unit for driving a speaker and outputting a warning signal, is disclosed in Korean Registered Utility Model No. 20-0365904, which is a product display case for preventing theft and advertisement using sound.

However, in the prior art as described above, a warning signal is output from time to time whenever a customer demonstrates a product on display, giving a sense of rejection to the customer, and an expensive component such as a piezoelectric sensor or the like should be used.

In addition, the 'RFID-based safety management system' for detecting the movement route or the degree of cloudiness based on the RFID and effectively preventing the occurrence of safety accidents by arranging event attendants according to the degree of catchment is disclosed in Korean Patent No. 10-0899341 .

However, although the prior art described above can grasp the movement of people, that is, the degree of cloudiness, by using the RFID, it can not be confirmed whether or not the RFID reader is out of a predetermined range of the RFID reader. In other words, there is a limit in locating the exact position in the public.

In addition, the 'exhibition hall monitoring system', which is equipped with an anti-theft preventing means, an internal camera and an impact detector in a plurality of exhibition display showcases, analyzes and outputs the sensed signals and data sensed by them, Japanese Patent Laid-Open No. 10-2008-0090202.

However, the above-described prior art has a limitation in that it can only observe the act of illegally taking or damaging the exhibits of the exhibition hall while the exhibits of the exhibition hall are controlled so that the customers can not touch or take them. In other words, the above-mentioned prior art can not be confirmed when it is carried out in an obscured state in which the act of taking or destroying the exhibit is not visible.

The terminal unit includes an alarm circuit unit and a communication module. The terminal unit includes an attaching unit that is attached to the product. A sensor that detects whether the product is attached to or detached from the attaching unit.

However, the above-described prior art has a limitation in that a customer can not demonstrate or directly touch a display product because the alarm signal is output even when the display product is detached or brought close to the display product. Also, since the above-mentioned prior art uses various sensors and the like, it takes a lot of cost to manufacture and maintain the theft system.

Most of the customers mentioned above want to try touching or demonstrating products such as smartphones in a store that sells expensive mobile devices such as smartphones without simply being satisfied with their eyesight. As a result, store managers must display smart phones that are not functioning in store shelves (showcases) and high-end smartphones that operate normally.

In this case, since the size of the portable terminal such as a smart phone is small and expensive, there is a problem that customers often take it away from the eyes of the store manager. In order to prevent this, a conventional piezoelectric sensor is used to monitor theft of the smartphone. In this case, the piezoelectric sensor is expensive, and there is a limitation in monitoring the theft of the smartphone that the customer has heard from time to time for the demonstration.
